ABSTRACT:
Silane-Zeolite composites are incorporated into phosphate free detergents as builders. The use of such composites allows compositional improvements and results in certain process advantages when compared to detergents utilizing plain zeolites as phosphate replacements. Hydrated zeolites which have been treated with functionally hydrophilic silanes do not agglomerate during incorporation into detergents. In addition, use of the silane-zeolite composite allows use of increased amounts of both the zeolite and silicate solids as builders in detergents.
