My go-to response for the pg statement is that it's been the propellant for asthma inhalers since the 50s...that usually shuts them up.
Just think: This poor ....... is probably married and his wife has to put up with his BS every day and twice on Sundays.
Unless she wised up and hooked up with a Vaper.

I've only had one person say that anti-freeze line to me. I simply responded that it is a perfectly safe product that all pharmacists use for compounding many ingested medications.
If someone gave me that line now, I would probably ask if they enjoyed the chemical solvents they ingest. When they give me the confused look, I would point out that the beer or wine that they enjoy has alcohol and dihydrogen monoxide in it and that both are powerful solvents.
Dihydrogen monoxide is more commonly known as water.
Just because it sounds like a scary chemical, it does not mean it is.

You can add to your list that antifreeze is given to babies and children every day by their own parents! It's in their medications.
Maybe these people don't realize that when they're having their beer or wine, they're drinking antifreeze? Goodness gracious me!!! 
I was going to say the exact same thing!
When I first heard propylene glycol, the first thing I thought was antifreeze. However, with the light amount of automotive experience I have, I did remember that it was ethylene glycol in the "pet killer " antifreeze. Knowledge is power, and on our cases, vapor-able.

here is the poison part:
Poisoning[edit source | editbeta]
Main article: Ethylene glycol poisoning
Ethylene glycol is poisonous to humans and other animals,[3][4] and should be handled carefully and disposed of properly. Its sweet taste can lead to accidental ingestion or allow its deliberate use as a murder weapon.[5][6][7] Ethylene glycol is difficult to detect in the body, and causes symptomsincluding intoxication, severe ........, and vomitingthat can be confused with other illnesses or diseases.[3][7] Its metabolism produces calcium oxalate, which crystallizes in the brain, heart, lungs, and kidneys, damaging them; depending on the level of exposure, accumulation of the poison in the body can last weeks or months before causing death, but death by acute kidney failure can result within 72 hours if the individual does not receive appropriate medical treatment for the poisoning.[3] Some ethylene glycol antifreeze mixtures contain an embittering agent, such as denatonium, to discourage accidental or deliberate consumption.
here is the pg part:
Propylene glycol[edit source | editbeta]
Propylene glycol
Propylene glycol, on the other hand, is considerably less toxic than ethylene glycol and may be labeled as "non-toxic antifreeze". It is used as antifreeze where ethylene glycol would be inappropriate, such as in food-processing systems or in water pipes in homes where incidental ingestion may be possible. As confirmation of its relative non-toxicity, the FDA allows propylene glycol to be added to a large number of processed foods, including ice cream, frozen custard, and baked goods.
Propylene glycol oxidizes when exposed to air and heat, forming lactic acid.[8][9] If not properly inhibited, this fluid can be very corrosive,[citation needed] so pH buffering agents are often added to propylene glycol, to prevent acidic corrosion of metal components.
Besides cooling system corrosion, biological fouling also occurs. Once bacterial slime starts to grow, the corrosion rate of the system increases. Maintenance of systems using glycol solution includes regular monitoring of freeze protection, pH, specific gravity, inhibitor level, color, and biological contamination. Propylene glycol should be replaced when it turns a reddish color.[10]

Fake blueberries are made from pg. Most blueberry muffins do not contain blueberries at all. They're flavored blue pellets of pg and sugar. True story....
awesome thread.... I found this and thought it was interesting...
Science Dictionary
propylene glycol:
A colorless, viscous liquid used in antifreeze solutions, in hydraulic fluids, and as a solvent. Unlike ethylene glycol, it is not toxic and is also used in foods, cosmetics, and oral hygiene products. Chemical formula: C 3 H 8 O 2 .

In just about any company I've worked for there is always at least one person like this lol. You have to be firm with them from the start. It's almost to the point of bullying and these people are usually trying to get very close to the boss as well. I tend to be friendly with them so they leave me alone and choose another target.
Secretly I do despise them. If you don't give them what they need, they usually move on.

Don't start with the political BS please, it will just turn into a bitter your side is worse than my side debate.
Very informative thread. My biggest question had been, although we know that many of the products we use everyday contain PG and we know how it reacts when ingested/put on skin/etc., how does it react when inhaled? I then saw previous posts that stated PG has been used as inhaler propellant and is used in hospital ventilation systems to combat airborne diseases. To me, those are the most salient examples of PG use. Comparing apples to apples, if you will.
