Propylene Glycol, What is it and where is it found?

Hello! Dawn here, your A Clean Cigarette blogger. Before we get started I want to thank everyone that visits this blog. You are very appreciated! Today we are going to talk about a subject we have talked about a few times before. It’s the main ingredient in the A Clean Cigarette brand e-cigarette, Propylene Glycol.  I always hear questions regarding this ingredient so I thought it would be a good time to do a refresher blog on the subject. If you have more questions about it after this blog and want to look at the other blogs go HERE or HERE.

Propylene Glycol (PG)

What it was created to do and when:

              Propylene  Glycol is a chemical created in the 1940’s by the FDA and  EPA. It was originally intended to clean and disinfect the air in hospitals of viruses and bacteria. In fact, there are human studies from the 1940’s and 50’s proving that  PG is great for combating against contagions such as the common cold and the bacteria that causes strep throat amongst others.

Where it is found:

           Propylene Glycol is considered GRAS by the FDA. Which means Generally Recognized As Safe. It can be found in many         consumer products  including but not limited to this list:

  • Nebulizers: These Asthma treatments and others have been using PG as an inhalable delivery agent since the 1950’s here in America.
  • IV Medications: Due to the overall safety of PG often times IV medications are used with PG. The PG acts as a delivery agent.
  • Eye Drops: Again PG is used here as an ideal delivery agent due to its overall safety record.
  • Foods: PG is used as a preservative for many foods such as some Little Debbie’s, nearly all packaged muffins and many more food products.
  • Personal Hygiene Items: Such as shampoos, conditioners, toothpaste and other topical products.

From the list above we can tell that PG is considered safe for most uses. Including topical, inhalation, intravenous and ingestion. It’s even safe to be used in eye care, which is a pretty sensitive area of the human body.

Where it is  NOT found:

           Original Antifreeze:  When original anti-freeze started to kill our pets people got upset. So the smart folks in the Anti-freeze business created a PET SAFE Anti-Freeze. In order to make their product non-toxic, they needed a safe to use ingredient. They chose PG for its GRAS certification. As a general rule, PG is ONLY found in non-toxic Antifreeze .although do to its -70 freeze point it is used in many types of anti-freeze and ice melts. Be sure to read all labels on any products you purchase.



So there it is, the basic 411 about Propylene Glycol. Like every chemical, even water has a point where it starts to do us harm. PG is no different. It’s not fresh clean air so it is not good for you. But remember what we compare ourselves to. The traditional burning tobacco cigarette. The TAR alone in those things kills hundreds of thousands of people each year. If you are interested in REALLY diving deep into PG then I suggest This research paper. The number of studies, sources, and information available there is spectacular.

If you or a loved one has not made the switch and you are thinking about it but were not sure about PG, I sure hope this blog helped. Visit for more information. If you have already made the switch but have friends and loved ones who give you grief about what is in your e-cigarette. Then I hope this helps as well.  Please feel free to reach out to me with any doubters doubts. I will do my best to find answers and get you the sources you need.

Thanks again for stopping in!



PS: FYI: Keep in mind that most Brands of burning tobacco cigarettes also contain PG. The use it to control the moisture content of the tobacco. There are no NEW ingredients going into your lungs when you switch from burning tobacco to A Clean Cigarette brand e-cigarette. There are however about 600 fewer ingredients in our product compared with burning tobacco cigarette products!
