Granules for carrying surfactant and method for producing the same

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.
