Description

Isopropylgallate is a synthetic phenolic antioxidant widely recognized for its efficacy in preventing oxidative degradation. This compound is crucial for extending the shelf life and maintaining the stability of various sensitive materials. It is primarily sought after by manufacturers in the food, cosmetic, pharmaceutical, and industrial polymer sectors for its protective properties.

Application

• Food Antioxidant: Used to prevent rancidity in oils, fats, and fat-containing foods.
• Cosmetic & Personal Care Stabilizer: Protects creams, lotions, and other formulations from oxidation, preserving color and fragrance.
• Pharmaceutical Excipient: Serves as an antioxidant in topical ointments, creams, and certain drug formulations to enhance stability.
• Polymer & Plastic Additive: Inhibits thermal and oxidative degradation in rubbers, adhesives, and synthetic polymers during processing and service life.
• Industrial Grease & Lubricant Stabilizer: Extends the functional life of lubricating oils and greases by preventing oxidative thickening.
• Animal Feed Preservative: Helps maintain the nutritional quality and prevent spoilage of fat components in feed.
