esmoke4life,
my apologies for disrupting your post. I'm sure your PG is "perfectly" acceptable. Your comment about 100% (not a big problem, we know nothing is 100%)
U.S. Pharmaceutical Grade is what I was looking for, and the foreign manufacturer (Dekang) for your juice should be trustworthy also.
Thanks, and again sorry about disrupting your post, best of luck with your business.
Tom, one last edit::: I went back to your website, and there is no reference yet to Pharmaceutical Grade with the PG, unless I missed it. Go ahead and brag on your website.
We in the know

have come to judge the source of the PG. This stuff is usually classified as USP, Food Grade, Industrial Grade, and Farm Grade. Typical analysis ranges from 99%, 99.5%, 99.7%. This also helps tell the type of processing and control of the product. Once opened and re-packaged water vapor can be absorbed. This would not be a problem, 5% water added is not what we are concerned with. Unless of course we lose traceability of the original lot and analysis. That would be a problem should the lot (40,000 to 50,000 pounds, or subdivided 55 gal drums) was ever recalled. How would the end user (us) know it a recall affected our stash? If you would like to refer to your product in an industry accepted manner (not 100% pure PG), indicating the original classification. Also indicating that you have on file a COA for the lot, or partial lot that you purchased would be comforting.
Fiend: I am not concerned about trace contamination.
