Abstract: 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.

Abstract: A simple process for producing, in high yield, detergent particles which contain a surfactant composition and the average particle diameter and particle size distribution of which fluctuate little with varying amounts of the surfactant composition incorporated and can be easily controlled by selecting appropriate base granules. The process comprises the step (I) of mixing 100 parts by weight of base granules as a surfactant support which have an average particle diameter of 150 to 500 mu m, a bulk density of 400 g/L or higher, and a particle strength of 50 kg/cm or higher Äingredient (a)Ü with 15 to 100 parts by weight of a surfactant comoposition Äingredient (b)Ü, under such conditions that the ingredient (a) does not substantially collapse, to obtain a mixture; and the step (II) of mixing 100 parts by weight of the mixture with 5 to 100 parts by weight of a fine powder while substantially maintaining the state of the ingredient (a) containing the ingredient (b). The detergent particles thus obtained have a degree of particle growth of 1.5 or lower and a bulk density of 500 g/L or higher.
