Description

Octadecyl Gallate is a synthetic ester of gallic acid, widely utilized as a highly effective antioxidant and stabilizer. Its primary value lies in its ability to inhibit oxidative degradation, thereby extending the shelf life and maintaining the integrity of various formulations. This compound is essential for manufacturers in the polymer, food, and cosmetic industries seeking reliable protection against rancidity and material breakdown.

Application

• Polymer & Plastics Stabilizer: Acts as an antioxidant in polyolefins (e.g., polyethylene, polypropylene) to prevent thermal and oxidative degradation during processing and service life.
• Food Additive (Antioxidant): Used in fats, oils, and fatty food products to delay the onset of rancidity and preserve flavor and nutritional quality.
• Cosmetic & Personal Care: Incorporated into creams, lotions, and makeup formulations to stabilize oils and butters against oxidation.
• Rubber Industry: Serves as an antioxidant in rubber compounds to protect against aging and ozone cracking.
• Adhesives & Sealants: Enhances the stability of adhesive formulations based on organic polymers.
• Industrial Lubricants & Greases: Prevents oxidation and sludge formation in lubricating oils and greases.
