Description

Technical Field

[0001] The present invention relates to a composition for keratin fibers, in particular a composition for decolorizing or dyeing keratin fibers such as hair.

Background Art

[0002] It is known to dye keratin fibers, especially hair, using a dyeing composition containing oxidation bases generally called oxidation precursors, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and heterocyclic compounds. These oxidation bases are generally combined with a coupler. These oxidation bases and couplers are colorless or weakly colored compounds. However, when combined with an oxidizing agent, they can provide colored dye molecules through an oxidative condensation process.

[0003] This type of coloring by oxidation, i.e., oxidative dyeing, enables the obtaining of colors with very high visibility, coverage of white hair and a variety of color tones. Oxidative dyeing is widely used because it has a higher color uptake compared to direct dyeing using so-called direct dyes.

[0004] To carry out oxidative dyeing, typically a composition containing an oxidation base and a coupler is mixed with an alkaline agent and a developer composition containing an oxidizing agent to prepare a ready-to-use composition, and then the ready-to-use composition is applied onto the keratin fibers.

[0005] The developer composition can decolorize keratin fibers due to the function of the oxidizing agent in the composition. Therefore, the developer composition and the ready-to-use composition (which may not contain any oxidation base with or without any coupler) can be used to decolorize keratin fibers.

[0006] It is preferred that the compositions described above can provide a good decolorizing or dyeing effect.

[0007] On the other hand, since the keratin fibers are decolorized or dyed with the above-described composition, they tend to be damaged because they contain an alkaline agent.

[0008] Therefore, there is a need for a composition that can decolorize or dye keratin fibers such as hair, which can reduce damage to the keratin fibers and at the same time provide a good decolorization or dyeing effect.

[0290] The associative thickener may be an associative polymer thickener, preferably an associative polyurethane thickener.

[0291] The associative polyurethane thickener may be cationic or nonionic.

[0292] Among the associative polyurethane thickeners, those that can be mentioned are associative polyurethane derivatives, for example, about 20% to 70% by mass of a carboxylic acid containing α,β-monoethylenic unsaturation, about 20 to 80% by mass of a non-surfactant monomer containing α,β-monoethylenic unsaturation, and about 0.5 to 60% by mass of a nonionic mono-urethane obtained by polymerization of the reaction product of a mono-hydroxylated surfactant with a monoethylenic unsaturated monoisocyanate.

[0293] The same is described in particular in EP 173109, more specifically in Example 3 thereof. More precisely, this polymer is a terpolymer of methacrylic acid / methyl acrylate / ethoxylated behenyl alcohol (40 EO) dimethylmethaisopropenylbenzyl isocyanate as an aqueous dispersion at 25%. This product is provided by AMERCHOL under the reference name VISCOPHOBE DB1000.

[0294] Also preferred is a cationic associative polyurethane thickener, the family of which has been described by the applicant in French Patent Application No. 0009609. More specifically, these are represented by the general formula (A): R-X-(P) n -[L-(Y) m r -L'-(P') p -X'-R'(A) (wherein R and R' are the same or different and represent a hydrophobic group or a hydrogen atom, X and X' are the same or different and represent a group containing an amine functional group which may or may not hold a hydrophobic group, or represent an L'' group, L, L', and L'' are the same or different and represent a group derived from a diisocyanate, P and P' are the same or different and represent a group containing an amine functional group which may or may not hold a hydrophobic group, Y represents a hydrophilic group, r is an integer between 1 and 100, preferably between 1 and 50, particularly between 1 and 25, n, m, and p are each independently between 0 and 1000, and the molecule contains at least one protonated or quaternized amine functional group and at least one hydrophobic group).

[0295] In a very advantageous embodiment, the only hydrophobic groups of these polyurethanes are the R and R' groups at both ends of the chain.

[0296] According to a first preferred embodiment, the associative polyurethane thickener corresponds to the formula (A) [wherein both R and R' independently represent a hydrophobic group, X and X' each represent an L'' group, n and p are between 1 and 1000, and L, L', L'', P, P', Y, and m have the meanings shown in formula (A)].

