Nicotine base?

[bcollier9253]

This is what I ordered. 100mg Nicotine solution - 250ml
Item# NS-100MG-250ML , Carrier Base Liquid: 100% USP Propylene G.. So now Do I need to do any further diluting? Or let the calculator figure it out?

I got the nic from WL if that matters

The calculator would figure that out or it's 10% nic. If 16 mg is needed on the final mix. That would be 1.6 ml to a 10 ml bottle of juice. Diluting the 100 mg would slow down the oxidation process. I rarely do it, but had nic bases of mine get pretty nasty. Oxidized nic does not work great with non tobacco flavors.

Thanks Jimi! If I decided to cut in down to let's say to 50mg/ml I would add another 250ml of pg or VG correct? And in doing so, wouldn't that increase the amount of pg in the base if I cut it with pg and possibly be to much for the final50/50 mix at the end? If cut with VG I wouldn't need to add VG at the end would I? Would I then enter into the calculator for the base,50mg 200% pg if cut again with pg since it's already been cut with 100% pg and if cut with VG I would enter 50mg 100%vg? Sorry for such newb questions, just trying to make sure I got this

if you cut the first 250ml 100mg with 250ml pg you would have 500ml 50mg if you cut that with vg you end up with 1000ml of 50/50 pg/vg 25mg

 

[bcollier9253]

if you cut the first 250ml 100mg with 250ml pg you would have 500ml 50mg if you cut that with vg you end up with 1000ml of 50/50 pg/vg 25mg

Okay, the stuff I ordered was 250ml of 100mg/already with 100%pg. so if I cut it again with 100% pg that makes 500 ml of 50mg, I get that. What I dont get is when I enter into the calculator I would enter 50mg and 200% right? And if so, would'nt that make my mix target of 50pg/50vg not work out?

 

[bcollier9253]

Let me ask if this is right: I take the 250ml of 100mg/100%pg and cut it with 250ml of VG I would end up with 500 ml of 50mg 50Pg/50VG??

 

[Hoosier]

250ml * 100mg/ml = 25000mg
250ml of PG + 250ml of VG = 500ml of 50/50
25000mg / 500ml = 50mg/ml


Knowing that "mg" is poor shorthand for mg/ml makes the math more apparent.

 

[bcollier9253]

250ml * 100mg/ml = 25000mg
250ml of PG + 250ml of VG = 500ml of 50/50
25000mg / 500ml = 50mg/ml
Knowing that "mg" is poor shorthand for mg/ml makes the math more apparent.

I guess the pg that the original juice is made with is what is confusing me. From what I gather from your math, is your telling me to add another 250ml of each(pg&vg) to get a 50/50 but what about the original pg in the juice? Isn't what your telling me making the final juice have more pg and not 50/50?

 

[bcollier9253]

Or do I just forget about the original pg used as a carrier when I start to dilute? (Take it out of the equation)

Yes

No

Adding 250ml of VG to 250ml of 100mg PG will result in 500ml of 50mg with 50% PG and 50% VG. There are two separate formulas in play to validate this:

Nicotine formula:
1. You have 250ml of 100mg nicotine (100mg per ml of liquid). The total nicotine is 250 * 100 = 25000.
2. You are adding another 250ml of liquid (VG) which contains no nicotine giving you a total of 500ml which contains 25000mg of nicotine.
3. Calculate the resulting nicotine level per ml by dividing your total nicotine by your total ml. 25000 / 500 = 50. 50mg/ml.

PG/VG formula:
1. You have 250ml of PG and 250ml of VG. The sum is 500ml.
2. The PG% is 250/500. The VG% is 250/500.
3. Resulting in 50% PG and 50% VG.

Thanks guys! It's been awhile since I've tried algebra but I think I finally got it through my thick .... head! Okay, with that out of the way, that final dilution can be used in the calculator as 50mg,50%pg/50%vg. and I can derive 12,18,24mg targets with 50/50,60:40,70/30 pg/vg and not have the calculator show any negative amounts of pg or vg in the final recipe. I guess what I'm asking is the 50mg50/50 a happy medium base to start with?

Pretty much, but keep in mind your flavoring is mostly PG also. So if you start with a 50mg 50/50 mix (PG/VG) and want to cut it to say 25mg the most you can get will be 75/25 in either direction depending on if you cut it with VG or PG.

Example 10ml of 50/50 mix cut with 10ml of PG would give you 20ml of 25mg NIc at 75% PG and 25% VG. Now don't forget in your calculator the flavor will also be counted in PG (unless you get flavoring in VG)

IMPORTANT What you really need to ask yourself is what final percentage of VG to PG do you want your E-Juice to be and what do you want your Nic mg to be.

PS I use E Juice me up - If you haven't already done so, download it and put in different numbers to see what is and isn't possible (Hope that makes sense)

Yes it does make sense. I have already played with E-juiceMEup, that is why I said"showing negative amounts" hence the reason I have been so diligent in trying to get an answer on the dilution. All of y'all's replies have helped tremendously!, Many thanks to all! I got some of my flavors in yesterday, more to come fromTFA and still waiting on nic from WL, pg/vg from essential depot. Oh yeah, bottles are in route as well. Already got my graduated cylinders and beakers in vape mail. Getting closer! Thanks again guys!

I was answering a question that only had 250ml of PG and 250ml of VG. I have no idea what the "original" PG is since it wasn't part of the question.

I included all the liquids, 2, in the math that were included in the question.

It was so the math can be seen and applied to whatever you want.

Multiply the mg/ml by ml to get total mg
Add ml's together to get total ml and ratio
Divide total mg by total ml to get final mg/ml

 

[bcollier9253]

Thanks Hoosier! The original pg I spoke of is what is in the nic when I buy it, ie: 250ml-100mg/100%pg. It makes sense to me now, I am to look at the nic purchased as 250ml of pg with 100mg per ml of liquid

 

[erinarthur222]

36 mg 50/50 pg /vg base ... my target nico level is at 4 mg now !!wooohooo. i get it from ecig express
