PERFUME DELIVERY SYSTEMS FOR CONSUMER GOODS
FIELD OF INVENTION
The present invention relates to perfume delivery systems, products comprising
such
systems and the use of same.
BACKGROUND OF THE INVENTION
Products such as consumer products are typically designed and/or formulated to
include a
perfume system. The consumer who selects and uses such a product typically
experiences at
least three product moments of truth. The first moment of truth is typically
at the point of
purchase, the second moment of truth typically begins with the product's
application and use, and
the third moment of truth typically begins immediately after the product's
application and use.
Unfortunately, current perfume delivery systems do not always provide the most
preferred or
ideal sensory experience during such moments of truth. Thus, there is a need
for one or more
perfume delivery systems that obviate the short comings of the current perfume
delivery
technologies. The perfume systems of the present invention meet the
aforementioned need.

Perfume Delivery Systems
The consumer who selects and uses such a perfumed product makes critical
decisions as to how
satisfied he or she is with the product at multiple touch points in the
product usage profile.
Although numerous touch points are known, Applicants have found that they can
be
advantageously grouped and expressed as three product moments of truth that
are experienced by
the typically consumer. The FMOT is typically at the point of purchase, the
SMOT typically
begins with the product's application and use, and the TMOT typically begins
immediately after
the product's application and use. Applicants have recognized that a
consumer's FMOT is
negatively impacted because the product packaging inhibits the sensory
experience; for example,
product packaging may make the product difficult to open or, when open,
exposes a product that
can spill. In addition, formulation ingredients can suppress and/or distort
neat product odor.
Furthermore Applicants have recognized that the consumer's SMOT is negatively
impacted as
volatile PRMs are lost during product storage, resulting in reduced bloom
during use.
Compensating for these aforementioned deficiencies by adding high perfume
levels for the
TMOT can distort in-use scent experience, such that the perfume bloom can be
too harsh or
strong, and/or the perfume character can become less preferred. Also,
Applicants have
recognized that a consumer's FMOT is negatively impacted as perfume releases
from the treated
situs, inter alia a dry fabric over long period of time requires perfume
levels in product that
would distort the scent experience during the first and second moments of
truth. Furthermore,
addition of high perfume levels for SMOT & TMOT can distort neat product odor,
and still not
result in sufficient perfume deposition through the wash. In addition, perfume
evaporation that
occurs during drying can result in lower perfume levels on fabric; and/or the
perfume remaining
on dry fabric may provide initial dry fabric odor benefit but such perfume can
dissipate too
quickly to provide sufficient scent longevity benefits. Furthermore, perfume
that is present on
fabric may release too slowly from the fabric. As mentioned, the same can be
the case with
perfume delivery to and release from other situs such as hair and skin. The
ability to notice the
release of perfume can be impacted by a variety of factors such as hair
length, clothing worn over
skin, situs wash frequency, and the like. Variable deposition and release
during the wash or rinse
or application can be another deficiency that can negatively impact the scent
experience during
the different moments of truth. The number of treatments or applications can
also have an
{
CA 02691340 2010-01-27
1 - 11249/SK
5 impact, for example, wherein a different intensity and/or character is
achieved after the first wash
compared to after subsequent washes of a particular situs. Furthermore,
perfume intensity and/or
character may be perceived differently on wet situs compared to dry situs that
is treated with
perfume-containing products. Without wishing to be bound by theory, in
addition to loss of
perfume by evaporation during drying, perfume can be made less available at
certain touch points
by being carried into or partitioning into the situs, such as cotton fibers,
hair, skin, and the like.
Situs moisture level can also serve to alter the release profile or release
rate of perfume.
Finally, Applicants recognized that solutions to the problems that are
associated with one
or two moments of truth can be insufficient to resolve the problems associated
with the
remaining moment(s) of truth or negatively impact the other moment(s) of truth
The following perfume delivery technologies (PDTs) also known as perfume
delivery
systems may be used in any combination in any type of consumer product:
Polymer Assisted Delivery (PAD): This perfume delivery technology uses
polymeric materials
to deliver perfume materials. Classical coacervation, water soluble or partly
soluble to insoluble
charged or neutral polymers, liquid crystals, hot melts, hydrogels, perfumed
plastics,
microcapsules, nano- and micro-latexes, polymeric film formers, and polymeric
absorbents,
polymeric adsorbents, etc. are some examples. PAD includes but is not limited
to:
Matrix Systems: The fragrance is dissolved or dispersed in a polymer matrix or
particle.
Perfumes, for example, may be 1) dispersed into the polymer prior to
formulating into the
product or 2) added separately from the polymer during or after formulation of
the product.
Diffusion of perfume from the polymer is a common trigger that allows or
increases the rate
of perfume release from a polymeric matrix system that is deposited or applied
to the desired
surface (situs), although many other triggers are know that may control
perfume release.
Absorption and/or adsorption into or onto polymeric particles, films,
solutions, and the like
are aspects of this technology. Nano- or micro-particles composed of organic
materials (e.g.,
latexes) are examples. Suitable particles include a wide range of materials
including, but not
limited to polyacetal, polyacrylate, polyacrylic, polyacrylonitrile,
polyamide,
polyaryletherketone, polybutadiene, polybutylene, polybutylene terephthalate,
polychloroprene, poly ethylene, polyethylene terephthalate, polycyclohexylene
dimethylene
terephthalate, polycarbonate, polychloroprene, polyhydroxyalkanoate,
polyketone, polyester,
polyethylene, polyetherimide, polyethersulfone, polyethylenechlorinates,
polyimide,
polyisoprene, polylactic acid, polymethylpentene, polyphenylene oxide,
polyphenylene
sulfide, polyphthalamide, polypropylene, polystyrene, polysulfone, polyvinyl
acetate,

s polyvinyl chloride, as well as polymers or copolymers based on acrylonitrile-
butadiene,
cellulose acetate, ethylene-vinyl acetate, ethylene vinyl alcohol, styrene-
butadiene, vinyl
acetate-ethylene, and mixtures thereof.
"Standard" systems refer to those that are "pre-loaded" with the intent of
keeping the pre-
loaded perfume associated with the polymer until the moment or moments of
perfume
release. Such polymers may also suppress the neat product odor and provide a
bloom and/or
longevity benefit depending on the rate of perfume release. One challenge with
such systems
is to achieve the ideal balance between 1) in-product stability (keeping
perfume inside carrier
until you need it) and 2) timely release (during use or from dry situs).
Achieving such
stability is particularly important during in-product storage and product
aging. This
challenge is particularly apparent for aqueous-based, surfactant-containing
products, such as
heavy duty liquid laundry detergents. Many "Standard" matrix systems available
effectively
become "Equilibrium" systems when formulated into aqueous-based products. One
may
select an "Equilibrium" system or a Reservoir system, which has acceptable in-
product
diffusion stability and available triggers for release (e.g., friction).
"Equilibrium" systems are
those in which the perfume and polymer may be added separately to the product,
and the
equilibrium interaction between perfume and polymer leads to a benefit at one
or more
consumer touch points (versus a free perfume control that has no polymer-
assisted delivery
technology). The polymer may also be pre-loaded with perfume; however, part or
all of the
perfume may diffuse during in-product storage reaching an equilibrium that
includes having
desired perfume raw materials (PRMs) associated with the polymer. The polymer
then
carries the perfume to the surface, and release is typically via perfume
diffusion. The use of
such equilibrium system polymers has the potential to decrease the neat
product odor
intensity of the neat product (usually more so in the case of pre-loaded
standard system).
