ABSTRACT:
Poorly flowing or caked detergent powders which include synthetic organic detergent, inorganic salt and moisture (with at least some of the moisture hydrating the salt) are reconditioned by mixing therewith a small proportion of hydratable molecular sieve zeolite, preferably of an initial moisture content of less than 3%. The reconditioned powders are free flowing, non-tacky and non-caking and the compositions resulting, rather than being less effective, have additional water softening and building properties due to the presence of the molecular sieve zeolite. Preferably, the molecular sieve zeolite employed is anhydrous and of type 4A and the detergent composition is a heavy duty non-phosphate product.
