Do It Yourself Glycerine Glycol

PG (PROPYLENE GLYCOLES) AND VG (GLYCERINE VEGETAL, GLYCEROL)
What are the PG and the VG, and what are their differences?

What is PG (propylene glycol)?

PG is generally considered to be safe and non-toxic and is used in a wide range of different consumer products.

PG has many useful properties, including that of being a humectant (which means it helps keep things wet), a preservative and a solvent. Thanks to these properties, it is used in cosmetics, pharmaceuticals, animal and human food, food flavorings and many other products. It is also easy to vaporize, and this has led to its use in asthma inhalers, in fog machines and in vaporizing liquids.

What is VG (vegetable glycerin, glycerol)?

The VG is more viscous than the PG. Like PG, the VG is non-toxic and is generally considered safe in the food industry.

It too has a wide range of uses. This is due to its sweetness, its role as a solvent, the fact of being a preservative and its ability to help things keep moisture.

It is used in pharmaceutical products (such as cough syrups, ointments and creams), cosmetics, such as hand cream and toothpaste, as a component that preserves moisture in cooked foods and as a solvent for things like aromas and food coloring.

Key differences between PG and VG for vaper

Based on their chemistry and their uses, there are many similarities between PG and VG. But there are also several key differences. These differences become important when you are evaluating how much PG and VG you want in your vaping liquid.

Here are five key points to consider when choosing the quantities.

1. The PC gives a hit in the throat (hit) stronger

One of the most important things to consider is that the PC gives a stronger throat hit, more like the traditional cigarette. This feature may not seem pleasant, but it's actually a good thing for many smokers who are trying to make the switch to vape. The hit in the throat (hit) accentuated gives vape a feeling more similar to the feeling that is felt in traditional smoking, and this can facilitate the transition to vaping for new users.

But of course this feature is not a good thing for everyone. VG-based vaping fluids have a much smoother feeling in the throat. Anyone who finds the PG overly irritating should be directed to liquids with a higher VG content. Many long-time vaper are oriented towards liquids with a higher concentration of VG because in this case the hit in the throat (hit) similar to the cigarette becomes a less important factor.

2. The VG increases steam production

While the VG decreases the blow in the throat (hit) that many smokers seek, its greatest benefit is to produce thicker and thicker steam. This is why "cloud chasers", ie those seeking to maximize steam production in vaping, favor liquids with a higher concentration of VG.

For the new vaper, however, have a high concentration of VG and an enormous production of steam, it is not so important. It is therefore a matter of finding the right balance. With little or no VG, steam production will be weak and vaping liquid will not do a good job replicating the sensory experience of smoking.

This is one of the reasons why, liquids addressed to those who are at the beginning of their experience in vape, usually have a concentration of VG from 40% to 60%. With a mixture like this, steam production is good, but it does not produce unnecessarily thick clouds. It also helps you avoid some of the inconveniences of high VG concentrations while still enjoying the benefits of this component.

3. The PG impregnates the cotton of the heads (of the coils) better than the VG

One of the most important drawbacks of liquids with a high VG content is related to the little ease with which they impregnate the cotton of the head. Since the VG is much more viscous than the PG, it takes a significantly longer time to impregnate the cotton of the head.

Every time you make a vapour, consume the liquid which is soaked in the cotton, which is then replaced by the liquid in the tank (of the tank). When you take a new shot, if the cotton has not had time to soak with liquid again, you will have a "dry shot", which has a decidedly ugly taste. Since the PG is much thinner and impregnates the cotton rapidly, this drawback is less likely to occur with a high PG mix. But with a higher percentage of VG mix, cotton requires a longer time to soak each liquid, and "dry shots" are more likely.

In many modern sub-ohm tanks, and especially in regenerable atomizers, this does not occur. These devices have very efficient heads, not subject to this problem. However, if ut
