Avobenzone is a synthetic UV absorber that provides full UVA and UVB protection against photo-causative skin cancer.
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.
