Description and Uses
The antioxidant butylated hydroxytoluene is contained in food, adhesive glues, industrial oils and greases, including cutting fluids. Sensitization seems very rare.
Because they prevent rancidity, antioxidants are of great interest to the food industry. For example, butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), and EDTA are frequently used to preserve various foods, such as cheese or fried products. Butylated hydroxytoluene is a powerful inhibitor of lipid peroxidation, yet large doses of it can induce oxidative DNA damage and cancer development in the rat forestomach.
