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.
