Abstract (en)
[origin: WO9413779A1] The invention concerns a granulated washing and cleaning agent, or a component thereof, the granulated material being roller-produced and its particles having a particular shape with an almost spherical macroscopic surface and a smooth microscopic surface as well as an almost monodisperse internal structure. The agent can be produced by a method in which, in a first stage, the powder-form starting materials are fed in and optionally mixed with liquid ingredients, the mixture then compressed in a second stage with the input of energy, and the resulting granulated materials compression-rolled against each other. The roller-granulation procedure is stopped by the addition of a finely particulate powder as soon as the particle-size distribution has reached the required maximum.
