dibenzoylmethanderivate and nanopigment from titanium dioxide containing composition and its uses

摘要

A cosmetic compsn. for topical application, esp. for photo-protection of the skin and/or hair, comprises, in a cosmetically acceptable vehicle, (i) at least one dibenzoylmethane deriv. (I), and (ii) at least one TiO2 pigment that is coated and/or treated with a silicone, with the proviso that the compsn. is free from benzylidene camphor cpds. of formula (II), where D, E = H, 1-20C opt. branched alkyl, or a gp. -OR; and R = H or 1-20C opt. branched alkyl. Pref. the TiO2 pigment may be coated prior to the silicone treatment with a coating agent other than a silicone, esp. alumina, silica, cpds. of Al, cpds. of Si or mixts. of these. The mean size of the elementary particles of the pigment is pref. 5-100 nm, and esp. 50 nm.
