Abstract
The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dye(s), b) one or more titanium salts and b1) optionally at least one carboxylic acid, and c) one or more anionic thickening polymers derived from the polymerization of at least one monomer bearing an organic monoacid function, and d) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.
Claims20
A method for dyeing keratin fibers, comprising applying to the fibers:
- a) at least one dye chosen from oxidation dyes and direct dyes, of synthetic or natural origin;
- b) at least one organic titanium salt, wherein the organic titanium salt is chosen from those compounds according to formula (I-A) below:
- wherein:
- A is chosen from a monovalent group when n is 0 or a polyvalent group when n is greater than or equal to 1;
- or a saturated or unsaturated, cyclic or non-cyclic and aromatic or non-aromatic hydrocarbon-based group comprising from 1 to 50 carbon atoms which is optionally interrupted with at least one heteroatom and/or optionally substituted;
- n, n′, and n″ may be identical or different, n is an integer ranging from 0 to 4, n′ and n″ are integers chosen from 1, 2, 3, or 4, wherein n′+n″=6;
- M1 and M2, which may be identical or different, represent a cationic counterion;
- and
- TiYn″ is chosen from Ti(OH)n″, Ti(O)n″/2, or Ti(OH)m1(O)m2with m1+m2=n″;
- b1) at least one carboxylic acid according to formula (I) below:
- wherein:
- A is chosen from a monovalent (C1-C6)alkyl groups or polyvalent (C1-C6)alkylene groups optionally substituted with at least one hydroxyl group;
- and
- n is an integer ranging from 0 to 5;
- and
- c) at least one anionic thickening polymer derived from the polymerization of at least one monomer bearing an organic monoacid function.
A cosmetic composition for dyeing keratin fibers, comprising:
- a) at least one dye chosen from oxidation dyes and direct dyes, of synthetic or natural origin;

- wherein:
- A is chosen from a monovalent group when n is 0 or a polyvalent group when n is greater than or equal to 1;
- or a saturated or unsaturated, cyclic or non-cyclic and aromatic or non-aromatic hydrocarbon-based group comprising from 1 to 50 carbon atoms which is optionally interrupted with at least one heteroatom and/or optionally substituted;
- n, n′, and n″ may be identical or different, n is an integer ranging from 0 to 4, n′ and n″ are integers chosen from 1, 2, 3, or 4, wherein n′+n″=6;
- M1 and M2, which may be identical or different, represent a cationic counterion;
- and
- TiYn″ is chosen from Ti(OH)n″, Ti(O)n″2, or Ti(OH)m1(O)m2 with m1+m2=n″;
- c) at least one carboxylic acid according to formula (I) below:
- wherein:
- A is chosen from monovalent (C1-C6)alkyl groups or polyvalent (C1-C6)alkylene groups optionally substituted with at least one hydroxyl group;
- and
- n is an integer ranging from 0 to 5;
- and
- d) at least one anionic thickening polymer derived from the polymerization of at least one monomer bearing an organic monoacid function.
