A granular detergent composition is provided in which from about 0.01 % to about 60 % by weight of the detergent is a surfactant system having an electrolyte rich surfactant zone and a electrolyte poor surfactant zone. The electrolyte rich zone includes an electrolyte and an anionic surfactant which is not an alkyl sulfate surfactant wherein the electrolyte comprises at least about 20 % by weight of the electrolyte rich zone. The electrolyte poor zone includes an electrolyte and an alkyl sulfate surfactant wherein the electrolyte comprises less than about 20 % by weight of the electrolyte poor zone.
