Bemotrizinol (CAS 187393-00-6) is a cosmetic active ingredient functioning as Broad-spectrum oil-soluble organic UV filter with dual absorption peaks at. NOAEL 1000 mg/kg bw/day (cross-referenced against ToxValDB ECHA IUCLID); EU Regulation 1223/2009 status: permitted, max 10%. Industrial safety data is also available in the chemical safety database. Same-CAS public records also appear in industrial chemical safety data.
Broad-spectrum oil-soluble organic UV filter with dual absorption peaks at approximately 310 nm and 340 nm. Photostabilizer for avobenzone and other photolabile filters via triplet-state energy dissipation through S1→S0 internal conversion pathway. High molecular weight of 627 Da results in minimal skin penetration and surface-film behavior.
US NotesFDA Proposed Administrative Order OTC000039 (December 2025) proposes GRASE status at up to 6%. Initiated by DSM-Firmenich Tier 1 OMOR (September 2024). FDA noted low skin absorption and rare skin irritation. GRASE determination anticipated by March 2026. If finalized, would be the first new Category I UV filter added to the US monograph. Final order may follow in mid-to-late 2026 before market availability.
