    • The present invention relates to particles for supporting a surfactant and a process for preparing the same. Further, the present invention relates to high-density detergent particles using the particles for supporting a surfactant, and a process for preparing the same. According to the present invention, there can be obtained particles for supporting a surfactant which are excellent in the supporting ability (supporting capacity/supporting strength) for the liquid surfactant composition, and particles for supporting a surfactant which are excellent in the absorption properties (supporting rate) for the liquid surfactant composition, by spray-drying a preparation liquid obtainable by a process comprising the steps of preparing a first preparation liquid comprising a solution or slurry comprising a water-soluble polymer and a water-soluble salt; and subjecting the first preparation liquid to a treatment of increasing a number of water-soluble salt particles, thereby preparing a second preparation liquid having an increased number of water-soluble salt particles, as compared to the number of water-soluble salt particles which are present in the first preparation liquid. Further, since the liquid surfactant composition is supported by the particles for supporting a surfactant, detergent particles which are excellent in detergent performance, quality and the like can be efficiently obtained.
    • 本发明涉及用于支持表面活性剂的颗粒及其制备方法。 此外,本发明涉及使用用于支撑表面活性剂的颗粒的高密度洗涤剂颗粒及其制备方法。 根据本发明,可以获得支撑液体表面活性剂组合物的支持能力(支撑能力/支撑强度)优异的表面活性剂用颗粒和吸收性优异的支撑表面活性剂的颗粒(支撑 速率),通过喷雾干燥可通过包括以下步骤的方法获得的制备液:制备包含水溶性聚合物和水溶性盐的溶液或浆液的第一制备液; 并且对第一制备液进行处理以增加数量的水溶性盐颗粒,从而制备具有增加数量的水溶性盐颗粒的第二制备液,与水溶性盐颗粒的数量相比, 存在于第一准备液中。 此外,由于液体表面活性剂组合物被用于支撑表面活性剂的颗粒负载,所以可以有效地获得洗涤剂性能,质量等方面优异的洗涤剂颗粒。
