Diethylhexyl Butamido Triazone
INCI · Diethylhexyl Butamido Triazone · also Iscotrizinol, Uvasorb HEB
Overview
A large, oil-soluble UVB filter sold under names including Iscotrizinol and Uvasorb HEB. Its molecular size keeps it on the skin surface, and it is photostable enough to be used as a partner that helps hold less stable filters together.
Who it's for
Sunscreens made for regions where it is approved, particularly high-protection formulas that need strong UVB absorption without a heavy feel.
Cautions
It covers UVB, so UVA protection has to come from elsewhere in the formula; read the broad-spectrum or PA marking rather than the filter list. Approval is regional and it is not available in every market, which is one reason sunscreen formulas differ so much between countries.
