Olive Oil Soap Ingredients: 700g Palm Kernel Oil 200g Olive Oil 100g Coconut Oil 140g Caustic Soda Heat Palm kernel, Olive and Coconut Oils slowly to melt together and cool until 45 °C. In a separate container, add caustic soda to 320 tap water. Be careful not to allow mixture to contact skin or eyes. When caustic soda has cooled down to 45 °C pour into Oil mix. (Take note: Both have to be 45 °C when added together) Now would be the time to add in any herbs or aromatic oils you desire. If using essential oil add in 35ml. And whizz with a stick blender in the same direction. Pour into clean moulds (Use plastic/wood – NOT stainless steel moulds). Leave to set for 8 hours and then can be cut if in a long mould. Soap should be given 6 weeks to harden but can be used before. Just means it’s softer.
