Once you apply for a patent it becomes public knowledge, that’s how patents work, how could you know if you where violating a patent if you couldn’t see if someone had already created something. That’s why allot of trade secrets are not patented. That way they can keep them secret.

Look up any patients you want right here on the us patent office site.

Sounds logical now. I guess I didn’t think this question thru before asking it.

Yes I have made my own salts - salicylic acid salts are much better when done with pure nic (i don’t recommend it). Benzoic acid is pretty easy - I posted the ratio somewhere here about a year or so back but cant put my finger on it (i used a little less than the doc said) but it isn’t important since it is in the doc you posted 380mg benzoic acid to every 500mg of nic

Here are 2 screen shots …1st one explains making a benzoic acid solution and the second how to mix at correct ratio for the salts…
This was taken from an old vaping underground thread. I’ve been researching this because i’m seriously interested in trying it. The salt nic is made here using 100mg/ml freebase.
Seems daft to buy it when most of us have a freezer full of freebase

Does Benzoic acid give off a taste? Every Juul flavor I tried gave off a similar taste. It’s pretty apparent in the Cool Cucumber and mint pods because they are light flavors… It’s not a bad taste. Just wondering if Benzoic acid is responsible it.
Also after skimming that patent, it looks like Juul tested out +10 acids, I wonder why they chose Benzoic Acid… Hmm…

There has been some suggestion that juul uses a mixture of method for their salt nic. The assumption would be that there are slightly differing factors according to the acid used to make the change…differences in absorption for example.
To answer your question yes it is the acid used which changes the flavour or imparts a new flavour. I’m no expert here though i’m just relating what i have read during my research. :)

I don’t know if you might have come across this sub already, but maybe it could contain some useful information about making your own salts. If not disregard my post.

I hadn’t…I’ve had a quick browse and it seems to confirm what I knew already but interesting all the same thanks 
It’s certainly an interesting subject though and i’m definitely going to try out the process. Ultimately it would be nice to lower lung intake whilst still getting a good nicotine hit.

I saw a statement about benzoic acid apparently it was chosen by Juul because of the amount of time it took to cross into the blood and reach the brain - it was significantly less than other acids and closest to analogues that they found.

Thanks…yes I needed this confirmed. I had heard that the juul patent used a mixture of different acids to create a result that hit the blood brain barrier even quicker. It’s nice to know that the major player here is tthe benzoic acid though.

That graph is epic . Always knew that cigarettes packed a punch compared to freebase liquid nic but wow

Ok so i’ve ordered the benzoic acid and will make the salts as soon as I receive it. I’ll probably start a new thread to report back. Delivery estimates are around 3 weeks but its only coming from Poland to France so i’m expecting it a bit sooner.

Could you tell me the name of the company?

The seller is named chempl and is on ebay. He is based in Poland. Hope this helps.

@woftam just reviewing this and wondering if you could let me have the source. There are some similar graph’s in the patent doc but they’re difficult to read. Specifically I am interested in the explanation for the Pax labs ‘tested’ as against ‘commercial’.
Thanks in advance.

@woftam I think I may have found the source via another thread…here it is…

You’re welcome…by the way ebay is a good source. There are lots of different vendors selling the Ba…UK, USA, etc. I chose poland because it was nearest to me.

Thanks for the reference to PAX’s 2015 patent !
So much for my occasional fantasy of grabbing a few granules of the Citric Acid powder that I use to make “poor man’s Limeade” sweetened by Sucralose, and dropping them into my mix. Here’s why that is the case:
“The suitable acid for the nicotine salt formulation does not decompose at the operating temperature of the electronic cigarette.”
“… citric acid decomposes at 175°C … thus for a device operating at 200° C, … may not be appropriate.”
The human body itself internally manufactures around 5 Pounds of Citric Acid daily (as part of the biological Kreb’s cycle). When ingesting Citric Acid into one’s stomach, aside from (potentially) being a bit rough on tooth enamel in higher concentrations to due acidity in general, it readily decomposes in (more) acidic stomach fluids (where pH ~3). No big deal with that - I add it to my drinking water (with Sucralose added for sweetening) all day, every day. Elimination of bodily citrates via the Kidneys is important to prevent stones.
However, starting at around temperatures of 150 Deg C, and more significantly at 175 Deg C, it dehydrates (losing Water), and decomposes into Aconitic Acid. There are two isomers of Aconitic Acid (AA) - trans-AA (having a melting point of 194-195 Deg C), and cis-AA (having a much lower melting point of 122 Deg C). This means (when vaporzation temperature is below 195 Deg C) that decomposed Citric Acid will result in little solid chunks of trans-AA floating around in one’s Nicotine salt e-juice. Sort of sounds like a bad idea ?
Aconitic Acid is sometimes utilized as a flavoring agent: trans-AA (“nut, vegetable, caramel”); Cis-AA (“wine acid”) - so one would expect a (Citric Acid formulated) salt of Nicotine to alter e-juice “flavor profiles” as a function of vaporization temperatures (when between the two differing melting points of 122 and 195 Deg C).
Higher temps may decompose Aconitic Acid to Methyl Maleic Anhydride (“not for flavor or fragrance use”).
.
All that it takes to convert (the alternative) Benzoic Acid (used by PAX in JUUL Pods) to the extremely dangerous toxin Benzene is decarboxylization. See: “Benzene formation in electronic cigarettes”.
