Description

Technical Field

[0001] The present invention relates to a mildew-proofing agent composition for preventing the generation of mildew, a mildew-proofing spray product and a mildew-proofing method. Background Art

[0002] In recent years, homes have become airtight and moisture accumulates indoors, making it easy for mold to grow. Mold grows in places where moisture, moderate temperatures, and nutrients are present. In general homes, curtains, wallpapers, and closets near windows where condensation is easy to form, and mattresses where sweat easily seeps in during sleep are places that mold likes. Therefore, measures are needed to prevent mold from growing in these places.

[0003] As a method for preventing the generation of mold, a mold inhibitor is generally applied to an object. As conventional mold inhibitors, for example, those using silver (for example, see Patent Document 1) and those using a photocatalyst (for example, see Patent Document 2) are known. These mold inhibitors are inorganic mold inhibitors. On the other hand, organic mold inhibitors are also known, for example, there is a case where triazole compounds are used as mold inhibitors for wood (for example, see Patent Document 3).

[0009] Problem that the invention aims to solve

[0010] The inorganic mildew-proofing agents represented by Patent Document 1 or Patent Document 2 have the disadvantage of being easily discolored. Therefore, they are not suitable for household items such as curtains, wallpapers, and mattresses. Although the organic mildew-proofing agents represented by Patent Document 3 have less discoloration problems, there is still room for improvement in terms of effectiveness.

[0011] Therefore, the present inventors have focused on organic mildew-proof agents that are highly compatible with household products and have attempted to establish a new mildew-proofing technology. That is, the present invention aims to provide a mildew-proofing agent composition that can exert a mildew-proofing effect that is superior to that of conventional organic mildew-proofing agents. Furthermore, the present invention aims to provide a mildew-proofing spray product that is easy to use by using the mildew-proofing agent composition. Furthermore, the present invention aims to provide a mildew-proofing method using the mildew-proofing spray product.

[0012] Solutions for solving problems

[0013] The antifungal composition of the present invention for solving the above-mentioned problems is characterized in that:

[0014] A mildew-proofing agent composition comprises a triazole compound, glycol, and alcohol.

[0015] The present inventors have newly found that when a diol and a triazole compound are used together, the antifungal property of the triazole compound is enhanced by the diol, and when an alcohol is used together, the triazole compound is appropriately dispersed. Therefore, the antifungal agent composition according to this constitution can exert a more excellent antifungal effect than the case where the triazole compound is used alone.

[0016] In the antifungal composition according to the present invention,

[0017] Preferably, the triazole compound is tebuconazole.

[0018] The antifungal composition according to this configuration can exhibit an excellent antifungal effect by using tebuconazole as a preferred triazole compound.

[0019] In the antifungal composition according to the present invention,

[0020] Preferably, the diol is propylene glycol and / or 1,3-butylene glycol.

[0021] According to the fungicide composition of this configuration, propylene glycol and / or 1,3-butylene glycol are used as preferred diols, so that the effect of enhancing the fungicide property of the triazole compound is particularly excellent.

[0022] In the antifungal composition according to the present invention,

[0023] Preferably, the alcohol is ethanol and / or 2-propanol.

[0024] According to the fungicide composition of this configuration, ethanol and / or 2-propanol are used as the preferred alcohol, so that the dispersibility of the triazole compound is particularly excellent.

[0025] In the antifungal composition according to the present invention,

[0026] The mixing ratio (weight ratio) of the triazole compound to the diol is preferably 1:10 to 1:0.5.

[0027] According to the fungicide composition of this configuration, since the mixing ratio (weight ratio) of the triazole compound and the diol is set to an appropriate range, the fungicide property of the triazole compound can be effectively enhanced by the diol.

[0028] In the antifungal composition according to the present invention,

[0029] Preferably, a deodorizing component is further contained.

[0030] The antifungal composition according to this constitution also contains a deodorizing component, and thus can suppress the generation of unpleasant odors in a humid environment favored by molds.

[0031] In the antifungal composition according to the present invention,

[0032] Preferably, at least one mold selected from the group consisting of Cladosporium sp., Alternaria sp., Fusarium sp., Penicillium sp., Aspergillus sp., Eurotium sp., and Wallemia sp. is used as the target.

