About Propanediol

Propanediol can refer to any of its 3 isomeric compounds. The 3 isomers of propanediol are:

  • 1,2-Propanediol commonly known as propylene glycol
  • 2,2-Propanediol commonly known as geminal diol
  • 1,3-Propanediol commonly known as trimethylene glycol

ReAgent stocks 1,2-propanediol. Widely referred to as propylene glycol, it is a synthetic organic compound and a liquid alcohol that finds use in a large variety of industries. Its other names include methyl ethyl glycol (MEG), methylethylene glycol and 1,2-dihydroxypropane.

Chemically, it is classified as a diol because of its 2 hydroxyl groups (-OH). Physically, it appears as a colourless, odourless and viscous liquid with a faintly sweet taste. It is miscible with most solvents, absorbs water easily and is generally considered non-toxic despite its close relation to ethylene glycol.

The chemical properties of propylene glycol are:

  • IUPAC Name: Propane-1,2-Diol
  • Chemical Formula: C3H8O2
  • Boiling Point: 188.2°C
  • Melting Point: -59°C
  • E Number: E1520
  • CAS Number: 57-77-6

In addition to these properties, this compound has low volatility and is non-corrosive. Its non-toxic nature is further shown by the fact that it has its own E Number.

Uses of Propylene Glycol

Propane-1,2-diol is most famous for its use in antifreeze, where it replaces ethylene glycol to create a non-toxic and safer solution. This is especially important given the number of fatal accidents that happen when pets, for example, lap up spilt ethylene glycol-based antifreeze from the ground.

As well as its non-toxic nature, its miscibility with solvents makes this compound well-suited to a huge range of applications across many different industries. It is used in:

  • Pharmaceuticals
  • Food preservatives and humectants
  • E-Cigarettes
  • Polyester resins
  • Artificial smoke machines
  • Veterinary oral treatments
  • De-icing fluids

Safety Precautions

As when handling any chemical material, care should be taken when handling propanediol.  Always read the MSDS (Material Safety Data Sheet) before working with this compound.

Although it is non-toxic, you should always keep propylene glycol out of the reach of children and animals.  Wear appropriate protective clothing when handling this compound including protective overalls, compatible safety gloves, approved eye protection and safety footwear.

All staff at ReAgent are fully trained in the safe handling of hazardous and non-hazardous chemicals.  ReAgent complies with all current safety regulations and is proud of its excellent safety record.
