VG FER REAL

There's not a single animal-based USP glycerin on the market. Not one. Nor would it be financially feasible to do so. The vast majority of the glycerin on the market is NOT USP and comes from soy as a byproduct of biofuels. USP represents a very small part of the market. USP is pharmaceutical grade, which is the same (in this instance) as food grade (FCC -- Food Chemicals Codex). Humco is the main supplier, with over 75% of the single-product USP market segment. Proctor & Gamble uses most of their USP Glycerin in-house, in products like toothpaste and make-up. They have a Kosher-certified product as it's popular in make-up. All Kosher certification means is that they have spent the money to have rabbinical sign-off of their processes and handling. The product itself isn't different. P&G does sell some of their Glycerin to the market. To be USP it cannot be referred to as "Vegetable Glycerin", only "Glycerin" as that is the correct name (monograph). And the USP standard is 99.0%, but to also be labeled Anhydrous (not containing water) the threshold is 99.5%. The FDA and USP have agreed that to be wear the USP monograph, the Glycerin must contain no more than 0.10% Diethylene Glycol (DEG) or Ethylene Glycol (EG). Since this is the "poison" of inhaling VG, as vapers we want to avoid them, and thus we want the USP certification. But whether the label reads 99.5% or 99.7% or 99.999999999999% is immaterial as it essentially means that their reference samples were *at least* their label. So it might say 99.5% and test this batch at 99.9999%..... we live in a litigious society, it's a CYA cover-your-ass thing.

So if you see "USP" it was made by Humco or P&G. They make private brands in-house where they are properly handled and bottled. And some other morons buy in bulk and pour smaller amounts into bottles and label it themselves and still sell it to you as "USP" which is *IS NOT*, or at least is no longer. The moment that bottle breaks the seal, it cannot wear the USP label. Yet it is common practice. Unless it is done in a humidity controlled clean-room under nitrogen bath, VG will quickly (immediately) absorb water as it is a strong hygroscopic humectant.

Will anyone read this? Maybe. Will we get the same question tomorrow? YES. Will someone enter the debate and spew bullshit about animal fats and better qualities available (neither are true)? YES. It gets really, really old.
