Mixing Freebase and Salt Nicotine!

E-liquids General
1

I have access to 250mg/ml Salt Nicotine and 100mg/ml Freebase. Both are 100% PG.

I want to make hybrid nicotine 80/20 base using both.

These are my calculations:

60ml Freebase Nicotine (100mg)
60ml Saltnic Nicotine (250mg)
40ml PG
640ml VG

This will get me 800ml of 26.25mg/ml nicotine base liquid.

Now the concentrates I will be using are also 100% PG, if I want to make 100ml of ejuice with 30% concentrate and 70% base. What would be the vg/pg ratio of this eliquid? I guess around 67vg/33pg.

I used my tiny brain to calculate this so please correct me if I am wrong.

Also this base will be enough for like 2 years, storing it in a 1 litre amber glass bottle will keep it in good condition?

If i remember correctly you should never mix freebase and salt nic.

No reason to not mix the two. There are no weird chemical reactions that I’ve read any where.

Welcome to ELR @ila420. TBH, not sure why you would want to mix Freebase and Salts, as they are really designed to be used differently, not really together.

Salts for higher NIC level juice, often times MTL, whereas Freebase for lower NIC levels, typically DTL vaping.

My recommendation would be to cut the higher level Salts, down to 100mg, for MUCH easier mixing. This way, both your NIC’s will be 100mg, 100% PG, which is not only safer, but again, much easier to mix with. Typically you want your base NIC to be the highest strength, or non diluted, that way, when you do mix, you will need very little of it in the finished mix, as opposed to a very diluted base NIC, where you would have to use MUCH more of it.

The best way to store NIC is in the freezer, and broken down, into numerous smaller, glass bottles. This way you can have one “working” bottle, that gets taken out of the freezer, used, then put back in, whereas the rest stay cold and unopened, as “storage” bottles. You never want to continuously open a large bottle of NIC and put in and out of the freezer, as it will start to oxidize your ENTIRE NIC supply, every time you mix. FAR better, to repeatedly open and close ONE smaller bottle, until it’s empty, then move onto the next one.

As far as this, I’m not sure why you would spec out 30% concentrate, and 70% base, as it’s far more efficient, to work to a set final NIC level, like 3mg Freebase, or 24mg Salts, etc. The final ratios between NIC, Base, and Flavors will be sorted out by the ELR calculator.

In closing, if you are newer at this, even 100mg NIC can be dangerous, and 250mg Salts DEF. can be. Make sure to use eye and hand protection, and be careful if you’ve never worked with higher level NIC before, and obviously clean everything well, and keep away from pets and children.

Thank you for the detailed reply, the reason I want to mix is to get the throat hit from freebase as well as the smoothness of salts, I cannot go above 18mg with freebase and even at 18mg it will be very harsh.

I started vaping around 4 months back after smoking cigarettes for about 20 years, I started with 50mg salts and moved down to 30-35, now I want to make my own eliquid around 25mg, I am from Pakistan so dont have enough choices, disposables are everywhere, very difficult to find good tobacco flavors in 25mg.

The nicotine I can get is 150mg/ml, 250mg/ml in salts and 100mg/ml freebase. I imported the concentrates from UK, due to regulations have to rely on local vendor for nicotine and pg/vg and there is only one such vendor in my city.

Currently I am mixing the ejuices for vaping like 50mg salt tobacco flavor with 3mg/6mg fruity/dessert freebase.

It is not necessary that I mix saltnic and freebase, I can use 150mg/ml salt nicotine with the concentrates if the end result wont be satisfying, I have seen some UK vendors selling 72mg/ml hybrid nicotine by mixing both freebase and salts. So I thought it can be done when it is available to purchase.

Well congrats on quitting smoking. I’d be leery of pre-mixing large amounts of NIC, only because then, you’re stuck with it. Maybe start with small batches first …

Hi @ila420 and welcome to ELR.
In addition to what has been said, because I do not see it stigmatized by others, the operating temperature must be considered as a fundamental aspect of nicotine salts: above 200/250 Celsius degrees this type of nicotine releases highly harmful substances, for this reason it is mainly used in devices that operate at low temperatures such as disposable ones.
Nicotine salts must absolutely be used with caution and mainly in TC or taking care to empirically maintain low temperatures.

I’ve only used salts since I started mixing and they are fine at higher wattage.

well anecdotally i’ve heard the salt nic can actually turn your freebase into salt nic when you mix them

this was talked about in the deeperDIY sub on reddit which is home to some serious scientific people that work with chemicals for a living

theoretically there can be leftover acids from salting process that can still be reactive. in practice it might not be much of an issue i dunno

your aware there is a calculator?

@warkwarth I can 100% see that happening.

me too i’d say its highly likely to happen, how much freebase turns to salt really depends. could be a little, could be all of it maybe?

it would be really inconsistent long term across nic batches

And THAT, is probably the WORSE case scenario in regards to NIC. No one is titration testing before mixing every time, and you COULD end up with completely different NIC levels, unexpectedly.
