Oxybenzone

Oxybenzone (2-Hydroxy-4-Methoxy Benzophenone) is an aromatic organic compound and a derivative of benzophenone. Supplied by Actylis as a white to light yellow crystalline powder with a rose-like scent, it is soluble in most organic solvents but practically insoluble in water. Oxybenzone is commonly used as a raw material in the cosmetics and specialty chemicals industry, particularly in products like sunscreen and other skin cosmetics. It is valued for its ability to absorb ultraviolet (UV) rays, providing protection to the skin from sun damage.
