What is Propylene Glycol and Vegetable Glycerine?

Discover the crucial elements that shape E-Liquids, commonly referred to as vape juice. Uncover the hidden power of these two ingredients that leave a lasting impact. Initially, it's easy to overlook the significance of VG and PG ratios when starting out with vaping. However, once you grasp their importance, you'll never view E-Liquid the same way again.

Don't underestimate the influence of those tiny numbers on the bottle or packaging – they hold the key to your ultimate vaping experience. It's not just about nicotine strength and flavour; even the most delightful flavour can become a disappointment if it's not perfectly matched to your preferred ratio.

What is PG and VG in vape juice?

Propylene Glycol (PG) is a thin liquid that intensifies the flavour of your vape, giving it a more robust and intricate taste. It also provides the familiar throat hit for ex-smokers. However, it's important to balance your PG ratio, as some people prefer a milder throat hit.

PG produces less vapor and requires less heat and power to evaporate compared to VG.

On the other hand, Vegetable Glycerine (VG) is a thicker liquid that ensures a smoother inhale and creates impressive clouds of vapor. This makes it a favourite among cloud chasers in vaping competitions.

One key benefit of VG is its ability to deliver a smoother throat hit. By finding the right balance of VG, you can avoid a harsh sensation. It's worth noting that too much VG can affect the flavour, as it reduces the amount of PG, which means less flavour in your vape.

Is PG and VG safe?

Chemicals may trigger hesitancy and concern, but you probably use them every day without realizing it.

For instance, have you ever considered that PG (propylene glycol) is present in various products? It serves as a preservative in foods, a solvent in medical formulas and beauty products, and even creates the artificial smoke in theatrical productions. PG can be found in your oral hygiene products, some medicinal products, and more!

And what about VG (vegetable glycerin)? This natural compound acts as a sweetener in food, a thickening agent in medicines and creams, and a moisture retainer in beauty products. It's even used in the baking industry to increase moisture levels. VG can be found in soap, hand cream, and dental care products, among others.

Both PG and VG have been deemed safe for human consumption by health and safety bodies across the globe, including the FDA, WHO, and FSA. While there haven't been extensive studies on their safety in vapes, no problems have been reported from inhaling PG vapor.

Although some users may experience dry throat and mouth due to the moisture-absorbing property of PG, staying hydrated solves the issue. Those with sensitivity to PG can choose a 100% VG E-Liquid instead.

However, it's important to note that despite their safety, the debate on vaping these compounds continues. Vaping is still considered less harmful than smoking traditional cigarettes, especially for non-smokers.

Which PG/VG ratio is for me?

Discovering the perfect ratio for an enjoyable vaping experience is crucial. Whether you're a beginner or a seasoned vaper, finding the right balance is key.

For newcomers, a 50VG/50PG ratio is highly recommended. This ratio strikes a harmonious balance between flavour and throat hit, making it ideal for Nicotine Salts. Additionally, it produces less vapour, perfect for those who prefer a more discreet vaping experience. This type of vape juice is best suited for lower powered kits as they are easier to vaporize.

On the other hand, high VG vape juices are thicker and require a higher-powered kit and tank. While they lack in throat hit, they produce impressive clouds, perfect for Sub-Ohm vaping. However, it's important to note that high VG juices are not suitable for Nicotine Salts since the increased power can result in an excessively strong nicotine hit.

If you're seeking a balance between flavour and cloud production, a 70VG/30PG ratio is recommended. However, if you're primarily interested in producing voluminous clouds, an 80VG/20PG ratio is more fitting.

For those who prefer a more discreet vaping experience, high PG vape juices are the way to go as they produce less vapor when exhaled. However, be prepared for a stronger throat hit with these types of E-Liquids.

If you already have a vaping device, it's important to choose a ratio that complements your kit. Those with low-powered kits will benefit from vape juices with higher levels of PG, as it helps to thin the VG and facilitate easier vaporization (e.g., 50/50 or 70/30 ratios). If you have a variable device, you have the freedom to choose whichever ratio you prefer.

Here are some common ratios and their characteristics:
• 50VG/50PG - balanced flavour and throat hit
• 70VG/30PG - more vapor while still enjoying flavour and nicotine
• 75VG/25PG - perfect mix for bold clouds without compromising flavour, nicotine, or throat hit
• 80VG/20PG - popular among cloud chasers with a subtle throat hit but less flavour
• 90VG/10PG - for those seeking massive clouds with a hint of flavour
• Max PG - strongest throat hit and maximum flavor but minimal vapour production
• Max VG - ideal for sub-ohm vaping, creating massive clouds with minimal throat hit for flavour enthusiasts.
