COSMETIC COMPOSITION CONTAINING DIBENZOYLMETHANE DERIVATIVE AND 2-PYRROLIDINONE-4-CARBOXYLATE COMPOUND, AND PHOTOSTABILIZATION METHOD OF DIBENZOYLMETHANE DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a composition further improved in photochemical stability (or photostability) of a dibenzoylmethane derivative and in effects in the UV-A region. Ž

SOLUTION: The composition includes at least one UV-shielding system and further contains (a) at least one dibenzoylmethane derivative and (b) at least one 2-pyrrolidinone-4-carboxylate compound of formula (I) [wherein R1is a linear or branched 1-20C alkyl group; and R2is a linear or branched 1-20C alkyl group optionally bearing a 5C to 6C ring, a phenyl group, a benzyl group or a phenethyl group].
