I have one from my notebook that I like a lot.
When I ran out of coconut I used the following recipe for several 1# tests. In addition to the ingredients below I added various teas, herbs, coffee etc just to play a bit.
This will make about a 1 pound batch so if you want 30 oz. you could double it. Of course run it through a soap calculator. But these produced really nice general purpose soap with good lather and bubbles. A little high in Palm but not at all irritating. And after a couple of weeks they were hard as rocks.
