But be careful when you build the fatty acid profile of your recipe and let it help you determine the final % of each oil in the 3 (or 4) categories mentioned above. For example, a soap with 40% regular sunflower oil will not behave the same as one with 40% olive oil. Check the link provided, research some more, and with enough practice you'll soon learn how to properly substitute oils to get similar qualities. And you'll get to know what everything (or at least the most important parts) in the calculators mean. Good luck!
