Hello everyone! I've made a few batches of HP beer soap, which I have included 5% castor oil in. I saw somewhere that a soapmaker left off the castor oil when using beer, because it makes great lather on its own. I'm getting ready to make more beer soap...and also wine soap, which I assume would have similar qualities? Any thoughts on this? Can I/should I leave off the castor oil? Also, would it produce the same lather when using HP and CP? Thanks!
