Description

[Technical field]

[0001]

[0001] The present invention relates to an oxidative hair cream composition containing at least one oxidative hair cream ingredient and at least one polymeric colorant.

[0002]

[0002] Human hair is arbitrarily assigned to a scale with different levels that describe its darkness (or lightness). Black hair is designated level 1, medium brown hair level 5, and pale light blonde level 10, with some subtle differences between them. Hair bleaching is a chemical process in which melanin pigment granules are gradually destroyed by bleaching agents, resulting in a lighter hair color. Melanin pigments are not all lightened at the same rate. Eumelanin is destroyed more easily than pheomelanin. Because of this property, when dark hair is bleached, there is preferential destruction of melanin pigments, which visually accentuates the red pigments and casts an undesirable warm reddish orange or "brassy" tone in the bleached hair. To dull the warm colors, hair colorants with dulling properties are almost always applied during or after the bleaching procedure.

[0003] Based on their chemical composition and strength, hair bleaches can be classified into two groups designated as Category 1 and Category 2. Category 1 bleaches are solution or cream based compositions that utilize an alkaline hydrogen peroxide solution as the primary oxygen generator to oxidize and bleach hair melanin in conjunction with the normal hair coloring treatment. Just prior to use, the peroxide is mixed with an alkalizing agent, e.g., ammonia, and the resulting solution or cream is applied to the hair for 30-60 minutes. Such compositions can lighten hair by as much as four levels, depending on the concentration of hydrogen peroxide used. For example, level 6 hair can be lightened to level 10 under favorable conditions.

[0004] Category 2 bleaches are generally powder compositions, some in the form of creams, based on persulfates - (ammonium, potassium, sodium) as a supplementary or booster supply of active oxygen - and silicates and / or carbonates that act as a source of alkalinity. As with category 1 bleaches, these are mixed with hydrogen peroxide solution immediately prior to use to form an effective cream that can be applied to the hair. It is possible to incorporate hydrogen peroxide in solid form itself into the powder bleach, and all that is required to achieve an effective cream is the addition of water to the powder. Quite often, a separately packaged third ingredient, called a bleaching oil, is added to the bleach powder and peroxide at the time of use. The bleaching oil may contain moisturizers and other conditioning agents. Category 2 bleaches can provide more than 7 levels of lift, something that cannot be achieved with category 1 bleaches. Category 2 bleaches are typically utilized whenever more than a level 4 lift is desired, for example, lifting level 5 or darker hair to a light blonde.

[0005]

[0005] At various levels of bleaching, the underlying warm tones are exposed, so lightening hair is generally accompanied by a toning treatment to dull the warm tones and give the hair a pleasing, natural look. Toners are classified into three hues: teal, blue, and purple. These are commonly known as dull or ashy hues. These hues, or combinations of these, are recommended to dull the spectrum of undertones exposed during the lightening treatment. Light brown hair, for example, will expose yellow undertones during bleaching. Thus, by color law, a purple-based toner will dull the yellowish hues to give a platinum or silver blonde shade. The concentration of the toner should be adjusted so that the lift is not masked by color deposition. Similarly, medium brown hair will expose a significant amount of orange undertones and therefore require a significant amount of blue-based toner. Dark hair, when bleached, exhibits a reddish-orange undertone and therefore requires a bluish-green toner.

[0006]

[0006] In accordance with the present invention, there is a single-step method of using a hair bleach composition that can simultaneously lighten hair and effectively deposit a variety of color shades. This is accomplished by including a dye in the bleach composition. A dye suitable for this application must (a) be easily mixed into the oxidizing composition and remain homogenous, and (b) be stable in the bleach.

[0007] However, current small molecule dyes have weaknesses. Dyes are conjugated, rigid organic compounds that are often difficult to dissolve in compositions. Undissolved dyes can leave uneven hues, or sometimes color spots, on treated hair. Thus, liquid forms of colorants are much more desirable. In this aspect, polymeric, liquid colorants are superior to conventional hair dyes.

