Abstract (en)

[origin: WO9401526A1] When preparing powdered or granulated detergent composition having a high apparent density, an ulterior treatment is required in order to improve its solubility. For that purpose, the prefabricated powder or granulate having over 500 g/l apparent density is contacted while stirring with a liquid or solid, hydrophobic and/or water-insoluble component which is not a zeolite. The weight ratio between the prefabricated powder and the liquid or solid, hydrophobic and/or water-insoluble treatment agent is set between 20 : 1 and 2000 : 1.
