Mixing Calculations for Newbies...

[jbchickenhead]

OK guys, I am sure some of you have dreamed about mixing on your own, but are intimidated by how to do this. Here are a few easy calculations to make this a plug and play operation for you:


Determining the volume for PG/VG Mixture:

Multiply desired volume (of total mixture) by whatever percentage of PG and VG you would like

Example: 80PG/20VG for 50mL

PG: 50mL x 0.8 PG = 40mL PG

VG: 50mL x 0.2 VG = 10mL VG


Determining the ratio of Nicotine Desired:

Multiply desired strength by desired volume then divide by nicotine base strength:

Example: 24mg/mL target with 60mg/mL base Nicotine with an overall desired volume of 120mL

Calculation: 24mg/mL x120mL = 2880mg; 2880mg/ 60mg/mL = 48mL


Determining the amount of Flavoring to add:

This is slightly more complicated, as it requires some research to find out what percentage of flavor to go with.

All you would have to do is multiply the percentage of the flavoring (divided by 100) by the desired volume:

Example: 6% TFA Cinnamon in a mixture of 150mL

Calculation: 6/100= 0.06; 0.06 x 150= 9mL of TFA Cinnamon


Subtracting PG and VG in Nicotine Solution

So here is a formula for you to use (example is in 100mL size, 100mg/mL 50%PG/50%VG Base Nicotine; 24mg/mL Target):

1. Calculate the amount of PG and VG you will need for your mixture
2. Calculate the desired level of nicotine for your mixture
3. Subtract levels of PG and VG from mixture from answer in #1

Example

1. 80%PG/20%VG Mixture, 100ml (0.8 PG x 100mL = 80mL PG)(0.2 VG x 100mL = 20mL VG)
80mL PG; 20mL VG
2. 24mg/mL Target (24mg x 100mL)/100mg/mL)= 24mL
24mL 50%PG = 12mL PG; 24mL 50%VG= 12mL VG
3. Initial 80mL PG - 12mL from Nic= 68mL PG
Initial 20mL VG - 12mL from Nic= 8mL VG

68mL PG + 8mL VG + 24mL Nicotine = 100mL Total Solution

I am pretty decent at calculations as this was pretty much my whole college/early professional life, so don't hesitate to ask questions...

Thanks,

Alright,

So let me get this straight; So these are the flavors and percentages you like:

Flavor #1 @ 5%
Flavor #2 @ 7%
Flavor #3 @ 12%

Option #1: Now are each of those the percentages alone (For example you like 5% of Flavor 1 (5mL) alone in a 100mL mixture)?
Option 1 Answer: This is a hard one as it really would depend on the 3 flavors. For example, a Menthol at 5% alone might be tasty, but mixed with something else, it would require to be "turned down" a bit. If this is what you are looking at, I suggest searching for some recipes or doing some trial and error, as this has quite a few variables as far as flavor is concerned

Option #2: Or are they in mixture with eachother (5% Flavor 1, 7% Flavor 2, 12% Flavor 3).
Option #2 Answer: This is relative simple to do. What I always do it equate this to a 100mL mixture and work from there;Soooo:

Flavor #1 @ 5%: 5%/100= 0.05; which means that this would be 5mL our of a 100mL mixture; thus giving your ratio number (to multiply by any desired overall volume) of 0.05
Flavor #2 @ 7%: 7%/100= 0.07; which means that this would be 7mL our of a 100mL mixture; thus giving your ratio number (to multiply by any desired overall volume) of 0.07
Flavor #3 @ 12%: 12%/100= 0.12; which means that this would be 12mL our of a 100mL mixture; thus giving your ratio number (to multiply by any desired overall volume) of 0.12

Example: 120mL Solution with this flavor concentration:

Flavor #1; 120mL x 0.05= 6mL
Flavor #2; 120mL x 0.07= 8.4mL
Flavor #3; 120mL x 0.12= 14.4mL

Let me know if that answered your question....

well jeff (the calculation master), see if you can figure this out. a couple people have tried but I'm a math failure. Appreciate the offer to help.

Let's say I have three flavors that I tested out as individual flavors at these percentages (like your example of 6% TFA Cinnamon), Flavor #1 @ 5%, Flavor #2 @ 7%, and Flavor #3 @ 12%. Now I want to mix these together to create a recipe. I found that I like the combination of of 1.5 ml of flavor #1, 2.5ml of flavor #2 and 1ml of flavor #3 in a 5ml bottle.

what's the calculation to determine what percentage I need of each flavor to make larger bottles from scratch?

I am not totally understanding the question if you have those mixed in a 5mL bottle or concentrate... Please clarify

Ahh, I got it...

Unfortunately there is no easy way to calculate how much to add as there is no saying the exact percentages (at what flavor strength) the company you bought it from put in to each of those.

This would fall under more of a mix to taste for the first run, then use those ratios in subsequent runs. I usually do test runs in about 5-10mL batches.

Sorry I couldnt help you more, but mixing is overall pretty damn fun, so I am sure you will enjoy it!

This is way easier if you just download one of the excel based calculators posted in the sticky threads of this sub-forum
