The present invention relates to a cosmetic composition comprising the combination i) of at least one screening agent of the dibenzoylmethane derivative type and ii) of at least one specific merocyanine dicyano or cyanoacetate derivative. It 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.
Disclosed are compounds of formula (1) and (2) and/or E/E-, E/Z- or Z/Z geometrical isomer forms thereof; wherein R1-R5, R1-R11 and A are defined as in description. The compounds are used as UV absorbers for protecting household products from photolytic and oxidative degradation, as plastic additives, preferably for food and pharmaceutical packaging applications, for preventing photo-degradation of food by incorporation of the compounds of formula (1′) and/or (2′) into transparent food containers, for protection of UV-A sensitive drugs from photo-degradation by incorporation of UV absorber in transparent blister foils or transparent pharmacy containers, as additives for photographic and printing applications, as additives for electronic applications and protecting the ingredients in agriculture applications.
