    • Laundry granular detergent compositions useful for hand wash and machine-assisted hand wash laundry operations. The composition contains 5% to 40% of a surfactant, the surfactant containing: 1) 60% to 95% primary anionic surfactant selected from alkylbenzene sulfonate, alkyl sulfate, and mixtures thereof; and 2) 2.5% to 18% alkyl ethoxy ether sulfate (AES) surfactant having an average of from about 1 to about 9 moles ethoxy per mole surfactant, the ratio of alkylbenzene sulfate and alkyl sulfate surfactant to alkyl ethoxy ether sulfate surfactant being within the range of from about 30:1 to about 4:1. The composition also preferably contains 2.0% to 5.5% hydroxyalkyl quaternary ammonium cationic surfactant, the ratio of alkylbenzene sulfonate and alkyl sulfate surfactant to such cationic surfactant being from 40:1 to 16:1. The detergent laundry composition is mild to the hands, and provides superior cleaning performance under high hardness and underbuilt wash conditions, and improved cleaning performance on greasy and body soils. The incorporation of the AES surfactant into the surfactant system also provides improved cellulase enzyme activity on cellulose substrates washed in the detergent composition.