[0298] ​The fact that n and p are equal to 0 means that these polymers do not contain units derived from monomers containing amine functional groups incorporated into the polymer during polycondensation. The protonated amine functional groups of these polyurethanes are derived from the hydrolysis of excess isocyanate functional groups at the chain ends, followed by alkylation of primary amine functional groups formed by a compound of the alkylating agent containing a hydrophobic group, i.e., of the RQ or R'Q type [wherein R and R' are as defined above and Q represents a leaving group such as a halide, sulfate, etc.].

[0299] According to another preferred embodiment of the present invention, the associative polyurethane thickener corresponds to formula (A) [wherein both R and R' independently represent a hydrophobic group, both X and X' independently represent a group containing a quaternary amine, n and p are equal to zero, and L, L', Y and m have the meanings shown in formula (A)].

Preferably, the hydrophilic compound is a polyether, particularly polyethylene oxide or polypropylene oxide.

[0312] The cationic associative polyurethane thickener of formula (A) is formed from diisocyanates and various compounds having a functional group containing labile hydrogen. The functional group containing labile hydrogen may be an alcohol functional group, a primary or secondary amine functional group, or a thiol functional group that imparts polyurethane, polyurea and polythiourea respectively after reaction with the diisocyanate functional group. The term "polyurethane" in the present invention targets these three types of polymers, namely polyurethane, polyurea and polythiourea in the strict sense, and their copolymers.

[0313] The first type of compound that serves as a material for preparing the polyurethane of formula (A) is a compound containing at least one unit containing an amine functional group. This compound may be polyfunctional, but preferably, the compound is difunctional, that is, according to a preferred embodiment, this compound contains, for example, two labile hydrogen atoms held by hydroxyl, primary amine, secondary amine or thiol functional groups. It is also possible to use a mixture of polyfunctional compounds and difunctional compounds, where the percentage of polyfunctional compounds is low.

[0319] The third compound that serves as a material for preparing the polyurethane of formula (A) is a hydrophobic compound intended to form a terminal hydrophobic group of the polymer of formula (A).

[0320] This compound consists of a hydrophobic group and a functional group containing labile hydrogen, such as a hydroxyl, primary or secondary amine, or thiol functional group.

[0321] As an example, this compound may be a fatty alcohol, such as, in particular, stearyl alcohol, dodecyl alcohol, and decyl alcohol. When this compound contains a polymerizable chain, it may be, for example, hydroxyl hydrogenated polybutadiene.

[0322] The hydrophobic group of the polyurethane of formula (A) may be due to the result of the quaternization of the tertiary amine of a compound containing at least one tertiary amine unit. Therefore, the hydrophobic group is introduced by a quaternizing agent. This quaternizing agent is a compound of the RQ or R'Q type (wherein R and R' are as defined above, and Q represents a leaving group such as a halide, sulfate, etc.).

[0323] The cationic associative polyurethane thickener may additionally contain a hydrophilic sequence. This sequence is provided by a fourth type of compound that serves as a material for preparing the polymer. This compound may be polyfunctional. It is preferably bifunctional. It is also possible to have a mixture with a low percentage of polyfunctional compounds.

[0324] The functional group containing labile hydrogen is each functional group of an alcohol, primary or secondary amine, or thiol. This compound may be a polymer terminated at the chain end by one of these functional groups containing labile hydrogen.

[0325] As an example, when the polymer is not involved, ethylene glycol, diethylene glycol, and propylene glycol can be mentioned.

[0326] In the case of hydrophilic polymers, examples include polyethers, sulfonated polyesters, sulfonated polyamides, or mixtures of these polymers. Preferably, the hydrophilic compound is a polyether, particularly polyethylene oxide or polypropylene oxide.

