Abstract (en)

[origin: DE4435632A1] The object of the invention is to prepare washing or cleaning agents, especially washing agents with apparent densities of over 500 g/l, which contain water-soluble silicate builders superimposed on the crystalline layered disilicates in these compositions. This is achieved by agents containing anionic and non-ionic tenside, inorganic builders and possibly organic co-builders, in which the inorganic builder in these agents is a spray-dried and then compressed and ground silicate in quantities of over 10 wt.% and organic co-builders in quantities of 0 to under 20 wt.%.
