ABSTRACT:
A process for the manufacture of a free flowing granular dishwasher detergent having enhanced chlorine stability over extended periods of shelf life is disclosed. The process comprises mixing in a ventilated vessel, a dry mixture of sodium tripolyphosphate and chlorinated trisodium phosphate. The ratio of the volume of the dry mixture and the volume of the vessel is between about 1:25 and 1:8. An aqueous solution of silicate is sprayed onto the dry mixture to form an agglomerate during hydration of the sodium tripolyphosphate. The formed agglomerate is sprayed with a nonionic surfactant. The treated agglomerate is coated with a silicate. The coated agglomerate is mixed in the vessel while being discharged from the vessel. The silicate coated agglomerate inhibits chlorine loss from the dishwasher detergent over extended periods.