Deposition of such polymers may serve to "flatten" the release profile and
provide increased
longevity. As indicated above, such longevity would be achieved by suppressing
the initial
intensity and may enable the formulator to use more high impact or low odor
detection
threshold (ODT) or low Kovats Index (KI) PRMs to achieve FMOT benefits without
initial
intensity that is too strong or distorted. It is important that perfume
release occurs within the
time frame of the application to impact the desired consumer touch point or
touch points.
Suitable micro-particles and micro-latexes as well as methods of making same
may be found
in USPA 2005/0003980 Al. Matrix systems also include hot melt adhesives and
perfume
plastics. In addition, hydrophobically modified polysaccharides may be
formulated into the
CA 02691340 2010-01-27
' = 11249/SK
7
perfumed product to increase perfume deposition and/or modify perfume release.
All such
matrix systems, including for example polysaccarides and nanolatexes may be
combined with
other PDTs, including other PAD systems such as PAD reservoir systems in the
form of a
perfume microcapsule (PMC). Polymer Assisted Delivery (PAD) matrix systems may
include those described in the following references: US Patent Applications
2004/0110648

6,024,943; 6,042,792; 6,051,540; 4,540,721 and 4,973,422.
Silicones are also examples of polymers that may be used as PDT, and can
provide perfume
benefits in a manner similar to the polymer-assisted delivery "matrix system".
Such a PDT is
referred to as silicone-assisted delivery (SAD). One may pre-load silicones
with perfume, or
use them as an equilibrium system as described for PAD. Suitable silicones as
well as
making same may be found in WO 2005/102261; USPA 20050124530A1; USPA
20050143282A1; and WO 2003/015736. Functionalized silicones may also be used
as
described in USPA 2006/003913 Al. Examples of silicones include
polydimethylsiloxane
and polyalkyldimethylsiloxanes. Other examples include those with amine
functionality,
which may be used to provide benefits associated with amine-assisted delivery
(AAD) and/or
polymer-assisted delivery (PAD) and/or amine-reaction products (ARP). Other
such
examples may be found in USP 4,911,852; USPA 2004/0058845 Al; USPA
2004/0092425
Al and USPA 2005/0003980 Al.
Reservoir Systems: Reservoir systems are also known as a core-shell type
technology, or one in
which the fragrance is surrounded by a perfume release controlling membrane,
which may serve
as a protective shell. The material inside the microcapsule is referred to as
the core, internal
phase, or fill, whereas the wall is sometimes called a shell, coating, or
membrane. Microparticles
or pressure sensitive capsules or microcapsules are examples of this
technology. Microcapsules
of the current invention are formed by a variety of procedures that include,
but are not limited to,
coating, extrusion, spray-drying, interfacial, in-situ and matrix
polymerization. The possible
shell materials vary widely in their stability toward water. Among the most
stable are
polyoxymethyleneurea (PMU)-based materials, which may hold certain PRMs for
even long
periods of time in aqueous solution (or product). Such systems include but are
not limited to
urea-formaldehyde and/or melamine-formaldehyde. Gelatin-based microcapsules
may be
prepared so that they dissolve quickly or slowly in water, depending for
example on the degree of
CA 02691340 2010-01-27
11249/SK
8
cross-linking. Many other capsule wall materials are available and vary in the
degree of perfume
diffusion stability observed. Without wishing to be bound by theory, the rate
of release of
perfume from a capsule, for example, once deposited on a surface is typically
in reverse order of
in-product perfume diffusion stability. As such, urea-formaldehyde and
melamine-formaldehyde
microcapsules for example, typically require a release mechanism other than,
or in addition to,
diffusion for release, such as mechanical force (e.g., friction, pressure,
shear stress) that serves to
break the capsule and increase the rate of perfume (fragrance) release. Other
triggers include
melting, dissolution, hydrolysis or other chemical reaction, electromagnetic
radiation, and the
like. The use of pre-loaded microcapsules requires the proper ratio of in-
product stability and in-
use and/or on-surface (on-situs) release, as well as proper selection of PRMs.
Microcapsules that
are based on urea-formaldehyde and/or melamine-formaldehyde are relatively
stable, especially
in near neutral aqueous-based solutions. These materials may require a
friction trigger which
may not be applicable to all product applications. Other microcapsule
materials (e.g., gelatin)
may be unstable in aqueous-based products and may even provide reduced benefit
(versus free
perfume control) when in-product aged. Scratch and sniff technologies are yet
another example
of PAD. Perfume microcapsules (PMC) may include those described in the
following references:

6,106,875 and
4,234,627, 3,594,328 and US RE 32713.
Molecule-Assisted Delivery (MAD): Non-polymer materials or molecules may also
serve to
improve the delivery of perfume. Without wishing to be bound by theory,
perfume may non-
covalently interact with organic materials, resulting in altered deposition
and/or release. Non-
limiting examples of such organic materials include but are not limited to
hydrophobic materials
such as organic oils, waxes, mineral oils, petrolatum, fatty acids or esters,
sugars, surfactants,
liposomes and even other perfume raw material (perfume oils), as well as
natural oils, including
body and/or other soils. Perfume fixatives are yet another example. In one
aspect, non-
polymeric materials or molecules have a CLogP greater than about 2. Molecule-
Assisted
Delivery (MAD) may also include those described in USP 7,119,060 and USP
5,506,201.

Fiber-Assisted Delivery (FAD): The choice or use of a situs itself may serve
to improve the
delivery of perfume. In fact, the situs itself may be a perfume delivery
technology. For example,
different fabric types such as cotton or polyester will have different
properties with respect to
ability to attract and/or retain and/or release perfume. The amount of perfume
deposited on or in
fibers may be altered by the choice of fiber, and also by the history or
treatment of the fiber, as
well as by any fiber coatings or treatments. Fibers may be woven and non-woven
as well as
natural or synthetic. Natural fibers include those produced by plants,
animals, and geological
processes, and include but are not limited to cellulose materials such as
cotton, linen, hemp jute,
flax, ramie, and sisal, and fibers used to manufacture paper and cloth. Fiber-
Assisted Delivery
may consist of the use of wood fiber, such as thermomechanical pulp and
bleached or unbleached
kraft or sulfite pulps. Animal fibers consist largely of particular proteins,
such as silk, sinew,
catgut and hair (including wool). Polymer fibers based on synthetic chemicals
include but are
not limited to polyamide nylon, PET or PBT polyester, phenol-formaldehyde
(PF), polyvinyl
alcohol fiber (PVOH), polyvinyl chloride fiber (PVC), polyolefins (PP and PE),
and acrylic
polymers. All such fibers may be pre-loaded with a perfume, and then added to
a product that
may or may not contain free perfume and/or one or more perfume delivery
technologies. In one
aspect, the fibers may be added to a product prior to being loaded with a
perfume, and then
loaded with a perfume by adding a perfume that may diffuse into the fiber, to
the product.
Without wishing to be bound by theory, the perfume may absorb onto or be
adsorbed into the
fiber, for example, during product storage, and then be released at one or
more moments of truth
or consumer touch points.
