Propylene glycol, also called propane-1,2-diol, is a synthetic organic compound. It is a viscous colorless liquid which is nearly odorless but possesses a faintly sweet taste. Chemically it is classed as a diol and is miscible with a broad range of solvents, including water, acetone, and chloroform.
Industrial propylene glycol is used as a heat transfer medium, to control viscosity, to dissolve active agents or protect against corrosion and pressure burst. It is also used as raw material for the production of unsaturated polyester resins (UPR).
It can be used as aircraft de-icer, enabling safe global public transport.
It can be used in paints and coatings, providing sustainable weather and wear protection.
