What’s the Difference Between PG & VG?

PG (Propylene Glycol) & VG (Vegetable Glycerin)

With our new JuicyBox, a question that constantly arises is, “What is PG and VG and how can I tell how much I need for my flavor creation?” Propylene Glycol and Vegetable Glycerin, or PG and VG, are the odorless liquid combined with flavor and nicotine to create e-juice. Both are made up of different consistencies and differ in taste. Many ejuices use a combination of PG/VG with various ratios to create the distinct mouth and throat sensations when vaped.

Propylene Glycol (PG)

This probably isn’t the first time you’ve heard of propylene glycol. PG is a petroleum by-product that is commonly used in household items such as medical products, hand lotions, shampoos, asthma inhalers and pet food.

It’s been known to cause allergic reactions in lot of vapers. If you find yourself coming out in a rash, or suffering other unpleasant reactions after using PG-based e-fluid, you should look at using 100% VG juice instead.

PG is known to have a thinner consistency than VG and has a stronger throat hit. All flavors from the JuicyBox at Glass Gone Wow are suspended in PG, which means every flavor already has PG in it. If the flavors were straight concentrate, then they wouldn’t layer on top of one another and it would take two weeks to steep.

Additionally, PG carries flavorings much better than VG suspended flavorings, and PG makes the flavors more vibrant.

Vegetable Glycerin (VG)

Vegetable glycerin is a natural chemical that is derived from vegetable oil. It can typically be found in sugar replacements, makeup, baked goods, and even toothpaste.

A 2008 study of the toxicity of inhaling aerosolized glycerol found that there were no real impacts on help of VG used in vaping. Unless you are allergic to oils like coconut oil and palm oil, allergic reactions to VG is fairly minimal.

VG liquid is much thicker than PG and it has a slow absorption rate for wicks and cartomizers, which leads it to clog and gunk up vaporizers. Since VG is naturally sweet, it makes it hard to taste e-juice flavorings. Since it’s so thick, you get less of a throat hit when using VG, but significantly more vapor in each hit.

So, if you are planning to use JuicyBox to make a new flavor, consider the following:

  • If you want a bigger throat hit (rough, like a cigarette hit) and more flavor, create a juice with higher PG
  • If you want a smoother throat hit and bigger clouds, create a juice with higher VG.

Most e-juice experts prefer a 30/70 PG/VG ratio, as too much PG will make your vape syrupy and won’t pull through a tank coil well. However, the JuicyBox allows you to take your PG/VG ratios to any level you’d like. Let your Creative Juices Flow!
