Description

2-(3,4-Dihydro-6-Hydroxy-2,5,7,8-Tetramethyl-2H-1-Benzopyran-2-Yl)Ethyl Stearate is a synthetic lipophilic derivative of the natural antioxidant tocopherol, designed for enhanced stability and compatibility in lipid-based systems. This compound matters because it combines the potent free radical scavenging activity of a chromanol head with the solubility and carrier properties of a long-chain fatty acid ester. It is primarily needed by manufacturers in the cosmetics, nutraceutical, and polymer industries seeking to incorporate a non-irritating, oil-soluble antioxidant into their formulations to prevent rancidity and oxidative degradation.

Application

  • Cosmetic & Personal Care Formulations: Acts as a primary or synergistic antioxidant in creams, lotions, sunscreens, lipsticks, and hair oils to protect active ingredients and base oils from oxidation, extending product shelf life.
  • Nutraceutical & Dietary Supplements: Used in softgel capsules and oil-based supplement blends as a stabilizer to prevent the oxidation of sensitive oils like fish oil, flaxseed oil, and vitamin formulations.
  • Food-Grade Additives (where compliant): Functions as an antioxidant in food packaging materials and can be used in fat-based food products to inhibit lipid peroxidation.
  • Polymer & Plastic Stabilization: Incorporated into polyolefins (e.g., polyethylene, polypropylene) and other polymers as a processing and long-term thermal stabilizer to prevent chain scission and discoloration.
  • Industrial Lubricants & Greases: Added to synthetic and mineral-based lubricants to enhance oxidative stability, reduce sludge formation, and prolong service intervals under high-temperature conditions.
  • Animal Feed Additives: Protects fats and fat-soluble vitamins in premixes and finished feed from oxidative spoilage, ensuring nutritional value.

Quality Control

Our 2-(3,4-Dihydro-6-Hydroxy-2,5,7,8-Tetramethyl-2H-1-Benzopyran-2-Yl)Ethyl Stearate is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) that detail specifications such as assay, impurity profile, and physical constants. Our quality commitment aligns with cGMP principles for pharmaceutical and nutraceutical excipient production, and we can support compliance documentation for REACH, FDA, and other regulatory frameworks as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider keeping under an inert atmosphere (nitrogen or argon) to maintain maximum potency. Keep away from strong oxidizing agents and heat sources.
