PROBLEM TO BE SOLVED: To provide a method for producing a powdery detergent composition for clothing in which the classification of a detergent particle group due to vibration is suppressed, and the bubbling during the time of hand-washing is good.SOLUTION: Provided is a method for producing a powdery detergent composition for clothing including step 1: a step for preparing a slurry by mixing anionic surface active agent, an alkali agent and water, step 2: a step for preparing an aqueous solution containing water-soluble magnesium salt by mixing water-soluble magnesium salt and water, and step 3: a step for preparing a detergent particle group by spraying and drying the slurry obtained in step 1 and the aqueous solution obtained in step 2 by means of separate nozzles within the same spraying-drying tower.SELECTED DRAWING: None 【課題】振動による洗剤粒子群の分級が抑制され、手洗い時の泡立ちが良好な衣料用粉末洗剤組成物の製造方法を提供すること。【解決手段】工程１：陰イオン界面活性剤、アルカリ剤及び水を混合しスラリーを調製する工程、工程２：水溶性マグネシウム塩と水を混合し、水溶性マグネシウム塩を含有する水溶液を調製する工程、及び工程３：工程１で得られたスラリーと、工程２で得られた水溶液を、同一の噴霧乾燥塔内において別々のノズルで噴霧して乾燥させ、洗剤粒子群を調製する工程、を含む、衣料用粉末洗剤組成物の製造方法。【選択図】なし
