Did I by the right glycerin?

[bfitz]

Hello all,

I was out and about today and saw at my local drug store a bottle of "first aid glycerin skin protectant". Below that it reads glycerin anhydrous USP 99.5%. I am just getting into diy and didn't have any way to check and see if this could be used as vg in juice , but I have dry skin anyway so if it is wrong at least it isn't a waste. I remember reading that glycerin could be bought locally but am not sure if I got the right stuff, just wanted to ask before I try it.

Thanks

Says USP= good to go.

Cool, thank you hubseven. After double checking what I had read I was pretty sure but I wanted to find the stuff from Walmart that I see a lot of people using. The one by me is remodeling and has a lot of stock removed so I though I would try this.

You can get a gallon of VG AND a gallon of PG for $40 total from http://www.essentialdepot.com/servlet/the-218/1-Gallon-Veg-Glycerin/Detail

I'd be a bit concerned about what that other .5% is.

It's also probably not VG, but synthetic glycerine, if that makes a difference to you.

I would assume its mostly water. By definition.

Correct, the .5% is moisture.

there are only a few companies that make vg, much like pg, chances are it is either from dow or humco(only other companies that i know of are health food ones like NOW). ive been getting my vg at wal-mart forever it says natural on the bottle and is usp. so unless you are getting your vg at a health food store you are getting it from one of those two companies repackaged

You need to be careful. USP specs on glycerin is 99.7% minimum for food use, not 99.5%. It is a standard specification worldwide. 99.5% is a technical grade specification for glycerin. Sounds like an import product.

Glycerin that is 99.5% can be USP. I use the CVS and Rite Aid Glycerin USP all the time; they are both Humco relabels.

Read post 42 here: http://www.e-cigarette-forum.com/fo...ble-glycerin-vs-humco-glycerin-warning-5.html
"...All OTC glycerine,USP is made by 1 single manufacturer, HUMCO. It is then contract packaged into the different pharmacy labeled bottles. I've personally called HUMCO and spoke with their QA(quality assurance) person. He assured me that HUMCO's Glycerine is in fact Vegetable source Glycerine. The reason it's labeled Glycerine and not Vegetable Glycerine is because #1 it is listed in the USP as Glycerine, USP and therefore(in order to keep the USP certification) must be labeled as it's listed in the USP. #2 it would cause confusion as Glycerine is Glycerine(regardless of the source - chemically 1,2,3-propane triol), to add the moniker VEGETABLE, makes it sound like it's two different and distinct products, it isn't. Also, USP grade Glycerine is the purest you can get. Food Grade "vegetable Glycerine" you get in health food store saying 99.9% is BS...."

 

[flintlock62]

That's not actually correct. 99.5% USP glycerin contains 0.5% moisture. If it's Kosher grade, then it has an even more strict certification. Don't purchase glycerin that does not have the Kosher certification.

I found out I was really alergic to anhydrous on my hands. Industrial Isoprophl Alcohol has it in it. I cut my juice with Glycerin sometimes.

I take the writeup on pg/vg labeling and purity, a sticky in this subforum, as being an authoritative reference.

Based on it, I care about USP (or EP, in Europe), but kosher certified doesn't mean much (fine to have, just that the USP or EP are the critical purity designators).

Actually, Kosher certification does have importance. I won't go into the details, but "Kosher" certification is more stringent.

You should provide a forum moderator any corrections to the kosher description in that sticky. I haven't seen anything that tells me why/how kosher is relevant, certainly nothing that tells me that it establishes percents, limits contaminants, etc. (which usp does do); a chance to learn is good
