What is denatured alcohol or ethanol? The denatured alcohol formula is C2H5OH. It is also called methylated spirit or denatured rectified spirit. Some types of 200 proof alcohol are denatured IPA (Isopropyl Alcohol) and NP Acetate (n-Propyl Acetate). Rubbing alcohol is a type of denatured alcohol. Denatured alcohol is ethanol (grain alcohol) with methanol added. It is called denatured because a poison has been added to the drinkable ethanol for tax reasons. Isopropyl alcohol, also called rubbing alcohol, is not a drinkable alcohol. You can buy denatured ethyl alcohol in the United States online from Lab Alley without an ethyl alcohol permit or a specially denatured alcohol permit, which are basically the same thing. The CAS Registry Number (CASRN or CAS Number) assigned by the Chemical Abstracts Service (CAS) to ethanol is 64-17-5.

Technically, ethanol is not the same as denatured alcohol (methylated spirits). Although the main ingredient in denatured alcohol is ethanol, denatured alcohol is a blend of ethanol and toxic additives that prevent people from drinking it. This type of ethyl alcohol is called denatured alcohol because the natural qualities have been altered to make it unfit for drinking. Normally, the primary additive is methanol, so terms such as "methylated spirits" and "industrial methylated spirits" are used to describe denatured alcohol/ethanol. Other standard additives include Isopropyl Alcohol (IPA)/2-Propanol, Ethyl Acetate, N-Propyl Acetate, Methyl Ethyl Ketone, Acetone and Methyl Isobutyl Ketone. Ethanol is synthesized through the mechanism of hydration of ethylene or produced by fermentation.

Nonbeverage drawback alcoholis pure alcohol, the same as that used for consumption. However, when a manufacturer uses that alcohol in the production of a food, flavor, medicine or perfume that is approved by theNonbeverage Products Laboratoryas unfit for beverage purposes, he or she can claim a return on most of the distilled spirits excise tax paid.
