Abstract: A process for making a high solids content Zeolite A-alkylbenzene sulfonate detergent composition suitable for use in making spray dried detergent compositions includes manufacturing Zeolite A by a hydrogel, clay conversion, natural silica or equivalent process so that the Zeolite A is present in an aqueous medium containing alkali metal hydroxide in solution therein, separating a substantial proportion of the aqueous medium from the Zeolite A so as to produce Zeolite A particles, usually in cake form, containing excess alkali metal hydroxide solution on particle surfaces and occluded by such particles, and at least partially neutralizing said excess alkali metal hydroxide with a high concentration aqueous alkylbenzene sulfonic detergent acid, such as a sulfonic detergent acid resulting from oleum sulfonation or sulfur trioxide sulfonation of a linear higher alkylbenzene.

Abstract: A process for producing free flowing spray dried base builder beads comprising inorganic detergent builders. The builder beads comprise alkali metal phosphate, alkali metal silicate and water. The alkali metal phosphate component includes a hydrated and an anhydrous portion. Relatively large amounts of liquid or liquifiable detergent ingredients such as surface active agents etc. can be applied to the base beads after spray drying, without destroying their free flowing properties.

Abstract: 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, preferably in the presence of a small amount of moisture sufficient to promote desirable agglomeration of the finely divided 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 agglomerates are especially useful in heavy duty detergent compositions wherein the zeolite of the agglomerate provides all or a substantial proportion of the builder content.
