Overview
D-alpha Tocopheryl Acetate is a synthetic derivative of Vitamin E, commonly used for its antioxidant properties. It is more stable than its natural counterpart, making it ideal for industrial applications. The compound is widely utilized in pharmaceuticals, cosmetics, and food industries due to its ability to protect against oxidative damage. As a fat-soluble vitamin, D-alpha Tocopheryl Acetate is easily absorbed by the body, making it a popular ingredient in dietary supplements and skincare products. Its synthetic nature ensures consistent quality and efficacy, which is crucial for B2B applications.
Physical and Chemical Properties
D-alpha Tocopheryl Acetate is a pale yellow viscous liquid with a mild odor. It has a molecular weight of 472.75 g/mol and a density of 0.95 g/cm³. The compound melts at 25-28°C and decomposes at higher temperatures, making it unsuitable for high-heat applications. Its solubility in fats and organic solvents makes it versatile for formulations in cosmetics and pharmaceuticals. However, it is insoluble in water, which limits its use in aqueous systems. The compound is stable under normal storage conditions but should be protected from light and oxidizing agents to maintain its efficacy.
Main Applications
D-alpha Tocopheryl Acetate is primarily used in the pharmaceutical industry as an ingredient in Vitamin E supplements and topical treatments. Its antioxidant properties help protect cells from oxidative stress, making it valuable in anti-aging skincare products. In the food industry, it serves as a preservative to extend shelf life by preventing oxidation of fats and oils. Additionally, it is added to animal feed to improve nutritional value. The cosmetic industry leverages its stability and skin-conditioning benefits in lotions, creams, and sunscreens.
Safety and Storage
D-alpha Tocopheryl Acetate is generally recognized as safe (GRAS) by regulatory authorities. However, prolonged exposure to high concentrations may cause skin irritation. Proper handling includes wearing gloves and avoiding inhalation of vapors. Storage should be in a cool, dry place away from direct sunlight and oxidizing agents. The compound is stable under normal conditions but may degrade if exposed to extreme temperatures or humidity. Bulk procurement should ensure airtight containers to prevent contamination and maintain purity.
B2B Procurement Guide
When procuring D-alpha Tocopheryl Acetate, verify the CAS number (58-95-7) and purity levels, typically ranging from 96% to 99%. Compliance with industry standards such as USP (United States Pharmacopeia) or FCC (Food Chemicals Codex) is essential for quality assurance. Suppliers should provide certificates of analysis (CoA) and material safety data sheets (MSDS). Pricing varies based on quantity and purity, with bulk purchases often offering cost advantages. Consider sourcing from reputable manufacturers with a track record of consistent quality and regulatory compliance.
