Benzophenone is an organic compound that consists of a ketone group attached to two phenyl groups. It is commonly used in various industries, including cosmetics and plastics, as a UV filter to protect products from the harmful effects of ultraviolet light. This helps prevent degradation and discoloration in items like sunscreens and lotions. In addition to its use in personal care products, benzophenone is also utilized in the production of certain types of polymers and coatings. Its ability to absorb UV radiation makes it valuable in enhancing the stability and longevity of materials exposed to sunlight, such as polyethylene and polycarbonate.