[0008]

[0008] Although liquid colorants are preferred for this application, it has been unexpectedly discovered that polymeric dyes often exhibit different and worse stability compared to their small molecule analogues. It was speculated that some small molecule dyes do not really dissolve in the composition and therefore separate from the oxidizing agent. However, when polymeric colorants were used, they were completely dissolved down to the molecular level and therefore exposed to the bleaching agent. Despite this general behavior, it has been further surprisingly found that polymeric dyes containing azo chromophores are stable in the bleaching agent and provide superior performance in this application.

[0032]

[0033] Also suitable are various kinds of alkoxylated sorbitan and alkoxylated sorbitan derivatives. For example, alkoxylation, especially ethoxylation, of sorbitan leads to polyalkoxylated sorbitan derivatives.

[0035] The hair cream composition may optionally contain one or more anionic surfactants. The preferred range of anionic surfactant is about 0.01-25%, preferably 0.5-20%, more preferably 1-15% by weight of the total oxidizing composition. Suitable anionic surfactants include those of the formula ROSO3M and RO(C2H4O) x Included are alkyl sulfates and alkyl ether sulfates, generally having the formula SO3M, where R is an alkyl or alkenyl of about 10 to 20 carbon atoms, x is 1 to about 10, and M is a water soluble cation, such as ammonium, sodium, potassium, or triethanolamine cation.

[0034]

[0036] Another class of anionic surfactants that can be used in the compositions of the present invention are the water-soluble salts of organic, sulfuric acid reaction products of the general formula: R1-SO3-M, where R1 is selected from the group consisting of straight or branched chain, saturated, aliphatic hydrocarbon radicals having from about 8 to about 24 carbon atoms, preferably from 12 to about 18 carbon atoms, and M is a cation. Examples of such anionic surfactants are the salts of organic sulfuric acid reaction products of hydrocarbons, such as n-paraffins having from 8 to 24 carbon atoms, and sulfonating agents, such as sulfur trioxide.

[0035]

[0037] Also suitable as anionic surfactants are the reaction products of fatty acids esterified with isethionic acid and neutralized with sodium hydroxide, or fatty acid reactants with alkanolamines or ammonium hydroxide. The fatty acid may be derived, for example, from coconut oil. Examples of fatty acids also include lauric acid, stearic acid, oleic acid, palmitic acid, etc.

[0036]

[0038] In addition, succinates and succinimates are suitable anionic surfactants.

The alpha-olefins from which the olefin sulfonates are obtained are mono-olefins having about 12 to 24 carbon atoms, preferably about 14 to 16 carbon atoms.

[0038]

[0040] Another class of suitable anionic organic surfactants are the β-alkoxyalkanesulfonates or water-soluble soaps thereof, e.g., C 10~20 Salts of fatty acids, such as coconut and tallow based soaps. Preferred salts are ammonium, potassium, and sodium salts.

In particular, the chelating agents chelate metal ions found in water and prevent these ions from interfering with the deposition and reaction of the dye on the hair fiber surface. Suitable chelating agents include EDTA and its calcium, sodium, or potassium derivatives, HEDTA, sodium citrate, TEA-EDTA, and the like.

[0046]

[0108]

[0108] Alkalizing agent

[0109] The oxidative hair cream composition may have an alkaline pH. Exemplary pHs include 7, 8, 9, 10, 11, 12, 13, or 14. In some embodiments, the pH of the composition may range from about 7, 8, or 9 to about 9, 10, 11, or 12. The alkalinity of the oxidative hair cream composition may be derived from one or more alkalizing agents. In some embodiments, the alkalizing agent may be ammonia or ammonia gas-producing compounds and / or amines or ammonium-based compounds in an amount sufficient to render such compositions alkaline. In further embodiments, the alkalizing agent may be selected from alkanolamines, such as monoethanolamine (MEA) and isopropanolamine. The alkalinity may be derived from ammonium compounds (e.g., NH4OH). The one or more alkalizing agents may be present in an amount ranging from about 0, or 1, 2, 3, 4, 5, 10 to greater than about 5, 10, 13, 15, 18, 20, 25, or 30% by weight of the total composition.

