COMPOSITION COMPRISING DIBENZOYLMETHANE SCREENING AGENT AND MEROCYANINE DICYANO OR CYANOACETATE DERIVATIVE; AND METHOD FOR PHOTOSTABILIZATION OF DIBENZOYLMETHANE SCREENING AGENT

摘要

PROBLEM TO BE SOLVED: To substantially further improve photochemical stability (or photostability) of dibenzoylmethane derivatives and their effectiveness in the UV-A region.SOLUTION: The present invention relates to a cosmetic composition comprising the combination of i) at least one screening agent of the dibenzoylmethane derivative type and ii) at least one specific merocyanine dicyano or cyanoacetate derivative. The present invention also relates to a method for the photostabilization, with regard to radiation, of at least one screening agent of the dibenzoylmethane derivative type by an effective amount of at least one specific merocyanine dicyano or cyanoacetate derivative.
