Abstract (en)
[origin: DE19501269A1] Water-soluble builder substances are to be prepared for the partial or complete replacement of zeolith in washing or cleaning agents. In addition, said water-soluble builder substances are also to be capable of absorbing constituents of washing or cleaning agents which are liquid to waxy at the operating temperature. Thus extruded washing or cleaning agents and a process for producing them is to be prepared which contain the water-soluble builder substances to the extent where zeolith may be partly or completely excluded not only for application but also for processing reasons, These aims are achieved by spray-dried amorphous alkaline silicate compounds with secondary washing power and a mol ratio of M2O : SiO2 (M = alkaline metal) or between 1:1.5 and 1:3.3, containing anionic tensides in proportions of 0.5 to less than 30 wt.%.