[0109]

[0110] The oxidative hair cream composition may be in the form of a cream, an aqueous solution, a homogeneous dispersion or suspension of surfactants, or even a liquid. Such compositions are acceptably phase stable and typically have a viscosity ranging from about 1 to 1,000,000 cps, more preferably about 10 to 100,000, most preferably 100 to 20,000 cps, and even more preferably 1000 to 10000 cps. For purposes of the present invention, viscosity is measured on a Brookfield LVDV-II+ viscometer apparatus at room temperature, 1 rpm, and with the corresponding cup and spindle.

[0110]

[0111] The oxidative hair cream composition of the present invention also contains at least one polymeric colorant. The polymeric colorant may be an azopolymeric colorant. The term "polymeric colorant" generally refers to a colorant having at least one chromophore moiety attached to at least one oligomeric or polymeric chain, the chain having at least two repeat units. The oligomeric or polymeric constituent may be attached to the chromophore by any suitable means, such as covalent bonds, ionic bonds, or suitable electrostatic interactions. In general, the polymeric colorant may be characterized as 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 present invention, the polymeric colorant (which may be an azopolymeric colorant in one aspect) may have a maximum absorbance in the range of 400 nanometers to 700 nanometers, or a maximum absorbance in the range of 470 nanometers to 700 nanometers, or even in the range of 550 nanometers to 700 nanometers.

[0111]

[0112] As a function of the method of manufacture, polymeric colorants have a molecular weight that is typically expressed as a molecular weight distribution. Thus, the molecular weight of a polymeric colorant is commonly reported as an average molecular weight determined by its molecular weight distribution.

[0112]

[0113] The chromophore moiety of the polymeric colorant can vary widely and can include compounds that are characterized in the art as dyes or pigments. The actual group used will depend to a large extent on, for example, the desired color, color fastness, and stability characteristics. The chromophore moiety may be attached to at least one polyalkyleneoxy substituent through a suitable linking moiety, such as nitrogen, oxygen, sulfur, etc.

[0113]

[0114] In one aspect, the chromophore group may be a neutral or uncharged molecule. In a further aspect, the chromophore group may be nonionic, anionic, or cationic. The polymeric colorant may contain chromophores that have both positive and negative charges. Additionally, the polymeric colorant may contain chromophores that are zwitterionic or amphoteric.

[0114]

[0115] Examples of chromophore groups include nitroso, nitro, azo (including monoazo, diazo, bis-azo, disazo, trisazo, tetrakisazo, polyazo, formazan, azomethine and metal complexes thereof), stilbene, bis-stilbene, biphenyl, oligophenethylene, fluorene, coumarin, naphthalamine, diarylmethane, triarylmethane, xanthenacridine, quinoline, methine (including polymethine), thiazole, indamine, indophenol, azine, thiazine, oxazine, aminoketone, hydroxyketone, anthraquinone (including anthrapyrazoline, anthron, anthrapyridone, anthrapyridine, flavanthrone, pyranthrone, benzanthrone, perylene, perinone, naphthalimide and other structures formally related to anthraquinone), indigoid (including thioindigoid), phthalocyanine chromophore groups, and mixtures thereof. In one aspect of the invention, the polymeric colorant is an azopolymeric colorant.

[0115]

[0116] An example of a suitable polymer chain is a polyalkyleneoxy chain. The term "polyalkyleneoxy," as used herein, generally refers to a molecular structure containing the following repeat units: -CH2CHO-, CH2CH2CHO-, -CH2CH2CH2CHO-, -CH2CH(CH3)O-, -CH2CH(CH2CH3)O-CH2CH2CH(CH3)O-, CH2CH(O-)(CHO-), and any combination thereof.

[0116]

[0117] Typical of such groups that may be attached to the chromophore group are polyalkylene oxides and copolymers thereof. Typical polyalkylene oxides and copolymers thereof that may be utilized to obtain colorants include those made from alkylene oxide monomers containing 2 to 20 carbon atoms, or more preferably, 2 to 6 carbon atoms. Examples include polyethylene oxide; polypropylene oxide; polybutylene oxide; oxetane; tetrahydrofuran; copolymers of polyethylene oxide, polypropylene oxide, and polybutylene oxide; and other copolymers, including block copolymers in which the majority of the polymeric substituents are polyethylene oxide, polypropylene oxide, and / or polybutylene oxide. Additionally, such polyalkyleneoxy groups may have an average molecular weight ranging from about 132 to about 10,000, preferably from about 176 to about 5000.

