PROBLEM TO BE SOLVED: To provide a liquid clothing detergent composition excellent in antibacterial activity, liquid stability, and resoiling-preventing property.SOLUTION: A liquid clothing detergent composition contains a component (A): a nonionic antibacterial agent, a component (B): a surfactant, and a component (C): a propylene oxide adduct of a C1-5 alcohol. The content of the component (B) is 30 mass% or more based on the total mass of the liquid clothing detergent composition. The component (B) contains a nonionic surfactant and an anionic surfactant. The content of the nonionic surfactant is higher than the content of the anionic surfactant.SELECTED DRAWING: NoneCOPYRIGHT: (C)2018,JPO&INPIT【課題】抗菌活性、液安定性、再汚染防止性に優れる衣料用液体洗浄剤組成物を提供すること。【解決手段】(A)成分:ノニオン系抗菌剤と、(B)成分:界面活性剤と、(C)成分:炭素数1~5のアルコールのプロピレンオキシド付加物と、を含有し、前記(B)成分の含有量が、衣料用液体洗浄剤組成物の総質量に対し、30質量%以上であり、前記(B)成分は、ノニオン界面活性剤と、アニオン界面活性剤とを含有し、前記ノニオン界面活性剤の含有量が、前記アニオン界面活性剤の含有量よりも多い、衣料用液体洗浄剤組成物。【選択図】なし
