Bemotrizinol is a UV filter that a U.S. sunscreen may now list as an active ingredient, at up to 6% of the product. FDA added it to the sunscreen rules on June 10, 2026, and called it the first new sunscreen active added since the late 1990s.

Four names, one ingredient

You may see it written four ways:

• Bemotrizinol, the name on a U.S. Drug Facts panel.
• BEMT, the short form used in reviews and on social media.
• Tinosorb S, a trade name.
• Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, the name ingredient lists use, including in Europe.

SPF Scout reads bemotrizinol, Tinosorb S and the long chemical name as one ingredient, so flagging one flags all three spellings. Its ingredient page is here.

What FDA decided

• The order. Final order OTC000039 added bemotrizinol to OTC Monograph M020, the rulebook for U.S. sunscreens. FDA's announcement and the Federal Register notice have the details.
• The limit. Up to 6% of the product.
• The forms. Oils, lotions, creams, gels, butters, pastes, ointments, sticks and sprays.
• The request. DSM Nutritional Products asked for it in September 2024. FDA proposed the order in December 2025 and took public comments until January 2026.

What makes it different

FDA says bemotrizinol protects against both UVA and UVB rays and has low levels of absorption through the skin. It is not new everywhere: the European Union has long allowed it as a UV filter in cosmetics, which is why it appears on so many European labels.

Where to find it on a label

On a U.S. sunscreen, look at the Active ingredients block at the top of the Drug Facts panel. A label that uses it prints a line such as Bemotrizinol 6%. These U.S. labels print it there:

• Neutrogena Ultra Sheer Daily Face Sunscreen SPF 70, at 6%.
• Neutrogena Clear Face Sunscreen SPF 60, at 6%.
• Ultra Violette Fave Screen SPF 50, at 5%.

Some labels print the long chemical name lower down instead, among the inactive ingredients. Either way, it is on the list a scan shows you.

What it does not tell you

A new active does not make one sunscreen better than another, and SPF Scout does not rank them. The SPF number and the Broad Spectrum claim on the front come from tests of the finished product, not from its ingredient list.

Whether you want to find bemotrizinol or would rather skip it, add it to your flags in SPF Scout and every scan shows whether a label lists it.

This result compares the currently stored ingredient list with ingredients you selected. It is not a prediction of whether your skin will react.
