Product details of Propylene Glycol (30ml PG – Repacked DOW Propylene Glycol USP/EP)
PG (propylene glycol) and VG (vegetable glycerin) are the two mostly widely used e-liquid bases. The bases hold the flavor in suspension so your e-cigarette can produce those nice clouds of smoke-like vapor. Both propylene glycol and vegetable glycerin are non-toxic organic compounds and generally considered safe for consumption. In fact, they are widely used as food additives in a variety of commercially available products.
The two fluids have a different consistency to each other, and also have a slightly different taste. They have distinct mouth and throat sensations when vaped. It’s hard to say which one of the two is the best, because it ultimately comes down to personal preference. Most modern e-liquid uses a combination of the two fluids, though the ratio can vary dramatically. Some vaping set-ups can only work with a certain level of PG and VG. Choosing the wrong PG/VG ratio can put first-timers off so be careful to choose the right level for your equipment.
PG-based e-liquid is the most popular of the two. Due to the fact that propylene glycol is relatively thin in consistency, this kind of e-liquid is runnier than the VG variety, and is more easily absorbed by the polyfill fabric inside the cartomizer. The low density of the juice also means that gunk doesn’t build up on the heating element of your e-cigarette as fast as it does when thicker vegetable glycerin liquid is used. Propylene glycol is a tasteless odorless substance, so it doesn’t alter the flavor of the e-liquid in any way. It’s also a powerful humectant, so while it will dry your mouth and throat if used consistently, PG also produces a stronger throat hit, similar to that of tobacco cigarettes. On the down side, propylene glycol is known to cause allergic reactions in some e-cig users. These can vary from minor reactions, like a tingling sensation in the throat, to serious irritations on various parts of the body. If you experience any unusual symptoms after vaping PG e-liquid, it’s best to stop using it immediately and switch to vegetable glycerin.
It’s fair to say the vaping community is evenly divided when it comes to e-liquid preference. Some enjoy the smoking-like throat hit of vaping propylene glycol juices, while others prefer the thick plumes of vapor and the sweet taste of vegetable glycerin. It’s hard to say which one of the two is the best, because it ultimately comes down to personal preference. I’d suggest you start with a PG e-liquid, especially if you’re looking for an experience close to smoking, and try out a VG juice along the way, just to see what you’re missing out on. To get the best of both worlds, many vapers prefer a PG/VG mix, in different amounts. This way, they get a decent throat hit as well as pillowy clouds of thick vapor.
