PERFUMING METHOD AND PRODUCT
Background of the Invention
Fabric enhancers are well-known as a distinct consumer product category which
has unique
challenges associated with formulation and packaging. Such products commonly
contain perfume,
and are sold in packages such as bottles, from which the product is poured
through a relatively wide-
necked pouring spout. Consumers generally desire a clean and fresh odor
whenever they open the
package and smell the product, after the completing of the washing and/or
drying cycles, and on
laundered clothing that has been stored for a period of time.
Perfumed fabric enhancers continue to have many shortcomings. For example,
perfumes are
complex mixtures of costly ingredients and are often chemically reactive or
incompatible with fabric
enhancers. This can adversely affect both the perfumes and the materials with
which they interact.
Further, these compatibility problems can be much greater than those
encountered in the case of
technically simpler cleaning products such as toilet bowl cleaners, automatic
dishwashing products,
shampoos or dishwashing agents. Shampoos and hand dishwashing products, in
particular, are sold
in packages having restricted orifices through which the products are
squeezed, and therefore do not
have a large opening through which a consumer can smell the product.
Fabric enhancer ingredients may contain certain components with undesirable
odor and
further, fabric enhancers contain a challenging array of adjuncts that make
perfume stabilization
difficult. Moreover a major fraction of the costly perfumes can be lost "down
the drain" when the
product is used to treat clothes in an automatic laundry washing machine.
Additionally, the scent of
the perfume on the washed or treated substrate should be long lasting.
Finally, the fabric enhancer
must have an overall perfume character that is acceptable to consumers.
What is therefore needed are fabric enhancers that provide improved perfume
impression on
opening the package, improved efficiency of use of perfumery ingredients,
better compatibility of
perfume and fabric enhancer, better perfume impression at various points
during use of the product
and on the laundered textiles thereafter, the ability to incorporate a range
of modern performance
adjuncts, and the ability to effectively control any malodor of commonly
available fabric enhancer
materials.

10747/JC 2
These needs must be met in a manner consistent with satisfying consumers with
respect to
the olfactory character of perfumes that they seek in the specific context of
fabric laundering, and
without incurring manufacturing complexity increase as the components of
package and fabric
enhancer are assembled into the product that is to be sold.
Summary of the Invention
In one aspect, the present invention includes a fabric enhancer product
comprising (a) a
package comprising (1) a container; and (2) a closure; (b) a fabric enhancer
comprising a material
copourable from the package with the fabric enhancer, wherein the material is
selected from: (1) a
fabric enhancer-copourable perfume composition; (2) a fabric care additive;
and (3) any combination
thereof; (c) a headspace; and (d) a fabric enhancer-non-copourable perfume
composition;
wherein the pH of the fabric enhancer is less than about 7.
Detailed Description of the Invention
One aspect of the invention relates to a fabric enhancer product comprising
(a) a package
comprising (1) a container; and (2) a closure; (b) a fabric enhancer
comprising at least one fabric
care additive and a material copourable from the package with the fabric
enhancer, wherein the
material is selected from: (1) a fabric enhancer-copourable perfume
composition; (2) a fabric care
additive; (3) perfume microcapsules; and (4) any combination thereof; (c) a
headspace; and (d) a
fabric enhancer-non-copourable perfume composition.
Without wishing to be bound by theory, it is believed that the present
invention delivers
perfume during at least four significant points to the consumer while
maximizing the efficiency of
the perfumes contained within the container. The consumer is presented with
perfume when
opening the container at the first moment of truth. The consumer is presented
with perfume after the
completion of the laundry cycle at the second moment of truth. Finally, the
consumer is presented
with perfume after the storage of clothing, as well as during the wear of
clothing at the third moment
of truth.
There is a need by consumers who desire second and third moment of truth
experience, for
example, scent out of the dryer and dry fabric odor. Some consumers, however,
desire the dry fabric
odor to last up to 1 week, but not much longer. For consumer who want to
control such initial dry
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 3
fabric odor intensity, we have surprisingly found that such a scent experience
can be achieved by
formulating the fabric enhancer with a low, even zero, free or neat perfume
level if the perfume
microcapsule and amine-assisted delivery systems concentrations are selected
such that the
polymeric amine to free perfume ratio is about greater than 0.4 and about less
than 25, even about
greater than 0.4 and less than 5. In another embodiment, such fabric enhancer
compositions also
include a fabric enhancer-non-copourable perfume.
There is also a need by consumers who desire the third moment of truth
experience to last for
longer periods, for example, their dry fabric to have greater scent intensity
for more than 1 week.
For consumer who desire to obtain dry fabric odor intensity for even longer
periods of time, we have
surprisingly found that such a scent experience can be achieved by formulating
the fabric enhancer
with microcapsule and polymeric amine and free perfume. Surprisingly,
increasing polymeric amine
levels much beyond 1% leads to a reduction in dry fabric odor performance.
More surprisingly, it
was discovered that a polymeric amine to free perfume ratio of greater than
0.030 and less than 0.40
results in the desired dry fabric longevity experience.
Without wishing to be bound by theory, the selected ratio of polymeric amine
to free perfume
may provide the proper balance between perfume deposition and perfume release.
Ratios that are
outside the current invention may lead to greater perfume suppression and
untimely release.
It has also been surprisingly found that the ratio of total polymer
concentration, of all
polymers with a molecular weight greater than 1000 Daltons in the fabric
enhancer-copourable
perfume composition, to perfume in the fabric enhancer-copourable perfume
composition is an
important factor for achieving the consumer desired perfume scent longevity.
In one embodiment,
the total polymer to free perfume ratio is from about 0.02 to about 3.0%, in
another embodiment
from about 0.10% to about 2.0%, in another embodiment from about 0.20 to about
1.0%.
Package
One aspect of the invention relates to a fabric enhancer product comprising a
package
comprising (1) a container, typically a bottle, and (2) a closure. In certain
embodiments, the package
further comprises (3) a transition component, such as a transition collar.
Suitable packages may be
found in U.S. 4,550,862, U.S. 5,108,009, U.S. 6,398,076, and U.S. 6,659,310.
In certain
embodiments when the fabric enhancer comprises two or more liquids which are,
for example,
immiscible, it may be advantageous to use a package as described in U.S.
6,644,511.
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 4
In certain embodiments, it may be advantageous to include a vented closure
device. Suitable
vented closure devices are described in U.S. 6,601,740 and 6,874,656.
In certain embodiments, it may be advantageous to include a drain-back snap-on
pour spout
closure to equip the container with child safety features. In certain such
embodiments, the drain
back pour spout fitment has a snap fit structure overlaying a container neck
finish and may be
secured thereto with adhesives. The snap fit structure includes an outer
annular skirt with internal,
radial inwardly facing beads engaging a radial outwardly facing surface of the
container finish.
