Diethylhexyl Butamido Triazone (Iscotrizinol, Uvasorb HEB) is an organic, oil-soluble UVB filter that absorbs ultraviolet radiation primarily in the UVB range, providing photoprotection in sunscreen and daily-care formulations. It is highly photostable and substantive to skin, often combined with other filters for broad-spectrum coverage.
