I hate messing with water extractions. the tobacco soaks up 5 times it's volume like a sponge, and then turns into a mush that can't be worked with. Maybe I'm doing it wrong?
If interested, there is a good writeup in the "Lorillard" papers on water extraction, including a multistep partitioning approach that greatly increases initial concentration. Someone have the link? I lost my bookmarks when I changed OS.
I've used heavy mineral oil with great success. the SG and viscosity difference isn't huge.
Vegetable oils may be better. I left them alone to try to eliminate variables.... which there are a lot of in vegetable oils.
All the extra stuff in vegetable oils may make it a more aggressive solvent, but not necessarily for the stuff we want.
DVap has confirmed the alkaloids miscibility in mineral oil.
Thanks for the info tceight.
I did a water extraction with snus. Was pretty easy to squeeze the snus pouches almost dry (with rubber gloves) then filter out the fines. Then the problem is to much water volume like kina said (which could be reduced).
I tried to vape some of that extract but was not impressed (like virk was). To much water, to much junk.
BTW, what is "SG"?
I guess I'll stick with the heavy mineral oil for now.
