Spray-dried granules of high apparent density

Process for the production of surfactant-containing granulates

Continuous granulation process

Granular adsorbent having improved flushing properties

To produce granular, free-flowing detergents containing sodium metasilicate, pentasodium triphosphate or zeolite NaA or a triphosphate/zeolite mixture, at least two of the components are first agglomerated and mixed as a granular preagglomertate with other components present in powder form and compacted by means of rolls, the pressure limit beyond which no further compaction is obtained not being significantly exceeded. The compactate is then size-reduced to the desired particle size.

Process for the production of free-flowing alkaline detergents by

Stabilized aqueous zeolite A suspensions containing a nonionic surfactant as a stabilizer and an anionic surfactant as a stabilizer auxiliary are improved by using at least one sulfated C.sub.10-20 alcohol or substituted alcohol as the stabilizer auxiliary. In a further embodiment, an acid salt may be added to the suspension to adjust the pH to below 12.
