The present invention, creaminess of lather and foam, to the finger as property at the time of rinsing both excellent, and cans to the hair after drying moist, both grant-sensitive refreshing the scalp after drying, to provide a superior shampoo composition also to temporal stability. Shampoo compositions Ashirumechiru - - alanine taurine salt component (a) 3-30% by weight of the formula (1), equation (2) or amphoteric surface active agents represented by formula (3) ( component b) 3 to 30 wt%, the cationic polymer (c) component 0.03 to 3% by weight, and water to the component (d) is contained 37 to 94 wt%, (a) component and the component (b) ratio of the mass (a) / (b) is 0.2 to 3. [Formula 1] (R1CO is .M to an acyl group having 8 to 22 carbon atoms is an alkali metal, alkanolamine or basic amino acids.) ## STR2 ## (wherein, alkyl having 8 to 22 carbon atoms R2 a group or alkenyl group.) embedded image (in the formula, R3CO is .n to an acyl group having 8 to 22 carbon atoms are shown 1~3.)本発明は、泡立ちや泡のクリーミー性、すすぎ時の指通り性にともに優れ、かつ乾燥後の毛髪にはしっとり感、乾燥後の頭皮にはさっぱり感をともに付与し、経時安定性にも優れたシャンプー組成物を提供する。シャンプー組成物は、式(1)で表されるアシルメチル-β-アラニンのタウリン塩(a)成分を3~30質量%、式(2)または式(3)で表される両性界面活性剤(b)成分を3~30質量%、カチオン化ポリマー(c)成分を0.03~3質量%、および水(d)成分を37~94質量%含有し、(a)成分と(b)成分の質量比(a)/(b)が0.2~3である。【化1】(R1COは炭素数8~22のアシル基を示す。Mはアルカリ金属、アルカノールアミンまたは塩基性アミノ酸を示す。)【化2】(式中、R2は炭素数8~22のアルキル基もしくはアルケニル基を示す。)【化3】(式中、R3COは炭素数8~22のアシル基を示す。nは1~3を示す。)
