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 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 dirt adheres to these hard surfaces in our lives. As an example, there is inorganic dirt such as water scale adhering to glass such as car windows. In order to remove these inorganic stains, it is effective to use an acidic cleaning agent, but there is a risk of damaging a metal that is not highly acidic.
As an agent that removes inorganic stains such as scales other than the acidic detergent, a detergent containing a cationic surfactant may be mentioned. As the 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. A composition comprising an agent is disclosed.
However, these compositions may foam during cleaning and may take 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。
Moreover, the metal of the gas stove of a kitchen is also mentioned as a hard surface. Since a lot of dirt derived from oil for foods and fried foods adheres to such a metal surface, a cationic surfactant and a nonionic surfactant disclosed in Patent Document 3, for example, as cleaning agents thereof May be used.
However, with this composition, foaming may occur during cleaning, and wiping may take time.

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, examples of the hard surface include a resin material such as a floor surface that is frequently contacted by people. On the floor surface, a lot of dirt remains and accumulates, and the dirt has a property that is difficult to clean.
In order to effectively clean the dirt, it is conceivable to increase the permeability of the cleaning agent to the dirt. For example, Patent Document 4 discloses a composition containing a nonionic surfactant having a long oxyethylene group and a cationic surfactant.
However, even in the present composition, bubbles may form 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 discloses a cleaning agent used in an alkaline liquid, which includes a nonionic surfactant having an oxyethylene group and an oxypropylene group, and a cationic surfactant. A composition comprising is shown. In this composition, the foaming is suppressed with a specific nonionic surfactant, and by using a specific cationic surfactant, the adhesion of the cationic surfactant to the hard surface is suppressed, and the rinsing property is improved. It is improving.
However, even in the present composition, rinsing may be insufficient when washed once with water.
Thus, there is provided a hard surface cleaning composition that can be easily rinsed by further improving the detergency by increasing the permeability to hard surface dirt such as water scale, oil dirt, and floor accumulated dirt, and suppressing foaming. It has been demanded.

When the carbon number of R 5 is too small or too large, the permeability may be poor.
a is an average addition mole number of an oxyethylene group, a = 2-9, and especially a = 2-5 are preferable. When “a” is too small, the compatibility of the component (B) with water decreases, so that insoluble matter aggregates on the hard surface, resulting in residual after rinsing and poor cleaning properties. On the other hand, when a is too large, the hydrophilicity of the component (B) becomes strong, so that the permeability and the low foaming property may be inferior.

a / b is the ratio of the average added mole number a of oxyethylene groups to the average added mole number b of oxypropylene groups, and is 0.5 to 3.0, preferably 1.0 to 2.8. Particularly preferred is 1.2 to 2.5. When a / b is too small, the component (B) is less compatible with water, so that the insoluble matter agglomerates on the hard surface, resulting in a residue after rinsing and poor cleaning properties. When a / b is too large, the hydrophilicity of the component (B) becomes strong, which may result in poor permeability and low foamability.
In addition, 1 type, or 2 or more types of the compound shown by Formula (2) can be used as a component (B).

本発明の洗浄剤組成物における(B)成分の含有量は、40〜75質量%であり、特に45〜65質量%が好ましい。(B)成分の含有量が少なすぎる場合、浸透性や低泡性に劣ることがあり、(B)成分の含有量が多すぎる場合、水に対する飽和溶解度を超えるために硬質表面に不溶分が凝集し、すすぎ後の残存を生じて洗浄性に劣ることがある。   Content of (B) component in the cleaning composition of this invention is 40-75 mass%, and 45-65 mass% is especially preferable. When the content of the component (B) is too small, the permeability and the low foaming property may be inferior.

Aggregates and may remain after rinsing, resulting in poor cleanability.

〔(C)成分〕

cはオキシエチレン基の平均付加モル数であり、c=1〜5であり、特にc=1〜3が好ましい。cが大きすぎる場合、(C)成分の親水性が強くなることにより、浸透性や低泡性に劣ることがある。

When the carbon number of R 6 is too small, it may be particularly inferior in oil stain detergency and in permeability, and when the carbon number of R 6 is too large, component (C) is less compatible with water. Therefore, insoluble matter aggregates on the hard surface, resulting in a residue after rinsing and poor cleaning properties.
c is an average addition mole number of an oxyethylene group, c = 1 to 5, and c = 1 to 3 is particularly preferable. When c is too large, the hydrophilicity of the component (C) may become strong, resulting in inferior permeability and low foamability.
In addition, 1 type, or 2 or more types of the compound shown by Formula (3) can be used as a component (C).

本発明の洗浄剤組成物における(C)成分の含有量は、3〜15質量%であり、好ましくは5〜15質量%であり、特に好ましくは10〜15質量%である。(C)成分の含有量が少なすぎる場合、特に油汚れの洗浄性に劣ること、また浸透性に劣ることがあり、(C)成分の含有量が多すぎる場合、水に対する飽和溶解度を超えるために硬質表面に不溶分が凝集し、すすぎ後の残存を生じて洗浄性に劣ることがある。   Content of (C) component in the cleaning composition of this invention is 3-15 mass%, Preferably it is 5-15 mass%, Most preferably, it is 10-15 mass%. When the content of the component (C) is too small, the oil stains are particularly poorly washed, and the permeability may be poor.
