Description

TECHNICAL FIELD

[0001] The present application relates to an antifungal agent composition for a hard surface, and a cleaning method for a hard surface. In particular, it relates to an antifungal agent composition for a hard surface of a water use place such as a toilet, a bathroom, a sink, and the like. BACKGROUND

[0002] In a toilet, a bathroom, a sink, and the like, which are devices of a water use place in a household, water droplets adhere to and remain on the surface of the material of the device after use due to splashing of water from a faucet or a shower, and the like, and are likely to cause mold generation. For example, in a toilet, as dirt that often occurs inside a toilet bowl, blackening, yellowing, limescale, and the like can be exemplified, and it is considered that blackening is caused by a specific type of mold, and mold bodies appear darker by adhering to the surface and developing to a certain amount or more. This blackening is mostly generated at the back of the periphery of the bowl portion of a flush toilet, a portion where cleaning water flows, and the vicinity of a water seal portion, for example.

[0003] Against this blackening dirt, a method of removing it using mechanical force such as a brush, or a method of bleaching it with a mold remover such as sodium hypochlorite, or the use of a fixed cleaner for the purpose of preventive effect (a method of being provided to the upper cover portion of a water storage tank of a flush toilet or being put into the water storage tank, and the like) has been performed in the past. However, in the background of a reduction in housework required time with an increase in dual-income households, or an increase in the sense of burden of housework with an increase in the elderly population, there is a strong demand for the convenience of cleaning of a hard surface of a water use place such as a toilet, a bathroom, a sink, and the like, and the persistence of the effect of preventing the generation of blackening dirt caused by mold.

[0004] In Japanese Patent Application Publication No. 2015-140331, a microbicidal composition that can exert an excellent sterilizing effect on microorganisms in a bathroom and the like by using an aromatic alcohol such as benzyl alcohol and a glycol ether in combination is disclosed.

[0005] In Japanese Patent Application Publication No. 2019-81723, a hard surface moldicide composition that uses a sterilizing agent and sodium sulfate as a penetration accelerator for mold in combination is disclosed.

[0006] In Japanese Patent Application Publication No. 2019-81724, a hard surface moldicide composition that uses an aromatic alcohol and an aliphatic alcohol as a penetration accelerator for mold in combination is disclosed.

[0007] In Japanese Patent Application Publication No. 2011-190305, a cleaner composition for a hard surface that contains a partially saponified polyvinyl alcohol not containing a structural unit having a cationic group or an amino group, a surfactant selected from an anionic surfactant, a nonionic surfactant, and an amphoteric surfactant, and a mold inhibitor, and is excellent in mold resistance is disclosed. SUMMARY

[0008] Patent Document 1 is a technology for which bactericidal activity against bacteria such as Escherichia coli or Staphylococcus aureus is excellent, but there is no mention of effectiveness against fungi such as molds for which the cell wall is thick and it is difficult for agents to effectively act. In addition, Patent Documents 2 and 3 are technologies for which the immediate effectiveness of mold resistance is improved using a permeation accelerator for mold cell walls, but the inhibitory effect on mold generation after cleaning is not clear. In Patent Document 4, a technology for which the drying speed on a hard surface is improved by combining a mold inhibitor-containing cleaner with polyvinyl alcohol, and mold resistance is excellent, but from the viewpoint of the persistence of the mold-preventing effect, the present inventors believe that there is room for further improvement.

[0009] The present application provides a hard-surface antifungal agent composition for which the persistence of the effect of inhibiting the generation of discoloration (particularly blackening) of a hard surface caused by fungi such as molds is excellent, and a hard-surface cleaning method using the same.

[0010] The present application relates to a hard-surface antifungal agent composition containing the following (a) component, (b) component, (c) component, and water, and the mass ratio (c) / (b) of the content of the (b) component to the content of the (c) component is 0.003 or more and 0.25 or less,

[0011] The (a) component is an antifungal agent.

[0012] The (b) component is a foaming surfactant (except for the (a) component).

[0013] The (c) component is a water-soluble polymer.

[0014] In addition, the present application relates to a hard-surface cleaning method in which the above-described hard-surface antifungal agent composition of the present application is brought into contact with a hard surface.

[0015] In addition, the present application relates to a method for inhibiting the generation of discoloration of a hard surface caused by fungi, in which the above-described hard-surface antifungal agent composition of the present application is brought into contact with a hard surface.

