I use 10% nicotine, and I find it a very easy dosage to calculate, so I put it into smaller bottles and the rest in a box in the fridge.

If I want to make my mix at 12mg/ml (of nicotine), I use 1.2ml of my 100mg/ml and 8.8ml of PG/VG/flavoring.
If I want 18mg/ml for my mix it's 1.8ml of nicotine at 100mg/ml, and then I add 8.2ml of the rest.

You could make up some bottles of the right dose, but you do need to count how much flavor you'll be using, which of course, changes depending on the mark, the flavor used, etc.

If you're worried about kids or animals, you can buy a metal file box or cash box to lock it in, and remember where you put the keys ;)
I don't have young kids, and as I keep my mixing gear in a plastic closing case the cats and dogs can't get it. The big bottle of nicotine is in a small fridge in my room, so no one else goes into it. I don't think it's necessary to keep it in the fridge, but for me at the moment it works out as being practical.

When I handle a 100ml bottle of nicotine it is much easier than handling a liter or half liter bottle, I find, and it avoids spills. I do have a 100ml syringe and a sort of 2ml diameter tube that goes on it. Really essential for VG, and I use Nic VG added to VG at 15% water, so it's all pretty thick stuff. It also makes filling bottles with the nicotine, e.g. 250ml or 100ml bottles for ease of use, more or less accident free. I know it is advisable to wear rubber gloves when you transfer 100mg/ml nic, but if I'm sure enough I won't spill, I admit I don't as they're such a hassle to work with. I don't advise any one to not wear gloves though. But remember it's not just your hands, but legs, feet etc., that risk spills. I find access to water to be a good safety system.

If you know in advance, however, what amount of flavor you'll use in all your mixes, you could make up a bottle of 100ml at the nicotine dose you'll be needing. Then it's a question of putting your flavor in and filling the bottle from your pre-dosed nic/VG/PG bottle.
Always put a CLEAR label on your bottles containing nicotine. And its' dose, which helps to cut out accidents.

An example:- I use M+P's flavor at 15%, so to have my dose of nicotine at 15mg/ml I need to mix it so that I use 15 mg of nicotine at 100mg/ml for each 70 mg of VG/PG. This is close enough to 20% for me to mix bottles of nicotine/VG at 2% nicotine per ml. Or for 40mg of VG I add 10 mg of my 100mg/ml nicotine. OK it's not spot on, but the difference won't be unpleasant, or dangerous, or leave my tongue hanging out for more nicotine.
And I label the bottle as Nic/VG at 20mg/ml, for preparation with M+P eliquid.
Or even better I add the flavor and it will have a nice long steeping, and decante 20ml bottles of the ready made eliquid as needed. It only gets better with time, a bit like old whiskey.
But to do that you need to have enough flavoring, and be sure of what you like ;)

If you change taste or are starting out on DIYing your juice, I'd honestly keep it at 100mg/ml, and use a small, 100ml bottle for mixing sessions.

Whatever, however, enjoy your mixing, and keep vaping, whatever the PTB's say :D

So I can cut the pg based nicotine down to the desired amount using just pg? I am just trying to make it easier to work with.


We need a little more information such as your final PG/VG ratio. For instance is your final bace going to be 70PG/30VG or 50PG/50vg or 70VG/30PG. This would determine how much plain PG or VG you need to add to your 100mg NIC solution.

I guess I should be a little more clear , my fault .I have a bottle of 100mg nicotine and is there a way to dilute it down to 6,12 and 18 ahead of time so I don't have to handle the 100mg every time?

Once you have have your ratio decided on then what was explained previously would apply. What you should get is the e-juiceme up calculator. It will figure this out for you.

If you just want to cut that 100mg NIC down to a lower level for safer handeling. dilute it by half with plain PG. For example adding 10ml of plain PG to 10ml of 100mg NIC will make it 50mg.

This is what I'm trying to do but I want to make it 6,12,18 etc
 
I just want too make sure I am using the calculator correctly are these the right ratios to mix 200ml of Nicotine using 100mg Nic?

18mg nic= 36ml nic + 164ml PG

12mg nic = 24ml nic +176ml PG

6mg nic = 12ml nic +188ml PG

Yes, those are all correct. If you are good with algebra and want the general formula for calculating concentrations in mixes (for checking the calculator output), I have a blog that describes it.

So when I want to mix some juice after dilution and I use the calculator what do I put for nicotine strength and target nicotine strength? When I put the strength as 6mg and target at 6 it tells me I need to add more PG and if I enter 6 as nicotine strength and 0 as target it doesn't give me the PG/VG ratio am I missing something?
 
That probably relates to the issue with pre-mixing that others described above. If you start with 6 mg/ml and then add other ingredients that don't contain nicotine (e.g. flavorings), your final nicotine concentration will necessarily be less than 6 mg/ml. So to end up with 6 mg/ml, you need to pre-mix the base at a higher concentration, which is determined by the amount of flavorings you will add. So the chicken wants to come before the egg, so to speak, since the amounts of flavoring will vary some between recipes. If you do not need exactly 6 mg/ml, you could increase the nicotine concentration of the pre-mixed base by 10% or so and your final mixes will probably be in the neighborhood. My best suggestion there is to play around with the calculator doing some trial and error to see what will work for you.

And if you start with 6 mg/ml, there is also no mathematically possible way to end up with 0 mg/ml (although you could drive it close to zero with enough dilution).

But I know very little about the calculator applications since I do my own calcs in a spreadsheet I made, so maybe others can help PG/VG ratio issues.
 
I am mixing the nic 100%PG
.Normally I would put something like this

Nicotine strength :100mg
Nicotine Target :18mg
Amount to make :15ml
Flavor :15%

And it would calculate everything.
Now when I enter it like this it gives me the error messages my post above.
Nicotine strength :6mg
Nicotine Target : 6mg
Amount to make :15ml
Flavor :15%
or
Nicotine strength :6mg
Nicotine Target :0mg
Amount to make :15ml
Flavor :15%

Flavor :15%

Both of those scenarios are mathematically impossible, for the reasons described above. The calculator cannot enable you to defy the law of conservation of mass.

So if I have a nicotine base thats 6mg 100%PG how would I enter it into the calculator to have a strength of 6mg or is it impossible?
 
I think I answered my own question with you guys help lol sorry I'm a little slow sometimes. So I think I can use 12mg to make a 6mg an 18mg to make a 12mg and 24mg to make 18 etc etc so for future safety and simplicity it's probably best just to make a 24mg base that I can use in everything 18mg and under lol is that right?

That will work (a 24 mg/ml pre-mixed base), except that reaching 18 mg/ml might be difficult for a recipe that has more than 25% total combined flavorings. But that is a heck of a lot of flavorings, and not many recipes would use that much (most people here seem to think that 20-25% total combined flavorings is as high as you should go, and many recipes use a lot less).
