This easy foaming hand soap contains only water, liquid castile soap, moisturizing oil, and optional essential oils for a simple and frugal homemade soap.
Fill the soap dispenser with water to within about 1 inch of the top. Be sure to leave room for the soap pump foamer.
Add at least 2 tablespoons of liquid castile soap to the water mixture. NOTE: do not add the soap first or it will create bubbles when the water is added.
Add the oil and any essential oils if you’re using them.
Close and lightly swish to mix.
Use as you would regular foaming hand soap.
Notes
You’ll need a foaming soap dispenser for this soap. Either buy one online or reuse the bottle from a store-bought foaming soap.
If you don’t have distilled water, you can also use filtered water that’s been boiled then cooled.
