Description

Technical Field

[0001] This invention relates to compositions for keratin fibers, particularly compositions for bleaching or dyeing keratin fibers such as hair. Background Technology

[0002] It is known to use dyeing compositions containing oxidative coloring precursors (commonly referred to as oxidative color-developing bases) such as o- or p-phenylenediamines, o- or p-aminophenols, and heterocyclic compounds to dye keratin fibers, particularly hair. These oxidative color-developing bases are typically combined with color-forming agents (couplers). Both these oxidative color-developing bases and color-forming agents are colorless or weakly colored compounds. However, when combined with oxidants, they can provide colored dye molecules through an oxidative condensation process.

[0003] This type of coloring, achieved through oxidation, known as oxidative dyeing, makes it possible to obtain colors with very high visibility, coverage of white hair, and a wide variety of shades. Oxidative dyeing is widely used due to its superior color payoff compared to direct dyeing using so-called direct dyes.

[0004] To perform oxidative staining, a composition containing one or more oxidizing bases and one or more chromogenic agents and one or more alkaline agents is typically mixed with a developer composition containing one or more oxidizing agents to prepare a ready-to-use composition, which is then applied to keratin fibers.

[0005] The color-developing composition is capable of bleaching keratin fibers due to the action of one or more oxidizing agents in the composition. Therefore, the color-developing composition and the ready-to-use composition (which may or may not contain any oxidizing chromogenic base, and may or may not contain any color-forming agent) can be used to bleach keratin fibers. Summary of the Invention

[0006] Preferably, the above-mentioned composition can provide good bleaching or dyeing effects.

[0007] On the other hand, bleaching or dyeing keratin fibers with the above-mentioned compositions tends to damage the keratin fibers because they contain one or more alkaline agents.

[0448] Analogous products are specifically described in EP 173109 and more particularly in Example 3 therein. More precisely, this polymer is a dimethyl m-isopropenyl benzyl isocyanate terpolymer of methacrylic acid / methyl acrylate / ethoxylated benzyl alcohol (40EO) as a 25% aqueous dispersion. This product is supplied by AMERCHOL under the name VISCOPHOBE DB1000.

[0449] Also suitable are cationic associative polyurethane thickeners, a family described by the applicant in French patent application No. 0009609. They can be more specifically represented by the following general formula (A): RX-(P) n -[L-(Y) m ] r -L′-(P′) p-X′-R′(A), wherein: R and R′, which may be the same or different, represent a hydrophobic group or a hydrogen atom; X and X′, which may be the same or different, represent a group containing an amine functional group with or without a hydrophobic group, or a group L″; L, L′, and L″, which may be the same or different, represent a group derived from a diisocyanate; P and P′, which may be the same or different, represent a group containing an amine functional group with or without a hydrophobic group; Y represents a hydrophilic group; r is an integer between 1 and 100, preferably between 1 and 50, and particularly between 1 and 25; n, m, and p are each independent of the others between 0 and 1000; the molecule contains at least one protonated or quaternized amine functional group and at least one hydrophobic group.

[0450] In a highly advantageous embodiment, the only hydrophobic groups in these polyurethanes are the terminal groups R and R′.

[0451] According to the first preferred embodiment, the associative polyurethane thickener corresponds to formula (Λ), where R and R′ each independently represent hydrophobic groups, X and X′ each represent group L″, n and p are between 1 and 1000, and L, L′, L″, P, P′, Y and m have the meanings indicated in formula (A).

[0453] The fact that n and p equal 0 means that these polymers do not contain units derived from monomers containing amine functional groups that are incorporated into the polymer during polycondensation. The protonated amine functional groups of these polyurethanes are generated by the hydrolysis of excess isocyanate functional groups at the chain ends, followed by alkylation of primary amine functional groups by alkylating agents containing hydrophobic groups, i.e., compounds of the type RQ or R′Q, where R and R′ are as defined above and Q represents a leaving group such as a halide, sulfate, etc.

[0454] According to another preferred embodiment of the invention, the associative polyurethane thickener corresponds to formula (A), wherein R and R′ each independently represent a hydrophobic group, X and X′ each independently represent a group containing a quaternary amine, n and p are equal to zero, and L, L′, Y and m have the meanings indicated in formula (A).

[0455] The number average molecular weight of cationic associative polyurethane thickeners is typically between 400 and 500,000 g / mol, particularly between 1,000 and 400,000 g / mol, and ideally between 1,000 and 300,000 g / mol.

[0456] When X and / or X′ represent a group containing a tertiary or quaternary amine, X and / or X′ may represent one of the following:

[0468] The groups P and P′ containing amine functional groups can represent at least one of the following:

[0469]

[0474] A - It is a physiologically acceptable counterion.

[0475] Regarding the meaning of Y, the term "hydrophilic group" is understood to refer to a polymeric or non-polymeric water-soluble group. For example, when not referring to a polymer, ethylene glycol, diethylene glycol, and propylene glycol may be mentioned. According to a preferred embodiment, in the case of a hydrophilic polymer, for example, polyethers, sulfonated polyesters, sulfonated polyamides, or mixtures of these polymers may be mentioned. Preferably, the hydrophilic compound is a polyether, and particularly polyethylene oxide or polypropylene oxide.

[0476] The cationic associative polyurethane thickener of formula (A) is formed from a diisocyanate and various compounds having functional groups containing unstable hydrogen. The functional groups containing unstable hydrogen can be alcohol, primary or secondary amine, or thiol functional groups, which, upon reaction with the diisocyanate functional groups, respectively produce polyurethane, polyurea, and polythiourea. The term "polyurethane" in this invention encompasses these three types of polymers: polyurethane itself, polyurea, and polythiourea, and their copolymers.

