Definitions
- This invention relates to a hair care composition that contains at least one hair care ingredient and at least one polymeric colorant.
- the first category is known as oxidative or permanent dye which is a form of pro-dye, which oxidizes during application to form color.
- oxidative or permanent dye which is a form of pro-dye, which oxidizes during application to form color.
- a few well-known examples in this class are phenylenediamines and para-aminophenol, which are blended with additional coupling agents (such as resorcinol, m-aminophenol, and the like).
- the other category is often referred as non-oxidative or direct dyes. These dyes are pre-formed dye molecules. Examples in this category include Basic Red 76, Acid Violet 43, HC Blue 15, and HC Blue 16.
- the current hair molecular dyes have drawbacks.
- the pre-formed dyes are conjugated, rigid organic compounds, and are often difficult to dissolve in the hair care compositions.
- the undissolved dyes can leave an uneven hue or sometimes color spots in treated hair.
- the toxicity of the hair dyes is also a concern.
- the current direct dyes tend to wash off very quickly and thus are considered semi-permanent.
- improvement over current hair dyes are continuously needed.
- polymeric liquid colorants are superior than conventional hair dyes for they are easier to formulate and have less toxicity concerns as their higher molecular weight makes them hard to penetrate skin. Polymeric liquid colorants also appear to have superior wash performance compared to current dyes.

- Polymeric colorants were also evaluated by the following procedure: Polymeric colorants were added to hair care compositions. Each sample was mixed using a SpeedMixer at 1500 rpm until a visually uniform mixture was obtained (SpeedMixer Inc., Landrum, S.C.). The colored hair care composition was transferred to a large weigh boat with the hair sample. A specific amount of the mixture was spread all over the hair and worked into the hair with fingertips until the mixture was fully incorporated evenly throughout the hair. The amount varied based on the type of hair care composition and is specified in each example. The colored hair care composition was allowed to sit on the hair for a specific amount of time and then the hair sample was rinsed thoroughly with lukewarm water, combed, and dried in the oven at 60° C. for 45 minutes.
- the amount of time varied based on the type of hair care composition and is specified in each example.
- the color of hair was measured using the X-Rite Color i7 with a 6 mm aperture.
- the result of each measurement was an L*, a*, b* value with a D-65, 10° observer basis.
- the hair was twisted tight and pressed to the aperture while taking the measurement.
- An average of 6-8 measurements was used.
- the primary means of comparing samples or evaluating the amount of color deposited onto the hair was ⁇ E which was calculated as described below and Yellowness Index (YI) which was calculated per ASTM Method E313.
- ⁇ E was used to indicate the efficiency of the polymeric colorant when dyeing hair.
- L*, a*, b* values were taken from the hair before coloring and after coloring.
- the changes in L*, a*, b*, ⁇ L*, ⁇ a*, ⁇ b*, were calculated and converted into ⁇ E values by the following equation:
- ⁇ E ⁇ square root over ( ⁇ L* 2 + ⁇ a* 2 + ⁇ b* 2 ) ⁇
- the higher ⁇ E values means greater hair color change before and after dyeing, and thus, more efficient hair colorants.
- Polymeric colorants of this invention were evaluated as semi-permanent hair colorants by coloring blonde hair swatches (bleached blonde from dark black).
- the blonde human hair swatches are commonly used to evaluate coloration by stylists and can be obtained from many different retailers.
- the hair care composition in this example was an uncolored semi-permanent hair coloring cream, Igora ColorWorx Dilutor (Schwarzkopf).

- the length of the polymer chains appears to affect deposition on the bleached hair (as example, compare Example 6 vs. 7, 12 vs. 13, 18 vs. 20, 28 vs. 29).
- the shorter polymer length tends to provide higher deposition.
- three different colorants with the same chromophore but with different polymer lengths were tested on yak belly hair.
- the hair care composition in this example was an uncolored semi-permanent hair coloring cream, Igora ColorWorx Dilutor (Schwarzkopf).
- the amount of color in the cream was adjusted so that each sample exhibited the same color strength, meaning the amount of chromophore or absorbance in each cream was the same despite the different polymer chain lengths. Similar to Application Example 1, the maximum absorbance of the colored cream was 0.1 when measured with 1 cm path length at concentration of 1 grams/liter in methanol.
- yak belly hair was used as the hair substrate and the hair was colored using the procedure above.
- the amount of cream used was 2 grams of cream per gram of hair.
- the cream was contacted with the hair 20 minutes before rinsing off.
- the ⁇ E value for the colored vs. the uncolored hair was used. The results are shown in Table 4.
- the amount of color deposited decreases as the polymer chain length increases. As the number of EO units increase, the amount of deposition tends to decrease. The results indicate that 5 to 6 EO units is optimal.
- Polymeric colorants of this invention were compared to current commercial hair dyes by coloring blonde hair (bleached blonde from dark black).
- a red colorant (Example 16) was put into Igora ColorWorx diluter cream at 1.5 wt % and compared to current commercial product Igora ColorWorx Red cream which contained the dyes 4-hydroxypropylamino-3-nitrophenol and 3-nitro-p-hydroxyethylaminophenol.
- a yellow colorant (Example 35) was similarly put into Igora ColorWorx diluter cream at 1.5 wt % and compared to current commercial product Igora ColorWorx Yellow cream which contained the dyes HC Yellow No. 13 and HC Yellow No. 2.

- the amount of cream used was 2 grams of cream per gram of hair.
- the cream was contacted with the hair 20 minutes before rinsing off.
- the L*a*b* color of the hair was then measured as outlined above.
- the hair was then washed using Schauma 7 Herbs Shampoo (Schwarzkopf) and dried with a hair dryer using the procedure below.
- the hair was fully wet using 40° C. tap water.
- Shampoo 0.2 grams of shampoo per 1 gram of hair was then added to the hair and worked in using fingers for 30 seconds.
- the hair and shampoo were allowed to sit in a dish for another 30 seconds and then rinsed for 30 seconds using 40° C. tap water.
- the hair sample was then dried using a hair dryer.
- the hair was washed and dried twice and then its L*a*b* color was measured. The hair was then washed and dried two more times and measured again.
- the ⁇ E value for the colored at any particular wash state vs. the uncolored hair was used.
- the retained hair color after two and four washes was evaluated by dividing the ⁇ E value of the washed hair by the ⁇ E value of the unwashed, initially deposited hair color. Higher values indicated better retention of hair color during the wash, with a value of 100% meaning no color loss.
- Polymeric colorants like conventional hair dyes, can be used widely in a variety of different hair coloring formulations. This was demonstrated by taking a single polymeric colorant (Example 10) and mixing it into several different commercial uncolored semi-permanent hair coloring creams at 0.16% by mass and applied to bleached blonde hair. The amount of cream used was 1 grams of cream per gram of hair. The cream was contacted with the hair 20 minutes before rinsing off. The amount of color deposited onto the hair was evaluated by measure ⁇ E of the colored hair relative to the uncolored hair and is shown in Table 6.

