DL-Alpha Tocopherol High Purity | Hersoncare

1. Product Overview

DL-Alpha Tocopherol (chemical name: all-rac-ɑ-tocopherol) is a high-purity synthetic form of vitamin E, developed and supplied by Hersoncare—your trusted partner for Food Additives and Cosmetic Raw Materials. This product is produced through advanced chemical synthesis combined with precision purification technology, ensuring consistent quality and performance across every batch.

Visually, it presents as a clear, light yellow to amber viscous liquid with a stable molecular structure (Molecular Formula: C29H50O2; CAS No.: 10191-41-0). Its core advantage lies in strong antioxidant properties—effectively neutralizing free radicals to protect cell membranes and lipids from oxidative damage. Unlike ordinary vitamin E derivatives, our DL-Alpha Tocopherol boasts a minimum assay of 96%, making it ideal for applications requiring high potency and reliability.

As a versatile ingredient, it plays a critical role in Food & Nutrition, dietary supplements, infant nutrition, and cosmetics. It supports immune function, promotes cardiovascular health, and enhances skin barrier protection—while also extending the shelf life of oxidation-prone products as a natural-sounding preservative alternative.

3. Technical Specifications

Our DL-Alpha Tocopherol meets strict international standards (E307/JECFA/GB) to ensure safety and consistency. Below are the detailed technical parameters, verified through advanced testing methods (e.g., GC for assay, UV-Vis for specific absorption):

Appearance: Slightly yellow to amber, clear, viscous oily liquid (no sediment or turbidity)
Identification: Complies with E307 (EU), JECFA (FAO/WHO), and GB (China) standards
Chromaticity: ≤4.0 (APHA scale, ensuring consistent color across batches)
Refractive Index (20°C): 1.503～1.507 (indicates high molecular purity)
Specific Absorption (292nm): 72～76 (confirms structural integrity of tocopherol molecules)
Acidity: ≤1.0mL (0.1mol/L NaOH consumption per 10g sample; low acidity ensures compatibility with neutral/basic formulations)
Related Substances (Impurities):
- Impurity A (tocopheryl quinone): ≤0.5%
- Impurity B (beta-tocopherol): ≤1.5%
- Sum of Impurities C (gamma-tocopherol) and D (delta-tocopherol): ≤1.0%
- Any other single impurity: ≤0.25%
- Total impurities: ≤2.5% (well below industry average of 5%)
Assay (by Gas Chromatography, GC): 96.0%～102.0% (guarantees high potency for effective results)
Residue on Ignition: ≤0.1% (minimal inorganic impurities, suitable for food/cosmetic use)
Heavy Metals:
- Arsenic (As): ≤1ppm (meets strict food safety limits)
- Lead (Pb): ≤2mg/kg (complies with EU Regulation (EC) No 1881/2006)
Solubility: Soluble in oils (e.g., vegetable oil, mineral oil) and organic solvents (e.g., ethanol, acetone); insoluble in water (ideal for oil-based formulations)
Stability: Stable under cool, dry conditions (avoid direct sunlight and high temperatures above 60°C)

4. Product Features & Advantages

High Purity & Stability

With an assay of 96.0%～102.0% and total impurities ≤2.5%, our DL-Alpha Tocopherol ensures minimal interference in formulations. Its stable molecular structure resists oxidation during storage and processing, maintaining potency for longer than standard vitamin E products.

Powerful Antioxidant Activity

As a premium Antioxidants Raw Material, it efficiently scavenges free radicals to protect lipids, proteins, and cell membranes from oxidative damage. In food applications, it extends shelf life by 30%～50% for oil-based products (e.g., cooking oils, nuts).

Broad Formulation Compatibility

Soluble in all common oils and organic solvents, it integrates seamlessly into food, supplements, and cosmetics. It does not react with other ingredients (e.g., Vitamins & Minerals, emulsifiers) and maintains stability across pH ranges 4～8.

Global Regulatory Compliance

Meets standards of EU, US FDA, JECFA, and China GB. Free from allergens, GMOs, and harmful residues (e.g., heavy metals, pesticides), making it suitable for use in infant food and sensitive skin cosmetics.

Superior Cost-Effectiveness

Synthetic production ensures stable pricing and large-scale supply (monthly capacity: 500MT). High potency means lower dosage requirements—e.g., only 0.02%～0.1% addition is needed to preserve cooking oils, reducing overall formulation costs.

Sustainable Manufacturing

Our production process uses 30% less energy and 50% less water than traditional methods. Packaging materials are recyclable, and we offer a "take-back" program for empty drums to reduce environmental impact.
