Propylene glycol, also called propane-1,2-diol, is a synthetic organic compound with the chemical formula C3H8O2. It is a viscous colorless liquid which is nearly odorless but possesses a faintly sweet taste.
Propylene glycol is a clear, colorless and hygroscopic liquid. It contains an asymmetrical carbon atom, so it exists in two enantiomers.
The commercial product is a racemic mixture. Pure optical isomers can be obtained by hydration of optically pure propylene oxide.
The freezing point of water is depressed when mixed with propylene glycol owing to the effects of dissolution of a solute in a solvent (freezing-point depression).
HELM AG has been recording strong growth in monopropylene glycol (MPG) sales over the last years and is now well-established as a major supplier of MPG in Europe. The HELM product range includes both technical grade propylene glycol and food grade propylene glycol (USP/EP). In addition to a high level of flexibility in terms of quantities and short lead times, HELM also offers its contractual partners comprehensive market information and constant product availability. The custom-made supply models for industrial users of MPG are a special feature of the service provided by HELM AG.
Since April 2013 HELM is also able to regularly supply its customers with bio MPG for technical applications.
Examples of applications
Monopropylene glycol (MPG) is used in various industries because of its physical properties, its low freezing point and good digestibility. One application for example is the usage as aircraft de-icing fluid.
The main fields of application for technical grade MPG are polyester resins used in the automotive industry and in shipbuilding. Other technical fields of application are laundry detergents and antifreeze products, where MPG is used due to the fact that it is non-toxic. For food grade MPG, the main field of application is in cosmetics, where it is used as a moisture regulator. Food grade MPG accounts for approx. 43% of total consumption worldwide.
