Properties Description: greenish yellow or light yellow viscous liquid, basically odorless, relative density 0.947 ~ 0.955. Insoluble in water, but soluble in ethanol, gasoline, ethyl ester and vegetable oil. Stable to heat, heating to 200℃ almost does not decompose; It is stable to oxygen in the air, but slow oxidation occurs, and the oxidation resistance of the finished product is weaker than that of the natural product. The light darkens gradually.

Uses: For the prevention of abortion caused by vitamin E deficiency, habitual abortion and threatened abortion, and also for the treatment of infertility and infant nutritional giant cell anemia. Vitamin E has strong reducibility, has the role of anti-oxidation in the process of human metabolism to prevent aging, and can maintain the normal function of reproductive organs. It can also be used as a nutritional booster. China's regulations can be used to strengthen sesame oil, salad oil, margarine and dairy products. Usage of 100 ~ 180mg/kg; The amount of consumption in fortified infant food is 40-70ug /kg, and the maximum amount of consumption in fortified tocopherol drinks is 20-40mg /L; The amount used in fortified milk drinks is 10 to 20ug/kg. Vitamin E is widely distributed in animal and vegetable oils, egg yolks, milk, fruits, lettuce leaves and other foods, wheat germ oil, corn oil, peanut oil, cottonseed oil is also rich in vitamin E.

Method: Natural vitamin E can be extracted from vegetable oils such as wheat germ oil, soybean oil, cottonseed oil and rice bran oil. Tocopherol can also be synthesized from 2,3,5 -- methyl hydroquinone and phytol, and obtained by acetylation and extraction.

Packing and storage: sealed and stored in a cool place. After opening, it should be replaced by inert gas and should not be placed in high temperature and direct sunlight for a long time.
