Product Introduction
D alpha tocopheryl acetate is extracted and purified into various vitamin E after the chemical processes of pretreatment, adsorbption seperation, hydroxymethyl hydrogenation transformation and molecular sulfide.
Alpha tocopherol acetate is the primary form of vitamin E that is preferentially used by the human body to meet appropriate dietary requirements. In particular, the tocopheryl acetate USP grade (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,alpha tocopherol acetate is a relatively stabilized form of vitamin E that is most commonly used as a food additive when needed 6.
Application
In nature, d alpha tocopheryl acetate comes in the form of tocopheryl or tocotrienol. Both tocopheryl and tocotrienol have four forms, known as alpha, beta, gamma, and delta. Tocopheryl actate USP grade is the most active form of vitamin E in humans.
D alpha tocopheryl acetate is a clear, pale yellow, viscous oil having a slight characteristic vegetable oil aroma and a mild
taste. This stable form does not degrade if exposed to air or light, but is affected by alkali.Apha tocopheryl acetate is
derived from edible vegetable oils. Research indicates that the human body prefers the natural source Vitamin E, such as Vitamin E , over the synthetic forms.alpha tocopherol has twice the activity of synthetic forms, which means that natural Vitamin E is 100% more effective. Tocopheryl acetate USP grade is an essential nutrient and dietary supplement widely used in softgel capsules and liquid preparations. Due to its stability, it is also used in food fortification and cosmetics.
