What Is PG and VG in E-Juice?

By vapeMons June 13th, 2025 21 views

Whether you're new to vaping or a seasoned user, you’ve likely come across the terms PG (Propylene Glycol) and VG (Vegetable Glycerin) while choosing e-liquids. These two base ingredients play a key role in your vaping experience, influencing everything from flavor strength to vapor production. Understanding the differences between PG and VG can help you choose the right e-liquid and device for your needs.

What Is PG in E-Juice?

Propylene Glycol (PG) is a synthetic organic compound commonly used in food and pharmaceutical products. In e-liquids, PG serves as a carrier for flavor and nicotine, offering a thinner consistency that is easy to mix and vaporize.

Characteristics of PG:

  • Strong Flavor Delivery: Enhances flavor intensity for a richer taste.

  • Pronounced Throat Hit: Mimics the sensation of smoking, preferred by ex-smokers.

  • Low Vapor Production: Discreet vapor output, ideal for subtle vaping.

Safety and Side Effects of PG:
PG is FDA-approved and widely recognized as safe. Some users may experience mild throat irritation or dry mouth. Staying hydrated can help alleviate these effects.

What Is VG in E-Juice?

Vegetable Glycerin (VG) is a natural substance derived from vegetable oils. It is thicker than PG and naturally sweet, making it popular among vapers who enjoy dense vapor clouds and a smooth inhale.

Characteristics of VG:

  • High Vapor Production: Produces thick, billowy clouds—great for cloud chasers.

  • Smoother Throat Hit: Softer inhale, suitable for sensitive users.

  • Mild Flavor Muting: The sweetness of VG can slightly mute flavor intensity.

Safety and Side Effects of VG:
VG is also FDA-approved and used in many consumable products. Due to its thickness, it may cause build-up in atomizers, requiring more frequent cleaning.

Choosing the Right PG/VG Ratio

50/50 (Balanced Ratio):
A 50/50 PG/VG blend offers a balanced experience of flavor, vapor, and throat hit. It’s ideal for beginners and works well with most pod systems and low-wattage devices.
