While reading a different thread this question came to my mind. Bees Wax, Stearic Acid and Cocoa Butter generally lend to making hard bars of soap. Do they also to an equal degree cause faster acceleration of trace? Other than personal preference, and price, are they essentially the same when using them for their hard soap quality? It was suggested to me in the past using Stearic Acid should be used in Hot Processed soap making, but not Cold Process. Does this hold true for Bees Wax and Cocoa Butter as well?
