Juice ingredients query..?

OK I understand say, 18mg is 18mg of nicotine suspended in each millilitre of liquid in a bottle - but anywhere I've seen this as a percentage it has been 1.8% nicotine. The same for 12mg=1.2%... 24mg=2.4% etc.

For this to be the case the density of the nicotine will always have to be the same ratio to the density of the e-liquid it is within (i.e. 12=1.2% 24=2.4) - but few liquids have the same density! They all vary due to PG/VG ratio.

I know that 1 gram of water equals one millilitre of water. But turning the density (1g) into a volume (1ml) only works for water 1:1. PG and VG are denser. Would that relevant?

So if a 12mg bottle of 50VG/50PG was indeed 1.2% nicotine, would an 12mg bottle of 80VG/20PG not have a % nic less than 1.2%?

Am I missing something (or being dense myself)? Thanks.

 

[dcfluegel]

typically, nicotine is suspended in a base of PG or VG or a blend of the two, so the percentage remains applicable to the ratio, density wise

1.2 nic is 1.2 nic. Regardless of the VG/pg ratio....

That's very true. But say you'd 2x100ml of 18mg (in either PG or VG base would not matter) if you added..

(A) 100 ml of just PG.. and to the other

(B) 100ml of just VG...

you have 2x200 ml of 9mg, but bottle (B) is now heavier than (A) and the nicotine % couldn't be the same for each if the % nic is taken as either weight or density - yes?

Thanks wondering for label regs in UK to show % and weight of everything.

normally its considered % per volume, not by weight... or, mg/ml ( nic/base)
one could mix up 18 mg of nic ( pure) with water, Hersheys syrup, gasoline ( to equal a volume of 1 ml when mixed) its still gonna be 18 nic "fluid"

and please folks... dont even consider doing what I mentioned... Hersheys syrup will trash your coil, and gasoline just tastes really nasty and will make you sicker than a nic OD

 

[steam heat]

Regardless of the mix the nic stays the same..VG/pg ratio does not have anything to do with the nic content...I can't think of a better way to explain it

 

[Bunnykiller]

as far as the mg/ml vs. %... nic weighs in at 999.97 mg/ml, close enuf to call it 1000mg/ml and 18 mg is 1.8% of 1000
alot of people get confoozed over this point ... guess they want to think nic is at 100mg/ml leading them to think 18 nic is 18% or even 1.8% should be 1.8 nic

think of it this way... you place 18 pennies into a coffie cup and then fill it with water, you place 18 pennies into another coffie cup and fill it with mercury... the cup with water is going to be alot lighter than the mercury filled cup, but both cups have the same amount of pennies in each... thus the weight of the pennies in each cup will be equal.

 

[steam heat]

That was the best way to explain it!

 

[VapexTwin]

Ok pennies expressed as a percentage volume in each cup there would be the same. Each cup has a different total weight - yet has the same amount of pennies.

The Nic (in any solution) will then take up a % of the volume, the same as pennies would.

Saying 18mg=1.8% nicotine holds true then - but the weight of the other 98.2% does not matter.

I think I'm no longer confoozed. Thank you all.

Yup you got it now! And glad we could help ya out with that

+1 to @Bunnykiller If you have a 30ml bottle of juice, and it's 1.8% nic, then it's 1.8% no matter what else is in the bottle. Similarly by milligram: 18 mg/ml is 540 mg of nic in a 30ml bottle, no matter what.

 

[VapexTwin]

and if I made a 100ml 16mg/ml bottle and divided that up, each bottle would still be 16 mg and 1.6% nic. Makes sense now. It was the weight in mg had me pickled.

(btw up to tonight I always thought nic level on side of cig packets was per packet. It's per cig. Smoked 25 years duh.)

Thank y'all kindly really quick and helpful

This exactly, which is why I'll never "get" mixing by weight -- I don't buy 10 lbs of milk, or a gallon of bacon. You measure liquids with liquid measures; you measure solids and dry powders by weight and/or dry volume. I mean.. DUH!
