What Are VG and PG in Vapes? A Basic Guide
Share
Whether you are an experienced vaper or just starting out, this article will provide you with more inspiration for optimizing your vaping experience.
In fact, not all e-liquids are created equal. Choosing e-liquid is more than just deciding what flavor to try.
But don't worry, it's not complicated.
All e-liquids are primarily composed of two core substances: VG and PG. Different ratios of these two components will result in a unique user experience. The key is to understand what you want and find the most suitable ratio.
What is VG?
VG stands for Vegetable Glycerin, also known as glycerin or glycerol. This is a natural chemical extracted from vegetable oils, widely used in cosmetics, deodorants, moisturizers, bath liquids, toothpaste, and other daily necessities.
In e-liquids, the main role of VG is to control the density of the vapor. It is thicker than PG, and a higher content results in denser vapor and a smoother feeling when inhaled.
However, high VG e-liquids can also present some minor issues. For example, some users may experience dry mouth or mild dehydration. This side effect is easily resolved by drinking more water. Staying well-hydrated is a good habit, whether you vape or not.
It's important to note that high VG e-liquids can cause atomizer coils to clog, so ensure your device is compatible with high VG concentrations.
Although research on the health effects of inhaling VG is ongoing, the UK Food Standards Agency (FSA) has recognized glycerin as a safe additive, with low toxicity and safe for consumption.
What is PG?
PG (Propylene Glycol), like VG, is a common chemical found in products such as toothpaste, pet food, and shampoo. In e-liquids, PG plays a slightly different role.
PG is thinner than VG and provides a stronger "throat hit" when inhaled. This throat hit sensation is similar to that of smoking, making it very suitable for those accustomed to nicotine.
Additionally, PG is superior to VG in carrying flavor. High PG e-liquids typically deliver a richer, more noticeable taste.
Although PG itself is colorless and odorless, its main function is to absorb and retain moisture. Inhaling high PG e-liquids may also lead to dry mouth or a sore throat, but these symptoms usually subside quickly with increased water intake.
PG is widely used as a food additive and has been deemed safe by the UK Food Standards Agency and EU food additive regulations.
The Significance of PG and VG Ratios in Vaping
When purchasing e-liquid, you might notice ratios indicated on the packaging, such as 60/40, which means the e-liquid contains 60% VG and 40% PG. Variations in e-liquid ratios result in different vaping experiences, as described below:
Smoothness
High VG e-liquids, due to their thickness, are smoother to inhale. They produce a large and dense amount of vapor, perfect for users who enjoy a "big cloud" experience. However, a large amount of vapor can sometimes mask or weaken the flavor.
Throat Hit
PG excels at delivering a nicotine-related throat hit, suitable for users who enjoy this sensation. If you prioritize this physical feeling, choose e-liquids with a high PG ratio.
Flavor Delivery
PG, as a flavor carrier, is more effective in enhancing e-liquid flavors. High PG e-liquids typically have a more pronounced taste, while high VG e-liquids may have a relatively softer flavor.
How to Choose the Right Ratio for You?
The following factors can help you choose the appropriate VG and PG ratio:
Device Compatibility
High VG e-liquids can clog smaller atomizer coils. It is recommended to use high-power devices such as Sub-Ohm atomizers to better handle high VG e-liquids.
Personal Sensitivity
Everyone's sensitivity to VG and PG differs. Some people may be more sensitive to PG, experiencing throat irritation or skin allergies. If you know you are prone to sensitivity, prioritize high VG e-liquids.
Vaping Occasion
If you want to vape discreetly in public, it is advisable to choose e-liquids with a high PG ratio. High PG e-liquids produce less vapor, making them easier to conceal.
Summary
The ratio of VG to PG significantly impacts your vaping experience. Understanding the differences between these components and ratios can help you better control vapor production, flavor intensity, and the smoothness of your inhale.
Experiment with different ratios to find the e-liquid that suits you best, making your vaping experience more enjoyable!
