Benzophenone-3 (BP-3) is primarily used as a UV filter and photostabilizer in cosmetics and personal care products. It's a chemical sunscreen ingredient that helps protect skin from the damaging effects of ultraviolet (UV) radiation, specifically UVB and UVA. Additionally, it's used in other products to prevent photodegradation and discoloration, like in some plastics, paints, and even food packaging.
