Ethylhexyl triazone (INCI) is an organic compound used in sunscreens to absorb UVB radiation. It is marketed as Uvinul T 150 by BASF. It has an absorption maximum of 314 nm.
Uvinul® T 150 is a highly effective UVB filter with exceptionally high absorptivity. Due to the very high absorbency only small concentrations are required in cosmetic suncare preparations, to achieve a high SPF value. The polar nature of Uvinul® T 150 gives it good affinity to the keratin in the skin, so that formulations in which it is used are particularly water-resistant. This property is further enhanced by its complete insolubility in water.
