光過敏性１，３，５−トリアジン誘導体、ジベンゾイルメタン誘導体、及び２つのアミノベンゾエート又はアミノベンズアミド基で置換されたケイ素含有Ｓ−トリアジンを含有する光保護組成物

摘要

Cosmetic composition comprises a filtering system in a support comprising UV filter of dibenzoylmethane derivative, a UV filter of 1,3,5-triazine i.e. photosensitive in the presence of a dibenzoylmethane derivative and a silicated s-triazine compound (I) or its tautomer forms, substituted by two aminobenzoate or aminobenzamide compound. Cosmetic composition comprises a filtering system in a support comprising UV filter of dibenzoylmethane derivative, a UV filter of 1,3,5-triazine i.e. photosensitive in the presence of a dibenzoylmethane derivative and a silicated s-triazine compound of formula (D)-Si((R) a)-O ( 3 - a ) / 2 (I) or its tautomer forms, substituted by two aminobenzoate or aminobenzamide compound. R : 1-30C alkyl (optionally halogenated or unsaturated), 6-12C aryl, 1-10C alkoxy or trimethylsilyloxy, preferably -CH 3; a : 0-3, preferably 1-2; D : s-triazine compound of formula (II); X : -O- (preferred) or -NR 3-; R 3H or 1-5C alkyl; R 11-20C alkyl (optionally unsaturated and optionally containing Si) or 5-20C cycloalkyl (optionally substituted by 1-3 substituents of 1-4C alkyl, (CH 2CHR 4-O) mR 5 or -CH 2-CH(OH)-CH 2-O-R 6), preferably 4-5C alkyl, where the group (C=O)XR 1 may be in ortho, meta or para position to the amino groups, preferably in para position; R 4H or CH 3; R 5H or 1-8C alkyl; R 6H or 4-8C alkyl; m : 2-20; n : 0-2, preferably 0; either R 2OH, 1-8C alkyl or 1-8C alkoxy; or R 2R 21-2C alkylidene dioxy; A : methylene, -CH(Si(CH3) 3)-, ethylene, alkylene moiety of formula -Z-CH(W 1)-CH 2- or alkene moiety of formula -Z-CH=CH- or -Z-C=CH 2-; Z : 1-10C diradical alkylene (optionally substituted by OH or O and optionally containing amino group), preferably -CH 2-; and W 1H (preferred), OH or 1-8C alkyl. An independent claim is included for the process for improving the stability of a 1,3,5-triazine derivative i.e. photosensitive in the presence of a dibenzoylmethane derivative, in UV radiation comprising addition of the silicated s-triazine compound (I) to the composition.
