TITLE OF THE INVENTION

Malodor Reducing Compositions and Methods
BACKGROUND OF THE INVENTION

[0002] Liquid fabric softener compositions are typically used in the rinse
cycle of
laundry washing machines to impart anti-static properties to washed fabrics,
to provide
desirable scents and to provide the fabrics with a texture that is soft,
smooth, and
pliable to the touch. Similarly, sheets containing fabric softeners are
typically used in
laundry dryers, and the fabric softener is imparted to fabrics by repeated
contact during
the drying process. Conventional softeners may disguise the odors, but do not
remove
them completely.
[0003] Body malodors impart offensive odors by impregnating fabrics and
clothing. Such malodors may persist even after laundering. Body malodors have
a
particular tendency to impregnate synthetic materials (which are often
hydrophobic),
and therefore tend to have a greater affinity for sebum. The malodor
components also
tend to be extremely difficult to remove from synthetic materials, and are
often slowly
released even after laundering of fabrics and clothing.

[0004] Accordingly, there is a need for compositions that are effective in
controlling malodors on fabrics, as well as compositions effective in reducing
malodors
on fabrics after laundering of the fabrics and clothing.

BRIEF SUMMARY OF THE INVENTION
[0005] A method of reducing malodor comprising:
(a) applying a soil release polymer (SRP) composition in an
aqueous solution to a fabric; and
(b) rinsing said fabric;
1


CA 02628972 2010-03-10
62301-2747

wherein said SRP composition is substantially free of anionic surfactants
and/or
builder salts.

[0006] A method of reducing malodor comprising:

(a) applying a soil release polymer (SRP) composition in an aqueous
solution with a fabric softening component to a surface; and

(b) rinsing said surface;

wherein said SRP composition is substantially free of anionic surfactants
and/or
builder salts.

According to one aspect of the present invention, there is provided a
method of reducing malodor comprising: (a) applying a fabric softening
composition in an aqueous solution to a fabric; and (b) rinsing the fabric;
wherein
the fabric softening composition comprises a water-soluble soil release
polymer
(SRP) and a fabric softening component and the fabric softening composition is
substantially free of anionic surfactants and/or builder salts; the SRP is 0.1
to 40
wt% of the total weight of the composition; and the fabric softening
composition is
added to the rinse cycle of a laundry washing machine while the fabric is
being
rinsed.

DETAILED DESCRIPTION OF THE INVENTION

[0007] As used throughout the present disclosure, ranges are a shorthand
for describing each and every value within the range. Any value within the
range
can be selected as the terminus of the range. In addition, all references
cited in
the present disclosure are hereby incorporated by reference in their
entireties.
Percentages given below are percent of total weight unless otherwise
indicated.:
[0008] In certain embodiments, the present invention provides methods of
reducing malodor comprising applying a composition comprising a soil release
polymer in an aqueous solution to a fabric. The soil release polymer (SRP) may
be a co-polymer of a water-soluble polyether and a polyester, for example, a
cellulose polyester polymer or a polyethylene glycol polyester, such as

2


CA 02628972 2010-03-10
62301-2747

1,4-benzenedicarboxylic acid polymer with 1,2-ethanediol and alpha-hydro-
omega-hydroxypoly(oxy-1,2-ethanediyl). In certain embodiments, the soil
release
polymer is water soluble. In certain embodiments, the soil release polymer is
nonionic.

[0009] In certain embodiments, the composition comprising the SRP for use
in the method of the invention is not a component of a laundry detergent,
i.e., the
formulation comprising the SRP is substantially free of anionic surfactants
and/or
substantially free of builder salts.

2a


CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
[0010] In certain embodiments, the invention provides methods of effecting one
or more of the following results: reducing accumulation of malodors, reducing
malodor, reducing the perception of malodor, or inhibiting malodor deposition
on
fabrics.

