Chemical and physical properties of propylene glycol

  • Name: Propylene glycol
  • Alternative names: 1,2-propanediol, propane-1,2-diol
  • Molecular formula: C3H8O2
  • Molecular weight: 76,1 g/mol
  • Physical appearance: Colourless and odourless liquid, highly viscous and hygroscopic
  • Boiling point: 187.6 degree Celsius
  • Freezing point: -60 degree Celsius
  • Flash point: 104 degree Celsius
  • Solubility: Miscible with acetone and chloroform; soluble in ether. This compound can also dissolve many essential oils, but is immiscible with fixed oils.
  • Stability: It can be stored safely at cool temperatures by itself or mixed with water, glycerol or ethanol. However, in high temperatures it can oxidise, resulting in several by-products including lactic acid, acetic acid, pyruvic acid and propionaldehyde.
  • Auto-ignition: 371 degree Celsius
  • Decomposition: When heated to decomposition it emits acrid smoke and irritating fumes.

Safety and hazards: how dangerous is propylene glycol?

  • Fire hazard: Combustible and at around 100 degree Celsius, explosive vapour/air mixtures may be formed
  • Chemical hazard: Reacts with strong oxidisers
  • Skin and eye exposure: May cause redness and skin irritation due to dehydration. If first aid is needed after exposure, rinse with plenty of water for several minutes and remove contact lenses if possible.
  • Inhalation risk: Can be irritant to the respiratory tract, but under normal circumstances a harmful contamination of the air will be difficult to achieve due to poor evaporation rates at 20°C
  • Ingestion risk: Generally seen as non-toxic, but in case of ingestion rinse mouth and seek medical advice
  • Storage: As propylene glycol is highly hygroscopic, this compound should be stored in a well-closed container, protected from light, in a cool, dry place.
