Propylene Glycol is one of the main ingredients used in e-juice. The product is odorless, tasteless, colorless, and clear. The mist from Propylene Glycol lingers in the air, taking the form of a vapor. It is considered one of the safer ingredients used in industrial products, including e-juice. The more water that is added to Propylene Glycol, the less intense the taste. The substance on its own, before being diluted is a syrup like liquid. The texture of Propylene Glycol holds the vapors together and keeps them from evaporating, because it acts like a stabilizer.
