What are the uses of 2,6-di-tert-butyl-p-cresol?

2,6-Di-tert-butyl-p-cresol (BHT) is a common antioxidant with a wide range of uses in many fields, mainly including the following aspects:

1. Food field: As a food additive, BHT can prevent the oxidation and rancidity of oils, fats and other ingredients in food, extend the shelf life of food, and maintain the flavor and quality of food. It is often used in foods such as oils, fried foods, biscuits, and instant noodles. For example, adding an appropriate amount of BHT to vegetable oil can effectively inhibit the oxidation of oils and prevent the production of rancid smell, thereby extending the shelf life of edible oils.

2. Cosmetics field: In cosmetics, BHT can prevent the oxidation and deterioration of ingredients such as oils and spices, and maintain the stability and effectiveness of cosmetics. BHT is often added to products such as creams, lotions, and lipsticks to prevent the oxidation of oil components and avoid discoloration and taste changes in products.

3. Rubber and plastic industry: BHT is a commonly used antioxidant in rubber and plastic processing. It can inhibit the aging of rubber and plastics caused by oxidation, heat, light and other factors during processing and use, and improve the service life of rubber and plastic products. For example, adding BHT during the processing of natural rubber and synthetic rubber can effectively slow down the aging of rubber and maintain its elasticity and mechanical properties.

4. Lubricating oil and fuel oil field: In lubricating oil, BHT can inhibit the oxidation of oil products, prevent the formation of sludge and paint film, maintain the lubricating performance and stability of lubricating oil, and extend the service life of equipment. In fuel oil, BHT can prevent the oxidation of fuel and the formation of colloid, ensure the smooth combustion of fuel, and reduce the generation of engine carbon deposits.

5. Other fields: BHT can also be used in coatings, inks and other industries as an antioxidant to prevent the organic components in these products from undergoing oxidation reactions, thereby maintaining the quality and performance of the products. In addition, BHT is also added as an antioxidant to some medicines and feeds to extend their shelf life.
