PURPOSE:To shear and atomize a cationic surface active agent by providing a valve which forms a very narrow slit by water pressure in a piping in which water flows and supplying continuously the cationec surface active agent from a nozzle provided in porximity on the upper stream side of the valve into the water. CONSTITUTION:A valve 6 which forms a very narrow slit by water pressure is disposed in a piping 1 in which water flows, and a cationic surface active agent is continuously supplied from a nozzle 2 provided in proximity on the upper stream side of said valve 6 into the water. More specifically, the cationic surface active agent is supplied in the position near the slit valve and therefore the cationic surface active agent contacts or mixes with the water prior to a dispersion treatment and forms a liquid crystal structure, by which the formation of viscous liquid is avoided as far as possible and since the uniform shearing is made possible by the valve 6, the atomized material having the grain size distribution smaller than that by a stirring blade is obtd.
