Bisoctrizole (INN[1]/USAN,[2] marketed byBASF asTinosorb M, by DSM Nutritional Products asParsol Max, by Everlight Chemical asEversorb M, and by MPI asMilestab 360,INCI methylene bis-benzotriazolyl tetramethylbutylphenol) is aphenolic benzotriazole that is added tosunscreens to absorbUV rays.[3] It is a broad-spectrumultraviolet radiation absorber, absorbing UVB as well as UVA rays.[3] It also reflects and scatters UV.[citation needed]
