精製水はイオン交換水の意味である。
また、実施例4と比較例6、7とを比較すると、同じカチオン性ポリマーであっても、本願と異なるポリマーでは、性能において劣ることがわかる。実施例7から10のようにコカミドプロピルベタイン(カルボベタイン)とラウリルヒドロキシスルホベタイン(スルホベタイン)とを併用することで、泡性能が向上すると共に、感触も向上している。
表5に示す組成の毛髪洗浄剤組成物を常法により製造し、pHを水酸化ナトリウムで6.0(20℃)に調整し、泡量、泡質、洗浄時、すすぎ時に加えて、WET時、DRY時の毛髪についても、同様に評価し、平均点数化した。
尚、シリコーンの析出量は、以下の方法で求めた。
(測定方法)
(1)アジア人毛髪を結って作った毛束1g(10cm)に対し、シャンプー8倍溶液1.6gで30秒間泡立てた。
(2)500mlの40℃温水で3回濯いだ。1回あたり、毛束を5回温水に浸漬と引き上げを繰り返すことで濯ぎを行った。
(3)毛束をドライヤーで乾燥した。
(4)試験管に処理した毛束を入れ、クロロホルム5mlを加え、30秒間振とうし、三角フラスコへ移した(3回繰り返す)。
(5)200ppmジニトロベンゼン内標(クロロホルム溶液)を5ml加えた。
(6)窒素ガスで乾固させた。
(7)クロロホルム1mlで三角フラスコを洗い、NMRチューブに入れて、1Hを測定した。
(8)測定結果より得られた内標とシリコーンのピーク強度(下記)から、シリコーン残留量をNMRより、定量した。
1H-NMRスペクトル
0.05-0.25ppm(Si-CH3)