[0016] In addition, the present application relates to a method for improving the residual property of the (a) component on a hard surface, in which the above-described hard-surface antifungal agent composition of the present application is brought into contact with a hard surface.

[0017] In addition, the present application relates to a method for inhibiting the generation of discoloration of a hard surface caused by fungi, in which a liquid composition containing the above-described (a) component, (b) component, (c) component, and water, and the mass ratio (c) / (b) of the content of the (b) component to the content of the (c) component is 0.003 or more and 0.25 or less is brought into contact with a hard surface.

[0018] [Effects of the Invention]

[0019] According to the present application, there is provided a hard surface antifungal agent composition whose effect of inhibiting the occurrence of discoloration (particularly blackening) of a hard surface caused by fungi such as mold is excellent in persistence, and a hard surface cleaning method using the same. DETAILED DESCRIPTION

[0020] The reason why the hard surface antifungal agent composition and the hard surface cleaning method using the same according to the present application are excellent in the persistence of the effect of inhibiting the occurrence of discoloration (particularly blackening) of a hard surface caused by fungi such as mold is not necessarily clear, but is presumed as follows.

[0021] In order to inhibit the occurrence of discoloration (particularly blackening) and to make the effect thereof persistent, in addition to having a sterilizing effect on specific types of fungi such as mold, it is important to inhibit the propagation of new fungi such as mold. For example, in the bowl of a toilet, with respect to fungi such as mold that occur in the upper portion of the water seal portion, the problem is considered to be that the active base agent is not sufficiently retained in the upper portion of the water seal portion and the effect is not made persistent. However, in the vicinity of the water seal portion, in addition to the active base agent being easily washed away by the running water after use, the active base agent is easily diluted due to contact with water, and thus the action is not sufficient. The hard surface antifungal agent composition according to the present application, by containing the (b) component and the (c) component at a specific ratio, makes the (a) component, which is an antifungal agent, preferably an antimold agent, remain on the hard surface for a long time, and acts on fungi such as mold persistently. In particular, in the case where the hard surface antifungal agent composition according to the present application is applied to the hard surface in the form of a foam, since the (b) component and the (c) component can form a stable foam, the (a) component can remain on the hard surface, particularly the upper portion of the water seal portion of the toilet, for a long time and act. Furthermore, it is considered that by the (a) component persistently remaining on the hard surface even after the running water, and the (c) component persistently remaining on the hard surface even after the running water, the surface is hydrophilized, and thus the propagation of fungi such as mold is inhibited. By the above action, it is presumed that the occurrence of discoloration (particularly blackening) is inhibited by the persistence of the antifungal property, particularly the antimold property, and the persistence of the effect thereof is obtained.

[0022] Further, in the present application, the antifungal agent means an agent that can inhibit the propagation of fungi, which include mold (filamentous fungi) and yeast (yeast-like fungi) classified. In addition, the antimold agent means an agent that can inhibit the propagation of mold.

[0023] [Hard surface antifungal agent composition]

[0024] The hard surface antifungal agent composition according to the present application is excellent in the persistence of the effect of inhibiting the occurrence of discoloration of a hard surface caused by fungi such as mold, particularly the persistence of the effect of inhibiting the occurrence of blackening caused by mold, and thus can be a hard surface antimold agent composition.

[0374] [Preparation of antifungal agent composition for hard surface]

[0375] Using each component shown in Tables 1 and 2, the antifungal agent composition for hard surface of the composition shown in Tables 1 and 2 was prepared according to the method shown below. In obtaining the antifungal agent composition for hard surface of Tables 1 and 2, first, the (a) to (e) components, the perfume were added in ion exchange water so as to become the compounding amount described in Tables 1 and 2, and these were dissolved at room temperature (25°C). After compounding, hydrochloric acid and / or sodium hydroxide were added as a pH adjuster, and the pH was adjusted to the value described in Tables 1 and 2. Further, the pH was measured by a glass electrode method.

[0376] Further, the content of each compounding component in Tables 1 and 2 was all the effective ingredient amount.

[0377] In addition, for each of the antifungal agent compositions for hard surface of Examples 1 to 13 and Comparative Example 5, the viscosity at 25°C was measured by the following method. In Examples 1 to 13, it was a low viscosity liquid of 20 mPa-s or less, and in contrast, Comparative Example 5 was a high viscosity liquid of 180 mPa-s.

