Oxybenzone
What is Oxybenzone?
Oxybenzone, or benzophenone-3, is a synthetic organic chemical compound serving as a key ingredient in sunscreen and cosmetic products designed for sun protection. Classified as a chemical UV filter, it primarily targets UVB and some UVA radiation. In formulations, it functions by absorbing ultraviolet rays that contact the skin, converting their energy into minimal heat through a photochemical process, thus reducing penetration to deeper skin layers. This lipophilic substance integrates well into emulsions like creams, gels, and sprays, often improving product spreadability and photostability. Commonly found in water-resistant sunscreens, it helps maintain efficacy during swimming or sweating. Its molecular structure enables solubility in oils, aiding even distribution on the skin surface while providing a non-greasy feel in many products.
