D-alpha-tocopheryl acetate appears as odorless off-white crystals. Darkens at 401° F. (NTP, 1992)|Alpha-Tocopherol acetate is a tocol.|Alpha-tocopherol is the primary form of vitamin E that is preferentially used by the human body to meet appropriate dietary requirements. In particular, the RRR-alpha-tocopherol (or sometimes called the d-alpha-tocopherol stereoisomer) stereoisomer is considered the natural formation of alpha-tocopherol and generally exhibits the greatest bioavailability out of all of the alpha-tocopherol stereoisomers. Moreover, RRR-alpha-tocopherol acetate is a relatively stabilized form of vitamin E that is most commonly used as a food additive when needed. Alpha-tocopherol acetate is subsequently most commonly indicated for dietary supplementation in individuals who may demonstrate a genuine deficiency in vitamin E. Vitamin E itself is naturally found in various foods, added to others, or used in commercially available products as a dietary supplement. The recommended dietary allowances (RDAs) for vitamin E alpha-tocopherol are: males = 4 mg (6 IU) females = 4 mg (6 IU) in ages 0-6 months, males = 5 mg (7.5 IU) females = 5 mg (7.5 IU) in ages 7-12 months, males = 6 mg (9 IU) females = 6 mg (9 IU) in ages 1-3 years, males = 7 mg (10.4 IU) females = 7 mg (10.4 IU) in ages 4-8 years, males = 11 mg (16.4 IU) females = 11 mg (16.4 IU) in ages 9-13 years, males = 15 mg (22.4 IU) females = 15 mg (22.4 IU) pregnancy = 15 mg (22.4 IU) lactation = 19 mg (28.4 IU) in ages 14+ years. Most individuals obtain adequate vitamin E intake from their diets; genuine vitamin E deficiency is considered to be rare. Nevertheless, vitamin E is known to be a fat-soluble antioxidant that has the capability to neutralize endogenous free radicals. This biologic action of vitamin E consequently continues to generate ongoing interest and study in whether or not its antioxidant abilities may be used to help assist in preventing or treating a number of different conditions like cardiovascular disease, ocular conditions, diabetes, cancer and more. At the moment however, there exists a lack of formal data and evidence to support any such additional indications for vitamin E use.|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.
D-alpha-tocopheryl acetate is a natural form of vitamin E and it is stable in terms of shelf life. It is probably the best form for people actively trying to prevent heart disease. It is used in the dietary and clinical supplementations.

Air and Water Reactions:D-alpha-Tocopheryl acetate may be sensitive to prolonged exposure to light and air. . Insoluble in water.
Reactive Group:Esters, Sulfate Esters, Phosphate Esters, Thiophosphate Esters, and Borate Esters
Reactivity Profile:An ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Critical Temperature & Pressure:room temp
