I'm very interested to see how this turns out / if by some miracle we organize a group buy.

I have CoA's from Norfox and stat sheets that say it's 99.9% pure. You don't have to go on some super quest to get "the best" pg and vg. They are right down the street from us. You should check out chemical manufacturers in your area, and request some samples. I wouldn't suggest doing that though, if you only plan to order 1 gallon or less. There are also independant labs that can test your product. Why not use bulk apothecary if the tests say it's good? Just things to think about.

Pharma is anti-vaping/tobacco. I think you may have trouble getting it directly.

Someone tried in 2013: > P&G Chemicals maintains our position that we will not supply any of our glycerin brands to the tobacco industry. This includes all Superol, Moon OU, and Star grade glycerin products in North America and Asia. > P&G Chemicals made the decision to exit its business with the tobacco industry in 1995 and has since upheld the decision. Our position remains consistent with P&G’s commitment to Health Care.

I am interested in getting the best VG available also. Does anyone know the advantages of Palm-Free, or Soy-Free types?

I am getting 5 liters of Danish made 99.5% next week. Supplier only says it is created in Denmark by pharma so I guess it can't be that hard to find out who does it.... It is the best quality stuff I have found so far and quite a lot of the vape shops online I have bought VG from previously, mostly always has 15% water or something.

Don't forget Sigma-Aldrich too.

Not sure how accurate this quote is, but I read this off of Bulk Apothecary:
"Since glycerin is a waste byproduct of biodiesel production, the market has recently been depressed. In fact, there is only one producer left in the USA for high quality glycerin production. Sensitive pharmaceuticals are the only current market for this product."

Do you know which amazon sellers get from ADM?

Hey /u/JustSayNoToDiacetyl

I get my VG from Wizard Labs. http://wizardlabs.us/index.php?route=product/product&path=83_70&product_id=625

Here is the MSDS http://wizardlabs.us/image/data/msds/MSDS_Vegetable_Glycerin_USP_Wizard_Labs.pdf

I have written to the staff requesting more information regarding the manufacturer of the VG. Will let you know what I hear back.

Also, I found your username funny. I keep hearing worrisome things about Acetoin. And then some long time community member comes around and says how its not a big deal, and that Diacetyl very rarely results from acetoin, and even when it does it is trace amounts... Etc. What are your thoughts?

I believe most of what we get is Humco if I'm not mistaken?

Edit: It's a question. Don't be a dumb fuck and downvote questions.

I've been doing sleuthing the past few days in search of the best VG. I came across a site named "Chemworld" that sells 99.7 USP VG. In their description they claim it is manufactured in the USA."

However, a simple perusal of the COA's they have posted to their website clearly shows it as having been shipped by a cargo vessel. This means, obviously, it was shipped internationally.

One of the COA sheets mentions that it is a glycerine with the trade name "Wilfarin." A google search confirms that Wilfarin is a trademark registered to a company called Wilmar International. A simple perusal of that company's website shows clearly that they are headquartered in Singapore.

Moreover, the ChemWorld website says their glycerine is Soy based, but my research (i.e. my google skillz) shows that "Wilfarin" is actually palm based. (It is possible that Wilmar produces glycerine from various sources, so I am not going to harp on this).

So, what's my point? There are a lot of vendors out there who are telling tall tales when it comes to Glycerine probably to avoid the "made in China" stigma.

Now, does this mean that their Glycerine is impure or "tainted" in some way? No. It is probably just fine. The test results seem to indicate this and the Glycerine does appear to conform to all USP standards. Just because something is foreign made doesn't mean it is of low quality. However, for me personally, I would rather buy U.S. sourced (that means MADE here) glycerine if I am going to be inhaling it. But that's just me.

A few years ago there was a scandal in the glycerine industry where some international companies were labeling DEG as glycerine and selling it as glycerine. This caused numerous deaths (mostly in third world countries). The FDA responded and asked the USP to update and tighten the specifications for glycerine. Now there are specific tests for DEG and EG that all USP glycerine must pass.

In any case, I give Chemworld 7 pinocchios on this one. I wont be buying from them. If you sell Asian sourced Glycerine, just be honest about it. Again, it might be just as high quality as U.S. sourced glycerine, but let the consumer make the decision.

Important Edit:

I contacted Chemworld after I wrote this. They informed me that they do sell imported Glycerine but it is clearly marked as such. The rest is USA sourced. They have about a dozen different COA's on their site (for different batches) and it can be rather confusing. In any case, it is USA sourced as long as you buy the product advertised as USA sourced. I asked where it was sourced and they just said "we have different manufacturers." In that case, I presume it is one of the manufacturers listed in my original post (likely ADM or Cargill). He did say they do not carry Dow Optim.

I am still on the search for P&G's Superol or Dow's Optim. Both are nearly impossible to find. I presume because both companies keep strict control over their distributors. I do know that both companies will not do business with anything tobacco related and both have, unfortunately, lumped vaping in with "tobacco."

Crap, I'm a vegetarian and didn't think to check vaping related stuff.
