D-α-Tocopheryl Acetate (CAS 58-95-7) Product Brief
1. Product Overview
D-α-Tocopheryl Acetate is a natural plant-derived, high-purity and high-activity form of Vitamin E Acetate, refined and purified from vegetable oil deodorizer distillate. After acetylation modification, the product overcomes the instability of natural tocopherol, featuring excellent oxidation resistance, non-discoloration during storage and superior formula compatibility. Compared with synthetic vitamin E, it possesses higher biological activity, better transdermal absorption and ultra-low impurity content. As a clean-label antioxidant, professional skin conditioning agent and high-grade nutritional fortifier, it is widely used in high-end cosmetics, pharmaceutical preparations, functional health foods and premium feed industries.
