UV Absorber 9 is also known as Oxybenzone or benzophenone-3 which is an organic compound. It is a white solid that is readily soluble in most organic solvents. Oxybenzone belongs to the class of aromatic ketones known as benzophenones. It is a component of many sunscreen lotions.
UV Absorber 9 is used in plastics as an ultraviolet light absorber and stabilizer. It is used, along with other benzophenones, 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. UV Absorber 9 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, UV Absorber 9 provides broad-spectrum ultraviolet coverage, including UVB and short-wave UVA rays. As aphotoprotective agent, UV Absorber 9 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.
