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.
