What Are Methylated Spirits?

by Jessica Clifton

Commonly used methylated spirits is a general-purpose alcohol which is not fit for drinking. This is because approximately 10% methanol has been added to it, along with additives such as pyridine, isopropyl alcohol, acetone, methyl ethyl ketone, and methyl isobutyl ketone. The methanol is where the name ‘methylated spirits’ comes from.

Also called denatured alcohol, methylated spirits have these chemicals added to it in order to discourage human consumption by making it bad-tasting, foul-smelling, and nauseating. These chemical additives are also called ‘denaturants’ because they make ethanol undrinkable.

The addition of methanol and pyridine makes ethanol solution denatured, but it does not change the chemical or molecular structure. It is different from the denaturation of proteins in biochemistry wherein the structure of the substance is altered.

What makes denatured alcohol poisonous is the addition of methanol and other substances. Denatured alcohol can cause blindness, brain damage, or even death if consumed. Blue or pink dye is sometimes added to methylated spirits to make it easily identifiable.

What are industrial methylated spirits?

Industrial methylated spirits were originally created to avoid paying the taxes due on alcohol. If an alcohol cannot be consumed, it is exempt from alcohol tax. Denaturing alcohol gives it a legitimate use, as well as enabling the manufacture of cheap ethanol for industrial use.

The difference between methylated spirits for personal use and industrial methylated spirits is its purity or grading. Industrial methylated spirits are pure enough for industrial use in things like printing inks, detergents and dyes. It is mainly used as a cleaning agent or thinning solvent in industries.

In order to buy industrial methylated spirits of high purity grading, you must register your interest with HM Revenue and Customs.
