Mix 1 cup baking soda with 1/4 to 1/2 cup liquid castile (vegetable based) soap. Add as much liquid castile soap as necessary to get the creaminess you want. This will keep for up to a year if you add 2 teaspoons of vegetable glycerin.
For a pleasing fragrance add a few drops of your favorite essential oil.