[0117]

[0118] It should be understood that since the colorant may or may not be chemically bound to ingredients including the oxidative hair cream composition, the exact chemical identity of the end group of the polyalkyleneoxy group may not be critical as long as the proper function of the colorant in the composition is considered. With this in mind, certain most preferred colorants are defined in which certain end groups are identified. The recitation of such end groups is in no way to be construed as limiting the invention in its broader aspects. According to such most preferred aspects, the colorant can be characterized as follows:

[0119] R{A[(alkyleneoxy constituents) n R1] m} x wherein R is an organic chromophore group, A is a linking moiety of said organic chromophore group selected from the group consisting of N, O, SO2 or CO2, the alkylene portion of the alkyleneoxy constituent contains 2 to about 4 carbon atoms, n is an integer from 2 to about 230, when A is O, SO2 or CO2, m is 1, when A is N, m is 1 or 2, x is an integer from 1 to 5, the product of n times x times m (nmx) is 2 to about 230, and R1 is

[0118] [ka]

[0119]

[0120] and each member of said groups is a member of the group consisting of sulfonates and sulfates, R2 is H, an alkyl radical containing up to about 20 carbon atoms or a carboxy terminated alkyl radical containing up to about 20 carbon atoms, j and k are OH, OM or OR3, M is the cationic moiety of an alkali metal, alkaline earth metal, transition metal, such as nickel, or ammonium, R3 is an alkyl radical containing up to about 20 carbon atoms, and R4 is the alkylene portion of the alkyleneoxy repeat unit.

[0120]

[0121] The oligomeric constituents include, but are not limited to, (i) C2-C 20 (ii) an oligomer comprising at least two monomers or repeating units selected from the group consisting of alkyleneoxy groups, glycidol groups, and glycidyl groups; and (ii) an oligomer comprising the structure (I):

[0121] [ka]

[0122] In structure (I), R2 and R3 can be any suitable moiety, including oligomeric moieties selected from the group consisting of aromatic or aliphatic oligomeric esters conforming to the formula: 10alkyl groups, f is an integer between 1 and 10, inclusive, and g is any positive integer or fraction between 1 and 20, inclusive. As will be appreciated by those skilled in the art, suitable values ​​for g include both integers and fractions, since the length of the oligomeric constituents on individual polymeric colorant molecules can vary. Thus, the value for g represents the average length of the ester chains for a given sample or collection of polymeric colorant molecules. In certain embodiments, the polymeric colorant can include one or more oligomeric constituents that are composed of two or more ethylene oxide monomer groups.

[0123]

[0122] The polymeric colorant may be alkoxylated. In one aspect of the present invention, the polymeric colorant is an alkoxylated azopolymeric colorant. Alkoxylation is carried out by procedures well known to those skilled in the art (see, for example, USPN 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).

[0124] Exemplary polymeric colorants include Liquitint® polymeric colorants, Cleartint® polymeric liquid concentrated colorants, Reactint® polymeric colorants, and Palmer® polymeric colorants, all of which are available from Milliken Chemical, a division of Milliken & Company of Spartanburg, SC. ​​Liquitint® polymeric colorants are characterized as water-soluble, non-staining colorants. Polymeric colorants are widely used in laundry detergents, fabric softeners, and other consumer and industrial cleaning products. Liquitint® polymeric colorants are generally bright liquid colorants, but depending on the specific colorant, they exhibit different degrees of water solubility. These colorants are generally compatible with other chemicals present in their end-use formulations and can also typically be characterized as easy to handle. Liquitint® polymeric colorants can be used to impart color to both water-based and solid systems. Liquitint® polymeric colorants, due to their unique polymeric nature, provide a more subtle staining effect on skin, fabrics, hard surfaces, equipment and more.

