The present invention provides a liquid detergent composition, which can realize delicate texture, good foam quality when closely contacting with the skin and good in applying on the skin, in order to allow the foam to be applied evenly on the skin during cleaning, and good use feeling for softening skin after cleaning. A liquid detergent composition comprises the following ingredients (A) and (B): (A) N-acyl glutamate or salt thereof having a carbon number of 8-18 and (B) N-acyl aspartic acid or salt thereof having a carbon number of 8-18, and (C) amphoteric surfactants, in which the content of the ingredients (A) and (B) is in total more than 2% and less than 18% of mass, and the content of the ingredient (C) is below 2.5% of mass. A ratio ((S)/{(A)+(B)}) of mass of N-acyl glutamic acid or salt thereof and N-stearyl acyl aspartic acid or salt (S) to mass of the ingredients (A) and (B) is below 0.1, and a ratio ((B)/{(A)+(B)}) of mass of the ingredient (B) to mass of the ingredients (A) and (B) is more than 0.3 and less than 0.6.本發明提供一種液體洗淨劑組成物,其可實現紋理細膩、儘管泡沫向肌膚之密接性良好但亦兼顧泡沫向肌膚之推開性良好的良好泡質,而洗淨時使泡沫遍及皮膚各處,並且帶來洗完後之皮膚較為柔軟之良好使用感。一種液體洗淨劑組成物,其含有下述成分(A)及(B):(A)具有碳數8~18之醯基之N-醯基麩胺酸或其鹽、及(B)具有碳數8~18之醯基之N-醯基天冬胺酸或其鹽、以及(C)兩性界面活性劑,且成分(A)與成分(B)之含量之合計為2質量%以上且18質量%以下,成分(C)之含量為2.5質量%以下,N-硬脂醯基麩胺酸或其鹽及N-硬脂醯基天冬胺酸或其鹽之含量之合計(S)占成分(A)與成分(B)之含量之合計的比率以質量比((S)/{(A)+(B)})計為0.1以下,且成分(B)之含量相對於成分(A)與成分(B)之含量之合計的質量比((B)/{(A)+(B)})為0.3以上且0.6以下。
