Can someone help me work out ratios of nicotine solution to base?

[DsyF]

Hi,
I've found a supplier for nicotine solution and base mix who sells the product in glass bottles.
Having it in glass is a must for me, but it's making things complicated:

I'm aiming for a 50VG/50PG mix @ 1.8%
The nicotine solution is available as VG or PG @ 7.2%, so i need to dilute it 3x to reach 1.55% (i was planning on 1.8% but i think that'd make it too complicated)

Here's where it gets confusing; The base mix is available in 85VG/15PG, 70VG/30PG, 60VG/40PG
I'm not sure how i can reach a ratio of 50/50 diluting it only 3 times..

The closest i've got is: 160/140.. by starting with 100ml PG 7.2% and using the 70VG/30PG base mix:
PG - VG - Nicotine
100 - 0 - (7.2%)
130 - 70 - (3.1%)
160 - 140 - (1.55%)

Am i going about this wrong? It's a bit of a headache that's for sure.
How would you suggest i reach the desired 50VG/50PG mix at the right strength?
I tried a couple e-liquid calculators, but they all require your base liquid to be either PG or VG, not a mix of the two.
Thanks, D

Mixing to 1.8% is quite easy.
4 x 1.8 = 7.2 which is your starting point on nicotine.

So if you buy 100ml PG based nicotine you need to add 100 ml PG and 200 ml VG to get 1.8 50/50.

Thats translates to 100ml 60/40 and 200ml 70/30.

If you only need 100ml devide it all by 4.

Thankyou very much Richu75,

Can i just check i followed this bit correctly:

Thats translates to 100ml 60/40 and 200ml 70/30.

>
So i'd need to buy both the 60/40 and 70/30 base liquids - in order to make:
1 part PG based nicotine, 1 part 60/40, 2 parts 70/30 ?

The above recipe creating 400ml of 50/50 eliquid?
Much appreciated, (i didn't realize my maths had gotten so bad )

 

[Richu75]

Yes. It makes 400 ml of unflavoured 50/50 18mg nicotine base.

Calculate with me: 200 ml of 70/30 contains 0.7 * 200 ml of VG. 100 ml of 60/40 contains 0.6 * 100 of VG. Together it adds up to 140 + 60 ml of VG in a total of 400 ml.

The best help I can offer in my opinion is to use a calculator from one of the ones here.

Just a heads up about the above - The forum Mods strongly frown on discussion of nic strength in %, and they want it to be given in mg/mL on here. It helps to avoid confusion for other newbies to DIY if everyone "talks" about it in the same way, which is the way most suppliers sell it on their websites (ie. mg/mL rather than in %).

 

[DsyF]

Heheh, Thanks Richu75.
Cheers for the headsup JCinFLA that is understandable- i'll bare that in mind for future.

Most calcs do support nicbase in varying ratios, e.g. the ones SteveS45 linked too, which is a good one imho. Start with this e.g.: E-Liquid Calculator Ten Flavors with PG/VG Adjusting

Just a question...why don't you just purchase 100mg nic in either PG or VG (I use 100mg VG nic) then buy some VG and PG and mix it yourself so you can make the base how ever you want? That way you don't have to do all the math. Also like a comment above, use an e-liquid calculator and plug in what your working with (nic strength, VG/PG ratio, and flavor percentage) and it will tell you how much of what to put in your bottle. Then all you need is some blunt tipped needles and a few syringes and make your juice. Just my opinion. Good luck!

Is that a new policy? I wasn't aware that was an "official" position, just thought it was a good idea in general.

Probably from the EU, where you can't get it stronger than 72mg.

 

[mhertz]

I've never heard it myself, though trust JC if she states it. The issue with percentages is that many e.g. state 3% nic instead of 0.3% nic for 3mg/ml . Personally I don't see the issue whatsoever if stating it correctly, and all the nics i've bought have stated both numbers on bottle, though i'm of course not the one who sets out the rules or best-practises around here...

 

[JCinFLA]

I don't know if it's an "official" position or not. However, since probably June (when more people started posting about starting DIY) I've seen some mods correct some members several times...for posting in % instead of mg/mL, or at least in mg. Said in so many words that on the ECF nic is not to be discussed in %.

One mod even very sternly (and rightly so) told a member who was incorrectly telling a newbie what a certain % of nic was, compared to mg, and he couldn't see what was wrong with it. So he was sort of arguing about it with the mod,...who replied to "Just Stop It! Talk about nic in mg and not in %!"

In fact, the particular case above was because of an issue exactly like @mhertz said above, except worse, because it was about a much higher mg of nic!

From the EU? Not sure what you mean.

I see your in the Pacific Northwest. You would be able to order it in 100mg from a US vendor. I use 100mg. When I first started DIY I got in touch with @JCinFLA (we live 30 min away from each other and she became my DIY mentor) and she told me to get 100mg nic because it will last you longer. Say your using 100mg which is stronger so you don't have to use as much, which in turn your bottle of nic will last your longer and make more bottles of juice than if you were using 34mg nic. If your wondering what a good nic vendor is, @JCinFLA will be able to tell you where the best and cheapest place to get it. She is a deal finder so she could help you out on a vendor better than I would be able to.

Maybe I'm missing something here, but wouldn't it be easy to start with 50/50 100mg/ml and use a juice calculator for the rest of the mix?

MFS sells 100mg/ml in 50/50 mix for $50/liter. Mine is still water clear after 9 months of using it to mix juice.

@Wheelin247 - bwh79 was talking to me about "being a new policy" or something. Also, the person wanting the nic base is the OP, who doesn't live in the US! And EU is the European Union.

My mistake. Guess that I get for not paying attention to who was posting the comment. :face palm: lol

I (@bwh79) am in the PNW (*Pacific Northwest), and I do buy my nic in 100mg/ml concentration.

The EU (*European Union), however, has laws restricting commercial nicotine solutions to 72mg/ml (7.2% by volume) or less, which is why I surmised that the OP (*Original Poser) probably lives in that region.

Yeah like I said in my last post, I didn't realize who was posting the comment before I responded. My mistake.
