Bisoctrizole (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. It is a broad-spectrum ultraviolet radiation absorber, absorbing UVB as well as UVA rays. It also reflects and scatters UV.

Bisoctrizole (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. It is a broad-spectrum ultraviolet radiation absorber, absorbing UVB as well as UVA rays. It also reflects and scatters UV.
Bisoctrizole is what is termed a hybrid UV absorber, which has been described as an organic UV filter produced in microfine organic particles (< 200 nm), like microfine zinc oxide and titanium dioxide. Where other organic UV absorbers dissolved in either the oily or aqueous phases, bisoctrizole dissolves poorly in both.
