tcsc0033785 Ethylhexyl triazone

Ethylhexyl triazone is an approved ultraviolet-B (UV-B) chemical filter for commercial sunscreens.

In Vitro: One property of Ethylhexyl triazone (EHT) is its large molecular weight (823.07 g/mol); such filters are unlikely to penetrate the skin, thereby reducing effects associated with such skin penetration. It displays a broad absorption profile across the UV-B region, with a maximum absorption at ~311 and ~313 nm for Ethylhexyl triazone-dioxane and Ethylhexyl triazone-methanol, respectively^[1].
