Dr Bronner is the largest producer of organic Castille soap in the world — a family-run and owned manufacturer of Castille soap dating back 150 years. All the raw materials used in their products are certified Fair Trade sourced. They do not add any chelating agents, dyes, whiteners, or synthetic fragrances — only the purest certified organic essential oils. They use both coconut and olive oils in the right ratios which produce a soap with a high lather that’s still soft on the skin. The soaps have hemp and jojoba oils, which mirror the natural oils in the skin’s sebum, leaving skin feeling smooth after the soaps are washed away. Their liquid castile soaps are three times more concentrated than most liquid soaps on the market, which means more soap per bottle and less waste in packaging materials.
