Butylated hydroxytoluene BHT CAS 128-37-0, also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. It is often used as a food additive. In addition to this use, BHT is widely used to prevent oxidation in fluids (e.g. fuel, oil). It exists in white crystalline powder.

Application

BHT is often used as food additive, household product ingredient, industrial additive, personal care product/cosmetic ingredient, pesticide ingredient, plastic/Rubber ingredient and Medical/Veterinary/Research etc.
Food additive
BHT is primarily used as an antioxidant food additive. It is approved for use in the U.S. FDA and EU as food additive but forbidden in Japan (since 1958), Romania, Sweden, and Australia etc.
Antioxidant
BHT is also used as an antioxidant in products such as cosmetics, pharmaceuticals, rubber, electrical transformer oil (at 0.35%), and embalming fluid. In the petroleum industry, where BHT is known as the fuel additive AO-29, it is used in hydraulic fluids, turbine and gear oils, and jet fuels. BHT is also used to prevent peroxide formation in diethyl ether and other laboratory chemicals.
