Description

Butyl Gallate CAS NO 1083-41-6 is a synthetic phenolic antioxidant belonging to the gallate ester family. This compound is valued for its ability to inhibit oxidation and extend the shelf life of a wide range of products by scavenging free radicals. It is a critical additive for manufacturers in the food, cosmetic, and industrial sectors seeking to prevent rancidity, discoloration, and degradation of their formulations.

Application

• Food & Beverage Antioxidant: Used to stabilize edible oils, fats, margarine, snacks, and baked goods to prevent rancidity and preserve flavor.
• Cosmetic & Personal Care Stabilizer: Incorporated into creams, lotions, lipsticks, and other formulations to protect active ingredients and base oils from oxidative spoilage.
• Pharmaceutical Excipient: Serves as an antioxidant in certain drug formulations and vitamin preparations to maintain potency and stability.
• Industrial Additive: Functions as a stabilizer in lubricating greases, transformer oils, adhesives, and synthetic polymers to inhibit oxidative degradation.
• Animal Feed Preservative: Added to feed and premixes to protect nutritional value by preventing fat and vitamin oxidation.