[0125] Cleartint® polymer liquid concentrated colorants are liquid colorants specifically designed for frequent use in coloring transparent polypropylene articles. These colorants can be easily incorporated into polypropylene resins to provide transparent, clear, brightly colored polypropylene articles without adversely affecting the article's transparency. Cleartint® liquid concentrated polymer colorants are oligomeric coloring materials that combine the exceptional visual aesthetics of dyes with the migration resistance of pigments. These colorants can be used as light tints to mask residual haze, or they can be used to obtain deep, rich shades not possible with pigment colorants. Cleartint® liquid concentrated polymer colorants enable transparent polypropylene to rival the aesthetics of higher-cost plastic materials. The technical and physical property benefits of transparent polypropylene can be utilized without sacrificing the visual aesthetics of the product.

[0126] Reactint® polymeric colorants are liquid polymeric colorants useful for pigmenting polyurethanes and other thermosets. These colorants are reactive polymeric colorants consisting of chromophores chemically bonded to a polyol. 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% homogenous liquids that are soluble in polyols and will not settle over time. This pure liquid and easily dispersible nature allows Reactint® colorants to be blended in-line and on the fly while producing polyurethane foams and resins.

[0127] Palmer® polymeric colors are liquid colors developed specifically for use in washable applications, such as markers, paints, and other technical product washable applications. These colors contain no heavy metals, are non-toxic, and have excellent non-staining properties on skin, fabrics, and other surfaces. Palmer® polymeric colors are very compatible with water-based ink formulations and provide bright colors.

[0143]

[0132] Other colorants that can be combined with the polymeric colorants to form the colorant portion of the oxidative hair cream composition are also contemplated within the scope of the present invention. For example, colorants 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, etc. Thus, the colorant of the oxidative hair cream composition may be composed of a blend or mixture of polymeric and non-polymeric colorants. The polymeric and non-polymeric colorants may have the same chromophore groups or they may have different chromophore groups.

[0144]

[0133] The oxidative hair cream composition of the present invention is prepared by combining at least one oxidizing agent with at least one polymeric colorant, the oxidative hair cream composition thus formed can be a substantially homogenous mixture.

[0145] The process for preparing the oxidative hair cream composition of the present invention comprises the following steps: (a) providing at least one oxidizing agent; (b) providing at least one polymeric colorant; and (c) combining at least one oxidizing agent with at least one polymeric colorant to form a polymeric colorant-containing oxidative hair cream.

[0146] The method for applying color to hair according to the present invention comprises the following steps: (a) preparing an oxidative hair cream containing a polymeric colorant; (b) applying an oxidative hair cream containing a polymeric colorant to the hair; (c) contacting the hair cream with the hair for a period of time; and (d) Removing the hair cream from the hair.

[0147] The method for bleaching and applying color to hair according to the present invention comprises the following steps: (a) preparing an oxidative hair cream containing a polymeric colorant; (b) applying an oxidative hair cream containing a polymeric colorant to the hair; (c) contacting the hair cream with the hair for a period of time; and (d) Removing the hair cream from the hair.

[0148] The oxidative hair cream composition may be contacted with the hair for a period ranging from 10 seconds to 1 hour, or from 30 seconds to 45 minutes, or from 1 minute to 30 minutes, or from 3 minutes to 15 minutes. The hair may be moistened with water before application of the hair cream or the hair may be dry at the time the hair cream is applied to the hair.

[0149]

[0138] Oxidative hair creams can be permanent (e.g., 80% of the original color intensity is still visible after 20 wash cycles), semi-permanent (e.g., 80% of the original color intensity is visible until 20 wash cycles, but is not visible thereafter), or temporary (e.g., 80% of the original color intensity is visible until 5 wash cycles, but is not visible thereafter). The permanence of the hair color on the hair can depend on the particular polymer colorant contained in the hair cream and / or the amount of polymer colorant contained in the hair cream. For example, increasing the amount of polymer colorant in the hair cream can make the color last longer on the hair. In contrast, a lower amount of polymer colorant contained in the hair cream can make the color last shorter on the hair. Also, the amount of time that the oxidative hair cream remains in contact with the hair during the coloring process can affect the amount of color, the depth of color and / or shade, and the permanence of the hair color on the hair. For example, leaving the hair cream on the hair for a longer period during the hair coloring treatment may result in a deeper shade and / or color and the color lasting longer on the hair.

