A Formulation Question

I probably Fat-Fingered something Important alone the way.

From my days of using Flavored DIY, I can tell you that it is Much Easier. So here is a Solution that Satisfies those Two Equations for mg/m and for PG to VG Ratio.

To make a "Pre-Mix"...

Now to make a 15% Flavored Final 25mg/ml e-liquid @ 50%PG to 50%VG...

OK so above is a Unique Solution for those Two Simultaneous Equations. And will work Fine as long as we are making 100ml at each step. But we would like a General Solutions for any given Unit Amount.

Hence it would be Better if we Worked in Percentages and Not Milliliters. Because a Percentage is a Unitless Measurement.

So I look at what I need to do to make 100ml of "Pre-Mix" in the Top Screenshot. But notice since I choose 100ml as my Total Amount, can't I consider the amounts of the Nicotine Base, PG and VG to be used as Percentages?

Hence my "Pre-Mix" Recipe becomes use 78.95% 38mg/ml 50|50 Nicotine Base and 20.23% VG and 0.83% PG. This will give me a Pre-Mix that is 30mg/ml @ 40%PG | 60%VG.

To make my Final Flavored Mix, I can consider the ml's to be Percentages also since the Total was 100ml again. The 2nd Screenshot says to use 83.33% Pre-Mix and 15% PG Based Flavoring(s) and some Trace amounts of VG and PG (0.25% and 1.42% respectively) to make an Exact 25mg/ml 50|50.

Now comes a Nifty use of Tolerance. What would happen if I Didn't add any more PG or VG? And just used the Pre-Mix and the 15% Flavoring? How much would it be Off?

Since the Total Percentage of PG and VG to be Added in Less than 2%, wouldn't my Final Mix be Off be Less than 2%? But the Real Question becomes am I going to be able to Tell the Difference if I didn't know it was there? Like when one buys Retail Pre-Made e-liquids.

You're really Not. So It's Miller Time! And we are Done! So there you go.

Make 30mg/ml Pre-Mix using the Above Formula.

The Mix 85% Pre-Mix with 15% PG Based Flavoring an La Vola, you'll ready to vape on some Mouth Watering 25mg/ml 50|50.

Once again... Print this out and have someone Double Check my Math/Typing. I probably Fat-Fingered something Important alone the way.

This is extremely useful, thank you for taking the time to do all this and explain it along the way. You should be in education. I'm going to implement this immediately.

Thanks again

Just see'n who is on their toes after that Novelette I wrote.

That's Funny. Because I'm retired after teaching Part-Time in Math and Manufacturing Technologies.

And as with All Advise DIY-wise, do a Small 50 or 60ml Test Batch before you commit to something larger.
