Description
FIELD OF THE DISCLOSURE
[0001] The present disclosure generally relates to methods of
removing color from color-treated or pre-dyed hair, as well as
compositions for use in removing color from color-treated or
pre-dyed hair, and more particularly using organic salts to remove
direct dyes from color-treated or pre-dyed hair.
BACKGROUND
[0002] The process of changing the color of hair can involve
depositing an artificial color onto the hair which provides a
different shade or color to the hair, and/or lifting the color of
the hair, such as lightening the color of dark hair to lighter
shades.
[0003] Imparting a color change or color effect on hair can be done
using permanent, semi-permanent, or temporary hair coloring
products. Semi-permanent dyeing uses direct dyes, which are
nonionic or ionic dyes and colored compounds capable of producing a
more or less pronounced change of the natural color of the hair.
These dyes may or may not be used in the presence of an oxidizing
agent. In contrast with oxidation dye precursors, a direct dye is a
relatively large molecule that does not penetrate easily into the
core of the fiber. Nevertheless, such dyes can be resistant to
shampoo-washing, even after several washes. Depending on a
consumer's goals, it may be desirable to either accelerate or slow
down the process of dye washout.
[0004] For example, some consumers desire to quickly change hair
colors. That is, they wish to dye the hair a particular color and
then change to another color before the first color has naturally
washed out, and thus must use a color removal product. Most color
removal products in the current cosmetic market are based on
destroying dyes placed in or on the hair by means of oxidative or
reductive reactions. However, those approaches have significant
drawbacks of damaging hair fibers. Thus, there is a desire to
provide ways to accelerate the removal of direct dyes from
color-treated hair, and particularly without damaging the hair.

carboxylates, phosphates, phosphate derivatives, tosylates,
tosylate derivatives, sulfates or sulfate derivatives,
[0150] an ammonium-based compound having a structure represented by
Formula (II) below:
##STR00020## [0151] wherein R1, R2, R3 and R4 are each
independently a saturated or unsaturated, linear, branched or

sulfates or sulfate derivatives, and
[0152] a combination thereof;
[0153] wherein the imidazolium-based compound and/or the
ammonium-based compound is in ionic liquid form.
[0154] As used herein, the term "pre-dyed with one or more direct
dye(s)" means the hair has been dyed with one or more direct dye(s)
prior to contact with the organic salt or composition containing
the organic salt.
[0155] As used herein, the term "ionic liquid" refers to the
organic salt of the present disclosure being in the liquid state or
having a melting point of equal to or under 150.degree. C.
(preferably 100.degree. C. or preferably less than 100.degree. C.),
or in some embodiments, at room temperature. Preferably, the salt
remains liquid up to 300 degrees centigrade, and more preferably
the salt is liquid at room temperature, that is to say, at a
melting point of less than or equal to 50 degrees centigrade and
greater than 0 degrees centigrade.
[0156] The melting point is measured by differential calorimetric
analysis, with a temperature increase rate of 10 degrees
centigrade/minute, the melting point then being at a temperature
corresponding to the top of the endothermic melting peak obtained
during the measurement.
[0157] According to the disclosure, the term "hydrophobic ionic
liquid" means an ionic liquid having a solubility in water at room
temperature (25 degrees centigrade) of less than 5 percent,
preferably less than 1 percent by weight, or even less than 0.5
percent. Within the context of the disclosure, the hydrophobic
character of the ionic liquid is such that there is phase
separation in water.
[0158] Within the context of the disclosure, the term
"water-soluble" means an organic salt or an ionic liquid which has
a solubility in water at 25 degrees centigrade of greater than 1
percent, preferably greater than 5 percent, more preferably greater
than 10 percent; that is to say, which forms at this concentration
a macroscopically homogeneous, transparent and isotropic
medium.
[0159] As used herein, the term "contacting" means that the
composition comes into contact with the hair so that the
composition is exposed to the surfaces of the hair which would
normally accommodate direct dye molecules or is exposed to the
direct dye molecules on the hair. It can also mean that the
composition is applied onto the hair. In some embodiments, this
means the hair can be soaked in the composition comprising organic
salt, or the composition is applied onto the hair by using the
hands or an applicator, or the hair may be mechanically manipulated
with the composition (e.g. using hands to manipulate hair in the
presence of the composition containing organic salt).
[0160] As used herein, the term "rinsing the hair" or "rinsing the
composition from the hair" means rinsing or washing the hair with
water, or shampooing the hair first, then rinsing the hair with
water.
[0161] It has been surprisingly discovered that such organic salts
are able to greatly accelerate and/or control the removal of direct
dyes from color-treated hair. While not wishing to be bound to any
particular theory, it is believed that the organic salts are able
to physically extract the direct dyes which reside on the surface
of hair fibers, as such dye molecules interact with hair protein by
non-covalent bonds. It is also believed that the physical
extraction of the dyes presents a mild approach to treating hair or
removing dyes from dyed hair without introducing harsh chemicals or
chemical reactions on hair that can damage or negatively impact the
integrity or quality of hair fibers. It is also thought that the
organic salts have a high swelling ability in hair fibers.
[0162] It has further been discovered that this acceleration can be
further enhanced by also including a surfactant in the process,
particularly for dyes which have a positive Log P.sub.ow value
and/or are hydrophobic. While not wishing to be bound by any
particular theory, it is thought the surfactants and organic salts
form binary surfactant systems and further enhance color removal by
increasing both hair wettability and dye solubility, and interact
with the dyes by ionic or hydrophobic interaction.

