All Dr Bronner soaps are certified under the USDA National Organic Program by Oregon Tilth: they source all the core soap and essential oils organically, not just minor additive ingredients, in order to support and encourage sustainable agriculture, farm worker health and ecological processing methods.
Dr Bronner's Bar soaps are "Pure-Castile", meaning a real ecological and simple soap, not a complex blend of detergents. Dr Bronners Bar soaps are produced with certified organic oils, and are available in the following varieties: peppermint, lavender, rose and tea tree.
