Description
BHT occurs as a white, crystalline solid. It is freely soluble in alcohol, and insoluble in water and in propylene glycol.
Applications
2,6-di-tert-butyl-4-methylphenol is also known as antioxidant 264 and Butylated Hydroxytoluene (BHT). Antioxidant 264 is an excellent general-purpose phenolic antioxidant, non-toxic, non-flammable, non-corrosive, and has good storage stability, it can inhibit or delay the oxidative degradation of plastic or rubber and prolong the service life. BHT is an excellent antioxidant additive for various petroleum products. It is widely used in various lubricating oils, gasoline, paraffin wax and various raw oils to prevent the acid value or viscosity of lubricating oil and fuel oil from rising. Used as food antioxidant and stabilizer in food-grade plastics and packaged foods, it can delay the rancidity of food. BHT can also be used for polyethylene (PE), polystyrene (PS), polypropylene (PP), polyvinyl chloride, ABS resin, polyester, cellulose resin and foam (especially white or light-colored products), food Grade plastics, natural rubber, synthetic rubber (styrene-butadiene rubber, nitrile rubber, polyurethane, butadiene rubber, etc.), animal and vegetable fats and oils, and food and cosmetics containing animal and vegetable fats.