solvents.
[0187] In an embodiment, when the organic salt is contained in or
combined with a solvent such as water or one or more organic
solvents or a mixture of water and one or more organic solvents,
the organic salt dissociates into cations and anions in the solvent
(i.e., the organic salt is no longer in ionic liquid form).
[0188] In an embodiment, when the organic salt comprises an ionic
liquid and is contained in or combined with a solvent such as water
or one or more organic solvents or a mixture of water and one or
more organic solvents, a portion of the organic salt dissociates
into cations and anions in the solvent (i.e., the organic salt is
no longer in ionic liquid form) and a portion of the organic salt
remains an ionic liquid.
[0189] In one or more embodiments, the organic salts in the methods
and compositions of the present disclosure are advantageously used
on hair that has been dyed with direct dyes, in particular,
hydrophobic dyes and/or dyes which have a positive Log P.sub.ow
value, in order to accelerate color removal. Such hydrophobic dyes
interact with hair fibers through strong hydrophobic interactions,
and are thus difficult to be removed using general washing with
water or shampooing with conventional shampoos. In some
embodiments, the dyes advantageously removed using organic salts
contain an anthraquinone derivative and/or multi-aromatic rings,
and have low solubility in water.
[0190] In various embodiments, the organic salt may be present in
the composition at a concentration ranging from about 0.01, 0.1,
0.2, 0.3, 0.4, 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,
15, 16, 17, 19, 20, 25, 30, 35 or 40 to about 15, 16, 17, 19, 20,
25, 30, 35, 40, 45, 50, 55, 60, 65 or 70 wt. % by total weight of
the composition. In some embodiments pertaining to the use of
organic salts not in mixture with surfactant, the organic salt may
be present at a concentration ranging from about 1, 2, 3, 4, 5, 6,
7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 19, 20, 25, 30, 35 or 40
to about 15, 16, 17, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65 or
70 wt. % by total weight of the composition.
[0191] In other embodiments, the total amount of the organic salt
in the composition of the present disclosure is greater than 0.01
wt %, based on the total weight of the composition. In some cases,
the total amount of the organic salt in the composition ranges from
0.01 to about 70 wt. %, or from about 0.5 to about 65 wt. %, or
from about 1 to about 60 wt. %, or from about 1.5 to about 55 wt.
%, or from about 2 to about 50 wt. %, or from about 3 to about 35
wt. %, or from about 4 to about 30 wt. %, or from about 4.5 to
about 30 wt. %, or from about 5 to about 30 wt. %, or from about 5
to about 25 wt. %, based on the total weight of the composition,
including ranges and sub-ranges therebetween.
[0192] For example, when the organic salt is selected from
butyl-3-methylimidazolium octyl sulfate, butyl-3-methylimidazolium
acetate, ethyl-3-methylimidazolium ethylsulfate, 1-ethyl-3-ethyl
imidazolium acetate, 1-ethyl-3-methylimidazolium tosylate,
tributylmethyl ammonium chloride, and combinations thereof, the
total amount of organic salt in the composition may range from
greater than 0.5 to about 50 wt. %, or from about 2 to about 40 wt.
%, or from about 4 to about 35 wt. %, or from about 5 to about 30
wt. %, or from about 5 to about 25 wt. %, based on the total weight
of the composition, including ranges and sub-ranges
therebetween.
[0193] As a further example, when the organic salt is selected from
butyl-3-methylimidazolium octyl sulfate, butyl-3-methylimidazolium
acetate, ethyl-3-methylimidazolium ethylsulfate, 1-ethyl-3-ethyl
imidazolium acetate, 1-ethyl-3-methylimidazolium tosylate,
tributylmethyl ammonium chloride, and combinations thereof, the
total amount of the organic salt in the composition may be about 2,
3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
21, 22, 23, 24, 25, 26, 27, 28, 29, or 30 wt. %, based on the total
weight of the composition.
Surfactants
[0194] Compositions according to the disclosure comprise at least
one surfactant chosen from anionic, non-ionic, and/or
amphoteric/zwitterionic surfactants. Surfactants are advantageously
used in combination with the organic salts of the present
disclosure in order to further accelerate the removal of color from
or lighten the color of hair dyed with direct dyes (semi-permanent
color). If the surfactant has a very long hydrocarbon chain (i.e.,
more than 18-20 carbons), other emulsifiers may advantageously be
added. In exemplary embodiments, the direct dye used to color hair
has a positive Log P.sub.ow value and the compositions containing
at least one organic salt according to the present disclosure
further comprise an anionic and/or nonionic surfactant.