Spaced from the outer annular skirt by a horizontal upper flange, the spout
fitment includes an inner
annular skirt with internal threads on the fitment to receive an externally
threaded closure. The
closure has a plug seal above the threads engaging the upper flange of the
fitment and a radial
outwardly facing latch engaging a radial inwardly facing interfering
projection on the fitment
forming a child safety feature for the fitment closure. An example of such a
closure may be found in
U.S. 6,923,341.
Any suitable structural plastic may be used to make the packages. Such
structural plastics
include, but are not limited to, polyethylene, polypropylene, polyethylene
terephthalate, and the like.
In certain embodiments, the structural plastic of the package may be
transparent as described in U.S.
6,756,350. In certain alternative embodiments, the structural plastic may be
opaque, or may
incorporate structural plastics having differing opacity, e.g., a transparent
stripe through which the
level of product in the package can be seen, while the remainder of the
package is opaque.
In certain embodiments, it may be advantageous to use a stress crack resistant
bottle.
Suitable examples of such containers can be found in U.S. 6,464,106 and U.S.
6,223,945.
pH
In one embodiment, the fabric enhancer of the present invention has a pH of
about 1 to about
7, in another embodiment from about 2 to about 6.5, in another embodiment from
about 4 to about 6
in another embodiment from about 2 to about, in another embodiment from about
2.5 to about 4. In
one embodiment the pH of the fabric enhancer is less than 7. It is believed
that the acidic nature of
the fabric enhancer aids in imparting a softness feel to the fabric,
particularly when used in the rinse
cycle.

The term "perfume", as used herein, includes any odoriferous material, other
than
malodorous impurities that can be present in technical grades of fabric care
actives, solvents, and
builders. In general, such materials are characterized by a vapor pressure
that is less than the
atmospheric pressure at ambient temperature. The perfumes employed herein will
most often be
liquid at ambient temperatures, but may also be solid such as the various
camphoraceous perfumes
or other sublimable perfumes known in the art. A wide variety of chemicals are
known for
perfumery uses, including materials such as perfumery aldehydes, ketones,
esters, alcohols, terpenes,
and the like. Naturally occurring plant and animal oils and exudates
comprising complex mixtures
of various chemical components are known for use as perfumes, and such
materials can be used
herein. The perfumes herein can be relatively simple in their composition or
can comprise highly
sophisticated, complex mixtures of natural and synthetic chemical perfumery
components, all chosen
to provide any desired odor. In one aspect of this invention, perfumes
comprise at least one perfume
raw material. Perfume raw materials are compositions that can be used in
combination with each
others to create various scents.
Typical perfumes which can be used in the present invention comprise, for
example,
woody/earthy bases containing exotic materials such as sandalwood oil, civet,
patchouli oil and the
like. Other suitable perfumes are for example light, floral fragrances, e.g.,
rose extract, violet extract
and the like. Perfumes can be formulated to provide desirable fruity odors,
e.g., lime, lemon, orange,
and the like.
In short, any chemically compatible material which emanates a pleasant or
otherwise
desirable odor may be used as a perfume. Perfume materials are described more
fully in S.
Arctander, Perfume Flavors and Chemicals. Vols. I and II. Author, Montclair,
N.J., and the Merck
Index, 13th Edition, Merck & Co., Inc. Rahway, N.J.
The terms "malodor" and "malodorous", as used herein include, but are not
limited to,
enzyme derived, short-chain fatty acids, or nitrogenous compounds such as
amines, polyamines,
amine oxide surfactants, amides, alkanolamines, ammonia, or ammonium-
containing moieties.
In certain embodiments, perfumes for use herein can be encapsulated or
microencapsulated.
Encapsulated perfume may be dispersed throughout the polymeric material of the
fabric enhancer-
non-copourable perfume composition. Perfumes for use herein can also be added
as neat perfume.
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 6
Neat perfumes are not encapsulated or microencapsulated. Rather, neat perfumes
are typically
liquids or solids that are to the fabric enhancer.
Alternatively, one or more perfumery compounds which are incorporated in a
fabric enhancer-
copourable perfume composition may be encapsulated. In one embodiment the
encapsulated
perfumery compounds that are in the fabric enhancer-copourable composition are
absent from the
fabric enhancer-copourable perfume composition. In certain embodiments fabric
enhancer-
copourable perfume compositions may be encapsulated while the fabric enhancer-
non-copourable
perfume itself is dispersed throughout a polymeric material such as a low-
melting thermoplastic, e.g.,
a hot-melt adhesive; optionally in combination with conventional plasticizers
and/or tackifiers.
As used herein, "encapsulation" is art-recognized and refers to the formation
of a shell which
completely surrounds a small amount of the perfume. The shell material may be
identical to a
polymer composition of the fabric enhancer-non-copourable perfume, or may
comprise any other
ingredient that do not detract from the polymer composition properties both
prior to and after
rupturing of the shell to release the perfume. Similarly, the perfume may be
encapsulated in a shell
that itself, along with other capsules, is encapsulated. In another
embodiment, the capsule shell wall
material comprises organic polymers such as gelatin, urea-formaldehyde,
polyurethane, melamine-
formaldehyde, or combinations thereof.
In certain embodiments, the fabric enhancer-copourable perfume composition has
an olfactory
character that matches that of the fabric enhancer-non-copourable perfume
composition. In certain
alternative embodiments, the fabric enhancer-copourable perfume composition
has an olfactory
character that is different from that of the fabric enhancer-non-copourable
perfume composition.
Perfumes are typically composed of many components of different volatility.
The fabric
enhancer-non-copourable perfume composition, in one embodiment, avoids
separation of the
components based on their different volatility and allows the sustained
delivery of the full perfume
bouquet for a long time. In certain preferred embodiments, the perfume is a
perfume which is, in
one embodiment, composed by a plurality of components, in one embodiment by
more than 5
components.

Fabric enhancer-non-copourable Perfume Composition
The fabric enhancer product comprises a fabric enhancer-non-copourable perfume
composition. Suitable fabric enhancer-non-copourable perfume compositions for
use herein include
the polymeric compositions for sustained release of volatile materials
described in WO 2005/049717
A2. Over and above any perfumes or malodors which can enter the headspace by
volatilization from
the fabric enhancer (when such materials are present therein), the fabric
enhancer-non-copourable
perfume composition provides an effective technology for diffusing a perfume
throughout the
headspace. In one embodiment, the polymeric composition associated with the
fabric enhancer-non-
copourable perfume composition for sustained release is considered a polymer
assisted delivery
(PAD) matrix system.
In certain embodiments, the release of perfume from the fabric enhancer-non-
copourable
perfume composition is passive.
