Granular detergent composition having an average bulk density of at least about 400 g/L and characterized by a rate of dispersion under stressed cold-water conditions as defined by the equation (1), where R is the residual undispersed detergent at any point in time, t, R is the long term residual undispersed detergent having a value of less than about 14 % of the total amount of an initial dosage of detergent, t is any single point in time, m is a stretching exponent having a value of less than about 2, DT is dispersion time having a value of less than about 0.5 and twash is the time of the wash cycle; and at least 90 % of the insoluble particulate residues of said granular detergent composition having a particle size of less than 15 mu m are provided. In preferred embodiments, the detergent composition has a rate of dissolution under stressed cold-water conditions as defined by the equation (2), where U is the fraction of undissolved surfactant at any point in time, t, U is the long term surfactant residual undissolved surfactant having a value of less than about 14 % of the total amount of an initial dosage of surfactant, t is any single point in time, n is a stretching exponent having a value of less than about 2, RT is dissolution time having a value of less than about 0.5 and twash is the time of the wash cycle. |
