<p>Granular, phosphate-free detergents based on synthetic anionic surfactants, fine-particle, water-insoluble builder substances and fillers contain, to increase the fracture resistance and surface smoothness, 0.5 to 10 % by weight of an alkali metal silicate and 0.5 to 10 % by weight of a polyethylene glycol. Zeolite NaA is preferably employed as water-insoluble builder substance. The detergent granules can be produced by mixing the components, where appropriate with the addition of water, and extruding the mixture, chopping and, where appropriate, compressing to granules.</p> |
