Understanding Glycerin and Propylene Glycol
Introduction to Glycerin and Propylene Glycol
Glycerin and propylene glycol (PG) are big players in the vape world. They’re the heart and soul of e-liquids, shaping how they taste and the clouds they make.
Glycerin, or vegetable glycerin (VG) if you’re fancy, comes from plants or is born from propylene. It’s a moisture lover and skin’s best friend, which is why you find it in lotions and soaps (Sanco Industries).
Propylene glycol is whipped up from propylene oxide, clear as day and sweet on the tongue. It’s kind of like glycerin’s edgier cousin—more toxic, but useful in tiny amounts. You’ll see it in stuff like antifreeze because it doesn’t mind the cold (Sanco Industries).
Properties and Composition
VG and PG have their own vibes, making them fit for vapers everywhere.

Knowing what VG and PG bring to the table helps vapers choose what suits their taste and keeps things safe.
It’s especially important for folks dealing with things like vaping with asthma or worrying about vaping and oral health.
Glycerin vs. Propylene Glycol
Deciding between vegetable glycerin (VG) and propylene glycol (PG) for vaping isn’t as simple as it seems. Let’s break down their origins, safety stuff, and what could make or break your choice.
Natural vs. Synthetic
Vegetable Glycerin (VG):
You’re looking at a sweet, almost syrupy liquid coming straight from plants. That natural vibe has folks pegging it as an organic alternative to keep things clean in the vaping scene. VG’s known for its three -OH groups making it thick and sweet. Real talk, it’s a great choice if you’re all about big fluffy clouds and that smooth hit (Sanco Industries).
Propylene Glycol (PG):
Here’s the lab-made player in the game. It’s been given the green light from the FDA for being safe, but still, it’s got that synthetic label. PG’s all about the technical vibe—less vapor, more throat hit. It’s what keeps disposable pens and cigalikes ticking, doing more with less thanks to its thinness (Ichor Liquid).
Safety Concerns
| Liquid | From Where | Side Effects |
|---|---|---|
| Vegetable Glycerin | Plant Oils | Dry mouth, sore throat, irritation |
| Propylene Glycol | Lab-made | Same but add headaches, nausea |
Vegetable Glycerin:
VG is as chill as they come for your body, rarely setting off any allergies. Perfect for those who find PG a little bit too much to handle (Pod Salt).
Propylene Glycol:
While the FDA gives PG a thumbs up, it’s not quite as laid-back as VG. It breaks down in your body to lactic acid, which sounds like a boring chemistry class, but it just means PG doesn’t overstress your system. No chance of cancer, messing with your genes, or family growth troubles.
Both VG and PG can be a bit annoying if you’re vaping at high temps. Sore throats and dry mouths lead the complaints, but add headaches and other stuff like chest tightness, especially for the PG fans. Sensitivity plays a role, so know what your body says before diving in too deep (Pod Salt).

Glycerin Characteristics
Getting the hang of vegetable glycerin (VG) is critical for folks dipping their toes into the vaping scene. VG stands out as the go-to for vapers due to its nifty features, setting it apart from its buddy, propylene glycol (PG).
Thickness and Consistency
Picture this: vegetable glycerin being more like a gooey syrup than a runny liquid. It’s this thickness that turns VG into a vapor-making champ. Vapers who love blowing massive clouds are all about VG’s dense vapor production.
| Characteristic | Vegetable Glycerin |
|---|---|
| Consistency | Thick and Gooey |
| Vapor Production | Mega Clouds |
However, this thickness can be a bit of a drag for vaping gadgets. E-liquids with lots of VG take their sweet time soaking into the wicking material, risking those dreaded dry hits if not properly primed. Curious about mastering cloud creation? Check out our cloud chasing guide.
Taste and Price Comparison
VG brings its own sweetness to the table, which jazzes up your vape flavors making them pop. But on the flip side, it could hide those finer flavor notes, so avid flavor chasers might find it a bit overwhelming.
As for your wallet, VG’s usually pricier than PG. That’s because it comes from natural plant oils—think palm or soy. PG, being synthetic, is generally easier on the budget.
| Feature | Vegetable Glycerin | Propylene Glycol |
|---|---|---|
| Taste | Sweet | Plain |
| Price | Pricier | Budget-friendly |

