Avobenzone
Avobenzone is a chemical compound commonly used in sunscreen products to absorb ultraviolet (UV) rays from the sun. It belongs to a class of organic compounds known as benzophenones. Avobenzone is effective in absorbing UVA (ultraviolet A) rays, which are responsible for causing skin aging and contribute to the development of skin cancer.

Pure 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 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.
