Patent ID: 7905927

Claim:
A method for coloring and/or lightening human keratin fibers, comprising applying to the fibers at least one first composition comprising at least one fat, at least one nonionic surfactant, and at least one compound of formula (I): in which: R 1 , R 2 , and R 3 , which are identical or different, denote: a linear or branched C 1 -C 20 alkoxy radical in which the alkyl moiety is optionally interrupted by at least one oxygen atom, a linear or branched C 2 -C 20 alkenyloxy radical, R 4 is a divalent radical of structure: in which: R 6 , identical or different at each occurrence, denotes a linear or branched C 1 -C 4 alkyl radical, which is optionally substituted by at least one entity chosen from hydroxyl groups, NH 2 radicals, hydroxyl radicals, cyano radicals, Z 12 NH 2 radicals, Z 13 NH Z 14 NH 2 radicals, and linear or branched C 2 -C 10 , alkenyl radicals, with Z 12 , Z 13 and Z 14 denoting, independently of one another, a C 1 -C 20 , linear alkylene radical R 8 denotes a linear or branched C 1 -C 4 alkyl radical, which is optionally substituted by at least one group chosen from hydroxyl and carboxyl groups, linear or branched C 2 -C 10 alkenyl radicals, Z 15 NH 2 radicals, Z 16 R 8 ′ radicals and Z 17 Si OSi(R a ) 2 (R b ) radicals where R a denotes a linear or branched C 1 -C 4 alkoxy radical R b denotes a linear or branched C 1 -C 4 alkyl radical Z 15 , Z 16 and Z 17 denote, independently of one another, a C 1 -C 20 linear alkylene radical R 8 ′ denotes a C 6 -C 30 aryl radical R 9 denotes a linear or branched C 1 -C 4 alkyl radical Z 5 , Z 6 , Z 7 , Z 8 , Z 9 , Z 10 and Z 11 denote, independently of one another, a C 1 -C 20 linear alkylene radical Q denotes a ring containing six members which is saturated or unsaturated and optionally comprises at least one heteroatom Y, identical or different at each occurrence, represents an oxygen atom, a sulphur atom or an NH group h is 0, 1, 2, 3, 4 or 5 i is 0 or 1 j is 0, 1, 2 or 3 k is 0 or 1 m is 0 or 1 n is 0 or 1 p is 0 or 1 q is 0 or 1 r is 0, 1, 2 or 3 s is 0 or 1 t is 1 or 2 at least one of the coefficients h, i, j, k, m, n, p, q, r and s is non-zero a represents the bond to the silicon atom, and b represents the bond to the nitrogen atom of the amino group; and applying to the fibers at least one second, aqueous composition comprising at least one oxidizing agent.
