Dr. Bronner's Magic Soaps: Pure Castile Bar Soap Organic Citrus (2 pack)(140 g, Pack of 2)

Dr. Bronner's Magic Pure-Castile Bar Soap Organic Citrus Orange is made by saponifying a fat or oil with an alkali. A fat or oil is a triglyceride, which means that three fatty acids of various carbon lengths are attached to a glycerine backbone. The alkali is either sodium (for bars) or potassium (for liquids) hydroxide, made by running electricity through salt water. The saponification process is a simple one-step reaction with no waste generated: the glycerine is split off from the fatty acids, and the fatty acids combine with the sodium or potassium to form soap, while the hydroxide forms water. The result is soap, glycerin and water (no alkali remains in our soaps).
