Chemical Properties off-white crystalline solid
Uses Used in prevention and treatment of vitamin E deficiencies.
General Description Odorless off-white crystals. Darkens at 401° F.
Air & Water Reactions D-alpha-Tocopheryl acetate may be sensitive to prolonged exposure to light and air. . Insoluble in water.
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.
Fire Hazard Flash point data for D-alpha-Tocopheryl acetate are not available. D-alpha-Tocopheryl acetate is probably combustible.
Contact allergens Tocopherol and tocopheryl acetate are used mainly as antioxidants. Tocopheryl acetate, an ester of tocopherol (vitamin E), can induce allergic contact dermatitis.
Safety Profile When heated to decomposition it emits acrid smoke and irritating fumes.
