Natural homemade castile soap

Recipe

Olive oil 855 g /30,16 oz

Castor oil 45 g / 1,58 oz

Lye (Sodium hydroxide) 115 g / 4,05 oz

Distilled water 207 g / 7,30 oz

Superfat 5%

Steps

Step 1. Weight the oils in the pot

Step 2. Weight the lye in separate dish

Step 3. Weight the distilled water in the third dish

Step 4. Slowly pour the lye into the water. Not the other way around, as this can evoke a strong reaction! Make sure you are doing this step close to an open window and remove your head away from the pot. Stir a few times with a plastic or stainless-steel spoon so the lye can dissolve in the water

Step 5. Let the lye solution cool down between 30-50C / 86-122F

Step 6. Heat the oils up to the same degree as the lye solution. Deviation up to 8 degrees is fine

Step 7. Pour the hot lye solution into the oils

Step 8. Mix without moving the blender, then stir manually when it’s turned off. Do this until you get the trace, around 5 minutes.

Step 9. Put the soap in silicone molds

Step 10.

First option; cover the soap with cardboard and a towel. Leave for at least 24 hours but better for 48 hours.

Second option; put the uncovered mold in the previously heated oven (now turned off) on 50C / 122F and leave for 24 hours.

Step 11. Remove the soap from silicone mold and cut with the knife to 2cm / 1-inch-wide slices

Step 12. Let them dry on the rack, covered with cloth, in a cold and dark place, for at least one month but for best results dry for three months