[0011] In certain embodiments, the methods of the present invention comprise
the step of applying a composition comprising a soil release polymer in an
aqueous
solution to the fabric. In various embodiments, the methods may comprise any
of the
following: submerging a fabric in an aqueous solution comprising the SRP;
adding to
the composition comprising the SRP to the rinse cycle of a laundry washing
machine
while the fabric is being rinsed; adding the composition comprising the SRP to
water
and not directly on the fabric; spraying the composition comprising the SRP
onto the
fabric; rinsing the fabric after application of the SRP; and other similar
methods of
contacting the fabric with the SRP.

[0012] As used herein, the term "fabric" includes fabrics comprising natural
fibers, such as, e.g., cotton, wool, silk or mixtures thereof. In other
embodiments, the
fabric comprises synthetic fibers, such as, e.g., polyester, spandex/nylon,
viscose, satin,
velvet, acetate, acrylic and the like. The fabric may also comprise a blend or
combination of natural and synthetic fibers. The fabric may be of any
conventional
form; e.g., woven, non-woven or pressed.

[0013] It should be noted that as used herein, "fabric" includes items that
are
typically worn as clothing or otherwise come into contact with the human body.
For
example, plastic, vinyl, polymers such as polyvinyl chloride, surfaces of
chairs, car
seats, protective gear worn for sports (e.g., protective pads, helmets and
gloves) are
examples of fabrics that can be treated in accordance with the methods of the
present
invention. In various embodiments, the malodor to be treated is human body
malodor.

[0014] In certain embodiments, the present invention provides fabric softener
compositions comprising:

3


CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
(a) one or more water-soluble soil release polymers (SRPs), e.g., polymers of
a water-soluble polyether and a polyester, such as a nonionic polymer, for
example a
cellulose polyester polymer or a polyethylene glycol polyester, such as 1,4-
benzenedicarboxylic acid polymer with 1,2-ethanediol and alpha-hydro-omega-
hydroxypoly(oxy-1,2-ethanediyl) (e.g., SorezTM 100, available from
International
Specialty Products, Wayne, New Jersey, USA) ; and

(b) one or more fabric softening components, e.g., a quaternary ammonium
compound, e.g., a polyquat or an esterquat, for example a triethanolamine
esterquat,
e.g., triethanolamine-esterquat tallow;

wherein the composition is substantially free of anionic surfactants and/or
substantially free of builder salts.

[0015] The amount of the components of the present compositions depends on
whether a given composition is concentrated or dilute, as well as on the
precise
selection of components. Thus, the fabric softening component may be, for
example,
about 0.1 to about 40 % of the total weight of the composition in certain
embodiments,
about 0.5 to about 25% of the total weight of the composition in other
embodiments,
e.g., about 6 to about 24% for a concentrated composition or about 1.5 to
about 6% for a
dilute composition.

[0016] The soil release polymer (SRP) may be present in an amount of, for
example, about 0.1 % to about 40 % in certain embodiments, about 0.5 to about
10 % of
the total weight of the composition in other embodiments, about 1 to about 6 %
of the
total weight of certain embodiments directed to a concentrated composition, or
about
0.2 to about 2% of the total weight of certain embodiments directed to a
dilute
composition.

[0017] Preferably the ratio by weight of fabric softening component to SRP is
about 30:1 to about 1:30. In various embodiments, the ratio is about 2:1 to
about 20:1,
or about 3:1 to about 10:1.

[0018] The composition may further comprise one or more chelators, colorants
(e.g., dyes or pigments), fatty alcohols (for example, a C16-18 fatty
alcohol),

4


CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
preservatives (for example, lactic acid) and/or perfumes, and/or other
ingredients as
known in the art of fabric softening compositions. For example, in certain
embodiments, the compositions further comprise a chelator that is
aminotrimethylene
phosphonic acid.

