So I bought a 100mg bottle of nicotine and wanted to dilute the nic down to 20mg to make it a bitsafer to work with. I've seen a lot of people talking about adding Distilled Water in nicotine bases.
I too would suggest diluting your nicotine
base (if that is what you prefer) with PG, and/or VG, and leave the distilled water (if you want to use it at all) for when you mix your individual recipes.
You mentioned "a lot of people talking about adding Distilled Water in nicotine bases." But, I think if you go back and reread those comments, you will see the majority were likely talking about doing so during the recipe phase of mixing; and not prediluting straight nic base.
I would be concerned about adding DW directly to my concentrate; as
I don't know if this
might provide an unwanted oxygen source. Oxygen, along with heat, and light, are the three things we DIYers try to minimize exposing our nicotine concentrates to, because it will accelerate oxidation. Oxidation
can provide unwanted flavors, and throat hit, as well as a decrease in potency.
As for diluting for safety's sake; I would agree with what has already been said
in general. For the average, healthy adult, home DIYer, the risk is probably negligible. I, like the previous posters, work with 100mg/mL nic concentrate routinely, and find it unnecessary to dilute it (with anything) prior to the final recipe. But, for a
minority, extra care may indeed be necessary.
I have read one ECF participant's experience, that ended with her having to seek emergency medical treatment, and I
believe she was working with significantly lower than 100mg/mL concentration. Now she freely admits to having a skin condition, that leaves her sensitive to
many different chemicals, so her reaction is not surprising. And, in two and a half years of reading virtually every DIY-related post here on ECF, it is the only report
I have come across.
I only mention it, to say that
all nicotine concentrates deserve your respect and attention (regardless of concentration); both concerning storage, and handling. I suggest being aware of any special physical limitations for anyone who might come into contact with the concentrate; use common sense, and avoid distractions, while mixing; and have a plan for accidental spills, or contact,
before they happen. A little bit of thought, and preparation, goes a long way toward keeping a nuisance from turning into a disaster.
I just wanted to ask if it's absolutely necessary to add DW in the mix if my base isn't 100%VG. I want to make a 20mg/ml 20%PG 80%VG mix.
DW is never "absolutely necessary," unless you are avoiding PG,
AND you find your recipe too thick (viscus) to wick properly,
in your preferred atomizer. Some attys will wick 100% VG just fine without any dilution. Others require something, to thin out the mix, before a satisfying vape can be achieved. That something will most often(?) be PG, DW, or some combination thereof. But DW is never "mandatory."
If I had to
guess, I would guess that a rather large majority of DIYers, do not use DW at all. I don't often see it mentioned in recipes (though that could simply be from omission; the way PG/VG ratios are often omitted), and I don't often see it discussed. My own experiments with DW, yielded little (if any) benefits, so I abandoned it after just a few trials. Of course, others (such as
@glasseye) find it beneficial, and I fully respect their preference. I bow to their experience and knowledge, to discuss why, when, and how, best to use it.
