Description
A class of synthetic, water-soluble, detergents that are most commonly used as surfactants. In anionic detergents, the hydrophilic portion of the molecule carries a negative charge. They contain anion groups (sulfate, sulfonates, or phosphates) combined with an alkali or an ammonium cation and a long-chain hydrocarbon. Examples are soap, linear sodium alkyl benzene sulfonate (LAS), linear alkyl sulfate and linear alkyl ethoxy sulfate. Anionic detergents act as a wetting agents, but will precipitate when combined with cationic surfactants. They generally form alkaline solutions and thus, should not be used on wool.
