Compare PG and VG E-Juices in Disposable E-cigarettes

As the primary components of favored disposable e-cigarettes, Propylene Glycol (PG) and Vegetable Glycerin (VG) play crucial roles in enhancing subsequent flavors. E-liquids are categorized into PG and VG e-liquids with respective distinct characteristics. Today’s blog aims to provide a better understanding of these two types of e-liquids and related knowledge. To help you better comprehend PG and VG e-liquids, a comparison between Propylene Glycol e-liquid and Vegetable Glycerin e-liquid will be conducted.

1. Propylene Glycol (PG) vs. Vegetable Glycerin (VG)

Propylene Glycol is a chemical compound synthesized from propane oxidation. It is colorless, nearly tasteless and has low viscosity with relatively high safety. PG finds applications in solvents, moisturizers, foods, tobacco products and e-liquids in disposable e-cigarettes.

Vegetable Glycerin is a natural liquid extracted from plant oils. It is relatively clear, slightly sweet and more viscous than VG. Like Propylene Glycol, VG is an edible organic compound. It is primarily used in cosmetics, food production and e-liquids.

2. Propylene Glycol (PG) E-liquid

Compared to Vegetable Glycerin (VG), Propylene Glycol (PG) has a lower density, meaning there is less residue when using disposable e-cigarettes predominantly composed of PG. Due to its lower density and viscosity, it is absorbed more quickly by absorbent materials like cotton. PG e-liquids can produce the highest flavor intensity and throat hit, providing a warmer vaping experience. But a notable drawback is the limited vapor production.

3. Vegetable Glycerin (VG) E-liquid

Vegetable Glycerin (VG) has a much higher viscosity than PG, making it more suitable for users who prefer denser and higher-density vapor clouds. Unlike PG, VG has a milder throat hit and tends to offer relatively less sweet flavors. VG e-liquids leave more residues in the device compared to PG. Users should note that in devices using absorbent materials, it is advisable to wait for additional time after filling before starting to vape, allowing the e-liquid in disposable e-cigarettes to be fully absorbed.

4. Safety and Health Concerns of Two E-liquids in Disposable E-cigarettes

Both Propylene Glycol (PG) and Vegetable Glycerin (VG) are considered safe and acceptable for ingestion. They are widely used in various food, pharmaceutical, and cosmetic products. Yet there may be rare cases of mild allergic reactions to PG. Users must exercise caution when choosing. If any symptoms occur while vaping PG-based e-liquids, stop immediately to provide sufficient time for the body to recover, and switch to VG-based e-liquids.

Conclusion

Ensuring a safe voyage through the vaping landscape, we addressed the safety and health concerns associated with PG and VG. Both compounds hold the esteemed status of safety and acceptability for ingestion, ingrained in various consumables. Despite their generally safe nature, a cautionary note resonates – rare cases of mild allergic reactions to PG may occur. Users are urged to be vigilant, promptly transitioning to VG-based e-liquid.
