Description
本願発明は、多剤式（特に２剤式）ヘアリンス又はヘアトリートメントに関する。The present invention, multiple drug formulas (especially two-agent) about the f Alins or hair treat ment.
毛髪を化学的処理（ブリーチ処理等）すると、毛髪表面が損傷を受け、毛髪に滑らかさや艶が失われることがある。
そこで、傷んだ毛髪を修復し、毛髪に滑らかさや艶を付与するため、特定の変性シリコーンを配合したヘアリンスが提案されている（特許文献１）。When the hair is chemically treated (such as bleaching treatment), the hair surface may be damaged, and the hair may lose its smoothness and gloss.
Therefore, a hair rinse containing a specific modified silicone has been proposed in order to repair damaged hair and impart smoothness and gloss to the hair (Patent Document 1).
しかし、そのような従来のヘアリンスで毛髪処理した場合、毛髪は、滑らかさは付与されるもののザラザラしたものとなり、また厚ぼったい吸着感があり、艶も十分ではなかった。更には、ヘアリンスの塗布効果もあまり持続しない、という問題があった。 However, when the hair is treated with such a conventional hair rinse, the hair is smooth but rough and has a thick adsorption feeling, and the gloss is not sufficient. Furthermore, there is a problem that the effect of applying hair rinse does not last much.
上記事情に鑑み、本願発明は、毛髪（特に傷んだ毛髪）に、滑らかさ（特にツルツルした滑り）、コーティング感、及び十分な艶を付与し、更にヘアリンス等の塗布効果（又はコンディショニング効果）が持続する、ヘアリンス等を提供することを、目的とする。 In view of the above circumstances, the present invention provides hair (especially damaged hair) with smoothness (especially slippery slipping), a coating feeling, and sufficient gloss, and further has an application effect (or conditioning effect) such as hair rinse. The object is to provide a lasting hair rinse.
上記目的を達成するため、本願発明者が鋭意、検討した結果、下記本願発明を成すに到った。 In order to achieve the above object, the inventor of the present application diligently studied, and as a result, has reached the following present invention.

＜ヘアリンス処理毛の官能評価試験＞<Preparation of hair rinse>
According to the blending composition shown in Tables 1 and 2, each blending component is stirred and mixed uniformly to prepare agent A and agent B, respectively, and hair rinses (each example 7-9, reference examples 1-6, 10, 11, and Comparative examples 1-5) were prepared.
<Sensory evaluation test of hair rinse-treated hair>
毛束（長さ２５ｃｍ×幅６ｃｍ、３枚重ね人毛ミノ毛）をブリーチ処理し、更にシャンプー処理した後、水で濯いだ。この試験用毛束は、滑らかさや艶が失われていた。 A hair bundle (length 25 cm × width 6 cm, three-layer human hair mino hair) was bleached, further shampooed, and then rinsed with water. The test hair bundle had lost smoothness and gloss.
次いで、試験用毛束に、先ずヘアリンスＡ剤を塗布し、毛束全体によく馴染ませた。その後、その上から同容量のヘアリンスＢ剤を重ね塗りし、毛束全体によく馴染ませた。その後、この毛束を、水で濯ぎ、タオルドライし、乾燥させた。 Next, the hair rinse A agent was first applied to the test hair bundle, and was well adapted to the whole hair bundle. Thereafter, the same amount of Hair Rinse B agent was applied again from above, and the hair bundle was well adapted to the entire hair bundle. Thereafter, the hair bundle was rinsed with water, towel-dried and dried.
このようにしてヘアリンス処理された毛束の感触及び外観（艶）について、官能評価した。評価結果を、表１及び２に示す。 The sensory evaluation was performed on the feel and appearance (gloss) of the hair bundle treated in this manner. The evaluation results are shown in Tables 1 and 2.

The hair rinse-treated hair bundles were subjected to hair washing treatment (shampooing, rinsing, and drying) once a day from the next day. Then, by comparing the feel of the hair bundle immediately after the hair rinse treatment with the feel of the hair bundle after each hair washing treatment by a sensory test, it was confirmed how many times the hair rinse application effect disappeared. The test results are shown in Tables 1 and 2.

本願発明の作用・機序は、以下のように考えられる。
即ち、ブリーチ等の化学的処理により損傷した毛髪は、毛髪表面のキューティクルが捲（めく）れ上がっている（図２）。これが、損傷毛に滑らかさや艶を失わせている原因であると、一般に考えられている。The action and mechanism of the present invention can be considered as follows.
That is, hair damaged by chemical treatment such as bleaching has the cuticles on the hair surface curled up (FIG. 2). It is generally considered that this is the cause of the damaged hair losing its smoothness and gloss.
そこで、従来、ヘアリンスを用い毛髪表面にコーティング膜を形成（被覆）させることでキューティクルを毛髪表面に密着させ、その結果キューティクルが捲れ上がるのを防ぐ、という損傷毛の修復方法が採られている。 Therefore, conventionally, a method for repairing damaged hair has been adopted in which a cuticle is adhered to the hair surface by forming (coating) a coating film on the hair surface using a hair rinse, and as a result, the cuticle is prevented from rising.
しかし、従来のヘアリンスにより形成されるコーティング膜においては、十分な皮膜強度は無かった。そのため、キューティクルの捲れ上がりを十分に防ぐことはできなかった（図３）。 However, the coating film formed by the conventional hair rinse does not have sufficient film strength. Therefore, it was not possible to sufficiently prevent the cuticle from rolling up (FIG. 3).
一方、本願のヘアリンスにより形成されるコーティング膜は、Ａ剤の塗布層（就中、アミン基）とＢ剤の塗布層（就中、カルボキシル基）とが酸・塩基中和反応により強力にイオン結合している結果、非常に皮膜強度の高い強靭膜となっている。その結果、キューティクルの捲れ上がりが完全に防がれる（図１）と共に、コーティング膜の耐剥離性が向上するのでヘアリンスの塗布効果も持続することとなる。 On the other hand, the coating film formed by the hair rinse of the present application has a strong application of an agent A coating layer (especially an amine group) and an agent B coating layer (especially a carboxyl group) by an acid / base neutralization reaction. As a result of bonding, a tough film with extremely high film strength is obtained. As a result, curling up of the cuticle is completely prevented (FIG. 1), and the peeling resistance of the coating film is improved, so that the effect of applying the hair rinse is also maintained.
