FABRIC MAINTENANCE COMPOSITIONS COMPRISING CERTAIN CATIONICALLY
CHARGED FABRIC MAINTENANCE POLYMERS
FIELD OF THE INVENTION
The present invention relates to fabric dye maintenance compositions which
comprise
one or more dye maintenance compounds which can be oligomers, polymers, co-
polymers, and
the like which comprise one or more monomers which results in the final dye
maintenance
compound having a net positive charge. Compositions comprising the dye
maintenance
polymers of this invention impart appearance and integrity benefits to fabrics
and textiles treated
with solutions formed from such compositions.
BACKGROUND OF THE INVENTION
It is, of course, well known that alternating cycles of using and laundering
fabrics and
textiles, such as articles of worn clothing and apparel, will inevitably
adversely affect the
appearance and integrity of the fabric and textile items so used and
laundered. Fabrics and
textiles simply wear out over time and with use. Laundering of fabrics and
textiles is necessary
to remove soils and stains which accumulate therein and thereon during
ordinary use. However,
the laundering operation itself, over many cycles, can accentuate and
contribute to the
deterioration of the integrity and the appearance of such fabrics and
textiles.
Deterioration of fabric integrity and appearance can manifest itself in
several ways.
Short fibers are dislodged from woven and knit fabric/textile structures by
the mechanical action
of laundering. These dislodged fibers may form lint, fuzz or "pills" which are
visible on the
surface of fabrics and diminish the appearance of newness of the fabric.
Further, repeated
laundering of fabrics and textiles, especially with bleach-containing laundry
products, can
remove dye from fabrics and textiles and impart a faded, worn out appearance
as a result of
diminished color intensity, and in many cases, as a result of changes in hues
or shades of color.
Given the foregoing, there is clearly an ongoing need to identify materials
which could
be added to fabric treatment products, specifically to rinse added fabric
conditioners, pre-wash
spray on compositions, pre-soak compositions as well as after wash or between
wash malodor

WO 00/56848 CA 02365282 2001-08-31 PCT/US00/08030

control or fabric re-freshening compositions, materials which would associate
themselves with
the fibers of the fabrics and textiles thereby reducing, abating, or
minimizing the tendency of the
fabric/textiles to deteriorate in appearance. Any such fabric treatment/fabric
maintenance
composition additive material should, of course, be able to benefit fabric
appearance and
integrity without unduly interfering with the ability of the balance of
laundry products to perform
their intended function. The present invention is directed to the use of dye
maintenance polymers
in fabric treatment and fabric enhancement compositions which perform in this
desired manner.
SUMMARY OF THE INVENTION
The present invention meets the aforementioned need in that it has been
surprisingly
discovered that fabric which is treated, and subsequently re-treated with the
compositions of the
present invention, will resist normal fading and color loss without regard to
the circumstances,
inter alia, due to mechanical wear and abrasion. In addition, fabric which has
not been treated
can have the loss of fabric dye attenuated by adding the compositions of the
present invention to
the laundry cycle as an adjunct via pre-soak, rinse additive, etc. The
compositions of the present
invention can be added is any manner, inter alia, as part of a formulation or
as a separate
composition.
The first aspect of the present invention relates to compositions providing
dye protection
benefits to fabric comprising:

claims. All percentages, ratios and proportions herein are by weight, unless

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to attenuation and/or abatement of fabric
appearance loss.
The compositions of the present invention comprise a cationic polymer or co-
polymer which acts
together with a low molecular weight fabric enhancement polyamine, fabric
softness agent
(crystal growth inhibitor) and dye fixing agent to provide protection to
fabric from appearance
loss which is primarily due to mechanical loss. Another aspect of the present
invention relates to
a composition which comprises a cationic polymer or co-polymer which acts
together with a low
molecular weight fabric enhancement polyamine, fabric softness agent
(quaternary ammonium
fabric softener active), dye fixing agent, and one further enhancement agent,
inter al:a, a
stabilizer, co-solvent. Yet another aspect of the present invention relates to
a composition which
comprises a cationic polymer or co-polymer which acts together with a low
molecular weight

