Description
Ethylhexyl triazone (CAS 88122-99-0) is a triazine-based UVB filter used in sun care and cosmetic formulations, where it is registered under EC 402-070-1. It is commercially available under trade names including UVT 150, KOPTRIZON, and UVINUL 150. It carries no assigned E-code and is classified under HS code 29336990.
In sun care products, ethylhexyl triazone absorbs UVB radiation in the 280-320 nm range by converting photon energy into heat, protecting both the skin and co-formulated actives from photodegradation. In coatings and polymer systems, it functions as a UV stabilizer that limits photooxidative chain scission, extending substrate service life under outdoor exposure conditions.
Ethylhexyl triazone is supplied in solid and solution grades and is compliant with EU Cosmetics Regulation Annex VI, which permits its use as a UV filter up to 5% in finished products. Procurement quantities are available from laboratory scale through bulk, with documentation supporting REACH compliance.
