[0025] The cleaning composition of the present invention is an aqueous cleaning composition containing components (a), (b), (c), (d), and further optionally component (e) in the above-specified content ratios. That is, the cleaning composition of the present invention contains water. The water content ratio is not particularly limited as long as it does not inhibit the effects of the cleaning composition of the present invention, but is preferably 70% by mass or more, more preferably 80% by mass or more, and still more preferably 85% by mass or more.

[0027] The pH of the cleaning composition of the present invention is not particularly limited as long as it does not inhibit the effects of the present invention, but is preferably 8.0 to 10.0, and more preferably 9.0 to 10.0.

[0028] The cleaning composition of the present invention preferably has a bactericidal power. The bacteria to be sterilized are not limited to specific bacteria, and examples include bacteria with potential pathogenicity such as Escherichia coli, Salmonella spp., Pseudomonas aeruginosa, and Staphylococcus aureus.

[0029] Furthermore, the cleaning composition of the present invention preferably has antiviral properties. The viruses to be targeted for antiviral action are not limited to specific viruses. For example, viruses having an envelope structure and potential pathogenicity such as the novel coronavirus (SARS-CoV-2) and influenza virus are suitable targets.

[0030] Next, a cleaning method using the cleaning composition of the present invention will be described. As cleaning methods, mainly the following two forms can be mentioned according to the difference in the method of attaching the cleaning composition to the article to be cleaned.

[0031] As a first usage method of the cleaning composition of the present invention, for example, there is a method of filling the cleaning composition into a spray bottle to make a spray bottle-type cleaner, spraying the cleaning composition on the surface of the article to be cleaned, and then wiping it off with a cloth or the like. Note that the cleaning composition may be brought into contact with the article surface and wiped off immediately, but preferably it is left for 30 seconds or more, more preferably 1 minute or more, and even more preferably 2 minutes or more before being wiped off. Note that the upper limit of the leaving time is not particularly limited, but for example, it is 30 minutes or less, preferably 5 minutes or less, and even more preferably 3 minutes or less.

[0032] As a second usage method of the cleaning composition of the present invention, for example, there is a method of using a wet wiper in which the cleaning composition is contained in a fiber sheet and wiping the surface of the article to be cleaned with the wet wiper.

[0033] Examples of the article to be cleaned with the cleaning composition of the present invention include articles having a hard surface. Specifically, tables, chairs, cooking utensils, kitchen appliances, food manufacturing equipment, household appliances, toilets, window glass, etc. can be mentioned. Examples of the material of the article to be cleaned include stainless steel, cast iron, plated steel sheets, aluminum, brass, pottery, and plastics. In recent years, acrylic plates are often used especially for infection prevention measures, but it is known that the surface of the acrylic resin whitens due to solvents such as ethanol. In the cleaning composition of the present invention, whitening of the acrylic resin surface is suppressed and wiping marks are also less likely to remain. Therefore, the cleaning composition of the present invention is particularly preferably used for cleaning the acrylic resin surface. Note that when the cleaning composition of the present invention is used for cleaning the acrylic resin surface, it can also be used for cleaning other articles.

[0034] The present invention will be described in detail below with reference to Examples and Comparative Examples. Unless otherwise specified, the values of each component in Table 1 are in mass%.

[0035] Details of each component used in the preparation of the detergent composition are as follows. Component (a): Benzalkonium chloride (trade name Cation G-50 manufactured by Sanyo Chemical Industries, Ltd.) Component (b): Alkylamine oxide (trade name Anhtol 20N manufactured by Kao Corporation) Component (b): Fatty acid amide propylamine oxide (product name Pyonin C-151 manufactured by Takemoto Yushi Co., Ltd.)

Component (e): Sodium carbonate (trade name Dense Ash manufactured by Tokuyama Central Soda Co., Ltd.) Component (e): Sodium hydrogen carbonate (trade name Sodium Bicarbonate manufactured by AGC Inc.)

[0036] <Preparation of Detergent Composition> In an environment at room temperature (25°C), each component was mixed so as to have the composition shown in Table 1, and detergent compositions of Examples 1 to 4 and Comparative Examples 1 to 8 were prepared.

[0037] [Detergency] After evenly attaching sebum to the surface of an acrylic plate measuring 160 mm in length, 180 mm in width, and 2 mm in thickness by touching it with human hands, the detergent composition was sprayed 3 times (3 ml), gently wiped with a towel, and then the surface of the acrylic plate was observed. The detergency was evaluated according to the following criteria. The results are shown in Table 1. 〇: It had fallen off well to the extent that dirt could not be confirmed. ×: A small amount of dirt remained.

[0038] [Damage to the Acrylic Resin Surface] An acrylic plate with a length of 75 mm, a width of 20 mm, and a thickness of 2 mm was immersed in the cleaning agent composition, allowed to stand at 50 °C for 72 hours, the surface of the acrylic plate was observed, and evaluation was carried out according to the following criteria. The results are shown in Table 1. 〇: No change △: Changes can be seen on the surface ×: The surface is whitened

[0039] [Drying speed] The cleaning composition was sprayed once (1 ml) on the surface of an acrylic plate with a length of 160 mm, a width of 180 mm, and a thickness of 2 mm, gently wiped off with a tissue, and then the speed until drying was evaluated according to the following criteria. The results are shown in Table 1. 〇: Dries in a short time △: Dries, but is slightly slow ×: Does not dry easily

[0040] [Residual wiping marks] After the surface of an acrylic plate with a length of 160 mm, a width of 180 mm, and a thickness of 2 mm was evenly touched by hand to attach sebum, the cleaning composition was sprayed three times (3 ml), gently wiped off with a tissue, and then the surface of the acrylic plate was observed to evaluate the remaining wiping marks according to the following criteria. The results are shown in Table 1. 〇: Almost no wiping marks can be seen ×: Wiping marks can be seen

[0041] [Bactericidal power] (Bactericidal effect against Escherichia coli) Escherichia coli (Escherichia coli NBRC3301) was inoculated into SCD broth medium and cultured at 30 °C for 24 hours to obtain a bacterial solution. Next, the cleaning agent composition and the bacterial solution were mixed at a ratio of 9:1 (by volume), contacted for 1 minute, then 100 μl was transplanted into 900 μl of SCDLP medium, cultured at 35 °C for 48 hours, and the survival or death of the bacteria was measured by turbidity. The evaluation criteria are as follows. The results are shown in Table 1. 〇: Escherichia coli was killed. ×: Escherichia coli was not killed.

