PROBLEM TO BE SOLVED: To provide a detergent composition having conditioning effect and improved foam volume and foam quality.SOLUTION: There is provided a detergent using a polyaspartic acid derivative containing a unit represented by the formula (1) and a unit represented by a structure where bound carbon position of repeats of the formula (1) shifts one. (1), where R1 is H or a C1 to 6 monovalent hydrocarbon group, R2 is a C1 to 24 bivalent hydrocarbon group, R3 to R5 are monovalent hydrocarbon group having 1 to 24 H atoms or C atoms, R3 to R5 are each independently H or a C1 to 24 hydrocarbon group, R3 to R5 may bind each other to form a ring and X- is anion of organic or inorganic acid.SELECTED DRAWING: NoneCOPYRIGHT: (C)2017,JPO&INPIT【課題】コンディショニング効果を有し、泡量、泡質を改善した洗浄剤組成物の提供。【解決手段】式(1)で表される単位及び式(1)の繰り返しの結合炭素位置が一つずれた構造で表される単位を必須とするポリアスパラギン酸誘導体を用いる洗浄剤。〔R1はH又はC1~6の1価の炭化水素基;R2はC1~24の2価の炭化水素基;R3~R5は、H原子又はC原子数1~24の1価炭化水素基、R3~R5は夫々独立にH又はC1~24の炭化水素基、R3~R5は互いに結合して窒素原子を含む環を形成していてもよい;X-は有機又は無機の酸のアニオン〕【選択図】なし
