Hi I recently noticed that when I thought my coil was finished but I put a juice with 5% TPA strawberry that I was able to use that coil for a few more days and think it’s the Triethyl citrate emulsifier that is key here.
Does anyone know of more consentrates that emulsify? Here are the one I am currently aware of.
FA “Almost all, as we use triacetin as base carrier for our concentrated bases then diluted to make fina flavor.
Triacetin % in final flavor can range from 1-8% roughly”
Below are alot of the off-shoots or branch molecules of what your looking at >“Triethyl citrate”< - It’s a long List
Not sure if any of the off-shoots are used in TPA flavoring but it’s a start. You can look up their Cas# at TheGoodScentsCompany site and pop it into TPA’s list like you did below.
Opps it won’t put the results. Just pop in “Triethyl citrate” where it says (Name within name) and it will generate a long list.
Here are other names for it…
CAS 77-93-0
Triethyl citrate, 99%
Estimated Decomposition Temperature of Triethyl Citrate is around (and higher than) 200 *C. Hazardous decomposition products: Thermal decomposition can lead to release of irritating gases and vapors. Physical and Chemical Properties, Page 3
When Triethyl Citrate decomposes due to hydrolysis (in the presence of Water), the resultant products are Citric Acid (1 mol) and Ethanol (3 mol). These chemicals are also the primary endogenous metabolites (resulting when Triethyl Citrate is absorbed into the human body), and neither of them are particularly toxic.
(Perhaps) some Triethyl Citrate (near the coil-wick interface) is decomposing (in part) to Ethanol, giving the coil-gunk a “bit of a wash” in a solvent in which it is partially soluble - with the (possible ?) consequence of sending some of the resultant “flooby-dust” (perhaps safer burned-off instead) up into the inhaled vapors.
I am saying that … perhaps … some … of the coil-gunk (caramelized sugars, and/or their decomposition products) makes it into vapor - and/or gunks the coils, and/or collects and builds-up in the wicking material. When I have applied a bit of Ethanol to SS 316L coil-gunk (together with a metal file), some of the built-up coil-gunk is indeed soluble in the Ethanol - but has a way of then invading the (in my case Rayon) mounted wicking material. When coil-wick interface is at temperature (greater than a 200 *C temp is not unusual), it (may) be that some components of such semi-soluble coil-gunk (may, gradually) enter into vapor particles.
I’ve emailed most of the flavouring companies to ask which of their consentrates contain Triethyl Citrate. I will continue to update the list in my original post with their answers.
Honestly, I’m a bit sceptical and probably would require more testing and proof before jumping to conclusions.
I’ve used juices that allow me to vape using a gunked up coil, even with the ingredients you mentioned, but I only ever see more gunk building up (to the point where large pieces break off, likely due to thermal stresses).
Gotta wonder… where do those bits and pieces go after “breaking off”…
This is why it is suggested to not reuse pods and pre-built coils.
It’s simple enough to change out your cotton and coil on rebuildables…
Yeah, no kidding Usually I change coils & wicks every 5 to 7 days but sometimes I forget or don’t have time or opportunity. I just drip through the drip tip and don’t watch my coils so every so often when I change, I’m appalled by the state of it. Thick black crust, bits and pieces of gunk in my wick. With some juices you taste immediately when something’s up. Other juices you can just keep vaping on and on without realizing how much too far you’ve taken it.
I must be an odd ball… I change cotton every day, coils eh… between 3-4 days… depending on what all I am vaping… I think the clearest juice I had (btw cookies and cream really do not darken/change coloring much) my coil has lasted me over a month… but I am more concerned with the cottons… they harbor all kinds of things
Pods… once they are empty, I toss… I used to reuse… but once I saw how black they get… its a tummy turner!
I’m waiting for a response from Flavorah but have you noticed any of their consentrates to blend or emulsify? I find FLV Boysenberry to be hard on my Pods but is such a great flavour.
