    Nicotine Comparisons

    I think you mean Wang. It was not an ecig, it was a reactor vessel with glass wool soaked in e-liquid solvents. For temperature data, could be argued to be a good study, and useful. For relating it directly to ecigs, especially new-generation atomizers, I think this is very misleading. The...

    Nicotine Comparisons

    Do NOT confuse benzoic acid with benzene! They are not even remotely the same, other than the benz part of the name. Benzoic acid is a commonly used food preservative, as sodium benzoate (the sodium salt of benzoic acid). Benzene is a carcinogen. That said, I would prefer other acids be...

    Nicotine Comparisons

    Yes, in principle, but I have never done it myself. One would add a benign acid, like citric or pyruvic acid, until the pH drops to where you want it. Besides NN, I have seen this done commercially, Vermont Vapor, with citric acid, but not for the purpose of creating salts, just during...

    Nicotine Comparisons

    This rat study used (S)-nic (l-nic), not racemic. They did pay attention, and they were clear in reporting it in the abstract. Synthetic l-nic is certainly available for research purposes, but it is wildly expensive. To say that synthetic racemic nic is fine because you take synthetic...

    Nicotine Comparisons

    Sounds interesting, but I have not tried it. Not sure I will, since being in PA with a 40% tax I would have to (eventually) pay about $230/L. Another issue for me would be the specs, which I could not find on their site. I have heard this nic is not tasteless, which could be good or bad to...

    Nicotine Comparisons

    I know of another company synthesizing nicotine to get around the FDA regs for tobacco products. New Generation is the name. Thing is, this is NOT enantiomerically pure l-nic, it is a racemic mixture of d-nic and l-nic. Synthesizing just l-nic, which is what comes from tobacco, would be about...

    Yes, I think this is fine. As far as I know, as long as a product was on the market (and can be shown to have been for sale) before Aug 8, then it can be sold after Aug 8. So if Vendor X wants to sell diketone-free e-liquids manufactured and sold by Vendor Y, and they were sold before Aug 8 by...

    This is my understanding too. There are many companies displaying test results. The problem is that if the company had diketones in their e-liquids on Aug 8, then they cannot remove them from formulations, since this would create a new tobacco product. But I don't think there is anything in...

    Yes, evidently they are both using Chemnovatic now.

    Nicotine Comparisons

    I found it to wick well, vape well, and it didn't dry me out as much as PG. Maybe a touch more drying than VG. However, I didn't like the taste it had, and I found it to be a bit heavy in the lungs compared to my typical VG/water juices. I only vaped it unflavored with some nic. Had a slight...

    Liquid Labs is using 1,3-propanediol (sometimes called "PDO") to replace PG in their base.

    The Flavor Apprentice Flavoring Thread

    It's maltol, not ethyl maltol, which is 3-hydroxy-2-ethyl-pyrone.

    The Flavor Apprentice Flavoring Thread

    Maltol is not ethyl maltol, but they are structurally and probably taste-wise very similar. Maltol is naturally occuring, EM is synthesized. Probably both about the same inhalation safety, that is probably safe, but long term studies have not been done. Both are used to add a caramel/cotton...

    Carolina Extract nic is very expensive by today's standards. By 2011 standards, $90 for 0.5L would be considered a pretty good deal. Have not tried it yet. Why they have their 120 mL samples in a glass bottle with rubber stopper is beyond me, however. Rubber is more porous than LDPE, and I...

    Liquid extraction from nuts (walnut, almond, pecan etc) and safety?

    Well, I don't know how the FDA can keep people from buying flavors, which are used in food and drink products. I have not heard of there being restrictions on flavors, per se, but perhaps on flavored e-liquid finished products. It is possible flavor companies catering to DIY will have to...

    Nicotine Comparisons

    If you like RTS, then go for it. I find it too sweet and heavy for me, even cloying. In the beginning I liked the tobacco taste it had, but started to tire of the sweetness. That was from end of June. I have heard in recent weeks RTS is more flavorless, however. The RTS I got in June was...

    The only vendor I know of that ships in glass is Nude Nic and that is just for the Armor line of nic. Vendors generally don't want to risk breakage of big glass bottles in transit.

    Nicotine Comparisons

    I have tried it, and I like it very much. Has a touch more taste than the original TH, but much less than NicSelect or RTS to me. About the same pepper in the nose and TH as the original to me. If anyone as tried Hi-Liq nicotine, I think this new TH nic is very similar in taste, but much less...

    Liquid extraction from nuts (walnut, almond, pecan etc) and safety?

    I would not recommend vaping extracts from nuts, since they will be of high lipid content, not to mention proteins, neither of which are good to vape. Lipids do not expel from lungs well and can lead to serious health problems, and proteins will easily decompose into God knows what radicals and...

    flavoring stability

    I have found many flavors in plastic will fade with time. I try to keep my bulk flavors in glass now, and yes, for some I use the euro dropper bottles from here: Aromatherapy Dropper Bottles | Wholesale | Specialty Bottle Pick you color, then size. More size options with amber. Might be...
