Propylene glycol is added to food products, cosmetics, and even de-icing agents, like antifreeze. * Hexylene Glycol may affect the liver, kidneys and nervous system. If cloudiness or solubilityissues arise, mix the Propanediol into the water phase and/or increase the temperature. The number one difference between the two glycols is that ethylene glycol is toxic and propylene glycol is not, allowing propylene glycol to be purchased as food grade in addition to the technical or industrial grade.
