Bisoctrizole
Bisoctrizole (USAN[1], Tinosorb® M, INCI Methylene Bis-Benzotriazolyl Tetramethylbutylphenol) is a chemical which is added to sunscreens to absorb UV rays. It's marketed by Ciba Specialty Chemicals. Additional recommended knowledgeBisoctrizole 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. It's produced as small particles (< 200 nm)[2], like microfine zinc oxide and titanium dioxide. And it is organic like most sunscreen actives. It is added to the water phase of a sunscreen as a 50% suspension, while mineral micropigments are usually added to the oil phase. Bisoctrizole shows very little photodegradation and has a stabilizing effect on other UV absorbers, octyl methoxycinnamate (octinoxate) in particular. Unlike some other organic sunscreen actives, it shows no estrogenic effects in vitro.[3] Bisoctrizole is not approved by the FDA, but is approved in the EU and other parts of the world.[4][5][6] See alsoReferences
