I have always used castor oil in my soaps, but I am looking to cut back on some oils. I love my bars now, and I always have such a nice lather, but I am not sure how much it will change if I don't use castor. Right now I use castor at 8%. I was wondering how those of you who don't use castor keep the bubble factor up. Do you add sugar? Right now the only oils I have to order and have shipped are palm, castor and cocoa butter. I have thought about dropping the palm all together but it is a decent portion of my soap and that would take a lot more reformulating than just dropping the castor. I don't know what to do.
