ABSTRACT OF THE DISCLOSURE An aqueous pumpable stable suspension of a water- insoluble silicate capable of binding calcium ions which con- tains, relative to the total weight of the aqueous suspension, A) as a silicate capable of binding calcium, 0.5 to 80 percent by weight of a finely divided, bound-water-containing, synthe- tically produced, water-insoluble compound having the general formula (Kat2/nO)x ? Me2O3 ? (SiO2)y (I), wherein Kat represents a cation which is exchangeable with calcium and has the valency n, x represents a number from 0.7 to 1.5, Me represents boron or aluminium and y a number from 0.8 to 6, and B) as the component having a dispersing effect it contains 0.5 to 6 percent by weight of a mixture of at least two different alkyl phenol ethoxylates having the formula Image (II) The component A can be specifically a zeolite A while the com- ponent B consists of two alkyl phenol ethoxylates having the formula II, wherein n = 2 to 7 and n = 8 to 15. The suspen- sion can be used for producing powdered detergents.
