Vaping has continued to grow in popularity over the years. The trend began around 2011 and has taken flight ever since. Vape accessories and technology have managed to evolve constantly. Vape juice flavors and textures are being played with constantly. With that said the bases for vape juice have pretty much remained the same since the beginning years. Propylene Glycol and Vegetable Glycerin have proved to be immovable. Question is – what goes into your juice? To fully live your vape experience it is best to understand these juice bases. The juice you are looking for may still be out there.

Common principles between these two do exist. Both are odorless liquids mixed with flavor, water and nicotine to create vape juice. They are both non-toxic organic compounds, generally labeled as safe for consumption. Propylene Glycol and Vegetable Glycerin are actually both widely used as food additives in many commercial products. Both PG and VG based juice also have their own positive and negative aspects. 

Propylene Glycol is the more popular base between the two. The consistency of PG based vape juice is relatively thin. It is more easily absorbed by the wicking fabric inside the cartomizer. It takes longer for gunk to build up in your vaporizer or cartomizer with this relatively thin liquid base. Propylene Glycol is also a tasteless, odorless liquid. It does not alter the taste of your flavors in any way. 

Vegetable Glycerin is a considerably thicker liquid with a slightly sweet taste. This could cause flavors to be difficult to detect.  Though that could be an upset, the thicker consistency of vegetable glycerin tends to cause more vapors to be generated from your vaporizer. These thick clouds of smoke are a big plus with the vaping community. 

Propylene Glycol is a powerful humectant. A humectant is a substance, usually a skin lotion or food additive used to prevent the loss of moisture. If used as a base for your juice it tends to dry your mouth and throat when used constantly. PG based juice is also known to cause allergic reactions in some cases. These reactions could stretch from a tingling in the throat to serious irritations. Vegetable Glycerin causes no allergic reactions or irritations at all. Propylene Glycol based juice produces a stronger throat hit, where the throat hit of a VG base is not as strong. Vapers have also been known to complain about a VG base causing a build-up of phlegm in the throat.  

Knowing all this information, a worthy piece of advice is to mix your vape juice centered on the principles of these bases. You can mix the thick plumes of smoke from a VG base with a stronger throat hit of a PG base. At the same time you will be relieving the phlegm build up and sweetness of a VG base. Mixing the thick consistency with the PG’s thinner consistency will make a need for cleaning occur less often. All the information to tailor a mix that suits your needs lies in this article. 

Ultimately, both a propylene glycol and vegetable glycerin base have their advantages and disadvantages. The pro of having these two options lies in mixing the bases at your will, to find what will satisfy you personally. Get experimenting and get vaping.
