Denatured alcohol, sometimes referred to as methylated spirits, includes specific additives that make it non-drinkable. This form of ethanol has a bad taste, smells foul, and is poisonous if ingested. The additives exist to deter individuals from attempting to consume it for recreational purposes. Typically applied as a solvent, denatured alcohol is suitable for numerous application needs. Many forms contain approximately 10 percent methanol as the additive, rather than other common alternatives such as isopropyl alcohol, denatonium, methyl isobutyl ketone, and acetone. Denatured alcohol is used in wood sanding, small camping stove fuel, cleaning aids, application as a solvent, and in the production of some fuels.
