Composition, useful for coloring keratin fibers, preferably human hair, comprises a p-phenylene diamine compound containing a cyclic acetal group as a developer component in a carrier

摘要

Composition comprises at least one p-phenylene diamine compound, which contains at least one cyclic acetal group as a developer component in a carrier. An independent claim is included for p-phenylene diamine compound of formula (I). R1, R2 : H, 1-6C-alkoxy, halo, 1-6C-alkyl, 2-6C-alkenyl, 1-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl or (hetero)aryl; R3 : heteroaryl group of formula (a2)-(a6); n, m : 1-6; either R5, R6 : H, 1-6C-alkyl or 2-6C-alkenyl; or R5R6 : five or six membered saturated ring; either X : O or -NR7-; and R4 : H, 1-6C-alkyl, 2-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl, 1-6C-alkoxy-2-6C-alkyl, 2-6C-alkenyl, aryl-2-6C-alkyl, (hetero)aryl or heteroaryl group (a2)-(a6); or X+N+R4 : dioxazocane group of formula (a7); and R7 : H, 1-6C-alkyl, 2-6C-alkenyl, 2-6C-monohydroxyalkyl, 2-6C-polyhydroxyalkyl or 1-6C-alkoxy-2-6C-alkyl.
