Oxybenzone-d 5 is the deuterium labeled Oxybenzone. Oxybenzone (Benzophenone 3) is a commonly used UV filter in sun tans and skin protectants. Oxybenzone act as endocrine disrupting chemicals (EDCs) and can pass through the placental and blood-brain barriers. Benzophenone-3 impairs autophagy , alters epigenetic status, and disrupts retinoid X receptor signaling in apoptotic neuronal cells.
