its because of that "difference in miscibility" i bet. ill have to look to be sure, but i think with glycerine being an alcohol, and ffa being a lipid that the glycerine will dissolve in the water, but ffa's do not. i also wonder if the ffa content can be used in place of castor oil to distill ethanol...another thing to look into.
