Description

Dodecyl Gallate is a synthetic antioxidant belonging to the gallate ester family. This compound is valued for its ability to inhibit oxidation and extend the shelf life of various materials by scavenging free radicals. It is primarily utilized by manufacturers in the food, cosmetics, and industrial polymer sectors seeking effective stabilization solutions. Its lipophilic nature makes it particularly suitable for oil-based and fatty systems.

Application

• Food Antioxidant: Used to prevent rancidity in edible oils, fats, margarine, and snack foods.
• Cosmetics & Personal Care: Acts as a stabilizer in creams, lipsticks, and other formulations containing oils to prevent spoilage.
• Polymer & Plastics Industry: Serves as an antioxidant additive in polyolefins, rubbers, and adhesives to prevent thermal and oxidative degradation during processing and use.
• Pharmaceutical Excipient: Employed as an antioxidant in certain ointment and cream bases to maintain API stability.
• Animal Feed Additive: Helps preserve the nutritional quality and freshness of fat-containing feed components.
• Industrial Lubricants & Greases: Inhibits oxidation, thereby extending the functional life of lubricating oils and greases.
