(1) Artificial soiling cloth The artificial soiling cloth used is 6cm x 6cm cotton / polyester broad blended dyeing cloth (cotton / polyester ratio = 35/65, purchased from Tanigami Shoten). Gravure coating is applied to make 100 mg per sheet.
-Artificial dirt The composition containing the following A, B, C, D, E was made into artificial dirt. Each mass% is a ratio in the artificial dirt of the final composition, and the amount of B was adjusted so that the total was 100 mass%. A: Model sebum soil (mass% in artificial dirt is 0.44 mass% lauric acid, 3.15 mass% myristic acid, 2.35 mass% pentadecanoic acid, 6.31 mass% palmitic acid, 0 heptadecanoic acid 0 .44 mass%, stearic acid 1.6 mass%, oleic acid 7.91 mass%, triolein 13.33 mass%, n-hexadecyl palmitate 2.22 mass%, squalene 6.66 mass% Use)
B: Hard water obtained by weighing 105 mg of calcium chloride dihydrate and dissolving in distilled water to obtain 1,000 ml C: 1.98% by mass of egg white lecithin liquid crystal (11.37 g of arginine hydrochloride in 80 ml of distilled water, histidine 4 20 g and 2.44 g of serine were dissolved, and the pH was adjusted to 5.0 with concentrated hydrochloric acid, and then this solution and egg white lecithin were mixed thoroughly with a mixer. Egg white lecithin liquid crystal product) D: Kanuma Akado 8.11 mass%
E: Carbon black 0.025 mass%

<Cleaning conditions>
The artificially contaminated cloth is placed in a cleaning liquid (30 ° C.) in which 3 g of the cleaning composition for clothing described in Table 2 is added to 1 liter of water having a hardness of 10 ° dH (Ca / Mg = 6/4, mass ratio). I put five. Next, a 6 cm × 12 cm cotton / polyester broad blended dyeing cloth was introduced, and the bath ratio was adjusted to 20 L / g. Washing was performed with a tartometer at 180 rpm for 3 minutes.
The detergency was evaluated by visual observation of the degree of soiling before and after cleaning of the raw cloth before contamination and the artificially contaminated cloth. The dirt adhering to the test cloth before washing was washed with the garment detergent composition shown in Table 2 to reduce the remaining degree of dirt, which was a satisfactory level as a detergent.
