Denatured Alcohol 190 Proof (Ethanol Alcohol)

UN1170, Ethanol solution, 3, PGII

Denatured alcohol (or methylated spirits) is ethanol that has additives to make it more poisonous or unpalatable, and thus, undrinkable. Denaturing alcohol does not chemically alter the ethanol molecule. Rather, the ethanol is mixed with other chemicals to form an undrinkable mixture.

Product History: Denatured alcohol is not, in itself, a preferred product — that is, it is not something which would be normally demanded if given the alternative of normal ethanol. Denatured alcohol and its manufacture are a public policy compromise. The supply and demand for denatured alcohol arises from the fact that normal alcohol (which in everyday language refers specifically to ethanol, suitable for human consumption as a drink) is usually very expensive compared to similar chemicals, being highly taxed for revenue and public health policy purposes. Pure ethanol would have the same health hazards as any other high concentration alcohol. As a result, if pure ethanol were made cheaply available as a fuel or solvent, people would drink it.
