＜27＞ Use of a composition according to any one of <1> to <18> as a germicidal detergent composition.

Example The germicidal detergent composition shown in Table 1 was prepared and evaluated as follows. The results are shown in Table 1.

[Evaluation of detergency] Approximately 1 mg/cm ² of rapeseed oil (manufactured by Wako Pure Chemical Industries, Ltd.) was applied to a test piece weighed in advance using an electronic balance with 4 decimal places (Engineering Test Service Manufactured by the company, SUS304, 1 mm × 25 mm × 70 mm) (mass x), use a balance with 4 decimal places to weigh (mass y). Use a Pump Foamer (for Biore hand sanitizer, manufactured by Kao Co., Ltd.) to spray 2 ml of the antiseptic detergent composition in a foam form onto each test piece after applying oil, and let it sit flat for 20 minutes. Rinse the test piece after cleaning for 20 minutes with tap water at 25°C for 1 minute using a Leanuts tester (water volume: 700 ml, rotating wing speed: 300 rpm). After rinsing, air-dry for one day and night in an environment with a temperature of 20°C and a humidity of 40%. The mass of the cleaned test piece is weighed using an electronic balance with 4 decimal places (mass z). Using the masses x, y, and z, the cleaning rate is obtained by the following formula. Table 1 shows the results of the cleaning rate when rapeseed oil was applied. In this evaluation, the cleaning rate is preferably 75% or more, and the one with a larger value is better. Cleaning rate (%) = {(y)-(z)}/{(y)-(x)}×100

[Evaluation of bactericidal power] (1) Put 10 mL of LB medium into a tissue culture flask, use a platinum ear to take out the bacteria (Staphylococcus aureus, Escherichia coli) cultured in the Petri dish, and put it into the LB medium. (2) Incubate the above flask at 200 rpm and 37°C for 16 hours. (3) Transfer the above LB culture medium into a 50 mL centrifuge tube, and centrifuge at 4000 rpm and 15°C for 10 minutes. (4) Discard the LB medium of the supernatant, add 10 mL of physiological saline, and centrifuge again under the same conditions as (3). (5) Discard the physiological saline solution of the supernatant and add physiological saline to prepare a bacterial solution of OD1. (6) Use the solution prepared in (5) to prepare a bacterial solution of BSA0.5% and OD0.001. (7) Add 0.3 mL of the bacterial solution prepared in (6) on an 8 cm×3 cm×0.1 cm SUS304 plate and spread evenly. (8) Add 0.3 mL of the sterilizing detergent composition to the plate in (7), spread evenly and let stand for 30 minutes. (9) Flow the remaining liquid on the plate into a wiping rod filled with 1 mL of LP reaction stop solution, and wipe it out by wiping the wiping rod on the plate. (10) Take out the liquid from the wipe stick and dilute it in stages every 10 times. (11) Add 0.1 mL of the stepwise diluted solution to the standard agar medium and spread it with a spreading rod. (12) Cultivate the culture prepared in (11) at 37°C for 24 hours and count the number of colonies, and set it as the number of viable bacteria (cfu/mL). The values converted into Log (cfu/mL) are shown in the table. In this evaluation, Log (cfu/mL) is preferably 2 or less for both Staphylococcus aureus and Escherichia coli, and the one with a smaller separation coefficient value is more preferred.
