Description

【0001】
【発明の属する技術分野】
本発明は、毛髪用組成物に関し、さらに詳しくは毛髪のコンディショニング効果、特に乾燥後の滑り性、しっとり感が良好な毛髪用組成物に関する。
【0002】
【従来の技術】
従来、毛髪の汚れを除去する目的で、アニオン界面活性剤を主成分とするシャンプーで洗髪するが、シャンプーで洗髪すると毛髪の汚れのみならず、毛髪表面を保護している油分も同時に除去されてしまい、毛髪の柔軟性が失われ、艶のないくし通りの悪い髪となり、毛髪の損傷、枝毛、切れ毛が発生し易くなる。そこで毛髪にコンディショニング効果(柔軟性、しっとり感、サラサラ感、滑り性)を付与する目的で、カチオン界面活性剤である第4級アンモニウム塩を主成分とする毛髪用組成物で処理するが、第4級アンモニウム塩を主成分とする毛髪用組成物を使用した場合、毛髪に対する柔軟性は優れているものの、乾燥後の滑り性、しっとり感が十分でない場合がある。そこで、乾燥後の滑り性を向上させるためにシリコーン油等を配合する方法が知られているが、シリコーン油等を配合する場合、配合量により系の安定性等に影響を及ぼすことがあり、配合量の制約を受けることもある。
【0003】
一方、カチオン界面活性剤を配合し、平滑性、柔軟性を付与する目的で、特許文献1及び特許文献2には、高級アルコールにエチレンオキサイドを付加したエーテル基を有するエーテル型第4級アンモニウム塩が提案されている。また、特許文献3及び特許文献4には、アルキル基に水酸基を有する2−ヒドロキシアルキル型第4級アンモニウム塩を用いた、柔軟性、平滑性に優れたヘアリンス剤が提案されているが、これらの提案では、十分満足のいくしっとり感、滑り性は得られていない。
【0004】
本発明に使用される上記一般式(1)のヒドロキシエーテル型カチオン界面活性剤は公知物質であり、特許文献5にはヒドロキシエーテル型カチオン界面活性剤と特定のアルコールを用い、安定な液体洗浄剤組成物が提案され、また特許文献6にはアミノ酸高級アルキルエステル塩及びそのN−低級アルキル置換体の中から選ばれた少なくとも1種とヒドロキシエーテル型カチオン界面活性剤を用い、アミノ酸高級アルキルエステル塩及びそのN−低級アルキル置換体の加水分解を抑制するカチオン界面活性剤組成物が提案されているが毛髪用組成物に関する記載ではない。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a hair composition, and more particularly to a hair composition having a good conditioning effect on hair, particularly good slipperiness after drying and a moist feeling.
[0002]
[Prior art]
Conventionally, for the purpose of removing hair stains, the hair is washed with a shampoo containing an anionic surfactant as a main component, but when the hair is washed with a shampoo, not only the hair stains but also the oil protecting the hair surface is removed at the same time. As a result, the flexibility of the hair is lost, and the hair becomes dull and poorly combed, and the hair is likely to be damaged, split and cut. Therefore, for the purpose of imparting conditioning effects (flexibility, moist feeling, smooth feeling, slipperiness) to the hair, the hair is treated with a hair composition mainly containing a quaternary ammonium salt as a cationic surfactant. When a hair composition containing a quaternary ammonium salt as a main component is used, the hair has excellent flexibility but may not have sufficient lubricity and dryness after drying. Therefore, a method of blending silicone oil or the like in order to improve the slipperiness after drying is known, but when blending silicone oil or the like, the blending amount may affect the stability of the system, In some cases, the amount is limited.
[0003]
On the other hand, for the purpose of adding a cationic surfactant to impart smoothness and flexibility, Patent Documents 1 and 2 disclose ether type quaternary ammonium salts having an ether group obtained by adding ethylene oxide to a higher alcohol. Has been proposed. Patent Literature 3 and Patent Literature 4 propose a hair rinse agent having excellent flexibility and smoothness using a 2-hydroxyalkyl type quaternary ammonium salt having a hydroxyl group in an alkyl group. Does not provide a sufficiently satisfactory moist feeling and slipperiness.
[0004]
The hydroxy ether type cationic surfactant of the above general formula (1) used in the present invention is a known substance, and Patent Document 5 discloses a stable liquid detergent using a hydroxy ether type cationic surfactant and a specific alcohol. Patent Document 6 discloses an amino acid higher alkyl ester salt using at least one selected from amino acid higher alkyl ester salts and N-lower alkyl substituted products thereof and a hydroxyether type cationic surfactant. And a cationic surfactant composition for suppressing the hydrolysis of the N-lower alkyl-substituted product have been proposed, but do not disclose a hair composition.

After drying, the hair was fixed on a slide, and the dynamic friction coefficient (MIU) was measured with a friction tester (KES-SE manufactured by Kato Tech) under the following conditions.
Measurement weight: 50g
Number of measurements: The reduction rate from the blank measured simultaneously 10 times was calculated as follows.
Reduction rate = (M B -M S) / M B × 100
M B : MIU value of blank M S : Criteria for evaluation of MIU value of cationic surfactant were set as follows.
