Biological Activity
Avobenzone (Parsol 1789) is a lipophilic dibenzoylmethane derivative and broad-spectrum ultraviolet A (UVA) absorber. It absorbs UVA radiation across thewavelength range to mitigate light-induced cellular oxidative damage and cutaneous phototoxicity. Under solar irradiation, avobenzone undergoes photo-isomerization and photo-degradation, which can be altered in combination with mineral UV absorbers like titanium dioxide. Co-formulation strategies stabilize the molecule, maintaining its photoprotective efficacy against UVA-mediated oxidative stress pathways. [1]
