[0062]1000 ml of the solutions described in Table 1 below were prepared in a beaker at 80°C and placed in an immersion tester, stirred with a stirring bar at 30 rpm. Put the pure milk stained sample prepared above into the beaker to be tested at 80°C for 15 minutes. The samples were then removed and placed overnight in a humidity cabinet at 30°C and 60% relative humidity. Then, the sample is weighed. Four samples were used for each solution tested.
[0063] The soil removal rate of the soiled samples was obtained gravimetrically and calculated as follows:
[0064] Dirt removal rate%=(the weight of the stained sample before cleaning, the weight of the stained sample after cleaning) / (the weight of the stained sample before cleaning, the weight of the sample before staining)x100
[0065] The soil release rate for each solution tested is reported as the average of the soil release rates for the four samples. The results are shown in Table 1.

[0072] 1000 ml of the solutions described in Table 2 below were prepared in a beaker at 80°C and placed in an immersion tester, stirred with a stirring bar at 30 rpm. Put the pure milk stained sample prepared above into the beaker to be tested at 80°C for 10 minutes. The samples were then removed and placed overnight in a humidity cabinet at 30°C and 60% relative humidity. Then, the sample is weighed. Three samples were used for each solution tested.
[0073] The soil release rate for each solution tested is reported as the average of the soil release rates for the three samples. The results are shown in Table 2.

Embodiment 10-13
[0077] 1000 ml of the solutions described in Table 3 below were prepared in a beaker at 80°C and placed in an immersion tester, stirred with a stirring bar at 30 rpm. Put the pure milk stained sample prepared above into the beaker to be tested at 80°C for 10 minutes. The samples were then removed and placed overnight in a humidity cabinet at 30°C and 60% relative humidity. Then, the sample is weighed. Seven samples were used for each solution tested.
[0078] The soil release rate for each solution tested is reported as the average of the soil release rates for the seven samples. The results are shown in Table 3.
