Claim:
A topically applicable cosmetic/sunscreen composition comprising at least one UV-screening system which comprises: (a) at least one dibenzoylmethane compound and a photostabilizing amount of (b) at least one dithiolane compound of formula (I) below: in which: Y is O or NR 1 ; R 1 is a hydrogen atom, a saturated linear C 1 -C 20 or branched C 3 -C 20 or unsaturated C 2 -C 20 alkyl hydrocarbon-based radical, an aryl radical optionally substituted with one or more hydroxyl groups and/or with one or more C 1 -C 8 alkoxy radicals; R is a hydrogen atom, a saturated linear C 1 -C 20 or branched C 3 -C 20 or unsaturated C 2 -C 20 alkyl hydrocarbon-based radical, an aryl radical or a saturated C 1 -C 8 alkyl radical containing an aryl substituent optionally substituted with one or more hydroxyl groups and/or with one or more C 1 -C 8 alkoxy radicals; R optionally bears one or more substituents selected from among OR 2 , SR 2 , NR 2 R 3 and COOR 2 in which: R 2 is a hydrogen atom or a saturated linear C 1 -C 5 or branched C 3 -C 5 or unsaturated C 2 -C 5 hydrocarbon-based radical, or an aryl radical; R 3 is a hydrogen atom, a saturated linear C 1 -C 5 or branched C 3 -C 5 or unsaturated C 2 -C 5 hydrocarbon-based radical, an aryl radical, or an acetyl radical; with the proviso that R and R 1 may together form a ring member selected from among pyrrolidine, pyrroline, piperidine, piperazine, morpholine, thiomorpholine and azepine; and also the salts, chelates, solvates and optical isomers thereof, formulated into a topically applicable, cosmetically/dermatologically acceptable support therefor.
