propylene glycol has been used as the base for fog machine liquids and in nebulizers for decades.
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 major point is that we have no studies that show the safety of propylene glycol when inhaled over the long term.
That said, propylene glycol is different from the antifreeze used in cars, which is considered more toxic and not safe.
propylene glycol as a liquid, he told me, is “similar to antifreeze.”
propylene glycol, on the other hand, is used to reduce the toxicity of antifreeze.
The European formula for Fireball has even less: under one gram per kilogram of propylene glycol.
