What’s Really in Your E-liquid

Our curious mind wants to know what’s inside our E-liquid. No fixed standard exists for E-liquid. You can find different types of brands in the market. All those brands use different fixes of ingredients in those E-liquid. The most common ingredient in e-liquid is Vegetable Glycerin (VG), Propylene Glycol (PG), nicotine and flavoring.

Our bottle of e-liquid contains three main ingredients and also an optional fourth. The three main ingredients are propylene glycol, also called PG. vegetable glycerin, also called VG and artificial flavorings. The fourth and optional ingredient is nicotine.

Propylene glycol

Now we know the ingredients in our e-liquid. First, let’s start with PG propylene glycol is a viscous colorless liquid with a slightly sweet taste. In the vaping realm, PG helps act as a flavor carrier. This ingredient is approved for topical oral and some renowned pharmaceutical preparations in the US and in Europe. Propylene glycol is widely used as a food additive due to how well it retains moisture. Those things also make it a very common ingredient in pharmaceutical drugs and cosmetic products. Now when it comes to day-to-day life, propylene glycol is actually very common. 

Many cosmetic retailers based in the UK use PG and also 57 products due to its natural production. Now, are you a fan of ice-cream or popsicles? Many, if not all, store-bought ice cream contains propylene glycol. If you’ve ever been to a concert or show that uses a fog machine, the solution that goes into it is PG, which essentially makes fog machines giant beeps.

Vegetable Glycerin

The next main ingredient, vegetable glycerin, aka VG, is a sugar alcohol derived from plants. It was first discovered two centuries ago and we have since used this essential ingredient and many day-to-day items. It actually shares many of the same products as PG vegetable glycerin is much thicker than propylene glycol. This is what gives a liquid that almost syrupy consistency VG. That’s why E-liquid creates the vapor-liquid will have a different ratio of VG to PG. The more VG you have, the thicker the liquid. Also, a sweetener for many products and some use VG as an alternative to sugar. VG is also commonly found in low-fat frozen foods to prevent ice crystals from forming. It’s also a very common ingredient in pharmaceutical drugs, including heart medication, suppositories, cough remedies, and anesthetics.


Now let’s move into flavors that make vaping so popular and successful, when it comes to the flavorings that are used in a liquid. It’s actually the same food-grade flavorings that go into everyday food items like fruit gummies. You love to snack, which actually doesn’t contain any fruit rather than a flavoring taste like fruit.


It’s an optional ingredient that is contained in e-liquid. It is optional because many e-liquid don’t have e-liquid. This nicotine contains e-liquid for those who want to quit smoking and take a vapor solo e juice.

The big advantage of e-liquid is you know the exact amount of every ingredient that the bottle contains. In cigarettes, you never know that. Also, cigarettes contain more nicotine than other e-liquid. It’s wise to use nicotine-free e-liquid.

Final word

With thousands of different e-liquid flavors in the market but we don’t know what’s in those liquids. However, the ingredient list on its own can look intimidating. It means vegetable glycerin propylene glycol these on their own sound rather scary. It makes it easy for people to have a quick assumption.

We just understand a lot of things that contain the exact same ingredients as your conventional bottle of liquid.
