Over the weekend I found a large chunk of well dehyrated castille soap frm Provence. On a lark I chopped off a piece, cut into small pieces, added a small amount of olive oil (clearly a mistake) and lacking clay I had a old bottle of original formula Kaopectate made from pectin and kaolin. Popped into microwave-stirred and got an odd goo that when cooled had an odd rubbery quality-prob from the pectin. After cooling I attacked it with my Rooney and got volumes of poor quality lather and a poor shave. So as an isolated product it was terrible but it may be the first antidiarrheal shave soap!
