Composition, for the cosmetic treatment of skin, lips, nails, hair, eyelashes, eyebrows and/or scalp, comprises in a support UV filter system, dibenzoylmethane derivative, piperidine derivative, and silicon-containing s-triazine compound

摘要

Composition (A) comprises in a support at least one UV filter system, at least one dibenzoylmethane derivative, at least one piperidine derivative (I), and at least one silicon-containing s-triazine compound (II) or its tautomers. Composition (A) comprises in a support at least one UV filter system, at least one dibenzoylmethane derivative, at least one piperidine derivative of formula (I), and at least one silicon-containing s-triazine compound of formula (D-Si(R) a-O (3-a)/2) (II) or its tautomers, where (II) comprises structural units of formulae (-A-(Si)(R) a(O) (3-a)/2) and ((R) b-(Si)(O) (4-b)/2). In formula (I), R1 : 1-12C alkyl; and R2 : 1-20C alkyl. In formula (II), R : 1-30C alkyl (optionally halogenated or unsaturated), 6-12C aryl, 1-10C alkoxy, OH or trimethylsilyloxy; a : 0-3; b : 1-3; D : s-triazine group of formula (III); X : -O-or-NR3-; R3 : H or 1-5C alkyl; R1 : 1-30C alkyl (optionally unsaturated and optionally containing a silicon atom), 5-20C cycloalkyl (optionally substituted with 1-3 1-4C alkyl), -(CH 2CHR4-O) mR5 or -CH 2-CH(OH)-CH 2-O-R6; R4 : H or CH 3, where the group (C=O)XR1 can be ortho, meta or para to the amino group; R5 : H or 1-8C alkyl; R6 : H or 4-8C alkyl; m : 2-20; n1 : 0-2; either R2 : OH, 1-8C alkyl or 1-8C alkoxy; or R2R2 : 1 or 2C alkylidenedioxy; A : divalent radical comprising methylene, - [CH(Si(CH 3) 3)]-, ethylene, or groups of formula -(Z)-CH(W1)-CH 2-, -(Z)-CH(CH 3)-, -(Z)-CH=CH- or -(Z)-C(=CH 2)-; Z : optionally saturated 1-10C alkylene diradical (optionally substituted with OH or O, and optionally containing amino group); and W1 : H, OH or optionally saturated 1-8C alkyl. An independent claim is included for improving the chemical stability of at least one dibenzoylmethane derivative against UV radiation, comprising combining the dibenzoylmethane derivative with a combination of (I) and (II).