- the polymeric colorant is highly effective in all the evaluated creams which demonstrates these materials will work in a wide range of different formulations, each with a wide variety of ingredients.
- Shampoo is a commonly used hair care composition that can also be used to deposit color onto hair.
- a range of polymeric colorants can be used to color hair in a shampoo formulation.
- the hair care composition in this example was a shampoo, BC Bonacure pH 4.5 Color Freeze Micellar Rich Shampoo (Schwarzkopf). For each colorant, the amount of colorant in the shampoo was adjusted so that each sample exhibited the same color strength, meaning the amount of chromophore or absorbance in each shampoo was the same despite the different polymer chain lengths and chromophore types.
- the maximum absorbance of the colored shampoo was 0.25 when measured with 1 cm path length at concentration of 1 grams/liter in methanol.
- bleached blonde hair was used as the hair substrate and the hair was colored using the procedure above.
- the amount of shampoo used was 0.2 grams of shampoo per gram of hair.
- the shampoo was contacted with the hair 3 minutes before rinsing off.
- the ⁇ E value for the post shampoo vs. the pre-shampoo hair was used.
- the Yellowness Index (YI) was calculated for the post shampoo and the pre-shampoo hair samples and the change in YI ( ⁇ YI) from shampoo treatment calculated.
- YI Yellowness Index
- ⁇ YI change in YI
- a major application of the dyes in shampoo is to neutralize this warm tone to a cooler or more white tone.
- ⁇ YI of the hair By evaluating the ⁇ YI of the hair, one can observe the desired effect of toning or neutralizing the undesired warm tone. The more the YI decreases, the less yellow or brassy the hair appears; in other words, the more negative the ⁇ YI of the shampoo treatment, the better the colorant covers the undesired yellow tone.
- the shade of the polymeric colorant is appropriate to neutralize the yellow tones of the hair (such as Example 10 and Example 11), the ⁇ YI is more strongly negative than comparative dye, implying that they are more effective at neutralizing yellow tones.
- Some colorants are not the desired shade to neutralize yellow tones in bleached hair, such as Example 30, but can be used for other colorations such as yellow, red, pink, etc.
- the shampoo was BC Bonacure pH 4.5 Color Freeze Micellar Rich Shampoo (Schwarzkopf).
- the amount of colorant in the shampoo was adjusted so that each sample exhibited the same color strength; the maximum absorbance of the colored shampoo was 0.043 when measured with 1 cm path length at concentration of 1 grams/liter in methanol. This is a colorant loading level similar to many commercial toning shampoos. Bleached blonde hair was used as the hair substrate. The amount of shampoo used was 0.2 grams of shampoo per gram of hair. The shampoo was contacted with the hair 3 minutes before rinsing off. To evaluate the amount of color deposited onto the hair in each wash, the ⁇ E value for the hair after vs. before each shampoo wash was used.
- Results are shown in Table 8.
- the polymeric colorant deposits more in the first wash than the dye. Both the dye and polymeric colorant show lower deposition in the second and third wash then the first wash. Surprisingly, the polymeric colorant shows ever decreasing deposition with increasing washes past the third wash which indicates leveling while the dye shows a steady amount of deposition past the third wash which indicates continued building of the dye onto the hair.
- the polymeric colorant in this case shows a desirable behavior: strong initial deposition followed by rapid leveling. This would allow a consumer to observe a clear effect after only one or two washes but safely continue using the shampoo with reduced concern of over-toning or undesirably violet or blue coloring.

Abstract
This invention relates to a hair care composition that contains at least one hair care ingredient and at least one polymeric colorant.
Description
- This application claims priority to U.S. Provisional Patent Application No. 63/077,737, entitled “Hair Care Composition Containing Polymeric Colorant,” which was filed on Sep. 14, 2020, and is entirely incorporated by reference herein.
- This invention relates to a hair care composition that contains at least one hair care ingredient and at least one polymeric colorant.
- Various hair dyes have been invented as consumers desire to color their hair. Typically, there are two category of hair dyes. The first category is known as oxidative or permanent dye which is a form of pro-dye, which oxidizes during application to form color. A few well-known examples in this class are phenylenediamines and para-aminophenol, which are blended with additional coupling agents (such as resorcinol, m-aminophenol, and the like). The other category is often referred as non-oxidative or direct dyes. These dyes are pre-formed dye molecules. Examples in this category include Basic Red 76, Acid Violet 43, HC Blue 15, and HC Blue 16.
- However, the current hair molecular dyes have drawbacks. The pre-formed dyes are conjugated, rigid organic compounds, and are often difficult to dissolve in the hair care compositions. The undissolved dyes can leave an uneven hue or sometimes color spots in treated hair. In addition, the toxicity of the hair dyes is also a concern. Additionally, the current direct dyes tend to wash off very quickly and thus are considered semi-permanent. Thus, improvement over current hair dyes are continuously needed. In this aspect, polymeric liquid colorants are superior than conventional hair dyes for they are easier to formulate and have less toxicity concerns as their higher molecular weight makes them hard to penetrate skin. Polymeric liquid colorants also appear to have superior wash performance compared to current dyes.

Alkoxylated alcohols, or ethers, are formed by the reaction of an alcohol with an alkylene oxide, usually ethylene or propylene oxide. Preferably the alcohol is a fatty alcohol having 6 to 30 carbon atoms, and a straight or branched, saturated or unsaturated carbon chain. Examples of such ingredients include steareth 2-30, which is formed by the reaction of stearyl alcohol and ethylene oxide where the number of repeating ethylene oxide units is 2 to 30; laureth 2-30, which is formed by the reaction of lauryl alcohol and ethylene oxide where the number of repeating ethylene oxide units is 2 to 30; Oleth 2-30 which is formed by the reaction of oleyl alcohol and ethylene oxide where the number of repeating ethylene oxide units is 2 to 30; Ceteareth 2-100, formed by the reaction of a mixture of cetyl and stearyl alcohol with ethylene oxide, where the number of repeating ethylene oxide units in the molecule is 2 to 100; Ceteth 1-45 which is formed by the reaction of cetyl alcohol and ethylene oxide, and the number of repeating ethylene oxide units is 1 to 45, and so on.

