1. A liquid detergent composition comprising:

  • 2% to 16% by weight, based on the total weight of the liquid detergentcomposition, of a surfactant system comprising a C12-18 alkyl sulfate anionic detersive surfactant and a linear C11-13 alkylbenzene sulfonate anionic detersive surfactant;

    3% to 6% by weight, based on the total weight of the liquid detergent composition, of detergency builders, the detergency builders comprising at least one aluminosilicate builder and one or more phosphate builders selected from the group consisting of sodium tri-polyphosphate, sodium orthophosphate, sodium pyrophosphate, and mixtures thereof,wherein 60% to 80% by weight of said detergency builders consists of sodium pyrophosphate, the liquid detergent composition having a density of from 800 g/l to 1300 g/l and a viscosity of from 500 cps to 3000 cps when measured at a shear rate of 20 s
