Propylene Glycol (PG) is the main ingredient in the majority of E-Liquids. It forms the base of the juice to which the flavour and sometimes nicotine are added.
While PG can be used as the base of an E-Liquid on its own, it is often blended with Vegetable Glycerin (VG) which is the second most commonly used ingredient. The ratio of PG and VG used in an E-Liquid has an effect on the vaping experience in five basic ways; flavour intensity, vapour density, throat hit, thickness and cleanliness.
E-liquids with higher levels of PG generally have higher flavour intensity, throat hit and are easier to clean while being thinner and producing less dense clouds.
It is a matter of personal preference whether you prefer E-liquids with high or low levels of PG. Your choice of PG/VG may vary depending on the flavour, for example, most people choose high PG when enjoying tobacco juices as the experience is closer to traditional cigarettes.
The best way to discover your own preference when it comes to PG or VG based E-liquids is to experiment and see for yourself. Medusa Juice has a fantastic selection of E-liquids to choose from with a range of different PG/VG ratios. Feel free to explore our convenient online store and see what combination of flavours and PG/VG appeals to you.
PG stands for “propylene glycol” which is one of the two most common bases for E-liquids along with VG, or “vegetable glycerin”. These bases are the biggest part of any e-liquid and it can be useful to know the ratio being used as this can affect the vaping experience in a number of ways.
The base of each E-liquid typically makes up around 95% of the juice and is usually made up of PG, VG or a combination of both. This base is what produces the clouds of vapour while most of the taste and aroma is blended into this mixture of PG and VG in the form of flavour additives and sometimes nicotine.
While the flavourings and nicotine have the biggest impact on how an E-liquid tastes, the base of PG or VG can make an important difference to how the vaping experience feels. Some of the ways PG affects the experience might be noticeable from the first time you start vaping, while others might not be obvious until you start developing a preference. Either way, it can be very useful to know the percentage of PG or VG used in an E-liquid and how this can change the experience.
All the E-liquids available as part of the fantastic range from Medusa Juice contain a base made up of either PG or VG with the majority using a combination of both. The different percentages or ratios affects the vaping experience by changing the feel on the mouth as throat as well as the flavour and vapour produced.
Propylene Glycol (PG) and Vegetable Glycerin (VG) have their own qualities and it is a matter of personal preference which you prefer and which works best for different flavours. The wide selection available from Medusa Juice offers a great choice of PG/VG ratios as well as flavours and nicotine levels. So you can check out the different combinations and find what works best for you.
Propylene Glycol (PG) is almost odourless, colourless and has a low viscosity unlike the thicker Vegetable Glycerin (VG). This low viscosity makes PG easier when refilling and reduces the risk of build up, or gunk, which can affect the vaping performance.
PG is the most commonly used base for E-liquids as the majority of juices available use it as the main ingredient.
PG is also absorbed faster whether you’re using a wick based device, polyfill or alternatives. This makes the vaping experience quicker to enjoy when using E-liquids with a high amounts of PG. And high PG usually means that the flavour is more intense with less of the sweetness that can affect VG heavy juices.
Vapour density and throat feel are other factors to consider when looking at the percentage of PG in the great range of E-liquids from Medusa Juice. Juices with high PG tend to produce less vapour than those with high VG which is a matter of personal preference but worth considering when making your choices from the selection.
Throat hit is also more noticeable with higher PG which is better for those who enjoy a bold, intense experience. This throat hit makes E-liquids with a high percentage of PG feel more like traditional tobacco.
Blends and More
Combining both VG and PG will often create a happy balance between the advantages of both bases. The different percentages being mixed together will have different effects on the overall flavour, intensity, vapour thickness and throat hit as well as the absorption speed and likelihood of gunk build up.
From a practical perspective the high absorption rate of PG that makes it quick to vape from the moment you refill also means the juice is used faster. The low viscosity help keep E-liquids with a large amount of PG easy to clean, so spills are quicker to deal with as well as keeping the coil and the inside of the tank cleaner.
It is all a matter of individual taste and the best way to discover whether a high ratio of PG is right for you is to experiment with different combinations. Explore the range from Medusa Juice to discover E-liquids with a pure PG base or a variety of mixtures combining PG and VG at different ratios.
It is worth remembering that while Propylene Glycol (PG) is commonly used in foods it can cause minor allergic reactions in some rare cases. If you experience an allergic reaction, such as a rash or swelling, while using PG it is advised to stop use immediately and switch to Vegetable Glycerin (VG).
