Title:
METHOD FOR PRODUCING DETERGENT PARTICLE GROUP
Document Type and Number:
WIPO Patent Application WO/2012/033006
Kind Code:
A1
Abstract:
The invention is a method for producing a detergent particle group, comprising: a step (A) of preparing base granules in which the contents of sodium carbonate, a water-insoluble inorganic salt, an acrylic acid-based polymer, and a surfactant fall within specific ranges, respectively, by spray-drying a slurry containing sodium carbonate, an acrylic acid-based polymer in which the ratio of the constituent unit of acrylic acid or a salt thereof to the total monomer constituent units constituting the polymer is from 90 to 100% by mole, and water, and optionally containing a water-insoluble inorganic salt; a step (B) of preparing a surfactant composition containing a surfactant including a predetermined amount of a nonionic surfactant and water in amounts within specific ranges; and a step (C) of mixing the base granules obtained in the step (A) and the surfactant composition obtained in the step (B) while substantially maintaining the form of the base granules.