The term "passive" as used herein is meant to include routes of release of the
perfume
composition, such as by diffusion, which does not require intervention by the
user. In contrast,
"active" routes of release require action by the user, including, but not
limited to, squeezing of a
perfume from a suitable medium, such as a sponge, or by a twisting action, to
release the perfume
composition. In passive release, in one embodiment, even when subjected to
closure or shaking of
the package, the rate of release of the perfume composition remains unchanged,
i.e., rapid and/or
intermittent release of the perfume composition is not the primary mechanism
of release.
In certain embodiments, the fabric enhancer-non-copourable composition is
affixed to an
internal portion of the package, provided that when the fabric enhancer-non-
copourable perfume
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 24
composition is meltable, the fabric enhancer-non-copourable perfume
composition has a pouring
temperature of at least about 5 C, at least about 10 C, or even at least
about 15 C above the
ambient storage temperature.
The fabric enhancer-non-copourable perfume composition may be located in the
container,
the transition component, the closure, or any combination thereof. The fabric
enhancer-non-
copourable perfume composition may be formed into any of various shapes
including rings, annular
disks, circles, squares, rectangle, or any other shape that is suited to the
shape of the space of in
which the fabric enhancer-non-copourable perfume composition is to be
incorporated. In certain
embodiments, the fabric enhancer-non-copourable perfume composition is located
in the transition
component of the package, or into an element forming a self-draining
dispensing orifice rather than
in a cap or closure.
In certain embodiments, the fabric enhancer-non-copourable perfume composition
is
adsorbed onto or affixed to a solid having dimensions larger than the outlet
of the package and
floatable in the fabric enhancer; provided that when the perfume composition
is meltable, the
pouring temperature thereof is at least 5 C above the ambient storage
temperature. In certain such
embodiments, the fabric enhancer-non-copourable perfume composition is in the
form of a hollow
sphere, however, the fabric enhancer-non-copourable perfume composition may be
in any suitable
shape, either hollow or solid, including, but not limited to, a sheet, star,
flower, disk, rectangle,
square, or any other shape, provided that the fabric enhancer-non-copourable
perfume composition is
dimensioned such that it is larger than the outlet of the package and provided
that it is floatable in
the fabric enhancer. In certain embodiments, it may be advantageous for the
package to be
transparent and for the fabric enhancer-non-copourable perfume composition to
be any one of a
number of shapes and/or colors. In certain embodiments, the fabric enhancer-
non-copourable
perfume composition may have more than one color. In certain embodiments, the
package may
contain more than one fabric enhancer-non-copourable perfume composition.
Moreover, the fabric
enhancer-non-copourable perfume composition may be directly or indirectly
affixed to a component
of the package. For example, an indirect affixing method involves having a
perfumed hot-melt
adhesive set upon a thin plastic film, e.g., of HDPE, which is in turn bonded
to a packaging element
by means of a separate adhesive material such as an adhesive tape. Thus, the
stickiness of the fabric
enhancer-non-copourable perfume composition is not always critical.
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 25
In certain embodiments, the fabric enhancer-non-copourable perfume composition
comprises
a perfume and a polymeric composition, in one embodiment the fabric enhancer-
non-copourable
perfume composition has the ability to release the perfume in a sustained
manner, i.e. with a
relatively constant release rate and for a long period of time, such that
there is still a detectable
amount of perfume in the fabric enhancer-non-copourable perfume composition
when the fabric
enhancer has been used or only a residual amount of the fabric enhancer
remains in the container. In
certain preferred such embodiments, release of the perfume of the fabric
enhancer-non-copourable
perfume composition is substantially unchanged even when repeatedly contacted
with the fabric
enhancer. In other words, the fabric enhancer does not itself extract the
perfume from the fabric
enhancer-non-copourable perfume composition.
Unless otherwise specifically indicated, the phrase "polymeric composition"
herein refers to
a thermoplastic polymeric composition that can be used to deliver the perfumes
in the fabric
enhancer-non-copourable perfume composition. The term "polymeric composition"
as used herein
differs from packaging plastics. In one embodiment, a "polymeric composition"
has a softening
temperature at least about 10 C below that of packaging plastics used for
bottle making, but remains
non-pourable at temperatures of at least about 35 C in the absence of added
perfume.
In certain embodiments, the perfume of the fabric enhancer-non-copourable
perfume
composition is released by diffusion into the headspace. In certain such
embodiments, the fabric
enhancer-non-copourable perfume composition may optionally be separated from
the fabric
enhancer by a permeable liner element, though such an element is not
essential. In certain such
embodiments, the liner is permeable to the perfume materials, but impermeable
to the fabric
enhancer. In general, the fabric enhancer-non-copourable perfume composition
can be allowed to
come into contact with the fabric enhancer.
In general, proportions by weight of fabric enhancer-non-copourable perfume
composition to
fabric enhancer can vary widely, e.g., from about 0.01 grams to about 2 grams,
in another
embodiment from about 0.05 grams to about 1 gram, in another embodiment from
about 0.1 grams to
about 0.8 grams of fabric enhancer-non-copourable perfume composition are
sufficient for
perfuming products comprising up to about 3 kg of fabric enhancer.
In certain embodiments, the fabric enhancer-non-copourable perfume composition
comprises
from about 1 wt % to about 80 wt% of perfume, in one embodiment from about 10
wt % to about 60
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 26
wt%. In certain such embodiments, the balance of the fabric enhancer-non-
copourable composition
comprises thermoplastic polymers, plasticizers, tackifiers, or any combination
thereof.
When the product as a whole comprises both a fabric enhancer-non-copourable
perfume
composition and a fabric enhancer-copourable perfume composition, the weight
ratio of perfume in
the fabric enhancer-copourable composition to perfume in the fabric enhancer-
non-copourable
perfume composition is from about 0:1 to about 1:0.
When the product as a whole comprises both a fabric enhancer-non-copourable
perfume
composition and a fabric enhancer-copourable perfume composition and the sum
of these is taken as
100% of all perfume in the product, then an effective amount of fabric
enhancer-non-copourable
perfume composition may be as low as about 0.001 wt%, more typically from
about 0.01 to about 3
wt% (i.e., up to three hundredths by weight) of all perfume in the product.
In another embodiment, the fabric enhancer can be unperfumed and a suitable
amount of fabric
enhancer-non-copourable composition will comprise 100 wt% of all perfume.
In a particularly preferred embodiment, the fabric enhancer-copourable perfume
composition
may comprise up to about 0.1%, in one embodiment up to about 50%, in one
embodiment up to
about 100% of fabric substantive perfume raw materials.
In certain embodiments, it may be advantageous to minimize the amount of
fabric enhancer-
copourable perfume which may be susceptible to interaction with other fabric
enhancer ingredients,
for example by having a level of fabric enhancer-copourable perfumes of less
than about 20%, less
than about 10%, or even less than about 1% of the total of perfume in the
product. In certain such
embodiments, it may be advantageous to encapsulate the fabric enhancer-
copourable perfumes in a
polyamine shell.