Methods
[0324] Compositions according to the disclosure can be used in
methods for removing color from hair, controlling the removal of
color from hair, and/or lightening the color of hair. It is to be
understood that "removing" color from hair encompasses any degree
or kind of color removal. Thus, "removing" color from hair includes
removing any amount (e.g. some or all) of color imparted by a
particular dye molecule(s) from the hair, or removing any amount
(e.g. some or all) of color imparted by one particular dye
molecule(s) from the hair regardless of whether any amount of color
imparted by another particular dye molecule remains in the hair.
Accordingly, it may be possible to completely or substantially
remove the color imparted to hair by one or more particular dye
molecules, control the removal of color imparted to hair by one or
more particular dye molecules, or lighten the color imparted to
hair by one or more particular dye molecules through various
combinations and amounts of components in the compositions
according to the disclosure.
[0325] In one or more embodiments, the organic salts may be used to
remove color imparted to the hair was imparted by one or more
direct dyes which is(are) either hydrophilic (e.g., cationic) or
hydrophobic dyes. In various embodiments, the one or more direct
dye(s) is(are) hydrophilic. In various embodiments, the one or more
direct dye(s) is(are) hydrophobic. In various embodiments, the
compositions are particularly useful for removing or controlling
the removal of semi-permanent hair color from hair fibers, or
lightening the color of hair pre-dyed with semi-permanent hair
color.
[0326] Methods according to the disclosure comprise contacting a
composition according to the disclosure with hair that has been
previously dyed, e.g. by one or more direct dyes, optionally
leaving the composition on the hair for a period of time, and
optionally rinsing the composition from the hair. In preferred
embodiments, the composition is rinsed from the hair with
water.
[0327] In various embodiments, e.g. where the composition is a
rinse-off hair treatment or mask or serum, the hair may be massaged
with the composition for a period of time and/or the composition
may be left on the hair for a period of time ("leave-in time") as
desired (e.g., 10, 20, 30 seconds or 1, 2, 3, 4, 5, 6, 7, 8, 9 or
10 minutes to 20, 30 seconds or 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or 15
minutes). Optionally, the hair may be heated while the composition
is in contact with the hair. For example, the hair may be heated at
a temperature ranging from about 25.degree. C. to about 60.degree.
C., such as with a hair dryer, e.g. a blow dryer or a hood dryer,
set at a temperature ranging from about 25.degree. C. to about
60.degree. C. The hair may be subsequently be rinsed.
[0328] Without being limited by theory, it is believed that the
combination of the organic salt and surfactant act together
synergistically to greatly improve the ease and speed of removing
direct dyes from the hair fibers. It is also believed that further
addition of the co-surfactant(s) and/or the cyclic compound(s), as
described herein, significantly boosts the ease and speed of
removing direct dyes from the hair fibers.
[0329] For example, the compositions described herein may be
particularly advantageous for removing azo direct dyes,
(poly)methine dyes such as cyanins, hemicyanins and styryls,
carbonyl dyes, azine dyes, nitro(hetero)aryl dyes,
tri(hetero)arylmethane dyes, porphyrin dyes, phthalocyanin dyes,
and natural direct dyes, alone or as mixtures. Without intending to
be limited, the following direct dyes are commonly used in
semi-permanent hair color, which the compositions according to the
disclosure are particularly useful for removing from hair fibers:

