What is Propylene Glycol?

​

Propylene glycol is a chemical made by reaction of propylene oxide with water. For more than five decades propylene glycol has had an unsurpassed reputation for safe use in a wide range of consumer products, including foodstuffs, animal feed, cosmetics and pharmaceuticals, as well as industrial applications.

​

Features 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.
