ABSTRACT:
A method for producing alkali metal polysilicate complexes and their use as builders in detergents is disclosed. The polysilicates are produced by hydrothermally reacting, under certain controlled conditions, an aqueous dispersion of finely-divided silica, an alkali metal hydroxide and a sulfate salt of an alkali metal. The synthesized reaction mixture is then spray dried and the solid product fractured, pulverized and agitated in a rotating drum to form a product having particularly advantageous properties. The products of the invention can be used in adhesives, in the production of silica gel, in textiles and the like. However, their use as builders in detergents and in combination with known anionic, nonionic and amphoteric surface active compounds (surfactants) is disclosed and claimed.
