<Foaming power>
The composition was diluted 30 times with 3.5 ° DH hard water, and 3 g of foam was prepared in a 500 ml graduated cylinder using a pump former (one 200 mesh), and the volume of foam (ml) was determined from the scale of the graduated cylinder. Reading was taken as foaming power.

<Evaluation of ease of removal of Nurtsuki>
A commercially available sponge (trade name: Kikuron A, Kikuron Co., Ltd.) was impregnated with 1 g of the composition and 30 g of tap water adjusted to 25 ° C. and foamed by hand 5 times. 5 sheets of the polypropylene plate were scrubbed. At this time, each surface was rubbed 5 times. Immediately after scrubbing 5 sheets, each sheet was rinsed by hand at a constant speed in flowing water (temperature controlled to 25 ° C.) at 4 L / min until there was no nullness of the detergent. The time (seconds) until the null plate disappears in all five dishes was used as an index of the ease of removing the null plate.