WO 00/56848 CA 02365282 2001-08-31 pCT~S00/08030
6
fabric enhancement polyamine, fabric softness agent (crystal growth inhibitor)
and quaternary
ammonium fabric softness agent, and dye fixing agent. The normal abrasive
destruction of the
fabric surface removes the surface layers of fabric which are dyed. Especially
in the case of
cotton fabric, below this layer of dyed fabric is the less dyed, then non-dyed
fabric. As wears a
"washed looked" develops which is due to the abrasive destruction of fabric
and the subsequent
loss of the weakened fabric fiber in the laundry cycle.
It has been surprisingly discovered that the combination of elements which
comprise the
compositions of the present invention modify the surface of fabric, especially
cellulosic fabric
and ameliorate many of the conditions which enhance fabric fiber surface wear
and subsequent
loss. The compositions of the present invention also soften the fabric surface
making the fibers
less abrasive and thereby reducing the level of friction between the fabric
and surfaces in which
the garment comes into contact. This change in surface condition can nullify
many of the
conditions which contribute to fabric damage and hence attenuate, and in some
cases, abate
fabric damage and therefore the concomitant loss of color.
The compositions of the present invention can be used for a stand alone
treatment of
fabric wherein the compositions are added as ingredients to a compatible fully
formulated rinsed
additive, laundry additive or pre-soak all of which are used together with
fabric softeners,
laundry detergent compositions and the like. The compositions of the present
invention, either as
a stand alone treatment or as a system, are suitable for providing a method
for treating fabric and
subsequently attenuating or abating the loss of color due to mechanical
abrasion and removal of
the top layer of dyed fabric.
Alternatively, the compositions comprise a fabric color integrity system. The
systems of
the present invention are used as an initial treatment of fabric by the
manufacturer of either the
fabric from which apparel is made or the fully formed article of manufacture
(apparel).
However, if the fabric is not pre-treated by the manufacturer, suitable
protection is afforded to
the fabric wherein the consumer applies the system to fabric during
laundering. The systems of
the present invention can be used at any point during the lifetime of apparel
to abate the loss of
color from fabric.
The following is a detailed description of the essential elements of the
present invention.
Cationic Polymer or Co-polymer
Compositions and systems of the present invention comprise from about 0.05%,
preferably for about 0.1 %, more preferably from about 0.5%, most preferably
from about 1 % to
about 10%, preferably to about 7%, more preferably to about S% by weight, of a
polymer, co-
polymer, or mixture thereof, wherein said polymer or co-polymer comprises at
least one

the suitability of a material for use as a crystal growth inhibitor.
Crystal Crrowth Inhibition Test 4CGIT)
The suitability of a material to serve as a crystal growth inhibitor according
to the present
invention can be determined by evaluating in vitro the growth rate of certain
inorganic micro-
crystals. The procedure of Nancollas et al., described in "Calcium Phosphate
Nucleation and
Growth in Solution", Prog. Crystal Growth Charact., Vol 3, 77-102, (1980),
is a method which is suitable for evaluating compounds for their crystal
growth
inhibition, The graph below serves as an example of a plot indicating the time
delay (t-lag) in
crystal formation afforded by a hypothetical crystal growth inhibitor.

The observed t-lag provides a measure of the compound's efficiency with
respect to delaying the
growth of calcium phosphate crystal. The greater the t-lag, the more efficient
the crystal growth
inhibitor.
Exemplary Procedure
Combine in a suitable vessel, 2,IM KCl (35 mL), O.OI75M CaCI, (50mL), O.O1M
KHZPO4 (SOmL), and de-ionized water (350mL). A standard pH electrode equipped
with a
Standard Calomel Reference electrode is inserted and the temperature adjusted
to 37° C while
purging of the solution of oxygen. Once the temperature and pH are stabilized,
a solution of the
crystal growth inhibitor to be test is then added. A typical inhibitor test
concentration is 1 x 10-~