[0019] In certain embodiments, the compositions are in an aqueous solution. In
such embodiments, the compositions may be diluted by water in amounts of, for
example, about 1:1 to about 1:1000 by weight, or about 1:1 to about 1:1000 by
volume.
[0020] In certain embodiments, the present invention provides a fabric
softener
composition as described above, wherein the water soluble soil release polymer
is a
polyethylene glycol polyester. The polyethylene glycol polyester may be, for
example,
a co-polymer of 1,4-benzenedicarboxylic acid polymer with 1,2-ethanediol and
alpha-
hydro-omega-hydroxypoly(oxy-1,2-ethanediyl).
[0021] In certain embodiments, the fabric softening component is an esterquat.
Such esterquat may be, for example, a compound of Structure 1 depicted below:

R +
2
,. R3
O
(CH2)q O C R4
STRUCTUREI
wherein

Ri represents (CH2)tR6 where R6 represents benzyl, phenyl, (C1-C4)-alkyl
substituted phenyl, OH or H;

R2 and R3 represent (CH2),-R5 where R5 represents an acyloxy group containing
from 8 to 22 carbon atoms, benzyl, phenyl, (C1-C4)-alkyl substituted phenyl,
OH or
H;



CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
R4 represents an aliphatic hydrocarbon group having from 8 to 22 carbon
atoms;

q, s, and t, each independently, represent an integer from 1 to 3; and
X- is a softener compatible anion.

[0022] In certain embodiments, R1 is C1-C4 alkyl (e.g., methyl). In certain
embodiments, R2 and R3 are independently or both J3-C8-C22-acyloxy ethyl or J3-

hydroxy ethyl. For example, in one embodiment, one of R2 and R3 is f3-C8-C22-
acyloxy
ethyl and the other is P-hydroxy ethyl. In certain embodiments, q and s are 2.
In
certain embodiments, X- is sulfate.

[0023] In certain embodiments, the esterquat is a triethanolamine esterquat
(e.g.,
a di-alkyl ester of triethanol ammonium methyl sulphate). In certain
embodiments,
the fabric softening component is a triethanolamine esterquat in amounts of
about 10
to about 20%. In certain embodiments, the fabric softening component is a
polyester
polyethyleneglycol polymer in amounts of about 1 to about 6% by weight. In
certain
embodiments, the compositions comprise: (a) a triethanolamine esterquat in
amounts
of about 2.5 to about 5% by weight; and (b) a polyester polyethylene glycol
polymer in
amounts of about 0.2 to about 1.5% by weight.

[0024] The invention further comprises the use of a soil release polymer
(SRP),
e.g., a polyethyleneglycol polyester polymer as described herein, to control
malodor. In
certain embodiments, the invention is further directed to a method of
conditioning
fabric comprising applying a composition as taught herein to a fabric as the
fabric is
being rinsed with water.

[0025] The present invention is related to a fully unexpected and innovative
benefit that is provided by soil release polymers (SRPs) in rinse cycle fabric
conditioning compositions. SRPs are compounds that may be used in detergent
compositions to provide benefits, such as related removal of greasy stains and
for anti-
stain redeposition, specifically on hydrophobic fabrics such as synthetic
fibers, e.g.,
polyester. However, it has additionally been discovered herein that use of
SRPs in

6


CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
fabric softener compositions inhibits the deposition of sebum and human sweat
on
fabrics (especially synthetic fabrics), inhibits malodor absorption into the
fabrics, and
reduces the perception of body malodors while improving the perception of
freshness.
SRPs may also prevent and/or inhibit the encrustation of malodors, such as
perspiration and sebum, in such fabrics. SRPs may have in the past frequently
comprised water-insoluble components, such as polyesters, and were not used in
fabric softener compositions. Additionally, because SRPs were present in
laundry
detergents, there was no motivation to add SRPs to fabric softener
compositions.
Certain embodiments of the present invention are directed to fabric softener
compositions having a water soluble SRP.

