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.

About 10% of people are still conscious without any cerebral hypoxic symptoms at blood flow levels of 20-25 ml/100 gm/min, and about 5% are still conscious without any cerebral hypoxic symptoms at blood flow levels as low as 15-20 ml/100 gm/min (see Figure 5).
