Description

Tocopherol CAS NO 1604-73-5 is a vital form of Vitamin E, a group of fat-soluble compounds renowned for their potent antioxidant properties. It is essential for protecting oils, fats, and sensitive ingredients from oxidative degradation, thereby extending shelf life and maintaining product integrity. This high-purity ingredient is critical for manufacturers in the nutraceutical, food & beverage, cosmetic, and pharmaceutical industries seeking natural antioxidant solutions.

Application

• Nutraceutical & Dietary Supplements: A key active ingredient in Vitamin E capsules, multivitamin formulations, and antioxidant blends for human and animal nutrition.
• Food & Beverage Fortification and Preservation: Used as a natural antioxidant (E306) to prevent rancidity in edible oils, fats, margarine, and processed foods, and to fortify products with Vitamin E.
• Cosmetics & Personal Care: Incorporated into anti-aging creams, lotions, serums, and sunscreens for its skin-conditioning and protective benefits against free radicals.
• Pharmaceuticals: Serves as an excipient and active pharmaceutical ingredient (API) in various medicinal formulations, including topical ointments and oral medications.
• Animal Feed Additive: Added to feed premixes to enhance the nutritional value, support animal health, and improve the stability of feed fats.
• Industrial Antioxidant: Applied in specialty lubricants, polymers, and bio-based materials to inhibit oxidative breakdown and prolong functional life.

Quality Control

Our Tocopherol is produced and tested under strict quality management systems to ensure it meets the highest standards of purity and consistency. We offer grades compliant with major pharmacopoeias, including USP, EP, and FCC specifications for pharmaceutical, nutraceutical, and food applications. Each batch is supported by a comprehensive Certificate of Analysis (COA), detailing key parameters such as assay, identity, and impurity profiles. Certifications for GMP, ISO, and REACH compliance are available to support your regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at temperatures between 15-25°C. This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve potency and prevent degradation. Keep away from strong oxidizing agents.
