What You Need to Know About Vegetable Glycerin and Propylene Glycol in E-Liquids
Both vegetable glycerin (VG) and propylene glycol (PG) are excipients. An excipient is an inactive substance that serves as a medium for a drug or other active substance. An excipient performs several functions in a mixture and may also have its own benefits. An example of an excipient is VG/PG, meaning both substances are vital ingredients in e-liquids although their main role is to serve as a base for mixing nicotine and flavoring.
An excipient agglomerate water droplets efficiently; it glues vapor molecules together to form a visible mist. It also allows various components to dissolve efficiently, then disperses them efficiently as an aerosol. Some excipients have a mild effect on the throat.
Propylene Glycol (PG)
Propylene glycol is a more effective excipient in e-juice blends than vegetable glycerin. You can use a PG/VG mixture, or only vegetable glycerin when creating an e-liquid.
The propylene glycol is less viscous than vegetable glycerin. This means MAX VG e-liquids are absorbed faster by your wick and are less likely to gunk up your coils.
PG is also tasteless and odorless. hence, it does not affect the flavor of an e-juice. E-liquids with a high ratio of PG, therefore, have a rich flavor and good throat hit. However, propylene glycol does not give you huge clouds.
Vegetable Glycerin (VG)
Compared with propylene glycol, vegetable glycerin is a less efficient excipient than propylene glycol. You can create an e-juice with only vegetable glycerin or a blend of VG/PG.
Vegetable glycerin is a very viscous liquid. This means MAX VG e-liquids are more likely to gunk your coils, especially if the e-juice is very sweet. However, vegetable glycerin produces big clouds which makes MAX VG blends perfect for cloud chasers. Vegetable glycerin has a slightly sweet taste which can sometimes affect the flavor of an e-juice.
Mixing Vegetable Glycerin and Propylene Glycol
These two excipients can be combined in the following ratios when making an e-liquid.
- MAX VG – This generally describes an e-juice that contains 100% vegetable glycerin and no propylene glycol or a high percentage of VG. MAX VG e-liquids are often used in cloud competitions. MAX VG e-liquids usually have a weak throat hit. Also, the richness of the flavor may not be intense.
- 80/20 VG/PG – The concentration of VG is still quite high in this type of e-liquids. 80vg e-liquids can be quite thick. This type of e-liquids have the same properties as MAX VG blends. They can be hard on coils especially if the blend is sweet.
- 70/30 VG/PG – This is one of the most used VG/PG ratios in the vaping market, it is almost a standard. This VG/PG ratio gives you a balance of both great cloud production and rich flavor. Depending on the nicotine level that you choose, you can get a good throat hit from these type of e-liquids.
- 50/50 VG/PG – If you’re a novice vaper, this is a good starting point. You get a nice throat hit, rich flavor, and massive cloud production.
- MAX PG – This term is used to describe e-liquids that contain only propylene glycol or a high ratio of this substance. These type of e-liquids have poor cloud production, but they give you a strong flavor. MAX PG e-liquids are preferred by flavor chasers.
