Abstract
A method of testing a compound for its capability of quenching singlet excited state energy from a photon-excited photoactive compound, thereby photostabilizing said photoactive compound, comprising mixing: (1) a composition comprising a photoactive compound in a solvent and determining the degree of fluorescence of said composition (1) by exposing the composition (1) to UV radiation in an amount sufficient for the photoactive compound to reach an electronic singlet excited state, and (2) a mixture comprising said photoactive compound with a test compound in a solvent, and determining the degree of fluorescence of said mixture (2) by exposing the mixture to UV radiation to the same degree as composition (1), and comparing the degree of fluorescence of composition (1) with mixture (2).
