Description
DL-alpha-tocopherol (CAS 10191-41-0) is the synthetic racemic form of Vitamin E, commercially available under trade names including Ronotec 201, Ronotec DF 120, and Ephanyl. It is classified under HS code 29362800 and registered under EC 233-466-0. No E-number designation applies to this synthetic form.
In food and feed applications, DL-alpha-tocopherol retards lipid oxidation by donating hydrogen atoms to free radicals, interrupting chain reactions that cause rancidity in fats and oils. In plastics processing, it functions as a heat stabilizer by scavenging peroxy radicals generated during high-temperature extrusion, extending polymer service life. Personal care formulators incorporate it as a skin protectant and secondary UV absorber in emollient systems.
This ingredient is supplied in compliance with Ph.Eur. and FCC monograph specifications and falls under REACH registration obligations for EU import and manufacture. It is typically available in bulk liquid format suited for industrial dispensing. Procurement teams should confirm grade specification against the intended application standard prior to ordering.
