My soaping journey began with a formulation of Savon de Castile, but I quickly learned that Castille soap was just the beginning. Soaps have many qualities having to do with how well they clean, how well they foam, how well they condition, and how well they keep, and, depending on the oils you use, these dimensions can vary considerably. So, I set out to make a soap that cleaned and conditioned better, had better foam, and kept better than my Savon de Castile.
