Hey guys & gals! I am in love with making salt bars! Needing to make more but am wondering about subing an ingredient. Looking for suggestions. Current is Coconut oil, Avocado Oil, Castor oil. Wanting to replace the avocado with something maybe cheaper and easier to find but with same value. (have to go to a health food store on the other side of town, sometimes they have it sometimes not) Looked up on SoapCalc and am finding Canola oil is about the same? Is this right? And what is High oleic? Thanks so much for your help.
