【００２７】
【実施例】
以下に、本発明を実施例により具体的に説明するが、本発明はこれらに限定されるものではない。
実施例に先立ち、ブリーチ毛髪中のカルシウムイオン（Ｃａ^２＋）の定量および界面活性剤のキレート能の測定を次の方法で行った。
【００２８】
（１）ブリーチ毛髪中のカルシウムイオン（Ｃａ^２＋）の定量
次の方法で、試料数を４とし、無処理の毛髪のイオン交換水洗浄の場合を１００としてカルシウムイオン（Ｃａ^２＋）の定量を行った。その結果を図１に示す。
【００２９】
（処理方法）
毛髪を０．１Ｎ塩酸で３０分処理後（ａとする）、イオン交換水で洗浄して付着イオンを除去した。次いで、２０ｍＭ酢酸ナトリウム緩衝液でｐＨ６とし、Ｃａ^２＋５００ｐｐｍで処理し、９０分，４０℃でインキュベート後、イオン交換水で洗浄した（ｂとする）。次いで、５００ｐｐｍＣａ^２＋で処理したブリーチ毛を、ヤシ油脂肪酸アシルグルタミン酸カリウム、Ｎ−アシルエチレンジアミン三酢酸ナトリウム、ヒドロキシエーテルカルボン酸塩、各１％水溶液、ｐＨ５．３で９０分，４０℃でインキュベート後、イオン交換水で洗浄した（ヤシ油脂肪酸アシルグルタミン酸カリウム処理をｃ−１、Ｎ−アシルエチレンジアミン三酢酸ナトリウム処理をｃ−２、ヒドロキシエーテルカルボン酸塩をｃ−３とする）。
【００３０】
（結果）
図１からわかるように、ブリーチ毛髪は硬水処理でＣａ^２＋量が増加した。また、硬水処理したブリーチ毛髪にヤシ油脂肪酸アシルグルタミン酸カリウム処理することで、Ｃａ^２＋量が減少し、その減少量はＮ−アシルエチレンジアミン三酢酸ナトリウムと同程度であった。なお測定値は、ａ＝３６，ｂ＝１２２，ｃ−１＝５８，ｃ−２＝５６，ｃ−３＝６３であった。
【００３１】
（２）界面活性剤のキレート能の測定
種々の界面活性剤の５％水溶液１０ｍｌを１％のＣａＣｌ_２で滴定した。その結果を図２に示す。図中、ＬＥＳはポリオキシエチレンラウリルエーテル硫酸ナトリウム、ＡＭＴはヤシ油脂肪酸メチルタウリンナトリウム、アミライトはＮ−ヤシ油脂肪酸アシルグリシンナトリウム、サルコシネートＣＴ−３０はヤシ油脂肪酸サルコシントリエタノールアミン、ＲＭ−２はラウリルグリコール酢酸ナトリウム、アミソフトＣＫ−２２はヤシ油脂肪酸アシルグルタミン酸カリウム、ＬＥＤ−３ＡＮａはＮ−アシルエチレンジアミン三酢酸ナトリウムをそれぞれ示す。なお、ＬＥＳ、ＡＭＴは、ラウリン酸カリウムを混合した。
【００３２】
（結果）
図２からわかるように、ＬＥＤ−３ＡＮａ（Ｎ−アシルエチレンジアミン三酢酸ナトリウム）が最も高いキレート能を有し、次いで、アミソフトＣＫ−２２（ヤシ油脂肪酸アシルグルタミン酸カリウム）、ＲＭ−２（ラウリルグリコール酢酸ナトリウム）の順にキレート能が低下している。図１と図２を併せて考察すると、キレート能の高さとＣａ^２＋量の減少量とは必ずしも相関しているわけではないことが分かり、特にアミソフトＣＫ−２２（ヤシ油脂肪酸アシルグルタミン酸カリウム）によるＣａ^２＋量の減少量がキレート能から考えられる以上に顕著なことが判明した。

Problems to be solved by the prior art and the invention
At present, the most commonly used conditioners in shampoos are cationic polymers, silicones or silicone derivatives, and shampoos containing these conditioners have a greater effect on shampoo after hair washing or shampooing than shampoos without a conditioner. The post-dried hair can be imparted with considerably increased entanglement, softness and smoothness.
