Are you going to wholesale vitamin e 98% acetate oil from a professional vitamin e 98% acetate oil producer and supplier? it is one of the well-known vitamin e 98% acetate oil manufacturers in China, welcome to contact our factory.
Vitamin E 98% is a high-purity, oil-soluble form of vitamin E, specifically all-rac-α-tocopheryl acetate. As a key synthetic vitamin e, it is one of the most widely used and cost-effective forms of vitamin E in the global dietary supplement, food fortification, and animal feed industries. This product is a clear, pale yellow to amber, viscous oil, known for its excellent stability and compatibility with a wide range of formulations.
HSF's all rac α tocopheryl acetate is produced through a synthetic process that ensures a consistent, high-purity product with a minimum assay of 98%. The acetate esterification of the tocopherol molecule provides superior oxidative stability compared to non-esterified tocopherols, making it the preferred form for long-term storage and challenging manufacturing conditions. This vitamin e acetate 98 grade is a versatile ingredient, ideal for softgel capsules, oil-based drops, and as a raw material for further processing into powders or other derivatives.

Technical Advantages
HSF's Vitamin E 98% is a high-quality all rac α tocopheryl acetate produced through a well-controlled synthetic process.
Synthesis and Purification:
The production of this synthetic vitamin e involves several critical steps to achieve its high purity and stability.
Chemical Synthesis: The process starts with the synthesis of the tocopherol ring structure, followed by the addition of the saturated side chain. The resulting product is a mixture of eight stereoisomers (all-rac), which mimics the composition of natural vitamin E but at a significantly lower cost.
Esterification: The free tocopherol is then esterified with acetic anhydride to form the acetate ester. This crucial step dramatically increases the molecule's resistance to oxidation, enhancing its shelf life and stability in finished products.
Molecular Distillation: A high-vacuum distillation step purifies the final product, removing impurities and ensuring it meets the stringent specifications for high-purity vitamin e acetate 98.
Functions
Vitamin E is a fat-soluble, chain-breaking antioxidant that plays a crucial role in protecting cells from oxidative stress by scavenging free radicals. This synthetic vitamin e helps to:
Support Cellular Health: Neutralizes free radicals, protecting cell membranes and other vital cellular components from oxidative damage.
Maintain Healthy Skin: Supports skin health and helps protect against the visible effects of aging caused by environmental factors.
Support Immune Function: Contributes to the normal function of the immune system.
Protect Lipids from Oxidation: Prevents the oxidation of polyunsaturated fatty acids and LDL particles, supporting cardiovascular health.
Applications
This vitamin e acetate 98 is a versatile and widely used ingredient across multiple industries:
Dietary Supplements:
