  1. Hi ! My goal is to create lotion with NaoH /stearic acid as emulsifier. My oil phase is: 15% mineral oil 20% isopropyl myristate I need to calculate how much NaOH is needed to saponify 5% stearic acid. Chemical reaction will be as follow: C₁₇H₃₅COOH + NaOH ⇒ C₁₇H₃₅COONa + H₂O My question is should I included saponification value for stearic acid or treat this calculation as normal proportion: 284.4772 g/mol - 40 g/mol 5% - x Second option as I have mentioned is taking into account saponification value for stearic acid which is between 206 and 212, so let's say for calculation purpose we will take 209. So then I would have to recount amount KOH for the NaOH. It seems to be easy, but I think I am lost here ! Any help ?
