Alkaline dishwasher detergent composition having a specific critical pH, and a relatively high level of available chlorine, buffered with trisodium phosphate, containing a tripolyphosphate or pyrophosphate sequestering builder, and having a relatively high level of surfactant. The detergent composition is substantially free of highly alkaline materials and organic builders and preferably contains 2.0r alkali metal silicate and/or a preferred C.sub.17 -C.sub.19 polyethoxylate surfactant.

Alkaline dishwasher detergent

Granular detergent compositions containing alkali metal polyphosphates are prepared by spraying an aqueous sodium silicate solution onto anhydrous alkali metal polyphosphates and optionally onto other dry ingredients, said aqueous sodium silicate solution containing from about 2% to about 20% by weight of a hydratable salt.

Agglomeration process for making granular detergents

Alkaline dishwasher detergent composition having a specific critical pH, and, preferably, a relatively high level of available chlorine, buffered with trisodium phosphate, containing a tripolyphosphate or pyrophosphate sequestering builder, and having a relatively high level of surfactant. The detergent composition is substantially free of highly alkaline materials and organic builders and preferably contains 2.0r alkali metal silicate and/or a preferred C.sub.17 -C.sub.19 polyethoxylate surfactant.

Bleach-free detergent compositions for use in automatic dishwashers comprising an alkoxylated nonionic surface-active agent and a sulfonated aromatic compatibilizing agent. Preferred nonionic surfactants include ethoxylated nonionics and preferred compatibilizing agents can be selected from xylene-, toluene-, cumene-, benzene-, trimethylbenzene-, ethylbenzene- and ethylmethylbenzenesulfonate. The instant compositions possess enhanced anti-redepositon properties for soils composed of grease and grease-protein complexes thereby providing impeccably cleaned objects which are virtually free of spots and streaks.
