Homemade Hot Process Soap Recipe in a Crock Pot
Author: 
Recipe type: DIY - Soap
 
Ingredients
  • 10 oz olive oil
  • 20 oz coconut oil
  • 9 oz distilled water
  • 4.78 oz 100% pure lye (like this)
  • Essential oils for scent (optional)
  • Other Equipment:
  • Digital scale (like this)
  • Safety gear (safety glasses, long sleeves, gloves)
  • Stick blender (like this)
  • Crock pot
  • Non-metal dishes and utensils
Instructions
  1. Measure out the olive and coconut oil.
  2. Place the coconut oil in the slow cooker, and turn it on so it begins to melt.
  3. Measure out the other ingredients, weighing each and every one on the digital scale first.
  4. Once the coconut oil has completely melted, add the olive oil to the crockpot and allow it to mingle and warm up.
  5. Add the lye to the water, stirring slowly. Do this in a place with ample ventilation, while wearing your safety equipment.
  6. Add the dissolved lye/water mixture to the melted oils in the crockpot. Stir gently.
  7. With the stick blender, continue to mix/stir for several minutes until you reach "trace."
  8. Place the lid on the crockpot, set the timer for 50 minutes, and allow the mixture to cook on LOW.
  9. If the soap tries to bubble out of the crockpot, give it a stir.
  10. Line the soap molds with parchment paper (if required)
  11. Once the 50 minutes has elapsed, perform the "zap test": I like to do this by grabbing a small amount of the soap mixture, allowing to cool for a second, and then touching it to my tongue. If it "zaps" me, I know there is still lye remaining in the mixture and it needs to cook longer. If it just tastes like soap, we're ready for the next step.
  12. Allow the mixture to cool slightly before adding any additives.
  13. Press/pour the soap mixture into the mold, making sure to press it into all the corners and smooth out the top as much as possible.
  14. Set it aside for 12-24 hours, or until it sets completely. (Usually, overnight is plenty of time).
  15. Remove the soap from the mold, cut it into bars.
  16. Allow it to dry for another day or so to allow it to harden up a bit.