Amine Assisted Delivery (AAD): The amine-assisted delivery technology approach
utilizes
materials that contain an amine group to increase perfume deposition or modify
perfume release
during product use. There is no requirement in this approach to pre-complex or
pre-react the
perfume raw material(s) and amine prior to addition to the product. In one
aspect, amine-
containing AAD materials suitable for use herein may be non-aromatic; for
example,
polyalkylimine, such as polyethyleneimine (PEI), or polyvinylamine (PVAm), or
aromatic, for
example, anthranilates. Such materials may also be polymeric or non-polymeric.
In one aspect,
such materials contain at least one primary amine. This technology will allow
increased
longevity and controlled release also of low ODT perfume notes (e.g.,
aldehydes, ketones,
enones) via amine functionality, and delivery of other PRMs, without being
bound by theory, via
polymer-assisted delivery for polymeric amines. Without technology, volatile
top notes can be
CA 02691340 2010-01-27
' = 11249/SK
5 lost too quickly, leaving a higher ratio of middle and base notes to top
notes. The use of a
polymeric amine allows higher levels of top notes and other PRMS to be used to
obtain freshness
longevity without causing neat product odor to be more intense than desired,
or allows top notes
and other PRMs to be used more efficiently. In one aspect, AAD systems are
effective at
delivering PRMs at pH greater than about neutral. Without wishing to be bound
by theory,
10 conditions in which more of the amines of the AAD system are deprotonated
may result in an
increased affinity of the deprotonated amines for PRMs such as aldehydes and
ketones, including
unsaturated ketones and enones such as damascone. In another aspect, polymeric
amines are
effective at delivering PRMs at pH less than about neutral. Without wishing to
be bound by
theory, conditions in which more of the amines of the AAD system are
protonated may result in a
decreased affinity of the protonated amines for PRMs such as aldehydes and
ketones, and a
strong affinity of the polymer framework for a broad range of PRMs. In such an
aspect,
polymer-assisted delivery may be delivering more of the perfume benefit; such
systems are a
subspecies of AAD and may be referred to as Amine- Polymer-Assisted Delivery
or APAD. In
some cases when the APAD is employed in a composition that has a pH of less
than seven, such
APAD systems may also be considered Polymer-Assisted Delivery (PAD). In yet
another aspect,
AAD and PAD systems may interact with other materials, such as anionic
surfactants or
polymers to form coacervate and/or coacervates-like systems. In another
aspect, a material that
contains a heteroatom other than nitrogen, for example sulfur, phosphorus or
selenium, may be
used as an alternative to amine compounds. In yet another aspect, the
aforementioned alternative
compounds can be used in combination with amine compounds. In yet another
aspect, a single
molecule may comprise an amine moiety and one or more of the alternative
heteroatom moieties,
for example, thiols, phosphines and selenols. Suitable AAD systems as well as
methods of
making same may be found in US Patent Applications 2005/0003980 Al;
2003/0199422 Al;
2003/0036489 Al; 2004/0220074 Al and USP 6,103,678.
Cyclodextrin (CD): This technology approach uses a cyclic oligosaccharide or
cyclodextrin to
improve the delivery of perfume. Typically a perfume and cyclodextrin (CD)
complex is formed.
Such complexes may be preformed, formed in-situ, or formed on or in the situs.
Without
wishing to be bound by theory, loss of water may serve to shift the
equilibrium toward the CD-
Perfume complex, especially if other adjunct ingredients (e.g., surfactant)
are not present at high
concentration to compete with the perfume for the cyclodextrin cavity. A bloom
benefit may be
achieved if water exposure or an increase in moisture content occurs at a
later time point. In
CA 02691340 2010-01-27
11249/SK
I1
addition, cyclodextrin allows the perfume formulator increased flexibility in
selection of PRMs.
Cyclodextrin may be pre-loaded with perfume or added separately from perfume
to obtain the
desired perfume stability, deposition or release benefit. Suitable CDs as well
as methods of
making same may be found in USPA 2005/0003980 Al and 2006/0263313 Al and US
Patents
5,552,378; 3,812,011; 4,317,881; 4,418,144 and 4,378,923.
Starch Encapsulated Accord (SEA): The use of a starch encapsulated accord
(SEA)
technology allows one to modify the properties of the perfume, for example, by
converting a
liquid perfume into a solid by adding ingredients such as starch. The benefit
includes increased
perfume retention during product storage, especially under non-aqueous
conditions. Upon
exposure to moisture, a perfume bloom may be triggered. Benefits at other
moments of truth
may also be achieved because the starch allows the product formulator to
select PRMs or PRM
concentrations that normally cannot be used without the presence of SEA.
Another technology
example includes the use of other organic and inorganic materials, such as
silica to convert
perfume from liquid to solid. Suitable SEAs as well as methods of making same
may be found in
USPA 2005/0003980 Al and USP 6,458,754 B1.
Zeolite & Inorganic Carrier (ZIC): This technology relates to the use of
porous zeolites or
other inorganic materials to deliver perfumes. Perfume-loaded zeolite may be
used with or
without adjunct ingredients used for example to coat the perfume-loaded
zeolite (PLZ) to change
its perfume release properties during product storage or during use or from
the dry situs. Suitable
zeolite and inorganic carriers as well as methods of making same may be found
in USPA
2005/0003980 Al and US Patents 5,858,959; 6,245,732 B1; 6,048,830 and
4,539,135. Silica is
another form of ZIC. Another example of a suitable inorganic carrier includes
inorganic tubules,
where the perfume or other active material is contained within the lumen of
the nano- or micro-
tubules. Preferably, the perfume-loaded inorganic tubule (or Perfume-Loaded
Tubule or PLT) is
a mineral nano- or micro-tubule, such as halloysite or mixtures of halloysite
with other inorganic
materials, including other clays. The PLT technology may also comprise
additional ingredients

Pro-Perfume (PP): This technology refers to perfume technologies that result
from the reaction
of perfume materials with other substrates or chemicals to form materials that
have a covalent
bond between one or more PRMs and one or more carriers. The PRM is converted
into a new
material called a pro-PRM (i.e., pro-perfume), which then may release the
original PRM upon
exposure to a trigger such as water or light. Pro-perfumes may provide
enhanced perfume
delivery properties such as increased perfume deposition, longevity,
stability, retention, and the
like. Pro-perfumes include those that are monomeric (non-polymeric) or
polymeric, and may be
pre-formed or may be formed in-situ under equilibrium conditions, such as
those that may be
present during in-product storage or on the wet or dry situs. Nonlimiting
examples of pro-
perfumes include Michael adducts (e.g., beta-amino ketones), aromatic or non-
aromatic imines
(Schiff bases), oxazolidines, beta-keto esters, and orthoesters. Another
aspect includes
compounds comprising one or more beta-oxy or beta-thio carbonyl moieties
capable of releasing
a PRM, for example, an alpha, beta-unsaturated ketone, aldehyde or carboxylic
ester. The typical
trigger for perfume release is exposure to water; although other triggers may
include enzymes,
heat, light, pH change, autoxidation, a shift of equilibrium, change in
concentration or ionic
strength and others. For aqueous-based products, light-triggered pro-perfumes
are particularly
suited. Such photo-pro-perfumes (PPPs) include but are not limited to those
that release
coumarin derivatives and perfumes and/or pro-perfumes upon being triggered.