[0327] The hydrophilic group designated as Y in formula (A) is optional. In practice, units containing quaternary or protonated amine functional groups can sufficiently provide the solubility or water dispersibility required for this type of polymer in aqueous solution. The presence of the hydrophilic group Y is optional, but cationic associative polyurethane thickeners containing such groups are nevertheless preferred.

[0328] The associative polyurethane thickener used in the present invention may also be nonionic, particularly a nonionic polyurethane-polyether. The nonionic polyurethane-polyether may have both at least one hydrophilic moiety and at least one hydrophobic moiety. More specifically, the polymers may contain, in their chains, most often both polyoxyethylene-based hydrophilic sequences and hydrophobic sequences that can be aliphatic linkages alone and / or alicyclic and / or aromatic linkages.

[0329] Preferably, these polyether-polyurethanes contain at least two lipophilic hydrocarbon chains having 6 to 30, preferably 6 to 20 carbon atoms, separated by hydrophilic sequences, and these hydrocarbon chains can be pendant chains or chains at the ends of the hydrophilic sequences. In particular, it is possible to envision one or more pendant chains. In addition, the polymer can contain hydrocarbon chains at one or both ends of the hydrophilic sequence.

[0330] The polyether-polyurethane may be in the form of a polyblock, in particular a triblock. The hydrophobic sequences may be at each end of the chain (for example, a triblock copolymer having a hydrophilic central sequence), or may be distributed at both ends and in the chain (for example, a polyblock copolymer). These same polymers may also be in the form of graft units or may be star-shaped.

[0331] Associative polyurethane thickeners can form a network in water in which the hydrophobic part connects pseudo micelles.

[0332] Therefore, associative polyurethane thickeners can increase the viscosity or consistency of the compositions according to the invention. Thus, after application of the compositions according to the invention, it can rapidly recover the original elasticity of the composition.

[0333] Nonionic polyether-polyurethanes containing fatty chains may be triblock copolymers in which their hydrophilic sequences are polyoxyethylenated chains containing 50 to 1000 oxyethylenated groups.

[0334] Nonionic polyether-polyurethanes contain urethane bonds between the hydrophilic sequences, which is the origin of the name.

[0335] By extension, those in which their hydrophilic sequences are linked to the hydrophobic sequences by other chemical bonds are also included among the nonionic polyether-polyurethanes containing hydrophobic chains.

[0336] Examples of nonionic polyether-polyurethanes containing hydrophobic chains that can be used in the present invention include Rheolate® 205 containing urea functional groups, sold by RHEOX, or alternatively Rheolate® 208, 204 or 212, and Acrysol RM 184® can also be used.

[0337] Also mentionable are products ELFACOS T210 (registered trademark) and ELFACOS T212 (registered trademark) manufactured by AKZO, which contain an alkyl chain, and C 12 ~C 14 products ELFACOS T210 (registered trademark) and ELFACOS T212 (registered trademark) manufactured by AKZO, which contain an alkyl chain, and C 18 products ELFACOS T210 (registered trademark) and ELFACOS T212 (registered trademark) manufactured by AKZO, which contain an alkyl chain, and C

[0338] C 20 Product DW 1206B (registered trademark) manufactured by ROHM & HAAS, which contains an alkyl chain, has a urethane bond and is sold with a 20% dry matter content in water, can also be used.

[0339] It is also possible to use solutions or dispersions of these polymers, especially in water or aqueous-alcoholic media. Examples of such polymers that can be mentioned are Rheolate (registered trademark) 255, Rheolate (registered trademark) 278 and Rheolate (registered trademark) 244 sold by RHEOX. It is also possible to use products DW 1206F and DW 1206J provided by ROHM & HAAS.

Whistler, 2nd Edition, published by Academic Press Inc., and the contents of these three publications are incorporated in their entirety for reference.

[0371] For example, starch, guar gum, cellulose, and their derivatives can be used.

