Octyl gallate

Octyl gallate (CAS 1034-01-1), also designated E311, is a lipophilic antioxidant and preservative derived from gallic acid. It protects fats, oils, and oil-containing formulations from oxidative degradation. This additive is essential for extending shelf life and maintaining product quality across food, cosmetic, and industrial applications. In food manufacturing, it is used to stabilize edible fats and oils.

It is commonly found in fat-containing products such as margarines, baked goods, and snack foods to prevent rancidity. Personal care formulators incorporate it into lipstick, creams, and oil-based cosmetics. Oxidative stability directly affects product longevity and sensory performance in these beauty applications. Pharmaceutical manufacturers use it to protect lipid excipients and oil-based drug delivery systems.

This protection is vital for preventing degradation during storage. In plastics and polymer processing, it functions as a stabilizer to inhibit oxidative breakdown of polymer matrices during production. The product is supplied as a white to off-white crystalline powder. It is available in food-grade quality conforming to E311 specifications under EU food additive regulations for global compliance.

It is also offered in pharmaceutical-grade and technical-grade forms to meet diverse industry requirements. Standard packaging ranges from small laboratory quantities to bulk industrial volumes for procurement. These options suit different production scales and logistical needs. Our supply chain ensures consistent quality and availability for all manufacturing sectors requiring high-performance antioxidants.
