Tocopheryl acetate uses
1. Tocopherol acetate has significant functions of anti-oxidation, eliminating free radicals in the body, preventing cancer and enhancing immunity. It is an indispensable vitamin in human life activities. However, since the six-hydroxyl group on the vitamin E chroman ring is easily oxidized to form the corresponding quinone which no longer has the biological activity of vitamin E. Vitamin E esterification can prevent the oxidation of vitamin E, improve the stability of vitamin E products, solve the problem of poor water solubility and increase its surface activity.
2. Vitamin E acetate is a derivative of vitamin E. It has good stability and can be widely used as a vitamin E substitute for medicine, food and cosmetics. Vitamin E acetate is a white or yellowish powder or granule, or a viscous liquid that is slightly greenish yellow or yellow. It is almost odorless and its color becomes deeper in light. After vitamin E becomes vitamin E acetate, it has other special effects. For example, vitamin E acetate can be used to treat dryness of the oral mucosa, dryness and itching of the vagina, ulceration of the rectum, nose and eye mucosa, inflammation, glossitis, keratoconjunctivitis, keratitis, corneal pain, corneal ulcer, corneal epithelialization, envelope rhinitis, nasal vestibulitis, atrophic vaginitis, etc. It can also be used in cosmetics, food and feed.
Tocopheryl acetate in cosmetics
1. Tocopherol acetate is a widely recognized skin conditioning and moisturizer. It is also an antioxidant. This compound is used in most brands of skin creams and lotions to strengthen the skin’s defense against UV rays and even to alleviate wrinkles.
2. The acetate of tocopherol acetate slowly penetrates into the skin to prevent harmful UV rays. It promotes moisture by removing free radicals and preventing dry skin, which can result in shedding or killing of skin cells. This is especially important when the skin is exposed to sunburn, frostbite or other irritation.
