PROBLEM TO BE SOLVED: To produce a detergent composition for laundry good in fluidity by using a ribbon mixer. SOLUTION: As a result of intensive studies made by present inventors, et al. to solve the problems, it has been found that a detergent composition retaining excellent fluidity is obtained by regulating the order of addition of components constituting the detergent when producing the detergent composition comprising a specific silicate having high hygroscopicity, thus achieving the present invention. That is, the method for producing the detergent composition for the laundry is characterized as comprising preadding silicic acid anhydride in an amount of 0.5-5 mass % based on the detergent composition to an apparatus, then starting the stirring and mixing, adding and mixing other detergent constituent components, completing the spray of a liquid consisting essentially of a nonionic surfactant and subsequently adding a soap powder having >=50% soap content and >=0.5 g/mL bulk density and then a silicate in (1/1) to (1/3) molar ratio of SiO2/M2O (M denotes an alkali metal) in the order mentioned when producing the detergent composition by stirring and mixing the detergent constituent components while spraying the liquid consisting essentially of the nonionic surfactant.
