Detergent compositions, including compositions for use in automatic dishwashing machines, are prepared by incorporating into the composition an intimate mixture of a nonionic surfactant and a silicone-containing suds suppressing agent. The compositions have reduced or controlled sudsing characteristics even after extended storage periods. The use of preferred self-emulsified silicone suds suppressors permits the production of low-sudsing spray-dried detergent granules without necessitating separate incorporation of the suds suppressors.

Detergent compositions containing ethoxylated nonionic surfactants and

A granular detergent composition for use in automatic dishwashing machines is prepared by forming a dry mix of an alkali metal condensed phosphate and an anhydrous alkali metal silicate of small particle size and agglomerating the dry mix with a silicate solution. Conventional surfactants can be included in the composition. The process is particularly suited to the preparation of automatic dishwashing machine detergents having relatively low levels of phosphate builders.

Process for preparing detergent compositions

Concentrated, essentially homogeneous, low-sudsing liquid detergent compositions containing a mixture of nonionic surfactants, anionic surfactants, and a self-emulsified silicone suds controlling agent.

Liquid detergent compositions containing a self-emulsified silicone suds

Detergent compositions containing water-insoluble aluminosilicate ion exchange materials, organic surface-active agents and a minor amount of silicate solids. The aminosilicate ion exchange materials are characterized by the speed and efficiency with which they are capable of removing hardness ions from the washing liquor. A minor amount of sodium silicate solids is used to provide effective corrosion inhibition and crispness to the detergent granules. The instant compositions are capable of providing, during conventional laundry cleaning operations, superior performance, particularly appearance benefits resulting from their effective anti-deposition properties.
