Process for photostabilising a dibenzoylmethane derivative with an arylalkyl benzoate derivative and an amide oil; sunscreening cosmetic compositions

摘要

Photostabilization of at least a dibenzoylmethane derivative (I) against UV radiation, comprises linking (I) with an arylalkyl benzoate derivative (II) and oil (III) having at least an amide derivative in the structure. Independent claims are also included for: (1) topical cosmetic or dermatological composition (A) comprising at least UV filter of dibenzoylmethane derivative type, (II) and (III) in a medium ; and (2) use of (II) and (III) in (A) comprising (I) to improve the stability of (I) against of UV radiations.
