Can calcium hydroxide be used in soap making? - Quora

Stearin should work fine. These will react much easier with a warm to hot solution of Sodium carbonate (Na2CO3, this is not baking soda!). The fatty acid should be in a liquid form, not solid to warrant a thorough reaction. You may want to add the sodium carbonate slowly to avoid a too vigorous reaction.
