Product Description of Vitamin E CAS#59-02-9
Natural Vitamin E is a brown-red or transparent light yellow oily liquid with a mild and distinctive odor and taste. It is easily soluble in ethanol, acetone, ether, chloroform, and vegetable oils, while being almost insoluble in water.
Vitamin E has a high boiling point of 250°C and is heat-stable, although it may oxidize and turn dark red when exposed to air and light. It contains no calories and does not participate in human metabolism.
Natural Vitamin E is valued for its benefits in spot brightening, anti-aging, endocrine regulation, and cardiovascular support, including the prevention of high blood pressure and blood clots. Due to these properties, it is widely used in food, nutritional supplements, cosmetics, and related industries.

Product Applications of Vitamin E CAS#59-02-9
Vitamin E has been included as an active ingredient in certain over-the-counter (OTC) drug products for specific applications, including topical acne treatments and weight control products. However, based on the currently available evidence, there are still insufficient data to establish general recognition of its safety and effectiveness for these specific OTC uses.
In addition, tocopherols are generally recognized as safe when used in accordance with good manufacturing or feeding practices as:
Chemical preservatives in animal drugs, feeds, and related products
Nutrients and/or dietary supplements in animal drugs, feeds, and related products
Similarly, alpha-tocopherol acetate is also generally recognized as safe when used as a nutrient and/or dietary supplement in animal drugs, feeds, and related products, provided it complies with good manufacturing or feeding practices.
