    • There is disclosed a process for preparing highly absorptive granular alkali metal nitrilotriacetate by contacting NTA powder with an aqueous alkali metal silicate solution. A granular product having a majority of the granules, by weight, in the -12 to +80 mesh size range, which have a density of at least about 0.60 g/cc and an absorptivity in the absorptivity test in the range of above 7 ml/100 g is produced by contacting alkali metal nitrilotriacetate with an alkali metal silicate solution, mixing the material to granulate it and then drying the granules. A granular product having a density of at least about 0.60 g/cc, fewer than 15% fine material and an absorptivity in the range of from about 7-20 ml/100 g is produced.

    • A process for preparing high density detergent compositions is provided. The process comprises the steps of: (a) continuously mixing a detergent surfactant paste and dry starting detergent material into a high speed mixer/densifier to obtain detergent agglomerates, wherein the ratio of the surfactant paste to the dry detergent material is from about 1:10 to about 10:1; (b) mixing the detergent agglomerates in a moderate speed mixer/densifier to further densify and agglomerate the detergent agglomerates; and (c) drying said detergent agglomerates so as to form the high density detergent composition. The dry detergent material may contain a builder material including a crystalline microstructure in which a carbonate anion, a calcium cation and at least one water-soluble cation are contained. The process may include one or more additional processing steps such as adding a coating agent such as the builder material described herein after the moderate speed mixer/densifier to facilitate and control agglomeration.
    • 提供了制备高密度洗涤剂组合物的方法。 该方法包括以下步骤:(a)将洗涤剂表面活性剂浆料和干燥起始洗涤剂材料连续混合到高速混合器/增密器中以获得洗涤剂附聚物,其中表面活性剂浆料与干洗涤剂材料的比例为约1: 10至10:1; (b)在中速混合器/增密器中混合洗涤剂附聚物以进一步致密化并附聚洗涤剂附聚物; 和(c)干燥所述洗涤剂附聚物以形成高密度洗涤剂组合物。 干燥的洗涤剂材料可以含有包含其中含有碳酸根阴离子,钙阳离子和至少一种水溶性阳离子的结晶微结构的助洗剂材料。 该方法可以包括一个或多个另外的加工步骤,例如在中速混合器/增密器之后添加涂覆剂,例如本文所述的助洗剂材料,以促进和控制附聚。

    • A process for preparing detergent agglomerates for a detergent composition is provided. The process comprises the steps of: (a) providing a non-linear viscoelastic surfactant paste including, by weight of the surfactant paste, from about 70% to 95% of a detersive surfactant and from about 5% to about 30% of water; (b) regulating the amount of sodium carbonate in the surfactant paste such that the surfactant paste has a Maximum Shear Rate of at least 20 sec.sup.-1 so that the surfactant paste is processable; (c) charging the surfactant paste into a high speed mixer/densifier; (d) inputting from about 1% to about 70% by weight of a detergency builder into the high speed mixer/densifier; and (e) agglomerating the surfactant paste and the builder by treating the surfactant paste and the builder initially in the high speed mixer/densifier and subsequently in a moderate speed mixer/densifier so as to form detergent agglomerates.
