Low-foam scouring powder

Granular adsorbent having improved flushing properties

An agglomerate containing sodium sulfate and as layer silicate, a synthetic layer silicate which has a smectite-like crystal phase, increased contents of bound alkali metal and silicate and a distinctly reduced swelling power compared with pure smectites. The agglomerate can take up significant quantities of an additional liquid component in its pores, resulting in a free-flowing agglomerate which outwardly feels dry. This high adsorption capacity may be used, for example, to take up a liquid detergent component which may then be mixed in combination with powder-form or granular detergent components to form a free-flowing detergent composition.

Porous layer silicate/sodium sulfate agglomerate

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

Process for reducing the viscosity of aqueous concentrates of anionic surfactants by adding thereto a small quantity of a compound containing polyglycol ether groups; and the aqueous concentrates prepared thereby.
