USE OF SCREENING SILICONE FOR PROTECTING COLOR OF ARTIFICIALLY COLORED KERATIN FIBER IN ORDER TO RESIST AGAINST INFLUENCE OF UV IRRADIATION

摘要

PROBLEM TO BE SOLVED: To protect the color of keratin fiber artificially colored by an oxidation dye precursor, an oxidizing agent or a direct dyeing against the influence of UV irradiation by using a specific organosiloxane.;SOLUTION: An organosiloxane containing at least one ultraviolet absorbing group and selected from (A) benzotriazole silicone compounds of formula I [R is a 1-10C alkyl or the like and ≥80% R is methyl; A is a monofunctional group of formula II (Y is a 1-8C alkyl or the like; X is O or NH; (n) is 0-3; (m) is 0 or 1; (P) is 1-10; Z is H or a 1-4C alkyl) directly bonded to silicon; B is R or A; (r) is 0-50; (s) is 0-20], or the like, and (B) a benzalmalonate silicone containing at least plural units of formula III [R" is an aryl; R''' is H or the like; R'''' is a 1-5C alkyl; M is a group of formula IV (W is H or the like)] and another unit of the formula Qd-Si-O.(4-d)2 (Q is H or the like; (c) is 0-2; (d) is 0-3; (n) is 1-6) is used.;COPYRIGHT: (C)2000,JPO
