Alkylbenzene Sulfonate (ABS)

A major class of aklylaryl sulfonate surfactants used in detergents; usually a sodium salt. ABS is anionic and high sudsing. Prior to the mid-1960s, the form of ABS most widely used in detergent formulations resisted biodegradation. In 1965, detergent manufacturers voluntarily replaced ABS nationally in household laundry products by a more rapidly biodegradable variety of ABS called linear alkylate sulfonate, or LAS.
