Photostabilization of UV filtering systems by use of block copolymers, useful for photo-protective cosmetic compositions

摘要

Stabilization vis-a-vis UV radiation of a filtering system comprising a dibenzoylmethane derivative, by association with an effective amount of an amphiphilic block copolymer comprising a non-ionic hydrophilic block and a hydrophobic block. An Independent claim is also included for the stabilizing composition.
