Natural Aloe Castile Liquid Soap. These are saponified (soap based) foaming concentrates we make from certified organic coconut, olive and jojoba oils, essential oils, organic aloe vera and rosemary extract. After many trials Vermont Soapworks developed their own proprietary formula called Aloe Castile. We believe it to be the mildest castile soap formula available anywhere! This has become the base from which they have developed their entire line of castile liquid soaps, bath & shower gels and nontoxic cleaners.