[0372] Among the starches that can be used are, for example, polymers in the form of a polymer containing base units that are anhydroglucose units. The number of these units and their assembly make it possible to distinguish amylose (linear polymer) from amylopectin (branched polymer). The relative proportions of amylose and amylopectin, as well as their degree of polymerization, can vary depending on the plant origin of the starch.

[0373] The starch molecules used may have grains or tubers as their plant origin. Therefore, starch can be selected, for example, from the starches of corn, rice, cassava, tapioca, barley, potato, wheat, sorghum, and pea.

[0380] Among the hydroxyalkyl groups that can be mentioned are, for example, the groups hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl.

[0381] These guar gums are well-known in the prior art and can be prepared, for example, by reacting a corresponding alkene oxide such as propylene oxide with guar gum to obtain a guar gum modified with a hydroxypropyl group.

[0382] The degree of hydroxyalkylation corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxy functional groups present in the guar gum and may be, for example, in the range of 0.4 to 1.2.

[0383] Such non-ionic guar gums optionally modified with hydroxyalkyl groups are, for example, sold by Rhodia Chimie (Meyhall) under the trade names Jaguar HP8, Jaguar HP60, Jaguar HP120, Jaguar DC 293 and Jaguar HP 105, or by Aqualon under the name Galactasol 4H 4FD2 and are on the market.

All numerical values regarding the amounts of the components shown in Table 1 are based on "mass%" of the raw materials.

[0432] [Table 1]

[0433] [Evaluation] (Decolorization Test) Each of the compositions according to Example 1 and Comparative Examples 1 to 3 was mixed with a developer at the blending ratio shown in Table 2. The mixing mass ratio of the composition and the developer was 1 to 1.

[0434] [Table 2]

[0435] 3 g of the thus obtained mixture was applied to 1 g of a strand of natural black hair of a Chinese person at 27°C for 35 minutes, and then the strand was washed with water, shampooed, rinsed once, and dried.

[0436] Before and after the above decolorization method, the color difference of the hair strand was evaluated using a Minolta CM-3600A. ΔΕ* was calculated based on CIE1976 by the following formula (1): ΔΕ* i = {(L i -L0) 2 + (a i -a0) 2 + (b i -b0) 2} 1 / 2 (1) was calculated by.

[0437] In formula (1), (L i , a i , b i ) refers to the (L*, a*, b*) values of the hair strand after decolorization, and (L0, a0, b0) refers to the (L*, a*, b*) values of the hair strand before decolorization.

[0438] The ΔE* value was scored according to the following evaluation criteria. The larger the ΔE*, the greater the decolorization. A: >20 B: 19 - 20 C: 18 - 19 D: <18

[0439] The results are shown in Table 1.

[0453] Each of the compositions according to Examples 2 - 4 and Comparative Example 4 was mixed with a developer having the formulation ratio shown in Table 2 above. The mixing mass ratio of the composition to the developer was 1 to 1.

[0454] 3 g of the mixture thus obtained was applied to 1 g of strands of natural black hair of Chinese people at 27 °C for 35 minutes. Subsequently, the strands were washed with water, shampooed, rinsed once, and dried.

[0455] The color difference of the hair strands before and after the above dyeing method was evaluated using a Minolta CM-3600A. ΔΕ* was calculated based on CIE1976 by the following formula (1): ΔΕ* i = {(L i -L0) 2 + (a i -a0) 2 +(b i -b0) 2} 1 / 2 (1) and calculated by the following formula.

[0456] In formula (1), (L i , a i , b i ) represent the (L*, a*, b*) values of the hair strands after bleaching, and (L0, a0, b0) represent the (L*, a*, b*) values of the hair strands before bleaching.

[0457] The results are shown in Table 3. The greater the ΔΕ*, the greater the bleaching.

[0458] It was found that the use of the fatty substance contributed to a higher bleaching effect than the non-use of the fatty substance. Furthermore, the use of 40% by mass or more, preferably 50% by mass or more, of the fatty substance provided a significantly higher bleaching effect than the non-use of the fatty substance.
