Patent ID: 8092552

Claim:
A composition for coloring keratin fibers, comprising, in a cosmetically acceptable medium, at least one oxidation dye, aqueous ammonia, ammonium chloride in an amount greater than 1.5% by weight relative to the total weight of the composition, and at least one additive selected from ceramides, silicas, crosslinked homopolymers of acrylic acid, copolymers of dialkyldiallylammonium chloride and acrylic acid, and cationic polymers composed of repeat units of formula A below: in which: (i) R′ 1 , R′ 2 , R′ 3 and R′ 4 , which are identical or different, are chosen from aliphatic, alicyclic, and aryl aliphatic groups containing 1 to 6 carbon atoms, and aliphatic hydroxyl (C 1 -C 6 ) alkyl groups; or (ii) R′ 1 , R′ 2 , R′ 3 and R′ 4 , together or separately, constitute, with the nitrogen atoms to which they are attached, saturated heterocycles having five or six members, optionally comprising a second heteroatom other than nitrogen; or (iii) R′ 1 , R′ 2 , R′ 3 and R′ 4 are chosen from linear and branched C 1 -C 6 alkyl groups substituted by a nitrile, ester, acyl, amide; —CO—O—R′ 5 -D groups; and —CO—NH—R′ 5 -D groups, in which R′ 5 is a C 1 -C 6 alkylene group and D is a quaternary ammonium group containing C 1 -C 6 alkyl groups which are identical or different; A 1 and B 1 are chosen from polymethylene groups containing 2 to 6 carbon atoms, which may be linear or branched, saturated or unsaturated, and may contain bonded to (substitutent) or intercalated in the main chain, a C 6 aromatic ring, or an oxygen or sulphur atom, or sulphoxide, sulphone, disulphide, amino, alkylamino, hydroxyl, quaternary ammonium, ureido or ester groups or combinations thereof; and X − is an anion derived from an organic or inorganic acid; and in which: A 1 , R′ 1 and R′ 3 may form, with the two nitrogen atoms to which they are attached, a piperazine ring.