CA 02365282 2004-08-06
21
M. The solution is titrated to pH 7.4 with 0.05M KOH. The mixture is then
treated with 5 mL's
of a hydroxyapatite slurry. The hydroxyapatite slurry can be prepared by
digesting Bio-Gel~
HTP hydroxyapatite powder (100 g) in 1 L of distilled water the pH of which is
adjusted to 2.5
by the addition of sufficient 6N HCl and subsequently heating the solution
until all of the
hydroxyapatite is dissolved (heating for several days may be necessary). The
temperature of the
solution is then maintained at about 22° C while the pH is adjusted to
12 by the addition of a
solution of 50% aqueous KOH. Once again the solution is heated and the
resulting slurry is
allowed to settle for two days before the supernatant is removed. 1.5 L of
distilled water is
added, the solution stirred, then after settling again for 2 days the
supernatant is removed. This
rinsing procedure is repeated six more time after which the pH of the solution
is adjusted to
neutrality using 2N HCI. The resulting slurry can be stored at 37°C for
eleven months.
Crystal growth inhibitors which are suitable for use in the present invention
have a t-lag
of at least 10 minutes, preferably at least 20 minutes, more preferably at
least 50 minutes, at a
concentration of 1 x IOM. Crystal growth inhibitors are differentiated form
chelating agents by
the fact that crystal growth inhibitors have a low binding affinity of heavy
metal ions, i.e.,
copper. For example, crystal growth inhibitors have an affinity for copper
ions in a solution of
0.1 ionic strength when measured at 25° C, of less than I5, preferably
less than 12.

Dye fixing agents, or "fixatives", are well-known, commercially available
materials
which are designed to improve the appearance of dyed fabrics by minimizing the
loss of dye
from fabrics due to washing. Not included within this definition are
components which can in
some embodiments serve as fabric softener actives.
Many dye fixing agents are cationic, and are based on quaternized nitrogen
compound or
on nitrogen compounds having a strong cationic charge which is formed in situ
under the
conditions of usage. Cationic fixatives are available under various trade
names from several
suppliers. Representative examples include: CROSCOLOR PMF (July 1981, Code No.
7894)
and CROSCOLOR NOFF (January 1988, Code No. 8544) ex Crosfield; INDOSOL E-50

REWIN
SRF-O and REWIN DWR ex CHT-Beitlich GMBH; Tinofix~ ECO, Tinofix~ FRD and
Solfin~
ex Ciba-Geigy. A preferred dye fixing agent for use in the compositions of the
present invention
is CARTAFIX CB~ ex Clariant.
Other cationic dye fixing agents are described in "Aftertreatments for
Improving the
Fastness of Dyes on Textile Fibres", Christopher C. Cook, Rev. Prog.
Coloration, Vol. XII,
(1982). Dye fixing agents suitable for use in the present invention are
ammonium compounds
such as fatty acid-diamine condensates inter alia the hydrochloride, acetate,

diaminotrimethylammonium methosulphate. In addition, the N-oxides of tertiary
amines;
derivatives of polymeric allcyldiamines, polyamine-cyanuric chloride
condensates, and aminated
glycerol dichlorohydrins are suitable for use as dye fixatives in the
compositions of the present
invention. A most preferred dye fixing agent comprises dodecyl
trimethylammonium chloride.
Cellulose Reactive Dve Fixing,Agents
Another dye fixing agent suitable for use in the present invention are
cellulose reactive
dye fixing agents. The compositions of the present invention optionally
comprise from about
0.01%, preferably from about 0.05%, more preferably from about 0.5% to about
SO°,io, preferably
to about 25%, more preferably to about 10% by weight, most preferably to about
5°/~ by weight,
of one or more cellulose reactive dye fixing agents. The cellulose reactive
dye fixatives may be
suitably combined with one or more dye fixatives described herein above in
order to comprise a
"dye fixative system".
The term "cellulose reactive dye fixing agent" is defined herein as "a dye
fixative agent
which reacts with the cellulose fibers upon application of heat or upon a heat
treatment either in

