Vitamin E Acetate Usage and Synthesis.

Tocopheryl acetate is the product of esterification of tocopherol (vitamin E) and acetic acid. It is not an oestrogen, but a fat-soluble vitamin with antioxidant properties, stable performance, slightly yellow or yellow transparent viscous liquid, almost odourless, easy to oxidise when exposed to light, the colour becomes darker. Vitamin E contains several properties that promote many aspects of human health, and it is widely used in a variety of personal care and hygiene products. Tocopheryl acetate is both a skin conditioner and an antioxidant, and when used as a cosmetic ingredient, it has a protective effect such as preventing skin damage from the sun's ultraviolet rays. In addition, it can be taken in the form of vitamin supplements.

Uses and functions of Vitamin E Acetate.

Vitamin E in the metabolic process of the body to prevent the cell membrane and intracellular unsaturated fatty acids and other oxidants are oxidised, thereby protecting the integrity of the cell membrane and thus preventing the role of aging, can maintain the normal function of the reproductive organs.

Vitamin E has strong reducing properties and can be used as an antioxidant.

Vitamin E has strong reducing properties, in the body's metabolic process there are antioxidant and thus prevent aging effect, can maintain the normal function of reproductive organs.

Generally, DL-vitamin E can be used as a nutritional fortifier, which can be used to fortify sesame oil, salad oil, margarine and dairy products with the dosage of 100～180mg/kg; in fortified baby food with the dosage of 40～70μg/kg; in fortified tocopherol drinks with the maximum dosage of 20～40mg/Ll; in fortified milk drinks with the dosage of 10～20μg/kg; or D-α-vitamin E can be used as an antioxidant, which has strong reducing effect in human metabolism and thus can prevent aging. kg.

It can also be fortified with D-α-tocopherol, D-α-tocopherol acetate or DL-α-tocopherol, and the dosage must be converted. Natural vitamin E concentrate can be used as an antioxidant.

Characteristic of Vitamin E Acetate.

Tocopheryl acetate is slightly yellow or yellow transparent viscous liquid, easily soluble in chloroform, ether, acetone and vegetable oil, soluble in alcohol, insoluble in water. It has good heat resistance and can be oxidised and darkened when exposed to light.

Product Method of Bulk Vitamin E Acetate.

Preparation of Natural Vitamin E Extraction Method Extraction from vegetable oils using low carbon alcohols of C1 to C4 or alcohol-ketone mixtures containing (5% to 15%) C3 to C5 low carbon ketones as the extractant. .

Such as in 100g of crude palm oil add 50mL of methanol, shaking at 45 ℃ extraction, at -10 ~ -20 ℃ to take the methanol phase frozen overnight, filtration to remove the precipitation of sterols and fatty acids crystals, the mother liquor distillation to remove the methanol to get Vitamin E concentrate, content of 11%.

Esterification method to the deodorisation of fats and oils in the deodorisation process distillate as raw material, with polyol esterification of fatty acids, and steam distillation to remove the ester and get the concentrate.

Such as in 1000g of soybean oil deodorised distillate (acid value 68.8, saponification value of 133, iodine value 152) in the addition of the equivalent acid value of 1.1 times (41.4g) of glycerol, reflux esterification with xylene (240 ° C) to the acid value down to 0.5 until the removal of solvents and then distil the esterified material with water vapour distillation (at 400Pa), the distillation of the process of the free acid and then esterify with glycerol, and finally distilled! The concentrate was obtained with a content of 56.3% and a yield of 64.8%. It can also be used in saponification method, enzyme method and other methods.
