Abstract (en)
[origin: WO9414946A1] A process is disclosed for preparing granulated washing and/or cleaning agents having an apparent density in a range from 600 to 1100 g/l. Also disclosed are granulated washing and/or cleaning agents produced by said process. In a first step, a basic granulate free of bleaching agent and substantially free of non-ionic surfactant is produced by granulation and/or spray drying, the basic granulate is then mixed during a first preparation step with bleaching agents and non-ionic surfactants while energy is supplied, and bleach activators and, optionally, other ingredients are then admixed in a second preparation step. If the admixture of bleaching agents and non-ionic surfactants is offset in time, and if energy is supplied at the same time, the apparent density of the washing and/or cleaning agents may be distinctly increased.
