How to Make Soap with a Slow Cooker

Soap.PNG

Equipment

  • A slow cooker
  • A scale (this is important for making a soap that is not too harsh or too oily)
  • Glass jars and bowls
  • A stick blender
  • Plastic cups (optional)
  • A metal spoon
  • A wooden spoon
  • A spatula
  • Soap molds (or an old cardboard box lined with parchment paper).
  • A large bottle of white vinegar for neutralizing the lye mixture if it spills on anything.

For Your Safety

  • Gloves
  • Eye Goggles

Soap Recipe Ingredients

  • 0.760 pounds water ( 12.16 ounces or 344.73 grams)
  • 1 pound (16 ounces or 453.6 grams) coconut oil
  • 1 pound (16 ounces or 453.6 grams) olive oil
  • 0.303 pounds Lye (4.844 ounces or 137.339 grams)
  • Up to 1 ounce of essential oils of choice (optional)

Soap Recipe Instructions

  1. Make sure that your work area is clean, ventilated and that there are no children nearby. This is not a good recipe to let children help with since Lye is caustic until mixed with water and oils.
  2. Measure the oils in liquid form (by weight) and pour into the slow cooker.
  3. Turn on high just until oils heat up and then reduce to low heat.
  4. While oils are heating, carefully measure the lye and water separately. TIP: Use disposable plastic cups. They don’t weigh anything on the scale so they make measuring easy.
  5. Keep 3 separate disposable plastic cups labeled:
    1. Water
    2. Lye
    3. Oil
  6. Carefully take the cups with the water and the lye outside or to a well ventilated area.
  7. Pour the water into a quart size or larger glass jar.
  8. With gloves and eye protection, slowly add the lye to the water.  (Warning: DO NOT ADD THE WATER TO THE LYE!)
  9. Stir carefully with a metal spoon, making sure not to let the liquid come in contact with your body directly.
  10. As you stir, this will create a cloudy white mixture that gets really hot.
  11. Let this mixture set for about 10 minutes to cool. It should become clear and not cloudy when it has cooled.
  12. When the oils in the slow cooker have heated (to about 48-54 degrees Celsius or 120-130 degrees Fahrenheit), slowly pour in the water and lye mixture and stir.
  13. Quickly rinse the container used for the water and lye mixture out in the sink. Rinse with white vinegar to make sure all Lye has been neutralized.
  14. Use the metal or wooden spoon to stir the lye/water mixture into the oil mixture in the slow Cooker.
  15. Once it is evenly mixed, use the stick blender to blend for about 4-5 minutes or until it is opaque and starting to thicken.
  16. Cover and keep on low heat to thicken.
  17. Set a timer for 15 minutes and check it every 15 minutes until it is ready. It will start to boil and bubble on the sides first.
  18. After about 35-55 minutes (depending on your slow cooker) it will thicken enough that the entire surface is bubbly and the sides have collapsed in.
  19. At this point, turn the heat off.
  20. If you are going to use essential oils (e.g. lavender and orange) for scent, add them now.
  21. Quickly and carefully spoon into molds (e.g. empty boxes lined with parchment paper).
  22. Cover the molds with parchment paper and set in a cool, dry place.
  23. After 24 hours, pop the soap out of the molds. For best results, let it set for a few more days so that it lasts longer.