[0042] (Bactericidal effect against Staphylococcus aureus) Staphylococcus aureus (Staphylococcus aureus NBRC 12732) was inoculated into SCD broth medium and cultured at 30 °C for 24 hours to obtain a bacterial solution. Next, the detergent composition and the bacterial solution were mixed at a ratio of 9:1 (by volume), contacted for 1 minute, and then 100 μl was transplanted into 900 μl of SCDLP medium. After culturing at 35 °C for 48 hours, the viability of the bacteria was measured by turbidity. The evaluation criteria are as follows. The results are shown in Table 1. 〇: Escherichia coli was killed. ×: Escherichia coli was not killed.

[0043] [Evaluation of the Inactivation Effect of the Novel Coronavirus] The evaluation of the inactivation effect against the novel coronavirus was performed by measuring the viral infectivity titer by the TCID 50 method. As the test virus, the SARS-CoV-2 JPN / TY / WK-521 strain (hereinafter referred to as "SARS-CoV-2") was used. In addition, as the host cell, a transformed cell line derived from African green monkey kidney (Vero E6 / TMPRSS2 cells) in which the serine protease TMPRSS2 was forcibly expressed was used. Vero E6 / TMPRSS2 cells suspended in Dulbecco's modified Eagle's medium (DMEM) supplemented with 5% fetal bovine serum and 1 mg / ml G418 were dispensed at 0.1 mL per well into a 96-well microplate and cultured overnight at 37 °C and 5% CO 2 under the conditions to obtain monolayer cultured cells. Although NITE (National Institute of Technology and Evaluation) has published effective surfactants, it is important to verify them in an actual mixed system because surfactants form mixed micelles.

[0044] (Measurement of Infectivity Titer) As the test virus solution, SARS-CoV-2 was log 10 TCID 50A suspension prepared to have a concentration of 8 / ml was used. 0.03 ml of the test virus solution was added to 0.03 ml of each composition and allowed to sensitize at room temperature for 1 minute. Then, this solution was added to 0.54 ml of DMEM (DMEM / F2 / G418) supplemented with 2% fetal bovine serum and 1 mg / ml G418 to obtain a test solution. Furthermore, the test solution was serially diluted 10-fold using DMEM / F2 / G418. 0.1 ml of each dilution was inoculated into 4 wells at each dilution step and cultured at 37 °C, 5% CO 2 under the conditions for 3 days. After culturing, the presence or absence of cell degeneration was determined, and the viral infectivity titer (TCID 50 / ml) was calculated by the Reed-Muench method. The difference (Δlog 10 TCID 50 / ml) from the infectivity titer measured using phosphate buffer as a control was used to evaluate the virus-inactivating effect of each test solution. The evaluation criteria are as follows. The results are shown in Table 1. 〇: The difference from the infectivity titer of the control is 4 or more

[0045]

Table 1

[0046] In Table 1, “-” indicates that the evaluation was not performed.

[0047] As shown in Table 1, the detergent compositions of Examples 1 to 5 contain a quaternary ammonium salt as component (a), an amphoteric surfactant as component (b), an alkyl glucoside as component (c), and ethanol as component (d). The content of component (a) is 0.03 to 0.06% by mass, the content of component (b) is 0.04 to 0.08% by mass, the content of component (c) is 0.08 to 0.12% by mass, the content of component (d) is 3 to 20% by mass, the total content of components (a), (b), and (c) is 0.25% by mass or less, and the relationship of the content of component (c) > the content of component (b) > the content of component (a) is satisfied, and the relationship of the content of component (c) / the total content of components (a) and (b) = 0.8 to 1.5 is satisfied. The detergent compositions of Examples 1 to 5 had excellent detergency, and furthermore, damage to the acrylic resin surface was suppressed, and wiping marks were less likely to remain. Furthermore, the detergent compositions of Examples 1 to 4 had a high drying speed and excellent bactericidal power. In addition, further, taking the detergent composition of Example 2 as a representative example, when the antiviral property evaluation against the novel coronavirus (SARS-Co-V2) was carried out, it had antiviral property.

[0048] On the other hand, the detergent compositions of Comparative Examples 1 to 8 did not satisfy the composition of the present invention. The detergent compositions of Comparative Examples 1, 3, 6, and 7 had inferior detergency. In addition, the detergent composition of Comparative Example 8 damaged the acrylic resin surface. In addition, wiping marks remained in the detergent compositions of Comparative Examples 2 to 6. Usually, turbidity occurs after 24 hours in the measurement of the sterilization effect, but in Comparative Example 6, it was transparent after 24 hours, and turbidity was confirmed after 48 hours. This is presumably because the quaternary ammonium salt exhibited bactericidal power and reduced the initial bacterial count, but could not be completely killed. From this, it is considered that this detergent composition exhibited high bactericidal power and detergency while suppressing damage to the acrylic resin surface due to the synergistic effect of the quaternary ammonium salt and ethanol.
