My freezer doesnt go below 0F so thats just where i stop at. If you used dry ice you would probably be able to get even more to drop from the solution.
You should definitely try to chill your solution colder and re filter, usually some amount of waxes and oils will dissolve back into the solution as the semi saturated solvent passes over the lipids trapped on the surface of your filter.
If you collect the waxes from a warm methanol winterization and evap the solvent, you can compare it with what comes out after you do the same thing with a cold methanol winterization. What comes from the warm filtration is usually pretty greasy but has some stability to it. The cold filtered portion is always a greasy oily mess with no structure to it. This has led me to believe that the waxes that add some kind of stability are the first to preciptate from a methanol solution whereas the oils which would come from the seeds or from pesticides are the last to precipitate in a winterzation procedure.
@Roguelab this answers a question u asked in another thread.