Suitable polymeric compositions are capable of effectively delivering a wide
variety of
perfumes in a broad polarity range, and also adhere well to plastic packaging
construction materials
such as high density polyethylene, polyethylene terephthalate, polypropylene
and the like. Suitable
polymeric compositions may further comprise additives which allow the tuning
of its polarity
characteristics very precisely. This makes it possible to maximize the
compatibility with any
perfume which could be introduced in the plasticized polymeric matrix thus
obtaining a polymeric
composition according to the present invention. Without being bound by theory,
it is believed that a
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 27
certain polarity match between the plasticized polymeric matrix and the
perfume is required to
provide good incorporation and sustained delivery of the perfume.
In certain embodiments, the polymeric composition may be formed into a
material selected
from a film, a sheet, a foam, or an adhesive. In certain embodiments, the
polymeric composition is
formed into an adhesive, in one embodiment a solidified hot-melt adhesive.
In certain embodiments, the fabric enhancer-non-copourable perfume composition
is a
solidified hot-melt adhesive that further comprises at least one plasticizer,
at least one tackifier, or
any combination thereof.
In certain embodiments, the fabric enhancer-non-copourable perfume composition
is insoluble
in the fabric enhancer.
The fabric enhancer-non-copourable perfume composition may be affixed to the
package using
any suitable method. In certain such embodiments, the surface of the package
to which the fabric
enhancer-non-copourable perfume composition is affixed is first subjected to
localized roughing.
Methods for such localized roughing are well known in the art, e.g., by
abrasion of an otherwise
smooth packaging plastic.
In certain embodiments, suitable polymeric compositions can be formulated as
hot-melt
adhesives that have a low application temperature, in one embodiment below
about 100 C and in
some cases below about 70 C. This is a particularly desirable property for
materials used to
incorporate perfumes as the higher is the processing temperature, the greater
is the risk of losing by
evaporation significant amounts of the perfume incorporated during the
manufacturing of the
composition. Moreover, higher application or processing temperatures may
increase safety hazards
associated with processing of the polymeric compositions. Examples of suitable
hot-melt adhesives
may be found in U.S. 6,084,010 and U.S. 5,827,913.
The solidified perfumed hot-melt adhesive may be produced by processing a
thermoplastic
resin with perfumes to form a homogeneous mixture at process temperatures less
than about 85 C.
In certain such embodiments, the thermoplastic resin is added to a fluid
comprising perfume.
Accordingly, a method for producing a solidified perfumed hot-melt adhesive
comprises processing
a thermoplastic resin with perfumes to form a homogeneous mixture at process
temperatures less
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 28
than about 85 C. In certain embodiments, the method comprises processing the
thermoplastic resin
by adding it to a fluid comprising perfume.
In certain embodiments, the polymeric composition comprises a) a copolymer of
ethylene
with at least another monomer comprising at least one heteroatom; and b) more
than 10% of a
plasticizer comprising at least a heteroatom. Such compositions may be formed
into films, sheets,
foams, and adhesives, or hot-melt adhesives. These hot-melt adhesive
compositions have good
adhesion on most substrates (plastic films, foams, cardboard, and the like).
Suitable copolymers may be block or non-block copolymers, grafted copolymers,
copolymers
with side chains, or crosslinks, or copolymers where ethylene monomers are
randomly
copolymerized with monomers comprising at least one heteroatom.
Suitable copolymers of ethylene are, for example, ethylene-vinyl ester
copolymers, ethylene-
acrylic ester copolymers, ethylene-methacrylic ester copolymers, ethylene-
acrylic acid copolymers
and their salts, ethylene-methacrylic acid copolymers and their salts,
ethylene-vinyl ester-acrylic
acid copolymers, ethylene-vinyl ester-methacrylic acid copolymers, ethylene-
vinyl ester-maleic
anhydride copolymers, ethylene-acrylic ester-maleic anhydride copolymers,
ethylene-vinyl ester-
glycidyl methacrylate copolymers, ethylene-acrylic ester-glycidyl methacrylate
copolymers,
ethylene-maleic anhydride copolymers, ethylene-glycidyl methacrylate
copolymers.
The monomer comprising at least one heteroatom in the copolymers in one
embodiment
represents from 10% to 90% of the total weight of the copolymer, in one
embodiment at least 14% in
one embodiment at least 18%.
Particularly preferred copolymers are ethylene-vinyl acetate copolymers such
as those sold
under the trade names E1vaxTM by Dupont, EvathaneTM by Atofina, EscoreneTM by
Exxon and
LevaprenTM and LevameltTM by Bayer and ethylene-acrylic ester copolymers such
as those sold
under the trade name LotrylTM by Atofina.
The term "monomer comprising at least a heteroatom" includes all those
monomers which
comprise at least a C-X linkage in the molecule wherein X is not C or H. Said
C-X linkage is in one
embodiment a polar linkage. In one embodiment the carbon atom is linked to an
N, S, F, Cl, or 0
atom. In one embodiment said polar linkage is part of a carbonyl group and, in
one embodiment,
said polar linkage is part of an ester group. Preferred monomers comprising at
least a heteroatom for
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 29
the present invention are vinyl acetate, vinyl alcohol, methyl acrylate, ethyl
acrylate, butyl acrylate,
acrylic acid and salts formed therefrom, methacrylic acid and salts formed
therefrom, maleic
anhydride, glycidyl methacrylate and carbon monoxide.
A second component for the polymeric compositions of the present invention is
a plasticizer or
blend of plasticizers comprising at least one heteroatom, which plasticizer or
blend of plasticizers is
compatible with the copolymer of ethylene with at least another monomer
comprising at least a
heteroatom. The term "plasticizer comprising at least a heteroatom" includes
all those plasticizers
which comprise at least a C-X linkage in the molecule wherein X is not C or H.
Said C-X linkage is
in one embodiment a polar linkage. In one embodiment the carbon atom is linked
to an N, S, F, Cl,
or 0 atom. In one embodiment said polar linkage is part of a carbonyl group
and, in one
embodiment, said polar linkage is part of an ester group.
Suitable plasticizers for use in the polymeric compositions according to the
present invention
are described in WO 2005/049717 A2 incorporated herein by reference in its
entirety and include
citric acid esters, low molecular weight polyesters, polyethers, liquid rosin
esters, aromatic
sulfonamides, phthalates, benzoates, sucrose esters, derivatives of
polyfunctional alcohols (where
polyfunctional means having 2 or more hydroxyl groups), adipates, tartrates,
sebacates, esters of
phosphoric acid, fatty acids and diacids, fatty alcohols and diols, epoxidized
vegetable oils etc and
mixtures thereof. As already mentioned above, the different polarity of the
different compatible
plasticizers (measurable with any method known to those skilled in the art,
for example
water/octanol partition coefficient) can be used to tune the polarity of the
polymeric matrix in order
to provide a better match with the polarity of the perfume.
