WebAug 24, 2013 · It’s one of the safest chemical sunscreen agents available – a study by the Scientific Committee on Consumer Products (a scientific European Committee that reviews cosmetic safety) showed that it does not pose any phototoxicity, photoallergenic, photomutagenicity, or photoclastogenicity risks. It’s a very effective UVA absorber, and … WebMay 1, 1987 · The results of these studies indicate that photochemical analysis of compounds is a good predictor of in vitro phototoxicity, but not necessarily, photoclastogenicity. Further evidence from photostability experiments suggests that this is due to the differences in UVR irradiance and exposure conditions between the two assays.
