<Liquid cleaning agent composition for hard surface>
The liquid cleaning composition for a hard surface of the present invention specifies the content of an anionic surfactant having a hydrocarbon group having 8 or more and 21 or less carbon atoms and a sulfate ester group or a sulfonic acid group as the component (b). Thereby, the interaction between the component (a) having a highly hydrophobic dialkyl group and the highly hydrophilic sulfate group and the component (c) which is an amphoteric surfactant can be strengthened. As a result, the surfactant contained in the liquid cleaning composition for a hard surface of the present invention easily permeates into oil stains containing solid fat, and the solid fat can be easily peeled off from the hard surface. It is presumed that the effect of improving the detergency was obtained.
When the liquid cleaning agent composition for a hard surface of the present invention is used in a method of directly contacting the hard surface, the concentration of the surfactant applied to the hard surface is such that the sponge containing water is used to make the hard surface.

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

50 g of a liquid cleaning agent composition for a hard surface was placed in a 50 mL container (a columnar shape having an inner diameter of 35 mm and a height of 68 mm), and then one dirty piece was leaned against the container and brought into contact with the composition. At this time, all the parts of the dirt piece to which the dirt was attached were immersed in the composition in the container.

The dirty piece was left to stand for the time shown in Table 1 in a state of being immersed in the liquid cleaning agent composition for a hard surface in the container, and then the dirty piece was taken out and rinsed with running water for 1 minute. At this time, the conditions for rinsing with running water were that the temperature of tap water was 25 ° C., the flow velocity was about 4 L / min, and the diameter of the opening of the faucet was about 15 mm. Hold the dirt piece at 45 ° to tap water falling on the dirt piece located 5 cm vertically below the opening, and keep the angle fixed at the upper end where the dirt piece is not attached. After receiving running water, the entire surface of the washed part was rinsed with tap water flowing over the dirty piece. At this time, the front and back were changed every 10 seconds and rinsed alternately. After the rinsing was completed, the dirty piece was dried, and then the mass was measured with a 4-digit balance (z). The cleaning rate was calculated by the following formula.
Cleaning rate (%) = {(y)-(z)} / {(y)-(x)} x 100

(2) Detergency (foam immersion evaluation)
A mixture of beef tallow and rapeseed oil at a mass ratio of 9: 1 was prepared and used as a model stain. The mass of a polypropylene test piece of 30 mm (horizontal) × 80 mm (length) × 1 mm (thickness) was measured with a 4-digit balance (x). A model stain was uniformly applied to both sides of the polypropylene test piece from the lower end to a height of 5 cm so as to be 0.02 to 0.03 g in total, and the polypropylene test piece was prepared as a stain piece.

It was sprayed 5 times. The total discharge amount of the composition was about 5 g.

Next, one dirty piece was leaned against the container, and the dirty piece was brought into contact with the foamy liquid cleaning agent composition for a hard surface in the container. At this time, the portion of the dirt piece to which the dirt was attached was completely immersed in the foamy composition in the container. After leaving the dirty piece immersed in foam for the time shown in Table 1, the dirty piece was taken out and rinsed with tap water for 1 minute. At this time, the conditions for rinsing with running water were that the temperature of tap water was 25 ° C., the flow velocity was about 4 L / min, and the diameter of the opening of the faucet was about 15 mm. Hold the dirt piece at 45 ° to tap water falling on the dirt piece located 5 cm vertically below the opening, and keep the angle fixed at the upper end where the dirt piece is not attached. After receiving running water, the entire surface of the washed part was rinsed with tap water flowing over the dirty piece. At this time, the front and back were changed every 10 seconds and rinsed alternately. After the rinsing was completed, the dirty piece was dried, and then the mass was measured with a 4-digit balance (z). The cleaning rate was calculated by the following formula.
Cleaning rate (%) = {(y)-(z)} / {(y)-(x)} x 100
