Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. European and U.S. regulations allow small amounts to be used as a food additive.
Antioxidants are necessary in these materials due to the unsaturation contained in the diene molecule. BHT is usually the antioxidant of choice. Where higher processing or end use temperatures are a factor, higher molecular weight hindered phenols may be used with BHT.