The term “poly(alkyleneoxy) substituted chromophore colorant” generally refers to a colorant having at least one chromophore portion attached to at least one oligomeric or polymeric poly(alkyleneoxy) chain, wherein the chain has at least two repeating units, and preferably at least three repeating units. The oligomeric or polymeric substituent can be bound to the chromophore portion via any suitable means, such as a covalent bond, an ionic bond, or suitable electrostatic interaction. Generally, the polymeric colorant may be characterized by having an absorbance in the range of between about 300 nanometers and about 900 nanometers, as measured by UV-vis spectroscopy. In one aspect of the invention, the polymeric colorant has a maximum absorbance in the range from 400 nanometers to 700 nanometers.
- As a function of its manufacturing process, the polymeric colorant has a molecular weight that is typically represented as a molecular weight distribution. Accordingly, the molecular weight of the polymeric colorant is generally reported as an average molecular weight, as determined by its molecular weight distribution.
- The chromophore portion of the polymeric colorant may vary widely and may include compounds characterized in the art as dyestuffs or as pigments. The actual group used will depend to a large extent upon, for instance, the desired color, colorfastness, and stability characteristics. The chromophore portion may be attached to at least one polyalkyleneoxy-substituent through a suitable linking moiety of nitrogen, oxygen, sulfur, etc.
- In one aspect, the polymeric colorant be a neutral or an uncharged molecule. In a further aspect, the polymeric colorant may be nonionic, anionic, or cationic. The polymeric colorant may contain a chromophore group that has both positive and negative charges. Further, the polymeric colorant may be zwitterionic or amphoteric.

- Typical of such groups which may be attached to the chromophore group are the polymeric epoxide groups, such as the polyalkylene oxide groups and copolymer groups thereof. Typical polyalkylene oxides and copolymers of same which may be employed to provide the colorants include those made from alkylene oxide monomers containing from two to twenty carbon atoms, or more preferably, from two to six carbon atoms. Examples include: polyethylene oxides; polypropylene oxides; polybutylene oxides; oxetanes; tetrahydrafurans; copolymers of polyethylene oxides, polypropylene oxides and polybutylene oxides; and other copolymers including block copolymers, in which a majority of the polymeric substituent is polyethylene oxide, polypropylene oxide and/or polybutylene oxide. Further, such polyalkyleneoxy group may have an average molecular weight in the range of from about 132 to about 10,000, preferably from about 176 to about 5000.
- It is to be understood that because the colorants may or may not be chemically bound to ingredients comprising the hair care composition, the precise chemical identity of the end group on the polyalkyleneoxy group may not be critical insofar as the proper functioning of the colorant is concerned in the composition. With this consideration in mind, certain most preferred colorants will be defined wherein certain end groups will be identified. Such recitation of end groups is not to be construed as limiting the invention in its broader embodiments in any way. According to such a most preferred embodiment the colorants may be characterized as follows:
-

- wherein R2 is H, an alkyl radical containing up to about 20 carbon atoms or carboxy-terminated alkyl radical containing up to about 20 carbon atoms, j and k are OH, OM or OR3 wherein M is a cation moiety of an alkali metal, an alkaline earth metal, transition metal, e.g., nickel, etc. or ammonium, and R3 is an alkyl radical containing up to about 20 carbon atoms, and R4 is selected from —CH2—, —CH2CH2—, CH2CH2CH2—, —CH2CH2CH2CH2—, —CH2CH(CH3)—, —CH2CH(CH2CH3)—, CH2CH2CH(CH3)—, CH2CH(OR1)(CH2)—
- The oligomeric constituent can be any suitable constituent including, but not limited to, oligomeric constituents selected from the group consisting of (i) oligomers comprising at least two monomers, or repeating units, selected from the group consisting of C2-C20 alkyleneoxy groups, glycidol groups, and glycidyl groups, (ii) aromatic or aliphatic oligomeric esters conforming to structure (I):
- and (iii) combinations of (i) and (ii). In structure (I), R2 and R3 are independently selected from the group consisting of hydrogen and C1-C10 alkyl groups, f is an integer between and including 1 and 10, and g is any positive integer or fraction between and including 1 and 20. As will be understood by those of ordinary skill in the art, suitable values for g include both integers and fractions because the length of the oligomeric constituent on the individual polymeric colorant molecules may vary. Thus, the value for g represents an average length of the ester chain for a given sample or collection of polymeric colorant molecules. In certain embodiments, the polymeric colorant can comprise one or more oligomeric constituents consisting of two or more ethylene oxide monomer groups.
- The polymeric colorant may be alkoxylated. Alkoxylation is carried out by procedures well-known to those skilled in the art (see, for example, U.S. Pat. Nos. 4,137,243; 5,082,938; 5,135,972; 5,591,833; 6,593,483; 7,587,857; 9,056,963; and 9,068,081).
- Exemplary polymeric colorants include Liquitint® polymeric colorants, Cleartint® polymeric liquid concentrate colorants, Reactint® polymeric colorants, and Palmer® polymeric colorants, all of which are available from Milliken Chemical, a division of Milliken & Company of Spartanburg, S.C. Liquitint® polymeric colorants are characterized in that they are water soluble, non-staining, colorants. They are widely used in laundry detergents, fabric softeners, and other consumer and industrial cleaning products. Liquitint® polymeric colorants are generally bright liquid colorants which, depending on the specific colorant, exhibit varying degrees of solubility in water. These colorants may also be characterized as being generally compatible with other chemicals present in their end-use formulations and are typically easy to handle. Liquitint® polymeric colorants may be used to provide color in both aqueous and solid systems. The unique polymeric nature of Liquitint® polymeric colorants provides reduced staining to skin, textiles, hard surfaces, equipment, and the like.
- Reactint® polymeric colorants are liquid polymeric colorants useful for coloring polyurethane and other thermoset resins. These colorants are reactive polymeric colorants that consist of chromophores which are chemically bound to polyols. This arrangement allows the polymeric colorant to react into the polyurethane polymer matrix. Unlike pigment pastes, which are dispersions of solid particles in a liquid, Reactint® polymeric colorants are 100% homogeneous liquids that are soluble in polyol and will not settle over time. Because of this pure liquid and easy to disperse nature, it is possible to blend Reactint® colorants in-line and on-the-fly, while producing polyurethane foams and resins.
- Palmer® polymer colorants are liquid colorants specially developed for use in washable applications, such as in markers, paints and other art products. They contain no heavy metals, are non-toxic, and have excellent non-staining properties on skin, fabric and other surfaces. Palmer® polymeric colorants have very good compatibility with aqueous ink formulations and provide bright colors.

