Bisoctrizole is a broad-spectrum ultraviolet radiation absorber, absorbing UVB as well as UVA rays. It also reflects and scatters UV. Bisoctrizole is a hybrid UV absorber, the only organic UV filter produced and microfine organic particles (< 200 nm),〔(Ciba TINOSORB M )〕 like microfine zinc oxide and titanium dioxide. Where other organic UV absorbers need to be dissolved in either the oil or water phase, bisoctrizole dissolves poorly in both. Bisoctrizole is added to the water phase of a sunscreen as a 50% suspension, whereas mineral micropigments are usually added to the oil phase. The bisoctrizole particles are stabilized by the surfactant decyl glucoside. Bisoctrizole shows very little photodegradation and has a stabilizing effect on other UV absorbers, octyl methoxycinnamate (octinoxate) in particular. When formulated into a sunscreen, bisoctrizole has minimal skin penetration. Unlike some other organic sunscreen actives, it shows no estrogenic effects in vitro. Bisoctrizole is not approved by the U.S. Food and Drug Administration (FDA), but is approved in the EU and other parts of the world.〔(Manage Account - Modern Medicine )〕〔(CL1976L0768EN0150010.0001 1..107 )〕〔(Australian Regulatory Guidelines for OTC Medicines - Chapter 10 )〕 ==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「Bisoctrizole」の詳細全文を読む スポンサード リンク