[0356] In various embodiments, the direct dye used to pre-color or

from non-ionic direct dyes, including hydrophobic direct dyes,
ionic direct dyes, including cationic direct dyes and anionic
direct dyes, and mixtures thereof.

[0358] In various embodiments, the direct dye used to pre-color or

[0359] In various embodiments, the direct dye used to pre-color or

used to pre-color or pre-dye the hair according to the present
disclosure is selected from cationic direct dyes. In yet further

[0361] Direct dyes may also be characterized by the partition
coefficient (Log P.sub.ow) values.
[0362] P.sub.ow is the octanol/water partition coefficient, which
can be defined as the ratio of the concentration of a solute, such
as the direct dye in the present disclosure, in a water-saturated
octanolic phase to its concentration in an octanol-saturated
aqueous phase. The octanol/water partition coefficient is typically
expressed in Logarithmic form.
[0363] There are several existing experimental methods by the
Organisation for Economic Co-operation and Development (OECD) and
Quantitative Structure-Property Relationship (QSPR) models
available for Log P.sub.ow measurement or prediction. The
experimental methods include: the `slow-stirring` method (OECD Test
No. 123), the high-performance liquid chromatography (HPLC) method
(OECD Test No. 117), and shake flask methods (referred to in OECD
Test No. 107).
[0364] Thus, partition coefficient of a dye may be calculated as
follows:
Log P.sub.ow=Log [(dye concentration in octanol)/(dye concentration
in water)].
[0365] The Log P.sub.ow value of a direct dye can be positive,
negative or neutral. The Log P.sub.ow values for some dyes follows

0.01 to about 50% wt. % of a surfactant selected from an anionic
surfactant, a nonionic surfactant, an amphoteric surfactant and
combinations thereof; [0413] iii. optionally, a co-surfactant; and
[0414] iv. optionally, a cyclic compound; and
[0415] b. rinsing the composition from the hair; [0416] wherein the

