How to Make Cold Process Soap

Here’s how to make soap at home using cold process. It seems complicated at first, but it’s actually quite easy once you get started, begin with a basic recipe.

Equipment

  1. Silicone Soap Mold
  2. Soap Cutter and Box
  3. Basic Stick Blender
  4. Lazer Temperature Gun
  5. Digital Scales
  6. Safety Glasses
  7. PH strips for safely testing acidity
  8. Long Rubber Gloves
  9. Large stainless steel pan
  10. Large plastic /glass jug or plastic bucket.
  11. Spatula
  12. An old towel

You will need to measure your ingredients carefully, Do Not try to guess or use cup sizes as when you make soap it needs the correct mixture to complete the saponification process.

Prepare a mold. If you don't have a specific soap mold, then any good size container will do.

This is a base recipe only. The step-by-step instructions of individual projects may vary. Before you begin, assemble your ingredients. If needed, prepare safety gear such as goggles, gloves, and long sleeves. Cover your work surface with newspaper.

  1. First, weigh the lye in a heatproof container. Weigh water in a separate container. (Note: A lye calculator is handy here: simply enter the oil weight or percentage, and the tool will provide the lye and liquid amount needed for the recipe.)

  2. Next, carefully pour the lye into the water, stirring gently with a heatproof utensil until the lye has fully dissolved. Set aside, and let cool for up to an hour.

  3. While the lye solution is cooling, weigh oils or solid butters. Melt with a double-boiler until up to 100 degrees.

  4.  Measure the temperature of the lye and oils. Use different thermometers for the lye and oils, and continue to monitor their temperatures until the lye reaches 95-98 degrees Fahrenheit (35-36 degrees Celsius) and the oils are at the same or lower temperature.

  5. Pour the lye solution into the container of oils. Stir until trace is reached. (Trace refers to the point when the oils and lye solution have emulsified. At this stage, there should be no streaks of oil, and the soap will have the consistency of batter.) Then add any extra ingredients—such as natural exfoliants or colorants—stirring to combine.

  6. Carefully pour the melted soap into the mold. (The soap is still caustic at this stage, so keep your safety gear on when handling.) Cover the mold with a sheet of paper. To retain heat, wrap a towel around it. Set aside for up to two days or until completely cool and solid.

  7. When ready, remove homemade soap from the mold and slice it into bars. Let the bar soaps cure in the open air for at least four weeks before using.



Adjusting The Volume Of Your Scent
You can adjust the scent volume here up to 3% of all the oils and water added together. Anything over 3% would be very strong depending on the oils you are using, so I recommend starting at 2%.
