PROBLEM TO BE SOLVED: To provide a liquid cleaning composition which realizes good foam quality having fine texture, good adhesion of foam to the skin and yet also good spread of foam to the skin, allows foam to spread over all parts of the skin in cleaning, and also leads to good use feeling that the skin is soft after cleaning.SOLUTION: A liquid cleaning composition contains a component (A): a N-acylglutamic acid having an acyl group with a carbon number of 8 to 18 or a salt thereof, and a component (B): a N-acyl aspartic acid having an acyl group with a carbon number of 8 to 18 or a salt thereof, where the total content of the component (A) and the component (B) is 2 mass% or more and 18 mass% or less, the proportion of the total content (S) of the N-stearoyl glutamic acid or a salt thereof and the N-stearoyl aspartic acid or a salt thereof in the total content of the component (A) and the component (B) is 0.1 or less as a mass ratio ((S)/{(A)+(B)}), and the mass ratio ((B)/{(A)+(B)}) of the component (B) content based on the total content of the component (A) and the component (B) is 0.3 or more and 0.6 or less.COPYRIGHT: (C)2014,JPO&INPIT【課題】きめが細かく、泡の肌への密着性がよいにもかかわらず泡の肌への伸びの良さが両立した良好な泡質を実現し、洗浄時において皮膚のすみずみまで泡を行きわたらせることを可能にするとともに、洗い上がりの皮膚が柔和である良好な使用感をもたらす液体洗浄剤組成物を提供する。【解決手段】成分(A)炭素数8~18のアシル基を有するN-アシルグルタミン酸又はその塩、及び成分(B)炭素数8~18のアシル基を有するN-アシルアスパラギン酸又はその塩を含有し、成分(A)と成分(B)の含有量の合計が2質量%以上18質量%以下であり、成分(A)と成分(B)の含有量の合計に占める、N-ステアロイルグルタミン酸又はその塩及びN-ステアロイルアスパラギン酸又はその塩の含有量の合計(S)の割合が質量比((S)/{(A)+(B)})で0.1以下であり、かつ成分(A)と成分(B)の含有量の合計に対する成分(B)の含有量の質量比((B)/{(A)+(B)})が0.3以上0.6以下である液体洗浄剤組成物。【選択図】なし
