Abstract
Photoprotective/cosmetic compositions well suited for enhanced photoprotection of human skin and/or hair, as well as of a wide variety of other photosensitive materials and substrates, e.g., inorganic or organic glasses, plastics or the like, against the deleterious effects of UV-A and UV-B irradiation, particularly solar radiation, comprise a photoprotecting effective amount of a novel insoluble benzalmalonate/phenylcyanoacrylate-substituted s-triazine compound having the structural formula (I): ##STR1## in which R.sub.1, R.sub.1 ' and R.sub.1 ", which may be identical or different, are each a monovalent radical having one of the formulae (A) or (B) below:
Claims10
An insoluble benzalmalonate/phenylcyanoacrylate-substituted s-triazine compound having the structural formula (I):
- ##STR5## in which R.sub.1, R.sub.1 ' and R.sub.1 ", which may be identical or different, are each a monovalent radical having one of the formulae (A) or (B) below:
- ##STR6## wherein R.sub.2 and R.sub.2 ', which may be identical or different, are each a linear or branched C.sub.1 -C.sub.3 alkyl radical;
- R.sub.3 is a hydrogen atom, a linear or branched C.sub.1 -C.sub.4 alkyl radical or a C.sub.1 -C.sub.4 alkoxy radical;
- R.sub.4 is a linear or branched C.sub.1 -C.sub.12 alkyl radical;
- and X.sub.1 is a hydrogen atom or a phenyl radical optionally substituted with a halogen atom or with a C.sub.1 -C.sub.4 alkyl radical or C.sub.1 -C.sub.4 alkoxy radical.
