Description

General description

Avobenzone is an UVA filter. It is used in sunscreen lotions and cosmetic formulations. It has maximum absorption at ca 340–350 nm, decreasing under UV irradiation resulting in loss of the UVA protecting effect. Its photostability is very sensitive as it is stable in polar protic solvent and is photolabile in nonpolar solvents.
