Avobenzone

Avobenzone

Avobenzone is a chemical compound that is often used in sunscreen products due to its ability to absorb ultraviolet (UV) light. It is also known by its systematic name, Butyl Methoxydibenzoylmethane, and is classified as a dibenzoylmethane derivative.

Chemical Properties

Avobenzone is a yellowish crystalline powder with a slight characteristic odor. It is soluble in oil and alcohol, but insoluble in water. The compound has a molecular formula of C20H22O3 and a molecular weight of 310.39 g/mol. It absorbs UV light in the range of 310 to 400 nm, with a peak absorption at 360 nm.

Uses

The primary use of Avobenzone is in sunscreens and other skincare products as a UV filter. It is capable of absorbing both UVA and UVB rays, thus providing broad-spectrum protection against harmful UV radiation. Avobenzone is often combined with other sunscreen agents such as Octocrylene and Oxybenzone to enhance its photostability and efficacy.

Safety and Regulations

Avobenzone is generally considered safe for use in sunscreens and has been approved by health authorities worldwide, including the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA). However, some studies have raised concerns about potential skin irritation and the possibility of the compound penetrating the skin and entering the bloodstream.