[0378] <Viscosity Measurement Method>

[0379] A rotor equipped with a rotor No. 1 was prepared in a B-type viscometer (Model BM) manufactured by TOKIMEC INC, and 100 mL of each of the antifungal agent compositions for hard surface was filled in a beaker for viscosity measurement, and temperature adjustment was performed in a constant temperature water tank at 25°C. The beaker containing the composition was set in the viscometer, the rotor rotation speed was set to 60 r / min, and measurement was performed, and the value after 60 seconds was measured as the viscosity of the antifungal agent composition for hard surface.

[0380] [Evaluation of specific volume of foam on water seal portion]

[0381] In a cubic container (10 cm x 10 cm x 10 cm) imitating a water-filled water seal portion of a flush toilet, the hard surface of Table 1 was filled with the antifungal agent composition in a pressure-accumulating ejection container (TA-F, manufactured by Yoshino Works), and the composition was applied as a foam of 5 g. After the foam was formed, it was left to stand for 30 seconds, 5 minutes, or 10 minutes, and then only the foam was scooped up and put into a conical liquid meter (Model No. 1423, manufactured by PMP, capacity 250 mL, manufactured by Kartell), and the specific volume of the foam after each time was measured. The specific volume of the foam was calculated according to the following formula. The results are shown in Table 1.

[0382] Specific volume of foam (mL / g) = Foam volume (mL) / Ejection amount (g)

[0383] In addition, from the specific volume of the foam after 30 seconds and the specific volume of the foam after 10 minutes, an index of foam stability calculated from the following formula was calculated. The results are shown in Table 1. The closer the value is to 1, the better the foam stability.

[0384] Foam stability = (Specific volume of foam after 10 minutes (mL / g) / Specific volume of foam after 30 seconds (mL / g))

[0385] In addition, in the comparison between the examples and the comparative examples, the influence of viscosity was considered to be one of the reasons for finding the difference in the specific volume of the foam. As shown in the above results, in Examples 1 to 13, all were low-viscosity liquids of 20 mPa-s or less, and in contrast, Comparative Example 5 was a high-viscosity liquid of 180 mPa-s, and thus it was considered that the air-liquid mixing mechanism using the trigger-type container did not function well, and the specific volume of the foam became small.

[0386] [Evaluation of persistence of blackening suppression]

[0387] < Persistence of blackening suppression test (1) >

[0388] As a test object, a household toilet (TOTO NEOREST RH1 (material: ceramic, product number: TCF9768, manufactured by TOTO Co., Ltd., manufactured in 2022), NEW Alauno V (material: organic glass, product number: CH3010W, manufactured by Panasonic Corporation, manufactured in 2016), and the like) that is cleaned once a week was subjected to a test for the persistence of the effect of suppressing the occurrence of blackening caused by mold. The hard-surface antifungal agent composition of Table 1 was filled in a pressure-accumulating spray container (TA-F, manufactured by Yoshino Industry Co., Ltd.), and on the first day of the test, (1) 10 ml of the hard-surface antifungal agent composition was applied as a foam so as to cover the entire inside of the bowl of the toilet, and after 5 minutes, it was washed with the water of the toilet tank. Thereafter, on the seventh day, the operation of (1) was performed. The above operation was performed for one month (4 cycles), and the state of dirt on the inside of the bowl of the toilet one month after the start of the test was visually observed. Furthermore, the test object household toilet was also used on a daily basis during the test period. The residual rate of blackening on the first day of the test was taken as 100%, and the evaluation was performed visually by 5 professional panelists in accordance with the following evaluation criteria, and an average of 3 points or more was taken as a pass. The higher the score, the more excellent the persistence of the suppression of blackening. The results are shown in Table 1. Furthermore, a larger number means a higher effect. Furthermore, it is considered that blackening is generated due to the proliferation of mold, and the more excellent the antifungal property, the higher the average of the evaluation points of the residual evaluation of blackening.

[0389] 5 points: The residual amount of blackening was 0% (completely no blackening) compared to one month ago.

[0390] 4 points: The residual amount of blackening was 1 to 10% (almost no blackening) compared to one month ago.

[0391] 3 points: The residual amount of blackening was 11 to 20% (blackening was not obvious) compared to one month ago.

[0392] 2 points: The residual amount of blackening was 21 to 50% (blackening was slightly obvious) compared to one month ago.

[0393] 1 point: The residual amount of blackening was 51% or more (blackening was obvious) compared to one month ago.
