It is marketed as Tinosorb S by BASF and as Escalol S by Ashland Inc. A recent development is Tinosorb S Aqua, which is bemotrizinol in a PMMA matrix dispersed in water. This makes it possible to add bemotrizinol to the water phase.〔Tinosorb S Aqua info()〕 Bemotrizinol is a broad-spectrum UV absorber, absorbing UVB as well as UVA rays. It has two absorption peaks, 310 and 340 nm. It is highly photostable. Even after 50 MEDs (minimal erythemal doses), 98.4% remains intact. It helps prevent the photodegradation of other sunscreen actives like avobenzone. Bemotrizinol has strong synergistic effects on the SPF when formulated with bisoctrizole, ethylhexyl triazone or iscotrizinol.〔http://www.ciba.com/tinosorb-s_brochure.pdf〕 It is the most effective UV absorber available measured by SPF, based on the maximum concentration permitted by European legislation. Bemotrizinol is not approved by the United States Food and Drug Administration, but is approved in the European Union since the year 2000〔.(SpringerLink - Journal Article )〕 and other parts of the world, including Australia.〔NEW-WAVE SUNSCREENS: Active ingredient makers are frustrated by the long list of sunscreens and UV-A testing protocols that are still awaiting FDA decisions, ''Chemical & Engineering News'', April 11, 2005, Volume 83, Number 15, pp. 18–22. (Online version )〕〔(Australian Regulatory Guidelines for OTC Medicines - Chapter 10 )〕 Unlike some other organic sunscreen actives, it shows no estrogenic effects in vitro. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bemotrizinol」の詳細全文を読む スポンサード リンク
