Dietary Supplements: Acts as a key antioxidant to replenish vitamin E, supporting cardiovascular health and immune function.
Cosmetics/Personal Care: Applied in skin care (creams, serums, lotions) and hair care products for moisturization, free radical scavenging, skin barrier repair, and hair quality improvement.
Food Industry: Serves as a natural antioxidant and nutrient fortifier in edible oils, nuts, baked goods, and dairy products to extend shelf life and enhance nutritional value.
Our Advantages
Premium Purity & Natural Origin: Derived from high-quality vegetable oils, refined through advanced processes with D-α-tocopherol acetate content of 96%-99%, exceeding industry standards.
Optimal Biological Activity: D-α-tocopherol is the only natural stereoisomer of alpha-tocopherol with the highest biological activity (100%) among all vitamin E isomers.
Superior Stability: The unique acetylation process protects the phenolic hydroxyl group, ensuring stable antioxidant performance and a 24-month shelf life.
Innovative Technology Leadership: Possesses three core patented technologies: oil esterification & molecular distillation, high-efficiency separation, and oil microencapsulation, ensuring superior product quality.
Low-Temperature Concentration: Exclusive low-temperature concentration technology preserves maximum biological activity of natural functional components, avoiding thermal degradation.
Green & Safe Production: No chemical solvent residue, meeting international green safety standards, and holding multiple international certifications including ISO9001, ISO22000 ect.
Q1:What is the core difference between D-alpha tocopherol acetate and other vitamin E forms (e.g., DL-type)?
A2: The key difference lies in origin and bioactivity: D-alpha type is naturally extracted (from vegetable oil), with 100% bioactivity and high human absorption rate; DL-type is chemically synthesized (racemate) with only ~50% bioactivity, and the natural type aligns better with healthy consumption trends.
Q2: What is the recommended addition ratio and usage precautions?
A2: Recommended addition ratio: 0.1%-1% for health supplements, 0.5%-5% for cosmetics, 0.01%-0.1% for food (adjustable per specific needs); Precautions:
Avoid mixing with strong oxidants, store sealed at room temperature, keep away from high temperature and direct sunlight, and use as soon as possible after opening.
Q3: What are the product's purity standards and international certifications?
A3: Complying with USP, EP, FCC international standards;
Certifications: ISO9001, ISO22000 quality system certifications, NonGMO, Kosher, Halal certifications, no solvent residues, safe and compliant.
