  • Applications

    Dl-alpha-tocopherol acetate (CAS 52225-20-4) is an ester of tocopherol (vitamin E) widely used in cosmetics and personal care as an antioxidant and skin-conditioning agent, helping to stabilize oil- and emulsion-based formulations and extend product shelf life. It also serves as a fat-soluble vitamin source for foods and animal feeds, providing nutritional value while contributing antioxidant protection to fats and oils during processing. In industry, it may function as an antioxidant/stabilizer in polymer formulations, coatings, and inks, and it can appear as an excipient in certain pharmaceutical topical dosage forms. Use is subject to local regulations and formulation limits.
