Propylene glycol maintains generally the same freeze protection and corrosion and algae prevention as ethylene glycol, but has a lower level of toxicity. This type of glycol is more readily disposable than ethylene and safer to handle. Propylene glycol is commonly used in the food industry and applications when the user may come in frequent contact with the fluid.
