How Do You Make Foaming Hand Soap Refill?
To make foaming hand soap refill, you will need a soap dispenser bottle, liquid castile soap, water, and essential oils (optional). Fill the soap dispenser bottle halfway with liquid castile soap and then add water until the bottle is almost full, leaving a little space at the top. Add a few drops of essential oils if desired. Screw on the top and gently shake to combine. Pump the dispenser to create foaming hand soap.