CA 02365282 2004-08-06
24
situ or by the formulator". The cellulose reactive dye fixing agents suitable
for use in the present
invention can be defined by the following test procedure.
Cellulose Reactivity Test (CRT)
Four pieces of fabric which are capable of bleeding their dye (e.g. 10 x 10 cm
of lalitted
cotton dyed with Direct Red 80) are selected. Two swatches are used as a first
control and a
second control, respectively. The two remaining swatches are soaked for 20
minutes in an
aqueous solution containing 1% (w/w) of the cellulose reactive dye fixing
agent to be tested. The
swatches are removed and thoroughly dried. One of the treated swatches which
has been
thoroughly dried, is passed ten times through an ironing calender which is
adjusted i:o a "linen
fabric" temperature setting. The first control swatch is also passed ten times
through an ironing
calender on the same temperature setting.
All four swatches ( the two control swatches and the two treated swatches, one
of each
TM
which has been treated by the ironing calender) are washed separately in
Launder-O-Meter pots
under typical conditions with a commercial detergent used at the recommended
dosage for '/2
hour at 60°C, followed by a thorough rinsing of 4 times 200 ml of cola
water and subsequently
line dried.
Color fastness is then measured by comparing the DE values of a new untreated
swatch
with the four swatches which have undergone the testing. DE values, the
computed color
difference, is defined in ASTM D2244. In general, DE values relate to the
magnitude and
direction of the difference beriveen two psychophysical color stimuli defined
by tristimulus
values, or by chromaticity coordinates and luminance factor, as computed by
means of a
specified set of color-difference equations defined in the CIE 1976 CIELAB
opponent-color
space, the Hunter opponent-color space, the Friele-Mac Adam-Chickering color
space or any
equivalent color space. For the purposes of the present invention, the lower
the DE value for a
sample, the closer the sample is to the un-tested sample and the greater the
color fastness benefit.
As the test relates to selection or a cellulose reactive dye fixing agent, if
the DE value for
the swatch treated in the ironing step has a value which is better than the
two control swatches,
the candidate is a cellulose reactive dye fixing agent for the purposes of the
invention.
Typically cellulose reactive dye fixing agents are compounds which contain a
cellulose
reactive moiety, non limiting examples of these compounds include halogeno-
triazincs, vinyl
sulphones, epichlorhydrine derivatives, hydroxyethylene urea derivatives.

is a fatty acyl moiety. Suitable fatty acyl moieties for use in the softener
actives of the present
invention are derived from sources of triglycerides including tallow,
vegetable oils and/or
partially hydrogenated vegetable oils including inter alia canola oil,
safflower oil, peanut oil,
sunflower oil, corn oil, soybean oil, tall oil, rice bran oil. Yet more
preferred are the Diester
Quaternary Ammonium Compounds (DEQA's) wherein the index m is equal to 2.
The formulator, depending upon the desired physical and performance properties
of the
final fabric softener active, can choose any of the above mentioned sources of
fatty acyl moieties,
or alternatively, the formulator can mix sources of triglyceride to form a
"customized blend".
However, those skilled in the art of fats and oils recognize that the fatty
acyl composition may
vary, as in the case of vegetable oil, from crop to crop, or from variety of
vegetable oil source to
variety of vegetable oil source. DEQA's which are prepared using fatty acids
derived from
natural sources are preferred.
A preferred embodiment of the present invention provides softener actives
comprising
R1 units which have at least about 3%, preferably at least about 5%, more
preferably at least
about 10%, most preferably at least about 15% C11-C22 alkenyl, including
polyalkenyl
(polyunsaturated) units inter alia oleic, linoleic, linolenic.
For the purposes of the present invention the term "mixed chain fatty acyl
units" is
defined as "a mixture of fatty acyl units comprising alkyl and alkenyl chains
having from 10
carbons to 22 carbon atoms including the carbonyl carbon atom, and in the case
of alkenyl
chains, from one to three double bonds, preferably all double bonds in the cis
configuration".
With regard to the R1 units of the present invention, it is preferred that at
least a substantial
percentage of the fatty acyl groups are unsaturated, e.g., from about 25%,
preferably from about
50% to about 70%, preferably to about 65%. The total level of fabric softening
active containing
polyunsaturated fatty acyl groups can be from about 3%, preferably from about
5%, more
preferably from about 10% to about 30%, preferably to about 25%, more
preferably to about
18%. As stated herein above cis and traps isomers can be used, preferably with
a cisltrans ratio
is of from 1:1, preferably at least 3: l, and more preferably from about 4:1
to about 50:1, more
preferably about 20:1, however, the minimum being 1:1.
The level of unsaturation contained within the tallow, canola, or other fatty
acyl unit
chain can be measured by the Iodine Value (IV) of the corresponding fatty
acid, which in the
present case should preferably be in the range of from 5 to 100 with two
categories of compounds
being distinguished, having a IV below or above 25.

