Abstract
A granular detergent composition containing a secondary (2,3) alkyl sulfate surfactant and a bleach/bleach activator system which has improved cleaning performance is provided. The detergent composition comprises: (a) from about 1% to about 40% of a secondary (2,3) alkyl sulfate surfactant; (b) from about 0.005% to about 5% of an enzyme; (c) from about 0.5% to about 20% of a peroxygen bleaching agent; and (d) from about 0.5% to about 20% of a bleach activator. The peroxygen bleaching compound and the bleach activator are in a molar ratio from about 1:1 to about 9:1. The detergent composition is stable, exhibits superior cleaning and contains a more biodegradable surfactant.
