Iscotrizinol

Iscotrizinol (CAS 154702-15-5) is a triazine-based UV absorber also known by the trade names Uvasorb HEB and the abbreviations HEB and UV HEB, with EC number 421-450-8. It is registered under REACH and carries the molecular formula C44H59N7O5, classifying it within the broader dioctylbutamidotriazone family of UV filters.

In sunscreen and personal care formulations, iscotrizinol absorbs UVB radiation in the 290-320 nm range, converting photon energy to heat and preventing photodegradation of the formulation and skin damage. In industrial coatings and adhesive systems, it functions as a light stabilizer that retards polymer chain scission and colour shift caused by prolonged UV exposure.

Iscotrizinol is supplied as a solid and is compliant with REACH registration requirements applicable to the EU market. It is listed under HS code 2933690000 for customs classification purposes. Procurement teams should confirm grade specifications and packaging formats directly with the supplier to match application requirements.
