Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method for producing a concentration type detergent composition excellent in storage stability in a stirring tank having stirring blades, and a concentration type detergent composition produced by the method and excellent in storage stability.SOLUTION: Provided is a method for producing the detergent composition having: a process (1) where components including an alkali agent (A), a chelate agent (B), a nonionic surfactant (C), 8 to 22C primary alcohol (D), specified alkylether sulfate ether or its salt (E) and water (F) are introduced into a stirring tank having stirring blades; and a process (2) where the stirring blades are rotated to mix the respective components. In the process (1), the ratio of the components introduced into the stirring tank are respectively specified amounts, and the alkali detergent composition for a steel sheet being a dispersed body in which oil droplets of the (C) with a particle diameter below 50 μm are dispersed into a phase including the water (F).SELECTED DRAWING: None
【課題】攪拌翼を有する攪拌槽で、保存安定性に優れる濃縮型の洗浄剤組成物の製造方法及びその方法で製造される、保存安定性に優れる濃縮型の洗浄剤組成物の提供。【解決手段】アルカリ剤(A)、キレート剤(B)、非イオン性界面活性剤(C)、炭素数8〜22の一級アルコール(D)、特定のアルキルエーテル硫酸エステル又はその塩(E)及び水(F)を含む成分を、攪拌翼を有する攪拌槽に導入する工程(1)、及び攪拌翼を回転させて各成分を混合する工程(2)を有する当該洗浄剤組成物の製造方法であって、工程(1)において攪拌槽に導入する前記成分の割合がそれぞれ特定量であり、前記鋼板用アルカリ洗浄剤組成物が、水(F)を含む相に粒子径が50μm未満の(C)の油滴が分散した分散体である鋼板用アルカリ洗浄剤組成物の製造方法。【選択図】なし |