[0477] The first type of compound used in the preparation of polyurethane according to formula (A) is a compound containing at least one unit with an amine functional group.

A mixture of polyfunctional and difunctional compounds may also be used, wherein the percentage of the polyfunctional compound is low.

[0478] As shown above, such compounds may contain more than one unit containing an amine functional group. Therefore, they are repeating polymers containing units containing amine functional groups.

[0482] For example, methylene diphenyl diisocyanate, methylene cyclohexane diisocyanate, isophorone diisocyanate, toluene diisocyanate, naphthalene diisocyanate, butane diisocyanate and hexane diisocyanate may be mentioned.

[0483] The third compound in the preparation of polyurethane of formula (Λ) is a hydrophobic compound intended to form the terminal hydrophobic group of the polymer of formula (Λ).

[0484] This compound consists of a hydrophobic group and a functional group containing unstable hydrogen, such as a hydroxyl, primary or secondary amine, or thiol functional group.

[0485] For example, such compounds can be fatty alcohols, such as stearyl alcohol, dodecyl alcohol, and decanol in particular. When such compounds contain polymer chains, they can be, for example, hydroxylated hydrogenated polybutadiene.

[0486] The hydrophobic groups of the polyurethane of formula (A) can also be generated by the quaternization reaction of a tertiary amine of a compound containing at least one tertiary amine unit. Therefore, the hydrophobic groups are introduced via a quaternizing agent. This quaternizing agent is a compound of type RQ or R′Q, where R and R′ are as defined above and Q represents a leaving group such as a halogen, sulfate, etc.

[0487] Cationic associative polyurethane thickeners may additionally contain hydrophilic sequences. These sequences are provided by a fourth type of compound incorporated into the polymer preparation. This compound may be multifunctional, preferably difunctional. It may also be a mixture containing a low percentage of multifunctional compounds.

[0488] The functional group containing unstable hydrogen is an alcohol, primary or secondary amine, or thiol functional group. Such a compound can be a polymer with one of these functional groups containing unstable hydrogen at the chain end.

[0489] For example, when polymers are not involved, ethylene glycol, diethylene glycol, and propylene glycol can be mentioned.

[0490] 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, and particularly polyethylene oxide or polypropylene oxide.

[0491] The hydrophilic group labeled Y in formula (A) is optional. In fact, units containing quaternary or protonated amine functional groups are sufficient to provide the required solubility or water dispersibility of this type of polymer in aqueous solutions. While the presence of the hydrophilic group Y is optional, cationic associative polyurethane thickeners containing such groups are preferred.

[0492] The associative polyurethane thickeners used in this invention may also be nonionic, particularly nonionic polyurethane-polyethers. The nonionic polyurethane-polyethers may have both at least one hydrophilic portion and at least one hydrophobic portion. More specifically, the polymers may contain both hydrophilic sequences (most commonly polyoxyethylene types) and hydrophobic sequences (which may be individual aliphatic bonds and / or alicyclic and / or aromatic bonds) in their chains.

[0493] Preferably, these polyether-polyurethanes comprise at least two lipophilic hydrocarbon chains having 6 to 30 carbon atoms, preferably 6 to 20 carbon atoms, separated by a hydrophilic sequence. These hydrocarbon chains may be side chains or chains at the ends of the hydrophilic sequence. In particular, one or more side chains are contemplated. Furthermore, the polymer may contain hydrocarbon chains at one or both ends of the hydrophilic sequence.

[0494] Polyether-polyurethanes can be multiblock, particularly triblock, in form. Hydrophobic sequences can be present at each end of the chain (e.g., in triblock copolymers with hydrophilic central sequences) or both at the ends and in the chain (e.g., in multiblock copolymers). These same polymers can also be in the form of grafted units or can be star-shaped.

[0495] Associative polyurethane thickeners can form a network in water, in which, for example... Figure 1 The hydrophobic portion shown is connected to the quasi-micelles.

[0496] Therefore, associative polyurethane thickeners can increase the viscosity or consistency of the compositions according to the invention. Consequently, after application of the compositions according to the invention, the compositions can quickly recover their original elasticity.

[0497] Nonionic polyether-polyurethane containing aliphatic chains can be triblock copolymers, whose hydrophilic sequence is a polyoxyethylene chain containing 50 to 1000 oxyethylene groups.

[0498] The nonionic polyether-polyurethane contains urethane bonds between hydrophilic sequences, hence its name.

[0499] Furthermore, those whose hydrophilic sequences are linked to hydrophobic sequences via other chemical bonds are also included in nonionic polyether-polyurethanes containing hydrophobic chains.

[0500] For example, nonionic polyether-polyurethane containing hydrophobic chains that can be used in this invention can also be used, specifically those containing urea functional groups sold by RHEOX. 205 or 208, 204, or 212, and Acrysol RM

[0501] It can also be mentioned that AKZO contains C 12 -C 14ELFACOS, a product with alkyl chains and containing C 18 ELFACOS, a product with alkyl chains

[0502] Alternatively, you can use C from ROHM & HAAS. 20 DW, a product with an alkyl chain and urethane bonds It is sold with a dry matter content of 20% in water.

[0506] Preferably, the polyurethane-polyether comprises at least two hydrocarbon-based lipophilic chains having 8 to 30 carbon atoms separated by hydrophilic blocks, wherein the hydrocarbon-based chains are selected from side chains and chains at the ends of the hydrophilic blocks.
