Hi you all! I've been experimenting with different proportions of lard, coconut, olive, and castor oils in my CP goat milk soap. So far the only negative review I've received is that it isn't as "slippery" as the soap my dad is used to. Looked it up and saw that adding avocado oil is good to help with that. Or maybe rice bran oil. Or high oleic sunflower... So my question is, what oil(s) should I add to the recipe next? Avocado, RBO, HO sunflower, or a different one? HO canola or PKO? What is the best bang-for-your-buck place to buy the one you suggest? I'm also looking for a cheaper place to buy castor oil since I've been getting the little bottles at Walmart. Thanks!
