Is it possible to prevent saponification by modifying free fatty acids?
doesn't really make any sense. Free fatty acid salts are soaps. Esters of free fatty acids are fats not soaps. Changing the metal counter ions only makes a marginal difference to their soapiness. Different fatty acids make different soaps. Some non fatty acid compounds make good surfactants. The fats that fatty acids are derived from are …
