DefinitionThis section has been translated automatically.

Bemotrizinol is a substance with the empirical formula C38H49N3O5 which is almost insoluble in water but highly soluble in oils such as sesame oil; chemically it is a 1,3,5-triazine which is used as a broad-spectrum UV filter in sunscreens up to a 10% application form (in Japan only 3%).

General informationThis section has been translated automatically.

The triazine nucleus substituted with functionalized aromatics is responsible for UV absorption, the hydrophobic 2-ethylhexyloxyphenol substituents for oil solubility and water resistance in dermatological and cosmetic preparations. Bemotrizinol has a broad UV absorption spectrum with absorption maxima in the UV-B range at 310 nm and in the UV-A range at 343 nm. It is mostly used in combination with other UV filters (e.g. octocrylene, octylmethoxycinnamate, benzophenone-3, octocrylene, octylmethoxycinnamate, avobenzone) which are stabilized by BEMT (Benevenuto CG et al. 2015).
