Janet's Pure Olive Oil Soap
A classic olive oil soap using the cold Castile method.
Materials
- 400 g Olive Oil
- 77 g Distilled Water
- 51.5 g Caustic Soda
- 1 tsp Salt
- Mica pigment for colour
- Essential Oil
Instructions
- Do the first process in the open, as it lets off fumes and you need to be careful (ideally wearing glasses and gloves) as it gets very hot, so you need a good plastic container and a strong wooden/plastic spoon (not to be used for anything else)!Add the caustic soda to the water and stir, and add the salt, this helps it to set. It will get very hot while the reaction works so leave outside (somewhere safe) while it cools down.
- When cool add the caustic soda mixture to the olive oil and whisk with a stick blender. It will thicken, but not too much. Add essential oils, and colour if you want. Mix thoroughly. I also add Vitamin E drops. Use a jug to help you pour into moulds. Leave for quite a few days before turning out, and leave for up to a month for the soap to harden, depending on the temperature and humidity.