weights are based on the total weight of the composition.
[0420] In non-limiting exemplary embodiments, composition according
to the disclosure may be combined with other another composition,
e.g. a rinse-off hair shampoo or conditioner or mask. For example,
the composition may be added to a shampoo or conditioner or mask
composition, or the shampoo or conditioner or mask composition may
provide the at least one surfactant. In such embodiments, the
methods would include those steps customary in using shampoos
and/or conditioners and/or rinse-off masks or treatments. For
example, the hair may be massaged with the composition for a period
of time and/or the composition may be left on the hair for a period
of time ("leave-in time") as desired (e.g., 10, 20, 30 seconds or
1, 2, 3, 4, 5, 6, 7, 8, 9 or 10 minutes to 20, 30 seconds or 1, 2,
3, 4, 5, 6, 7, 8, 9, 10 or 15 minutes), and optionally heated. The
hair is then rinsed after each treatment.
EXAMPLES
[0421] The ingredient amounts in the composition/formulations
described below are expressed in % by weight, based on the total
weight of the composition, unless otherwise indicated.
Color Removal Examples
[0422] Several organic salts and surfactant combinations were
tested for efficacy for color removal of several direct dyes. The
organic salts tested are indicated in the table below.
TABLE-US-00003 Organic Salts Tested Name Structure
Butyl-3-methylimidazolium acetate (BMIM OAc) ##STR00037##
Ethyl-3-methylimidazolium ethylsulfate (EMIM ethylsulfate)
##STR00038## Tributylmethyl ammonium chloride (TBuMA Cl)
##STR00039##
[0423] Unless otherwise indicated, the formulations described
contained the active ingredients listed with the balance made up of
water.
[0424] Unless otherwise indicated, hair swatches were all treated
using the same protocol. Specifically, 2g dyed hair swatches were
soaked in 80 g treatment solutions or samples in water for 30
minutes at 40.degree. C., then the treated hair swatches were then
shampooed once and blow-dried for evaluation.
[0425] Unless otherwise indicated, color removal performance is
measured using CIE L*a*b* coordinates. .DELTA.E is used to describe
the color difference and is defined by the following equation:
.DELTA.E*.sub.ab= {square root over
((L*.sub.2-L*.sub.1).sup.2+(a*.sub.2-a*.sub.1).sup.2+(b*.sub.2-b*.sub.1).-
sup.2)}
where L1*, a.sub.1, b.sub.1 are measured on freshly dyed hair,
L*.sub.2, a.sub.2, b.sub.2 are measured on the dyed hair treated by
color remover systems. The higher .DELTA.E values, the more
efficient the color removal.

(SLES) at varying concentrations using the protocol described
above. The resulting .DELTA.E values are shown in the below table,
as well as in FIG. 1.
TABLE-US-00004 Concentration .DELTA.E of organic 0 wt. 3 wt. 6 wt.
12 wt. salts (wt. %) % SLES % SLES % SLES % SLES 0 9.06 21.08 21.81

8.6 39.0 -- --
[0427] As seen from FIG. 1 and the table above, the control sample
(with no organic salt or SLES) had a .DELTA.E of 9.06
(approximately 9.1). The results for increasing BMIM OAc
concentration alone are reproduced from above. SLES alone enhances
removal of dye, increasing the .DELTA.E to around 21-22.
Interestingly, increasing concentrations of SLES do not appear to
further increase the .DELTA.E. However, once the minimum
concentration of SLES is added to BMIM OAc, the .DELTA.E increases
well beyond the .DELTA.E for either component alone. This
demonstrates a synergistic effect of combining SLES with BMIM OAc.
Furthermore, the trend of increasing .DELTA.E with increasing BMIM
OAc concentration is accelerated when combined with just 3% SLES.
In addition, at about 1% of the organic salt, a significant change
in the .DELTA.E value compared to the control can already be
observed.
Example 2
Removal of HC Blue 15 Using EMIM Ethylsulfate and SLES
[0428] Hair swatches dyed with HC Blue 15 (Log P.sub.ow value
around 3.47) were treated with varying concentrations in water of
EMIM ethylsulfate and SLES at 3% concentration using the protocol
described above. The resulting .DELTA.E are shown in the below
table, as well as in FIG. 2.
TABLE-US-00005 Concentration of .DELTA.E organic salt (wt. %) 0 wt.
% SLES 3 wt. % SLES 0 9.1 21.1 1 2.7 30.0 5 2.1 32.3 10 1.5 33.5 25

