Is there a mixing calculator that takes into account the PG / VG content in nicotine?

Thanks for the reply @AndyC1971 and @KulrMeStoopid.

I've been on and off about mixing for a while and all that shite in the wee hours of this morning actually got me thinking about % ratios (so some good did come of it) and reading some of your posts KMS has 're-invigorated' me into mixing. I used to mix up a vanilla custard that came out fine so I don't know why I ever stopped really but if I venture back into it I'd like to be a little more accurate, hence this post.

If I use a 72mg nic then the % of the nic in the VG bottle would be minimal as far as ml is concerned so using your method Andy you'd have almost 50% vg and if you went for a standard mix of 2ml flavouring then that would mean according to your calcs that there'd only be 30% PG. IE a 50/30 mix rather than your preferred 50/50 mix.....I don't want to get it to laboratory standards () but just want to understand your 'thinkology' behind it.

Once again, thanks and all that - SB.

AndyC1971 - Sorry to be a pain and I'm not trying to be a dick etc' but I just wanted your thoughts on the above post. Thanks in advance - Jase.

No, to me it is a 50/50 mix, as I take the flavourings as being a part of the 50% PG. The PG base far exceeds that of the flavouring in that part of the mix, as @Fleabag eloquently mentioned in the dark early hours of this morning.

This is how I look at the breakdown of the mix: -

VG Part

VG Nic
VG

PG Part

PG
Flavouring (In PG)
Ethyl Maltol (In PG) buts such a minute amount

PA Sweetner just dissolves if added.

This to me is good enough for home mixing, if I was to sell, then I would look at a better way to comprise this mix. Remember using syringes is not an EXACT measurement.

EDIT

A better way to describe it, is forget about the 3ml of PG for a moment, and concentrate on that 2ml of flavouring. The composition of that flavouring, is predominantly PG, so you can add some of that 2ml to the final PG content.

Brilliant, that's exactly what I was looking for. I was taking it that the flavouring was 'neutral' when in fact it acts as PG. I know I'm never going to get it exact but I couldn't understand why I worked it out to be 30% PG and you 50% but now I understand.

Thanks a million for the reply - Jase.

no worries fella, not saying its perfect, but it does me

We have recently released our calculator

Maybe it might help

Here are two and really like using

Ejuice me up: ejuice.breaktru.com/

or

(sorry the link to this last one is no longer there, but if you can find a copy it is very good)

I use the ejuice me up one from breaktru which is really good.

You can't get it bang on exact unless you know the PG ratio used in each individual flavour if you're using PG flavourings.

PG based flavours vary from around 50% PG to around 90% PG - for DIY mixing purposes you just set the calc to assume 100% of the flavour is PG and that gets really close to the true number.

Here is an example with some maths.

Aim is a 50/50 mix for 100ml at 12mg/ml strength

We use 50% VG 50ml
72mg Nicotine in PG 16.67ml
PG 18.33ml
Flavourings (in PG @ 15%) 15ml

If you want to be very accurate then we know that our PG flavours contain 70% PG and 30% actual flavourings so 4.5ml is not PG and also 1.2% is nicotine so 5.7ml or 5.7% of the mix is 'other stuff' 44.3% is PG and 50% is VG.

This though is "close enough for govt work" as they say.

If you got really picky you'd actually take the 'other stuff' out of the equation and your mix would then be 5.7% 'other stuff' 47.15ml VG and 21.18ml PG and the nic and flavours as before.

A few % either way isn't too bad. As you can see working with a fairly large 100ml mix you still need to measure down to the hundredths of a ml to get it exact.

[warning random tangent ahead]

A flavour is a mixture of flavouring molecules that is then mixed into a carrier solution as just the flavour molecules themselves are going to be way overpowering for a normal person (i.e. someone who doesn't have the capacity or the time to accurately measure 1000ths of a ml) to easily use and there are issues with evenly mixing too if it has nothing to mix into.

Imagine your West Indian adopted aunt who is a bit OCD makes you "Rice and Peas" She makes up a big panful with 1kg of rice and 1kg of peas, and she mixes them really well when she cooks them up. Being the OCD old dear that she is she wants to give you exactly the same amount of peas as rice "otherwise it be tastin' no good!" Rice and peas are different shapes and sizes so if she just dollops you a out a bowlful the mixture won't be perfect.

If she adds water and then puts the whole lot through a blender then every spoon will have an even mixture in it. Same thing goes with flavour molecules, adding them to a carrier liquid is a bit like blending them into soup.
