Abstract:
A topically applicable sunscreen/cosmetic composition suited for the photoprotection of human skin and/or hair, comprising synergistically effective amounts of each of (a) at least one benzotriazole compound having the structural formula (I): ##STR36##in which A is a hydrogen atom or a divalent radical --L--W--; n has the value 1, 2 or 3; the radicals Y, which may be identical or different, are each a C.sub.1 -C.sub.10 alkyl radical, a halogen atom, a C.sub.1 -C.sub.10 alkoxy radical, or a sulfo group, with the proviso that, in the latter case, two adjacent Y radicals on the same aromatic nucleus may together form an alkylidenedioxy radical in which the alkylidene moiety was 1 or 2 carbon atoms, also with the proviso that the Y radicals are other than a sulfo group when A is other than a hydrogen atom; L is a divalent radical of the following formula (II): ##STR37##in which X is O or NH; Z is a hydrogen atom or a C.sub.1 -C.sub.4 alkyl radical; n is an integer ranging from 0 to 3, inclusive; m is 0 or 1; p is an integer ranging from 1 to 10 inclusive; W is a radical of the following formula (1), (2) or (3): ##STR38##in which formulae the radicals R, which may be identical or different, are each a C.sub.1 -C.sub.10 alkyl radical, phenyl or 3,3,3-trifluoro-propyl radical, at least 80% by number of the R radicals being methyl radicals; the radicals B, which may be identical or different, are each an R radical or the V radical of the following formula: ##STR39##in which Y, n and L are as defined above; r is an integer ranging from 0 to 50, inclusive, and s is an integer ranging from 1 to 20, inclusive, and, if s=0, at least one of the two B radicals is a radical V; u is an integer ranging from 1 to 6, inclusive, and t is an integer ranging from 0 to 10, inclusive, with the proviso that t+u is equal to or greater than 3; (b) at least one bisresorcinyltriazine compound; and (c) at least one compound containing at least two benzoazolyl functional groups per molecule or at least one compound containing, per molecule, at least one benzodiazolyl functional group, formulated into a topically applicable, cosmetically acceptable vehicle, diluent or carrier therefor.