- In one aspect of the invention, the colorant is a thiophene azo colorant according to the following structure:
- wherein each x and y are independently integers from 0 to 20.
- It is also contemplated to be within the scope of the present invention that other colorants may be combined with the polymeric colorant to form the coloring agent portion of the hair care composition. For example, a colorant selected from one or more of the following classes may be suitable: acid dyes, basic dyes, direct dyes, solvent dyes, vat dyes, mordant dyes, indigoid dyes, reactive dyes, disperse dyes, sulfur dyes, fluorescent dyes; pigments, both organic and inorganic; natural colorants; and the like. Thus, the coloring agent of the hair care composition may be comprised of a blend or mixture of a polymeric colorant and a non-polymeric colorant. The polymeric colorant and the non-polymeric colorant may have the same chromophore groups, or they may have different chromophore groups.
- The hair care composition of the present invention is prepared by combining at least one hair care ingredient with at least one polymeric colorant. The hair care composition thus formed may be a substantially homogenous mixture.
- A method for preparing the hair care composition of the present invention is comprised of the following steps:
-
- (a) providing at least one hair care ingredient;
- (b) providing at least one polymeric colorant; and
- (c) combining the at least one hair care ingredient and the at least one polymeric colorant to form a polymeric colorant-containing hair care composition.
- A method for applying color to hair according to the present invention is comprised of the following steps:
-
- (a) providing a polymeric colorant-containing hair care composition;
- (b) applying the polymeric colorant-containing hair care composition to hair;
- (c) allowing the polymeric colorant-containing hair care composition to contact the hair for a period of time; and
- (d) optionally, removing the polymeric colorant-containing hair care composition from the hair.
- A method for bleaching and applying color to hair according to the present invention is comprised of the following steps:
-
- (a) providing a polymeric colorant-containing hair care composition, wherein the composition further comprises an oxidizing agent;
- (b) applying the composition to hair;
- (c) allowing the composition to contact the hair for a period of time; and
- (d) optionally, removing the composition from the hair.
- The hair care composition may be allowed to contact the hair for a period of time in the range from 10 seconds to 1 hour, or in the range from 30 seconds to 45 minutes, or in the range from 1 minute to 30 minutes, or in the range from 3 minutes to 15 minutes. The hair may be wet with water prior to application of the hair care composition, or the hair may be dry when it is applied to the hair.
- The hair care composition may be permanent (e.g. 80% of original color intensity is still visible after 20 wash cycles), semi-permanent (e.g. 80% of original color intensity is visible up to, but not subsequent to, 20 wash cycles), or temporary (e.g. 80% of original color intensity is visible up to, but not subsequent to, 5 wash cycles). The permanence of the hair color on the hair may depend on the specific polymeric colorant included in the composition and/or the amount of polymeric colorant included in the composition. For example, increasing the amount of polymeric colorant in the hair care composition may result in the color lasting longer on the hair. In contrast, including less polymeric colorant in the composition may result in the color lasting less time on the hair. Also, the amount of time the hair care composition remains in contact with the hair during the coloring process may affect amount of color, depth of color and/or shade, and the permanence of the hair color on the hair. For instance, leaving the composition on the hair for a longer period of time during the hair coloring process may result in a greater depth of shade and/or color and color that lasts longer on the hair.
- In one aspect of the invention, the amount of polymeric colorant in the hair cream is in the range from 0.0001%-10%, or in the range from 0.1%-5%.
- In one aspect of the invention, the molecular weight of polymeric colorant in the hair cream is in the range from 100-10000 Dalton or in the range from 200-5000 Dalton or in the range from 300 to 2000 Dalton.
- At least one polymeric colorant as described herein may be added to a hair care composition for use in coloring hair. As a result, the invention also encompasses hair (or a keratin-containing material) containing at least one polymeric colorant. The invention further encompasses a process for bleaching and/or coloring hair (or a keratin-containing material) that includes the steps of providing hair, applying and/or depositing a hair care composition as described herein to the hair, allowing the composition to contact the hair for a period of time, and further agitating, rinsing, and/or drying the thus treated hair.
- For application in non-oxidative systems, there is typically a single component which is often a cream (but not limited to such) which contains hair care ingredients listed previously and the color mixed together. The single component cream is put on the hair and the color deposits directly on the hair. The colored cream is then washed off, leaving colorant on the hair.
- For application in oxidative systems, there are typically two components. One component contains an oxidative species (such as hydrogen peroxide). The second component contains other species, typically designed to raise pH, but could also contain other oxidative species such as persulfates. In one aspect of the invention, the two components are mixed together before applying to hair. The initial application includes the polymeric colorant in the hydrogen peroxide cream, not in the second component. However, it is conceivable to put the polymeric colorant in the second component instead.
- Thus, in one embodiment, at least one polymeric colorant is mixed into an oxidizer containing cream. Immediately before use, the polymeric colorant/hydrogen peroxide containing cream is mixed with at least one other component that raises the pH a sufficient amount to activate the hydrogen peroxide. In an alternative embodiment, the polymeric colorant may be added to the second component. In this instance, the second component is added to the uncolored hydrogen peroxide cream immediately before use.
- While the invention described herein has been directed mainly to hair care compositions containing polymeric colorants, it is not limited to only those compositions. The composition may contain a combination of polymeric colorant and another coloring agent. Other coloring agents include, for example, dyes, pigments, and combinations thereof.
- Suitable dyes include small molecule dyes. Suitable small molecule dyes include small molecule dyes selected from the group consisting of dyes falling into the Colour Index (C.I.) classifications of Direct Blue, Direct Red, Direct Violet, Acid Blue, Acid Red, Acid Violet, Basic Blue, Basic Violet and Basic Red, or mixtures thereof. Examples of small molecule dyes include those selected from the group consisting of Colour Index (Society of Dyers and Colourists, Bradford, UK) numbers Direct Violet 9, Direct Violet 35, Direct Violet 48, Direct Violet 51, Direct Violet 66, Direct Violet 99, Direct Blue 1, Direct Blue 71, Direct Blue 80, Direct Blue 279, Acid Red 17, Acid Red 73, Acid Red 88, Acid Red 150, Acid Violet 15, Acid Violet 17, Acid Violet 24, Acid Violet 43, Acid Red 52, Acid Violet 49,