The polymeric compositions of the present invention in one embodiment are
thermoplastic
polymeric compositions. These can be manufactured by using any known process
for manufacturing
thermoplastic polymeric compositions and will typically comprise melting the
polymer and then
homogeneously blending the plasticizer and the perfume to form a homogeneous
mass that is then
cooled to obtain the polymeric composition. Among thermoplastic compositions
preferred are those
which have low melt temperature and viscosity and therefore may be processed
as hot melts. In
these hot-melt systems, the loss of perfume upon blending, as well as upon
subsequent application in
the molten state, is minimized.
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 30
Other optional components which can be used when the polymeric composition
according to
the present invention is a thermoplastic composition and is suitable for use
as a perfumed hot-melt
adhesive, are tackifying resins such as rosin derivatives, aliphatic resins,
aromatic resins or mixed
aliphatic-aromatic resins in order to further increase the adhesion capacity
of the compositions of the
present invention. Further optional ingredients such as other polymers or
copolymers, fillers,
crosslinkers, pigments, dyes, antioxidants and other stabilizers, etc can also
be added to provide
desired properties to the composition.
The polymeric compositions may also be prepared using a polymer solution,
either as an
intermediate or final step. Preparations of this type are well known to those
skilled in the art and
typically will comprise the steps of dissolving the selected polymer,
plasticizer, and perfume in an
effective solvent, and heating if necessary to prepare a solution or a gel.
The solvent can then be
eliminated by evaporation, thereby providing the polymer composition
containing the perfume
dispersed therein.
Alternatively, the polymeric compositions may be prepared in the form of an
aqueous
emulsion or dispersion. The techniques for obtaining aqueous emulsions or
dispersions of polymers
are well known to one of skill in the art. For example, the selected polymer,
plasticizer, and perfume
can be blended together as a thermoplastic material. The resulting melt can
then be dispersed in
water, at a temperature above its melting point, by mixing and surfactant
and/or stabilizing systems
known to those skilled in the art can be employed to stabilize the resultant
emulsion or dispersion.
In certain alternative embodiments, a preformed aqueous polymeric dispersion
or emulsion can
be blended with the selected plasticizer and perfume. This can be accomplished
by adding the
ingredients directly to the polymeric dispersion or emulsion, or e.g. by
forming an aqueous
dispersion of the perfume and plasticizer and blending this with the polymeric
dispersion or
emulsion. Both procedures result in the formation of an aqueous dispersion of
a polymeric
composition. Water can be then eliminated by evaporation.
Alternatively, the copolymer can be directly formed in a water dispersion in
the presence of
the plasticizer and/or of the perfume. This process may involve the solution
or dispersion of
monomers or prepolymers in water that contains the dispersed perfume and/or
plasticizer followed
by initiation to form the polymeric dispersion. If required, the perfume or
plasticizer can be
alternatively added subsequently to produce a dispersed polymeric composition.
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 31
The polymeric compositions due to their rheology and their adhesion properties
are
particularly useful to be applied in the molten state onto a selected
substrate, and directly adhered
thereto. They can be applied, for example, to the inner surface of a container
in a suitable position in
order to suitably modify the headspace in the container by releasing the
perfume to create a
perfumed headspace. Such release is "passive", i.e., it requires no human
intervention or physical
displacement. In certain embodiments, application to the inner surface of the
container may be done
during the manufacturing of the container. The polymeric composition may be
applied using any
suitable hot melt delivery system. These systems typically include a melting
unit, which maintains
the hot melt at a temperature that will provide a material of processable
viscosity. The melting unit
typically contains a pumping system capable of pumping the hot melt through a
hose until it reaches
the glue gun, or nozzle. The nozzle can have different geometries according to
the desired
application form of the glue (coatings, stripes, beads etc). In a typical
embodiment, a slot nozzle can
be used as the glue gun.
The term "substantially soluble" as applied to a material such as the fabric
enhancer-non-
copourable perfume composition or a preferred perfumed hot melt adhesive
composition herein,
means that at least about 80%, in one embodiment at least about 90% of the
total amount of material
referred to is soluble in the total amount of fabric enhancer present in the
container.
Olfactory character of the fabric enhancer-non-copourable perfume composition
In certain embodiments, it is advantageous for the neat product odor (NPO) of
the fabric
enhancer to have a good "clean/fresh laundry" olfactory connotation that is
distinct, for example,
from a "fine fragrance" olfactory connotation. It is believed that this is due
to the fact that
consumers are likely to expect that the NPO of the products should act as a
predictor for the
expected smell of their laundry that has been washed with the product. In
other words, the selection
of olfactory character, in the consumer's mind, match the desired end use.
Therefore it is preferred that the fabric enhancer- non-copourable perfume
herein should be
formulated as a laundry perfume, focusing on volatile perfume raw materials
(PRMs) and less on
PRMs termed "residual" or "enduring" in the art. (The reverse being true for
the fabric enhancer
copourable perfume compositions further described hereinafter).
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 32
Suitable PRMs for use in the fabric enhancer- non-copourable perfume include,
but are not
limited to: aldehydic such as methylnonyl acetaldehyde, decyl aldehyde, or
lauric aldehyde; floral
such as PT bucinal, hexylcinnamic aldehyde, hexyl salicylate, benzyl acetate,
or peonile; citrus such
as orange oil, lemon oil, lemonile, gernyl nitrile, or dihydromyrcenol; fruity
such as frutene or
floracetate; green such as undecavertol, methylphenylcarbinyl actetate, beta
gamma hexenol, or
triplal; woody such as iso E super, methyl cedrylone, or patchouli; or musky
such as habanolide or
galaxolide.
Moreover, because the fabric enhancer- non-copourable perfume tends to "cover"
the full
product odor, it is preferred that the fabric enhancer- non-copourable perfume
should itself comprise
a fully formulated perfume as distinct from a simpler "accord" that blends
with the product odor.
The term "substantially insoluble" as applied to a material such as the fabric
enhancer-non-
copourable perfume composition or a preferred perfumed hot melt adhesive
composition herein,
means that less than about 20%, in one embodiment less than about 10% of the
total amount of
material referred to is soluble in the total amount of fabric enhancer present
in the container.
A "residual amount" as used herein is meant to include up to about 5% of the
original
amount by weight, in one embodiment up to about 3%, in one embodiment up to
about 1%.
Fabric Enhancer
The present products comprise a fabric enhancer. Typically the amount of the
fabric
enhancer is in accordance with the proportions by weight provided hereinabove
in defining the fabric
enhancer-non-copourable perfume composition. The fabric enhancer is typically
provided in
volumes of 1 liter, 1i/2 liter, 3 liter, or 5 liter in packages having
sufficient internal capacity when
fully loaded with the fabric enhancer to still have a headspace volume of at
least about one milliliter,
or even at least 5 milliliter.
