Product Description
Natural Vitamin E, commonly identified as D-α-tocopherol, is typically a clear, pale yellow to amber or brownish-red oily liquid with a characteristic mild odor. It is soluble in ethanol, acetone, ether, chloroform, and vegetable oils, but practically insoluble in water.
As a fat-soluble antioxidant, Vitamin E helps protect lipids from oxidation. However, it may gradually oxidize and undergo color changes when exposed to air, light, or unsuitable storage conditions. Proper packaging and storage are therefore important for maintaining product quality.
Natural Vitamin E is widely used in dietary supplements, food applications where permitted, and cosmetic formulations. In skin-care products, it is valued for its antioxidant and skin-conditioning properties. In nutritional formulations, it serves as a source of Vitamin E, an essential nutrient that supports normal physiological functions. Its specific properties and applications depend on the product grade, purity, formulation, and intended use.
