|  NASA is planning to use PG-based coolant for the Orion crew exploration vehicle.
If this has been posted already [Tried tagged search] then feel free to delete. Kamanjah over at Right to Vape found this document on NASA's look at using Propylene Glycol as a coolent and their investigations into it's toxicology. Spacecraft Maximum Allowable Concentrations for Selected Airborne Contaminants: Volume 5 Pretty interesting read, or the bits i could understand were.

Thank you, Mungo! It does have some very interesting info on PG. I skimmed the info now, but due to the large amount of info I need to really read it very slowly later today. And, thank you Kamanjah at Right to Vape

I wasn't sure where to post it here! I found another interesting tidbit - Rhinaris Nasal Spray is totally PG only and is OTC in at least the US and Canada. More info here. Am going to post that over in the Health section too.

I didn't find that site when I was looking. I checked about 5 links I found on google, mainly trying to find out if it was FDA approved. But when I clicked on the gel link, it said "Rhinaris nasal gel is a drug-free solution that helps to restore moisture to soothe dry and irritated nasal passages. The gel quickly absorbs into the skin around the nostril area, leaving little residue or trace of application. It contains the lowest concentration of saline (0.2%) that will not dry out your nose over prolonged use. The unique formula is non-greasy, odorless, colorless, water based and contains two glycols for added moisturizing relief. Rhinaris Gel is available over-the-counter, without a prescription." And that's what they recommend for infants. Weird, doesn't say which glycols. So much to learn!
