What is Avobenzone?

Avobenzone (INCI: Butyl Methoxydibenzoylmethane) is a chemical UV filter that is the only FDA-approved broad-spectrum UVA-absorbing active sunscreen ingredient in the US that covers the full UVA spectrum (320โ€“400 nm). It is inherently photounstable and must be combined with photostabilizers.

Why is Avobenzone used in personal-care products?

Provides broad UVA protection in US-approved sunscreen formulations. It is a critical component of broad-spectrum sunscreen products, often paired with octocrylene, ensulizole, or diethylhexyl 2,6-naphthalate (DEHN) as photostabilizers.

Is Avobenzone dangerous? Documented risks

Avobenzone is effective and considered safe at approved concentrations (up to 3% in US OTC sunscreens). A 2019 FDA study found that several sunscreen actives including avobenzone were systemically absorbed above the 0.5 ng/mL threshold after repeated use, triggering a call for additional safety data. This does not indicate harm, but the FDA requested more studies under its proposed sunscreen monograph. Current evidence supports its continued safe use. No clear endocrine disruption or carcinogenicity at human exposure levels is established.

How to avoid Avobenzone: safer alternatives

Bisoctrizole (Tinosorb M, EU-approved only) or bemotrizinol (Tinosorb S, EU-approved only) are newer, more photostable UVA filters, but these are not FDA-approved in the US.

Frequently asked questions about Avobenzone

Is avobenzone safe?

Current evidence supports safe use at approved concentrations. The 2019 FDA absorption study raised questions about long-term high-use scenarios, but no adverse health outcomes have been established. The FDA continues to recommend using sunscreen.

Does avobenzone degrade in sunlight?

Yes. Avobenzone is photounstable and degrades on UV exposure. Modern formulations include photostabilizers (like octocrylene or diethylhexyl 2,6-naphthalate) to extend its protection lifetime.

Is avobenzone approved in the EU?

Yes. It is approved as a UV filter in EU cosmetics at up to 5%, listed in Annex VI.
