Pre-mixing water & VG nicotine base?

[markinohio]

I’m a total newbie, and mixed my first batch this weekend. I’m using 100% VG, and “thin” it out the final mixture with 10% distilled water. I’m happy with the results, but plan to try a few more small batches to really get it dialed in. However, I would eventually like to simplify the process and have a pre-mixed base that would just need the addition of flavoring to complete.

Are there any issues with pre-mixing DW with the base? That is, I would like to pre-mix a large batch of VG nicotine base, DW, and additional VG to obtain the desired consistency and nicotine level. I realize that the amount of flavoring added will impact both the consistency and nic level of the final product. However, I’m willing to allow both to vary by +/- 5%. I just want to make sure that pre-mixing with DW will not have any adverse effects on the nicotine base over time (less than 6 months storage time).

Any information would be greatly appreciated.

Thanks!

Water's chemical formula is H2O. It contains a lot of oxygen so pre-mixing nic solution with it included is not considered for any length of time of storage. The more the nic is exposed to oxygen the faster it begins to degrade. Maybe play around with just the plain vg and water to find the consistency you are looking for. But I would wait until I actually mixed up a bottle of ejuice to vape before adding any dw to nicotine.

Yes, it's fine, especially for non-long-term storage... Kurt recently did some calculations and admitted that he had over-estimated the bad(oxygen) effect of adding H2O in VG nic.

In a 50ml bottle just as example, even stored at room-temp, then a standard 4ml headspace in the bottle is roughly oxidizing 6.8mg nic in 100mg/ml nic, whereas with 20% water added, then if all oxygen reacted from the water, then roughly 0.4mg would oxidize from that of the 100mg/ml nic. Note, the oxidation is not in mg/ml, but in mg alone, meaning eg. from water alone added, then 100mg/ml would be 99.96mg/ml if all reacted and at room temp in a 50 ml bottle(headspace not counted here, just water effect)...

In short, it's fine I always premix with water about 350ml at a time stored in room-temp...

Oh, here's the post from Kurt on this: Nicotine Comparisons

Edit: Note, of course there's no need to add water to nic for long term freezer storage, but I answered above in regard to making premix for non-long-term-storage at room temp for easier DIY mixing... When you buy premix bases from vendors like inawera and many others, then they also add water often... It degrades it, yes, but for non-long-term, it's not an issue and the degradation is much much lower than once thought Even for long term, the effect is still so small, although preferably avoided of course if possible...

Oxygen in water formula cannot oxidize nicotine, it already oxidized hydrogen.

Nothing wrong with water in a base solution. But if you want to keep it for 6 months, apply usual precautions for nic storage.

So you disagree with Kurt on this which states it has an impact, although much lower than he previous thought? (In the example of a 50ml bottle, the small headspace was about 20x worse than e.g. adding 20% water...)

I don't know anything about it myself, but have also read before that the oxygen in water is bounded with hydrogen-bonds or something of that sort, so as it isn't free to react with other substances...

Please excuse my laymen's wording and understanding of this...

Very interesting info you lay out here btw, thank you

OK, I took a look at Kurt's post (thank you for link). We are in agreement here. Oxygen bonded in water molecules has nothing to do with nic oxidation. There is oxygen dissolved in water (and it is a very different animal), but in minuscule amounts, and anyway when mixing water and nic reaction will take place pretty soon, so storage will change nothing.

I would recommend against doing this to more than a 30 day supply. You may change your mind some day. You can always add DW but it's tough to remove it....

You can never predict when your preferences will change.

Ahh, thanks alot Alien Traveler, now I understand it i.e. oxygen as part of H20(bonded and non-reactable) vs. disolved O2 in water, like disolved O2 in VG. Sorry for stating an difference in opinion between you and Kurt because of my own failed interpretion of the subject.

Thanks mate!
