Patent ID: 7754191

Claim:
A method of quenching fluorescence and excited state energy of a naphthalate compound that is subjected to UV-radiation in an amount sufficient to cause the naphthalate compound to reach an excited state and fluoresce, comprising adding to the naphthalate compound, in a sunscreen composition, a fluorescence quenching amount of a compound of formula (1): wherein R 1 is an alkoxy; R 2 is an organic linker; R 3 is selected from a group consisting of a straight or branched C 1 -C 30 alkyl, a straight or branched C 1 -C 30 alkenyl, a straight or branched C 1 -C 30 alkynyl, and a polymer; k is either zero or one; l is either zero or one, wherein the sum of k+l is one; and m is an integer in a range from zero to about twenty.