- Suitable pigments include pigments selected from the group consisting of flavanthrone, indanthrone, chlorinated indanthrone containing from 1 to 4 chlorine atoms, pyranthrone, dichloropyranthrone, monobromodichloropyranthrone, dibromodichloropyranthrone, tetrabromopyranthrone, perylene-3,4,9,10-tetracarboxylic acid diimide, wherein the imide groups may be unsubstituted or substituted by C1-C3 -alkyl or a phenyl or heterocyclic radical, and wherein the phenyl and heterocyclic radicals may additionally carry substituents which do not confer solubility in water, anthrapyrimidinecarboxylic acid amides, violanthrone, isoviolanthrone, dioxazine pigments, copper phthalocyanine which may contain up to 2 chlorine atoms per molecule, polychloro-copper phthalocyanine or polybromochloro-copper phthalocyanine containing up to 14 bromine atoms per molecule and mixtures thereof.
- In one aspect of the invention, the components of the hair care composition may be prepared by combining the components in any convenient order and by mixing, e.g., agitating, the resulting component combination to form a phase stable semi-liquid (i.e. cream) composition. In another process for preparing such compositions, a liquid matrix is formed containing at least a major proportion, and preferably substantially all, of the liquid components, with the liquid components being thoroughly admixed by imparting shear agitation to this liquid combination. For example, rapid stirring with a mechanical stirrer may usefully be employed. While shear agitation is maintained, substantially all of any solid form ingredients can be added. Agitation of the mixture is continued, and if necessary, can be increased at this point to form a solution or a uniform dispersion of insoluble solid phase particulates within the liquid phase. As a variation of the composition preparation procedure hereinbefore described, one or more of the solid components may be added to the agitated mixture as a solution or slurry of particles premixed with a minor portion of one or more of the liquid components. After addition of all of the composition components, agitation of the mixture is continued for a period of time sufficient to form compositions having the requisite viscosity and phase stability characteristics. Frequently this will involve agitation for a period of from about 30 to 60 minutes.
- The hair care composition of the present invention may be combined with other molecules, compounds, and/or agents useful for applying the composition to hair and/or for enhancing color performance. Other molecules, compounds and/or agents include, for example, surfactants, solvents, preservatives, antimicrobial agents, antibacterial agents, perfumes, and the like, and combinations thereof.
- The hair care compositions of the present invention may also include any number of additional optional ingredients. These include conventional hair colorant composition components such as emollient oils, surfactants which may include nonionic, anionic, cationic, zwitterionic, betaine surfactants, polar solvents, chelating agents, pH adjusters, conditioning agents, and other ingredients. The various optional hair cream composition ingredients, if present in the compositions herein, should be utilized at concentrations conventionally employed to bring about their desired contribution to the composition and/or coloring process. Frequently, the total amount of such optional hair cream composition ingredients can range from about 0.01% to about 50%, more preferably from about 0.1% to about 30%, by weight of the composition.
- The following polymeric colorants were made and evaluated in a variety of different hair care compositions:

As these materials are polymeric, there exists a distribution around the mean number of repeat units; for the materials listed in the table above, the mean value of repeat units is listed.
- To prepare the hair care composition containing a polymeric colorant, the polymeric colorant may be mixed with the hair color or the colorant may be added to an already made hair care composition. For example, the following hair care composition according to the invention can be prepared:
- Hair Cream Formulations 1 to 3

The homogenizer mill is then turned on and the veegum sprinkled into the beaker. The mixture is milled for 15 minutes. While maintaining the temperature, ethoxy diglycol, disodium EDTA, erythorbic acid and methylparaben are added to the mixture, which is further milled for about 15 minutes. In a separate beaker the aminomethylpropanol, monoethanolamine, and water are combined, then this mixture is added to the mixture of other ingredients. The batch is transferred to a turbine/sweep kettle.
- Separately, the oil ingredientsoleic acid, cetearyl alcohol, emulsifying wax, oleth-20, oleyl alcohol, and Steareth 21are combined and heated to 70-75° C. The oil phase is then combined with the other ingredients and mixed well while maintaining the temperature at 70-75° C. The batch was cooled to 35-40° C. The fragrance oil and color are added, and the composition is mixed for an additional 15 minutes. The batch is cooled to 25° C.
- Alternatively, hair care compositions according to the invention can prepared by mixing the above polymeric colorant examples with commercially available hair care compositions. These hair care compositions may include semi-permanent hair coloring cream. Such examples may include Igora ColorWorx Dilutor (Schwarzkopf), Colorista Clear Mixer (L'Oreal), Color Charm Paints Clear (Wella), and Color Fresh Create Tomorrow Clear (Wella). These hair care compositions may also include shampoo. Such examples may include After Color Treatment Shampoo (Fanola), Tresemme Pro Pure Micellar Moisture Shampoo (Unilever), Pantene Nutrient Blends Illuminating Color Care Shampoo (P&G), BC Bonacure pH 4.5 Color Freeze Micellar Rich Shampoo (Schwarzkopf), Free & Clear Shampoo for Sensitive Skin (Pharmaceutical Specialties, Inc.), EverPure Blonde Shampoo (L'Oreal), and Schauma 7 Herbs Shampoo (Schwarzkopf). These hair care compositions may also include conditioner, deep conditioner, and conditioning masks. Such examples may include EverPure Blonde Conditioner (L′Oreal), Pantene Nutrient Blends Illuminating Color Care Conditioner (P&G), Pantene Pro-V Classic Clean Conditioner (P&G), Nutri Care Restructuring Conditioner (Fanola), Schauma 7 Herbs Conditioner (Schwarzkopf). These hair care compositions may also include a variety of leave-in products such as leave-in conditioner, hair spray, mousse, gel, wax, etc.
- Polymeric colorants were also evaluated by the following procedure: Polymeric colorants were added to hair care compositions. Each sample was mixed using a SpeedMixer at 1500 rpm until a visually uniform mixture was obtained (SpeedMixer Inc., Landrum, S.C.). The colored hair care composition was transferred to a large weigh boat with the hair sample. A specific amount of the mixture was spread all over the hair and worked into the hair with fingertips until the mixture was fully incorporated evenly throughout the hair. The amount varied based on the type of hair care composition and is specified in each example. The colored hair care composition was allowed to sit on the hair for a specific amount of time and then the hair sample was rinsed thoroughly with lukewarm water, combed, and dried in the oven at 60° C. for 45 minutes. The amount of time varied based on the type of hair care composition and is specified in each example. The color of hair was measured using the X-Rite Color i7 with a 6 mm aperture. The result of each measurement was an L*, a*, b* value with a D-65, 10° observer basis. The hair was twisted tight and pressed to the aperture while taking the measurement. An average of 6-8 measurements was used. The primary means of comparing samples or evaluating the amount of color deposited onto the hair was ΔE which was calculated as described below and Yellowness Index (YI) which was calculated per ASTM Method E313.
- Method for Calculating ΔE:
- ΔE was used to indicate the efficiency of the polymeric colorant when dyeing hair. L*, a*, b* values were taken from the hair before coloring and after coloring. The changes in L*, a*, b*, ΔL*, Δa*, Δb*, were calculated and converted into ΔE values by the following equation:
-
ΔE=√{square root over (ΔL* 2 +Δa* 2 +Δb* 2)} - The higher ΔE values means greater hair color change before and after dyeing, and thus, more efficient hair colorants.
- Polymeric colorants of this invention were evaluated as semi-permanent hair colorants by coloring blonde hair swatches (bleached blonde from dark black). The blonde human hair swatches are commonly used to evaluate coloration by stylists and can be obtained from many different retailers. The hair care composition in this example was an uncolored semi-permanent hair coloring cream, Igora ColorWorx Dilutor (Schwarzkopf). For each colorant, the amount of color in the cream was adjusted so that each sample exhibited the same color strength, meaning the amount of chromophore or absorbance in each cream was the same despite the different polymer chain lengths. The maximum absorbance of the colored cream was 0.1 when measured with 1 cm path length at concentration of 1 grams/liter in methanol. The amount of cream used was 1 gram of cream per gram of hair. The cream was contacted with the hair 20 minutes before rinsing off. To evaluate the amount of color deposited onto the yak hair, the ΔE value for the colored vs. the uncolored hair was used. The results are shown in Table 3. Example compounds from Table 1 not evaluated in Table 3 are evaluated in other tests.

