I have been making my own homemade foaming hand soap for a while, using regular hand soap and using this recipe. It’s relatively easy. However, I ran out of soap. I was contemplating buying some, but then I remembered that I have Peppermint Castile Soap. So I googled it!
I found the directions here for foaming hand soap using just castile soap and water! My soap smells awesome, looks better than the old soap, and is SOOOO easy to make. I didn’t even measure. The other recipe requires warming up the water first. This takes NO extra dishes.
