Natural Vitamin E
Vitamin E is a group of fat soluble compounds that include four tocopherols and four tocotrienols. Vitamin E cannot be synthesized by the body itself but need to be obtained from the diet or supplements. The main four components of natural vitamin E, including naturally-occurring d-alpha, d-beta, d-gamma and d-delta tocopherols. Compared to the synthetic form (dl-alpha-tocopherol), the natural form of vitamin E, d-alpha-tocopherol, is better retained by the body. The bioavailability (availability for use by the body) is 2:1 for natural-source Vitamin E over synthetic Vitamin E.
Natural Vitamin E can help in protecting the skin from environmental damage. It acts as both a humectant and emollient and provides excellent moisturisation properties which help reduce the appearance of wrinkles. It can also assist in hair growth and maintaining a healthy scalp.YR Chemspec supply Natural Vitamin E including Mixed tocopherols Oil,D-alpha tocopherol oil and D-alpha tocopherol acetates. All our products are in manufacturer-friendly forms for capsules, tablets and other applications.
1. Mixed Tocppherols Oil
Mixed Tocopherols Oil are a clear, viscous, brownish red oil with a mild vegetable oil-like odour. Mixed Tocopherols contain naturally occuring mixtures of alpha, beta, gamma and delta tocopherols. It is a widely used ingredient in foods, dietary supplements, animal feeds and industrial applications to help protect finished products from the damaging effects of oxidation.

Application:
Mixed Tocopherols Oil is used a main additive in all kinds of VE functional food like bread, snacks products, aquatic refined products, beverage (dairy products), cookies class, condiments, Fried food, health food products and cosmetics.
2.D-alpha tocopherol Oil
D-alpha Tocopherol is a monomer of the natural vitamin E derived from soybean oil distillate, and then diluted with edible oil to various contents. It is odorless, yellow to brownish red, clear oily liquid. Usually, it is produced by methylation and hydrogenation from mixed tocopherols. It can be used as antioxidant and nutrient in foods, cosmetics and personal care products, also can be used in feed and pet food.

Applications:
• D-α tocopherol is used for habitual abortion, threatened abortion, infertility and menopausal disorders; Progressive muscular dystrophy, premature hemolytic anemia, leg spasm, intermittent claudication, etc. Can also be used for coronary heart disease, hyperlipidemia, atherosclerosis and so on.
• D-α tocopherol can also be used to delay aging, as well as deficiency caused by leachate and inflammatory skin diseases, skin keratinization, hair loss, and abnormal fat absorption, but its efficacy is uncertain.
3.D-alpha tocopherol acetates
D-alpha Tocopheryl Acetate is colorless to yellow, nearly odorless, clear oily liquid. Usually it is produced by esterification of acetic acid and natural d-alpha tocopherol, and then diluted with edible oil to various contents. It can be used as antioxidant in foods, cosmetics and personal care products, also can be used in feed and pet food.
