2-Di-tert-butyl-4-methylphenol, also known as butylated hydroxytoluene (BHT), is a synthetic antioxidant that is widely used in the food industry. It is a white crystalline solid that is slightly soluble in water. BHT is a lipophilic molecule, meaning it has an affinity for fats and oils.
BHT works by preventing the oxidation of fats and oils. Oxidation can cause spoilage of foods, leading to off-flavors and rancidity. BHT can also help to protect foods from the harmful effects of light and heat.

BHT is found in a variety of foods, including:
