    摘要: A process for producing free-flowing granules comprising the steps of (a) drying with superheated steam an aqueous mixture containing at least one surfactant selected from the group consisting of anionic surfactants and nonionic surfactants to form carrier granules having a porous inner structure, and (b) impregnating the porous inner structure of the carrier granules with an aqueous coating composition selected from the group consisting of wetting agents, detergents, cleaning agents, and mixtures thereof, to form an impregnated carrier granule.

    摘要: Anionic surfactant concentrates in the form of solid free-flowing powders and/or granules which may also be present as compounds in admixture with other auxiliaries and/or useful materials suitable for use in detergents and/or cleaning products and which have apparent densities of at least about 150 g/l are produced by hot drying of the water-containing preparations with superheated steam as the drying gas. Preferred apparent densities are above about 200 g/l and are preferably at least about 350 g/l. In addition, the pourable and free-flowing material is preferably in the form of a substantially dust-free material through the presence of dust-binding auxiliaries and/or useful materials and/or by regulation of the residual water content. In one preferred embodiment, the anionic surfactant concentrate is in the form of porous carrier beads with an absorbent porous inner structure.
