Like ethylene glycol and propylene glycol, Glycerine is a non-ionic kosmotrope that forms strong hydrogen bonds with water molecules, competing with water-water hydrogen bonds. This interaction disrupts the formation of ice . The minimum freezing point temperature is about −36 °F (−38 °C) corresponding to 70% Glycerine in water.