The shorter polymer length tends to provide higher deposition. To further study this effect on a different substrate from bleached hair, three different colorants with the same chromophore but with different polymer lengths were tested on yak belly hair. The hair care composition in this example was an uncolored semi-permanent hair coloring cream, Igora ColorWorx Dilutor (Schwarzkopf). The amount of color in the cream was adjusted so that each sample exhibited the same color strength, meaning the amount of chromophore or absorbance in each cream was the same despite the different polymer chain lengths. Similar to Application Example 1, the maximum absorbance of the colored cream was 0.1 when measured with 1 cm path length at concentration of 1 grams/liter in methanol. For this study, yak belly hair was used as the hair substrate and the hair was colored using the procedure above. The amount of cream used was 2 grams of cream per gram of hair. The cream was contacted with the hair 20 minutes before rinsing off. To evaluate the amount of color deposited onto the yak hair, the ΔE value for the colored vs. the uncolored hair was used. The results are shown in Table 4. The amount of color deposited decreases as the polymer chain length increases. As the number of EO units increase, the amount of deposition tends to decrease. The results indicate that 5 to 6 EO units is optimal.

TABLE 4 Colorant Deposition from Semi-Permanent Hair Coloring Cream onto Yak Hair Average # of ΔE Colorant EO Units Deposition Example 30 5 48.8 Example 28 10 32.4 Example 27 20 13.5 - Polymeric colorants of this invention were compared to current commercial hair dyes by coloring blonde hair (bleached blonde from dark black). A red colorant (Example 16) was put into Igora ColorWorx diluter cream at 1.5 wt % and compared to current commercial product Igora ColorWorx Red cream which contained the dyes 4-hydroxypropylamino-3-nitrophenol and 3-nitro-p-hydroxyethylaminophenol. A yellow colorant (Example 35) was similarly put into Igora ColorWorx diluter cream at 1.5 wt % and compared to current commercial product Igora ColorWorx Yellow cream which contained the dyes HC Yellow No. 13 and HC Yellow No. 2.
- Each colored cream was deposited onto hair as outlined above. The amount of cream used was 2 grams of cream per gram of hair. The cream was contacted with the hair 20 minutes before rinsing off. The L*a*b* color of the hair was then measured as outlined above. The hair was then washed using Schauma 7 Herbs Shampoo (Schwarzkopf) and dried with a hair dryer using the procedure below. The hair was fully wet using 40° C. tap water. Shampoo (0.2 grams of shampoo per 1 gram of hair) was then added to the hair and worked in using fingers for 30 seconds. The hair and shampoo were allowed to sit in a dish for another 30 seconds and then rinsed for 30 seconds using 40° C. tap water. The hair sample was then dried using a hair dryer. The hair was washed and dried twice and then its L*a*b* color was measured. The hair was then washed and dried two more times and measured again. To evaluate the amount of color deposited onto the hair and the amount of color retained on the hair after each sequence of washes, the ΔE value for the colored at any particular wash state vs. the uncolored hair was used. The retained hair color after two and four washes was evaluated by dividing the ΔE value of the washed hair by the ΔE value of the unwashed, initially deposited hair color. Higher values indicated better retention of hair color during the wash, with a value of 100% meaning no color loss.
- The polymeric colorants demonstrated superior wash performance compared to the comparative dyes (Igora Red and Igora Yellow). Red polymeric colorant exhibited substantially more color remaining than Igora Red after four washes. The absolute ΔE number of the polymeric colorant was nearly double that of the dye product, and the retained color was nearly 85% compared to only 48% for the dye. The yellow polymeric colorant exhibited an even larger improvement over the yellow dye product. The retained color for the yellow polymeric colorant was 78% compared to only 37% for the yellow dye.

