(1-1) Oil stain cleaning power An oil stain solution is prepared by dissolving 20 g of fat and oil mixed with beef tallow and soybean oil in a volume ratio of 1: 1, 0.25 g of monoolein and 0.1 g of oil red in 60 ml of chloroform. A set of 6 clean slide glasses is used, and each mass is measured up to 1 mg. Immerse the slide glass one by one in an oil stain at 25 ± 1 ° C. to about 55 mm for about 2 seconds. The accumulation of oil stains adhering to the lower part of the slide glass is sucked up using a clean cloth or filter paper such as gauze, and the oil stains are uniformly adhered, air-dried at 25 ± 1 ° C., and the mass is measured. The model soiled glass piece is used for the test within 1 hour to 2 hours in the air drying period. At this time, the oil dirt adhesion amount per 6 pieces of model dirt glass pieces is set to 0.140 ± 0.010 g.
[0018]
Six sets of this model dirty glass piece are washed at 25 ° C. ± 2 ° C. for 5 minutes using a modified rinatu washer and rinsed with ion exchange water at 25 ± 2 ° C. for 30 seconds. The glass pieces that have been rinsed are air-dried for a whole day and night. The evaluation of the cleaning power is calculated from the weight of the model dirt glass piece before and after cleaning. That is, the weight difference before and after cleaning is obtained, and the cleaning rate (%) is calculated by the following formula.
Cleaning rate (%) = (weight before cleaning−weight after cleaning) / fouling adhesion amount × 100
The cleaning rate of each of the six glass pieces was determined, and the average value of the four cleaning rates excluding the maximum and minimum values was taken as the cleaning rate of the composition.
[0019]

A clean glass slide is immersed in a protein soil solution at 25 ° C. ± 1 ° C. for about 2 seconds to a point of about 55 mm. The protein dirt pool adhering to the lower part of the slide glass is blotted with a clean cloth or filter paper such as gauze, and the protein dirt is uniformly adhered and air-dried at 25 ± 1 ° C. This is repeated once again, and after removing the dirt on one side completely, it is air-dried and denatured at 110 ° C. for 1 hour to obtain a test piece. This test piece is used for the test within 12 hours to 24 hours. The specimens are washed for 5 minutes at 25 ° C. ± 2 ° C. using a Leanut modified washer and rinsed with ion exchange water at 25 ± 2 ° C. for 30 seconds. After rinsing, drying at 70 ° C. for 30 minutes, coloring with 1% by weight erythrosine solution, measuring the colored area (S 1 ) by photographic judgment, and the washing rate from the initial (before washing) protein stain adhesion area (S 0 ) (%) Is calculated by the following formula.
