What is Avobenzone ?
Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays. It is a dibenzoylmethane derivative. Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol. 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. Avobenzone has an absorption maximum of 357.
Avobenzone having phenyl ketone group and sterically hindered group in one molecule, is an oil 
soluble sunscreen agent that absorbs a wider range of UV wavelengths. It absorbs both UV-A 
(380-315 nm that is associated with long term skin damage) and UV-B (315-280 nm that causes 
sunburn) rays. Avobenzone is known as one of the most effective sunscreen ingredient.
APPLICATION
Avobenzone was introduced in the 1990s and is a common chemical sunscreen. Unlike other chemical sunscreens that just protect from the sunburn-causing UVB rays, avobenzone also protects from UVA rays, the rays that cause premature aging and skin cancer.
