Description

  The present invention relates to a hard surface cleaning composition.

  The living environment equipment that surrounds us has various hard surfaces made of tile, plastic, metal, etc., and these hard surfaces are exposed to an environment where various kinds of dirt adhere in daily life. In particular, the hard surface used as the floor is located at the bottom of the living environment equipment and is also the surface that people come into contact with on a daily basis. For this reason, a large amount of dirt remains and accumulates, and further, it is difficult to remove by washing.

  For easily removed dirt that is not adsorbed on a hard surface such as a floor surface, it is possible to simply clean it with a vacuum cleaner or a wiper using a nonwoven fabric. However, the remaining dirt containing oil and the odor component remaining on the floor must be wiped with a mop or wiped with a cleaning agent. Household behavior against dirt that remains on the floor surface and is difficult to remove is a heavy burden on consumers. It is also desired by consumers to be able to prevent the growth of fungi on the floor after washing.

  In countries and regions where the living environment is often barefoot or where the housing structure is poorly ventilated, it is desirable to improve the drying speed of hard surfaces such as floors to which a cleaning composition is applied. It is said that there is a high demand.

  Patent Document 1 includes a floor water wiping aid that has good wettability to the floor surface due to a combination of specific nonionic surfactants, and also has good drying properties after water wiping, and does not require post-wiping. It is disclosed. An auxiliary agent that exhibits excellent wettability is described even when it contains a cationic surfactant that significantly reduces wettability. Patent Document 2 discloses a liquid detergent composition for floors containing a specific nonionic surfactant, a cationic surfactant, a polyvalent carboxylic acid, and a fragrance. There is a description of a liquid cleaning agent for floors that does not cause foam residue and the like, in which the blending amount of the surfactant with respect to the water-insoluble fragrance compound is kept small. Patent Document 3 describes a hard surface cleaning agent that contains an amine oxide, a specific nonionic surfactant, a cationic surfactant, and an organic acid and hardly damages the material of an object to be cleaned.

  When a hard surface such as a floor surface is cleaned, a high cleaning effect is a desired function. However, it has been desired to improve the finishing performance by cleaning the soil containing oil with the cleaning composition and then increasing the drying speed of the floor surface, which is a hard surface to which the soil is applied.

The mass ratio (B) / (A) of the component (B) to the component (A) is 0.5 or more and 1.5 or less,
The mass ratio (C) / (A) of the component (C) to the component (A) is 0.5 or more and 1.5 or less,
The mass ratio (B) / (C) of the component (B) to the component (C) is 0.5 or more and 3.0 or less.
The present invention relates to a hard surface cleaning composition.

  Moreover, this invention relates to the cleaning method of the hard surface which applies the cleaning liquid which diluted the cleaning composition for hard surfaces of the said invention to 70 times or more and 200 times or less with water to a hard surface.

Furthermore, this invention provides the use as a cleaning agent for hard surfaces of said composition.
In addition, the present invention is a use as a hard surface cleaning agent of a cleaning liquid in which the hard surface cleaning composition is diluted 70 times or more, further 100 times or more, and 200 times or less, and further 150 times or less with water, Furthermore, the present invention relates to the use of the composition as a hard surface cleaning agent, wherein the hard surface is dried without rinsing after the cleaning agent is applied to the hard surface.

  ADVANTAGE OF THE INVENTION According to this invention, the hard surface cleaning composition which is excellent in the detergency with respect to hard surfaces, such as a floor surface, disinfection power, and quick-drying after finishing and finishing property is provided. Moreover, according to this invention, the hard surface cleaning composition with favorable storage stability is provided. Furthermore, according to the present invention, since it is excellent in quick-drying and finishing after washing, a simple method for washing a hard surface is provided that can complete washing without rinsing.

  The quick-drying property of the residual water droplets on the cleaning surface obtained by the hard surface cleaning composition of the present invention is achieved by the fact that the (A) component, the (B) component, and the (C) component are formulated in a specific ratio. It is what is done. The mechanism is presumed as follows. Usually, the surfactant is contained in the liquid droplets of the hard surface cleaning composition remaining on the hard surface such as a floor. In the droplet, the concentration of the surfactant is relatively increased with the evaporation of moisture. As the surfactant concentration increases, the droplets containing the surfactant form a liquid crystal phase. Since the liquid crystal phase has poor liquid convection and inhibits evaporation of moisture, it tends to reduce the drying rate. In the present invention, since the components (A), (B), and (C), which are surfactants, are mixed at a specific ratio, the liquid crystal is used even when the concentration becomes high due to evaporation of moisture in the droplets. No phase is formed, and it is considered that the evaporation of moisture proceeds rapidly. That is, in the present invention, it is considered that unprecedented quick drying is realized by mixing a specific surfactant at a specific ratio and controlling the phase state in the drying process.

  In the present invention, by prescribing the components (A), (B), and (C) at specific ratios, in addition to the improvement in quick-drying as described above, the improvement in cleaning power and sterilization power is realized. it can.
