ADVANTAGE OF THE INVENTION According to this invention, the liquid cleaning composition for hard surfaces which is excellent in the detergency of the oil stain containing the solid fat adhering to the hard surface, and shows favorable foam discharge property, and the washing | cleaning of the hard surface using the same A method can be provided.
The liquid detergent composition for a hard surface of the present invention can be applied to an oil stain containing solid fat adhering to an article having a hard surface such as plastic without using a flexible material such as a sponge, that is, mechanical force. It is possible to clean without using a foam, and when used in a sprayer, a good foam discharge property such as a large foaming amount can be exhibited.

<Liquid detergent composition for hard surface>
The liquid detergent composition for hard surface of the present invention defines the content of an anionic surfactant having a hydrocarbon group having 8 to 21 carbon atoms and a sulfate ester group or a sulfonic acid group as the component (b). Thus, the interaction between the component (a) having a dialkyl group having high hydrophobicity and a sulfate group having high hydrophilicity and the component (c) which is amine oxide can be strengthened. As a result, the surfactant contained in the hard surface liquid detergent composition of the present invention can easily penetrate into the oil stain containing solid fat, and the solid fat in the oil stain component can be easily peeled off. It is presumed that the effect of improving the cleaning power was obtained.
And when using the liquid detergent composition for hard surfaces of the present invention in a method of directly contacting the hard surface, the concentration of the surfactant applied to the hard surface is determined by using a sponge containing water. It becomes higher than the case where it contacts. For this reason, the effect of the surfactant of the present invention is more prominent.
From these, by using the liquid detergent composition for hard surface of the present invention, oil stains containing solid fat adhering to a hard surface such as plastic are not rubbed with a flexible material such as sponge. In other words, excellent cleaning power can be obtained even by a cleaning method in which no mechanical force is applied.

<Cleaning method of hard surface>
The hard surface cleaning method of the present invention is a hard surface cleaning method in which the hard surface liquid cleaning composition of the present invention is brought into contact with a hard surface.
That is, the hard surface cleaning method of the present invention uses the hard surface liquid cleaning composition of the present invention. The preferable aspect of this composition is the same as the liquid detergent composition for hard surfaces described above.
The method for cleaning a hard surface according to the present invention comprises contacting the liquid detergent composition for hard surface according to the present invention with a hard surface to which oil stains are attached and further to a hard surface to which oil stains containing solid fat are attached. It can carry out suitably as a washing method. These methods are hard surface cleaning methods in which the hard surface liquid detergent composition of the present invention is brought into contact with oil stains adhering to the hard surface.
In one aspect, the present invention provides a method for cleaning a hard surface, wherein the liquid detergent composition for hard surface for oil removal according to the present invention is brought into contact with a hard surface to which oil stains adhere.
The oil stain containing solid fat is a stain containing oil and fat, and the oil and fat exhibits a solid at normal temperature (for example, 20 ° C.). The oil stain containing solid fat is typically an oil stain containing solid fat, and an oil stain containing solid fat and liquid oil. The form of the oil stain containing solid fat when contacting the liquid detergent composition for hard surface may be a state where solid fat and liquid oil are mixed.

In the hard surface cleaning method of the present invention, the hard surface liquid detergent composition is brought into contact with the hard surface.

The mass of a 30 mm (horizontal) × 80 mm (vertical) × 1 mm (thickness) polypropylene test piece was measured with a 4-digit balance (x). A model soil was applied to both sides of the polypropylene test piece uniformly to a height of 50 mm from the lower end so as to be 0.02 to 0.03 g in total on both sides, to obtain a soil piece. The mass of the dirty piece was measured with a 4-digit balance (y).

  50 g of the hard surface liquid detergent composition was placed in a 50 mL container (inner diameter 35 mm × height 68 mm columnar shape), and then one piece of dirt was leaned into the container and brought into contact with the composition. At this time, the part of the dirt piece to which the dirt was attached was all immersed in the composition in the container.

The soil piece was immersed in the hard surface liquid detergent composition in the container for 1 minute, and then the soil piece was taken out and rinsed with tap water for 1 minute. At this time, the conditions of rinsing with running water were: the temperature of tap water was 25 ° C., the flow rate was about 4 L / min, and the diameter of the opening of the faucet was about 15 mm. Hold the dirt piece at 45 ° against tap water falling on the dirt piece located 5cm vertically from the opening, and at the upper end where the dirt is not adhered to the dirt piece with the angle fixed Received running water and rinsed the entire cleaning part with tap water flowing over the dirty piece. At this time, the front and back sides were changed every 10 seconds. After completion of rinsing, the soil piece was dried, and the mass was measured with a 4-digit balance (z). The cleaning rate was determined by the following formula.
