Recipe: Handmade "Silk" Soap

Recipe: Handmade "Silk" Soap



  • 300g coconut oil
  • 200g olive oil
  • 100g shea butter
  • 100g cocoa butter
  • 150g sodium hydroxide (lye)
  • 350ml water
  • 30ml silk protein
  • 20ml fragrance oil (optional)
  • Colorants (optional)


  1. Prepare your workspace with protective gear, including gloves and goggles.

  2. In a well-ventilated area, carefully add sodium hydroxide to water (never the other way around) and stir until dissolved. Allow to cool.

  3. Melt coconut oil, olive oil, shea butter, and cocoa butter together in a heat-safe container.

  4. Once oils and lye solution are around 38-43°C, carefully mix them together. Use a stick blender to emulsify until trace is reached. This is when the mixture thickens to a pudding-like consistency.

  5. If adding fragrance oil or colorants, do so now and mix thoroughly.

  6. Pour the soap batter into molds and cover with a towel or cardboard box to insulate.

  7. For cold process: Allow soap to cure in the mold for 24-48 hours before unmolding and cutting into bars. Let the bars cure for 4-6 weeks before use.

  8. For hot process: Cook the soap batter in a slow cooker on low for 1-2 hours until it passes the zap test (touch a bit of soap to your tongue; if it zaps like a battery, it needs more cooking). Mold and allow to cool before cutting.

  9. Once cured, enjoy your luxurious handmade "Silk" soap!
