Olive oil VG

[mhertz]

Thanks for your reply ceeceeisme

If a product is 99.5 or over it's fractionally distilled and hence without impurities??? So in USP nic, there's no solvents like hexane in minute leftovers? Rhetorical question here, btw.

Personally, i'm no "health-nut" or how to phrase it... I have no fear whatsover over any USP VG and my interest in this is solely because i'm the "nerdy" type which likes to understand as much as possible with the interests I have. As I vape unflavored, and have noticed taste differences in both nics and VGs, then i've gotten samples of all the nics and VGs I can and test them for my own preferences, and it's here this issue stems from

Anyway, I respect your opinion, and much appreciate your patience with me on this, though I would also love to hear the input of any others possible in the know, thanks.

If the fractional distillation was perfect, then why the need to remove odor impurities afterwards and why can't it remove all water Rhetorical question again

Edit: Hmm, it doesn't make sense to me that you're both stating no possible leftovers other than water, but then in same breath state to wanting to know the plant source in your VG to omit india manufactured VG and jathropha leftovers???

Anyway, as stated, I respect your opinion and information(and patience) greatly. I don't wanna beat a horse to death or how the saying goes and so say thank you for a nice discussion. -Martin.

Edit2: In a pretty technical paper I found about USP glycerin, which also talks about this fractional distillation and other things way over my head, it's stated that the impurities are water and trace-leftovers off polyglycerols, which I looked up to be fatty acids and esters, meaning original feedstock, but again, in trace-amounts only...

USP Nic.... good question and one I'm not really qualified to address. Back in my university days the only liquid nicotine around was for pesticide use only. I'm pretty sure at that time nobody cared if it was contaminated. The concept of the "patch" was just being conceived for pharmaceutical use in humans and studies started in 1984. So without me taking some time to study the processes and standards I couldn't really comment however I am certain that fractional distillation would be employed in the final process to purify it to the best of the manufacturer's ability.

With regards to fractional distillation practices....

There is the optimal way, the cost-effective way and the wrong way. How is anybody supposed to know how stringently the processes are maintained and performed with any given manufacturer? (short of doing an analysis yourself). And how about human error or just plain laziness? What about corner cutting so an extra 0.002 cents can be made on the dollar? (yes, the zero's are in the right places!) How about another two dozen variables that can and do come into play when the almighty dollar is on the bottom line? This is why there are USP guidelines - without standards it's a free-for-all and anything goes.

I buy coconut VG so I know for myself that there should be no cross contamination of less desirable vegetable products or subsequent contamination involved in its manufacture and that high quality standards are generally being maintained. Does that mean there isn't contamination at some level (parts per million)? I dunno. I'm taking the suppliers word on it that they've done their homework. I only suggested that products from India could be avoided simply because I read somewhere about contamination stemming from Indian jathropha oil however I now I can't seem to locate that article. So I do hereby retract that statement - India has some fine pharmaceutical labs and there is no reason to avoid any well respected products from this country. Contamination can happen anywhere and be the result of many variables.

And sorry if you feel I am only quoting your "small talk". The questions you are asking would be better answered by someone who is an organic chemist. I am a metallurgist with only one year of organic chemistry under my belt. Organic chemistry is a massive field as is metallurgy. A lot of what I learned my first year has been summarily discarded as not relevant to my career.

Thank you again ceecee for your comments, it's very much appreciated USP nic, from countless COAs i've seen, are vastly nic and water, but extraction-solvent like hexane can be available, and is, as i've seen it occasionally on COAs(when they bother listing the testing-element and don't omit it, or includes it under total impurities), and is allowed per USP, but of-course in trace amounts... Then there's also the other alkaloid impurities which also is allowed, but usually in under detection-limits in trace-amounts for premium nics. I believe 0.8% is allowed in total or 0.5 or alike, but again, vastly under usually in todays standards...

Thankfully, hexane is not considered to be carcinogenic (and is delicious.... lol... just kidding!).

I understand people want top purity wherever possible and I'm no exception. The way I see it though, even with nicotine and flavoring, vapor is far less toxic than cigarette smoke and I would've never stopped smoking if it wasn't for APV's. It's not without risks, just a far better alternative.

One of the reasons I will never use the VG you can buy that is meant for topical use and not strictly for vaping. It may be a bit overly cautious but it is just my preference.

I don't think that's overly cautious as I won't buy it either. If I see I'm running low on VG (like when I start using my last liter) I order another gallon.

Personally, I would buy from whoever, as long as pharma-grade(USP and/or EP, BP, JP etc), tastes good and is economical, in that order. I know a place that e.g. sells VG for horses, and the posted COA is some of the purest glycerol amount and lowest water The very same manufacturer is used from vaping-stores some other places, as I can see from the way the COA is setup and wording i.e. same manufacturer. Big VG manufacturers that makes a USP product sells there product to whomever needs it...

If I can't tell a difference in cheap and expensive products(as long as USP), then I would always go for the cheap... I do strive for finding the best purity and such from the cheapest offerings(if otherwise comparabel), just because, why wouldn't i....

Yup, I would probably buy that too. In my case, the two drug stores in the town I live closest to have no USP purity noted on their labels and are simply called "Glycerin" . Even if they were high purity and noted as "vegetable glycerin" they are pretty expensive for 500 ml sized bottles. Thus, I've found an online supplier with a consistent supply of VG I trust and is USP 99.5%. It's also one of the least expensive options here in Canada, which can be pretty darned expensive for PG and VG (compared to say, the US). If it was cost effective with the shipping included, I would order from south of the border.
