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.
The evidence on BHT is a bit more reassuring. Despite its structural similarity to BHA, there is no conclusive evidence that it is carcinogenic. The IARC lists it as unclassifiable for humans, but finds that there is limited evidence that it causes cancer in animals.
