Abstract: Powdered detergent compositions containing a surfactant, fillers, builders and the like, can be prepared by removing water from the detergent composition to form the powder. Frequently, such powdered detergent compositions are hygroscopic and lose the free-flowing characteristics upon storage. According to the present invention, a detergent composition which comprises at least 5 percent by weight of a mixture of alkyl benzene sulfonates wherein greater than 55 mole percent of the alkyl benzene sulfonates have alkyl chains of greater than 11 carbon atoms, the alkyl chains having 12 or more carbon atoms have a 2-phenyl content greater than 60 percent of the total 2-phenyl content, along with other detergent ingredients are provided which provides a free-flowing dry composition that is less hygroscopic than prior art products.
