Photostabilization of resveratrol with alkoxycrylene compounds

摘要: The photostabilizing electronic excited state energy—particularly singlet energy from resveratrol compounds—has been found to be readily transferred (accepted by) α-cyanodiphenylacrylate compounds having an alkoxy radical in the four (para) position (hereinafter “alkoxycrylenes”) on one of phenyl rings formula (I): wherein R1 and R2 is a straight or branched chain C1-C30 radical, preferably C1-C8, more methoxy, non-alkoxy hydrogen; R3 alkyl C2-C20. alkoxycrylene (I) significantly increase photostability composition by at least 3-fold as much 10-fold greater. ability stabilize compound concentration dependent, with amount photostabilization increasing compound.
