So, ejuice … PG or VG? What rocks your world? What are we even talking about?
Anyone who vapes has noticed the reference to PG and VG on their ejuice labels, but not everyone understands the significance of it. Basically, we are talking about the two main ingredients of most ejuices – Propylene Glycol and Vegetable Glycerin. An eliquid can have one or both, as as well water, nicotine, and other flavorings. More and more vapers stick to a specific ratio of PG and VG, hoping to enjoy the ideal mix for that perfect vaping experience. The big question facing each individual vaper is: how to choose what is best for you.
So what are the benefits of Propylene Glycol and Vegetable Glycerin?
Propylene Glycol (PG) carries the flavour of the ejuice wonderfully well. It is thinner than Vegetable Glycerin and so delivers flavour and throat hit with ease. Propylene Glycol is found in all manner of products – bar soap, mouthwash, body wash, deodorant, vitamins, ointment, as a preservative in foods – even salad dressing. The FDA has stated that PG is generally safe though some users have reported allergic reactions due to the higher rate of sensitivity. Rare side effects of Propylene Glycol include sore throat, nausea, and eczema – but none of these are related to the side effects one experiences after giving up smoking.
Vegetable Glycerin (VG) is thicker than Propylene Glycol and much more viscous, which means – hooray! – bigger and better vapour clouds, which many vapers love. Vegetable Glycerin is derived from vegetables (no surprise there) and so is considered completely natural and safe. Those with dripping atomizers love the VG in their mix because of those big clouds, though it's thick consistency does tend to clog coils. Yes there are side effects but they are usually only experienced in the first few weeks of switching from smoking to vaping. These include a sore throat and dehydration.
The Right Ejuice Combination
While the majority ejuice manufacturers are finding that the 70/30 (PG/VG) ratio is the most satisfying to its customers, some people still like to experiment. More and more people are getting into specific percentage blends of PG and VG and so most vendors will display the percentage on their products – PG first, and VG second. For example: 30/70
Neither PG or VG is 100 percent pure; we’re talking more like 99%, here. That shortfall does affect the flavour however. The less pure it is the more you can taste the impurities, jeopardizing the light, mellow taste that many vapers crave.