The released pro-
perfume may release one or more PRMs by means of any of the above mentioned
triggers. In
one aspect, the photo-pro-perfume releases a nitrogen-based pro-perfume when
exposed to a light
and/or moisture trigger. In another aspect, the nitrogen-based pro-perfume,
released from the
photo-pro-perfume, releases one or more PRMs selected, for example, from
aldehydes, ketones
(including enones) and alcohols. In still another aspect, the PPP releases a
dihydroxy coumarin
derivative. The light-triggered pro-perfume may also be an ester that releases
a coumarin
derivative and a perfume alcohol. In one aspect the pro-perfume is a
dimethoxybenzoin
derivative as described in USPA 2006/0020459 Al. In another aspect the pro-
perfume is a 3',
5'-dimethoxybenzoin (DMB) derivative that releases an alcohol upon exposure to
electromagnetic radiation. In yet another aspect, the pro-perfume releases one
or more low ODT
PRMs, including tertiary alcohols such as linalool, tetrahydrolinalool, or
dihydromyrcenol.

Amine Reaction Product (ARP): For purposes of the present application, ARP is
a subclass
or species of PP. One may also use "reactive" polymeric amines in which the
amine
functionality is pre-reacted with one or more PRMs to form an amine reaction
product
(ARP). Typically the reactive amines are primary and/or secondary amines, and
may be part
of a polymer or a monomer (non-polymer). Such ARPs may also be mixed with
additional
PRMs to provide benefits of polymer-assisted delivery and/or amine-assisted
delivery.
Nonlimiting examples of polymeric amines include polymers based on
polyalkylimines, such
as polyethyleneimine (PEI), or polyvinylamine (PVAm). Nonlimiting examples of
monomeric (non-polymeric) amines include hydroxyl amines, such as 2-
aminoethanol and its
alkyl substituted derivatives, and aromatic amines such as anthranilates. The
ARPs may be
premixed with perfume or added separately in leave-on or rinse-off
applications. In another
aspect, a material that contains a heteroatom other than nitrogen, for example
oxygen, sulfur,
phosphorus or selenium, may be used as an alternative to amine compounds. In
yet another
aspect, the aforementioned alternative compounds can be used in combination
with amine
compounds. In yet another aspect, a single molecule may comprise an amine
moiety and one
or more of the alternative heteroatom moieties, for example, thiols,
phosphines and selenols.
The benefit may include improved delivery of perfume as well as controlled
perfume release.
Suitable ARPs as well as methods of making same can be found in USPA
2005/0003980 Al
and USP 6,413,920 B 1.
Perfume Design (PD): The rational design of perfumes and/or perfume accords in
which the
physical properties of the perfume raw materials are utilized to create
functional perfumes is also
considered a perfume delivery technology. Such perfume design may be used with
or without
one or more technologies described above. When used with or without one or
more of the above
technologies, the technology may also be referred to as "free perfume". Non-
limiting properties
that may be used in perfume design include, but are not limited to, octanol-
water partition
coefficient (LogP or CLopP), water solubility parameters, boiling point (bp),
Kovats Index (KI)
value, solvent-accessible surface area, and others. The odor detection
threshold (ODT) value
may also be used to design perfumes or perfume accords with preferred
olfactive properties, and
which may compliment or enable the use of one or more other perfume delivery
technologies.

Suitable perfume design (PD) systems and methods of making same can be found
in US Patents
2007/0042934 Al, 2005/0003980 Al, 2007/0071780 Al, and USP 6,998,382.
When such technologies are used in combination, such technologies may employ
the same or different perfume and/or perfume accords. While not being bound by
theory, it is
believed that when a single perfume composition is used for all delivery
technologies, including
any neat perfume that is applied to a product, the consumer is provided with a
consistent odor
experience during all three moments of truth. Suitable perfume raw materials
and accords, for
use in the technologies described herein, may be obtained from one or more of
the following

In the aforementioned aspects, multiple FMOT technologies may be employed as
the
experience provided by a single FMOT technology may, at times, be insufficient
to meet all the
needs of the consumer. For example, the perfume release provided by a single
packaging
approach or FMOT perfume delivery technology (PDT) may not be experienced or
noticed by
every consumer. For example, one consumer may lift a product's cap and
experience the benefit
of a FMOT PDT, such as a matrix-based polymer-assisted delivery (PAD)
technology (for
example, a perfume hot melt or a perfumed plastic insert); however another
consumer may not
decide to lift the cap, and would instead be more likely to notice a FMOT PDT
that is positioned
on the outside of the product or package. Such a FMOT PDT could be selected
from the list
comprising 1) PAD matrix type hot melts, 2) perfume injected plastic, 3)
perfumed labels, 4)
scratch & sniff perfume release systems, or even 5) perfume samplers that are
present in the
proximity of the product, such as part of a store display. Any of these FMOT
PDTs could be
independently selected, and be independently positioned on the product, such
as on the top, side
or bottom of the product and/or package.
Another example of a solution to this need for improved FMOT experience is
using a
same or similar PDT, such as perfume hot melts, but such that the same or
similar PDT is present
in more than one location on the product. For example, the hot melt could be
present under the
lid of the product and the same or different FMOT PDT could be on the bottom
of the product.
Based on the desired experience, the perfume selected for incorporation into
one FMOT PDT
(e.g., hot melt or perfumed plastic insert) may be the same, may be similar or
may be different in
perfume composition as the perfume selected for incorporation into one or more
other hot melts
contained as part of the product and/or product packaging.
CA 02691340 2010-01-27
11249/SK
29
Hot melt or adhesive-based systems will release perfume raw materials (PRMs)
at a
different rate than alternative FMOT PDTs such as perfume injected plastics or
the like. The
difference in perfume release profiles can be leveraged to provide greater
olfactive benefit than
for a single PDT in which certain compromises would need to be struck by the
perfumer or
product formulator in order to balance factors such as character, intensity,
release profile, cost,
and the like. For example, one combination option is to include the same FMOT
PDT on
different parts of the product but select different perfume accords for
different samples. For
example, one FMOT PDT could contain a higher percentage of top notes with a
Kovats index
(KI) value in the range of 800 to 1200, whereas another hot melt might contain
more middle
notes or PRMs with a Kovats index (KI) value in the range of 1200-1500,
whereas yet another
might contain base notes with a Kovats index (KI) value >1500. This would have
the advantage
of allowing one to select the perfume loading based on release profile of the
PRMs, which have
different volatilities.
For any of the FMOT PDTs, such as hot melts or perfume plastics, the system
can be
improved by selecting key PRMs for release that are based on combination of
parameters such as
Kovats Index (KI) and Odor Detection Threshold (ODT). Preferred range of KI
for PRMS may
be from 800 to 1500, more preferably from 1000 to 1400, even more preferably
from 1000 to
1200. In addition, one may choose individual PRMs or perfume accords to
enhance the scent of
the perfume in the product. These PRMs may be selected from those PRMs that
may not be easy
to formulate due to chemical instability, for example. Other examples of
perfume design in
which different PRMs or accords are selected for different FMOT PDTs and/or
the perfume in
the product also fall within the scope of this invention.