[0150]

[0139] In one aspect of the invention, the amount of polymeric colorant in the hair cream is in the range of 0.0001% to 10%, or in the range of 0.1% to 5%.

[0151]

[0140] In one aspect of the present invention, the molecular weight of the polymer colorant in the hair cream is in the range of 100 to 10,000, or in the range of 200 to 5,000, or in the range of 300 to 2,000.

[0152]

[0141] At least one polymeric colorant described herein can be added to an oxidative hair cream composition for use in coloring hair. As a result, the present invention also includes hair (or keratin-containing materials) containing at least one polymeric colorant. The present invention further includes a method for bleaching and / or coloring hair (or keratin-containing materials), comprising the steps of preparing the hair, applying and / or depositing an oxidative hair cream composition described herein onto the hair, contacting the oxidative hair cream composition with the hair for a period of time, and further agitating, rinsing, and / or drying the hair thus treated.

[0153]

[0142] In these types of oxidizing systems there are typically two components. One component contains an oxidizing species (e.g., hydrogen peroxide). The second component contains other species, typically those designed to raise the pH, but also other oxidizing species, e.g., persulfates. In one aspect of the invention, the two components are mixed together before application to the hair. The first application contains 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.

[0154]

[0143] Thus, in one embodiment, at least one polymeric colorant is mixed into a cream containing an oxidizing agent. Just prior to use, the polymeric colorant / hydrogen peroxide containing cream is mixed with at least one other ingredient to raise the pH by an amount sufficient to activate the hydrogen peroxide. In an alternative embodiment, the polymeric colorant may be added to a second component. In this case, the second component is added to a non-colored hydrogen peroxide cream just prior to use.

[0155]

[0144] Although the invention described herein is primarily directed to oxidative hair creams containing polymeric colorants, the invention is not limited to these compositions. The oxidative hair cream may contain a combination of a polymeric colorant and another colorant. The other colorants include, for example, dyes, pigments, and combinations thereof.

[0156] Suitable dyes include small molecule dyes selected from the group consisting of dyes that fall within the Color Index (CI) classification 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 having the 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, Acid Violet 50, Acid Blue 15, Acid Blue 17, Acid Blue 25, Acid Blue 29, Acid Blue 40, Acid Blue 45, Acid Blue 75, Acid Blue and small molecule dyes selected from the group consisting of: Acid Blue 80, Acid Blue 83, Acid Blue 90 and Acid Blue 113, Acid Black 1, Basic Violet 1, Basic Violet 3, Basic Violet 4, Basic Violet 10, Basic Violet 35, Basic Blue 3, Basic Blue 16, Basic Blue 22, Basic Blue 47, Basic Blue 66, Basic Blue 75, Basic Blue 159, Colour Index (Society of Dyers and Colourists, Bradford, UK) numbers Acid Violet 17, Acid Violet 43, Acid Red 52, Acid Red 73, Acid Red 88, Acid Red 150, Acid Blue 25, Acid Blue 29, Acid Blue 45, Acid Blue 113, Acid Black 1, Direct Blue 1, Direct Blue 71.

[0157]

[0146] Suitable dyes include dyes selected from the group consisting of flavanthrone, indanthrone, chlorinated indanthrone containing 1 to 4 chlorine atoms, pyranthrone, dichloropyranthrone, monobromodichloropyranthrone, dibromodichloropyranthrone, tetrabromopyranthrone, perylene-3,4,9,10-tetracarboxylic acid diimide (the imide group may be unsubstituted or substituted with C1-C3-alkyl or phenyl or heterocyclic radicals, the phenyl and heterocyclic radicals may carry further substituents which do not impart solubility in water), anthrapyrimidine carboxylic acid amide, violanthrone, isoviolanthrone, dioxazine dyes, copper phthalocyanines which may contain up to 2 chlorine atoms per molecule, polychloro-copper phthalocyanines or polybromochloro-copper phthalocyanines containing up to 14 bromine atoms per molecule and mixtures thereof.

