That was a very interesting read........
ETA: Funny, they were asking the EXACT same questions back then, seems like in 6 years there would be some answers already.

Yeah, and unless you do a true "Blind" test where the subjects cannot see the color of the nic, it's going to be nearly impossible to get any objective data correlating color change (due to oxidation) with nic that no longer tastes "fresh".That's a Tough one.
Because I have read posts where People say that there Nicotine Base tastes more Harsh over (Room Temp) time without a Darkening of Colour. And I have read posts where People say their Nicotine Base has changed Colour, but the was No Difference in Taste.
Taste is All so Subjective.
The closest I've seen to pinkish nic was one of the samples I got for the "blind comparison". It was the "A" samples here in this pic:BTW - Have you ever heard of a Nicotine Base turning a Faint Pink Colour?
We probably shouldn't use that terminology. Although we mostly store nic base in the freezer, it remains liquid the whole time, so there's no phase change or crystallization involved as there would be with something that actually freezes.I'm wondering if repeated cycles of freezing and unthawing might have some adverse effect on the nicotine base...

I know I like my nic as clear and colorless as possible.

Yep, those were asked in that thread 6 years ago too.Yeah... You would think so.
But then again, I can remember Threads about at what Temperature VG breaks down at? And are our Atomizers even Reaching those Temperatures?
So I guess the Wheel just keeps Turning. And sooner or Later, it goes around another Full Circle.

..., we know damn good and well many of these questions have been researched thoroughly, those really in the know are just keeping it all close to the vest.
If I'm going to do a test it will be with a little sample size not 2-4 ounces worth.Yeah, and unless you do a true "Blind" test where the subjects cannot see the color of the nic, it's going to be nearly impossible to get any objective data correlating color change (due to oxidation) with nic that no longer tastes "fresh".

I'm no expert, but few use a special non-chemical method(cxtc) and most the "normal" methods with heptane or whatever solvent, I think it's maybe called liquid-liquid extraction or something but again not certain. I believe where they differ is the after-purification steps and how many, done post-extraction, e.g. I read that alchem introduced additional purification on top of the normally done, to highten purity for there nicselect, but I would think most others do the same by now or maybe even better who knows. Sorry, i'm not in the know so probably shouldn't have posted anything...[...]
Hey here is a Question.
Has the Nicotine we use all been Chemically Extract from Tobacco using the Same Process? Or are the Multiple ways that Nicotine can be Derived that are cost effective in the Nicotine Base Market?
We haven't yet (but plan to once we have the inhouse GC/MS up and running,) run repeated tests on samples as they age, and exposed to different factors (light, heat, oxygen,) to compare the results over time.

I read an article about tobacco processing awhile back that indicated most extraction was done using high pressure steam distillation. That said however, I am unsure how dated that information was so it may not be the case any longer.
Mine tends to turn pinkish after awhile. I figured I just needed to wash my syringes better. Well, this explains my 3rd arm....
New Samples!
Over the weekend, I ordered some 120ml bottles from VT, hoping that they would arrive in the same clear (#1 PET) plastic in which I've gotten nic from them in the past, so I wouldn't have to open them and expose them to additional air for this experiment. They arrived yesterday (fast!) and indeed, that's exactly what I got:
First is their "Premium" nic in PG:
This about as colorless as any nic I've ever seen.
Next is their "Throat Hit" in VG:
This has a slight straw-colored tint to it, but not much.
Last set their "Throat Hit" in PG:
This is closer in (lack of) color to the Premium. However, I'm a bit skeptical as to the validity of the test with these samples because, unlike the other two sets, the two bottles do not have the same date/lot code.
One more pic of one of each, side-by-side:
I've not opened any of these. All I've done is crank the ("child-proof") even tighter than they were and apply my trademark white electrical tape as an additional seal to the caps, as well as labels, "RT" for the samples that are being kept in a metal box (to keep out light) at room temperature, and "FR" to the ones that are being kept in my freezer.
