Is Nicotine % Calculated Before Adding Flavorings?

[YoMajesty]

Hi,

DIY question. When a company says its ejuice has an 18mg nicotine level, and the percentage is 1.8%, does that mean that nicotine is 1.8% of the PG/VG/Nic mix (without the flavor) rather than 1.8% of the whole batch?

For example: I have a 30ml bottle with an 18mg nic mix of PG and VG that takes up 22.5ml (75%). The flavorings total 25% of the total 30ml. Is my juice still 18mg, or is it closer to 14?

I'm just beginning DIY with unflavored premixed juice. And yes, I'm aiming high with the flavoring volume. Most commercial vape juice flavors are too subtle for my tastes.

Working on perfecting a mad scientist formula called Hot Creamy Fruit Orgy, powered by FlavourArt. Once it's perfected, I'll have my trusty assistant, Igor, post the recipe somewhere.

Thanks,

Me

Hi,

Nicotine is measured in milligrams per millilitre. Pure nicotine is 1000mg/ml.

In your 30ml bottle, EACH ml contains 18mg of nicotine. So your bottle contains: 30 X 18 = 540mg of nicotine.

Your example: If you started with 30ml of 18mg/ml and then ADD flavouring at 25% (7.5ml), your end result would be 37.5ml of 14.4mg/ml strength juice. (Note: STILL 540mg of nicotine in the bottle)

Which eliquid calculator are you using?

Thanks. Ouch. In my example, that would be 405mg of total nicotine. Divide that by 30, and I get a total strength of 13.5mg/ml juice. That sucks. I should have bought the 24mg premix.

Anyway, I figured out how to raise it. I need to start with 1.75ml of 100mg juice, and then add the other pg/pv/nic mix until the total becomes 22.5ml. After adding the flavor to fill the 30ml bottle, the total strength should be about 18mg/ml. It'll just be a few days before I get the 100mg stuff. I can deal with a weak batch until then.

Estimation is unnecessary.

Thanks. Someone else recommended that calculator too. Not suitable for this project. When starting from scratch, it could come in handy. This is a complex mistake fix. Just ordered 36mg unflavored because it's USPS legal for shipping. That'll raise the nic levels a notch. Luckily, my degree's in math. I'm just rusty and haven't studied math since 1999. Still have some wits for basic chemistry systems of linear equations with a few ums and ahs and oh .... I done screwed ups during the calculation process.

...I beg to differ.
EJMU is absolutely suitable for this project.

Nice. I'll download it. I'm actually going to throw in 2 extra ml of VG as well. Future batches are likely to come out to 16mg/ml nicotine. I can live with that.

I use the online calculator for reasons like no installation and accessible from wherever I am at the time plus the ability to share and save.

Did something change? All my 100mg/ml nic was shipped USPS.

As far as I know, nothing has changed.

Probably. 60mg and up is UPS Ground only, apparently. It might be 65+. It's some weird law that could be recent.

Nicotine River seems to be the only company with this requirement so far.

I first got that message in ecigexpress.com's shopping cart. I researched it, and another company stated this regulation in its shipping FAQ's. It even said that many flavors are banned. Google it and see what you find. I searched for "100mg nicotine ups ground only".