Another aspect of the present invention includes the use of combinations of
FMOT PDTs
to provide a desired experience at the point of purchase for products that
contain low perfume
levels, or no perfume. Such products may be chosen by the consumer to minimize
exposure to
perfume during in-use experience of for the dry situs. Such products with low
in-product
perfume levels may have an undesired odor due to the rest of the formulation
ingredients. As
such, the FMOT PDT or PDTs may be used to improve the scent experience at the
point of
purchase.
In the aforementioned aspects, it is also important for the consumer to have
an ideal scent
experience when using the product. For example, the consumer should be pleased
by the fresh
character and preferred intensity of the scent of the product during use.
While FMOT PDT or
PDTs typically serve the need of providing the desired sensory experience at
point of purchase,
CA 02691340 2010-01-27
11249/SK
5 they may not deliver throughout the in-use experience, for example, because
the product may be
put away during use, or the treated situs is put away before use, or the scent
intensity may be
insufficient in strength to meet the consumer need during use. In addition,
the multiple consumer
touch points during the in-use experience may require additional PDTs to drive
the desired
sensory experience. For example, one SMOT PDT may be needed to provide desired
product
10 scent experience when opening package and/or when pouring the product out
of box or bottle,
and another SMOT PDT to maintain the desired scent intensity and character of
the wash
solution. In addition, the same or different SMOT PDT(s) may be selected to
provide scent that
fills and lingers in the room in which the product is being used, as well as,
to provide scent to the
treated situs. For example, in the case of a laundry detergent or fabric
conditioners, the SMOT
15 PDT can provide a desired scent experience on the wet laundry, particularly
when it is taken out
of the washer. For consumers that wash fabrics by hand, such in-use perfume
release (a.k.a.,
perfume bloom) is particularly important to the scent experience. Other
examples include hair
and skin care products, including but not limited to, hair shampoos and
conditioners, body
washes, including those with one or more separate phases, bar soaps,
antiperspirants, deodorants,
20 and the like. For such products, the perfume bloom during the use of the
product in its neat or
water-diluted form is important to the SMOT consumer experience.
Using SMOT PDT or PDTs may provide increased perfume intensity or perfume
bloom
during product use, including in cases in which the perfume release is
triggered by moisture, such
that the scent may be experienced, even filling the room, when the product
package is not present
25 or when the FMOT PDT is not providing sufficient scent in combination with
the perfume
associated with the neat product.
Any of the PDTs described within may be used in any combination in a consumer
product
to achieve the desired FMOT or SMOT scent experience. Examples of SMOT PDTs
include
starch encapsulated accords, cyclodextrin, pro-perfumes, perfume-loaded
polymers, which
30 include matrix (e.g., nanolatex) and reservoir (microcapsule) systems.
SMOT PDTs in which perfume release is triggered by an increase in moisture
during
product use are particularly suited for low moisture product forms for example
granular
detergents, fabric softener sheets, laundry tablets, and the like.
In many cases, SMOT PDTs may decrease the neat product odor (NPO) or perfume
headspace above the product, without being bound by theory, due to the
interaction between the
carrier and the perfume raw materials (PRMs). One skilled in the art can
attempt to compensate
for the loss of perfume headspace by adding additional free perfume; however,
this approach can
CA 02691340 2010-01-27
11249/SK
31
add to the expense of the product and can negatively impact the consumer
experience at other
consumer touch points by causing the scent to be distorted either in terms of
character or
intensity. The use of the present invention, which combines FMOT and SMOT
PDTs, may
address the problem caused by the use of said SMOT or TMOT PDT that is
intended to provide
benefit during or after product use. For example, cyclodextrin and/or SEA may
be individually
loaded with perfume and formulated into a granular laundry detergent, which
may provide a
burst or bloom of perfume intensity upon product use. The scent intensity and
character of the
neat product, however, may be insufficient or distorted in such a way as to
decrease consumer
acceptance at the FMOT (point of purchase). As such, addition of a FMOT PDT
solves the
problem by allowing the formulator to improve the overall scent experience.
This may include a
small amount of perfume present on the product or package that is closer in
scent character to the
scent of the wash solution once some or all of the perfume is released from
the SMOT PDT.
Alternatively, a perfume with a different character and intensity may be
selected for
incorporation into the FMOT PDT.
In another aspect, a means to overcome the challenge of the consumer becoming
tired of
the same scent being detected from the neat product odor, to the in-use
experience, and even to
the after use experience is disclosed. This invention allows one to provide
different perfume
characters at each consumer touch point. Thus, the perfume of the packaging
material may be
different than the perfume in the bottle and optionally different from the
perfume released during
product use and optionally different from the perfume that is released from
the wet situs or from
the delivery system releasing perfume from the wet or dry situs after product
use. Thus, it
enables the formulator to balance the overall scent experience of the consumer
by combining any
or all of the following PDT(s) described herein.
Another advantage of the present invention is that the release profile or
release rate may
be modified by using combinations of FMOT and SMOT PDTs. A particular PRM may
have
properties that make it difficult to provide a desired headspace level, for
example, if the PRM has
a low vapor pressure when present with other formulation ingredients such as
surfactant. The use
of a FMOT PDT may allow such PRMs to be present in the headspace near the
product such that
the benefit of said PRM may be realized.
Employing multiple SMOT PDTS may be useful. Although certain perfume carriers
are
effective at complexing a broad range of PRMs, many are limited by which PRMs
are fully
complexed. Such limitations may be associated with molecular size or shape,
for example. In
such cases, it is necessary to compliment a given SMOT PDT with additional
SMOT PDTs. For
i
CA 02691340 2010-01-27
11249/SK
32
example, for certain highly volatile PRMs, there may be loses during the
starch encapsulation
process. Such PRMs however may be more readily incorporated in cyclodextrin,
especially if
they have a high binding constant. As such, the combination of SEA and CD in a
product may
provide greater scent benefits in terms of character and intensity than either
could provide
separately.
Although products utilizing FMOT PDT(s) may improve consumer experience at
point of
purchase, and SMOT PDTs may provide an improved in-use experience, there is
also a need to
improve scent of the dry situs. For example, there is an unmet need to provide
improved dry
fabric odor (DFO), both in terms of scent character and intensity. Thus, TMOT
PDTs are useful.
For many TMOT PDTs there is a strong interaction between the carrier and the
perfume. In
order to achieve improved situs odor, it is necessary to increase deposition
of PRMs onto the
situs. This may be achieved by using a carrier technology, however this
carrier may suppress
neat product odor, such that the FMOT experience is distorted. This problem is
solved by the
current invention in which the overall experience is enhanced by using FMOT
PDT(s) in
combination with TMOT PDT(s).
For example, the encapsulation of perfume by a polymer wall or matrix allows
the
perfume to be protected from harsh product conditions and allows increased
perfume deposition
to the situs. Without being bound by theory, the encapsulation technology can
suppress the
perfume headspace prior to the release of the perfume from the carrier due to
a trigger. Such
triggers include but are not limited to diffusion, friction, heat, dilution,
ionic strength, water, pH,
light, and the like. The suppression of perfume headspace can lead to a
distortion of the neat
product odor and the FMOT consumer experience. The use of a FMOT PDT solves
this problem
by improving the character and intensity at the earlier consumer touch point
or moment of truth,
and using the TMOT PDT(s) to provide benefits to the treated situs, for
example DFO.
