Ethylhexyl Triazone Powder

 

Ethylhexyl triazone powder is a UVA sunscreen agent, which is a chemical sunscreen agent. It is allowed to be used in sunscreens in the European Union, Australia, and Japan, and the dosage must not exceed 5%. However, the U.S. FDA has not yet approved its use.

 

The effective absorption wavelength of Ethylhexyl Triazone is between 290-320nm. When used in combination with Uvinul A Plus, the SPF value can be increased.

 

It is the oil-soluble absorber with the strongest UV-B absorption capacity. It has strong light stability, strong water resistance, and good affinity for skin keratin.
