Abstract

A washing and cleaning agent shaped body in the form of a granulate, extrudate, agglomerate, or tablet, containing fine microparticles that contain one or more washing or cleaning agent components, wherein the fine microparticles form the shaped body as such or are present within it. The washing or cleaning agent component is selected from surfactants, fragrances, dyes, enzymes, enzyme stabilizers, builders, substances to adjust the pH, bleaches, bleach activators, silver protectants, soil-repelling substances, optical brighteners, antiredeposition agents, disintegration auxiliaries, and mixtures thereof. At least 10% of the fine microparticles, based on the total number of microparticles, have a particle size distribution of ≦20 μm.
