octyl triazone is a highly effective uv-b filter with an exceptionally high absorptivity of over 1500 at 314nm. because of its high a1/1 value, only small concentrations are required in cosmetic suncare preparations, to achieve a high spf value. concentrations up to 3% are recommended.

besides the polar nature of this product 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. ethylhexyl triazone can crystallize after prolonged storage, as a result of supersaturation.

octyl triazone has very good light stability. it remains practically unchanged,even when it is exposed to intense radiation.
