Propylene glycol vs distilled water
WebbEthylene glycol is a synthetic liquid compound that absorbs water and is an odorless clear solution that has a sweet taste and when swallowed it creates a water feeling on the tongue. Propylene glycol is often used as a "generally recognized safe" alternative to ethylene glycol. WebbA formulation of 96.0 percent food grade propylene glycol plus food grade corrosion inhibitors. Solutions of this in water provide freeze protection to below -50°C (-60°F) and burst protection to below -73°C (-100°F).