However, it is believed, while not being bound to theory, that the polymeric colorants exhibited better wash performance compared to the dyes because the polymers prevent any aggregation of the colorants, which is a very common occurrence in dyes (especially in a generally oleophilic cream as is commonly used for hair coloring). Since the polymeric colorants are not aggregated and fully dispersed into the cream, it is believed they can more uniformly coat the hair fiber than the dyes which have a strong possibility of aggregation. This more uniformly coated hair fiber demonstrated less loss of color during washing compared to the dyes because the aggregated dyes are less uniformly coating the hair fiber.
- Polymeric colorants, like conventional hair dyes, can be used widely in a variety of different hair coloring formulations. This was demonstrated by taking a single polymeric colorant (Example 10) and mixing it into several different commercial uncolored semi-permanent hair coloring creams at 0.16% by mass and applied to bleached blonde hair. The amount of cream used was 1 grams of cream per gram of hair. The cream was contacted with the hair 20 minutes before rinsing off. The amount of color deposited onto the hair was evaluated by measure ΔE of the colored hair relative to the uncolored hair and is shown in Table 6.
- There were four different creams evaluated, each with different ingredients in the creams. Igora ColorWorx Dilutor (Schwarzkopf) contained Aqua, Cetearyl Alcohol, PEG-8-Coconut Alcohol, Ceteareth-20, Disodium Cocoamphodipropionate, Methylparaben, Xanthan Gum, Sulfuric Acid, Sodium Silicate, Propylparaben-Etidronic Acid, Ethanolamine. Colorista Clear Mixer (L'Oreal) contained Aqua, Cetearyl Alcohol, Behentrimonium Chloride, Amodimethicone, Cetyl Alcohol, C12-15 Alkyl Benzoate, Isopropyl Alcohol, Hydroxyethyl-Cellulose, Trideceth-6, Guar Hydroxypropyltrimonium Chloride, Chlorhexidine Digluconate, Stearyl Alcohol, Myristyl Alcohol, Citric Acid, Cetrimonium Chloride, 2-Oleamido-1,3-Octadecanediol, Fumaric Acid, Sodium Hydroxide. Color Charm Paints Clear (Wella) contained Aqua, Cetearyl Alcohol, Propylene Glycol, Steareth-20, Phenoxyethanol, Parfum/Fragrance, Potassium Phosphate, Hexyl Cinnamal, Sodium Hydroxide, Citric Acid. Color Fresh Create Tomorrow Clear (Wella) contains Aqua, Cetearyl Alcohol, Propylene Glycol, Steareth-20, Phenoxyethanol, Mica, Potassium Phosphate, Titanium Dioxide/C177891, Sodium Hydroxide, Citric Acid. The polymeric colorant is highly effective in all the evaluated creams which demonstrates these materials will work in a wide range of different formulations, each with a wide variety of ingredients.

Shampoo is a commonly used hair care composition that can also be used to deposit color onto hair. A range of polymeric colorants can be used to color hair in a shampoo formulation. The hair care composition in this example was a shampoo, BC Bonacure pH 4.5 Color Freeze Micellar Rich Shampoo (Schwarzkopf). For each colorant, the amount of colorant in the shampoo was adjusted so that each sample exhibited the same color strength, meaning the amount of chromophore or absorbance in each shampoo was the same despite the different polymer chain lengths and chromophore types. The maximum absorbance of the colored shampoo was 0.25 when measured with 1 cm path length at concentration of 1 grams/liter in methanol. For this study, bleached blonde hair was used as the hair substrate and the hair was colored using the procedure above. The amount of shampoo used was 0.2 grams of shampoo per gram of hair. The shampoo was contacted with the hair 3 minutes before rinsing off. To evaluate the amount of color deposited onto the hair, the ΔE value for the post shampoo vs. the pre-shampoo hair was used.
- In addition, the Yellowness Index (YI) was calculated for the post shampoo and the pre-shampoo hair samples and the change in YI (ΔYI) from shampoo treatment calculated. When dark hair is bleached there is preferential destruction of certain melanin pigments which leads to an undesirable warm orange/yellow or “brassy” tone to the bleached hair. A major application of the dyes in shampoo is to neutralize this warm tone to a cooler or more white tone. By evaluating the ΔYI of the hair, one can observe the desired effect of toning or neutralizing the undesired warm tone. The more the YI decreases, the less yellow or brassy the hair appears; in other words, the more negative the ΔYI of the shampoo treatment, the better the colorant covers the undesired yellow tone.
- In addition to the polymeric colorants evaluated for shampoo, a commercial dye commonly used in shampoo was also included as a comparative sample. External D&C Violet 2 (also known as Acid Violet 43) was formulated identically to the polymeric colorants in terms of absorbance per gram of shampoo. Additional mixing and time was required to fully disperse the powdered dye into the shampoo. Results are shown in Table 7. The polymeric colorants show a range of deposition performance as judged by ΔE. Unexpectedly, some of the polymeric colorants show greater deposition onto the hair in shampoo than the commonly used dye, Ext. D&C Violet 2. When the shade of the polymeric colorant is appropriate to neutralize the yellow tones of the hair (such as Example 10 and Example 11), the ΔYI is more strongly negative than comparative dye, implying that they are more effective at neutralizing yellow tones. Some colorants are not the desired shade to neutralize yellow tones in bleached hair, such as Example 30, but can be used for other colorations such as yellow, red, pink, etc.

Thus, the hair will go from yellow to desirably toned to undesirably violet or blue as the colorant continues to build. Because of the different physical properties of polymeric colorants compared to dyes, they can show better leveling behavior where they build to a certain level depending on loading and then stop building. This would allow one to safely use a shampoo daily and obtain the desired level of toning without the undesirable over-toning or violet/blue shading of hair. A polymeric colorant (Example 10) was formulated into shampoo and hair was repeatedly washed and dried over multiple cycles. A comparative example shampoo was made using Ext. D&C Violet 2 and the same experiment carried out with it.
- For this example, the shampoo was BC Bonacure pH 4.5 Color Freeze Micellar Rich Shampoo (Schwarzkopf). For each colorant/dye, the amount of colorant in the shampoo was adjusted so that each sample exhibited the same color strength; the maximum absorbance of the colored shampoo was 0.043 when measured with 1 cm path length at concentration of 1 grams/liter in methanol. This is a colorant loading level similar to many commercial toning shampoos. Bleached blonde hair was used as the hair substrate. The amount of shampoo used was 0.2 grams of shampoo per gram of hair. The shampoo was contacted with the hair 3 minutes before rinsing off. To evaluate the amount of color deposited onto the hair in each wash, the ΔE value for the hair after vs. before each shampoo wash was used. Results are shown in Table 8. As before, the polymeric colorant deposits more in the first wash than the dye. Both the dye and polymeric colorant show lower deposition in the second and third wash then the first wash. Surprisingly, the polymeric colorant shows ever decreasing deposition with increasing washes past the third wash which indicates leveling while the dye shows a steady amount of deposition past the third wash which indicates continued building of the dye onto the hair. The polymeric colorant in this case shows a desirable behavior: strong initial deposition followed by rapid leveling. This would allow a consumer to observe a clear effect after only one or two washes but safely continue using the shampoo with reduced concern of over-toning or undesirably violet or blue coloring.

