Method for photostabilizing a dibenzoylmethane derivative using a merocyanine sulphone derivative; photoprotective cosmetic compositions containing said combination

摘要

Photostabilization of dibenzoylmethane derivatives against UV radiation, comprises contacting dibenzoylmethane derivative with a merocyanine sulfonic derivative. An independent claim is included for a composition comprising at least an UV filter, preferably dibenzoylmethane derivative and at least a merocyanine sulfonic derivative in a support.
