Description

δ-Tocopherol Acetate is a specific, acetylated form of Vitamin E, known for its enhanced stability compared to its free alcohol counterpart. This compound is valued for its potent antioxidant properties, which are crucial for protecting sensitive ingredients from oxidative degradation. It is a key ingredient sought by manufacturers in the pharmaceutical, nutraceutical, and premium cosmetic industries for formulating stable and effective products.

Application

• Pharmaceutical Formulations: Used as an antioxidant and stabilizer in soft gelatin capsules, injectables, and topical ointments.
• Dietary Supplements & Nutraceuticals: A primary source of Vitamin E activity in multivitamin complexes, standalone capsules, and functional food fortification.
• Cosmetics & Personal Care: Incorporated into anti-aging serums, creams, and sunscreens for its skin-conditioning and protective benefits against environmental stressors.
• Animal Nutrition (Premixes): Added to feed for livestock and pets to ensure adequate Vitamin E levels, supporting immune function and product quality.
• Food Preservation: Acts as a natural antioxidant (E307) in oils, fats, and processed foods to extend shelf life.
• Biochemical Research: Serves as a standard or reagent in studies related to lipid peroxidation, oxidative stress, and nutrient metabolism.
