PROBLEM TO BE SOLVED: To provide an aqueous hair detergent which is excellent in the slipperiness of hair at the time of cleaning and rinsing and can impart moist feeling to the hair after drying, even if the hair is damaged.SOLUTION: The present invention relates to the aqueous hair detergent which contains components (A) to (C) and water and has a pH of 2 to 6 when diluted by 20 times. (A) an anionic surfactant (B) a cellulose ether containing a cationic group which has a main chain derived from anhydroglucose represented by formula (1) and in which the substitution degree of a cationized oxyalkylene group per unit of the anhydroglucose is 0.01 to 1.0, the substitution degree of a glycerol group is 0.5 to 5.0, and the substitution degree of a specific group containing a hydrocarbon group is 0 to 0.2 and (C) a specific monoalkyl glyceryl ether or monoalkenyl glyceryl ether (R1 to R3 each independently represent a cationized oxyalkylene group, a glycerol group, or H n is a number of 100 to 12000).COPYRIGHT: (C)2015,JPO&INPIT【課題】傷んだ毛髪であっても、洗浄時、及びすすぎ時の毛髪のすべり性にすぐれ、乾燥後の毛髪にしっとり感を与えることができる水性毛髪洗浄剤の提供。【解決手段】成分(A)~(C)及び水を含有し、20倍希釈時のpHが2~6である水性毛髪洗浄剤。(A)アニオン界面活性剤;(B)式(1)で表されるアンヒドログルコース由来の主鎖を有し、該アンヒドログルコース単位当りのカチオン化オキシアルキレン基の置換度が0.01~1.0であり、グリセロール基の置換度が0.5~5.0迄であり、炭化水素基を含有する特定の基の置換度が0~0.2であるカチオン性基含有セルロースエーテル;(C)特定のモノアルキルグリセリルエーテル又はモノアルケニルグリセリルエーテル(R1~R3は各々独立にカチオン化オキシアルキレン基、グリセロール基又はH;nは100~12000の数である。)【選択図】なし
