219861-73-1 Usage
General Description
2,2',3'-Trihydroxy-4,6-dimethoxybenzophenone, also known as oxybenzone, is a chemical compound commonly used in sunscreen and other skincare products as a UV-filtering agent. It absorbs and dissipates UV radiation, thus protecting the skin from sun damage. Oxybenzone is a benzophenone derivative with three hydroxy groups and two methoxy groups, which contribute to its UV-absorbing properties. However, concerns have been raised about its potential health and environmental effects, leading to bans on oxybenzone in certain regions. It is important for consumers to be aware of the potential risks associated with oxybenzone and to consider using alternative sunscreen products.
