An object of the present invention is to suppress and eliminate the occurrence of entanglement without performing an operation such as hand-passing on an object to be washed such as hair or fiber during washing and after washing with good foaming during washing. Provide a cleaning agent that can be used. The composition comprises (A) an anionic surfactant, (B) an aminopolyether-modified silicone having a polyoxyalkylene structure and satisfying the following formula (I), and (C) an organic acid. The mass ratio [(A) / (B)] of the component (A) to the component (B) is 25 or more, and the mass ratio [(A) / (C) of the component (A) to the component (C)] ] Is 1 or more and 3000 or less. 0.01 ≦ Si / AO ≦ 1.6 (I) [In formula (I), Si represents the number of moles of silicon atoms in component (B), and AO represents the average number of moles of oxyalkylene added in component (B). ] [Selection figure] None【課題】洗浄時の泡立ちが良好で、毛髪や繊維などの洗浄対象物に対し、洗浄時及び洗浄後においても手を通すなどの操作を行うことなく、絡まりの発生を抑制及び解消することができる洗浄剤を提供する。【解決手段】（Ａ）アニオン性界面活性剤、（Ｂ）下記式（Ｉ）を満たす、ポリオキシアルキレン構造を含有するアミノポリエーテル変性シリコーン、及び（Ｃ）有機酸を含有又は配合してなり、成分（Ａ）と成分（Ｂ）との質量比［（Ａ）／（Ｂ）］が２５以上であり、成分（Ａ）と成分（Ｃ）との質量比［（Ａ）／（Ｃ）］が１以上、３０００以下である洗浄剤。 ０．０１≦Ｓｉ／ＡＯ≦１．６ （Ｉ） 〔式（Ｉ）中、Ｓｉは成分（Ｂ）中のケイ素原子のモル数、ＡＯは成分（Ｂ）中のオキシアルキレン平均付加モル数を示す。〕【選択図】なし
