Embodiment 1～5、 comparative example 1～21
[0057] The prescription of stock solution is shown in Table 1. "(C) Component etc." of Table 1 is specifically shown in Table 2. Moreover, the polyoxyethylene alkyl ether phosphate (salt) in Examples 1-5 is (C)component in this invention.
[0058] The stock solution in Table 1 was diluted with water to a predetermined ratio to prepare a sample solution, and the defoaming property, aluminum discoloration degree, and hard water stability were evaluated. The evaluation results are shown in Table 2. The evaluation method is as follows.
[0059] [Table 1]
[0060]
[0061] (Evaluation method of defoaming property)
[0062] Evaluation was performed by the graduated cylinder method (Silinder method). Specifically, add 95mL of ion-exchanged water to a 100mL stoppered measuring cylinder, add 5mL of stock solution, cover tightly and vibrate vigorously up and down for 5 seconds, and start timing from the time it is placed in a horizontal place. Confirm that the air bubbles on th...
Embodiment 6、7、 comparative example 22、23
[0086] In Example 6 and Comparative Example 22 of Table 3, the compounding prescription (stock solution) intended to be an iron-aluminum dual-purpose detergent is shown, and in Example 7 and Comparative Example 23, the compounded formula (stock solution) intended to be an aluminum-only detergent is shown ( stock solution). And, these stock solutions were diluted with water and evaluated. Specifically, in addition to the above-mentioned defoaming properties and the degree of aluminum discoloration, practical hard water stability (Ca hardness resistance) and rust prevention were evaluated by the method shown below. All the evaluation results are shown in Table 3.
[0087] (Ca resistance hardness)
[0088] The hard water stability is evaluated from the increment of hardness 100 to the hardness of 1000, and the highest hardness without precipitation of calcium salt (scum) is obtained. Specifically, as follows.
[0089] Using the operation of the evaluation method of the above-...
