The symptoms of being Propylene Glycol intolerant

Posted by Just Vape 247 on 12th Mar 2022

Before we discuss the symptoms of a Propylene Glycol allergy/intolerance, what actually is Propylene Glycol?

Propylene Glycol (sometimes referred to Monopropylene Glycol or Methyl Ethyl Glycolis) is a synthetic food additive that belongs to the same chemical group as alcohol. It's a colourless and odourless liquid.

Propylene Glycol is used in a range of industries from cosmetics and pharmaceuticals to agriculture, food and of course the vaping industry. 


Propylene Glycol isn't the only component of an e-liquid, you can read more about the others here. However almost 100% of the e-liquids sold today contain Propylene Glycol. It is used in e-liquids because it’s an ideal carrier and the fact is it flavourless allows the actual e-liquid flavour to shine through.


The symptoms of a Propylene Glycol allergy:

  • Skin Rash
  • Headache/Migraine
  • Sore/Dry Throat
  • Cough
  • Tingling or burning sensation felt in the sinuses

What is important to note is that you can become Propylene Glycol intolerant even if you have previously vaped Propylene Glycol for a while or in the past without any issues. An allergy may develop out of the blue. 


So maybe you have already Googled such questions as "why do I have a headache after vaping?" or "my throat is sore from vaping?". Now you are left wondering what to do next. Don't worry you are not alone, one option of course is to stop vaping but if this isn't an option for you and want to continue to vape then you will be relieved you stumbled on this blog...

To mix your own Propylene Glycol free e-liquids you will need to use Vegetable Glycerine as your carrier liquid instead of Propylene Glycol but don't forget your flavours and nicotine will need to be Vegetable Glycerine based too.

The key differences between mixing e-liquids that contain Propylene Glycol and ones that don't is that Propylene Glycol is a better flavour carrier that Vegetable Glycerine.

This means you may mix your e-liquids with around 10%-15% of flavour currently, you may need to up this amount to around 20%-25%. 

The other key difference is the consistency of the liquid. Without Propylene Glycol, the e-liquid will be gloppy as Vegetable Glycerine is thicker than Propylene Glycol. 

To prevent your coils on your e-cigarette device from clogging up we highly recommend adding 1-2% of distilled water to your e-liquid or alternatively use Aqueous Glycerine (Vegetable Glycerine pre-mixed with distilled water) as your carrier base.

Remember that you may or may not have an allergy, there are other reasons why you may experiencing these symptoms. For example headaches are possible if you are vaping a too high nicotine strength or consuming too much nicotine.

Your e-liquid also could be the incorrect Propylene Glycol to Vegetable Glycerine ratio for your tank. Some e-cigarette vape devices require a lower Propylene Glycol percentage e-liquid as they are designed to create more vapour (or clouds). If you vape a high Propylene Glycol e-liquid in these type of tanks, this could lead to a very sore throat.

We always recommend to stop vaping and seek professional medical advice if you are worried or concerned by any symptoms associated with vaping.
