What is Vegetable Glycerin (VG) in Vape Juice?

Puff Vape

Vegetable Glycerin is sweet-tasting, odourless, colourless and is water soluble. It is commonly used in personal care items, beauty products, low-carb sweet treats, baked goods, as well as countless other applications.

Vegetable glycerin (VG) forms the base carrier fluid. VG is preferred to add features like dense vapour cloud production and smooth inhalation, making it a popular choice among both casual vapers and cloud-chasing enthusiasts.

VG is common among all vape juices and especially dominant in nicotine-free vape juices as it caters to casual users. Also, look for our, “Complete Vape Juice Guide 2025”. This will bring on everything you need to know about vape juices.

1. What is Vegetable Glycerin made of?

What is inside a VG? What is VG made of? These are the common questions we are asked. Vegetable glycerin is derived from plant oils—typically soy, palm, or coconut. It is a type of sugar alcohol and is commonly used for its thickening and stabilising properties. Oils are heated under pressure with water, or with a strong alkali like lye (sodium hydroxide). The final product is purified to be pharmaceutical or food-grade, ensuring it is safe for inhalation under normal use conditions.

2. Is VG safe?

VG is generally recognised as safe by the Government of Canada. Also, Glycerine is classified by the U.S. Food and Drug Administration (FDA) under GRAS (Generally Recognised As Safe).

3. Where VG is used other than vape juices?

Vegetable glycerine has a range of uses beyond E-Liquids for vaping. It's used as an ingredient in food, cosmetics and pharmaceuticals, and it's even used in some laundry detergents!

  • It is used as a Sugar substitute. You can find this in many foods, beverages, bakery items and baked goods.
  • In Beauty products, including makeup, soaps, shampoo, bubble baths, aftershave, and many more. This is used for moistening purposes.
  • It is also used in the pharma industry as this acts as a solvent.
  • In case you pick a pet food, there is are good chance of finding VG.
  • As a thick gel for creams, gel capsule pills, rubs, and jellies.
  • Eye & ear drops, toothpaste, pastes, and many dental care products.

4. How does VG change the E-Liquids and vaping?

 1. Vapor Production:

  • VG is thicker and more viscous than PG. It creates very think, bigger and fluffy clouds. However, to make these bigger clouds out of thick liquid, it also utilised more power and reduced life of the device.  High VG e-liquids aren’t really suited to nic salt e-liquids.

2. Hit:

  • VG provides a smoother throat hit than PG. If you prefer a smoother experience or are sensitive to throat irritation, pick VG as it gives a mild inhale.

3. Flavour Carrying:

  • While VG does not carry flavours as efficiently as PG, its mildly sweet taste can subtly enhance dessert and fruit e-liquid profiles.

4. Moisturising Properties:

  • VG helps prevent the mouth and throat from drying out during vaping sessions.

5. High Boiling Point

  • The high boiling point of 290ºC mandates a stronger heating of e-liquid, requiring a more powerful device.

6. Natural feel:

  • Since VG is plant-derived, it appeals to users seeking more natural or organic vape products.

7. Sweetness:

  • As the glycerine has a little sweetness built, it makes even the flavourless option a little bit sweeter.  A flavour combination of VG is made sweeter with it. Always look for your sweet tooth.

4. VG/PG Ratios in E-Liquids

In general, you get in below ratios:

  • High VG ratio(70VG/30PG):  This combo produces more vapour and smoother hits. Best for direct-to-lung (DTL) vaping with sub-ohm devices.
  • Balanced (50VG/50PG):  This combo offers a balance between vapour production and throat hit. Compatible with most pod systems and beginner devices.
  • High PG (30VG/70PG): This combo produces less vapour but delivers a stronger throat hit and better flavour intensity. Common in salt nicotine e-liquids and are best used with Mouth-to-Lung (MTL) pen-style or pod-style kits.

5. Possible Side Effects:

These are given as a warning sign to prevent any issues, as a few people are allergic to VG.

  • Dehydration:
    • As VG is moisture absorbent, the most common sign is dry mouth or sore throat.
    • Due to dry throat, you may cough more often than usual.
    • Dehydration can cause headaches.
    • These all can can be reduced with increase in water consumption. If the issue still persists you can consult for personal expert advice.
  • Increase in mucus:
    • To maintain moisture, our body produces mucus. You may find occasional Phlegm.
  • Any other allergic reaction:
    • Look for a possible reaction in your nasal cavity.

Conclusion:

When it comes to vaping, VG has been part of it due to the features it offers. Look for all options and make the right educational choice that makes your vaping journey hassle-free.
