Butylated Hydroxytoluene (BHT) is a synthetic phenolic antioxidant commonly added to foods, cosmetics, and packaging to prevent the oxidation of fats and oils, thereby extending their shelf life. It is also used as a preservative in a variety of products, including rubber, petroleum products, and animal feed. BHT is recognized for its effectiveness in maintaining nutrient levels, color, flavor, and odor in food products . It is known to have a melting point of 69-71??C, a boiling point of 265??C, and is soluble in ethanol, acetone, and benzene, but not in water, glycerin, or propylene glycol . BHT is also used in some dietary supplements due to its antioxidant properties . However, it is important to handle BHT with care, as it can cause skin irritation and is considered harmful if swallowed .
