Cigarette alternatives have been taking the world by storm. Vaping has become the norm, but what is it exactly that we’re inhaling? The process of vaping is simple enough: e-juice goes into the tank which is attached to a battery. The battery powers up and heats the atomizer coil up to around 200-400 Fahrenheit, and the e-juice solution is vaporized.
But what is E-juice? E-juice is typically made of Propylene Glycol and Vegetable Glycerin. Propylene Glycol (PG) is colorless, organic compound produced by Propylene Oxide and used to distribute flavorings. PG is most commonly found in solvents, food preservatives, pharmaceutical products, and of course, e-juice.
Vegetable Glycerin (VG) is also a good base for e-juice. It is made from plant oils, such as coconut oil or soy. However, it tends to be more viscous than PG, leading to build up in the tank and coil or even a delay when it comes to vaping because of the extra time needed. On that note, thick consistency of VG can also be a positive thing, leading to thicker cloud production.
Both Propylene Glycol and Vegetable Glycerin are good bases and have their pros and cons. Some manufacturers even mix the two, it is very common. Used alone, PG maintains flavor with smaller vapor cloud production while VG sweetens or dilutes flavor but creates massive clouds, but by combining the two substances you achieve a balance in terms of a flavor and vapor density.
