So you’ve got yourself a nice Personal Vaporizer. And you’ve tried all the flavors of E-liquid you can find, and none of them satisfy. It seems that you shall have to mix the E-liquid yourself to get the flavor you want. But how to do it?
To start with, you must know that the information contained within this article, while written to the best of our research, must still be taken with a grain of salt. As we are dealing with a DIY for liquids intended for inhalation, there is the potential for things to go wrong. Be sure to check more resources than just me so you can ensure your safety.
Now, with that disclaimer out of the way, let us examine the basic ingredients of E-liquid, or “Juice” as it’s commonly called these days. The basic ingredients are: Propylene Glycol, Vegetable Glycerine, flavor concentrates and liquid nicotine. Some people also add vodka or pure grain alcohol as a means of diluting the E-liquid itself, but that is an after-the-fact issue. Before you have the chance to dilute your E-liquid, you must mix it first.
Your basic tools for mixing E-liquid are:
1. A measuring cup or graduated cylinder;
2. A pipette, eyedropper, or plastic syringe with a blunt needle;
3. A small funnel;
4. empty 10ml/20ml bottles;
5. latex gloves.
Put your latex gloves on. You don’t want to get nicotine juice on your hands.
Now, the amount of E-juice that fits into your vape device is typically 10ml. As such, ratios and millilitre measurements as displayed on E-liquid calculators are typically based on the notion that you’re only measuring 10ml of E-liquid at a time. maybe you’re working bigger. For now, we will base our calculations on a total volume of 10ml.
The ratio of nicotine juice to Propylene Gycerol and Vegetable Glycerol varies depending on how strong you want your hit to be, and upon how strong the nicotine juice already is, because it comes in varieties: 36mg, 54mg, 72mg, etc. (“mg” refers to milligrams per millilitre. Nicotine juice is never stronger than 100 mg.) But let’s say you’re looking for a low-strength hit using the 54 mg juice. let’s say you wanted a hit that was equivalent to a strength of 8mg of nicotine juice. You would take a clean little 10ml or 20ml bottle, and with your pipette, add 1.5ml of the nicotine base, 3.25ml of the PG, 3.25ml of the VG, and 2ml of flavor concentrate. Whereas if you wanted a 27mg hit, you would mix 5ml of nicotine juice, 1.5ml of PG, 1.5ml of VG, and 2ml of flavor concentrate. The ratios vary, the total amount of liquid stays the same at 10ml.
That gives you the basic idea of what we’re dealing with here: relatively small amounts of liquid to fiddle between. You could, I suppose, mix up whole litre of liquid and use it up real slowly, but that raises the question of how to store it without your roommate mistaking it for vodka. It’s probably better to mix a max of 30ml at one time to minimise waste and keep storage options more open.
Or I suppose you could mix up a litre and then apportion it into 100 x 10ml bottles. If you’ve hit upon the perfect flavor to the extent that you’re willing to mix up an entire litre of it.
Now, the numbers I have provided above are not as exact as what an online mixing calculator will tell you. For example, on EcigVape.com’s mixing calculator, they say that the proper concentration of nicotine juice for an 8mg-strength solution is 1.4815 ml, or 29.63 drops from the pipette.
If you can find yourself a pipette or a syringe that measures liquid that precisely it will come in handy depending on how you measure out your flavor concentrates. The total amount of flavor concentrate shouldn’t get above 2ml. So if you’re trying to mix two flavors, that’s 1ml per flavor; if you’re trying to mix ten different flavors, you’d use 0.2ml of each concentrate. That’s if you WANT your flavouring to be 20% of the e-liquid’s volume. You’re probably starting out with a low concentration of flavor, like 5% of the volume, in order to test the taste and get used to it. so having ten flavors in 0.5ml of flavor concentrate would mean you used 0.05ml for each flavor
I don’t really know how anyone manages to work with liquid volumes that small, but the calculator on EcigVape.com assumes it’s possible.
As for the ratio of Propylene Glycerol to Vegetable Glycerine, it does not have to be 50/50. Sometimes it’s 80/20, because people prefer the thinness of the PG over the thickness of the VG, and they’re looking for a heavy throat hit. Some people prefer a lighter throat hit, and they add a higher amount of VG than PG. Some people are allergic to PG, so they have to use all VG, and THAT’s where the vodka comes in, because VG alone is almost too thick to use. Vodka and pure grain alcohol can replace the throat hit that would be missing without the PG. Don’t add it in the same ratio as PG, though — keep it at a range of 1% to 5% of the volume.
Whenever you’ve managed to make your solution, in whatever concentration, make sure to shake the bottle thoroughly before you put your E-liquid into your vape device. Also, write down whatever recipe you used, in case you discover that you enjoy the flavor you’ll need to consult your recipe if you want that flavor again.
Lastly, it is recommended that any juice that you mix is left in a cool dark place for at least 2 weeks, this is called ‘steeping’. This allows for the flavour concentrates to permeate the PG and VG and round out the flavours overall. For some recipes you will see that they are described as being “shake and vape”, these recipes can be consumed as soon as their mixed, however even these will likely benefit from a 2 week steep.
Happy vaping and good luck.
