Agent, useful e.g. for oxidative coloring of keratin fibers e.g. human hair, wool and feathers, comprises substituted 4-aminophenyl compounds and/or their salt as oxidation dyestuff precursor of developer-type in a cosmetic carrier

摘要

Agent comprises at least one substituted 4-aminophenyl compound (I) and/or its salt as oxidation dyestuff precursor of developer-type in a cosmetic carrier. Agent comprises at least one substituted 4-aminophenyl compound of formula (I) and/or its salt as oxidation dyestuff precursor of developer-type in a cosmetic carrier. R1, R2 : H (preferred), 1-6C-alkyl (optionally partially or completely halogenated), 2-6C-alkenyl, 1-6C-hydroxyalkyl, 2-6C-polyhydroxyalkyl, 1-6C-alkoxy, 1-6C-alkoxy-1-4C-alkyl, halo, CN, amino-1-6C-alkyl, mono-(1-6C-alkyl)amino-1-6C-alkyl, di-(1-6C-alkyl)amino-1-6C-alkyl or optionally substituted (hetero)aryl; and Het : 10-20C-heterocycle containing at least one nitrogen atom, which is linked to the 4-aminophenyl-unit of (I). Independent claims are included for: (1) a process for coloring human hair comprising applying the coloring agent on the keratin fibers for an exposure time, preferably 5-45 minutes, and subsequently rinsing or washing the hair with a shampoo; (2) packaging units (kit-of-parts) containing at least one container-A comprising at least one preparation-A in a cosmetic carrier that contains at least one oxidation dyestuff precursor, and at least one container-B containing at least one oxidation agent preparation-B in a cosmetic carrier containing at least one oxidation agent, where the two containers are separated from one another; and (3) 4-(1,4,7,10-tetraazacyclododecan-1-yl)aniline compound.
