Description
本発明は、ガラス、金属、プラスチック等の各種硬質材料の表面を洗浄するための硬質表面用洗浄剤組成物に関する。 The present invention relates to a hard surface cleaning agent composition for cleaning the surface of various hard materials such as glass, metal and plastic.
我々の日常生活は、ガラス、金属、プラスチック等を材料とした各種硬質表面のものに囲まれており、これら硬質表面には生活の中、様々な汚れが付着する。例として、車窓などのガラスに付着する水垢等の無機汚れがある。これら無機汚れを落とすためには酸性洗浄剤を用いることが有効ではあるが、酸性に強くない金属などを損傷するおそれがある。
酸性洗浄剤以外で水垢などの無機汚れを落とすものとしては、カチオン性界面活性剤が配合された洗浄剤が挙げられる。硬質表面用洗浄剤組成物として、例えば、特許文献1にはカチオン性界面活性剤と両性界面活性剤を含む組成物が開示され、特許文献2にはカチオン性界面活性剤と非イオン性界面活性剤を含む組成物が開示されている。
しかしながら、これらの組成物では洗浄時に泡立ってしまい、すすぎに時間のかかることがある。
Our daily life is surrounded by various hard surfaces made of glass, metal, plastic, etc., and various stains adhere to these hard surfaces in our daily lives. An example is inorganic stains such as water stains that adhere to glass such as car windows. Although it is effective to use an acidic cleaning agent to remove these inorganic stains, there is a risk of damaging metals that are not resistant to acidity.
Examples of those that remove inorganic stains such as scale other than acidic cleaning agents include cleaning agents containing a cationic surfactant. As a hard surface cleaning composition, for example, Patent Document 1 discloses a composition containing a cationic surfactant and an amphoteric surfactant, and Patent Document 2 discloses a cationic surfactant and a nonionic surfactant. Compositions comprising the agent are disclosed.
However, these compositions may foam during washing and may take a long time to rinse.
また、硬質表面としてはキッチンのガスコンロの金属も挙げられる。このような金属表面には、食品や揚げ物用の油などに由来する汚れが多く付着するので、その洗浄剤として例えば特許文献3に開示された、カチオン性界面活性剤と非イオン性界面活性剤を含む組成物が使用されることがある。
しかしながら、本組成物では洗浄時に泡立ってしまい、拭き取りに時間のかかることがある。
Further, as a hard surface, metal of a gas stove in a kitchen can be mentioned. Since many stains derived from oils for foods and fried foods adhere to such metal surfaces, cationic surfactants and nonionic surfactants disclosed in, for example, Patent Document 3 as cleaning agents thereof. Compositions containing may be used.
However, with this composition, foaming may occur during washing, and it may take time to wipe off.
更に、硬質表面としては床面のような人が接する機会の多い樹脂素材も挙げられる。床面では多くの汚れが残留して蓄積し、洗浄しにくい性質を有する汚れとなっている。
この汚れを効果的に洗浄するためには、汚れに対する洗浄剤の浸透性を高めることが考えられる。例えば特許文献4には、オキシエチレン基の長い非イオン性界面活性剤とカチオン性界面活性剤を含む組成物が示されている。
しかしながら、本組成物においても洗浄時に泡が立ち、すすぎに時間のかかることがある。
Further, as a hard surface, a resin material such as a floor surface, which is often in contact with a person, can be mentioned. A lot of dirt remains and accumulates on the floor surface, making it difficult to clean.
In order to effectively clean this stain, it is conceivable to increase the permeability of the cleaning agent to the stain. For example, Patent Document 4 discloses a composition containing a nonionic surfactant having a long oxyethylene group and a cationic surfactant.
However, even in this composition, foaming may occur during washing and it may take time to rinse.
一方で、泡立ちを抑制する洗浄剤として、例えば特許文献5には、アルカリ性液中において使用する洗浄剤で、オキシエチレン基とオキシプロピレン基を有する非イオン性界面活性剤とカチオン性界面活性剤を含む組成物が示されている。本組成物では、特定の非イオン性界面活性剤で泡立ちを抑制し、更に特定のカチオン性界面活性剤を用いることで、硬質表面へのカチオン性界面活性剤の付着を抑制し、すすぎ性を向上させている。
しかしながら、本組成物においても1回水洗では、すすぎが不十分となることがある。
このように、水垢や油汚れ、床の堆積汚れなどの硬質表面の汚れに対して浸透性を高めることで更に洗浄力を向上させ、且つ泡立ち抑制してすすぎやすい硬質表面用洗浄剤組成物が求められている。
On the other hand, as a cleaning agent that suppresses foaming, for example, Patent Document 5 describes a nonionic surfactant and a cationic surfactant having an oxyethylene group and an oxypropylene group as cleaning agents used in an alkaline liquid. The composition comprising is shown. In this composition, foaming is suppressed with a specific nonionic surfactant, and further, by using a specific cationic surfactant, the adhesion of the cationic surfactant to the hard surface is suppressed and the rinse property is improved. It is improving.
However, even in this composition, rinsing may be insufficient by one washing with water.
In this way, a cleaning agent composition for hard surfaces that further improves the detergency by increasing the permeability to stains on the hard surface such as water stains, oil stains, and accumulated stains on the floor, and suppresses foaming to facilitate rinsing. It has been demanded.
そこで、本発明が解決しようとする課題は、各種硬質材料の表面の洗浄時に用いられる洗浄剤組成物であって、硬質表面の汚れに対する浸透性を付与することで更に洗浄力を向上させつつ、泡立ち抑制することですすぎ性を向上させた硬質表面用洗浄剤組成物を提供することである。 Therefore, the problem to be solved by the present invention is a cleaning agent composition used when cleaning the surface of various hard materials, while further improving the cleaning power by imparting permeability to stains on the hard surface. It is to provide a cleaning agent composition for a hard surface having improved rinseability by suppressing foaming.
上記課題を解決するため、本発明者が鋭意検討した結果、カチオン界面活性剤と特定の2種類の非イオン界面活性剤とを組み合わせて用いることによって、硬質表面の汚れに対する浸透性を付与することで更に洗浄力を向上させつつ、泡立ちを抑制することですすぎ性を向上させた硬質表面用洗浄剤組成物が得られることを見出し、本発明の完成に至ったものである。 As a result of diligent studies by the present inventor in order to solve the above problems, it is possible to impart permeability to stains on a hard surface by using a cationic surfactant and two specific types of nonionic surfactants in combination. It has been found that a cleaning agent composition for a hard surface having improved rinsability can be obtained by suppressing foaming while further improving the detergency, and the present invention has been completed.