[0158] In one aspect of the invention, the components of the oxidative hair care composition can be prepared by combining the components in any convenient order and mixing, e.g., stirring, the resulting combination of components to form a phase-stable semi-liquid (i.e., cream) composition. In another method for preparing such a composition, a liquid matrix is ​​formed containing at least a major proportion of the liquid components, preferably substantially all of the liquid components, and the liquid combination is subjected to shear agitation to thoroughly mix the liquid components. For example, rapid agitation using a mechanical stirrer can be effectively utilized. While the shear agitation is maintained, substantially all of the raw ingredients in solid form can be added. Agitation of the mixture is continued and, if necessary, agitation of the mixture can be intensified at this point to form a solution or uniform dispersion of the insoluble solid phase particles in the liquid phase. As a variation of the composition preparation procedure described thus far, one or more of the solid components can be added to the agitated mixture, which is a solution or slurry of particles premixed with a minor portion of one or more of the liquid components. After all of the composition components have been added, stirring of the mixture is continued for a time sufficient to form a composition having the desired viscosity and phase stability characteristics, which often involves stirring for about 30 to 60 minutes.

[0159]

[0148] The oxidative hair creams of the present invention can be combined with other molecules, compounds, and / or agents useful for applying the oxidative hair cream to hair and / or enhancing color performance. The other molecules, compounds, and / or agents include, for example, surfactants, solvents, preservatives, antimicrobial agents, antibacterial agents, fragrances, and the like, and combinations thereof.

[0160] The oxidative hair cream compositions of the present invention may also include any number of additional optional ingredients. These include conventional hair colorant composition ingredients, such as alkalizing agents (e.g., ammonia), alkalinity sources (e.g., silicates and / or carbonates), moisturizers, conditioning agents, thickeners, non-coloring dyes, detergent builders, enzymes, enzyme stabilizers, suds suppressors, pH adjusters, chelating agents, smectite clays, solvents, hydrotropes and phase stabilizers, structurants, opacifiers, perfumes, and colorants. The various optional oxidative hair cream composition ingredients, when present in the compositions herein, should be utilized in concentrations conventionally utilized to provide their desired contribution to the composition or hair bleaching and / or coloring method. In many cases, the total amount of such optional oxidative hair cream composition ingredients can range from about 0.01% to about 50% by weight of the composition, more preferably from about 0.1% to about 30% by weight.

[0161]

[0150] [ example ] Several polymeric and monomeric colorants were tested for stability and color performance in a commercial oxidative hair cream. Each sample was added to Fanola 40 Vol Perfumed Cream Developer (available from Fanola of Italy), which contained approximately 12% hydrogen peroxide. A SpeedMixer was used at 1500 rpm to mix each sample for a minimum of 90 seconds until a visually homogenous mixture was obtained. (SpeedMixer, Inc., Landrum, SC). The amount of color contained in each sample was adjusted so that each sample exhibited the same color intensity. The maximum absorbance of the colored cream was 0.67, measured at a concentration of 10 grams / liter in methanol, at a 1 cm path length. After mixing, the samples were first stored at room temperature for 7 days and then transferred to a 40° C. oven. Color stability was evaluated by the equivalent number of days at room temperature required to reach 50% color loss, based on the original color measured in the cream at time zero, as measured by UV-VIS. The color loss is due to chemical changes from the oxidative cream ingredients, including peroxide.

[0162]

[0152] The equivalent number of days at room temperature was calculated using the following equation: Equivalent number of days at room temperature = Days stored at room temperature + Days stored at 40°C * 3.48 The number of days equivalent to 50% degradation at room temperature was used to rate according to Table 1. A rating of "1" means most stable, while a rating of "5" is least stable.

[0163]

[0153]

[0164] [Table 1]

[0165]

[0154] The inventive colorants and stability test results are shown in Table 2A. Comparative colorants and stability test results are shown in Table 2B.

