I guess that I might have been wise to hold back the Vinegar from my “Free Range Non-GMO Corned Beef Shanks” sauce. Just wanted to “marinate the meat” (so to speak). Much better bovine “bouquet” that way.

The Acetate salt appears to be a fairly common formulation of (the various) Vitamin E molecules (up front).
Acetic Acid is item number one on this list of “can be used” acids for Nicotine Salt formulations. Who knew ?
I guess that would be the difference between a process and an additive. That stuff will literally make your sinus’ bleed.
I can dig it. Similarly, Hydrochloric Acid, Sulphuric Acid, Citric Acid (and other common ones widely used in medicinal salt formulations) are not desirable to play with (in any appreciable quantities, whether complexed as a salt in solution, or not) where it comes to one’s internal mucus-membranes - which can be quite finicky.
The FDA places Acetic Acid on their recent proposed list of Respiratory Toxicants (RT) appearing below:
Right on cue, the administration is rolling out it’s most erudite intellectual heavyweights on scientific matters:
It will likely be hard to argue with the gravity of such highly influential thinkers of our time in the White House.

This “breaking news” article puts new a twist on and gives a new meaning to the saying “Katy, bar the door!”:
“Vaping fears prompt Alabama high school to remove bathroom stall doors”
You gotta love corrupt organizations like CDC and WHO that knowingly want to spread misinformation about vaping
and to think… reps from the cdc has to be present in some labs to inspect the flavors being made…
For Vaping… 
URINE TESTS !!! indeed not heard one case of this simple method… 
This looks like interesting information (indicating that certain Vitamin E Acetate additions were intentional):
(Leafly; September 6, 2019): “Vape Cart Additive Makers Pull Products as Others Go Dark”
Clear Cut contains vitamin E acetate. Jones confirmed in a letter to Leafly that Clear Cut contained tocopheryl-acetate. Jones wrote Leafly that he had permission to use it from the Oregon Liquor Control Commission and thought it was safe. … The popular illicit market diluent thickener Honey Cut, based out of Los Angeles, may contain vitamin E oil, according to independent tests …

(Leafly; September 9, 2019): “Vape Pen Lung Disease Has Insiders Eyeing Misuse of New Additives”
Industry insiders who track the legal and illegal vape cart markets closely tell Leafly that a new type of additive started showing up in late 2018, and has since become widely used in underground markets. It’s a novel class of odorless, tasteless thickening agents. These liquids come in different proprietary formulations manufactured by both legal, above-board companies and by shadowy underground operations. This new additive may or may not play a role in the current health crisis. But it is one of the major new ingredients in illegal vape cart oil in widespread use this summer.
I do believe so too…

For the curious (regarding Vitamin E related substances, and Acetate Salts):

oh, come on. as you pointed out yourself, glycerol and PG are also on the list.
Maybe you guys guys can start your own quiet little thread about the dangers of putting acetic acid or citric acic in your juice?. I’d be seriously seriously intersted to know if there’s any real concern here, given that some of us do talk of adding vinegar, lemon . or commercial “sour”" to our juice.
Suspect you’re just taking the piss, in fact. But you’re so freaking deadpan it’s hard to be sure.
Hi Jay, Harlan and I were having a rational discussion there - no parental guidance needed or desired. 
nothing to do with parental guidance. If you’re seriously suggesting i should throw away my natural lemon extract, if i don’t want my lungs to suffer, then i want that discussion out there in it’s own thread, where i can read it at my leisure, not conflated with all this gubbins. But, what the heck, that’s a pretty big “if” methinks.
At your (de-conflated) leisure, your non-parental guidance:
Jay, Lemons contain Citric Acid and some Ascorbic Acid (Vitamin C). Little or no Acetic Acid (in Vinegar).
Thanks for the basic chemistry lesson, Mr Raven, Sir. But the the thing is, I could swear that you also mentioned citric acid as one of the substances that could react with palm oil (or residues of oil in palm-based glycerol, or something like that) , to grim effect?
What is funny about all of that, when I stopped smoking and started vaping, my chronic bronchitis that I would get for years on end, went away. I have not had bronchitis in 9 years, coincidentally that is when I started vaping.
Jay, I (above) reported reading that Palm Oil contains a fair amount of Tocopherol(s) (various molecules know collectively as Vitamin E), and wondered if perhaps (low quality) Glycerol (might, possibly) retain some of that. From there, Tocpherol(s) Acetate would be be formed in solution by the addition of (small) amounts of Acetic Acid. None of which likely has one nitty whit to do with the chemistry of your favorite “citrus fix” …
… but fear not, I have some cautionary tales regarding the (predominant?) Citric Acid of your Lemon Craze:
… 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 *C).
Higher temps may decompose Aconitic Acid to Methyl Maleic Anhydride (“not for flavor or fragrance use”).
