CAS 131-57-7 oxybenzone UV9 Introduction :

UV-9 is a high-efficienct UV radiation absorbing agent, capable of effectively absorbing UV radiation of 290-400 nm wavelength ,but it almost does not absorb visible light, particularly applicable to light-colored transparent products. It is well stable to light and heat, not decomposable below 200°C, applicable to paint and various plastic products,particular effective to polyvinyl chloirde, polystyrene, polyurethane, acrylic resin, light-colored transparent furniture, as well as to cosmetics , with the dosage of 0.1-0.5%.

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.
