<unk> s A<unk>  is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. There are a large variety of<unk> s; often they are the sodium salts of long chain alkyl hydrogen sulphate or a long chain of benzene sulphonic acid. The most commonly found<unk> s are alkylbenzene sulfonates: a family of soap-like compounds that are more soluble in hard water, because the polar sulfonate (of<unk> s) is less likely than the polar carboxylate (of soap) to bind to calcium and other ions found in hard water.
