Is it OK to make premixed ingredients in large batches and later add them to VG/PG/NIC?
submitted over 10 years ago by neonstereo

Hello,

I've got a small ejuice company and realised that the logistics of making juice is a bit overwhelming and I'd like to streamline my process.

Is it possible/ok to premix my ingredients (flavor concentrates) at the right ratios in a large batch and when orders come in, add them to PG/VG/NIC?

i.e. say I have a mixture which is 5% strawberry, 5% watermelon, 5% raspberry ..

can I make 1500ml, with 500ml of each ingredient and then when orders come in and I have to make, say a 100ml bottle.. add 15ml of my base and then 75% of diluting liquid?

I hope this make sense..

Thanks!

yes it's fine.

but i warn you. shake the actual SHIT out of it before using it ever.

Yeah, that's pretty much good advice for single flavors too. Shit can settle.

Shit really? Like a single vial of just flavoring? Shake it before adding it to anything?

Yeah, I shake anything I'm about to add to my mix. Nicotine and flavorings. I've seen some of them settle if sitting for a long time. Just want to make sure I get accurate amounts in every batch.

Yes you can!

That's going to be the way I do it also when I get my recipes finalized.

Here in Australia things are a bit simpler because we can't sell nicotine in our juice. Vendors here sell singlers or doublers - which is double strength flavouring (your example in doubler form would be 30 percent flavouring and 20 percent PG/VG). The idea being much like cordial, the consumer can top up their mix with 12mg nicotine base to get a final 6mg content.

Rather than just flavours, I found it easier to premix doubler solution so I don't need to worry about each individual recipe percentage.

A bit off topic.. But I really wish more USA premium juice vendors had doublers as a wholesale option so we could stock them here locally.

So I guess another option would be for you to have a nicotine base which is double the mg of each of the strengths you're selling and a doubler solution of each of your flavours.. That way, you also won't have to worry about flavour percentages. Will all just be 50 percent of your doubler.

I'm actually based in oz too

I wanted to make my base ingredient mix without makingn then as a doubler for now because te scales that I use can only go upto 500grams, and when you add the weight of the beaker etc really were talking about making 12 bottles at a time.

Since I have 5 flavours, that becomes quite time consuming by the time you add in labelling and shipment so I'm hoping to make 20-30 bottles worth at a time ideally.

Do they not understand how that law is going to hurt/kill poeple for no good reason?

I hate protectionist bullshit. Specially for something unstoppable like ejuice. There is really no way they can prevent people from getting ejuice. They could make nicotine illegal I guess but that will just open up a very lucrative black market that will end up hurting/killing even more people.

I just asked this question on another post, im guessing the consensus is yes.

You got a lot more replies than I did, your post helped me out more than my own.

Consensus seems to be a good idea, I just posted about something similar and people are recommending this as a way to mix... seems easier

Fun fact: this is how soda pop is made. Top secret concentrates are shipped to bottling facilities which add water, sweetener, and bubbles.

that is indeed a fun fact!

I was always under the impression that pre-mixing flavor concentrates was not advised. Something to do with the different pH levels of the flavors and causing flavors to end up muddled. We create a base of PG, VG and Nicotine first before adding flavoring.

Another shop in town mixes up say 1000ml of 32mg strength liquid of flavor A. Then another batch of 1000ml 0mg strength liquid of flavor A as well and the. Dilute the 32mg with the 0 as needed.

THIS.. . i'm interested to know if anyone has any more info on stuff like the PH levels issue /u/adamfear is talking about.

OK. Let me just throw this out there for you. When you mix different flavors, you already have a cocktail of chemicals that can react, either adding to, subtracting from the flavor.

Let us look at what is in Black Currant alone:

https://shop.perfumersapprentice.com/componentlist.aspx?sku_search=346718

> 3-Hexen-1-ol, (Z)-

> Butanoic acid, 2-methyl-, ethyl ester

> Decalactone <gamma->

> Cinnamate <(E)-, methyl->

Now you are going to mix that in with another flavor, or two or three. Do you know how those are going to interact over time? I personally can not predict that off the top of my head. There should be a way to make educated guesses about some of them. But it should be difficult to know for sure what all of them will do.

As someone mentioned above, if you have a high acid PH flavor and a high base PH flavor, you can be sure there will be some chemical interactions going on.

Perhaps the best thing to do is to try it with a small batch of flavor, and then compare that with a fresh batch over time to see if/how it affect the flavor.

This scientific way of looking at it is wonderful, thank you!

I will,try with a small batch and leave it for 4 weeks. I'll try and fill a bottle up to the point where oxygen interaction is at a minimum.

I can't remember where I read that bit of information, but have been following it since the beginning of mixing my own liquid.

I worked in hydroponics before and not mixing flavoring in first kinda makes sense. considering that in hydroponics certain chemicals couldn't be added until you had enough water in the system first. Otherwise insoluble solutions could occur

So I just play it safe and add nicotine and PG first for my base. Then add flavoring and the VG last. I used to add flavoring at the very end, but found it mixes faster in a magnetic mixer adding the VG at the very end.

Whether you premix flavorings or mix straight into a bottle your results will be close enough that it shouldn't matter. Most of the reaction with flavorings happens when you add the nic.

Yes and it makes things so much easier
