Description

Ethyl Gallate is a high-purity ester derivative of gallic acid, valued for its potent antioxidant and preservative properties. This compound is essential for industries requiring stabilization against oxidative degradation and microbial growth. It is a critical ingredient for manufacturers in the pharmaceutical, food & beverage, and personal care sectors seeking reliable, high-quality raw materials.

Application

• Pharmaceutical Antioxidant: Used as an excipient in tablet and capsule formulations to enhance the stability of active pharmaceutical ingredients (APIs) susceptible to oxidation.
• Food & Beverage Preservative: Acts as a shelf-life extender in oils, fats, and processed foods by inhibiting rancidity and spoilage.
• Cosmetic & Personal Care Stabilizer: Incorporated into creams, lotions, and serums to prevent the oxidation of sensitive ingredients like vitamins and oils.
• Industrial Antioxidant: Serves as an additive in lubricants, polymers, and adhesives to prevent oxidative breakdown and extend product life.
• Research & Development: Utilized as a standard or reagent in biochemical and pharmacological research studying antioxidant mechanisms.
• Nutraceutical Ingredient: Found in dietary supplement formulations for its potential health-beneficial antioxidant properties.

Quality Control

Our Ethyl Gallate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR spectroscopy, to ensure it meets stringent specifications. Certificates of Analysis (COA) documenting all test results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere); prolonged exposure to air, light, or elevated temperatures should be avoided to maintain stability and purity.
