Products Description
Natural Vitamin E is a brownish-red or transparent light yellow oily liquid with a mild characteristic odor and taste. It is readily soluble in ethanol, acetone, ether, chloroform, and vegetable oils, while it is almost insoluble in water. It has a high boiling point of approximately 250°C and demonstrates good thermal stability.
When exposed to air and light, Natural Vitamin E may undergo oxidation and gradually change to a dark red color. It contains no calories and does not participate directly in human metabolism. Due to its functions in skin brightening, reducing pigmentation, preventing skin aging, regulating endocrine balance, and supporting cardiovascular health, Natural Vitamin E is widely used in food products, nutritional supplements, cosmetics, and other applications.
