Photostabilization of coenzyme Q compounds with alkoxycrylene compounds

摘要

A method of reducing photodegradation of a coenzyme Q10 compound when exposed to UV radiation in a composition containing said coenzyme Q10 compound comprising combining with said coenzyme Q10 compound a compound of formula (I) in an amount effective to quench singlet excited state energy from the coenzyme Q10 compound and transfer the singlet excited state energy from the coenzyme Q10 compound to the compound of formula (I), wherein one of R1 and R2 is a straight or branched chain C1-C30 alkoxy radical, and the non-alkoxy R1 or R2 is hydrogen; and R3 is a straight or branched chain C1-C30 alkyl radical, thereby photostabilizing the retinoid compound.
