Propylene Glycol molecule

Propylene Glycol (PG) is a clear, colorless, odorless and tasteless fluid obtained from petrochemical sources. It’s also one of the most versatile substances ever created, with uses in the food, cosmetic, pharmaceutical and chemical industries. Since electronic cigarettes hit the market, PG has been one of the main ingredients for E-liquid.

Propylene glycol is used as a base for e-liquids mainly for its emulsifying properties, it keeps other ingredients in suspension which otherwise would not mix with one another. It also allows the atomization process to take place at lower temperatures than the combustion in tobacco cigarettes, and carries nicotine to the lungs.
