Sulisobenzone (benzophenone-4) is a sunscreen ingredient; can cause skin and eye irritation. Does not penetrate the skin to a large degree, but enhances the ability of other chemicals to penetrate. Benzophenone ingredients absorb and dissipate UV radiation, which serves to protect cosmetics and personal care products. As part of sunscreen products, which are OTC drugs in the United States, Benzophenone-3 (Oxybenzone) and Benzophenone-4 (Sulisobenzone) protect the skin from the harmful effects of the sun.
