A Basic Cold Process Soap Recipe:

Note: All measurements are by weight, NOT fluid ounces! Always put the empty container on the scale first, then "tare" or clear the weight to zero before adding ingredients.

Cover your work area with newspaper to protect it and keep paper towels and water nearby to clean up any spills.

Lye Water Solution:

Distilled Water - 10 Ounces
Sodium Hydroxide - 4.8 Ounces


  • First - Put on your protective eyewear, gloves and face mask!
  • Using the scale, weigh the distilled water into the large Pyrex measuring cup.
  • Separately weigh the sodium hydroxide (lye) into a disposable paper cup.
  • *** IMPORTANT!! ***
    Carefully add the sodium hydroxide (lye) to the water - and NOT vice versa!
  • Use a stainless steel spoon to mix the two ingredients well. The mixture will get hot quickly and you will see fumes immerse. When lye is fully dissolved, set the mixture aside in a safe place to allow to cool.

Oil Mixture:

Olive Oil - 1 Pound 2 Ounces (18 oz.)
Coconut Oil - 8 Ounces
Palm Oil - 6 Ounces
Castor Oil - 1 Ounce


  • Using the scale, weigh the hard, unmelted coconut and palm oils, then melt these two oils. This can be done in a microwave if using a glass bowl, or a double boiler if using stainless steel.
  • Weigh the olive and castor oils into the melted coconut and palm oils. Remember to zero out the scale between additions or you will have to do the math!
  • Give the oils a few stirs to mix them and set them aside to cool.

Next Steps:

  1. When the lye water and the oils mixture reach temperatures that are within 5 to 10 degrees (F) of one another, add them together by carefully pouring the lye water into the oil mixture.
  2. Give the mixture a few gentle stirs with a spoon, then immerse the stick blender into the mixture and begin to blend.
  3. Mix well with the blender until the mixture reaches "trace". You will recognize "trace" if you lift the blender out of the mixture and the dribbling liquid leaves a mark on the surface. It will be thick like pudding or pancake batter. At this point, the lye water and oils mixture can no longer separate back to their original form, and the soap making process is well under way!
  4. Once "trace" is reached, you may add fragrance oils, essential oils, colorants, and/or other additives. If any of these additives have been used, give the mix a few short blasts with the stick blender to fully incorporate it into the mixture. If trace has been lost due to the inclusion of additives, continue to mix until trace is reached again.
  5. Pour the mixture into your soap mold.
  6. After 48 hours, the soap may be unmolded and cut, if necessary. Place the bars on a rack (out of reach of young children!) to cure for 4 to 6 weeks to ensure complete saponification, correct pH, and hardness. After the curing phase, the soap is ready to use.

This recipe yields 2 lbs of soap.
