Patent ID: 8257687

Claim:
A method of reducing photodegradation of a coenzyme Q 10 compound when exposed to UV radiation in a cosmetic or dermatological composition containing said coenzyme Q 10 compound comprising combining with said coenzyme Q 10 compound in an amount of at least 0.01% by weight with a compound of formula (I) in an amount of at least 0.1% by weight, based on the total weight of the composition to quench excited state energy from the coenzyme Q 10 compound and transfer the singlet excited state energy from the coenzyme Q 10 compound to the compound of formula (I), wherein one of R 1 and R 2 is a straight or branched chain C 1 -C 30 alkoxy radical, and the non-alkoxy R 1 and R 2 is hydrogen; and R 3 is a straight or branched chain C 1 -C 30 alkyl radical.
