The mass of a polypropylene test piece (manufactured by Engineering Test Service Co., Ltd.) of 30 mm (horizontal) x 80 mm (vertical) x 1 mm (thickness) was measured using a 4-position balance (p). The two sides of the polypropylene test piece manufactured above were uniformly coated with model stains to a height of 50 mm from the lower end so that the total of both sides became 0.02 to 0.04 g, as the stain pieces. The quality of the stained part was measured using a 4-position balance (q). (2) Order of evaluation 50 g of each detergent composition described in Table 1 was added to a 50 mL container (a cylindrical shape having an inner diameter of 35 mm × a height of 68 mm), and then one stain was placed in the container so that It is in contact with the composition described above. At this time, the stained part of the stained piece is completely immersed in the above composition in the container. After the stain member is immersed in the detergent composition in the container for 1 minute, the stain member is taken out and rinsed with running water for 1 minute. At this time, the conditions for running water washing are: the temperature of the tap water is 25 ° C, the flow rate is about 4 L / min, and the diameter of the opening of the faucet is about 15 mm. Hold the stained piece at a 45 ° angle with respect to the tap water dripping down to the stained piece located 5 cm vertically downward from the opening, and use the upper end of the stained piece without the stain attached when the angle is fixed. Part of it receives running water, and the entire one side of the cleaned part is rinsed with tap water flowing on the stained part. At this time, the front and back are changed every 10 seconds, and rinse is performed alternately. After the rinsing was completed, the stained article was dried, and thereafter, the mass was measured with a 4-position balance (r). The cleanliness rate was calculated by the following formula. Cleaning rate (%) = {(q) － (r)} / {(q) － (p)} × 100 In addition, the same method as above is used to determine the cleaning agent combination in which the stained article is immersed in the container The cleanliness rate in the case of 1 hour.
