  • Patent number: 5009804
    Abstract: Granular laundry detergent compositions are disclosed comprising two separate surfactant-containing components, optionally together with other dry mixed ingredients. The first component, preferably spray dried, contains a slowly-dissolving surfactant in combination with an organic and/or inorganic salt. The surfactant is preferably a long chain (C.sub.16+) alkyl sulfate or a long chain fatty acid salt. The second component comprises one or more surfactants of higher solubility rate and is preferably formed by agglomeration. Satisfactory release of the compositions from the dispensing compartment of an automatic washing machine can be maintained even when the compositions are of a concentrated high density type.
