Denatured Alcohol - Consumption and Toxicity

Consumption and Toxicity

Despite its poisonous nature, denatured alcohol is sometimes consumed as a surrogate alcohol, which can result in blindness or death if the denatured alcohol contains methanol. This happened during Prohibition, when the U.S. government used methanol in industrial alcohols manufactured in the United States. To help prevent this, denatonium is often added to give the substance an extremely bitter flavor. Substances such as pyridine help to give the mixture an unpleasant odor, and emetic (vomiting) agents such as syrup of ipecac may also be included.
