Next, a model cleaning solution in which each composition was diluted was prepared using ion-exchanged water and water having a predetermined hardness. The following cleaning power evaluation was performed using the obtained composition. The results are shown in Tables 1 and 2. The pH of the model washing solution at 25 ° C. was 10-11. In addition, the numerical value of the composition in a table

Lauric acid 0.44 mass%, myristic acid 3.09 mass%, pentadecanoic acid 2.31 mass%, palmitic acid 6.18 mass%, heptadecanoic acid 0.44 mass%, stearic acid 1.57 mass%, oleic acid 7.75 mass%, triolein 13.06 mass%, n-hexadecyl palmitate 2.18 mass%, squalene 6.53 mass%, egg white lecithin liquid crystal 1.94 mass%, Kanuma red clay 8.11 mass%, Carbon black 0.01% by mass, tap water balance.
• Examples 9 to 12 and Comparative Example 7 Evaluation of detergency of mud-stained artificially contaminated cloth
• Four mud-stained artificially contaminated cloths (25 g in total) were put in 600 mL of the above model cleaning solution, and immersed at 20 ° C. for a predetermined time. Thereafter, it was washed at 20 ° C. for 10 minutes at 100 rpm / min with a targotometer. After washing, it was rinsed with tap water, dehydrated and naturally dried at room temperature, and the detergency was measured by the same method as the above-mentioned “Eli Model Artificial Contaminated Cloth”. The results are shown in Table 3.
• Kanuma Horticultural Akadama soil was dried at 120 ° C. ⁇ 5 ° C. for 4 hours and then pulverized, and a 150 mesh (100 ⁇ m) pass was dried at 120 ° C. ⁇ 5 ° C. for 2 hours. Thereafter, 150 g of the dried soil was dispersed in 1 liter of parklens, and a gold width # 2023 cloth was brought into contact with this dispersion. Then, brushing was performed to remove the dispersion liquid, and the excessively adhered dirt was removed to prepare a mud dirt-stained cloth.
