Description

Isobutyl Gallate is a synthetic ester of gallic acid, widely recognized for its potent antioxidant properties. This compound is crucial for inhibiting oxidative degradation, thereby extending the shelf life and stability of various formulations. It serves as a key additive for manufacturers in the food, cosmetic, pharmaceutical, and industrial sectors seeking reliable protection against rancidity and spoilage.

Application

• Food & Beverage Antioxidant: Used to prevent oxidation and rancidity in edible oils, fats, snacks, and processed foods.
• Cosmetic & Personal Care Stabilizer: Incorporated into creams, lotions, and makeup to protect active ingredients and prevent color/odor changes.
• Pharmaceutical Excipient: Acts as an antioxidant in drug formulations to enhance the stability of active pharmaceutical ingredients (APIs).
• Industrial Additive: Functions as a stabilizer in lubricants, fuels, plastics, and rubber to mitigate oxidative breakdown.
• Animal Feed Preservative: Added to feed to maintain nutritional quality and prevent fat spoilage.
