What is the percent alcohol in denatured alcohol?

Denatured alcohol typically contains about 90-95% ethanol, but it is not safe for consumption due to the addition of toxic substances to make it unpalatable. The exact percentage can vary depending on the specific formulation and the denaturants used. Common denaturants include methanol, isopropyl alcohol, or other chemicals that render the ethanol undrinkable. Always refer to the product label for precise information on its composition.
