I use pomace because it is supposed to be better for soap. I am starting to rethink because of the solvents used for its extraction but haven't decided to change yet...
I'd think the heat involved in the reaction (assuming HP) would drive off any remaining solvent (which I think is hexane). PLus the alkali hydrolysis would also presumably destroy any remaining solvent ...?

Nope. And the trace hexane isn't going to boil off - the concentration too low for the partial pressure. And while hexane isn't that horrible for you compared to many other solvents, what happens when it's ingested (or absorbed through the skin) over a lifetime. I live near Chemical Valley, and there were days where the wind wasn't blowing the usual way and we'd be able to smell the plants as we went to schoool. Even with just periodic exposure to the mixed gasses, we have huge gains in the cancer rate (despite the fact the plants are miles away on the far side of a wide river in a different country. Some of the chemicals are just really bad.There is an interesting wikipedia page regarding hexane. Doesn't look like it would be affected by the lye at all ... interesting.
