Origin of glycol¹

First recorded in 1855–60; glyc(erin) + (alcoh)ol

One key ingredient of the stuff: Propylene glycol, a synthetic liquid that absorbs water.

Propylene glycol is used for a variety of industrial, cosmetic, and food production uses.

The European formula for Fireball has even less: under one gram per kilogram of propylene glycol.

Propylene glycol has been used as the base for fog machine liquids and in nebulizers for decades.

The major point is that we have no studies that show the safety of propylene glycol when inhaled over the long term.

It may also be prepared by oxidizing the trimethylene glycol obtained by the action of hydrobromic acid on allylbromide.

The water formed and the glycol-chlorhydrine distill over and are collected in tubulated receivers.

Glycol is heated in a distillery apparatus to 148 C., and a slow current of dry hydrochloric acid passed through it.

On boiling with water, it decomposes into glycol and trimethylamine.

No glycollic acid, oxalic acid, glycol, or glycerol was produced.
