D-Alpha-Tocopheryl Acetate (D-α-Tocopheryl Acetate) is a fat-soluble vitamin E derivative with potent antioxidant properties, widely used in food, pharmaceuticals, cosmetics, and animal feed. Below is a concise overview:

Chemical Information

Chemical Name: D-α-Tocopheryl Acetate (Natural Vitamin E)
CAS Number: 58-95-7
Molecular Formula: C₃₁H₅₂O₃
Molecular Weight: 472.74–472.75 g/mol
Appearance: Reddish-brown to red viscous oily liquid or semi-solid at room temperature, with a melting point of ~25–28°C and boiling point of 224°C (0.3 mmHg).

Physical & Chemical Properties

Solubility: Insoluble in water (<0.1 g/100 mL at 17°C), soluble in ethanol, ether, and organic solvents.
Density: 0.953 g/cm³ (25°C).
Refractive Index: 1.494–1.498.
Stability: Sensitive to light and prone to oxidation; requires storage in dark, cool conditions.

Key Applications

Food Industry

Antioxidant: Extends shelf life of oils, margarine, and processed foods by preventing lipid oxidation.
Nutritional Supplement: Fortifies foods to combat vitamin E deficiency.

Pharmaceuticals

Therapeutic Uses: Treats cardiovascular diseases, fatty liver, hypercholesterolemia, infertility, and menopausal symptoms.
Cellular Health: Supports membrane stability and reproductive function.

Cosmetics

Anti-Aging: Reduces UV damage, improves skin elasticity, and delays aging.
Skin Repair: Enhances barrier function and wound healing.

Animal Feed

Health Benefits: Boosts livestock fertility, prevents muscular dystrophy, and supports immune function.

Production Methods

Natural Extraction:

Extracts from plant oil deodorizer distillates (e.g., soybean, palm oil).
Purified via methanol/glycerol extraction or steam distillation.

Synthesis:

Condensation of phytol with trimethylhydroquinone.
Acetylation with acetic anhydride under zinc catalysis.
Steps:

Safety & Handling

Storage: Keep sealed, away from light and oxidizing agents.
Handling: Use gloves and goggles to avoid skin contact or inhalation.
Toxicity: Non-toxic at recommended doses, but excessive intake may cause diarrhea or metabolic imbalances.

Distinct Features

Natural vs. Synthetic: D-α-Tocopheryl Acetate (natural) has 3x higher bioactivity than the synthetic DL-form.
Esterified vs. Free: The acetate ester form is more stable and acts as a prodrug, releasing free tocopherol post-ingestion for sustained antioxidant activity.

Summary: D-Alpha-Tocopheryl Acetate is a vital natural antioxidant with superior bioactivity and stability. Its applications in nutrition, healthcare, and cosmetics highlight its irreplaceable role in protecting cells from oxidative damage and supporting overall health.