In certain embodiments the fabric enhancers herein are pourable liquids or
gels. Such fabric
enhancers can have varying viscosities provided that they remain pourable.
Suitable viscosities,
measurement of viscosity, and thickeners/structurants are described in WO
05/012475, WO
05/059077 and WO 05/026303 which are incorporated herein by reference in their
entirety. Briefly,
the viscosity can be quantified by specifying a viscosity under a specified
constant low stress as
measured using, for example, a Carrimed CLS 100 Viscometer with a 40 mm
stainless steel parallel

plate having a gap of 500 microns. Unless indicated explicitly to the
contrary, throughout the
specification all stated viscosities are suitably measured at a shear rate of
21 s-i and at a temperature
of 25 C.
In certain embodiments, the fabric enhancer composition is a pourable liquid,
in one
embodiment having a viscosity of less than about 1,500 mPa, less than about
1,000 mPa, or even less
than about 500 mPa.
In certain embodiments, the fabric enhancer composition is a pourable gel, in
one
embodiment having a viscosity of from about 1,500 mPa to about 6,000 mPa,
about 1,500 mPa to
about 4,000 mPa, about 1,500 mPa to about 3,000 mPa, or even about 1,500 mPa
to about 2,000
mPa.
Suitable fabric enhancers comprise at least one material copourable from the
package with
the balance of surfactants and/or carriers. The material is selected from (1)
fabric enhancer-
copourable perfume compositions, (2) fabric care additives; or (3) any
combination thereof.
(1) Fabric enhancer-copourable Perfume Composition
Suitable fabric enhancers herein include those comprising a fabric enhancer-
copourable
perfume composition. The fabric enhancer-copourable perfume composition can
range in form and
may be a perfume oil or a perfume emulsion, or can be a mixture comprising
both a perfume oil and
microparticles or microencapsulates of perfumery materials.
Suitable levels of fabric enhancer-copourable perfume composition comprise
from about
0.0001 to about 25 wt%, in another embodiment from about 0.001 to about 20
wt%, in another
embodiment from about 0.001 to about 10 wt%, in another embodiment from 0.05
to 1.0 wt% of the
fabric enhancer composition.
In one embodiment, the fabric enhancer-copourable perfume composition
comprises from
0.01% to about 2% of perfume microcapsules and/or from 0.03 to about 1% of an
amine-assisted
delivery system. In one embodiment, the fabric enhancer-copourable perfume
composition
comprises from 0.1 Io to about 1 Io of perfume microcapsules and/or from 0.06
to about 0.8 Io of an
amine-assisted delivery system. In one embodiment, the fabric enhancer-
copourable perfume
composition comprises from 0.3% to about 0.9% of perfume microcapsules and/or
from 0.12 to
about 0.35% of an amine-assisted delivery system. Without wishing to be bound
by theory, the
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 34
amine-assisted delivery system can improve deposition and/or release of fabric
enhancer-copourable
PRMs from the free perfume and/or from the encapsulated perfume.
In one embodiment, the fabric enhancer-copourable perfume composition
comprises a highly
fabric substantive perfume.
In certain embodiments it may be advantageous for the fabric enhancer-
copourable perfume
composition to be fully mixed into the fabric enhancer to provide a solution,
dispersion, or
suspension. In certain such embodiments, a thickener may be used to improve
storage stability.
Preferred fabric enhancer-copourable perfume compositions comprise known
perfumery materials,
including pro-fragrances or pro-perfumes which are known in the art; see for
example WO 00/00580,
incorporated herein in its entirety by reference, which describes a beta-
ketoester pro-fragrance with
ethoxylated polyalkyleneimine and WO 99/46318, incorporated herein in its
entirety by reference,
which describes a silicone pro-fragrance, and US Patent No. 7,071,151
incorporated herein in its
entirety by reference, which describes a light-triggered pro-fragrance.
Fully formulated perfumes, as distinct from simple accords or single perfumery
compounds,
are preferred. In certain embodiments the fabric enhancer-copourable perfume
composition
comprises a mixture of a liquid perfume formulation together with perfume
microcapsules.
Moreover, when using perfume microcapsules or amine-assisted perfume delivery,
the invention
includes embodiments in which no conventional liquid perfume formulations are
added to the fabric
enhancer.
Perfume microcapsules herein are any encapsulated perfumes having the form of
discrete
particles having sizes sufficiently small to be dispersed or suspended in the
fabric enhancer
compositions herein, so that they are pourable from the package along with the
fabric enhancer
composition. "Encapsulated" means that there will generally be present one or
more coating layers
enclosing the perfume. The perfume contained in the encapsulate can be in
liquid or solid form and
can be homogeneously or non-homogeneously distributed. Suitable particle sizes
range from
nanometer scale to micron scale and even to millimeter scale. Typical particle
sizes range from 1
micron to 1 mm. In embodiments herein, encapsulated perfume leaves little or
no visible residues on
fabrics onto which it is deposited. In one embodiment, the microcapsule
particle size ranges from
about 1 micron to about 60 microns; in another embodiment from 5 micron to 30
micron.
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 35
In preferred embodiments perfume microcapsules have a measurable increase in
deposition
onto fabrics during laundering with the fabric enhancer, by virtue of chemical
and/or physical
mechanisms ranging from having a particle size suitable for being entrapped in
fabrics by filtration,
through to electrostatic attraction to (typically negatively charged) fabrics
by virtue of having
opposite net surface charge. In other embodiments, the perfume microcapsules
are those which
adhere to fabrics by virtue of tackiness, more specifically, having a work of
adhesion consistent with
tacky particles.
Suitable encapsulated or microencapsulated perfumes, i.e., perfume
microcapsules, are
described in U.S. 2004/0072719, U.S. 6,225,372, U.S. 6,359,031, U.S.
4,234,627, U.S. 3,516,941,
U.S. 6,916,780, U.S. 4,919,841, U.S. 5,281,356, U.S. 5,281,357, U.S. 5,281,355
and under
Fragrance Encapsulation in Kirk Othmer's Encyclopedia of Chemical Technology,
which are
incorporated herein by reference in their entirety. Suitable encapsulation
systems include, but are
not limited to waxes, aminoplasts, and emulsion polymerized systems. Coatings
may be cationic,
anionic or non-charged. In encapsulating perfumes for use in the fabric
enhancer-copourable
perfume composition, it is preferred both to (i) reduce or limit diffusion of
perfume into the fabric
enhancer and (ii) to enhance the fabric substantivity of the perfume, suitably
as taught, for example,
in Example 7 of the hereinbefore-referenced U.S. 2004/0072719 Al which makes
use of a specific
cationic coating applied to perfume-loaded melamine-formaldehyde capsule
slurries commercially
available from Cytec Industries. Uniformly sized particles can be made by
processes such as that
described in U.S. 6,890,592, incorporated herein by reference in its entirety.
