Composition, useful for dyeing keratin fibers, preferably human keratin fibers such as hair, comprises fatty substances, surfactants, oxidation bases, alkalizing agents and phenolic couplers
Composition comprises one or more fatty substances, surfactants, oxidation bases, alkalizing agents and phenolic couplers (I), where the amount of fatty substances is at least 25 wt.%. Composition comprises one or more fatty substances, surfactants, oxidation bases, alkalizing agents and phenolic couplers having a structure of formula (I) and their salts, optical or geometrical isomers, tautomers or hydrates, where the amount of fatty substances is at least 25 wt.%. R1-R5 : 1-8C alkyl, 3-8C alkenyl (optionally substituted), H, halo, -SR, -OR, hydrogen carbonyl, sulfonic acid, -NHCOR1a or -NHSO 2R1a, with provided that at least one of R1, R3, R5 is H, and two groups of R1R2, R3, R4, R5 is carried by adjacent carbon atoms to form, together with carbon atoms, heterocycle ring which is optionally substituted and optionally interrupted by one or more groups of at least one heteroatom comprising O, S, carbonyl or -NR2a-, where -NHCO- is a single group and/or at least one -NHSO 2- group is optionally engaged in a heterocycle； R : H, 1-8C alkyl or 3-88C alkenyl (optionally substituted)； R1a : 1-8C alkyl, 3-8C alkenyl, benzenyl (all optionally substituted) or H； and R2a : H, 1-4C alkyl or 1-4C alkylcarbonyl. Independent claims are included for: (1) dyeing keratin fibers, preferably human keratin fibers such as the hair, comprising applying the composition to the fibers in the presence of chemical oxidizing agent； and (2) a multi-compartment device comprising a first compartment containing the anhydrous composition, at least a second compartment containing the first aqueous composition and at least a third compartment containing the second aqueous composition, where the compositions of the compartments are intended to be mixed together before application to give a composition after mixing the anhydrous composition and the first and the second aqueous composition.
