Abstract:
1. A cosmetic composition comprising at least one nonionic polysiloxane/polyurea block copolymer, at least one colored or coloring entity, and at least one volatile nonsilicone organic solvent; wherein the at least one polysiloxane/polyurea copolymer is chosen from compounds of formula (I): wherein: R is chosen from monovalent hydrocarbon radicals comprising from 1 to 20 carbon atoms which can be substituted by at least one atom chosen from fluorine and chlorine atoms, X is chosen from alkylene radicals comprising from 1 to 20 carbon atoms, in which nonneighboring methylene units can be replaced by —O— radicals, A is chosen from oxygen and amino radicals —NR′—, Z is chosen from oxygen and amino radicals —NR′—, R′ is chosen from hydrogen and alkyl radicals comprising from 1 to 10 carbon atoms, Y is chosen from divalent hydrocarbon radicals, optionally substituted by at least one atom chosen from fluorine and chlorine, comprising from 1 to 20 carbon atoms, D is chosen from alkylene radicals, optionally substituted by at least one radical chosen from fluorine, chlorine, C n is a number ranging from 1 to 4000, a is a number greater than or equal to 1, b is a number ranging from 0 to 40, c is a number ranging from 0 to 30, and d is a number greater than 0, with the proviso that A, in at least one of the units (a), is an —NH— radical; and further comprising at least one silicone compound having a viscosity of less than 100 mm wherein the cosmetic composition is a hair dye.
