Nicotine e-liquid is a mixture of around 4 different ingredients. You’ll find that it contains water, PG (propylene glycol), Nicotine, VG (vegetable glycerine) and flavouring. You will find that some liquids come with additional ingredients but the main thing to go off are these main substances. The amount of nicotine will depend on the strength of the nicotine you want in your liquid. Let’s start off with a quick example. Let’s say that your liquid comes with around 10% nicotine. Of course, somewhere around 10% of your e-liquid will be flavouring as well but this can depend on how strong you like your vape. These factors combined will tell you how much VG and PG is in your liquid.
What is VG?
VG stands for vegetable glycerin and this is a carbohydrate that comes from plant based oils. VG can also be found in various consumer products, such as cosmetics! VG is normally clear and colourless. It doesn’t smell of anything but it does have a very sweet taste and a high level of viscosity. If you want to know how VG affects your e-juice then you’ll find that VG produces a lot more vapour when compared to PG. The main reason for this is because it is much thicker and it blends better with the flavour that you use. If you are allergic to PG, you will also find that VG is a high quality alternative.
A lot of people ask if VG and flavour combine together to make e-juice, but this is not the case. If you just take some VG and you mix it with some flavour, or drop some into a cartridge, there won’t be any vapour at all. Another question that a lot of people ask is whether or not VG is safe to use. VG has been checked and monitored to the same standards as the USP food grade. It is completely organic and it is naturally sweet. That doesn’t mean that it is made in the same way that sugar is however, because it is metabolized in a completely different way. It won’t raise your level of blood sugar and it isn’t associated with tooth decay either, so you can already start to see how the two are very different.
You should also note that VG can be used in toothpaste, shampoo, cosmetics, pharmaceuticals and plenty of other household items as well. The main reason for this is because it is soluble in both water and alcohol, so it is very easy to blend. The fact that it is so versatile makes it invaluable to a number of things and it can even smooth your skin as well so you know that it is great for a huge number of reasons.
What is PG?
PG is an abbreviation of propylene glycol and it is a well known organic compound. It is completely colourless and it isn’t fully odourless either. It has a very slight odour and a very faint, but very sweet taste. It is miscible with water and it is hygroscopic as well. When you add PG to e-juice, it provides the base you need to dilute the nicotine liquid. A lot of people wonder if PG mixed together with flavour makes e-juice but the truth is that they don’t at all. After all, you can’t just drop your PG into your cartridge, because there would be no vapour at all. The use of PG has been thoroughly researched and it has been used for over 50 years now. Studies have shown that PG has a very low level of toxicity and if you have long term contact with the substance then you will find that it is not irritating to the skin at all. It is possible to be allergic to PG however and this is something that you need to be aware of.
So What’s The Difference Between PG, VG and PG/VG Mix?
VG as an e-liquid is very thick and sweet. VG can also produce huge clouds of vapour at any one time and it is great if you have a sweet tooth that you want to satisfy. PG however is much thinner, it produces more of a hit to your throat as opposed to your tongue and you want something that can mimic the feel of smoking for you then this is certainly it. PG also has a much higher rate of sensitivity, so if you find that some vapours are just too harsh for you then you may want to avoid PG in general. On top of this, PG can give you a bigger hit to the throat and this gives you more flavour as well. This gives you more vapour in general and it is much stickier as well. Not a lot of people do not show allergy symptoms when they use VG but people can show symptoms when they use PG. For example, you may experience a phlegm build-up in their nose and throat and the more PG you use, the more these side effects will be amplified. If you choose 60% and 40% VG and PG however then you will find that this gives you much more flavour and this is the main reason why people choose to combine the two of them. If you find that one combination just isn’t working for you then try and go for 70% and 30% until you find one that is more suited to your needs.
Which One Is Safer?
PG and VG are both used in foods and you can consume them both on a day to day basis. They are both deemed to be very safe but in some cases, people have experienced minor reactions to PG and the main one that you need to look out for is a skin rash. This isn’t a huge deal and there are plenty of skin creams out there that can help you to deal with this. So what’s better? It’s all down to your personal preference. Some may prefer 100% PG and others may prefer 100% VG, but if you are struggling to decide between the two then you may want to go for one that combines the two together so you can be sure to find one that is appropriate.
