Description:
D-alpha Tocopheryl Acetate is a colorless to yellow clear oily liquid, nearly odorless. Usually, natural tocopheryl acetate is produced by esterification of acetic acid and natural d-alpha tocopherol, and then diluted to various content specifications with edible sunflower oil.
Function:
A natural tocopherol and one of the most potent antioxidant tocopherols. It exhibits antioxidant activity by virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus. It has four methyl groups on the 6-chromanol nucleus. The natural d form of alpha-tocopherol is more active than its synthetic dl-alpha-tocopherol racemic mixture.
Application:
TPN, Pharmaceutical, Food, Dietary Supplement, Cosmetics, Nutrition, Health Care, Pet food etc.
