Butylated Hydroxytoluene (BHT) is an antioxidant. Oxygen reacts preferentially with BHT rather than oxidizing fats or oils, thereby protecting them from spoilage. As a food additive, it is used under the E number E321. BHT is used as an antioxidant in products such as cosmetics, pharmaceuticals, rubber and transformer oil.
