Considered to be, the building blocks of e-liquid, Propylene Glycol (PG) and Vegetable Glycerin (VG) guarantee the pleasure of vaping. Therefore, it is essential to know the meaning of these elements in the liquid to obtain the right ratio. This guide will certainly give you more details on PG/VG.

PG/VG in general

In general, the PG displays perfect fluidity. Its role is to bring out the flavour of the liquid while guaranteeing a good hit for the throat. It must be recognized that the majority of electronic cigarette smokers insist on these last two points.

For its part, the VG is a thick component which guarantees the vaporization of the e-liquid. Because of this, you can expect to get a good amount of vapour each time you vape by opting for a heavy dose of VG. In addition, this element offers more roundness to the liquid.

Understand that PG/VG represents 80-95% of the total composition of the liquid. Add to that, you have to know the difference between the production of vapour and the hit. One depends on the rate of VG while the other depends on the PG.

PG/VG ratio: what is it?

Normally, the PG/VG ratio is expressed as a percentage. It is used to tell you the proportion of PG and VG that can be found inside an e-liquid. The sum of the two elements should give a complete rate of 100%. To go further, you should know that the ratio does not indicate the total amount of PG and VG in the liquid. Rather, it is about the proportion of one to the other.

Therefore, it is recommended that you choose the ratio of PG / VG in the liquid you want to use. In this way, it is easier to find the right bottle while enjoying the pleasure of vaping. Note that the handling of an electronic cigarette can be difficult if you do not have the right level of PG / VG.

Understand the impact of the PG/VG ratio on the liquid

Please note that the pleasure obtained while vaping can greatly depend on the PG/VG ratio. This is why you should take note of the following rates:

  •         100% PG: Provides the maximum hit in the throat, but does not offer much vapour.
  •         100% VG: the liquid makes it possible to make big clouds and almost eliminate the hit on the throat

80          % PG/20% VG: offers a strong throat hit, but a weak vapour

80          % VG/20% PG: the hit is almost not felt unlike very intense steam

70          % PG/30 VG: the liquid produces a good amount of vapour while offering a good hit

70          % VG/30% PG: a large amount of vapour against a light hit

60          % PG/40 VG: the hit is weaker than the vapour produced by the liquid

60          % VG/40 PG: the hit begins to be smoother while the vapour is more intense

50          % PG/50% VG: best for the balance of hit and vapour

What happens in case of the wrong dosage of PG/VG?

The wrong PG/VG dosage can usually manifest itself in two forms. Thus, the use of a liquid with too strong a PG can cause leaks in the airflow. You may also experience fluid swirling in your mouth. This is because the e-liquid can be too fluid.

On the other hand, the resistance of the cigarette can be badly imbibed if the rate of VG is too high. It may even quickly deteriorate the resistance and cause a burning sensation during vaping. It is good to know that a bad level of PG / VG can even affect the flavour of the liquid. Remember that the PG is the one that enhances the flavour of the liquid.

Apart from that, it can be said that the level of PG/VG can have an impact on the health of the smoker. PG can for example lead to drying of the mouth and mucous membranes. Therefore, it is recommended to drink plenty of water after long vaping. To go further, some people may experience gastric pain in the event of PG intolerance.

How to choose the PG/VG of an e-liquid?

The following two points must be taken into account to find the right PG/VG rate in an e-liquid.

PG/ VG         rate and resistance

You are probably aware of the fact that an e-liquid with a higher PG rate can be very fluid. Also, the liquid will be vicious and thick if it is the VG that is more important. In any case, it should be noted that some resistors may favour the PG while others lean more towards the VG.

More precisely, it is more judicious to choose a liquid with a PG higher than 50% of PG if you have a clearomiser endowed with an indirect inhaling resistance. As for an indirect inhaling model, the best option is to use liquid richer in VG. You can even choose VG at 70% if you have large liquid arrivals at the level of the clearomizer.

PG/ VG         rate and potency

The restitution of the energy necessary for vaping depends on the accumulator which heats the resistive wire of the resistance. It is to ensure this that you should take the time to choose the power of your electronic cigarette. The majority of models offered on the current market offer the opportunity to easily adjust the power you need.

The power of the device can always have an impact on the consumption of the liquid. Thus, a strong enough cigarette can quickly consume liquids. But, you will have the possibility of doing a “Dry Hit” if the liquid used has more PG. With a thick liquid, you will need a powerful cigarette with several holes in the resistance. To avoid unpleasant surprises, you are advised not to choose an electronic cigarette that is too weak.