Propylene Glycol Features
Chemical Makeup and Usage
Propylene glycol, often just called PG, is a clever concoction from propylene oxide. If you take a peek at its structure, it sports a couple of -OH groups, earning itself the title of a diol. What you’re looking at is a clear, colorless liquid with a slightly sweet kick. Players from all corners of industry have made PG their go-to buddy. According to Sanco Industries, it’s the Swiss army knife of chemicals, doing jobs like:
- Keeping things moist (humectant)
- Dissolving stuff (solvent)
- Making things last (preservative)
PG’s got a party trick up its sleeve too—it’s chill with the cold, which is why you’ll find it in antifreeze. When it comes to vaping, PG is the hotshot in e-liquid, hanging with vegetable glycerin (VG). Most vape juices have a mix of 80-97% PG and VG. PG knows how to carry flavors and gives vapers that classic “throat hit” similar to a traditional smoke.
Comparing Toxicity to Glycerin
Both PG and its buddy glycerin are pretty safe for us humans, but there’s a bit of difference when you dive into their safety profiles. Glycerin’s the natural charmer in the group, usually coming from plant oils with three -OH groups in tow. It’s all about keeping things smooth and moist, finding its way into foods and skincare products (Sanco Industries).
| Substance | Chemical Composition | Source | Usage | Toxicity |
|---|---|---|---|---|
| Propylene Glycol | Two -OH groups | Synthetic | Humectant, Solvent | Safe overall, but not as safe as glycerin |
| Glycerin | Three -OH groups | Natural/Synthetic | Humectant, Preservative | Non-toxic in its natural state |
PG is seen as generally safe, popping up in low amounts across many products, but it’s got a bit more edge than glycerin. When you blend PG and VG in a vape juice, they put on quite a show. The chemistry lends a sharper, more noticeable experience, plus some extra fog during the exhale (NIH).

Particle Emission Factors
Let’s dive into the nitty-gritty of vaping and what makes those little clouds more or less dirty. We’ve got nicotine and that PG/VG ratio doing a dance that impacts just how many particles get puffed out.
Nicotine’s Role
Nicotine is like the secret sauce in e-liquids, but it can’t keep hiding its effect on particle emissions. A deep dive into some nerdy science (shout out to NCBI for the data) shows us the real score: mix in nicotine with your juice and bam, you’re looking at a 33% drop in particles buzzing around in each puff. In plain numbers, all tested juices put out about 2.5 x 10^7 particles as nicotine gets chummy, and leaves PM2.5 at 113 micrograms per puff. Here’s how the numbers stack up:
| E-liquid Type | PNC (particles/puff) | PM2.5 (μg/puff) |
|---|---|---|
| With Nicotine | 1.7 x 10^7 | 75.71 |
| Nicotine-free | 2.5 x 10^7 | 113 |
Breaking Down Particle Loss
Now, let’s talk about how particles disappear, like your socks in the dryer. The PG/VG mix changes the game again. For vapors skipping the nicotine, boosting the PG/VG level means more particles get lost at sea. But surprise! Bring nicotine back in, and it’s a different story: increased PG/VG ratio actually cuts down on the loss rates.
Check out how it shakes down:
| E-liquid Type | PG/VG Blend | PM2.5 Loss Rate (h−1) | PNC Loss Rate (h−1) |
|---|---|---|---|
| No Nicotine | High PG/VG | 6.0 – 7.0 | 1.0 – 1.2 |
| With Nicotine | High PG/VG | 4.4 – 5.0 | 0.6 – 0.8 |
See, it’s not just about blowing rings anymore; it’s about what gets left behind. So, whether you’re comparing glycerin with glycol or just keeping tabs on the dos and don’ts of vape safety, knowing what’s in that puff keeps it smart.
And for those times when you need to chew over more than just the steam, we’ve got your back with topics like vaping and asthma or vaping for expectant mothers. Keep it informed.