Similar to perfume microcapsules (PMCs), the use of FMOT PDT may provide
similar
advantage when using other TMOT PDTs described in this application. These
include, but are
not limited to, pro-perfumes, perfume-loaded zeolites (PLZ), other polymer-
assisted delivery
systems, such as nanolatex, amine-assisted delivery technologies, and
nanotubules.
Employing multiple TMOT PDTs may be useful. There are many consumer touch
points
associated with TMOT that often will require the use of more than one PDT to
satisfy the
consumer need. For example, for fabric applications, different TMOT PDTs may
be required to
improve character and intensity of dry or nearly dry laundry as it is 1)
removed from the dryer, 2)
taken off the drying line, 3) folded and stored, 4) ironed, 5) freshly put on,
6) smelled by the
i . . . . . . . . . .
CA 02691340 2010-01-27
11249/SK
33
consumer or others after hours of wearing, 7) re-worn after having been worn
or used previously,
and 8) removed from the dirty laundry pile prior to laundering. Another
example includes hair or
skin (or scalp) applications, wherein different TMOT PDTs may be required to
improve character
and intensity of dry or nearly dry hair or skin as the consumer is noticing
the scent of the perfume
on themselves or others 1) during or after drying off, for example, with a
towel and/or hair or
hand dryer following the use of the product for washing, bathing, showering or
the like, 2) after
exiting the room or area in which the product was used (e.g., bathroom or
shower), 3) after
retuming to the location the product was used, 4) after hours since the use of
the product, or 5)
after one or more days since the use of the product. Other consumer touch
points associated with
TMOT include, but are not limited to, the scent on fabric after using hair or
skin products,
including antiperspirants and deodorants, and the change in scent intensity
and/or character that
may be associated with changes in the moisture content of a situs. All of the
above consumer
touch points can be addressed using combinations of perfume delivery
technologies that provide
a benefit after a single use or application or after multiple uses or
applications.
It is not uncommon for certain PRMs to "leak" out of perfume microcapsules
(PMC)
during product storage or during product use. This invention describes a means
to use a PDT to
interact with or "scavenge" PRMs that may be delivered with less efficiency as
desired by the
PMC, to provide a superior perfume experience compared to using a PMC or a PAD
individually. For some PMC systems, PRMs that leak most readily include those
with low
CLogP value and/or low Kovats Index (KI) value, including PRMs that are
referred to as "top
notes"; PAD and AAD PDTs may be used to improve the delivery of such PRMs.
Another
option to leverage TMOT combinations is to add additional free PRMs, including
top notes,
separately from the PMC, and use a PAD and/or AAD technology to improve the
deposition of
said separately added PRMs, in combination with a PMC system to improve the
deposition
and/or release of other PRMs. The PAD and/or AAD system that may be used to
improve also
the deposition of the PMC may be pre-loaded with perfume or added separately
from the
perfume to the product matrix, thus improving both deposition of free PRMs and
PMC, and
optionally modifying the release profile of free perfume and/or encapsulated
perfume from the
situs.
In addition to balancing the overall character and intensity by using
combinations of
TMOT PDTs to delivery different perfumes, perfume accords, or PRMs, another
advantage to
using combinations of TMOT PDTs is to improve the overall deposition and
release profile of
PDTs. For example, cationic polymers and/or other additives may be used to
increase the
CA 02691340 2010-01-27
11249/SK
34
deposition of PMC on the situs. In addition such additives can modify the
release profile of
perfume from PMC. Without being bound by theory, the perfume release may be
modified by
the ability of the additive to increase or decrease the wall porosity or
modify the diffusivity of the
wall to the internal or external phase. Also, without being bound by theory,
the additive may
serve as a perfume sink for PRMs that are released from the PMC either prior
to or after a
triggered release.
In another aspect of the present invention, select PRMs are able to diffuse
through the
wall of the PMC. Such diffusion may be desirable to achieve sustained perfume
release;
however, in other cases the release of such PRMs is considered too fast and
results in a
deficiency of certain PRMs and a change in the preferred character or
intensity. The use of an
additional TMOT PDT, such as a pro-perfume, allows the desired character to be
maintained
over time by providing sustained perfume release, including of those PRMs that
are able to
diffuse through the wall of the PMC. Thus, PRMs that are not effectively
delivered by PMC or
need to be delivered at a different or modified headspace concentration may be
delivered by
means of a TMOT PDT based on pro-perfume technology.
Another aspect of the present invention uses TMOT PDT to enhance the
deposition of
one or more other TMOT PDTs. For example, polymers, preferably cationic
polymers may be
formulated into the product in order to increase the deposition of specific
PRMs and also increase
the deposition of another TMOT PDT, such as a pro-perfume. Such pro-perfumes
include light-
triggered pro-perfumes. The polymer not only serves to increase deposition,
but also serves as a
perfume carrier to deliver additional PRMs to the situs. The polymer may also
serve to modify
the release profile of the PRM or PRMs released from the pro-perfume.
Other examples of improved deposition may be achieved by combining PMC, pro-
perfumes, zeolite or clays, polymer-assisted delivery (e.g., a nanolatex),
amine-assisted delivery,
inorganic nanotubules, photo-pro-perfumes, silicones, and the like.
Another aspect of the present invention allows the formulator to combine TMOT
PDTs to
maximize freshness or minimize scent polarization. Pro-perfume for example may
deliver a
single PRM or even multiple PRMs. Such perfume release may provide a signal as
well as a
preferred character and intensity; however, the release of only a few PRMs can
lead to a less
complex scent character or even a polarizing or unpleasant scent experience.
This issue can be
addressed by balancing the scent character and intensity with PRMs delivered
from other TMOT
PDTs. For example, the use of a perfume microcapsule (PMC) and a pro-perfume
may provide a
scent experience that is superior to either PDT that is used individually.
CA 02691340 2010-01-27
11249/SK
" 5 This invention also includes the use of TMOT PDT combinations to provide
greater scent
intensity and improve scent character at different consumer touch points. For
example, the
TMOT PDT combination may provide desirable scent soon after the situs is dry,
and also at
much later time points. The problem with trying to address the need for
sustained perfume
release over long time periods is that too much perfume may be needed to
achieve the desired
10 results. This is especially the case if the PRMs are volatile and dissipate
too quickly or have a
high odor detection threshold (ODT) and have to be used at levels that are not
practical given the
theoretical perfume loading limits of the PDT. This need is addressed through
the use of TMOT
PDT combinations in which perfume release is triggered at different time
points. For example, a
polymer-assisted delivery TMOT PDT may provide scent shortly after the situs
is dry, and an
15 enzyme-triggered pro-perfume may release perfume from clothes that are
stored in a hamper
waiting to be laundered. The use of PDT combinations also allows the
formulator to hide or
suppress portions of the perfume until the release of said perfume components
are most needed to
provide desired intensity and/or character. Leveraging effective triggers for
timed perfume
release is one means to achieve this goal, in which the headspace of some PRMs
carried by one
20 of the TMOT PDTs is suppressed, until release is initiated by the desired
trigger.
