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. A polyoxyalkylene structure having (A) at least one member selected from the group consisting of alkylsulfines, alkylhydroxysulfines, and nonionic surfactants, and (B) a polyoxyalkylene structure satisfying the following formula (I): A detergent containing or blended with an aminopolyether-modified silicone, wherein the mass ratio [(A) / (B)] of component (A) to component (B) is 0.1 or more and 1000 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)アルキルスルタイン、アルキルヒドロキシスルタイン、及びノニオン性界面活性剤からなる群から選ばれる1種以上、及び、(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0.1以上、1000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
