FWIW, I have a horizontal bandsaw that I keep in an unheated area for cutoff work.
It has a coolant system and I struggled with what to use for a coolant that would not freeze and destroy the submersible pump. I ended up trying and using RV antifreeze. It isn't cheap on a per gallon basis (about $2.50 per gallon on sale) compared to a water/soluble oil mix so I would not want to use it in a large sump, but for misting or a smaller sump (a few gallons) like my saw, it seems to work fine. RV antifreeze can be drank in smaller quantities so I would think that would be good healthwise for misting, and it certainly doesn't freeze :-). It also contains some anti-corrosives. Most of the coolant is recovered on this saw so I only put a few gallons per year into the sump. The stuff never goes rancid. For large machines with big sumps I think the it is a real struggle to keep coolant especially if the machine is not run a lot.
