131-57-7 Cosmetic UV Absorber Benzophenone-3
Introducton and Application:

Oxybenzone is used in plastics as an ultraviolet light absorber and stabilizer. It is used, along with otherbenzophenones, in sunscreens, hair sprays, and cosmetics because they help prevent potential damage from sunlight exposure. It is also found, in concentrations up to 1%, in nail polishes. Oxybenzone can also be used as a photostabilizer for synthetic resins. Benzophenones can leach from food packaging, and are widely used as photo-initiators used to start a chemical that dries ink faster.


As a sunscreen, it provides broad-spectrum ultraviolet coverage, including UVB and short-wave UVA rays. As aphotoprotective agent, it has an absorption profile spanning from 270 to 350 nm with absorption peaks at 288 and 350 nm. It is one of the most widely used organic UVA filters in sunscreens today. It is also found in nail polish, fragrances, hairspray, and cosmetics as a photostabilizer. Despite its photoprotective qualities, much controversy surrounds oxybenzone because of its possible hormonal and photoallergenic effects, leading many countries to regulate its use.
