Description

Octyl Gallate is a synthetic ester of gallic acid, widely recognized for its potent antioxidant properties. This compound is essential for preventing oxidative degradation and rancidity in a variety of industrial formulations. It is a critical additive for manufacturers in the food, cosmetic, and polymer industries seeking to extend product shelf life and maintain stability.

Application

• Food & Beverage Antioxidant: Used as a preservative (E311) in edible oils, fats, margarine, and snack foods to prevent rancidity and spoilage.
• Cosmetics & Personal Care: Acts as a stabilizer in creams, lotions, and lipsticks to protect ingredients from oxidation and extend product life.
• Polymer & Plastics Stabilizer: Inhibits thermal and oxidative degradation in synthetic rubbers, adhesives, and polyolefins during processing and storage.
• Pharmaceutical Excipient: Serves as an antioxidant in certain medicinal formulations and dietary supplements to maintain active ingredient potency.
• Industrial Greases & Lubricants: Enhances the oxidative stability of petroleum-based and synthetic lubricants under high-temperature conditions.
