Propylene Glycol (PG) – USP-Grade DIY E-Juice Base
Propylene Glycol is one of the two base liquids used to mix your own e-juice. This is USP/EP pharmaceutical-grade PG at better than 99.8% purity — the same base we use in our handcrafted e-liquid. It is thin and nearly tasteless, so it carries flavor concentrate and nicotine cleanly while delivering a sharper throat hit than vegetable glycerin.
Highlights
- USP/EP pharmaceutical-grade propylene glycol, 99.8%+ purity
- Unflavored and nicotine-free — a pure base for DIY mixing
- Carries flavor and gives a crisp, defined throat hit
- Thins thick high-VG blends for easier wicking
- Available in 50mL, 250mL, and 500mL sizes
What Is Propylene Glycol (PG)?
PG is the thinner of the two e-liquid bases. Mixed with vegetable glycerin (VG), flavor concentrate, and (optionally) liquid nicotine, it becomes finished e-juice. Compared with VG, PG produces less visible vapor but a stronger throat hit and crisper flavor, which is why most balanced recipes use it as part of the base.
How DIY Mixers Use PG
- Build a base. A 50/50 PG/VG split is the common all-rounder for most tanks and pods.
- Dial in throat hit. More PG means a sharper hit and sharper flavor; more VG means smoother, bigger clouds.
- Thin a thick mix. Adding PG loosens a high-VG blend so it wicks faster.
- Dilute concentrates. PG is the standard carrier for flavor concentrates.

Propylene Glycol FAQs
| Q |
What is PG used for in vaping? PG is a base liquid for e-juice. It carries flavor and nicotine, gives a defined throat hit, and is mixed with VG to set the final feel of your blend. |
| Q |
What is the difference between PG and VG? PG is thin, carries flavor sharply, and gives more throat hit. VG is thicker and sweeter and produces bigger clouds. Most recipes blend the two. |
| Q |
Does this PG contain flavor or nicotine? No. This is an unflavored, nicotine-free base. Add flavor concentrate and, if you want it, liquid nicotine separately. |
| Q |
What PG/VG ratio should I use? A 50/50 blend suits most tanks and pods. Go higher in VG for more vapor and a smoother draw, or higher in PG for a sharper throat hit and crisper flavor. |
