I'm looking to make a soap with 60% safflower oil (high linoleic kind) and 40% shea butter. After putting into soapcalc, I see that I need help with hardness and lather. I plan on adding kaolin clay and a little oat flour. I did some research and will add sodium lactate at 2% for hardness. Should I add sugar too for the lather? Do you think this recipe will turn out ok?