Conditioner is a commonly used hair care composition that can also be used to deposit color onto hair. A range of polymeric colorants can be used to color hair in a conditioner formulation. The hair care composition in this example was a conditioner, EverPure Blonde Conditioner (L'Oreal). For each colorant, the amount of colorant in the conditioner was adjusted so that each sample exhibited the same color strength, meaning the amount of chromophore or absorbance in each conditioner was the same despite the different polymer chain lengths and chromophore types. The maximum absorbance of the colored conditioner was 0.25 when measured with 1 cm path length at concentration of 1 grams/liter in methanol.

- In addition, the Yellowness Index (YI) was calculated for the post conditioner and the pre-conditioner as described before. In addition to the polymeric colorants evaluated for conditioner, a commercial dye commonly used in conditioner was also included as a comparative sample. External D&C Violet 2 (also known as Acid Violet 43) was formulated identically to the polymeric colorants in terms of absorbance per gram of conditioner. Results are shown in Table 10. Unexpectedly, all of the evaluated polymeric colorants show greater deposition onto the hair in conditioner than the commonly used dye, Ext. D&C Violet 2. The ΔYI is also more strongly negative than the comparative dye, implying that they are more effective at neutralizing yellow tones. Also unexpectedly, several polymeric colorants show much higher deposition out of conditioner than shampoo. Example 1 shows 13 times greater ΔE in conditioner than in shampoo (see Table 7); similarly, Example 2 shows over double the ΔE in conditioner that it showed in shampoo. The polymeric colorants show very good blending into the conditioner due to their liquid nature.

Assuming the colorants are fully dissolved into the cream, one might expect that they would have poor stability in certain hair care products, especially in an oxidative hair cream containing hydrogen peroxide. Surprisingly, several examples of this type of polymeric colorant which were stable in an oxidative cream containing 12% hydrogen peroxide were discovered, as described below.
- Several polymeric colorants were tested for stability and coloring performance in a commercially available oxidative hair cream. Each sample was added to Fanola 40 Vol Perfumed Cream Developer (available from Fanola of Italy), which contained about 12% hydrogen peroxide. Each sample was mixed using a SpeedMixer at 1500 rpm until a visually uniform mixture was obtained (a minimum of 90 seconds; SpeedMixer from Inc., Landrum, S.C.). The amount of color contained in each sample was adjusted so that each sample exhibited the same color strength. The maximum absorbance of the colored cream was 0.67 when measured with 1 cm path length at concentration of 1 gram/liter in methanol. After mixing, the samples were stored first at room temperature for 7 days and then moved to a 40° C. oven. The stability of color was evaluated by the room temperature equivalent days it takes to reach 50% loss of color based the original measured color in the cream at time zero as measured by UV-VIS. Loss of color is de-coloration due to chemical changes in colorant from the oxidative cream ingredients including peroxide. Many of these colorants evaluated were stable in the oxidative emulsion as shown below in Table 13.
- The room temperature equivalent days was calculated by the following equation:
-
Room temperature equivalent days=Days stored at room temperature+Days stored at 40° C.*3.48 - Using the room temperature equivalent days for the color to degrade to 50%, a rating was generated according to the table below. A value of “1” indicated the composition was most stable, while a value of “5” indicated that it was the least stable.

TABLE 13 Stability of Inventive Polymeric Colorants in Oxidative Hair Cream Polymeric Colorant Rating Example 1 1 Example 37 1 Example 18 2 Example 10 1 - In addition to strongly coloring the hair to bright colors such as blue, red, yellow, there is also a desire to controllably deposit a less noticeable amount of certain colors to neutralize the spectrum of undertones that are exposed during the a hair bleaching or lightening process. Light brown hair, for example, would expose yellow undertones upon bleaching. Therefore, according to the law of color, a violet-based toner would neutralize the yellowish hue to result in a platinum or silver blond shade. The concentration of the toner may be adjusted so that the lift is not masked by the deposition of color. In accordance with present invention, there is a single-step process using a composition of hair bleach that can simultaneously lighten the hair and effectively deposit various shades of color. This is achieved by including dyes in the bleach composition. As demonstrated above, several of the blue and violet polymeric colorants show good stability in oxidative cream, so one can pre-mix a violet colorant into an oxidative hair cream and then simultaneously lighten hair while depositing the colorant to neutralizes the unwanted yellow tones. This is demonstrated below.
- Materials:
- Blonde Hair (lightly bleached dark hair), cut to 3 cm wide, 20 cm long
- Fanola Violet Bleach Powder
- Fanola 40 Vol. (12% peroxide) oxidative cream
- Procedure:
- The hair was weighed first in order to calculate the amount of cream needed (4 grams of cream per gram of hair). Color and oxidative cream developer were mixed as described above. The mixtures were checked and remixed when necessary to ensure the color was fully homogenous. Fanola Violet Bleach Powder (available from Fanola of Italy) was weighed into a small weigh boat (two parts cream to one part bleach powder). The appropriate amount of oxidative cream was added to the bleach powder. Using the wooden end of a cotton-tipped applicator, the bleach/cream was stirred until fully mixed. The bleach/cream mixture was transferred to a large weigh boat with the hair sample. The mixture was spread all over the hair and worked into the hair with fingertips until the mixture was fully incorporated evenly throughout the hair. The bleach was allowed to sit on the hair for 15 minutes and then the hair sample was rinsed thoroughly with lukewarm water, combed, and dried in the oven at 60° C. for 45 minutes. The color of hair was measured using the X-Rite Color-eye with a 6 mm aperture, with D-65 light source. The hair was twisted tight and pressed to the aperture while taking the measurement. An average of 6-8 measurements was used.
- As described earlier, the Yellowness Index (YI) was calculated for each sample. The YI is good indicator for how well the hair was lightened and toned. The initial hair had a whiteness index (YI) of 48.9 due to its yellow color. After treatment, the YI values decreased, indicating the hair was lightened. The differences of the YI between treated hair and initial hair, ΔYI, were recorded. Larger, more negative, ΔYI indicate better lightening of the hair.
- The YI and ΔYI values of the initial hair, bleach control (no dye), and bleach composition containing Example 1 and Comparative Example External D&C Violet 2 are shown in Table 14. The bleach composition with Example 1 provided better lightening than the bleach control and bleach with Comparative Example External D&C Violet 2.
