Uses α-Tocopherol acetate is the most bioactive of the naturally occurring forms of Vitamin E. Richest sources are green vegetables, grains, and oils, particularly palm, safflower and sunflower oils. Uses (+)-α-Tocopherol acetate has been used: as a component of growth medium for retinal cell lines as an external standard in high performance liquid chromatography (HPLC) to study its composition in leafy vegetables in the preparation of trans-resveratrol-encapsulated lipid nanocarriers (R-nano) General Description Odorless off-white crystals. Darkens at 401° F. Air & Water Reactions D-alpha-Tocopheryl acetate may be sensitive to prolonged exposure to light and air. . Insoluble in water. Reactivity Profile An ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Fire Hazard Flash point data for D-alpha-Tocopheryl acetate are not available. D-alpha-Tocopheryl acetate is probably combustible. Biochem/physiol Actions α-Tocopherol acetate or vitamin E-acetate has antioxidant properties and reduces lipid peroxidation. However, vitamin E acetate on pyrolysis leads to the generation of carcinogens like alkenes and benzenes. Contact allergens Tocopherol and tocopheryl acetate are used mainly as antioxidants. Tocopheryl acetate, an ester of tocopherol (vitamin E), can induce allergic contact dermatitis. Safety Profile When heated to decomposition it emits acrid smoke and irritating fumes.   D-alpha-Tocopheryl acetate Preparation Products And Raw materials Raw materials Sodium acetate trihydrate-->Trimethylhydroquinone-->PHYTANTRIOL

Leader Biochemical Group is a large leader incorporated industry manufacturers and suppliers of advanced refined raw materials From the year of 1996 when our factory was put into production to year of 2020, our group has successively invested in more than 52 factories with shares and subordinates.We focus on manufacture Pharm & chemicals, functional active ingredients, nutritional Ingredients, health care products, cosmetics, pharmaceutical and refined feed, oil, natural plant ingredients industries to provide top quality of GMP standards products.All the invested factories' product lines cover API and intermediates, vitamins, amino acids, plant extracts, daily chemical products, cosmetics raw materials, nutrition and health care products, food additives, feed additives, essential oil products, fine chemical products and agricultural chemical raw materials And flavors and fragrances. Especially in the field of vitamins, amino acids, pharmaceutical raw materials and cosmetic raw materials, we have more than 20 years of production and sales experience. All products meet the requirements of high international export standards and have been recognized by customers all over the world. Our manufacture basement & R&D center located in National Aerospace Economic & Technical Development Zone Xi`an Shaanxi China. Now not only relying on self-cultivation and development as well as maintains good cooperative relations with many famous research institutes and universities in China. Now, we have closely cooperation with Shanghai Institute of Organic Chemistry of Chinese Academy of Science, Beijing Institute of Material Medical of Chinese Academy of Medical Science, China Pharmaceutical University, Zhejiang University. Closely cooperation with them not only integrating Science and technology resources, but also increasing the R&D speed and improving our R&D power. Offering Powerful Tech supporting Platform for group development. Keep serve the manufacture and the market as the R&D central task, focus on the technical research.  Now there are 3 technology R & D platforms including biological extract, microorganism fermentation and chemical synthesis, and can independently research and develop kinds of difficult APIs and pharmaceutical intermediates. With the strong support of China State Institute of Pharmaceutical Industry (hereinafter short for CSIPI), earlier known as Shanghai Institute of Pharmaceutical Industry (SIPI), we have unique advantages in the R & D and industrialization of high-grade, precision and advanced products.  Now our Group technical force is abundant, existing staff more that 1000 people, senior professional and technical staff accounted for more than 50% of the total number of employees, including 15 PhD research and development personnel, 5 master′ S degree in technical and management personnel 9 people. We have advanced equipment like fermentation equipment and technology also extraction, isolation, purification, synthesis with rich production experience and strict quality control system, According to the GMP required, quickly transforming the R&D results to industrial production in time, it is our advantages and our products are exported to North and South America, Europe, Middle East, Africa, and other five continents and scale the forefront in the nation, won good international reputation.  We believe only good quality can bring good cooperation, quality is our key spirit during our production, we are warmly welcome clients and partner from all over the world contact us for everlasting cooperation, Leader will be your strong, sincere and reliable partner in China.
