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!
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!
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), and propionaldehyde (a potentially hazardous substance).
