Zusammenfassung:To provide a liquid detergent free of isothiazoline-based preservatives widely used in a detergent composition having almost-neutral liquidity.SOLUTION: A liquid detergent composition contains component (A): a nonionic surfactant, component (B): a non-soap-based anionic surfactant, and component (C): an organic solvent represented by general formula (c1). The content of the component (C) is 3.5 mass% or more relative to the total mass of the liquid detergent, and the total surfactant content is 30 mass% or less relative to the total mass of the liquid detergent. As a preservative, neither isothiazolone-based organic sulfur compounds nor benzisothiazolin-based organic sulfur compounds are used. (In the general formula (c3), R31-R33 independently represent a hydrogen atom or a C1-3 alkyl group, R34 is a hydrogen atom or an acetyl group).SELECTED DRAWING: None 【課題】液性が中性付近の洗浄剤組成物において広く使用されているイソチアゾリン系の防腐剤を含まない液体洗浄剤を提供。【解決手段】(A)成分:ノニオン界面活性剤と、(B)成分:非石鹸系アニオン界面活性剤と、(C)成分:下記一般式(c1)で表される有機溶剤、を含有し、前記(C)成分の含有量が液体洗浄剤の総質量に対して3.5質量%以上であり、総界面活性剤量が液体洗浄剤の総質量に対して30質量%以下であり、防腐剤としてイソチアゾロン系の有機硫黄化合物、ベンズイソチアゾリン系の有機硫黄化合物を含まない、液体洗浄剤組成物。[化1](一般式(c3)中、R31~R33は、それぞれ独立に水素原子又は炭素数1~3のアルキル基であり、R34は水素原子又はアセチル基である。)【選択図】なし
