<unk>  (INN/USAN, marketed by BASF as Tinosorb M, by DSM Nutritional Products as Parsol Max , by Everlight Chemical as Eversorb M, and by MPI as Milestab 360, INCI methylene bis-benzotriazolyl tetramethylbutylphenol) is a phenolic benzotriazole that is added to sunscreens to absorb UV rays.<unk>  is a broad-spectrum ultraviolet radiation absorber, absorbing UVB as well as UVA rays. It also reflects and scatters UV.<unk>  is a hybrid UV absorber, an organic UV filter produced in microfine organic particles (< 200 nm), like microfine zinc oxide and titanium dioxide. Where other organic UV absorbers need to be dissolved in either the oil or water phase,<unk>  dissolves poorly in both and is applied as invisible particle.<unk>  is added to the water phase of a sunscreen as a 50% suspension, whereas mineral micropigments are usually added to the oil phase. The<unk>  particles are stabilized by the surfactant decyl glucoside.<unk>  shows very little photodegradation and has a stabilizing effect on other UV absorbers, octyl methoxycinnamate (octinoxate) in particular. When formulated into a sunscreen,<unk>  has minimal skin penetration and it shows no estrogenic effects in vitro.<unk>  is not approved by the U.S. Food and Drug Administration (FDA), but is approved in the EU and other parts of the world.
