COMPOSITION CONTAINING A DIBENZOYLMETHANE DERIVATIVE AND AN -ALKYLSTYRENE DIMER, UV STABILISING METHOD

摘要

The invention concerns a cosmetic or dermatological composition, for topical use, in particular for solar protection of the skin and hair. The invention is characterised in that it comprises in a cosmetically acceptable carrier: (a) 0.1 to 20 wt. % of a UV filter derived from dibenzoylmethane; and (b) 0.1 to 20 wt. % of a particular -alkylstyrene dimer. The invention also concerns a novel method for enhancing the stability of at least a dibenzoylmethane derivative towards UV radiation which consists in associating with said dibenzoylmethane derivative an efficient amount of at least a particular -alkylstyrene dimer.
