Cosmetic or dermatological spherical powder or gel, useful for UV protection, contains siloxane elastomers, inorganic micropigment and certain benzotriazoles

摘要

Cosmetic and/or dermatological spherical powders or gels contain certain siloxane elastomers, inorganic micropigments and certain benzotriazoles e.g. 2-(2H-benzotriazol-2-yl)-4-methyl-6- (2-methyl-3-(1,1,3,3-tetramethyl-1-((trimethylsilyl)oxy)disiloxanyl)propyl)-phenol. Cosmetic and/or dermatological spherical powders or gels for use in UV protection comprise: (A) 2-(2H-benzotriazol-2-yl)-4-methyl-6-(2-methyl-3-(1,1,3,3-tetramethyl-1-((trimethylsilyl)oxy)disiloxanyl)propyl)-phenol (I) and/or 2,2'-methylenebis-(6-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)-phenol) (II); (B) inorganic micropigments; and (C) siloxane elastomers obtained by reaction of (i) vinyl-terminated polymethylsiloxanes and methylhydrodimethylsiloxanes or (ii) hydroxy-terminated dimethylpolysiloxanes and trimethylsiloxy-terminated methylpolysiloxanes.
