Yeah I read about Tetrasodium EDTA, but for me I wouldn't have a problem with it, but other people would that use my soap unfortunately. I thought raising the sf would make is worse or am I wrong? I usually sf at 5% except for my facial bar been doing it at 8%, but hubby has complaining it leaves him oily so I wanted to change it. I have several recipes I use, but it's usually Veg shortening, coconut, olive, castor & cocoa butter or shea/mango. I do add salt sometimes before I add lye, but maybe I should be adding more to it? What about doing a all coconut bar? I was so desperate last night we were browsing in the soap isle looking for a detergent bar to use, but came up empty. Any help would be great
