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.
BHT is so toxic it's already been banned in many other countries. In the US, it's often used as a preservative in chewing gum and other processed foods. BHT has been linked to organ system toxicity, including kidney and liver damage, hyperactivity in children, and may be carcinogenic.
