Cold process soap recipe for Refreshing Watermelon Soap


Base oils

Sodium hydroxide solution


Mixture of essential oils and aromatic essences




Steps to follow

  1. Prepare and sterilize your equipment and workspace.
  2. In a ramekin, weigh and mix the essential oils and aromatic essences with the orris root powder.
  3. In the three other ramekins, weigh the colourants (1. dark green oxide; 2. bordeaux mica; 3. green oxide, yellow oxide and titanium dioxide).
  4. In the last ramekin, weigh the blueberry seeds.
  5. In a small bowl, weigh the superfatting oil.
  6. Take out the silicone loaf mold and keep on hand so that you can pour the different soap batters as soon as they are ready.
  7. Take the necessary precautions for working with sodium hydroxide.
  8. Prepare the sodium hydroxide solution (measure demineralized water and sodium hydroxide separately, add the sodium hydroxide to the water, mix carefully) and let cool.
  9. While the sodium hydroxide solution is cooling, weigh the coconut oil, palm oil, and cocoa butter in a large stainless steel container. Melt this mixture in a double boiler. Once melted, remove from heat, and add the olive oil, sesame oil, and castor oil. Let cool.
  10. Pour a little of the oil and butter mixture made in step 8 into each of the three measuring funnel pitchers. Transfer the colourants from the three ramekins into the measuring funnel pitchers containing oil (one for the dark green, one for the bordeaux, and one for the green/yellow oxidex and titanium dioxide). Dissolve colourants in the oil, and crush any colourant granules with a silicone spatula. This will prevent lumps from forming when you add the soap batter to the colourants (step 13).handmade soap recipe
