摘要

Composition comprises (i) fatty substances, (ii) surfactants, (iii) oxidation bases, (iv) alkalizing agents, (v) benzimidazole-derived couplers (I) and their salts, optical and geometrical isomers, tautomers and/or solvates, and (vi) chemical oxidizing agents. The amount of fatty substances is 10 wt.%. Composition comprises (i) fatty substances, (ii) surfactants, (iii) oxidation bases, (iv) alkalizing agents, (v) benzimidazole-derived couplers of formula (I) and their salts, optical and geometrical isomers, tautomers and/or solvates, and (vi) chemical oxidizing agents. The amount of fatty substances is 10 wt.%. R1 : H or linear or branched 1-6C alkyl (substituted by OH, preferably 2-hydroxyethyl); and R2-R5 : linear or branched 1-6C alkyl, linear or branched 1-6C, preferably 1C alkoxy (both optionally substituted by OH, preferably 2-hydroxyethyl), H or halo, preferably chloro. Independent claims are included for: (1) dyeing keratin fibers, preferably human keratin fibers such as hair, comprising applying the composition on the keratin fibers; and (2) a device comprising compartments comprising a first compartment containing the composition (A) and a second compartment containing the composition (B), where the compositions are intended to be mixed before the application.