In other embodiments the fabric enhancer-copourable perfume composition
comprises a
mixture of a liquid perfume formulation together with an amino or polyamino-
functional compound,
which is optionally premixed with the liquid perfume. Such uses of polyamino
or polyimine
compounds to enhance fabric deposition of perfumes herein are collectively
referred to as involving
an "amine-assisted perfume delivery matrix", or in alternate terms, "amine-
assisted perfume", or in
alternate terms, "amine-assisted delivery system", or in alternate terms,
"amine-polymer-assisted
delivery system" or in alternate terms, "APAD system". In another embodiment,
the polyamino or
polyimine compound is added separately from the fabric enhancer-copourable
perfume composition.
An amine-assisted perfume or perfume delivery system herein includes any
perfumery
compound or mixture of perfumery compounds having improved deposition on
fabrics when
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 36
laundered in the presence of the fabric enhancer, by virtue of a chemical
and/or physical interaction
between the perfumery compound or mixture of perfumery compounds and an
organic amine or
polyamine. The amine or polyamine can be added to the fabric enhancer
separately from, or
together with, perfumery compounds. In one embodiment the amine or polyamine
is not in the form
of a premix with perfumery compounds, it is added separately to the fabric
enhancer. The amine or
polyamine in one embodiment comprises at least one, in one embodiment a
plurality of, primary
and/or secondary and/or tertiary amine moieties. In preferred embodiments
comprising amine-
assisted perfumes or amine- or polyamine-assisted perfume delivery systems,
the amine has a low
vapor pressure and little or no inherent odor, for example having a normal
boiling point of at least
200 deg. C. Amine-assisted perfumes herein generally comprise no enzymatic
proteins as the
essential polymeric aminofunctional perfume deposition enhancing material of
such embodiments.
Moreover amine-assisted perfumes herein generally comprise at most very low
levels, in one
embodiment less than 1 ppb, of malodorous low-boiling amine impurities, e.g.,
trimethylamine. In
embodiments herein, the amine-assisted perfume leaves little or no visible
residues on fabrics onto
which it is deposited. Single and multiple APAD systems are contemplated.
Without wishing to be
bound by theory, it is believed that different APAD systems have inproved
efficacy as related to
different perfumes. The combination of different APAD systems thereby improves
the deposition
and release of perfumes, particularly multiple component perfumes.
In one aspect, said APAD system comprises a polyalkylamine. In one aspect,
said
polyalkylamine comprises a polyethyleneamine or polyvinylamine. In one aspect,
said
polyethylenamine has a weight average molecular weight in daltons, as
determined by dynamic light
scattering (DLS) using a Malvern Zetasizer Nano-ZS, supplied by Malvern
Instruments Ltd Enigma
Business Park, Grovewood Road Malvern Worcestershire WR14 1XZ United Kingdom,
of from
about 500 to about 5,000,000, from about 1000 to about 1,000,000, or from
about 7,000 to about
200,000.
In one aspect, said APAD system comprises a polymer which is made by
polymerization of
ethyleneimine. In another embodiment, the said polymer is water-soluble or
partly water-soluble.
In a particularly preferred embodiment, the APAD system comprises an amine-
based polymer that is
partly branched and contains primary, secondary and tertiary amines. Without
wishing to be bound
by theory, the combination of polar groups (amines) and hydrophobic groups (-
CH2CH2-) imparts to
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 37
the polymer adhesive characteristics and the ability to interact with a
variety of organic materials,
including but not limited to, perfume raw materials, perfume microcapsules,
and other formulation
components such as surfactants. For example, when the APAD system is
formulated into a fabric
enhancer, the APAD system may interact with carry-over surfactant from the
wash process and/or
cationic softener from the rinse process. Again without wishing to be bound by
theory, such
interactions may increase the deposition of other soluble or insoluble
materials, such as perfume raw
materials and/or perfume microcapsule particles. As such, the APAD system may
impart improved
softness or feel benefits as well as impart improved perfume delivery. Such
improved perfume
delivery can take the form of improved perfume deposition and/or release,
which may be realized at
any of the important consumer touch points, such as neat product odor, wet
fabric odor, in-use room
odor, or scent of laundry immediately out of the dryer or at any later dry
fabric moment.
In yet another aspect of the present inventions, it was surprisingly found
that APAD systems
selected from polymers made from polymerization of ethyleneimine which have an
average
molecular weight in Daltons from about 20,000 to about 100,000 or from about
60,000 to about
80,000 provide best combination of both freshness and softness benefits. An
example of such an
APAD system includes polyethyleneimine polymers available from BASF that are
known as
Lupasol polymers or from Nippon Shokubai that are known as EPOMIN polymers.
Examples
include Lupasol WF and Lupasol HF and EPOMIN P-1000 or P-1050.
In another aspect of the present invention, the freshness and softness
benefits are delivered
via formulations containing free perfume and perfume microcapsules.
It has also been surprisingly found that the proper ratio of APAD to other
polymers in the
fabric enhancer formulation is critical to performance. In one embodiment, the
ratio of
polyethyleneimine polymers to other non-polyethyleneimine polymers in the
formulation is from
about 0.01 to about 10, in another embodiment from about 0.1 to about 2.0, in
another embodiment
from about 0.15 to 0.40. In another embodiment, the non-polyethyleneimine
polymer is a cationic
starch, for example, a cationic high amylose maize starch available from
National Starch under the
trade name CATO . In another aspect, the polyamino or polyimine compound is
neutralized or
made acidic prior to addition of said polyamino or polyimine compound prior to
combining with
other fabric enhancer formulation ingredients. In yet another aspect, the
polyamino or polyimine
compound is in one embodiment diluted with water and neutralized to a pH from
about 1 to 7, or
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 38
from about 2 to 5, or from about 3 to 4 prior to combining with other fabric
enhancer formulation
ingredients, including fabric enhancer-copourable perfume composition.
In certain embodiments, the polyethylenamine can improve fabric softness,
provide silky feel,
and improve shape retention.
In embodiments of the invention comprising amine-assisted perfume delivery
and/or perfume
microcapsules, at least about 0.001, in another embodiment at least 0.01, in
another embodiment, at
least 0.1, in another embodiment at least 1 weight fraction of the fabric
enhancer-copourable
perfume composition is incorporated into a polyamine-assisted delivery matrix,
a perfume
microcapsule, or any combination thereof. Amine or polyamine assisted perfume
systems for use as,
or as part of, the fabric enhancer-copourable perfume composition are

fixatives are described on page 35 of WO 00/27958 which is incorporated by
reference and are
commercially marketed by Ciba and Clariant.
In certain embodiments, the fabric enhancer comprises a silicone polymer or a
blend of
silicones, e.g., a blend comprising at least one aminofunctional silicone.
