PG-USP grade & alcohol

[gary777]

Does the PG with 0ml of nicotine sold at various on line E-cig sites used to cut e-liquid, have alcohol in it?

I saw some at a local pharmaceutic store, I took a whiff and could smell alcohol in it. The bottle said it was food grade but I did not see USP on the lable, just propylene glycol food grade...

The price is a lot cheaper than what online sites are selling it for, but is it the same thing as the PG from the online sites? I have heard that it was, but am leery because of the alcohol smell.

Thanks

It shouldn't, but I wouldn't use anything that doesn't say USP grade. Surprised what you found at a pharmacy didn't say that on it. Conversely, if it says USP on it, it doesn't matter what it's packaged for, it's fine to vape.

FWIW, I just bought a gallon of USP PG at a Tractor Supply Co. for $20. Way cheaper than anything online. It was in the farm animal health section, though I have no idea what they'd use it for.

I'm kind of miffed that TSC in the US sells PG but not the ones in Canada.

In any event, I can't imagine why store-bought PG would be cut with alcohol. The stuff you get from vendors certainly should not be -- it should be straight up USP grade PG with no additives, unless you get it flavoured, in which case, the flavouring may contain alcohol.

It is used as a cure or preventative for some condition pigs get. There is probably some place in Canada that sells it.

PG is halal so it can't have alcohol

I'm sure there must be, I just haven't found one yet. I can get 100ml bottles of VG almost anywhere (though at $3 a bottle it's pricey for larger quantities) but no PG yet -- though since the applications for PG differ I'm almost certainly not looking in the right places.

Try a Compounding Pharmacist if you can find one. In the US that is what they call the ones that have special training to turn pills etc into liquid medication for children. I've heard they usually have or can get PG. Propylene Glycol

PG and VG are pretty similar chemicals, both three-carbon glycols (diols; having at least 2 hydroxyl groups). PG is (1,2) propanediol and VG is propanetriol (or glycerol); so 2 and 3 alcohol groups (-OH) respectively.

So PG USP does contain enough alcohol to smell it?

Pg usp I have is odorless, no alcohol scent.

If you can smell it you'll taste it when you vape. Could mess up a good recipe. Prolly going a tad more expensive will save you $ in the long run. Box Elder Chemical Supply .com is having a 40% off sale through today. RTSsvapes .com also has good prices on PG/VG and nic bases in both.

Technically PG and VG are alcohols (sugar-alcohols, having qualities of both groups) but they are not ethanol, the one people drink.
