DL-alpha-Tocopheryl Acetate

CAS: 52225-20-4

Overview

DL-alpha-Tocopheryl Acetate (CAS 52225-20-4 ), commonly referred to as alpha-tocopherol acetate, is the synthetic esterified form of Vitamin E used across food, cosmetic, and pharmaceutical manufacturing.

The acetate ester form offers superior stability compared to free tocopherol, making it the preferred choice for formulators working with oxidation-sensitive systems in various industrial applications.

In personal care and cosmetics, it functions as a skin-conditioning antioxidant in creams, serums, and sunscreens, where it protects both the formulation and the skin surface from oxidative degradation.

Food and dietary supplement manufacturers use it as a Vitamin E source in fortified products, protein powders, and infant formula, where its stability through processing and shelf life is a key consideration.

In pharmaceutical applications, it is incorporated into oral capsules, topical preparations, and injectable emulsions as the active Vitamin E component for therapeutic and nutritional purposes.

Animal nutrition producers use it in premixes and compound feeds to meet livestock Vitamin E requirements and support product stability during pelleting and long-term storage in agricultural settings.

DL-alpha-Tocopheryl Acetate is supplied as a clear, viscous oil or in dry, water-dispersible powder forms. Standard grades include USP , BP , Ph. Eur. , and food-grade specifications for global compliance.

Concentration variants such as 50% and 70% dry powder forms are commonly stocked alongside neat liquid material to meet the specific formulation needs of diverse manufacturing sectors.