[0026] As used herein, the terms "soil release polymer" or "SRP" are used
interchangeably, and may include polymers that are absorbed onto fabric fibers
where
they counteract resoiling of the fibers. The soil release polymer may be a co-
polymer
of a water-soluble polyether and a polyester, for example a cellulose
polyester
polymer or a polyethylene glycol polyester, such as 1,4-benzenedicarboxylic
acid
polymer with 1,2-ethanediol and alpha-hydro-omega-hydroxypoly(oxy-1,2-
ethanediyl). The polymers thus may include polyesters and co-polymers of
terephthalic acid, polyesters of and co-polymers of ethylene glycol,
copolymers of
ethylene glycol and benzene, and polyethylene terephthalate. The polymers may
include nonionic polyesters. The polymers may be modified whereby a portion of
the
ethylene glycol is removed and replaced with a high molecular weight hydroxy-
terminated polyethylene glycol.

[0027] In certain embodiments, the SRP is hydrophilic, or may be miscible or
soluble in water at any ratio. In various embodiments, the SRP in the present
invention is water soluble, for example, readily soluble in cold, warm, and
hot water.
Preferred SRPs may also be a polymer of polyethylene glycol and polyester or
cellulose ether and polyester.

[0028] In certain embodiments of the invention, the SRP used is 1,4-
benzenedicarboxylic acid polymer with 1,2-ethanediol and alpha-hydro-omega-
7


CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
hydroxypoly(oxy-1,2-ethanediyl). In certain embodiments, the SRP used is a
polyethylene glycol polyester. In certain embodiments, a water soluble SRP is
used,
for example one that may be purchased from International Specialty Products
(Wayne,
New Jersey, USA) under the trade name SorezTM 100. In other embodiments, the
SRP
used may be purchased from Clariant GmbH (Sulzbach, Germany) under the trade
name TexCare SRN 170. In certain embodiments, the present invention comprises
about 0.1 % to about 40 % weight of a SRP component.

[0029] In certain embodiments, the SRP is about 0.1 % to about 40 % of the
total
weight of the composition; in other embodiments about 2 to about 6% of the
total
weight of the composition, in other embodiments about 0.5 to about 2% of the
total
weight of the composition.

[0030] Fabric softeners may contain a fabric softening component, and may
optionally contain additional components, including perfumes, chelators,
preservatives, dyes, or thickeners. Other optional ingredients may also
include,
without limitation: solvents, alcohols, amphoteric and non-ionic surfactants,
fatty
alcohols, fatty acids, organic or inorganic salts, pH buffers, antifoams,
germicides,
fungicides, antioxidants, corrosion inhibitors, enzymes, optical brighteners,
antifoams,
and combinations thereof and other materials known in the art.
[0031] In certain embodiments, the present invention is substantially free of
anionic surfactants and/or builder salts. As used herein, "substantially free"
means,
in various embodiments, less than about 5 % weight, less than about 1 % by
weight, less
than about 0.5 % by weight or less than about 0.1 % by weight of a given
component.
[0032] Anionic surfactants include those known in the art, for example,
lithium
dodecyl sulfate or sodium dodecyl sulfate. Water soluble builder salts known
in the
art include, for example, alkali metal phosphates, e.g., sodium phosphate and
potassium phosphate. In various embodiments, the compositions of the present
invention are substantially free of either anionic surfactants, water soluble
builder
salts or both.

without limitation: cationic surfactants, quaternary ammonium salts (e.g.,
acyclic
quaternary ammonium salts, ester quaternary ammonium salts, cyclic quaternary
ammonium salts, diamido quaternary ammonium salts, biodegradable quaternary
ammonium salt, polymeric ammonium salts), polyquats, tertiary fatty amines,
carboxylic acids, esters of polyhydric alcohols, fatty alcohols, ethoxylated
fatty
alcohols, alkyphenols, ethoxylated alkyphenols, ethoxylated fatty amines,
ethoxylated
monolycerides, ethoxylated diglycerides, mineral oils, clays, and polyols and

or a
dihydrogenated tallowoylethyl hydroxyethylmonium methosulfate. Preferred
fabric
softening components may be purchased from Kao Corporation (Japan) under the
TM
product name Tetranyl L1/90.