[0003]
Furthermore, at the present time, coloring and perming are often performed, and the damage to the hair is becoming severe, but with this, the number of people who are worried that the hair is stiff, stiff, and finger passing is worse are doing. As one of the causes, it has been pointed out that calcium ions are more likely to be adsorbed to the perm-treated hair than to the normal hair, and as a result, it has been reported that the hair becomes harder (see Non-Patent Document 1).
[0004]
The present inventors have paid attention to this point, and as a result of intensive studies to develop a cleaning composition optimal for hair damaged by a perm treatment or a bleach treatment (including a color treatment), as a result, a specific cleaning agent having a metal ion removing effect has been obtained. If the surfactant, oil and cationic polymer are combined and combined, the hair is excellent in smoothness, flexibility and conditioning effect from rinsing to after rinsing, and also has excellent usability and product stability. It has been found that an agent composition can be obtained, and the present invention has been completed.

【Example】
Hereinafter, the present invention will be described specifically with reference to Examples, but the present invention is not limited thereto.
Prior to the examples, quantification of calcium ions (Ca ²⁺ ) in bleached hair and measurement of the chelating ability of the surfactant were performed by the following methods.
[0028]
(1) Quantification of Calcium Ion (Ca ²⁺ ) in Bleach Hair In the following method, the number of samples was set to 4, and the amount of calcium ion (Ca ²⁺ ) was determined to be 100 in the case of untreated hair washing with ion-exchanged water. Was. The result is shown in FIG.
[0029]
(Processing method)
After treating the hair with 0.1 N hydrochloric acid for 30 minutes (referred to as “a”), the hair was washed with ion-exchanged water to remove attached ions. Next, the mixture was adjusted to pH 6 with a 20 mM sodium acetate buffer, treated with 500 ppm of Ca ²⁺ , incubated at 40 ° C. for 90 minutes, and washed with ion-exchanged water (b). Next, the bleach hair treated with 500 ppm Ca ²⁺ was incubated at 40 ° C. for 90 minutes at potassium coconut fatty acid potassium acylglutamate, sodium N-acylethylenediaminetriacetate, hydroxyether carboxylate, 1% aqueous solution, pH 5.3, and pH 5.3, Washing with ion-exchanged water (c-1 for coconut oil fatty acid acylglutamate treatment, c-2 for sodium N-acylethylenediaminetriacetate treatment, and c-3 for hydroxyethercarboxylate).
[0030]
(result)
As can be seen from FIG. 1, the amount of Ca ^{2+ of} bleached hair was increased by hard water treatment. In addition, the amount of Ca ²⁺ was reduced by treating the hardened bleach hair with coconut oil fatty acid potassium acylglutamate, and the amount of reduction was about the same as that of sodium N-acylethylenediaminetriacetate. The measured values were a = 36, b = 122, c-1 = 58, c-2 = 56, and c-3 = 63.
[0031]
(2) Measurement of chelating ability of surfactants 10 ml of 5% aqueous solutions of various surfactants were titrated with 1% CaCl ₂ . The result is shown in FIG. In the figure, LES is sodium polyoxyethylene lauryl ether sulfate, AMT is coco oil fatty acid sodium methyltaurine sodium, amylite is N-coco oil fatty acid acyl glycine sodium, sarcosinate CT-30 is coco oil fatty acid sarcosine triethanolamine, and RM-2 is RM-2. Sodium lauryl glycol acetate, Amisoft CK-22 indicate coconut oil fatty acid potassium acylglutamate, and LED-3ANa indicates sodium N-acylethylenediaminetriacetate. In addition, LES and AMT mixed potassium laurate.
[0032]
(result)
As can be seen from FIG. 2, LED-3ANa (sodium N-acylethylenediaminetriacetate) has the highest chelating ability, followed by Amisoft CK-22 (potassium coconut oil acyl glutamate) and RM-2 (lauryl glycol acetate). Chelating ability decreases in the order of sodium). When FIG. 1 and FIG. 2 are considered together, it is found that the high chelating ability and the decrease in the amount of Ca ²⁺ are not always correlated, and in particular, by the use of Amisoft CK-22 (potassium coconut fatty acid acylglutamate). It was found that the decrease in the amount of Ca ²⁺ was more remarkable than expected from the chelating ability.