WO 00/56848 CA 02365282 2001-08-31 PCT/[JS00/08030
28
Indeed, for compounds having the formula:
(R)4_m N-j-(CH2)p Q-R~ X
m
derived from tallow fatty acids, when the Iodine Value is from 5 to 25,
preferably 15 to 20, it has
been found that a cisltrans isomer weight ratio greater than about 30/70,
preferably greater than
about 50/50 and more preferably greater than about 70/30 provides optimal
concentrability.
For compounds of this type made from tallow fatty acids having a Iodine Value
of above
25, the ratio of cis to traps isomers has been found to be less critical
unless very high
concentrations are needed. A further preferred embodiment of the present
invention comprises
DEQA's wherein the average Iodine Value for R1 is approximately 45.
The R1 units suitable for use in the isotropic liquids present invention can
be further
characterized in that the Iodine Value (IV) of the parent fatty acid, said IV
is preferably from
about 10, more preferably from about 50, most preferably from about 70, to a
value of about 140,
preferably to about 130, more preferably to about 115. However, formulators,
depending upon
which embodiment of the present invention they choose to execute, may wish to
add an amount
of fatty acyl units which have Iodine Values outside the range listed herein
above. For example,
"hardened stock" (IV less than or equal to about 10) may be combined with the
source of fatty
acid admixture to adjust the properties of the final softener active.
A prefered source of fatty acyl units, especially fatty acyl units having
branching, for
example, "Guerbet branching", methyl, ethyl, etc. units substituted along the
primary alkyl chain,
synthetic sources of fatty acyl units are also suitable. For example, the
formulator may with to
add one or more fatty acyl units having a methyl branch at a "non-naturally
occuring" position,
for example, at the third carbon of a C 17 chain. What is meant herein by the
term "non-naturally
occuring" is "acyl units whihc are not found in significant (greater than
about 0.1%) quantities is
common fats and oils which serve as feedstocks for the source of triglycerides
described herein."
If the desired branched chain fatty acyl unit is unavailable from readily
available natural
feedstocks, therefore, synthetic fatty acid can be suitably admixed with other
synthetic materials
or with other natural triglyceride derived sources of acyl units.
The following are examples of preferred softener actives according to the
present
invention.

A preferred usage regime consists of the pre-treating the garment, or the
fabric from
which it is derived, with a composition according to the present invention.
'This pre-treatment
can be carned out by the manufacturer of the garment, or by the consumer. The
pre-treatment
can conveniently be carried out by the consumer during the pre-treatment or
primary wash cycle
of the domestic washing machine. In conjunction with the pre-treatment step
the consumer may
also use a co-composition as described herein which can suitably be added to
the rinse cycle of
the washing process. The co-composition can be optionally used every time that
the garment is
laundered. The compositions of the invention can be used to re-apply a pre-
treatment to the
garment on a periodic basis. The frequency of pre-applying the compositions of
the present
invention can be varied depending on the degree of color protection desired by
the consumer. A
typical re-application may commence after every 3 or 4 washing cycles to
maintain a good level
of color protection.
The following are non-limiting examples of the compositions of the present
invention.
