Check the ingredients on the next can/bottle of soda pop you drink. Also note that they are all poisonous in certain quantities. Propylene is considered food grade because it is far less toxic than the ethylene. Propylene is made for RV water drains to protect from freezing, ethylene is what you run in your car (unless you choose the more "green/safe" variety).
