Bar Soaps
Basic Bar Soap

    Date : 2011-06-08


    This recipe is the basic recipe that we use to test fragrances, colors or other additives.



      Soap Spoon
      Mold of your choice (We typically use a Rubbermaid Drawer Organizer #2915)
      Plastic wrap or bag Immersion Blender
      Mixing containers


    Line the mold with plastic wrap or bag. This will make the removal of the soap from the mold easy.

    Measure oils on your scale. Warm on the stove or in the microwave. Bring temperature to near 120 F. Exact temperature is not critical. Add sodium hydroxide to the water. Mix well. Allow to cool to near 120 F. Once again, exact temperature is not critical.

    Combine oils and lye solution. Stir until thin trace. Upon trace any desired fragrances or additives. Stir well. Pour soap into molds. Allow to sit until soap is firm.

    Cut into bars. Stack to allow good air circulation. Allow to cure for several days before using. Longer curing will result in a harder bar.


    We use either Coconut Oil or Palm Kernel Oil since they have similar saponification values. We will just use what we have available in the lab at the time.

Decadent Ingredient

Aloe Vera Butter
Aloe Butter is one of those versatile ingredients that I think should be in every cupboard. It makes fabulous soaps, creams, scrubs, butters, and lip balms.

Purple Lovers Unite

Lavender Fields Color
I think Lavender Fields makes wonderful colored soaps. You can swirl with it, make confetti soap or just have a single colored soap. Start planning to make some purple soap for your purple loving friends or customers!
