Disintegrable detergent builder agglomerate

Abstract From the Canadian patent

Agglomerates of water insoluble builder molecular sieve zeolites are made by tumbling or otherwise suitably mixing very finely divided ion exchanging zeolite powder and a water soluble binder such as starch, pre-, ferably in the presence of a small amount of moisture sufficient to promote desirable agglomeration of the finely dived ion exchanging zeolite particles and the binder into essentially spherical particles preferably, in the 6 to 140 mesh range. The agglomerates are readily disintegrated when agitated in water and rapidly release the separated very finely divided insoluble builder particles to allow them to remove hardness ions from the water. The dispersible and disintegrable …
