Tris-biphenyl triazine (INCI) is an organic compound used in sunscreens to absorb UVA and UVB radiation. It is marketed as Tinosorb A2B by BASF. Tris-biphenyl triazine is considered a broad-spectrum UV absorber, covering the UVA2 (320−340 nm) and UVB range (280−320 nm).[2][3][1][4]
Tris-biphenyl triazine is approved for use up to a maximum concentration of 10% as a UV filter in cosmetics in the EU and Australia.[2][5] It is not currently recognised or approved by the FDA.
