Bemotrizinol (USAN[1], Tinosorb® S, INCI Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine) is an oil soluble chemical which is added to sunscreens to absorb UV rays. It's marketed by Ciba Specialty Chemicals. It is a broad spectrum UV absorber, absorbing UVB as well as UVA rays. Bemotrizinol is highly photostable. Even after 50 MED (minimal edemal dose) 98.4% remains intact. It helps prevent photodegradation of other sunscreen actives.[2]
Bemotrizinol is not approved by the United States Food and Drug Administration, but is approved in the European Union since the year 2000[3] and other parts of the world, including Australia.[4][5]
Unlike some other organic sunscreen actives, it shows no estrogenic effects in vitro.[6]
