Detailed Description of the Invention

It is a desirable function to have a high cleaning effect when cleaning hard surfaces such as floor surfaces. 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.

In addition, since the scent of odor is desired after washing, the amount of flavor added may be increased. However, in order to increase the amount of the fragrance stably, the blending amount of the dispersant and solubilizer for the fragrance had to be increased. However, when these components are blended, there is a concern about a decrease in quick-drying and finish of hard surfaces. Therefore, it has been desired to improve the finish by improving the quick drying property of the floor surface which is a hard surface.

The present inventor has found that the problems of the prior art can be solved by blending specific three kinds of surfactants with a specific amount of perfume in a limited concentration and ratio, and has completed the present invention. .

The present invention provides a hard surface cleaning composition that is excellent in detergency for hard surfaces, particularly hard surfaces such as floor surfaces, and quick drying and finishing properties after cleaning. Furthermore, the present invention provides a hard surface cleaning composition having good blending stability.

According to the present invention, there is provided a hard surface cleaning composition that is excellent in detergency on a hard surface such as a floor surface, as well as quick-drying and finishing properties after cleaning. Moreover, according to this invention, the hard surface cleaning composition with favorable mixing | blending stability is provided. Furthermore, according to the present invention, since a relatively high concentration of a fragrance can be stably blended even with a low concentration of a surfactant, a hard surface cleaning composition excellent in a fragrance effect on the surface to be cleaned and its durability is provided. Is done. 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 formulating the (A) component, the (B) component, and the (C) component at specific ratios, in addition to the improvement in quick drying as described above, the improvement in cleaning power and a relatively high concentration Stable blending of fragrances can also be realized.