Another example of a combination of two or more TMOT PDTs includes a starch-
coated
perfume-loaded zeolite (PLZ), which may deposit on the situs and begin
releasing perfume from
the situs immediately or soon after the situs is treated with the product; and
a pro-perfume, which
may begin releasing PRMs from the situs when exposed to a release trigger. In
the case of a
25 light-triggered pro-perfume, also known as a photo-pro-perfume, the trigger
is electromagnetic
radiation such as light. Other pro-perfume triggers include water, pH change,
enzymes, or a shift
in an equilibrium due to a change in conditions, for example concentration,
such that perfume is
released at a rate that compliments or enhances the benefits provided by the
other TMOT PDT
used in the PDT combination, such as the perfume-loaded zeolite.
30 Another aspect of the present invention uses one or more PDTs on one situs
and one or
more PDTs on a different situs. For example, the intensity and/or character of
perfume released
from perfume microcapsules on fabric may be enhanced by the perfume released
from the same
or different PDT present on hair or skin, such as another perfume microcapsule
or a pro-perfume.
In another aspect of the present invention, any of the above perfume delivery
technologies
35 (PDTs) may be used to encapsulate or coat any other of the above perfume
delivery technologies.
Such encapsulation or coating may serve to enhance the stability of the
encapsulated or coated
perfume or PDT, or serve to alter the deposition or perfume release profile of
either the
CA 02691340 2010-01-27
11249/SK
36
encapsulated or encapsulating PDT. For examples, a core-shell encapsulation
technology may be
used to encapsulate a pro-perfume with or without additional encapsulated free
perfume. In
another example, a cyclodextrin molecule or a perfume-loaded cyclodextrin may
be encapsulated
by a polymer-assisted delivery system in the form of a matrix or reservoir
system. Perfume-
loaded inorganic zeolites and/or nanotubules may be encapsulated with a
polymer matrix or
polymer shell. In yet another example, a mixture of perfume and silicone is
encapsulated by a
melamine-formaldehyde-based polymer system, or a perfume-loaded melamine-
formaldehyde-
based polymer system is coated with a silicone and/or a perfume-containing
silicone. In still
another example, a PAD is coated with a PAD, for example, as described in USP
5,188,753.
In another aspect of the present invention, a hot melt may be loaded with or
used to coat
or encapsulate any of the above perfume delivery technologies (PDTs). Such PDT
combinations
are particular useful for enhancing the consumer experience at the FMOT.

EXAMPLE #8
In one aspect of the present invention, the perfume delivery system is
particular useful for heavy
duty liquid detergents and/or fabric enhancers. The perfume delivery system
consists of:
1) PAD Matrix System and/or AAD System in the form of a cationic, anionic or
nonionic polymer.
2) PAD Reservoir System in the form of a Perfume Microcapsule (PMC)
3) optional free perfume
Without being bound by theory, a perfume delivery technology (PDT) comprising
a PAD matrix
system and/or an AAD system or systems functions by interacting with perfume
to alter the
stability, deposition and release of the perfume at the FMOT, SMOT and TMOT. A
perfume
microcapsule (PMC) also interacts with perfume to alter the stability,
deposition and release of
the perfume at the FMOT, SMOT and TMOT. Surprisingly, a particularly
synergistic benefit is
observed when one or more PAD matrix system and/or one or more AAD system is
combined
with one or more PAD reservoir system in the form of a perfume microcapsule
(PMC); the
CA 02691340 2010-01-27
11249/SK
49
benefit is greater than the benefit observed for either PDT separately or the
expected combination
of the benefits. In one aspect of the present invention, the PMC may be pre-
loaded with perfume,
and the polymer of the PAD matrix system may be pre-loaded with perfume or
added separately
from the perfume to the product. Without being bound by theory, the
combination of a PAD
matrix system and/or an AAD system with a perfume microcapsule serves one or
more functions.
One function is that the PAD and/or the AAD PDT(s) increase the deposition of
the PMC. A
second function is that PAD and/or AAD serve to "scavenge" perfume that may be
available due
to the presence of the PMC. Without being bound by theory, some perfume may
"leak" out of
the PMC during any stage of the PMC life cycle, which includes manufacturing,
processing,
purifying, isolating, shipping, formulating with other ingredients or during
storage in the delivery
system or product. Without being bound by theory, the PAD and/or AAD PDT is
especially
effective at improving the delivery of certain PRMs, especially those PRMs
with a CLogP less
than about 3 and/or those PRMs with a Kovats Index (KI) value less than 1500.
Some PRMs
may not be effectively held within the PMC, especially during product storage
and at high
temperature; and such PRMs may be delivered more effectively by combining PMC
with PAD
and/or AAD PDTs. As such, one may tune the perfume diffusion stability,
perfume and PDT
situs deposition and perfume release profiles by combining PMC with PAD and/or
AAD PDTs to
achieve a perfume intensity and character at the FMOT, SMOT and TMOT that may
not be
achieved without the PDT combination provided. Without being bound by theory,
such PRMs
are not delivered as effectively when combined with PAD and/or AAD PDTs in the
absence of
PMC because some of these PRMs are high impact and may have low odor detection
thresholds
(ODTs). It is therefore typically necessary to use the PMC to suppress the
level of free perfume
present in the product so that the perfume does not distort the consumer
experience at the FMOT.
Other PRMs have limited stability during product storage, and thus without
being bound by
theory, the PAD and/or AAD PDTs serve to minimize further PRM degradation by
interacting
with those PRMs that are added as free perfume or that may have leaked or
diffused out of the
PMC or other perfume delivery system(s) over time.
EXAMPLE #9
In another aspect of the present invention, the perfume delivery system is
particular useful for
heavy duty liquid detergents and/or fabric enhancers. The perfume delivery
system consists of:
1) PAD Matrix System and/or AAD System in the form of a cationic, anionic or
nonionic polymer.

5 2) PAD Reservoir System in the fonn of a Perfume Microcapsule (PMC)
3) optional free perfume
4) FMOT PDT "on or in the product or package"
FMOT PDT: Without being bound by theory, FMOT PDT such as PAD Hot Melt and/or
PAD
Perfumed Plastic functions by perfume interacting with a perfume carrier, such
as a polymer, to
10 alter the perfume chemical stability and perfume release rate to provide a
consumer desired
intensity and character. Surprisingly, a particularly synergistic benefit is
observed when the
FMOT PDT is used in combination with PAD and/or AAD PDTs and/or PMC,
preferably also
with free perfume. Without being bound by theory, the PDT combination serves
to mitigate
scent character distortion that can occur from the interaction of PAD and/or
AAD PDTs and/or
15 PMC with pre-loaded or separately added perfume. With the use of the FMOT
PDT, the
combination of perfume with PAD and/or AAD and/or PMC PDTs may be optimized in
order to
provide the greatest consumer benefit during the SMOT and TMOT. It can be
difficult for the
formulator of perfume and PDTs to achieve the ideal scent intensity and
character at all
consumer touch points. The use of FMOT PDT surprisingly reduces the impact of
the
20 formulated perfume and PDTs on the FMOT experience, such as neat product
odor. As such,
this minimizes some constraints around perfume formulation and allows the
formulator to
optimize the PAD and/or AAD and/or PMC PDTs especially for greatest TMOT
impact. The
distortion in neat product odor that may be needed to maximize TMOT benefit is
diminished by
this PDT combination. In particularly, the need for FMOT PDT is surprisingly
greatest when
25 used in conjunction with the combination of PAD and/or AAD and/or PMC PDTs,
due to the
unexpected decrease in neat product intensity and change of character
associated with the
unexpected perfume interactions described above, which is mitigated by the
FMOT PDT.
