Zusammenfassung:To provide a liquid detergent composition for clothing having excellent urine odor removal effect and defoaming properties.SOLUTION: The present invention provides a liquid detergent composition having a nonionic surfactant (A) represented by R-X-(EO)-Rand a nonionic surfactant (B) represented by R-X-[(EO)/(AO)]-R, and an organic carboxylic acid (C), where, a mass ratio of (B)/(A) is 0.35 or less, and pH(25°C) is 2-6.5. Ris a C8-18 hydrocarbon group, Ris a C8-24 hydrocarbon group, X, Xeach are -O-, -C(O)O- or -C(O)NH-, R, Reach are a hydrogen atom, a C1-6 alkyl group, or a C2-6 alkenyl group, EO is an oxyethylene group, AO is at least one of an oxypropylene group and an oxybutylene group, n is 3-20, s is 1-30, t is 1-20.SELECTED DRAWING: None 【課題】尿臭除去効果及び消泡性に優れた衣料用液体洗浄剤組成物の提供。【解決手段】R1−X1−(EO)n−R2で表されるノニオン界面活性剤(A)、R11−X2−[(EO)s/(AO)t]−R12で表されるノニオン界面活性剤(B)、及び有機カルボン酸(C)を含み、(B)/(A)の質量比が0.35以下、pH(25℃)が2〜6.5である衣料用液体洗浄剤組成物。R1は炭素数8〜18の炭化水素基、R11は炭素数8〜24の炭化水素基、X1、X2は−O−、−C(O)O−または−C(O)NH−、R2、R12は水素原子、炭素数1〜6のアルキル基、または炭素数2〜6のアルケニル基、EOはオキシエチレン基、AOはオキシプロピレン基またはオキシブチレン基の少なくとも一方、nは3〜20、sは1〜30、tは1〜20。【選択図】なし
