What type of glycol is being used? Ethylene (anti-freeze)?

The "fog juice" is commercial fog fluid by LeMaitre. Its a blend of deionized water, propylene glycol, ethylene glycol and triethylene glycol. Cheap fluids (industrial grade glycerol or just propylene glycol) give smoke that doesn't "hang" well and they also gum up the heater element pretty quickly.
