Decoding the Common Chemicals in Vape Juice

As you sift through the hundreds of vape juices for sale, you are faced with long ingredient lists and abbreviations that may not make any sense to you. Fortunately, most e-liquids are made of the same basic components, and once you understand what they are you can read any ingredient list easily.

Propylene Glycol (PG)

This is one of those ingredients that comes with a big intimidating scientific name. However, Propylene Glycol has been widely used in a variety of medical treatments, foods and other products for decades. Repeated studies have shown that it is safe for use and for inhalation, which is why it is used in breathing treatments to carry the actual medicine being administered. It is odorless and mostly flavorless. When heated, it produces the large plumes of vapor that we know and love.

Vegetable Glycerin (VG)

Vegetable glycerin is the plant-based alternative to propylene glycol. It is also an odorlessĀ and mostly flavorless base material that carries the flavors and nicotine in your e-juice. It is slightly sweeter and more viscous than PG, and is typically mixed with PG to create balanced e-liquids.

Flavors

Each e-juice is typically made up of several different flavors blended together to give it its signature taste. These are the same flavorings that are used in many of our most popular foods, including fruit and dessert flavors. Most flavors are suspended in a tiny amount of PG before they are added to your e-liquid so even e-liquids that are “Max VG” will still have a tiny amount of PG in them.

Nicotine

One of the most important ingredients on the list will be nicotine. In this case, it is pure nicotine extracted from tobacco plants that is being used. This is different from actual tobacco because it is a cleaner derivative and can be vaporized without any of the other harmful side effects of smoking tobacco leaves. The amount of nicotine in your e-liquid will be left up to you to decide when you place your order.

These are the main components of any e-liquid. The biggest difference between brands will be where they source their flavors and nicotine from, because you want these ingredients to be pure and safe. You will also find that most e-liquids include a small amount of water in the mix, which is obviously safe for inhalation.
