DIPHENYL CARBOMETHOXY ACETOXY NAPHTHOPYRAN.

Optional CAS 169682-22-8 / UV ABSORBER

DIPHENYL CARBOMETHOXY ACETOXY NAPHTHOPYRAN is a distinctive photochromic agent that changes color visibly upon exposure to ultraviolet radiation. It serves as both a UV absorber to protect cosmetic product integrity and a novel visual indicator for UV exposure on human skin.

UV Absorber Photochromic Agent Visual UV Indicator

Science

This compound acts as a UV absorber, shielding cosmetic formulations from degradation caused by UV light. Its primary mechanism on skin involves a ring-opening reaction triggered by UVA, UVB, and/or UVC rays, generating colored merocyanine dyes. This dynamic color change provides a direct, visual indication of UV radiation exposure.
