Description

3-tert-Butyl-4-Hydroxyanisole is a synthetic phenolic antioxidant widely used to inhibit oxidative degradation in various materials. This compound is valued for its effectiveness in stabilizing products against rancidity, color change, and polymer chain scission, thereby extending shelf life and maintaining performance. It is a critical additive for manufacturers in the food, polymer, cosmetic, and industrial lubricant sectors seeking reliable oxidation control.

Application

• Food & Beverage Antioxidant: Used to prevent rancidity and preserve flavor in oils, fats, baked goods, and snack foods.
• Polymer & Plastic Stabilizer: Inhibits thermal and oxidative degradation in polyolefins (e.g., polyethylene, polypropylene), rubbers, and adhesives.
• Cosmetic & Personal Care Preservative: Protects oils, waxes, and emulsions in creams, lotions, and lipsticks from oxidation.
• Industrial Lubricant & Grease Additive: Extends the service life of lubricating oils and greases by preventing oxidative thickening and acid formation.
• Petrochemical Product Stabilizer: Added to gasoline, jet fuels, and transformer oils to improve oxidative stability.
• Animal Feed Preservative: Helps maintain the nutritional quality and prevent spoilage of fat-containing feed ingredients.
