    • The present invention relates to a process for preparing uni-core detergent particles having a degree of particle growth of 1.5 or less and a bulk density of 500 g/L or more, comprising the steps of (A-I) mixing base particles for supporting a surfactant which have an average particle size of from 150 to 500 &mgr;m and a bulk density of 400 g/L or more [Component (a)] with a surfactant composition [Component (c)]; (A-II) mixing a mixture obtained in Step (A-I) with a powdery builder [Component (b)] of which primary average particle size is from 3 to 30 &mgr;m; and (A-III) mixing a mixture obtained in Step (A-II) with a fine powder [Component (d)] of which primary average particle size is smaller than that of Component (b). By using the process of the present invention, the uni-core detergent particles which are excellent in the dissolubility and the flowability properties can be prepared.
    • 本发明涉及一种制备颗粒生长度为1.5以下,体积密度为500g / L以上的单核洗涤剂粒子的方法,其特征在于,包括(A1)混合用于担载表面活性剂的基础粒子 具有表面活性剂组合物[组分(c)]的平均粒度为150至500μm,堆积密度为400g / L或更高[组分(a)]]。 (A-II)将步骤(A-I)中获得的混合物与一次平均粒径为3-30μm的粉末助洗剂[组分(b)]混合; 和(A-III)将步骤(A-II)中获得的混合物与一次平均粒径小于组分(b)的细粉末[组分(d)]混合。 通过使用本发明的方法,可以制备溶解性和流动性优异的单核洗涤剂颗粒。
