my friend wikdsushi wants to know this for the novel she's writing:
I just realised that I have no idea whether tallow soap falls under the same kashrut restrictions as food. Is it permissible to use soap made from hard fat and/or fatty, non-kosher organs (kidneys, etc.) and the fat around the sciatic nerve, or does soap fat have to come from specific areas of the animal?
One can derive benefit from non-kosher parts of animals (the only non-kosher thing we're not allowed to derive benefit from is meat and milk together). Therefore, I can see no reason that tallow soap would be prohibited. You couldn't *eat* it, but you wouldn't particularly want to do that, anyway.
