What is vape juice?

Let’s take this from the top. What is vape juice? First off, vape juice, e-juice, and e-liquid are all the same thing. There is no distinction between them. You will probably also hear people say “juice”. They all mean the same thing. Just different names. It all refers to the liquid that is converted into vapor by an electronic cigarette device. Now we’ll get a bit more into the weeds of ‘what is vape juice’.

There are many types of vape juice. To understand the different types of vape juice you need to have a basic understanding of vape juice ingredients. Vaping liquid is made up of:

  1. Vegetable glycerin
  2.  Propylene glycol 
  3. Food grade flavoring
  4. Nicotine (optional)
  5. Water 

Now, despite the names of the ingredients, there is really nothing unusual. Vapor liquid ingredients are pretty basic. As part of our crash course into ‘what is vape juice’, let’s delve into what these ingredients are.



Propylene glycol, or PG, has been around for a century plus. We have been using it for a number of things. It is GRAS, which stands for generally recognized as safe by the FDA and CDC. In fact, the CDC has studied propylene glycol for a number of years. PG is used for stage smoke and theater workers and entertainers have all had long term exposure. No long-term effects on human health have been noted. Additional studies on vaping are ongoing.

Some people may be sensitive to propylene glycol. It can irritate some people’s skin and eyes. The sensitivity can usually be reduced by switching to a vape juice that has more vegetable glycerin that propylene glycol. Vegetable glycerin, or VG, is milder than PG.

Vegetable glycerin is a clear, odorless liquid that is derived from plant oils. Usually the palm plant family. Like PG, you will find VG in foods, lotions, cosmetics, medications, and more. PG and VG are not “bioacumulative”. That means that levels of PG and VG do not build up in your body and become toxic. They are filtered out by the liver and kidneys. 


The difference between PG and VG essentially boils down to how it vapes. Both are food grade additives used in everything from food to cosmetics to soaps and toothpaste. As a general rule of thumb, PG liquid carries more flavor and delivers a stronger hit. By contrast, VG generates more vapor with a milder hit and not as much flavor as a PG liquid. Today’s vape juice flavors are a blend of VG and PG. The ration varies and how you vape plays a big part in determining the right ratio for you.

vg vs pg vape juice

  • 70 % PG e-liquid - used with standard 1.0 ohm and above e-cig devices. For MTL and beginner vapers.
  • 50 % PG and 50% VG e-liquid - 50/50 blend is generally used with higher performance vapes with 1.0 ohm and up atomizer resistance levels.
  • 70 % VG - perfect combination for both flavor and vapor performance with today’s sub ohm vape mods and tanks.
  • Max VG - less flavor, more vapor. Made for cloud chasing.

Freeman 120 ml e-liquid is a 70 / 30 VG / PG blend. What does that mean?

Quite simply it means that Freeman’s juice is made up of 70% VG and 30 % VG. 

Why did we choose that ratio? 

Because we found it to be ideal for delivering flavor to vapor ratio. 

The VG provides amazing, dense vapor cloud while the PG makes sure that you fully enjoy our vibrant flavors. 


The next vape juice ingredient we want to take a look at is the flavoring. In general, the flavoring makes up 1% to 10% of the total volume of an e-liquid. Vape juice flavors are very concentrated so it does not take much. In fact, you don’t want the flavor to be too strong. Flavor recipes and ratios are similar to cooking recipes. The best flavors are finely tuned, tested, and steeped for distribution and saturation.

The source of the flavoring is very important. Some e-liquid brands and do it yourself DIY vape juice makers get their flavors from the internet. The problem is that you can’t always know the true ingredients of a random flavoring based on the label. The FDA permits food/flavor manufacturers to hold back select, proprietary information. For that reason, it is so important to buy vape juice from professional vapor brands like Freeman.

At Freeman, we have trained and Ph.D. chemists operating in an ISO8 lab. Our labels are accurate, tested, and true. We know everything about all of our spectacular flavors. Every bottle of Freeman is steeped for 7 days before shipping. Steeping allows all of the ingredients to blend and integrate evenly.
