<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a granular detergent composition excellent in solubility to water even when the content of a surfactant is in a low concentration less than 30 mass%. <P>SOLUTION: The method of manufacturing the granular detergent composition containing less than 30 mass% of the surfactant, an inorganic builder, and an alkali agent includes: a pretreatment process for mixing the surfactant, the inorganic builder, and the alkali agent to prepare the mixture having a water content below 15 mass%; and a granulation process for blending a sulfate hydrate and an organic chelator containing a nitrogen atom in a molecular into the mixture and granulating the resultant mixture. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
