    Random DIY mixing and More

    There's only one monograph in the USP for glycerin called glycerol, which demand 99 or 99,5% purity of glycerol in the glycerin. So USP purity is USP purity, period, and then there's the FCC too, e.g. also for glycerol. What I think you're talking about, is that a manufacturer can list in the...

    Random DIY mixing and More

    I respectfully disagree. USP refers to a single "pharma-grade" standard(because drugs sold in pharmacies need to comply to that plus FDA GMP guidelines, so hence the term "pharma-grade ), and then there's the FCC(food chemical codex), both under FDA audit. Actually, USP has overtaken the role of...

    Where do you guys get your Nicotine Base?

    I thought so too, before reading they state they will no longer offer nicselect and " Pricing will also be significantly less due to fact that we now control the tobacco that gets purchased, to how its extracted etc. For once the ball is in our court and we are no longer at mercy of other...

    Nicotine Comparisons

    I find it really odd that alchem wouldn't deliver new pure nic to nicotine River so they had to make there own trademarked brand purnic, also from India, bgp healthcare im thinking but just a guess. I could understand if alchem just ran out momentarily, but it didn't sound that way from the...

    Nicotine Comparisons

    Thanks alot Vapntime, much appreciated. About pink nic, I tend to trust inawera and chemnovatic on the matter, e.g. small quote by chemnovatic: "Some PG/VG also change the color to light red when mixing with nicotine, even if they are pharmaceutical grade." Quote: 5 steps to high quality...

    Nicotine Comparisons

    I apologise for forgetting to omit the source link, thank you. I have asked a couple of times in the past if cxtc customers would please post the COA here, but none replied. Im no expert, but isn't the hexane or whatever used, just used for extracting the nicfrom tobacco, and where...

    Nicotine Comparisons

    ... been out of the loop for a minute because of some sickness, anyway, I just now learned a few things about chemnovatic I wanted to share. They actually extract there own nic from tobacco themselves, plus, they use supercritical extraction, you know, the non solvent CO2 based extraction...

    Cas Number of VG ?

    The difference is that it's a typo simply, as there's no CAS number issued named 56-1-85. You can see however, that it's a matter of two adjecent chars that's just been reversed by mistake. As the good BrotherBob uptop commented, then any pharma-grade VG is fine for vaping, and correctly...

    Nicotine Comparisons

    Personally i'm pretty sure people getting bad peppery nic is the vendors processing, as already stated. I always buy my nicselect from between a few vendors which i've mailed with before and know they get there nicselect pre-dilluted into PG or VG from alchem themselves from a...

    Nicotine Comparisons

    Thanks, and indeed I could be wrong too, so please don't take too much "fact" into my theoretical "ramblings", lol! :) Sure, impurities can also give enhanced TH i'm sure, but I just mean that atleast ECX i.e. nicselect is not a dirty nic atleast when talking it's purity - as I said, they added...

    Ejuice calculator (added quantity calculations)

    Yup! :) it works on any platform as only needs a spreadsheet-type app to use. It works fine also with a browser and google docs, the free online office-pack.

    Nicotine Comparisons

    Lol, yeah I know, I often switch a little around on the things that interest me, and DIY/RBA/Mods has taken a back seat for me for some time(though still vaped like crazy and DIY'd of course), and i've been on some other forums mostly linux related, and read alot up on likewise stuff, but am...

    Nicotine Comparisons

    Also, as I said, all nics i've tried taste like pepper at mid/higher strength. It can of course be speculated that it was all bad nic, but my own theory is that this is normal because nicotine is an irritant to mucous membrane, just like various spicies like chilli etc, so no matter if zero...

    Nicotine Comparisons

    I think nicselect is a very clean nic with regards to off-taste. However, it is pretty brutal at it's TH though. It used to have a very slight off-taste tasting like glue or alike, but that is void in newer times, and the last several batches i've gotten has been pretty much clean in taste(at...

    Where Should I Buy DIY Supplies for Shipping to Israel?

    My favorites in EU for nic and PG/VG: UK, Alchem nic blended by Alchem themselves and just rebottled, so spot on accuracy on mg: 7.2% Liquid Nicotine | 72 mg/ml PG Nicotine | 72mg/ml VG Nicotine Spain, as said, Pink-mule, trusted chemnovatic supplier: NICOTINE BASES (I include this because...

    Is there a difference in pg/ vg quality?

    I agree that nicbases isn't USP(as isn't possible), but is using USP nic to make said base, as can be seen by the many vendors which lists COAs for there base-components. Think nicotine-river and vaperstek etc, using alchem and chemnovatic USP nic. Also, for eliquid, I believe nicselect is very...

    Is there a difference in pg/ vg quality?

    Sorry, but yes it is USP... Non-USP nic is also under 99% before cut. The completed base isn't USP, as no USP article to comply against for such exist, but the base is constructed of USP-complaint base-materials blended together to a new product.

    Nic has oxidized

    My nic was actually 10 months old and not 6, after looking up the date of my order-mail, though it wasen't very oxidized to be fair... I still vape it right now and it's still fine... However, sometimes when I just refill my tank, and the chamber gets a little flooded(OBS engine, slightly too...

    Nic has oxidized

    I just made this months 1L unflavored mix using some older nic this time which had stored for 6 month in plastic in dark cool area and with lots of airy headspace in bottle(250ml bottle only under 1/4'th full and with 20% water added from manufacturer). The nic is very good quality(nicobrand UK...

    DW in nicotine base

    Well, some add DW as part of a recipe so as to get better wicking without diluting the flavor, nic, PG/VG ratio further down, which I'd also recommend instead. Also some use DW as an ingredient to change/enhance the flavor or to enhance TH(DW reduces droplet size of vaporized VG + lowers...
