An aqueous slurry comprising an organic detergent, an alkali metal silicate and an alkali metal orthophosphate or an inert salt are dried to a low moisture content to form a detergent composition.

Process for preparing an orthophosphate-silicate detergent product

Detergent compositions utilizing alkali metal pyrophosphate as the principal detergency builder incorporate a phosphate builder mixture comprising from about 1% to about 15% by weight of the mixture of tripoly -- and higher polymeric phosphates and not more than 1% by weight of the mixture of orthophosphates Other types of builders both soluble and insoluble can also be present.

Builders and built detergent compositions

The present invention relates to detergent additive and detergent compositions containing an alkali metal ortho phosphate and silicas which are particularly effective in cleaning ability, whiteness maintenance, and in controlling water hardness.
