Avobenzone is a dibenzoyl methane derivative. It is an oil-soluble ingredient used in sunscreen products. However, it is susceptible to photodegradation, and therefore it is important that avobenzone be combined with photostabilizers in the final sunscreen product. It has an absorption maximum of 357 nm. It was granted a patent in 1973 and received EU approval in 1978. The FDA gave its approval in 1988.

Avobenzone is a UV rays blocker used in sunscreen. Avobenzone is a topical UV protector with a broad spectrum of protection against UV radiation. It inhibits UVA I, UVA II, and UVB wavelengths, which reduces the damaging effects of UV rays on skin.
Avobenzone is a UVA solar filter and is used in sunscreen lotions and cosmetic formulations. It protects the skin from sunburn-causing UV rays. Using sunscreen products containing Avobenzone, may also help reduce long-term sun damage such as premature aging of the skin and skin cancer.
Q. Is avobenzone safe in sunscreen?
Avobenzone degrades rapidly in the sun and provides only around 30 minutes of sun protection. After only an hour in the sun, it loses 36% of its ability to absorb ultraviolet light.
Q. Does avobenzone cause cancer?
There is no evidence available regarding the carcinogenic nature of Avobenzone.
Q. Is avobenzone safe during pregnancy?
It is recommended to avoid the use of products containing avobenzone during pregnancy due to the possible risk of harm to the developing foetus.
Q. Is avobenzone the same as oxybenzone?
Q. Is avobenzone the same as benzene?
Avobenzone is an oil-soluble ingredient derived from dibenzoylmethane that is used to absorb ultraviolet radiation in sunscreen products, whereas Benzene is an aromatic hydrocarbon with the formula C6H6 and the structure of alternating single and double bonds. Both are different organic compounds with different physical & chemical properties as well as applications.
