Not a chemist but not sure I agree that burning on the coil is a certainty. It would seem possible that "emulsee" might just "ride out" the vaporization. That is, vapor produced from ingredigents of the e-liquid with lowest boiling point and aerosolization of condescending vapor which "emulsee" re-emulses within. Dependent on the particle size of the "emulsee", aerosolized particles that carry the "emulsee" likely larger that other moving particles and more likely to impact in the mouth areas - probably a positive for taste purposes. To me, seems possible. I would think it might be worth an experiment or two. Just might create the vape that, so to speak, hits the taste buds best.

I would not be keen to inhaling compounds that are designed to wed water-soluble with water-insoluble compounds, which is what emulsifiers are for. Lecithin is a commonly used one. Big fatty molecules with polar head groups. regardless of what they will do to an atty, which Hoosier tested, they would likely linger on lung tissue for longer than PG, VG or flavor compounds. In fact, the molecules that make up lecithin complex are very similar to those that make up cell membranes, so I could see them not just lingering in the lung, but setting up home there.

the lack of flavor does not surprise me, Hoosier, as they will surround flavor compounds and keep them from being available to receptors. Similar to soap making miscelles around grease particles.

Although I am flattered that the Old Chemist agreed with me, what I was saying was not totally consistent with what Kurt was saying. You might look here for some insight. Emulsion - Wikipedia, the free encyclopedia

An extract:
An emulsion ( /ɨˈmʌlʃən/)[1]is a mixture of two or more immiscible (un-blendable) liquids. Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion tends to imply that both the dispersed and the continuous phase are liquid. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, the photo-sensitive side of photographic film, milk, and cutting fluid for metal working.

It is still common belief that emulsions do not display any structure; i.e., the droplets (or in case of dispersions, particles) dispersed in the liquid matrix (the “dispersion medium”) are assumed to be statistically distributed. Therefore, for emulsions (like for dispersions) usually percolation theory is assumed to appropriately describe their properties. However, percolation theory can be applied only if the system it should describe is in or close to thermodynamic equilibrium. There are very few studies about the structure of emulsions (dispersions), although they are plentiful in type and in use all over the world in innumerable applications.

In the following, only such emulsions will be discussed with a dispersed phase diameter of less than 1 µm. To understand the formation and properties of such emulsions (including dispersions), it must be considered that the dispersed phase exhibits a "surface", which is covered ("wet") by a different "surface", which, hence, are forming an interface. Both surfaces have to be created, which requires a huge amount of energy, and the interfacial tension (difference of surface tension) is not compensating the energy input, if at all.

A review article in [1] introduces into various attempts to describe dispersions and emulsions. Dispersion is a process by which, in the case of solids becoming dispersed in a liquid, agglomerated particles are separated from each other and a new interface, between an inner surface of the liquid dispersion medium and the surface of the particles to be dispersed, is generated. Dispersion is a much more complicated, and less well understood, process than most people believe.

What comes across to me - both of the two exist as liquids. Each liquid may or may not have same boiling points. The particle size of each may be very small - but it is not a requirement. To me, there are two many possibilities to say any and every emulsion fails an atty or sticks to the lungs. I think it's a situation that "it depends". That is, it depends on what is "dispersed" and what it is "dispersed" in. Energy from the coil will change things. But just how changed - "it depends". And whether thermodynamic equilibrium exists by the time a mist generated from the coil enters the mouth - I think an unknown - since "emulsion" by itself leaves much undescribed.

Well it was not totally consistent, but it also was not totally inconsistent, right? There are different emulsions. Probably some of them are less harmful. A friend of mine (doctor) suggest inhalations with some amount of vitamin A (dispersed in oil) mixed with other ingredients, so technically speaking it's quite similar to vaping an emulsion.
You're absolutely right JW50 that thermodynamic equilibrium of this system is very, very complex and we have too many variables here to be sure what is right and what is wrong.

I see a bunch of text, but nobody but me actually trying them.

Go to a bakery supply. Buy all the emulsions you like. Mix the stuff and vape it.

Then tell us what you discovered.

all the theory typing in the world doesn't make grandma's pie any better.

Take the challenge. Make grandma's pie better.

No offense intended Hoosier. Not much a cook myself so not likely I'll be in the kitchen. But obviously you have found that some emulsions just gum things.

I'm not entirely sure I can be offended. Well, at least I haven't been for about 30 years.

Try harder and we'll see...

(I wasn't the one who tried to use salt, but I have tried some silly stuff in the course of my mixing.)

Still want to create my grandma's paperbag Apple pie, but I'd settle for fairly good pie...

OK, Hoosier, but... what's the point? Trying to find something extra just by wild guess (while risking your health)?

The point?

Health?

I didn't know either was needed in this thread. This emulsion thing keeps popping up and i keep telling folks what they are like. I'm encouraging folks to not believe me and find out for themselves. It would be nice to have a few more to answer this question the next time it comes up with actual experience too so folks don't have to believe a lone nut like me.

I doubt that after decades of smoking that some silly edible liquid is going to be my downfall. it did take out a good atty. (The others were of the so-so type i keep around just for testing mixes.)
