Adding cooking oil to encourage freeze precipitation?

[SpasticSpaz]

So SWIM is using the STB + freeze precip method to acquire spice, as he's been living in an apartment where odd smells from evapping a solvent may not rub his neighbors the right way. His freezer isn't terribly good, so he accepts lower yields than he might otherwise.

But he had a thought: Freeze precipitation is dependant on DMT's relatively poor solubility in naptha. If one were to increase the xlogp of naptha, DMT would become even less soluble in it. Soybean oil has an xlogp of ~6 based on those of its components, and has a freezing point lower than what SWIM's freezer can reach (SWIM tested this to verify).

Would it be a worthwhile experiment to add cooking oil to his DMT-bearing naptha to see if it encourages freeze precipitation? Or is this just a completely silly idea? SWIM wouldn't want to waste DMT unecessarily.

I talked this over with SWIM and he says even a crappy freezer will work, just might take a little longer. SWIM states that his freezer is not insanely cold nor does it freeze ice cream solid and he says his works just fine. SWIM also uses much more solvent than suggested here to help avoid black goop in collection jar, just more pulls.