EXAMPLE #10
30 In one aspect of the present invention, the perfume delivery system is
particular useful for heavy
duty liquid detergents and/or fabric enhancers. In another aspect, the perfume
delivery system
consists of:
1) (optional) Cationic polymer (PAD and/or AAD)
2) PMC based on urea or melamine formaldehyde
35 3) Free perfume
4) (optional) Hot melt or perfumed plastic insert on or under the product cap
or lid

EXAMPLE #11
In one aspect of the present invention, the perfume delivery system is
particular useful for heavy
duty liquid detergents and/or fabric enhancers. In another aspect, the perfume
delivery system
consists of:
1) (optional) Cationic polymer (PAD and/or AAD)
2) PMC based on urea or melamine formaldehyde
3) Free perfume
4) (optional) Hot melt or perfumed plastic insert on or under the product cap
or lid
5) Photo-Pro-Perfume (PPP)
Without being bound by theory, PPP, PMC, PAD, AAD and APAD PDTs interact with
perfume
to alter the stability, deposition and release of the perfume at the FMOT,
SMOT and TMOT.
Surprisingly, a particularly synergistic benefit is observed when PPPs are
combined with PMC
and/or PAD and/or AAD PDT(s). In particular, the PPP PDT can be selected such
that PRM
release from the situs is complimentary to that observed for PMC and/or PAD
and/or AAD
PDTs. In particularly, although PMC and/or PAD and/or AAD PDTs are effective
at delivering a
broad range of PRMs to the situs, in some cases, having certain PRMs present
on the situs at too
low a concentration or releasing into the headspace above the situs at too
slow a rate will lead to
a distortion of the desired intensity and character. This can especially be
the case after longer
time periods since situs drying. We have surprisingly found that the character
and/or intensity
can be maintained for longer period of time when PPP is used in combination
with PMC and/or
PAD PDTs. In addition, the PMC and PAD and/or AAD PDTs can increase the
deposition of the
PPP PDT. Also without being bound by theory, the PMC and/or PAD and/or AAD
PDTs can
alter the release profile from the dry situs of the perfume from the PPP.
Without being bound by
theory, this unexpected result may be due to the other PDTs altering the
interaction of the PPP
and the released PRMs from the dry situs, thus altering perfume release
properties.
EXAMPLE #12
In one aspect of the present invention, the perfume delivery system is
particular useful for
Laundry Granules. In another aspect, the perfume delivery system consists of:
1) SEA; and
2) PMC; and
3) (optional) Spray on perfume; and
4) (optional) FMOT PDT "on or in the product or package"
CA 02691340 2010-01-27
. 11249/SK
52
Without being bound by theory, it has been surprisingly found that there is a
symbiotic effect of
using the combination of SEA and PMC. Both PDTs provide improved retention of
volatile
perfume prior to consumer use; however, the different release profiles for SEA
and PMC enable
a release system that is superior to using either PDT separately. The release
of perfume from
SEA upon use of product is relatively fast, whereas the release from PMC is
relatively slow.
lo This combination of bloom and triggered release from dry situs provide
benefit throughout the
use experience.
EXAMPLE #13
In one aspect of the present invention, the perfume delivery system is
particular useful for
Laundry Granules. In another aspect, the perfume delivery system consists of:
1) PLZ and/or PLT; and
2) PMC; and
3) (optional) Spray on perfume; and
4) (optional) FMOT PDT "on or in the product or package"
5) (optional) SEA
Without being bound by theory, it has been surprisingly found that there is a
symbiotic effect of
using the combination of PLZ and/or PLT and PMC. Both PDTs provide improved
retention of
volatile perfume prior to consumer use; however, the different release
profiles for SEA and PMC,
particularly from dry situs, provide a release system that is unexpectedly
superior to using either
PDT separately. Without wishing to be bound by theory, the perfume release
profiles for PLZ
and/or PLT and PMC is different. For PLZ, the release is triggered by removal
of a water-
soluble coating to initiate perfume diffusion into the headspace of the dry
situs. For PLT, the
release is triggered by removal of any end-capping groups and diffusion also
by reverse capillary
action. For PMC, the release can also be triggered by the removal of an
optional water-soluble
coating, and/or by diffusion into the headspace of the dry situs. Each PDT has
been optimized to
deliver perfume accords that work best with the technology. For PLZ, PRM
selection is also
made based on molecular size. For PLT, PRM selection is based on a number of
factors
including volatility, odor detection threshold, size and Kovats Index (KI)
value. For PMC the
selection includes considerations of wall permeability or leakage. Thus, a
combination of these
PDTs allows for a fuller palette of PRMs to achieve the desired intensity and
character. In
addition to the perfume diffusion release mechanism, the PMC can be selected
to provide a
friction-triggered release or burst of perfume, leading to greater perfume
intensity and a preferred
CA 02691340 2010-01-27
11249/SK
53
character. Such a combination of perfume diffusion of preferred PRMs and a
burst of perfume
due to alternate release mechanism provides unexpectedly improved benefits
over what would be
expected.
EXAMPLE #14
In one aspect of the present invention, the perfume delivery system is
particular useful for
Laundry Granules. In another aspect, the perfume delivery system consists of:
1) PDT selected from PLZ, SEA, CD, PMC
2) (optional) Spray on perfume; and
3) FMOT PDT "on or in the product or package"
Laundry granules are difficult to smell because of closed container. FMOT PDT
on the outside
of the product or package provides FMOT scent intensity and character. In
another aspect, the
presence of the FMOT PDT on the inside of the package provides unexpected
synergies with
other PDTs.

EXAMPLE #17
In one aspect of the present invention, the perfume delivery system is
particular useful for a
Fabric Softener. In another aspect, the perfume delivery system consists of:
1) Hexarose (geranyl palmitate) 0.25%; and
2) Perfume Microcapsule (PMC) 1.3%; and
3) (optional) neat perfume 0.6%; and
4) (optional) FMOT PDT "on or in the product or package"
5) (optional) SEA
All percentages listed in this Example 17 are based on total product weight
independent of any
container and/or packaging.
The weight percentages of the aforementioned ingredients may be varied as
desired, for example,
the hexarose (also known as (E)-3,7-dimethyl-2,6-octadienylhexadecanoate) may
be present at
levels of from about 0.05% to about 10%, from about 0.1% to about 1%, or even
from about
0.25% to about 0.75%; the PMC may be present at levels of from about 0.05% to
about 10%,
from about 0.1 % to about 3%, or even from about 0.3% to about 1.5%; and the
neat perfume may
be present at levels of from about 0.01% to about 10%, from about 0.1% to
about 3%, or even
from about 0.5% to about 1.5%. The aforementioned perfume delivery system may
be used in
other consumer products, including other cleaning and/or treatment products,
for example such
products that contain minimal or no lipase. In addition, other terpene esters
may be substituted
for hexarose or even beta-keto esters may be used. Suitable terpene esters may
be produced in
accordance with the teachings of USP 5,652,205. For example, hexarose may be
made by
following the teachings of Example I of USP 5,625,205 and replacing the
succinic acid with
palmitic acid or Example II of USP 5,652,205 and replacing lauroyl chloride
with palmitoyl
chloride. Suitable beta-keto esters may be made in accordance with the
teachings of USPs
6,100,233 and 5,965,767.
