What is PG and VG?

If you are new to the world of electronic cigarette smoking, it is highly possible that this is your first time reading about PG and VG. However, as soon as you start browsing the catalogues of online electronic cigarette suppliers out there, you will frequently encounter these two terms. Before you purchase your first e-cigarette and all of the essential components that go with it, it is important that you take the time to know the answer first to the question: what are PG and VG? This is because PG and VG are the main bases of e-liquid solutions, and both can greatly impact your vaping experience.

How E-Liquids Turn To Vapor

So what are PG and VG? Before we answer this question that has been on your mind ever since you first entered the world of electronic cigarettes, let us first take a closer look at how electronic cigarettes work. E-liquids, which are the nicotine base solutions used in electronic cigarettes, need to be placed in a container in order for it to function properly. This container, or carrier, holds this solution in suspension. When you take a puff on your e cig, heat will then be applied onto the nicotine base solution in order to produce vapor.

All about PG and VG

PG stands for Propylene Glycol, and VG stands for Vegetable Glycerin. These two components is what make up most of the e-liquid that your electronic cigarette contains. Both of these main components are essentially non-toxic, meaning that they are safe for the use of human beings. Aside from this, PG and VG also have the ability to be easily emulsified with other ingredients as well as to carry various flavors well.

Both of these e-liquid components have been deemed by the Food and Drug Administration (FDA) as “Generally Recognized as Safe” for human consumption. This means that even before you have started using electronic cigarettes and inhaling the vapor produced by the e-liquids, you have already consumed them through processed food or you might have already applied them onto your skin by using various cosmetic products.

The Benefits of Propylene Glycol

One of the things that set PG apart from VG is that it has a somewhat lower level of flavor of its own. This is because PG is thinner compared to VG. E-liquids that are made up of pure Propylene Glycol.

This type of e-cigarettes have smaller openings where the e-liquid travels in order for it to reach the heating coil. When use all on its own, the vapor that is produced by Propylene Glycol has a thinner mouth feel and taste.

The Benefits of Vegetable Glycerin

When used on its own, you will find that Vegetable Glycerin is a little on the sweet side. So when used as a component in e-liquids, VG makes it a bit harder for the notes of certain flavors to be detected. Aside from this, VG is also slightly thicker compared to PG, so the vapor is thicker. As a result of the thicker amount of vapor that Vegetable Glycerin produces, you may think that e-liquids comprised purely or mostly of VG produces a higher amount of vapor compared to that of e-liquids made purely or mostly of PG. Some people also prefer VG-based e-liquids because they have certain allergies to Propylene Glycol and other chemical compounds.

Which is Better, PG or VG?

We cannot give you the exact answer, as your choice and decision will all boil down to your personal preference, your e cig smoking requirements, and your tastes. One of the most important things that you need to know about Propylene Glycol is that this is a man made synthetic chemical, while Vegetable Glycerin, as you can already infer by its term, is a component derived from plants.

If you know that you are sensitive or if you have allergies to chemical compounds, it may be better for you to use an e-liquid comprised purely or mostly of VG. If you have experienced any adverse reactions such as throat dryness when using an e-liquid based from Propylene Glycol, it is definitely a wise choice to switch over immediately to an e-liquid based from Vegetable Glycerin. On the other hand, if you are not sensitive or allergic to PG and you would want something that will enhance the flavors of your e-liquids, then you might want to go for a PG-based e-liquid.

Vegetable Glycerin (VG) - Glycerol is a chemical compound also commonly called vegetable glycerin or glycerine. It is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. In foods and beverages, glycerol serves as a solvent and sweetener, and may help preserve foods. It is also used as filler in commercially prepared low-fat foods, and as a thickening agent in liqueurs. Glycerol is used to provide the vapor mist that looks like smoke and to suspend flavor.

Propylene Glycol (PG) - The Food and Drug Administration (FDA) has determined propylene glycol to be safe for use in food and propylene glycol is used in cosmetics and medicines. It is used in food coloring, and flavoring, as an additive to keep food, medicines and cosmetics moist, and in machines that simulate smoke. Propylene glycol also provides the vapor mist that looks like smoke and to suspend flavors.

Base Mix Help PG:

The more PG in a mix will make the liquid thinner and produce more throat hit. (Nicotine and Menthol also increase throat hit) VG: The more VG in a mix will make the liquid thicker, throat hit will be less and the vapor produced will be much greater. We do not recommend that your purchase 100% PG unless you plan on mixing it with your own ratio of VG. 100%. PG will produce no vapors and cause your liquid to taste burnt. If you are unsure of how to choose a base, we HIGHLY recommend that you chose our house blend that has already proven to be a great producer of vapor and provide you with a satisfying throat hit.

Burnt or Peppery Taste:
Keep your atomizers / cartomizers wet. Dry atomizers or cartomizers can give a burnt or peppery taste and lower the lifetime of your device. A peppery taste is also a sign that your liquid needs to steep longer, or you are getting a small amount of E-Liquid in your mouth from your atomizer / cartomizer.

This can result in leakage and may need to clean your device.
