Description

Hard surface detergent composition

The present invention relates to a detergent composition for a hard surface.

The living environment equipment around us has various hard surfaces made of ceramics, plastics, metals, etc., which are exposed to the environment where various stains are adhered in the living environment. Among them, the hard surface used as the floor is not only located at the lowermost part of the living environment equipment, but also the surface that people in daily life contact. Therefore, it is a property which has a large amount of stains which are likely to remain and accumulate, and are difficult to wash and remove.

For stains that are not easily absorbed on a hard surface such as a floor, they can be easily suctioned by a vacuum cleaner or simply wiped with a non-woven cloth. However, for residual stains containing oil and odor components remaining on the floor, it is necessary to wipe with a mop or wipe with a detergent. Domestic work such as these stains that are easily left on the floor and difficult to remove are a burden on the living. Moreover, the living person also expects to prevent the fungus from proliferating on the washed floor.

Further, it is said that there is a strong demand for improving the drying speed of a hard surface such as a floor to which a detergent composition is applied, in a country or a region where people live more than a living environment or have a poorly ventilated residential structure.

Japanese Laid-Open Patent Publication No. 2008-156607 discloses that the wettability of the floor is preferred by a combination of specific nonionic surfactants, and the dryness after wiping with water is also preferred, and the floor is not required to be wiped afterwards. Auxiliary with water wiping and so on. The described additives and the like exhibit excellent wetting even in the case of a cationic surfactant which significantly reduces the wettability. Sex. Further, Japanese Laid-Open Patent Publication No. 2011-241353 discloses a liquid detergent composition for flooring containing a specific nonionic surfactant, a cationic surfactant, a polyvalent carboxylic acid, and a fragrance. There is a description of a liquid detergent for a floor which suppresses the amount of the surfactant to be added to the water-insoluble flavoring compound to a small amount, and does not cause the remaining of the foam. JP-A-2008-266375 discloses a hard surface cleaning agent containing an amine oxide, a specific nonionic surfactant, a cationic surfactant, an organic acid, and a material which is less likely to cause damage to the material of the object to be washed.

The mass ratio (B)/(C) of the component (B) to the component (C) is 0.5 or more and 3.0 or less.

Moreover, the present invention relates to a cleaning solution obtained by diluting the above-described hard surface detergent composition of the present invention to 70 times or more and 200 times or less with water. The method of cleaning the hard surface of the surface.

Further, the present invention provides the use of the above composition as a detergent for a hard surface.

Furthermore, the present invention relates to a washing liquid obtained by diluting the above-mentioned hard surface detergent composition with water to 70 times or more, further 100 times or more, 200 times or less, and further 150 times or less as a hard surface. The use of the agent and the use of the above-mentioned composition in which the above-mentioned detergent is applied to a hard surface and which is not washed to dry the hard surface is used as a hard surface cleaning agent.

It is desired to have a high washing effect when the hard surface such as a floor is washed. However, it has been desired to improve the rationality by washing the stain containing the oil with the detergent composition and then improving the drying speed of the floor using the detergent composition and having a hard surface.

In addition, the growth of fungi remaining on the floor is a major problem for the living, and it is expected that a high sterilization effect is also imparted when the floor is washed.

The present inventors have found that the above prior art problems can be solved by formulating three kinds of surfactants at a specific concentration and a specific ratio, thereby completing the present invention.

The present invention provides a hard surface detergent composition which is excellent in detergency, sterilizing power, quick-drying property after washing, and rationality on a hard surface, particularly a hard surface such as a floor. Further, the present invention provides a hard surface detergent composition which is excellent in storage stability.

According to the present invention, there is provided a hard surface detergent composition which is excellent in detergency, degerming power, and quick-drying property and rationality after washing on a hard surface such as a floor. Further, according to the present invention, there is provided a hard surface detergent composition which is excellent in storage stability. Further, according to the present invention, there is provided a simple cleaning method which is excellent in quick-drying property after washing and excellent in handling, and which can complete a cleaned surface without washing.

The quick water-drying property of the water-repellent surface obtained from the hard surface detergent composition of the present invention is achieved by blending the component (A), the component (B) and the component (C) at a specific ratio. The mechanism is presumed as follows. Usually, a surfactant is contained in the droplet of the hard surface detergent composition remaining on the hard surface of the floor or the like. In this droplet, the concentration of the surfactant increases relatively as the water evaporates. As the concentration of the surfactant increases, the droplets containing the surfactant form a liquid crystal phase. In the liquid crystal phase, the convection of the liquid is poor and the evaporation of moisture is inhibited, so that the drying speed of the hard surface tends to decrease. In the present invention, since the component (A), the component (B), and the component (C) which are surfactants are mixed at a specific ratio, it is considered that even if the droplet is high in concentration due to evaporation of water, it does not form. The liquid crystal phase allows the evaporation of moisture to proceed rapidly. That is, it is considered that the present invention controls the phase state in the drying process by mixing a specific surfactant at a specific ratio, thereby achieving unprecedented quick-drying property.

In the present invention, by blending the component (A), the component (B), and the component (C) at a specific ratio, the improvement in the quick-drying property as described above and the improvement in the detergency and the sterilizing power can be achieved.
