Alkyl aryl sulfonates were introduced in 1950’s. Today, alkyl aryl sulfonates are the largest class of synthetic detergents. Alkyl aryl sulfonate is used as surfactant material for the detergents. These alk yl aryl sulfonates hold the first place in world markets on account of their excellent properties and relatively low cost of production. Because of their low price this group is extensively used in both the home and industry. Their stability and soil suspending power is not as good as sulfated fatty alcohols. But by adding sodium carboxymethyl cellulose the suspending power can be increased. Alkyl aryl sulfonates come under the type anionic surfactants. These sulfonates ionize in water to give a negatively charged organic ion.
