Product Description

What is Avobenzone?

Avobenzone is an oil soluble ingredient used in sunscreen products to absorb the full spectrum of UVA rays.
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 provides strong absorption through a large portion of the UVA spectrum including the majority of the UVA I range with peak absorption at 360 nm. Photostability refers to the ability of a molecule to remain intact with irradiation. It is potentially a problem with all UV filters, but particularly with the use of avobenzone. This effect may degrade other sunscreens in a formulation including octyl methoxycinnamate. Octocrylene and some of the newer sunscreens including BEMT stabilized avobenzone. Non-UV filters such as diethylhexyl 2,6 naphthalate may also be used. These molecules function as triplet-triplet quenchers. Overall formulation with avobenzone is therefore particularly critical.
