ultraviolet screen
Oxybenzone is an organic compound used in sunscreens. Oxybenzone is used as an ingredient in sunscreen and other cosmetics because it absorbs UVB and short-wave UVA (ultraviolet) rays. Oxybenzone was one of the first compounds incorporated into sunscreen formulations to offer enhanced UVA protection because its absorption spectrum extends to less than 350 nm.
Sunscreen. UV stabilizer
Ultraviolet light absorber and stabilizer, especially in plastics and paints.
oxybenzone (benzophenone-3) is the drug name for an FDAapproved uV filter and absorber.
Drug Function and Efficacy
UV absorber, sunscreen agent, photoprotective
