    摘要: A photostable, filtering cosmetic composition for protecting human epidermis and hair against UV rays comprises, in a cosmetically acceptable carrier having at least one fatty phase 0.5 to 4% by weight of 4-(tert.-butyl) 4'-methoxy dibenzoylmethane and 0.1 to 20% by weight of a filtering polymer of the benzotriazole silicone type containing at least one unit of formula (1), where R' is a C.sub.1 -C.sub.30 hydrocarbon group, a C.sub.1 -C.sub.8 halogenated hydrocarbon group or a trimethylsilyloxy group; a is 1 or 2; X=--A--Y where A is an aliphatic or aromatic bivalent hydrocarbon radical having at least 2 carbon atoms and optionally containing one or more oxygen atoms; Y is a 2-(2'-hydroxyphenyl)benzotriazole residue optionally containing one or more C.sub.1 -C.sub.8 alkyl, C.sub.2 -C.sub.8 alkenyl, halogen, alkoxy, carboxy, hydroxy or amino substituents, the weight ratio of the benzotriazole silicone to the 4-(tert.-butyl) 4'-methoxy dibenzoylmethane being between 1 and 10.
