What is Vegetable Glycerin?

Vegetable glycerin (also known as vegetable glycerol or glycerine) is an organic substance extracted from vegetable oils (mostly palm and coconut oils). The compound is clear, colourless, sweet and has an oily consistency.

Its chemical structure reveals atoms of hydrogen, three atoms of carbon and three groups of hydroxide which create hydrogen bounds with water thus leading to the thick, oily formula

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.
