Propylene Glycol (PG) VS Vegetable Glycerin (VG): A Comprehensive Comparison

If you’re new to vaping, you’ve likely encountered the terms “Propylene Glycol (PG)” and “Vegetable Glycerin (VG)” when exploring e-liquids. These two liquids are the primary components of e-liquids, and understanding their differences is crucial for tailoring your vaping experience. In this comprehensive guide, we’ll dive into the world of PG and VG, comparing Propylene Glycol (PG) vs Vegetable Glycerin (VG) in a detailed manner. Their characteristics, uses, and effects on your vaping journey. If you’re a true vaping enthusiast, we recommend you try exploring 100% VG E Liquid if you are looking for an alternative experience.

Propylene Glycol (PG) VS Vegetable Glycerin (VG)

1. The Basics of PG and VG

Defining PG and VG:

Propylene Glycol (PG) and Vegetable Glycerin (VG) are odorless, colorless liquids commonly found in a wide range of products, including e-liquids, food, and pharmaceuticals.


PG is a synthetic compound, while VG is derived from vegetable oils. Both are generally recognized as safe (GRAS) by the FDA.

2. Viscosity and Thickness

PG Viscosity:

PG is thinner and less viscous than VG. Its low viscosity allows it to be easily absorbed by wicks and atomizers.

VG Viscosity:

VG is thicker and more viscous, resulting in slower absorption by wicks and a smoother, thicker vapor.

3. Vapor Production

PG Vapor Production:

PG produces less vapor compared to VG. This characteristic makes it ideal for discreet vaping and those who prefer less visible exhalations.

VG Vapor Production:

VG excels at producing dense vapor clouds, making it popular among cloud-chasers and vapers who enjoy impressive plumes of vapor.

4. Throat Hit

PG Throat Hit:

PG delivers a stronger throat hit, similar to the sensation experienced when smoking traditional cigarettes. This is favored by many transitioning smokers.

VG Throat Hit:

VG provides a smoother throat hit with less intensity, making it suitable for vapers who prefer a milder sensation.

5. Flavor Intensity

PG Flavor Intensity:

PG is known for its ability to carry and enhance flavors. E-liquids with a higher PG ratio often deliver more pronounced flavor profiles.

VG Flavor Intensity:

VG has a slightly sweet taste, which can slightly influence the overall flavor. However, it may not carry flavors as effectively as PG.

6. Allergies and Sensitivities

PG Allergies:

Some individuals may be sensitive or allergic to PG, experiencing symptoms like throat irritation or skin rashes. PG allergies are relatively uncommon but should be taken into consideration.

VG Allergies:

VG is generally considered safe and rarely causes allergies or sensitivities.

7. Coil Friendliness

PG Coil Friendliness:

PG is less likely to build up on coils and atomizers, resulting in reduced maintenance and longer coil lifespan.

VG Coil Friendliness:

VG is thicker and can lead to faster coil buildup. Regular cleaning and maintenance may be required when using high-VG e-liquids.

8. E-Liquid Ratios

PG/VG Ratios:

E-liquids come in various PG/VG ratios, allowing vapers to customize their experience. Common ratios include 50/50, 70/30, and max VG (often 80/20 or higher).

9. Nicotine Delivery

PG Nicotine Delivery:

PG is effective at carrying nicotine, contributing to a satisfying throat hit. It’s favored by many former smokers.

VG Nicotine Delivery:

VG can dilute nicotine, potentially reducing the throat hit. However, it is essential to select the right nicotine strength to achieve the desired effect.

10. Final Thoughts

Choosing the Right Blend:

The choice between PG and VG, or a blend of both, ultimately depends on your vaping preferences. Consider factors such as throat hit, vapor production, flavor intensity, and any allergies or sensitivities you may have.


Many vapers experiment with different PG/VG ratios to find the ideal balance for their individual preferences. There’s no one-size-fits-all answer, so don’t hesitate to explore various options.


Understanding the differences between Propylene Glycol (PG) and Vegetable Glycerin (VG) is essential for tailoring your vaping experience to your liking. Whether you prioritize throat hit, vapor production, or flavor intensity, selecting the right PG/VG ratio can significantly impact your overall enjoyment of vaping. By experimenting with different blends and staying mindful of any sensitivities, you can find the perfect balance that suits your preferences and enhances your vaping journey.
