I think I looked at that online once and they said it was USP-but there is no USP cert. for 'vegetable glycerin' just 'glycerin.'
http://www.usp.org/ You can poke around USP's huge site if you're interested in what exactly that means.
I saved a long ass rant some guy posted on one of the FB groups about glycerin if anyone's interested in some explanations about USP and glycerin:

(Can't go wrong with Humco glycerin from Wal-Mart if you're not ordering in bulk.)
Not only can you vape it, the inside of your throat will look 10 years younger!
Just kidding! No unless it's got USP on it, i wouldn't.
I'm using non-USP grade Wilton glycerin from Michael's, used in baking, and it seems to work fine.
USP just means that it meets a certain set of pharmaceutical standards, but the food-grade glycerin is really close in quality.
I haven't noticed any adverse effects anyway, and according to a lot of searching around the web, the majority of the glycerin on the market comes from the same manufacturer anyway.
Hi. Thanks for helping me out really appreciate you guys and this sub.
Also curious if this glycerin is ok to use? Not sure what I'm really looking for http://i.imgur.com/xyy3pSy.jpg
Yeah, this one is fine, see my other post here.
Are you talking about the picture in my comment the usp glycerin? I hope so. It's way cheaper haha.
Where about sis this post I can check out?
what youre looking for is "USP" that means it came from US pharmaceutical supply
I've used NOW glycerin for years; as far as I'm concerned it's pretty close to as good as it gets for DIY and is significantly better than the rebranded Humco glycerin you get at the big box drugstores.
NOW foods confirmed some time ago that their glycerin is USP and some of us think the reason they don't carry the logo is a marketing decision. Will see if I can find the thread.
edit: found it. Here's the thread -

I don't see a USP mark on it. Skip it and get something else.
The other telling sign is that nothing like this is 100% pure, so that's just false advertising. USP grade, which is as pure as we can get, is 99.5% pure, and labeled as such.
Always look for "Glycerine, USP" as the name of the product.
I was 99.9% sure that there also exist 99.7% pure USP grade glycerine as well.
Yeah, you occasionally see that. I haven't turned up the monograph for it, but I haven't really gone looking for it either. The 99.5% we most commonly see can be interpreted as "at least 99.5%, but we're covering our ass by putting this standard purity on it". This is the main reason that anything labeled as 100% pure is kind of sketchy. Usually it's deceptive, their "meaning" is that they haven't added anything else to the product, but that doesn't mean the product is chemically pure.
Remember someone saying a long time ago that it was usp, although I haven't seen that myself. It does say food grade, if that means anything.
But, other USP labeled VG has irritated me, and this one doesn't, so this is the one I use.
I'm completely okay with stuff at this point not being USP grade. The differences between vegetable sourced and animal sourced glycerine are there, regardless of the refining process. Anything that's basically Humco tastes like an awful, harsh mess. I can taste Humco a mile away (which is animal sourced). Vegetable sourced glycerine on the other hand has proven much more smooth. I myself just purchased a bottle of this Now stuff and I'm hoping it's as good as people have said. If it tastes cleaner and less harsh, I don't care if it's USP grade.
USP = United States Pharmacopeia
Generally, we see USP 99.9%. I have yet to see USP 100% pure in Glyceryn. So when the product shows 100%.. It's not USP. I would like to see lab/food grade 100% Glyceryn as an example. There is humidity in our atmoshphere.. So I think it would be impossbile.
personally i would not vape anything meant for skin care; look online and order from a vape vendor.
PG and VG are used in TONS of everyday products! I understand that if you haven't really researched what the ingredients are that you're inhaling, just play it safe and get it from a vape source.. But don't say you wouldn't vape it because its used in something else, if that were the case, you wouldn't be vaping! lol Next time you put deodorant on, look at the ingredients.. Propylene Glycol! lol Sorry, i'm not trying to sound like an ass, just trying to help educate and share some interesting info..
