"Examples 1-35, Comparative Examples 1-6"
According to the compounding composition shown in Tables 1-4, the dishwashing detergent of each example was prepared with the manufacturing method shown below (when there is an unmixed component, the component is not blended).
The unit of the compounding amount in Tables 1 to 4 is mass%, and all the components indicate the equivalent amount of pure component. In addition, the detergent for tableware of each example was prepared by balancing with ion-exchange water so that the sum total of each component of Tables 1-4 might be 100 mass%.

1000 g of tableware detergents having the compositions shown in Tables 1 to 4 were prepared by the following procedure.
Put a component (A), component (B), component (C), component (D), and an optional component into a 1L beaker and use a three-one motor (made by Shinto Kagaku Co., Ltd., product name “FBL600”). Stir until homogeneous. Ion exchange water is added until the total amount reaches 95% by mass, and after adding an appropriate amount of a pH adjuster so that the pH of the resulting mixture at 7.0C is 7.0, the total amount is 100% by mass. Then, ion-exchanged water was further added and stirred until uniform to obtain a dishwashing detergent.
The pH is adjusted to 25 ° C., and a glass electrode type pH meter (product name “HM-30G” manufactured by Toa DKK Corporation) is used to immerse the glass electrode directly in the mixed solution 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”.
About the cleaning agent for tableware of each case, the cleaning power and foam elasticity were evaluated as follows. The results are shown in Tables 1-4.

<Evaluation of cleaning power>
300 mg of beef tallow (manufactured by Wako Pure Chemical Industries, Ltd.) was uniformly applied to a polypropylene round plate having a diameter of 25 cm, 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 dishwashing detergent of each example was dropped into the center of the bowl. Immediately after that, dip a dishwashing sponge (Sumitomo 3M Co., Ltd., trade name “Scotch Bright”), which has been weighed in advance, into the bowl and visually check until the dishwashing agent is completely dissolved. Stir well. After stirring, take out the sponge while weighing with an electronic balance so that the amount of the solution soaked in the sponge is 40 g. It was scrubbed by moving it so as to draw a circle 10 times with a sponge foamed in a dish. 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).
◎◎: Beef tallow residue is not visually confirmed, and is not null when the dish is rubbed with a finger.
◎: The remaining residue of beef tallow is not visually confirmed, but is slightly nullified when the dish is rubbed with a finger.
○: The remaining dirt of beef tallow cannot be visually confirmed, but is slightly nullified when the dish is rubbed with a finger.
[Delta]: The remaining residue of beef tallow is slightly confirmed by visual observation, and becomes slightly null when the dish is rubbed with a finger.
X: The remaining dirt of beef tallow is considerably confirmed by visual observation, and when the dish is rubbed with a finger, it becomes quite null.

<Evaluation of foam elasticity>
The dirt dish was scrubbed in the same manner as the evaluation of the cleaning power. The foam quality, elasticity and defoaming property during washing were visually confirmed, and the foam elasticity was evaluated according to the following evaluation criteria (five-step evaluation).
A: The foam quality is very creamy and elastic, and hardly defoams even during washing.
A: The foam quality is fairly creamy and elastic, but slightly disappears during washing.
○: Although the foam quality is creamy and elastic, it is slightly defoamed during washing.
(Triangle | delta): A foam quality is quite coarse and it defoams considerably during washing | cleaning.
X: The foam quality is very coarse, and the foam is extremely removed during washing.

In Tables 1 to 4, “balance” refers to the blending amount (mass%) of ion-exchanged water necessary to make 100% by mass of the entire dishwashing detergent.

As is clear from Tables 1 to 3, the dishwashing detergents of each example were excellent in cleaning power and foam elasticity even when diluted with water.
On the other hand, as is apparent from Table 4, the dishwashing detergents of Comparative Examples 1 to 3 that do not contain any of the components (A), (B) and (C) are diluted with water. The foam elasticity was inferior. In particular, the detergents for tableware of Comparative Examples 2 and 3 that did not contain the component (B) or the component (C) were inferior in detergency.
The dishwashing detergents of Comparative Examples 4 and 5 having an A / C ratio of more than 25 were inferior in cleaning power and foam elasticity when used diluted with water.
The dishwashing agent of Comparative Example 6 having an A / C ratio of less than 0.1 was inferior in foam elasticity when used after being diluted with water.
