Anhydrous glycerine???

[Zelphie]

Is the glycerine you can buy from any store such as rite aid or walmart (which is anhydrous glycerine 99.5% usp) the same TYPE of glycerine used in eliquid?

Is this the natural or synthetic form?

Its hard to tell cause different vendors call it different things such as aqueous glycerine, vegetable glyerine, or glycerol.

 

[leannebug]

I'm not quite sure. They say it's the same thing. However I have used the stuff from the drugstore, skin protectant, and also from Wiltons, vegatable. To ME, the wiltons tasted better. YMMV.

Anhydrous means no water.

So what you have has a precentage of water at 5%.

DVap said:

I believe when you see 99.5 % anhydrous glycerin on the label, you're looking at an assay. The product is 100% in everything present (glycerin and water), but when tested, the product is tested for anhydrous glycerin, and that assay comes out to 99.5%, the other 0.5% is water.

To look at it another way, say there was a USP grade glycerin at 50%. The label would say "Active Ingredient: glycerin anhydrous 50%". The inactive ingredient would be water 50%. The overall mix would not be anhydrous.

So when you buy USP glycerin anhydrous 99.5%, you are not buying anhydrous glycerin. You are buying 99.5% glycerin and 0.5% water.

Aqueous glycerine also has water content. Totally Wicked sells it and says on their website:

Our aqueous glycerine is a blend of glycerine USP and just enough deionised water to thin it to the perfect consistency for vaping.

Vegetable Glycerine is an oleo chemical made from vegetable fat.

Vegetable glycerine is 100% vegetable made. Glycerol is just another name for it as is glycerine

 

[DVap]

honestly, I think the whole anhydrous glycerin thing is rather confusing... and I had to presume that the stuff I wrote in the above post is the case. Nothing else makes any sense.

 

[leannebug]

So then- would anhydrous glycerine be vegetable glycerine with 5% water? (and the aqueous = veg + %> ?)

Basically: is the base still the same? (all vegetable) Or is it compounded? Or something else entirely?

 

[smokum]

Any USP tagged glycerin I've come across I would go to their website (or contact them) to find out what it is derived from.

To date, every single "USP" tagged one has turned out to be vegetable derived with the only difference being WHICH vegetable they used (personally I didn't care because I have no sensitivities to "any" vegetables, or foods, to worry about it).

Unfortunately, I haven't logged my findings as I came across them, but surely would have alerted others if I had actaully come across one that was "animal" fat derived (which I havn't found under the USP tagged ones), that are for External Use Only when related to lotions.

I use the PG Rite Aid sells and have not found a bit of difference when it comes to home-brewed juice.

 

[leannebug]

ew... animal fat Don't think I'd want to vape that. Just something about it turns my stomach.

Glycerin comes from soap. When soap is 1st made it has some glycerin in it. With the store bought soap what they do is remove the glycerin from the soap because it is valuable for things like lotion. (its very good for your skin) Vegetable glycerin just means they used vegetable fat to make the soap. If they used any animal fat, like lard, (nothing wrong with lard soap BTW) then it would be glycerin. If you are vegan and live a completely animal free lifestyle then you would want to make sure you get vegetable glycerin. If you live a lifestyle that goes according to Kosher law's then you may want to find on line suppliers that sell Kosher glycerin.

Otherwise your main concern is USP, this speaks to the purity of the glycerin. Look on the label for 99.5% USP glycerin.

I see this kind of question every once in a while. I'm wondering if someone who's better at explaining things could make a sticky on this subject. (Unless there is one already, and I missed it)

Glycerin doesn't come from soap, soap is often made from glycerin. The transestrifacation of lipid(fat) separates the glycerin from the esters. The esters are often used as biodiesel these days, there were other uses previously. The glycerin can then be refined and used to make soap. Soap is not a naturally occuring product, the fat is. And AFAIK all USP glycerin MUST be made from veggies, no animal fat.

Bolding mine so I can understand better

I'm not trying to start a fight, your right the fat contains the glycerin. But soap is made from fat + NaOH not glycerin + NaOH. You can then take the glycerin out.

Or am I misunderstanding what you're saying.

Transestrifacation uses lye and methanol(usually) to sepparate the glycerin from the fat. The lye then stays IN the glycerin. This is how lye soap used to be made. Now, it is common for the lye to be removed, as people don't use lye soap any more. Currently, the process is mostly done to make biodiesl. But also to make glycerin.

I'm sorry I'm lost by your use of the word glycerin. If I take olive oil and add the correct amount of lye I've made soap. I don't know what would happen if I took gycerin from the store with the lye. I don't think the lye ever goes anywhere, if you look at the label on a hard bar of soap you'll see sodium palmate, which is the lye and the palm oil, Sodium cocoate is the coconut oil. As far as I know the only way to make a hard bar soap is with lye, it's a salt or so I thought.

You are likely to also see glycerin on that list of ingredients, which means that the lye(base) was added to glycerin. Glycerin does not come from soap.

