Known for their ability to cleanse and draw out oils and impurities, Using Cosmetic Clays in cold processed soaps is a simple way to make great soap recipes even better. For a gentle clay that is kind to all skin types, go with the Kaolin or Rose Clay varieties. For something stronger and extra absorbent, look to French Green, Bentonite, or Rhassoul.
Kelly’s test recipe used 33% coconut oil, 33% palm oil, and 34% olive oil. She added 1 tablespoon of clay per pound of soap. The resulting colors will look a bit different depending on the oils you use in your own recipes. Since the colors of natural oils and natural soaps can vary, remember to leave a little bit of wiggle room in your expectations.
To add Cosmetic Clays to your batch, blend about 1 tablespoon of clay per pound of soap into the warmed oils (before mixing with lye water). You can add an additional tablespoon for a deeper, more intense color, or a little less to make the color more subtle. Just remember that the added Clay may also affect the soap’s texture. Using Cosmetic Clays in cold process soaps can give them a little extra grit and sometimes even a richer lather.
