Butylated hydroxyanisole is an antioxidant consisting of a mixture of two isomeric organic compounds, 2-tert-butyl-4-hydroxyanisole and 3-tert-butyl-4-hydroxyanisole. It is prepared from 4-methoxyphenol and isobutylene. It is a waxy solid used in certain amounts as a food additive with the E number E320.It is used as an antioxidant and preservative in food, food packaging, animal feed, and cosmetics, and in rubber and petroleum products. It also is commonly used in medicines, such as isotretinoin (known as Accutane/Roaccutane), lovastatin, and simvastatin.