From Florida Syn Gas:

Glycerol: has several names such as glycerin, glycerine, propane-1,2,3-triol, glyceritol and others. It should NOT be confused with Glycol. Glycerol is a sweet tasting, odorless, colorless and viscous liquid that appears similar to Karo syrup. The molecular formula is C3H8O3. Glycerol is created in several way in industry, but the most important method recently is as a by product of the transesterification process. This is the process that creates bio-diesel fuel.

Transesterification: A chemical reaction which occurs when one mixes vegetable or other plant oil (bio-oil) with an alcohol (like methanol) and adds a catalyst to promote the reaction to occur. The reaction's resultant compounds are bio-diesel fuel and waste glycerol.

Commonly, when people made homemade soap, lye was added to fat to make soap. This is not being done anymore(for the most part), because it is not an efficient way to mass produce soap. Glycerin does not come from soap. Transestrifacation is the most common way glycerin and esters(biodiesl) THESE DAYS are separated. Yes, you can make soap by just adding lye, and usually alcohol, to any fat. That does not mean that glycerin comes from soap.

More information from Answers.com:

History of biolipid transesterification
One of the first uses of transesterified vegetable oil (biodiesel) was to power heavy-duty vehicles in South Africa before World War II. The name "biodiesel" has been given to transesterified vegetable oil to describe its use as a diesel fuel.

It was patented in the U.S. in the 1950s by Colgate, though biolipid transesterification may have been discovered much earlier. In the 1940s, researchers were looking for a method to more readily produce glycerine, which was used to produce explosives for World War II. Many of the methods used today by producers and homebrewers have their origin in the original 1940s research.

Biolipid transesterification has also been recently shown by Japanese researchers to be possible using a super-critical methanol methodology, whereby high temperature, high-pressure vessels are used to physically catalyze the biolipid/methanol reaction into fatty-acid methyl esters.

I did contact Humco, and they did say it was indeed vegetable based, but what veg. I didnt even think to ask...

 

[Dakota]

So If I understand correctly, most/all USP glycerin is NOT synthetic? I've had a HECK of a time finding a store with glycerin at ALL, let only VEGETABLE glycerine. And no one has propylene glycol (at least around here). i get funny looks when i ask for it.

 

[Bageone]

CVS pharmacy in Cali carries glycerin and also most health food stores carry vegetable glycerin but it will be more expensive. The Perfumers Apprentice sells VG and PG, order some when you order your flavors

 

[leannebug]

Humco was the first brand I purchased. It has been noted (on the forums) that it is safe to use. I believe someone contacted Humco and asked questions in great length. Personally, I did not care for it... some do.
Humco is also much easier to find. Walmart, Walgreens, CVS drugstore (to name a few) may carry it already in the pharmacy section. All you need do is ask at the counter, ask for it by the FULL name, and when/if they say they don't carry it, ask for someone else If they don't have it in stock, they can order it for you (esp the VG) IF they are nosy, and want to know why you need it, tell them you want to make soap Or as another is want to say: tell them you are having an adult party and want to make KY THAT will stop all questions (I'd go with soap, but I'm a chicken)

Now I prefer the Wilton's brand of VG. Hobby Lobby carries it in the candy making aisle, along with the Loranns flavorings. I've heard that some Walmarts carry it, as do other hobby stores or even cake stores (bakeries). I prefer this brand because of the taste, so it's possible that it is made with a different vegetable (or maybe the fact that Humco brand says "skin protectant", even tho it's a veggie glycerin, may have tainted my perceptions.)

So If I understand correctly, most/all USP glycerin is NOT synthetic? I've had a HECK of a time finding a store with glycerin at ALL, let only VEGETABLE glycerine. And no one has propylene glycol (at least around here). i get funny looks when i ask for it.

(see above for ideas ^^ on where to find VG) PG is carried at a place called Tractor Supply. I did not think we had one around here, but recently discovered otherwise. If you live anywhere near/close to a farming community, I would try there.

It would not make one bit of difference where the original base of came from. If it is certified USP, then you should be safe

You could, theoretically, start out with petroleum or natural gas out of the well or fat from a pig, and end up with propelyne glycol and glycerin. In fact, you could even do it practically; it's just not cost effective. The ability to crack, distill, combine, change things around is one of the wonders of carbon based chemistry.

Synthetic or not only means something if you have concerns about the origins of your product, e.g. if you have certain religious dietary laws that you must observe.

Chemically, it makes no difference in the end product. Regardless of the source, the same two chemical compounds from different sources will be the same, IF they are certified to the same level of purity. Sometimes, it can be a big IF.

Anhydrous should not really make much difference. There are a lot of compounds that have water in them, either as a result of the chemistry or because they are very hydroscopic, meaning they suck up moisture very quickly. Ethyl alcohol (the stuff in booze from beer to wine to vodka)is a good example: it will absord moisture very quickly.

You have to go through a lot of trouble to get all of the water out. Unless there are compelling reasons to go through the extra costs, most compounds will be sold with a certain level of moisture in them.

As far as VG is concerned, you can buy it cheapest at the pharmacy section of WallMart. Around $3 for 177 ml. It is USP grade and can be found in the hand lotion section. (Humco Brand)

PG can be had a most Tractor Supply stores for around $20-30/gallon. Not all locations carry it, so call beforehand.

The e cig companies are repackaging the same products and charging you a lot more money.
