“Examples 1 to 29, Comparative Examples 1 to 7”
According to the blending compositions shown in Tables 1 to 6, the cleaning compositions of the respective examples were prepared by the following production methods (when there are unblended components, the components are not blended).
The unit of the blending amount in Tables 1 to 6 is% by mass, and all the components indicate the amount in terms of pure content. The cleaning agent in each example was prepared by balancing with the component (E) (ion-exchanged water) so that the total amount of each component described in Tables 1 to 6 was 100% by mass.

1000 g of the cleaning agent having the composition shown in Tables 1 to 6 was prepared by the following procedure.
300 g of the component (A) and the component (E) were put into a 1 L beaker and stirred with a three-one motor (manufactured by Shinto Kagaku Co., Ltd., product name “FBL600”). Subsequently, the component (B), the component (C), the component (D) and an optional component were added and stirred until they were completely dissolved. After adding an appropriate amount of pH adjuster so that the pH of the obtained mixture at 25 ° C. is 4.5, add component (E) so that the total amount becomes 100% by mass, until uniform. Stir to obtain a cleaning agent.
The pH is adjusted to 25 ° C., and the glass electrode is directly immersed in the mixture using a glass electrode type pH meter (product name “HM-30G” manufactured by Toa DKK Co., Ltd.) for 1 minute. The pH shown after the lapse was measured. The measuring method was performed according to JIS Z 8802: 1984 “pH measuring method”.
Each of the cleaning agents in each example was evaluated by the following evaluation method. The results are shown in Tables 1-6.

<Evaluation of cleaning power>
0.5 g of butter (manufactured by Snow Brand Megmilk Co., Ltd., trade name “Snow Brand Hokkaido Butter”) was evenly applied to a circular flat plate made of polypropylene having a diameter of 25 cm and left at 25 ° C. for 1 hour or longer to prepare a soiled dish.
1 L of tap water at 25 ° C. was added to a plastic bowl having a diameter of 20 cm and a depth of 10 cm, and 10 g of the cleaning agent of each example was dropped into the center of the bowl. Immediately after that, a sponge (manufactured by 3M Japan Co., Ltd., trade name “Scotch Bright”) was immersed in the bowl, and sufficiently stirred while visually checking until the cleaning agent was completely dissolved. After stirring, the sponge was taken out while weighing with an electronic balance so that the amount of the solution soaked in the sponge was 40 g. The sponge thus taken out was whipped 5 times on the above-mentioned dirt dish on which butter had adhered, and then rubbed with the foamed sponge 10 times. After that, the dirt dish was rinsed with tap water. After the rinsed dishes were air-dried for 1 hour, the degree of dirt removal was evaluated according to the following evaluation criteria (5-level evaluation).
◎◎: The remaining dirt of the butter is not visually confirmed, and is not null when the dish is rubbed with a finger.
A: The remaining butter of the butter is not visually confirmed, and is slightly nullified when the dish is rubbed with a finger.
○: The remaining dirt of butter cannot be visually confirmed, but slightly sticks when the dish is rubbed with a finger.
Δ: Slightly left unstained butter on the butter, and slightly rubbed when the dish is rubbed with a finger.
X: The butter | stain residue of a butter | batter is confirmed considerably visually, and when a dish is rubbed with a finger | toe, it will become quite null.

