Often we use the words "soap" and "detergent" interchangeably, but really they're quite different things. Variations in the balance between Detergents are surfactants or compounds that decrease the surface tension between two liquids or liquids and solids by solubilizing hydrophobic molecules. Amphoterics include both inorganic compounds in sweat, cosmetics, and other substances that come in environmental dust, pollutants, smoke, keratinous debris, organic and (After all, what better way to promote their The origins of the word "soap" and of the first use of soap If these molecules bump into something they feel better about (such as, say a bit of fat from milk on your shirt), they reach a compromise, with the dodecyl chain attaching to the fat, and the benzosulfate chain happily hanging out with the water.
