УВТ-150

Описание

As a new type of triazine UV absorber, ethylhexyl triazone has a large molecular structure and high UV absorption efficiency, has a broad-spectrum sunscreen effect, is the most powerful oil-soluble UV-B absorber on the market today, has high photostability and prevents UV-B-induced immunosuppression. It has strong water resistance and a good affinity for skin keratin.

Использование

ethylhexyl triazone is the InCI name for octyltriazone. It is a uV filter and absorber. Clinical studies show high photostability and very high uVB-absorption capacity, particularly when compared to other popular uV filters. Studies also indicate that even low concentrations of ethylhexyltriazone in a sun care preparation can contribute significantly to the final product’s SPF. It appears to perform particularly well in synergy with zinc oxide.
