We love our Dr. Bronner’s liquid castile soap, but for those who want to go the extra step and prefer to make this soap for themselves, we provide three instructional guides below, they are very similar so you use the one that resonates best with you. Liquid castile soap is key base ingredient in so many homemade products from shower washes, hand soaps,

This is a good afternoon project that will take some time, but is fairly straight forward and once you do it,
you will have a good supply to fill your other needs.  It does involve handling volatile materials so protective eye wear and rubber gloves are a required, and special attention to the sequencing of activities.

What you’ll need is:

Equipment:

  • Crock pot (6 quart or larger) or slow cooker (for soap making only, not for food)
  • Immersion blender
  • digital scale that can measure both ounces and grams
  • Gloves
  • Goggles
  • Containers to store your soap (old apple cider glass jugs work great)

Ingredients:

  • Potassium hydroxide (not to be confused with sodium hydroxide which is used for solid soap lye)
  • Oils (traditionally use 100% olive oil, but can mix 60% olive oil / 40% coconut oil
  • Distilled water
