Can ethylene glycol, no mix with water, used as a machining, grinding coolant?
It's used in anti-Freeze in cars and highly toxic if ingested!
Material we're grinding reacts with water!

It will absorb water from the air, and you REALLY don't want to breathe the
mist.

So, I would not do it. There must be something better.

Google "neat grinding fluid" There are loads out there, but some may be
better than others for your application.

Tiny droplets will become airborne and you will breathe them in. No, forget it.

There has to be a lot of other non toxic and no water fluids.

Thank you for all the responses!
Seems to me the Propylene glycol is a better option, but not sure how it behaves for grinding, slicing ceramics!
Seems to me the industry switched from ethylene glycol to propylene glycol, far as anti-freeze and deicing goes. Safer!

Oral administration

The acute oral toxicity of propylene glycol is very low, and large quantities are required to cause perceptible health damage in humans; propylene glycol is metabolized in the human body into pyruvic acid (a normal part of the glucose-metabolism process, readily converted to energy), acetic acid (handled by ethanol-metabolism), lactic acid (a normal acid generally abundant during digestion),[20] and propionaldehyde (a potentially hazardous substance).

Ethylene glycol is still used in automotive antifreeze. I used
Prestone Low Tox a few years back,it was made from propylene gylcol. I
had to change mny water pump once a year, the stuff tore up seals like
crazy. About 2 years ago I could no longer find it at any local
store, auto parts or dept store. So I switched back to the ethylene
glycol stuff.

Google "grinding oil". I have used Mobilgrind and Castrol "llogrind".

Indeed it is. Dogs in particular die very miserable deaths when they
consume it.

No dogs or cats in the shop, only rats!
Machinist rats! Bruhaha!
