Some chemicals life Propylene Glycol have scary names but should you be afraid of them? PG sounds scary when you first hear the term but the reality is there are many chemicals with scary sounding names around us, should you be afraid of all of them? This article will examine the safety of PG in vape juice.

Propylene Glycol (PG) is a synthetic liquid substance that is used by the food and pharmaceutical manufacturers. The FDA has classified Propylene Glycol (PG) as an additive that is “generally recognized as safe” for use in food. Many e-juice manufacturers use Propylene Glycol (PG) in their vape juice because it produces vapor when heated.

PG is used in many items around us so even if you don’t vape, you’ve probably come into contact with PG because it’s used in everything from foods, pharmaceuticals, cosmetics to anti-freeze.

PG is technically an alcohol that’s colorless, odorless, and clear. As mentioned, the FDA states that it’s “generally considered as safe” for use in foods and many household items. Here are some examples of things that contain Propylene Glycol (PG): Iced Tea, toothpaste, salad dressings, cake frosting, and even some brands of ice cream.

PG is great because it’s a great solvent (you can dissolve things in it) and it has a low toxicity rate make it great for use in many products including electronic cigarettes and vapor products.

Is Propylene Glycol Safe for Use in Vape Juice?

We know that Propylene Glycol (PG) is safe for human consumption as in foods, but is Propylene Glycol (PG) safe when inhaled? The answered depends on who you ask. PG can cause some damage to the lungs, but the harm done is at least 95% less than the harm caused by smoking tobacco cigarettes.

ASPET Journals conducted a study in 1947 that concluded that PG (Propylene Glycol) was “completely harmless” when tested on animals who inhaled it. In the experiment animals were kept in Propylene Glycol infused air, later the animals were dissected and the researchers conducted extensive research to determine the effects of PG on the bodies.

The researchers found that the animals that were exposed to Propylene Glycol air for months at time were completely normal: their kidneys, liver, spleen, and bone marrow were normal.

Propylene Glycol Side Effects

Some vapers have experienced side effects from using PG (Propylene Glycol) vape juice that lasted for a few days until their body got used to the PG that was in their vape juice.

If you’re someone who has allergies to PG you should drink plenty of water because PG tends to attract water causing you dehydration, so please stay hydrated and drink plenty of water while vaping as most e-juices contain some amount of PG.

If your allergy to PG is not going away you might want to consider using MAX VG vape juices. These are vape juices that have a high amount of VG and very little PG. This should help with any minor allergies you’re having. We will list some vape juice brands below that have 70VG / 30PG blend. These blends have little PG compared to other e-juices which can be 30VG / 70VG blends. If you’re having more serious allergies please contact a licensed physician.

Also, make sure that you’re not mistaking cigarette withdrawal with a PG allergy. When people quit smoking they tend to suffer from the following side effects:

  • Headache
  • Nausea
  • Stomach Pain
  • Difficulty Concentrating
  • Difficulty Sleeping
  • Constipation

Minor Propylene Glycol Side Effects include:

  • Mild itchiness and skin irritation have been reported
  • Mild allergic reaction
  • Sore throat
  • Dehydration (Always drink plenty of water while vaping)
  • Eczema

Please remember, while you’re vaping always drink plenty of water especially when you first start. Drinking water may take care of many of the symptoms you may be experiencing from vaping.

Propylene Glycol Conclusion

Due to the abundance of Propylene Glycol in vapor products, we understand that vapers are concerned about the safety of this substance. Rest assured that both the FDA (Food and Drug Administration) and the WHO (World Health Organization) consider Propylene Glycol (PG) as safe to use.

Vaporizers have been proven to carry a fraction of the health risks that are associated with smoking traditional cigarettes due to the low amount of toxins and carcinogens that are present in electronic cigarette vapor when compared to cigarette smoke.

So, if you’re someone who is considering purchasing a vape setup but have a minor allergy to Propylene Glycol (PG) try choosing a vape juice from the popular brands that we listed above as they are mostly VG (Vegetable Glycerin) which reduces the problems you will have while vaping.