[0429] As seen from FIG. 2 and the table above, the control sample
(with no organic salt or SLES) had a .DELTA.E of approximately 9.1.
The results for increasing EMIM ethylsulfate concentration alone
are reproduced from above. SLES alone enhances removal of dye,
increasing the .DELTA.E to around 21-22. As noted in the previous
example, increasing concentrations of SLES do not appear to further
increase the .DELTA.E. However, once the minimum concentration of
SLES (3%) is added to EMIM ethylsulfate, the .DELTA.E increases
well beyond the .DELTA.E for either component alone. This
demonstrates a synergistic effect of combining SLES with EMIM
ethylsulfate.
Example 3
Removal of Hydroxyanthraquinoneaminopropyl Methyl Morpholinium
Methosulfate Using BMIM OAc and SLES
[0430] Hair swatches dyed with hydroxyanthraquinoneaminopropyl
methyl morpholinium methosulfate (Log P.sub.ow value around 0.89)
were treated with BMIM OAc and/or SLES solutions using the protocol
described above except carried out at 23.degree. C. The resulting
.DELTA.E are shown in the below table, as well as in FIG. 3.
TABLE-US-00006 10% BMIM 10% BMIM OAc - 6% Treatment Water only OAc
6% SLES SLES .DELTA.E 2.9 7.5 18.2 38.7
[0431] As seen in FIG. 3 and the table above, the .DELTA.E value
significantly increases when dyed hair fibers are treated with a
mixture of 6% SLES and 10% BMIM OAc, indicating that adding BMIM
OAc to the SLES solution (6%) significantly boosts the color
removal efficacy of hydroxyanthraquinoneaminopropyl methyl
morpholinium methosulfate. In fact, the mixture greatly outperforms
either the BMIM OAc or SLES by itself, indicating a synergistic
effect.
Example 4
Removal of HC Blue 15 Using TBuMA Cl and SLES
[0432] Hair swatches dyed with HC Blue 15 (Log P.sub.ow value
around 3.47) were treated with TBuMA Cl and/or SLES using the
protocol described above. The resulting .DELTA.E are shown in the
below table, as well as in FIG. 4.
TABLE-US-00007 10% TBuMA Treatment Water only 6% SLES Cl - 6% SLES
.DELTA.E 3.0 21.4 46.2
[0433] As seen from FIG. 4 and the table above, the .DELTA.E value
of dyed hair fibers treated with the mixture of 10% TBuMA and 6%
SLES significantly increases, indicating that adding TBuMA to the
SLES solution significantly boosts efficiency of removing HC blue
15 from hair fibers. In addition, at 10% TBuMA HCl alone (without
SLES), when tested with removing HC Blue 15 from dyed hair, a
.DELTA.E value of 1.8 was obtained. Thus, the combination of TBuMA
and SLES also demonstrates a synergistic effect over the TBuMA and
SLES individually.
Example 5
Removal of HC Blue 15 Using BMIM OAc and Decyl-Glucoside
[0434] Hair swatches dyed with HC Blue 15 (Log P.sub.ow value
around 3.47) were treated with BMIM OAc and decyl-glucoside (DG) at
varying concentrations of 250 mM and 500 mM in water using the
protocol described above. The resulting .DELTA.E are shown in FIG.
5. For the mixture of DG and BMIM OAc, the concentration was 250 mM
(5 wt. % for BMIM OAc and 8% for DG) and 500 mM (10 wt. % for BMIM
OAC and 16% for DG) for each, to yield 500 mM and 1000 mM in
total.
[0435] As seen from FIG. 5, .DELTA.E value significantly increases
when dyed hair fibers are treated with a mixture of DG and BMIM
OAc, indicating that adding BMIM OAc to the SLES solution results
in a synergistic effect in the removal HC blue 15 from hair.
Example 6
Controlled Color Removal for Two-Tone Colored Hair (HC Blue 15 and
Basic Red 51) Treated With TBuMA Cl and SLES
[0436] Platinum bleached hair swatches were dyed with a commercial
hair dye with indigo shade, which contains a mixture of HC blue 15
(Log P.sub.ow value around 3.47) and Basic Red 51 (Log P.sub.ow
value around -1.97). 10% TBuMA Cl was added to a commercially
available shampoo containing about 9% SLES. The swatches were then
washed with either the shampoo alone (control) or shampoo with
TBuMA Cl and evaluated after one, three and six washes. Photographs
