1.Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. 

2.It is a dibenzoylmethane derivative. Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol. 

3.Its ability to absorb ultraviolet light over a wider range of wavelengths than many organic sunscreen agents has led to its
use in many commercial preparations marketed as "broad spectrum" sunscreens. 

4.Avobenzone has an absorption maximu of 357 nm.
