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.
Tocopherol and tocopheryl acetate are used mainly as
antioxidants. Tocopheryl acetate, an ester of tocopherol
(vitamin E), can induce allergic contact dermatitis.
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.
Flash point data for D-alpha-Tocopheryl acetate are not available. D-alpha-Tocopheryl acetate is probably combustible.
