【発明の属する技術分野】
本発明は食器用洗浄剤組成物、さらに詳細には食器の表面上に残留した水の硬度成分由来の固着汚れを効果的に除去することができ、硬質表面本来の美観を蘇らせることのできる食器用液体洗浄剤組成物に関する。
【０００２】
【従来の技術および発明が解決しようとする課題】
人体に対する安全性意識が益々高まってきている今日、台所用洗浄剤は人体に触れる機会の多い洗浄剤であるので、洗浄力を高めるとともに皮膚への作用を温和にする検討がなされている。良く知られている技術として、陰イオン性界面活性剤であるポリオキシエチレンアルキルエーテル硫酸塩とアルキルジメチルアミンオキシドを併用する方法がある。この技術では油性汚れ洗浄力を高めつつ、皮膚に対する温和性を向上することができる。これは、イオン対形成による相乗効果によるものである。すなわち、アルキルジメチルアミンオキシドが溶液中で陽イオン性構造と非イオン性構造の平衡状態にあり、陽イオン性構造のアミンオキシドが陰イオン性界面活性剤とイオン対を形成するため、静電的結合力の働きで界面活性剤が表面や界面に密に並び、泡立ちや油性汚れ洗浄力が増加する。
【０００３】
しかし、この技術はあくまでも界面活性剤の界面活性能を利用したものであり、水の硬度成分に由来するカルシウム塩やマグネシウム塩等の固着汚れに対しては全く効果がなかった。洗浄水やすすぎ水に水道水が使用されているため、硬度成分由来の固着汚れが食器表面に必ず存在する。この種の汚れを効果的に除去でき、かつ皮膚に対して温和な洗浄剤組成物が望まれていた。

Nowadays, the safety awareness for the human body is increasing, and since kitchen detergents are detergents with many opportunities to touch the human body, studies have been made to increase the cleaning power and mildly affect the skin. As a well-known technique, there is a method in which polyoxyethylene alkyl ether sulfate, which is an anionic surfactant, and alkyldimethylamine oxide are used in combination. With this technique, it is possible to improve the mildness to the skin while enhancing the oily soil cleaning power. This is due to a synergistic effect due to ion pair formation. That is, since the alkyldimethylamine oxide is in equilibrium between the cationic structure and the nonionic structure in the solution, and the amine oxide of the cationic structure forms an ion pair with the anionic surfactant, Due to the binding force, the surfactants are densely arranged on the surface and interface, and foaming and oily dirt cleaning power are increased.
[0003]
However, this technique only uses the surface active ability of the surfactant, and has no effect on fixing stains such as calcium salts and magnesium salts derived from the hardness component of water. Since tap water is used for washing water and rinsing water, fixed dirt derived from hardness components always exists on the tableware surface. There has been a demand for a cleaning composition that can effectively remove this type of soiling and is gentle to the skin.
