CAS No: 59-02-9
EINECS No:224-403-8
Molecular Formula:C29H50O2
Resource: Soy Bean oil
Vitamin E oil-mixed tocopherols (Tocopherol) is derived from soybean oil, as nature's fat-soluble antioxidant constitutes: Alpha-tocopherol, Beta-tocopherol, Gamma-tocopherol, Delta-tocopherol. Beta-tocopherol exists in concentrations too low to have any practical significance, free of solvent residue and metal ion. Gamma and Delta-tocopherols are known primarily for their antioxidant properties. Being used as antioxidant, their physiological activities are: Delta > Beta > Gamma > Alpha. Nowadays, Natural Vitamin E is divided into Mixed Tocopherol (Low alpha-tocopherol) and Tocopherol (High alpha-tocopherol).
Characteristics:

• Soluble in ethanol, acetones, diethyl ether, chloroform and vegetable oils & fats, Insoluble in water.
• No calorie, not involved in metabolism in human body .
Molecular formula:
Alpha-tocopherol: R1=R2=CH3,
Beta-tocopherol: R1=H, R2=CH3
Gamma-tocopherol: R1=CH3, R2=H
Delta-tocopherol: R1=R2=H,
