Among these, amine oxide surfactants having one hydrocarbon group having 15 or more carbon atoms, and furthermore, those having R 1c In the germicidal cleaning agent composition of the present invention, the content of an amine oxide surfactant in which R is an alkyl or alkenyl group having 15 or more carbon atoms tends to decrease the germicidal effect of the present invention, and therefore it is preferable that the content of the amine oxide surfactant is small. 1c is an alkyl or alkenyl group having 15 or more carbon atoms, is preferably 20 mass % or less, more preferably 10 mass % or less, even more preferably 5 mass % or less, and still more preferably 1 mass % or less, based on the total content of the (b) component and the (c) component.

[0080] The germicidal cleaning agent compositions shown in Table 1 were prepared and the following evaluations were carried out. The results are shown in Table 1.

[0081] [Evaluation of cleaning power] Rapeseed oil (manufactured by Wako Pure Chemical Industries, Ltd.) was weighed in advance using a four-digit electronic balance and applied to a test piece (manufactured by Engineering Test Services, SUS304, 1 mm x 25 mm x 70 mm) (mass x) at a concentration of approximately 1 mg / cm. 2 After application, the coating was weighed using a four-digit balance (mass y). After the oil application, 2 ml of the germicidal cleaning agent composition was sprayed in foam form on each test piece using a pump former (for Biore Hand Wash, manufactured by Kao Corporation), and the test piece was left to stand flat for 20 minutes. After 20 minutes of cleaning, the test piece was rinsed for 1 minute with tap water at 25°C using a Leanats tester (water volume 700 ml, impeller rotation speed 300 rpm). After rinsing, the test piece was air-dried overnight in an environment of temperature 20°C / humidity 40%, and the mass of the test piece after cleaning was weighed on a four-digit electronic balance (mass z). The cleaning rate was calculated using the masses x, y, and z according to the following formula. The results of the cleaning rate when rapeseed oil was applied are shown in Table 1. In this evaluation, the cleaning rate is preferably 75% or more, and the higher the value, the more preferable. Cleaning rate (%) = {(y)-(z)} / {(y)-(x)} x 100

[0082] [Evaluation of bactericidal activity] (1) 10 mL of LB medium was placed in a tissue culture flask, and the bacteria (Staphylococcus aureus, Escherichia coli) cultured in a petri dish were removed with a platinum loop and placed in the LB medium. (2) The flask was cultured at 200 rpm and 37° C. for 16 hours. (3) The above LB medium was transferred to a 50 mL centrifuge tube and centrifuged at 4,000 rpm, 15° C., and 10 minutes. (4) The supernatant LB medium was discarded, 10 mL of physiological saline was added, and the mixture was centrifuged again under the same conditions as in (3). (5) The supernatant saline was discarded, and saline was added to prepare a bacterial solution of OD1. (6) The solution prepared in (5) was used to prepare a bacterial solution containing 0.5% BSA and an OD of 0.001. (7) 0.3 mL of the bacterial solution prepared in (6) was added to a SUS304 plate measuring 8 cm x 3 cm x 0.1 cm and spread evenly. (8) 0.3 mL of the germicidal cleaning agent composition was added to the plate in (7), spread evenly, and left to stand for 30 minutes. (9) The liquid remaining on the plate was poured onto a wiping stick containing 1 mL of LP stopping solution, and the plate was swabbed with the wiping stick to wipe it off. (10) The liquid was removed from the wipe and serially diluted 10-fold. (11) 0.1 mL of the serially diluted solution was added to standard agar medium and spread using a Conlarge stick. (12) The medium prepared in (11) was cultured at 37°C for 24 hours, and the number of colonies was counted to obtain the viable cell count (cfu / mL). The values ​​converted to Log(cfu / mL) are shown in the table. In this evaluation, it is preferable that the Log(cfu / mL) is 2 or less for both Staphylococcus aureus and Escherichia coli, and the smaller the value for each, the more preferable.