<Deodorizing effect>
0.1 g of sardine oil (commercially available reagent, manufactured by Yoneyama Pharmaceutical Co., Ltd.) was uniformly applied to a circular flat plate having a diameter of 25 cm made of polypropylene and allowed to stand at 25 ° C. for 1 hour or longer to obtain a dirty dish.
1 L of tap water at 25 ° C. was added to a plastic bowl having a diameter of 20 cm and a depth of 10 cm, and 10 g of the cleaning agent of each example was dropped into the center of the bowl. Immediately after that, a sponge (manufactured by 3M Japan Co., Ltd., trade name “Scotch Bright”) was immersed in the bowl, and sufficiently stirred while visually checking until the cleaning agent was completely dissolved. After stirring, the sponge was taken out while weighing with an electronic balance so that the amount of the solution soaked in the sponge was 40 g. The sponge was taken out and foamed 5 times on the above-mentioned soiled dish on which sardine oil was adhered, and then the soiled dish was rubbed 10 times with the foamed sponge. After that, the dirt dish was rinsed with tap water. After the rinsed dishes were air-dried for 1 hour, the presence or absence of odor residue was evaluated by two professional panelists according to the following evaluation criteria (five-level evaluation).
4 points: Fish odor derived from sardine oil is not completely felt.
3 points: Fish odor derived from sardine oil is hardly felt.
2 points: Smell of fish odor derived from sardine oil.
1 point: Fish odor derived from sardine oil is felt considerably.
0 point: Fish odor derived from sardine oil is very felt.

The average score of two professional panelists was determined and evaluated according to the following evaluation criteria.
◎◎: 4 points ◎: 3 to 3.5 points ○: 2 to 2.5 points △: 0.5 to 1.5 points ×: 0 points

In Tables 1 to 6, “metal content” is an amount (metal concentration, mass%) obtained by converting the content of the component (D) contained in 100% by mass of the cleaning agent into a metal content.
Further, the “balance” is the blending amount (mass%) of the component (E) (ion exchange water) necessary for making the entire cleaning agent 100 mass%.
“A1 + A2” is the sum of the amount (mass%) of the component (A1) and the component (A2) in 100% by mass of the cleaning agent (that is, the amount of the component (A) in 100% by mass of the cleaning agent (mass%). )). “A1 / A” is the amount (mass%) of the component (A1) with respect to the total mass of the component (A). “A2 / A” is the amount (% by mass) of the component (A2) with respect to the total mass of the component (A). “A1 / A2 ratio” is a mass ratio represented by “(A1) component / (A2) component”. The “(A + B) / C ratio” is a mass ratio represented by “(((A) component + (B) component) / (C) component” ”. “(A + B) / 2-valent metal content ratio” is a mass ratio represented by “((A) component + (B) component) / divalent metal content contained in liquid detergent for kitchen”. In Examples 1 to 29 and Comparative Examples 1 to 7, the divalent metal contained in the kitchen liquid detergent is derived from the component (D).

As is clear from Tables 1 to 5, the cleaning agents of each Example were excellent in detergency and deodorizing effect even when diluted with water.
In particular, Examples 2 to 6 in which the (A + B) / 2-valent metal content ratio was in the range of 30 to 350 were superior to Examples 1 and 7 in the deodorizing effect.
Examples 4 and 9 to 12 having an (A + B) / C ratio in the range of 2.5 to 60 were superior to Examples 8 and 13 in terms of detergency and deodorizing effect.
In Examples 4 and 21 to 24 in which the A1 / A2 ratio is in the range of 0.2 to 4.5, the deodorizing effect was superior to that in Examples 20 and 25.

On the other hand, as is clear from Table 6, the cleaning agents of Comparative Examples 1 to 4 that do not contain any of the components (A1), (B), (C), and (D) are inferior in the deodorizing effect. It was. In particular, the cleaning agents of Comparative Examples 1, 2, and 4 that did not contain any of the components (A1), (B), and (D) were inferior in cleaning power.
The cleaning agent of Comparative Example 5 using unmodified dimethylpolysiloxane was inferior in cleaning power and deodorizing effect.
The cleaning agent of Comparative Example 6 having an (A + B) / C ratio of 0.75 was inferior in cleaning power and deodorizing effect.
The cleaning agent of Comparative Example 7 having an (A + B) / C ratio of 193.22 was inferior in the deodorizing effect.

The liquid detergent for kitchen of the present invention is excellent in cleaning power and deodorizing effect even when diluted with water.
