So I looked around on Reddit and everything about this is old news. I’d like to try it and wanna know if this is safe. I do not see ups anywhere but it is for cosmetics. Be nice with your reply if this is a dumb question… I’m sensitive and some of you are vicious lol…

From the Wiki page:
1,3-Propanediol does not appear to pose a significant hazard via inhalation of either the vapor or a vapor/aerosol mixture.
Yeah I read that. I just wondered if there were differing grades from the processes in which it is made. Correct me if I’m wrong but there are 3 processes. Is this the same as say DuPont TMG?
If Propylene Glycol is PG, would that make Propanediol just P? Maybe it’s just me but I don’t want to vape P.
