Although Castile soap requires lye (potassium hydroxide) as an ingredient in its creation, a process called saponification converts the lye and vegetable oils into a new compound, resulting in a lye-free end product. To ensure your soap is organic, choose certified organic oils.
Things You Will Need
-
Turn on the crockpot and set it to the highest heat setting. Add the 47 ounces of olive oil to the crockpot.
-
Put on gloves and goggles. Add 32.9 ounces of the distilled water to the heat-safe container. Mix in 9.39 ounces of KOH flakes to the distilled water.
-
Slowly pour the KOH flakes and water mixture into the oil in the crockpot, using a heat-safe spoon to stir.
-
Stir the oil mixture off and on for about 90 minutes, until the mixture is so thick and rubbery that it's almost impossible to stir.
-
Lower the crockpot setting to medium, put a lid on it and let the mixture cook for 90 to 150 minutes, stirring every 20 to 30 minutes until all the soap is translucent.
-
Boil 1 cup of distilled water. Add a tablespoon of soap to the boiled water. If the water is clear after the soap dissolves, then the soap is done. Otherwise, continue cooking until a sample of soap in boiled water becomes clear.
-
Transfer the soap into a large stainless steel pot. Boil 80 ounces of distilled water in a separate large pot. Pour the boiled water into the soap and let it sit overnight to dissolve.
-
Transfer the dissolved soap and water mixture into jugs and let them sit for four weeks.
