Claim 5:
6. The process of claim 1, wherein the at least one amino silicone is chosen from amino silicones corresponding to formula (B):, wherein:
R1 is independently chosen from a hydrogen atom, a phenyl group, a hydroxyl group, a C1-C8 alkyl group;
R2 represents a monovalent radical of formula -CqH2qL wherein q is a number ranging from 2 to 8 and L is an optionally quaternized amino group chosen from:
—N(R″)2; —N+(R″)3A−; —NR″—Q—N(R″)2 and —NR″—Q—N+(R″)3A−,
wherein R″ is independently chosen from a hydrogen atom, a phenyl group, a benzyl group or a saturated monovalent hydrocarbon-based radical; Q denotes a linear or branched group of formula CrH2r, r being an integer ranging from 2 to 6; and A−represents a cosmetically acceptable anion comprising a halide;
R3 is independently chosen from a C1-C8 alkyl group, or a monovalent radical of formula —CqH2qL wherein q is a number ranging from 2 to 8 and L is an optionally quaternized amine group chosen from:
—N(R″)2; —N+(R″)3A−; —NR″—Q—N(R″)2 and —NR″—Q—N+(R″)3A−, wherein R″ is independently chosen from a hydrogen atom, a phenyl group, a benzyl group or a saturated monovalent hydrocarbon-based radical;
Q denotes a linear or branched group of formula CrH2r, r being an integer ranging from 2 to 6; and A−represents a cosmetically acceptable anion comprising a halide; and
m and n are numbers such that the sum (n+m) ranges from 1 to 2000, wherein m denotes a number from 0 to 1999, and n denotes a number from 1 to 2000.
