Bemotrizinol

Properties:

Bemotrizinol (Tinosorb S) is an asymmetrically substituted 1,3,5-triazine that is used as a broad-spectrum UV filter in sunscreens . The triazine core substituted with functionalized aromatics is responsible for UV absorption , and the hydrophobic 2-ethylhexyloxyphenol substituents are responsible for oil solubility and water resistance in dermatological and cosmetic preparations. Bemotrizinol has a broad UV absorption spectrum with absorption maxima λmax in the UV-B range at 310 nm and in the UV-A range at 343 nm. It is usually used in combination with other UV filters that are stabilized by BEMT.
