Propylene Oxide based glycols are used in a multitude of different areas for example as solvents, extraction liquids and humectants. They are used as antifreeze agent for refrigerators and sprinkler systems, as solvents and humectants for printing colors and ink-pads as well as plasticers for cellophane. Furthermore Propylene Glycol is used as a component for the production of fire-resistant brake and hydraulic fluids, as a starter molecule for raw materials of colors and paints, as a raw material for de-icing of planes as well as in heating fluids for high-temperature work.