[0166]

[0155]

[0167] [Table 2]

[0168]

[0156]

[0169] [Table 3]

[0170]

[0157] The test results show that not all polymeric triarylmethane dyes were stable (Comparative Examples 1-5). Other polymeric dye classes, such as cyanines (Comparative Example 6), methines (Comparative Example 7), and anthraquinones (Comparative Examples 8 and 9), were also not stable. Monomeric anthraquinone dyes, such as External D&C Violet 2 (Comparative Example 10) and Solvent Violet 13 (Comparative Example 11), were found to have better stability compared to their polymeric counterparts (Comparative Examples 8 and 9), although they were difficult to blend into creams.

[0171]

[0158] Coloring performance evaluation

[0159] Material: Blonde hair (lightly bleached dark hair) was cut into pieces 3 cm wide and 20 cm long. Fanola Violet Bleach Powder Fanola 40Vol. (12% peroxide) Oxidizing cream

[0160] Procedure: The hair was first weighed to calculate the amount of cream needed (4 grams of cream per gram of hair). The color and oxidative cream developer were mixed as described above. The mixture was checked and remixed if necessary to ensure the color was completely homogenous. Fanola Violet Bleach Powder (available from Fanola of Italy) was weighed into a small weighing dish (2 parts cream and 1 part bleach powder). The appropriate amount of oxidative cream was added to the bleach powder. The wooden end of a cotton swab was used to stir the bleach / cream until completely mixed. The bleach / cream mixture was transferred to a large weighing dish with the hair sample. The mixture was spread throughout the hair and rubbed into the hair with fingertips until the mixture was completely incorporated evenly throughout the hair. The bleach was allowed to sit on the hair for 15 minutes, then the hair sample was rinsed thoroughly with warm water, combed, and dried in an oven at 60°C for 45 minutes. Hair color was measured using an X-Rite Color-eye with a 6mm aperture and D-65 light source. The hair was tightly twisted and forced into the aperture while taking the measurement. An average of 6-8 measurements were used.

[0172]

[0162] CIE WI is a good measure of how well the hair was lightened. The initial hair had a whiteness index (WI) of -76.6 due to its yellow color. After treatment, the WI value increased, indicating that the hair was lightened. The difference in WI between the treated hair and the initial hair, ΔWI, was recorded. A larger ΔWI indicates a better lightening of the hair.

[0173]

[0163] The WI and ΔWI values ​​for the initial hair, the bleach control (no dye), and the bleach compositions containing Example 1 and Comparative Example 10 (External D&C Violet 2) are shown in Table 3. The bleach composition using Example 1 provided better lightening than the bleach control and the bleach using Comparative Example 10.

[0174]

[0164]

[0175] [Table 4]

[0176] When dark hair is bleached, the melanin pigment is destroyed, which visually accentuates the red pigment and casts an undesirable warm reddish orange or "brassy" tone on the bleached hair. This brassy tone is typically corrected by post-bleach application of a violet or blue dye. The blue or violet is complementary to the orange and yellow brassy tones, effectively dulling them. The dye can be delivered in a shampoo, conditioner, mask, hair cream, or similar. It is preferred to add a violet or blue colorant to the bleaching cream so that the brassy tones are dulled directly during the bleaching process, thus eliminating the need for additional color treatment. The challenge is that the oxidizing cream is generally aggressive, and many colorants fade. The present invention relates to a specific subset of dyes that are stable in oxidative creams upon storage and also provide color correction to dull brass tones.

[0177] Unexpectedly, the polymeric colorants deposit more strongly than the comparative dyes. It is customary to expect dyes to have better deposition than polymeric colorants because the colorants have a higher molecular weight and the polymer should improve the water solubility of the colorants, which may reduce deposition. However, without being bound by theory, it is believed that dyes tend to exhibit stronger aggregation in the more lipophilic creams, while polymeric colorants essentially disperse completely into the cream due to a better energy match to the cream medium and steric hindrance of the polymer chains, which limits the ability of the colorants to self-associate. Thus, these dye aggregates are effectively much larger in size than the polymeric colorants, even though the molecular weight of the individual dyes is small. Smaller sized, fully dispersed polymeric colorants can deposit very uniformly along the length of the hair fiber, while the dye aggregates are limited in uniformity and overall extent of deposition due to their larger relative size. Thus, the larger molecular weight polymeric colorants deposit much more strongly on the hair than the dyes, completely unexpectedly.
