Patent ID: 8268294

Claim:
A photostabilized sunscreen or dermatological composition comprising a retinoid compound that reaches an excited state or fluoresces when exposed to UV radiation from UV-induced photodegradation in an amount of about 0.001% to about 5% by weight and a compound of formula (I) in an amount of at least 0.01% by weight, based on the total weight of the composition to quench excited state energy from the retinoid compound and transfer the excited state energy from the retinoid compound to the compound of formula (I), wherein the compound of formula (I) is 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 or R 2 is hydrogen; and R 3 is a straight or branched chain C 1 -C 30 alkyl radical, thereby photostabilizing the retinoid compound.
