Corrosionpedia explains Denatured Alcohol. When ethanol is added some chemical substances, the product is unfit for human consumption. The type of additive will determine whether the denatured alcohol will be used as fuel, a cosmetic ingredient or as a cleaner. Common denaturants used singularly or combined include methanol, gasoline, kerosene, chloroform, gasoline, naphthalene methyl alcohol benzene, butyl alcohol and pyridine.
Making the world better, one answer at a time. Without adequate blood supply the human leg can only survive six hours without blood flow. If blood flow is not re established within those six hours amputation may become necessary.
