Vitamin E DL-Alpha-Tocopheryl Acetate (CAS 7695-91-2) is the acetic acid ester of alpha-tocopherol, a clear yellow viscous liquid that is insoluble in water and soluble in organic solvents, and it is used as an antioxidant in cosmetics, in pharmaceuticals for wound healing and in supplements for immune support. It has a density of 0.96 g/cm³, boiling point 363°C, flash point 210°C, refractive index 1.495-1.497. Insoluble in water, soluble in organic solvents like acetone and ethanol, it is stable, less susceptible to oxidation than tocopherol, and produced by esterification of alpha-tocopherol with acetic acid.
