A multi-talent

With its unique combination of properties propylene glycol fulfils various roles in different environments. It

  • serves as a solvent
  • connects and stabilises insoluble fluids (emulsifier)
  • helps to bind and transport other substances (excipient)
  • holds and dissolves active ingredients equally in a medium
  • attracts/holds water/moisture (hygroscopic)
  • reduces the freezing point
  • increases the boiling point
  • offers outstanding stability with high flash and boiling points

The propylene glycol molecule is chemically neutral, i.e. it usually does not react with other substances. This is a particularly helpful property when seeking to combine contrasting chemical elements, for example in a perfume, to create a single, homogeneous fluid.

By emulsifying the active ingredients, which otherwise would not mix, the propylene glycol creates a stable homogeneous fluid that will allow the intended final product, be it a face cream or shampoo, for example, to do its job.
