AAKO name AakoSun BTZ

Product description

AakoSun BTZ is better known as Diethylhexyl Butamido Triazone. It is an organic, oil-soluble sun filter that absorbs UV-B radiation. Requires only very small concentrations to achieve a high Sun Protection Factor (SPF). Diethylhexyl Butamido Triazone is being used in a wide range of cosmetic products to provide an appropriate Sun Protection Factor (SPF) in sunscreens or to protect cosmetics against UV radiation. It is hardly absorbed by the skin, rarely leads to irritation, causes no allergic reactions and there is no evidence of any (geno)toxic or carcinogenic effect. Very soluble in cosmetic emollients an can readily be incorporated in the oily phase of emulsions. Because of its hydrophobic nature it’s particularly suitable for water-repellent and water-resistand formulations.

Diethylhexyl Butamido Triazone is also known under the name Iscotrizinol.



  • Very effective UV-B filter.
  • Super photostable UV filter. Only loses 10% of it’s SPF protection ability in 25 hours.
