Description

2-tert-Butyl-4-Hydroxyanisole is a synthetic phenolic antioxidant widely used to prevent oxidative degradation in various materials. This compound is valued for its effectiveness in stabilizing products against deterioration caused by exposure to oxygen and heat. It is a critical additive for manufacturers in the polymer, food, and cosmetic industries seeking to extend product shelf life and maintain quality.

Application

• Primary antioxidant in polyolefins (e.g., polyethylene, polypropylene) and other polymers to prevent thermal oxidation during processing and service life.
• Food-grade antioxidant (BHA - Butylated Hydroxyanisole) for preserving fats, oils, and fat-containing foods from rancidity.
• Stabilizer in cosmetics and personal care products, such as lipsticks and moisturizers, to protect organic ingredients.
• Additive in petroleum-based products including lubricants, greases, and fuels to enhance oxidative stability.
• Antioxidant in adhesives, sealants, and rubber formulations to improve durability.
• Used in animal feed as a preservative to maintain nutritional quality.