Suitable aminofunctional
silicones are described, for example, in WO 05/007790, WO 04/046452, WO
04/042136, WO
04041987, and WO 04/041912 which are incorporated by reference in their
entirety. Coacervate
phase forming polymers may be added, as described in WO 04/041983. Other
suitable
aminosilicones may be used, such materials being commercially available from
Dow Corning,
Wacker Chemie and other suppliers. Silicone copolymers or blends thereof,
especially those
containing non-yellowing aminosilicones, can improve fabric softness, provide
silky feel, and
improve shape retention.
In certain embodiments, the fabric enhancer comprises a cationic silicone
polymer. Suitable
cationic silicone polymers are described, for example, in U.S. 6,903,061,
which is incorporated in its
entirety by reference. In certain such embodiments, the cationic silicone

acids are listed in US
5,759,990 at column 4, lines 45-66. In one embodiment the FSA comprises other
actives in addition
to DQA (1) or DQA. In yet another embodiment, the FSA comprises only DQA (1)
or DQA and is
free or essentially free of any other quaternary ammonium compounds or other
actives. In yet
another embodiment, the FSA comprises the precursor amine that is used to
produce the DQA.
In another aspect of the invention, the FSA comprises a compound, identified
as DTDMAC
comprising the formula:
[R4-m - N(+) - R1m] A-

In one embodiment, the FSA comprises an FSA described in U.S. Pat. Pub. No.
2004/0204337 Al, published Oct. 14, 2004 to Corona et al., from paragraphs 30 -
79.
In another embodiment, the FSA is one described in U.S. Pat. Pub. No.
2004/0229769 Al,
published Nov. 18, 2005, to Smith et al., on paragraphs 26 - 31; or U.S. Pat.
No. 6,494,920, at
column 1, line 51 et seq. detailing an "esterquat" or a quaternized fatty acid
triethanolamine ester salt.
In one embodiment, a dispersion polymer is added to the composition. Such
dispersion
polymers include cationic and anionic dispersion polymers. In one embodiment,
non-acrylamide
based polymers are contemplated. An exemplary cationic dispersion polymer is
made by Ciba
under the trade name Rheovis CDE. Without being bound by theory, it is
believed that the
dispersion polymer suspends microcapsules present within the composition.
Moreover, these
dispersion polymers also function as APAD systems.
Other adiuncts
Fabric enhancers herein may comprise small amounts of conventional
surfactants, at levels of
from about 1 to about 80 wt.%, in one embodiment from about 1 to about 50
wt.%. In an alternative
embodiment, fabric enhancers may comprise less than 1% surfactant, in another
embodiment less
than 0.5% surfactant, in another embodiment less than 0.01% surfactant, in
another embodiment be
free of surfactant. Surfactants may be of anionic, nonionic, zwitterionic,
amphoteric or cationic or
any compatible mixtures thereof.
The fabric enhancers according to the present invention also contain an
aqueous carrier; in
certain embodiments the carrier may be thickened or non-thickened, and in
certain embodiments the
carrier may further include a conventional hydrotrope. Generally the amount of
the aqueous carrier
employed in the compositions herein will be relatively large. In one
embodiment, the compositions
of the present invention comprise from about 40% to about 80% of an aqueous
liquid carrier. The
most cost effective type of aqueous, non-surface active liquid carrier is, of
course, water itself.
Accordingly, the aqueous, non-surface active liquid carrier component will
generally be mostly, if
not completely, comprised of water. Other water-miscible carriers, such as
alkanols, diols, polyols,
ethers, amines, alkanolamines, and similar solvents may be added to fabric
enhancer as co-solvents
or stabilizers. Accordingly, the aqueous liquid carrier component of the
fabric enhancer products
herein, including organic solvents if present, will generally comprise water
present in concentrations
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 45
ranging from about 30% to 93%, in one embodiment from about 35% to about 50%,
by weight of the
composition. In certain embodiments, the level of any non-water solvent will
be minimized, e.g.,
not more than about 10%, in one embodiment not more than about 5%, in one
embodiment not more
than about 1% of non-water solvents will be present in the fabric enhancers.
In one embodiment, the composition of the present invention may comprise any
one or more
adjunct ingredients. In yet another embodiment, the composition of the present
invention may be

composition comprises
an adjunct ingredient up to about 2% by weight, in another embodiment up to
about 10%, in another
embodiment, up to about 20% of the composition.
Other embodiments are possible within the spirit and scope of the invention.
Such
embodiments include products having a cap or over-cap which can be used as a
measuring device. It
is possible to include a separate portion of fabric enhancer-non-copourable
perfume composition
which is affixed to such a measuring device. It is furthermore possible for
the invention to include
multi-compartment, e.g., dual compartment, bottles, with the fabric enhancer-
non-copourable
perfume composition present to perfume the headspace of one or both
compartments. It is possible to
use the invention in conjunction with fabric enhancer products which are fully
transparent, hazy or
opaque, e.g., as a result of incorporating an opacifier or pearlescent agent,
or in cases where the
CA 02679120 2009-08-21
WO 2008/111007 PCT/IB2008/050932
10747/JC 46
fabric enhancer is inherently hazy. It is moreover possible to use the
invention in conjunction with
fabric enhancer products comprising more than one fluid phase, such as a so-
called "split phase"
fluid.
The term "ambient storage temperature" as used herein is in the range from
about 0 C to
about 50 C, in one embodiment from about 5 C to about 40 C, in one
embodiment from about
C to about 30 C, suitably about 25 C.
The term "copourable" as used herein means that the material referred to pours
out of the
package along with the fabric enhancer at ambient temperature. Examples of
copourable materials
include those which are soluble in, or suspendable in, the fabric enhancer.
Preferred copourable
perfumes include perfumes that are emulsifiable in the fabric enhancer,
soluble in the fabric
enhancer, or suspendable as small particles (e.g., having size from nanometer-
scale to about 2
millimeters) in the composition as determined at ambient storage temperature.
The term "fluid" as used herein is meant to include compositions that are
pourable at ambient
temperature. Such compositions include, but are not limited to, liquids and
gels.
The term "headspace" as used herein refers to an accessible headspace and is
meant to
include the vapor located above the fabric enhancer in a package or container
that enables the odor
of the contents of the package or container to be detected by the user. In one
embodiment the
headspace is located in the package at a location that suitable for olfactory
sampling by a consumer
on opening the closure of the package. A typical headspace volume is from 5%
to 10%, suitably 8%
v/v (volume/volume) - in other words, a package suitably comprises 92% by
volume of fabric
enhancer and 8% headspace by volume.
The term "tackifier" or "tackifier resin" herein is as used in the art of
adhesives, more
specifically hot-melt adhesives. See US 4,623,698. A tackifier is optionally
added when making the
fabric enhancer-non-copourable perfume composition, in order to improve its
tackiness. Tackifiers
are available commercially from suppliers such as Dupont under the ELVAX
tradename or from
Eastman under the FORALYN tradename.