[0034] In certain embodiments, the compositions comprise about 0.01 % to about
35% by weight of one or more fabric softening components. In certain
embodiments,
the compositions comprise about 0.1% to about 25% weight of one or more fabric
softening components. In certain embodiments, the compositions comprise about
1.5% to about 6% of one or more fabric softening components. In other
embodiments,
the compositions comprise about 6% to about 24% of one or more fabric
softening
components. In certain embodiments, the compositions of the present invention
are
useful as fabric softeners that may be added to the rinse cycle of a laundry
process.
[0035] The fabric softener compositions of the present invention may be
applied
to fabrics, e.g., clothing, using a variety of methods. In certain
embodiments, the SRPs
are highly soluble in water. Accordingly, the SRP may be incorporated into an
aqueous solution, and the aqueous solution may be added to the rinse cycle of

invention

9


CA 02628972 2008-05-07
WO 2007/059532 PCT/US2006/061034
may be diluted in the range of about 1:1 to about 1:1000 in water when added
to the
rinse cycle of a laundry washing machine. In alternative embodiments, the SRP
may
be dissolved in water to produce a solution of about 0.0005% to about 40% by
weight,
and sprayed onto fabrics. Alternatively, the SRP may be in an aqueous solution
and
sprayed or applied onto fabrics and hard surfaces. Alternatively, the SRP may
be in
the continuous phase of an oil-in-water emulsion, and sprayed or applied onto
fabrics
and hard surfaces. Alternatively, the SRP may be in the discontinuous phase of
a
water-in-oil emulsion, and sprayed onto fabrics and hard surfaces. In such
embodiments, excess liquids may then be wiped off fabrics or hard surfaces.
[0036] Chelating agents are known in the art, and may be present in the
compositions of the present invention, in various embodiments at a level of at
least
about 0.001 % by weight of the fabric softening composition, about 0.001 to
0.5 % of the
composition, about 0.003 to about 0.5% or 0.005% to 0.25%. Chelating agents
useful
for the present invention include, without limitation: amino carboxylic acid
compounds and organo aminophosphonic acid compounds, and mixtures of the same.
Suitable amino carboxylic acid compounds may include: ethylenediamine
tetraacetic
acid, N-hydroxyethylenediamine triacetic acid, nitrilotriacetic acid, and
diethylenetriamine pentaacetic acid. Suitable organ aminophosphonic acid

[0042] Thirty-six patches of polyester, nylon/Lycra, and viscose fabrics are
cut
into 25 x 25 cm sheets. The fabrics are washed in a laundry washing machine at
50 C
with detergent. During the rinse cycle, half of the fabrics are treated with
FC#1, and
half of the fabrics are treated with FC#2. The fabrics are dried in an
electric tumble
dryer.

[0043] 1.6 grams of artificial sweat soil and 1.6 grams of sebum dispersion
(compositions given in Tables 1 and 2) are sprayed on each fabric, and the
fabrics are
dried for 30 minutes on a line. The fabrics are again washed in laundry
washing
machine and during the rinse cycle, fabrics treated with FC#1 are treated with
FC#1,
and fabrics treated with FC#2 are treated with FC#2. The fabrics are dried in
an
electric tumble dryer. The soiling and washing cycle is repeated several
times.

[0044] A panel of 18 judges is asked to compare fabrics treated with FC#1 and
fabrics treated with FC#2 after 5 and then 10 cycles of soiling and washing
cycle, for
both wetted and dried fabrics, and during ironing after 10 cycles of soiling
and

washing cycle to give their sensory preference (if any) to each fabric. The
results of the
comparison are given below in Tables 3 - 7, the first number being the number
judges
preferring FC#2 treated fabrics; the second number being the number of judges
preferring FC#1 treated fabrics, and the third number being the number of
judges
with no preference between FC#1 and FC#2 treated fabrics. The probability that
FC#1
and FC#2 treated fabrics are different is given in the parentheses.

[0045] It is shown that FC#2, which contains 1 % polyethylene glycol
polyester,

has a significant benefit over FC#1 on the perception of freshness and
reduction of the
perception of body malodors after 5 and 10 cycles on wet and dry fabrics
(dried on
line).
