Yes...propolyne glycol is used in "environmentally" friendly auto antifreeze. 50/50 mix with deionized water will work. Won't kill the dogs if you leave a puddle. Offers decent cooling properties and won't freeze when temps get cold.
I have a gallon of Prestone's auto version. Thought it might be ok for track use, but turns out it is still slippery stuff and not allowed in track bike radiators.
So mix it up and enjoy your "green" coolant.
I used to be fast....now I just dream about it.