of the results are shown in FIG. 6.
[0437] Without addition of TBuMA Cl, the indigo color shifts to
green as the number of shampoos increased. This is because Basic
Red 51, a cationic direct dye, is washed out faster from hair by
washing with shampoo than the HC Blue 15. With addition of TBuMA Cl
to the shampoo, the leaching of Basic Red 51 is deterred or
inhibited and removal of HC Blue 15 is accelerated, thereby
resulting in the two dyes being removed at a more similar rate.
This results in the indigo color tone being maintained during
shampooing. These results show that the fading of color or removal
of color from hair that has been colored with direct dyes can be
controlled by using an anionic surfactant-containing composition
containing an organic salt such as a shampoo and the on-tone fading
of hair color can be maintained after several treatments or
shampooing/washing.
Example 6A
Color Removal Examples With the Addition of Co-Surfactants and
Cyclic Compounds
[0438] Treatment Protocol: Platinum bleached hair was dyed with a
commercial hair dye containing 0.2% HC blue 15 (Log P.sub.ow value
around 3.47). Dyed hair samples were then shampooed with a shampoo
containing SLES multiple times (4.times. for example 7 and 6.times.
for example 8 below) prior to the color removal soaking test. The
multiple shampooings/washings were designed to simulate the hair
cleansing activities in real life over a period of time or
weeks.
[0439] For the color removal test: taking hair from the
multiple-shampooed hair samples, 1 g dyed-shampooed hair swatches
were soaked in 40 g treatment solutions or samples as described
below for 30 minutes at 40.degree. C. The treated hair swatches
were rinsed under running tab water, then blow-dried for
evaluation.
[0440] Color removal performance is measured using CIE
L*a*b*coordinates and .DELTA.E is used to describe the color
difference as described above.
Example 7
Removal of HC Blue 15 Using BMIM OAc, SLES, and Ethanol
[0441] Hair swatches dyed with HC Blue 15 (Log P.sub.ow value
around 3.47) were treated with compositions containing TBuMA Cl,
sodium laureth sulfate (SLES), and ethanol, each alone or in
various combinations using the protocol described above. The
resulting .DELTA.E values are shown in the below table, as well as
in FIG. 7.
TABLE-US-00008 .DELTA.E 10%TBuMA Cl + 16% 6% 6% SLES + 16% EtOH
SLES 10% TBuMA Cl EtOH 1.77 19.3 3.63 50.3
[0442] As seen from FIG. 7 and the table above, the .DELTA.E values
for the dyed hair treated with the control samples (organic salt,
SLES, ethanol,) were significantly lower compared to the .DELTA.E
values for the dyed hair treated with the sample containing organic
salt, SLES, and ethanol (.DELTA.E of 50.3). The results also show
that the addition of ethanol boosted the color removal
efficacy.
Example 8
Removal of HC Blue 15 Using BMIM OAc, SLES, Ethanol, and Benzyl
Alcohol
[0443] Hair swatches dyed with HC Blue 15 (Log P.sub.ow value
around 3.47) were treated with aqueous compositions containing BMIM
OAc, sodium laureth sulfate (SLES), ethanol, and benzyl alcohol,
each alone or in various combinations using the protocol described
above. The resulting .DELTA.E values are shown in the below table,
as well as in FIG. 8.
TABLE-US-00009 .DELTA.E 10% BMIM OAc + 6% 10% BMIM SLES + 16% 10%
OAc + 6% EtOH + 10% 16% 6% 10% BMIM Benzyl SLES + 16% Benzyl EtOH
SLES OAc Alcohol EtOH Alcohol 1.8 15.01 7.13 9.4 48.5 54.9
[0444] As seen from FIG. 8 and the table above, the .DELTA.E values
for the dyed hair treated with the control samples (organic salt,
SLES, ethanol, benzyl alcohol) were significantly lower compared to
the .DELTA.E values for the dyed hair treated with the two samples
containing organic salt, SLES, ethanol and organic salt, SLES,
ethanol, and benzyl alcohol (.DELTA.E of 48.5 and 54.9). The
results also show that the addition of benzyl alcohol boosted the
color removal efficacy.
