Avobenzone
INCI: Butyl Methoxydibenzoylmethane
Also known as: BMDBM, Parsol 1789

Avobenzone is the most widely used UVA-1 protective UV filter. The EU permits it at up to 5% (Annex VI #8), and the US permits it at up to 3% under the OTC sunscreen monograph. Avobenzone is photo-unstable on its own and is typically stabilized by combining with octocrylene, oxybenzone, or other UV filters; the FDA's GRASE proposed rule classifies avobenzone differently from oxybenzone — FDA has not asked for additional safety data on avobenzone.
Regulatory status by market
| Market | Status | Detail | Source |
|---|---|---|---|
| European Union | Restricted | Max 5% as UV filter | Annex VI #8 |
| United Kingdom | Restricted | Max 5% | UK Cosmetics Regulation |
| United States | Conditionally permitted | Max 3% under OTC sunscreen monograph | 21 CFR 352 |
| Canada | Restricted | Approved sunscreen active | Health Canada Sunscreen Monograph |
Safety profile
Avobenzone has a strong safety record and is not on regulatory watch-lists in the same way as oxybenzone. Its primary formulation challenge is photo-degradation: without stabilizers, avobenzone loses ~50% of its UV-absorbing capacity within an hour of sun exposure. Brands routinely pair it with octocrylene, polysilicone-15, or DHHB for photostability.
Common uses
