ABSTRACT:
Hydrophilic, silane-zeolite compositions, their preparation, properties and applications are disclosed. These unique composites are formed by condensing a hydrophilic silane onto the surface of a hydrated zeolite. The properties of the silane-zeolite composite are surprisingly similar to those of the zeolite without the surface modification of the silane. These composites are useful in numerous applications of zeolite, particularly in aqueous environments. The composites are particularly suited to be included in detergent compounds as the builder since they do not agglomerate with other detergent ingredients as do zeolites.
