Introduction to PG and VG

Propylene Glycol (PG) and Vegetable Glycerin (VG) are the foundational components of e-liquid, playing pivotal roles in the overall vaping experience. They're not just fillers; they're essential to what makes vaping enjoyable and satisfying.

PG is renowned for its ability to carry flavours and mimic the throat hit of traditional smoking, making it a vital ingredient for those transitioning from cigarettes. Meanwhile, VG is all about the vapour; it's what gives e-liquid its satisfying clouds and a subtly sweet aftertaste.

Flavour Carrier

PG is a colourless, odourless substance with a thin consistency. It's the flavour carrier of the duo, ensuring that each puff is packed with the taste profiles vapers love. Its low viscosity means it's less likely to clog up vaping devices, keeping maintenance to a minimum.

Throat Hit Enhancer

For many, the 'throat hit' is crucial, and PG delivers. It provides a sensation akin to the catch in the throat that smokers experience, an essential feature for those using vaping as a stepping stone away from tobacco. Plus, PG's effectiveness at lower temperatures makes it a go-to for mouth-to-lung (MTL) devices. Learn more about the signs of experiencing vapers tongue.

Vapour Producer

VG takes centre stage when it comes to vapour production. Its thick consistency leads to denser clouds, a must for cloud chasers and those who prefer direct-lung (DL) vaping styles. The smoothness of VG also makes it gentle on the throat, providing a more mellow experience. Understand the causes of vapers tongue and ways to overcome it.

Sweetness Additive

Though VG doesn't carry flavour as effectively as PG, it compensates with a natural sweetness. This characteristic can enhance the overall flavour profile of e-liquid, providing a pleasing aftertaste that isn't overpowering but complements the complexity of the flavours.

Finding the Right Balance

Personal Preference

The PG/VG ratio in e-liquid can significantly alter the vaping experience. High PG blends favour flavour and throat hit, while high VG juices cater to those looking for smoother inhales and thicker clouds. Finding the right balance is a personal journey for every vaper. Discover e-liquid flavour changes to alleviate symptoms of vapers tongue.

Device Compatibility

Not all devices are created equal when it comes to handling PG or VG. While PG is generally more versatile, some modern tanks and coils are specifically designed to handle the viscosity of VG-heavy e-liquids. It's crucial to consider your device when choosing your ideal PG/VG ratio. Learn about the role of strong neutral scents in rescuing your palate.

Health and Safety

General Safety

PG and VG are considered safe for use in many consumer products, including foods, cosmetics, and pharmaceuticals. However, inhaling them as vapour presents a different exposure route that continues to be studied. Read about the impact of climate on mouth dryness.

Irritation Potential

Some individuals may find that high levels of PG cause throat irritation or dryness. It's essential to monitor how your body reacts to different e-liquid compositions, especially if you're prone to sensitivities. Find out more about the treatment for vapers tongue.

PG/VG and Vapers Tongue

PG/VG ratio

Impact on Flavour Perception

Vapers tongue, a temporary condition where one's ability to taste e-liquid flavours diminishes, can be influenced by the PG/VG ratio. High VG content may contribute to a milder flavour experience, which, for some, might lead to vapers tongue.

Solution and Prevention

Adjusting the PG/VG balance could help prevent or alleviate vapers tongue. For those affected, a switch to a higher PG content might be beneficial, as it can enhance flavour delivery and may help refresh the palate. Sense Hero's spray offers a quick fix for dryness and palate cleansing, providing relief for vapers tongue sufferers. Learn how to prevent vapers tongue.