[0033] The antifungal composition according to this constitution can prevent the generation of Cladosporium, Alternaria, Fusarium, Penicillium, Aspergillus, Eurotium and Arthrostomyces, which are easily generated in daily living spaces, and thus can obtain a high antifungal effect in daily use. In addition, since the above-mentioned molds are dark to dark colors, by using the antifungal composition of this constitution to impart antifungal properties to fiber products or paper products, consumers can be given an excellent feeling of use.

[0034] In the antifungal composition according to the present invention,

[0035] Preferably used for curtains.

[0036] The antifungal composition according to this constitution can effectively inhibit the growth of mold on curtains, which has been a particular problem in the past.

[0037] The anti-mold spray product according to the present invention for solving the above-mentioned problems is characterized in that:

[0038] A mildew-proof spray product, which is prepared by sealing a spray container with a drug comprising any one of the mildew-proof agent compositions described above and water.

[0039] The content of the alcohol in the drug is set to 20 to 60% by weight.

[0040] According to the anti-mold spray product of this structure, since it contains the anti-mold composition of the present invention, the anti-mold property of the triazole compound is enhanced by the diol, and the triazole compound is appropriately dispersed by the alcohol, so that a more excellent anti-mold product can be made than before. In addition, since the alcohol content in the agent sealed in the spray container is set to 20 to 60% by weight, the triazole compound will not precipitate but will be completely dissolved in the agent, resulting in that the accurate amount of the agent can be given to the treatment object corresponding to the number of sprays. Furthermore, if it is the above-mentioned alcohol content, since an appropriate spray pattern is formed, the agent can be attached to the treatment object everywhere.

[0041] The anti-mold method according to the present invention for solving the above-mentioned problems is characterized in that:

[0042] A method for preventing mildew comprises spraying the above-mentioned agent from the above-mentioned spray product for preventing mildew onto a treatment object, so that the above-mentioned agent adheres to at least a part of the surface of the above-mentioned treatment object.

[0043] According to the anti-mold method of this configuration, the anti-mold spray product of the present invention is used to attach the agent to at least a portion of the surface of the treatment object, so that the treatment object is subjected to anti-mold treatment, thereby effectively preventing the generation of mold. DETAILED DESCRIPTION

[0044] Hereinafter, the antifungal composition, antifungal spray product, and antifungal method of the present invention will be described. However, the present invention is not intended to be limited to the embodiments described below.

[0045] The present inventors have newly discovered that when a triazole compound that has been used as a wood mildew preventer is used as a general household mildew preventer, if a diol is used in combination with the triazole compound, the mildew resistance of the triazole compound is enhanced, and if an alcohol is used in combination, the triazole compound is appropriately dispersed, and a new mildew preventer composition is conceived based on this understanding. The details are described in the embodiments described below. The mildew preventer composition of the present invention is sealed in a spray container together with water to form a mildew preventer spray product of the present invention. If it is applied to a curtain of a fiber product, an excellent mildew preventer effect is confirmed. It should be noted that in this specification, the so-called mildew preventer effect means mainly preventing the generation of mildew before it occurs, and eliminating the generated mildew and inhibiting the expansion of the generated mildew are also included in the mildew preventer effect. As the types of molds that can be inhibited from growing by the mold-proof composition (mold-proof spray product) of the present invention, for example, there can be mentioned: Cladosporium (so-called Aspergillus niger), Alternaria, Fusarium, Penicillium, Aspergillus, Eurotium, Arthrobasidiomyces, etc. These molds are molds that are easily produced in daily living spaces such as dormitories, living rooms, bathrooms, toilets, and kitchens. Because their appearance is dark to dark, if the mold-proof composition of the present invention is used to give mold-proof properties to fiber products (such as curtains) or paper products (such as wallpaper) present in the above living spaces, the coloring caused by molds is prevented or greatly improved, and consumers can be given an excellent feeling of use. In particular, if the product of the present invention is applied to curtains set in dormitories and living rooms, consumers can get a sense of cleanliness and peace of mind.

[0046] <Anti-mold composition>

[0047] The antifungal composition of the present invention contains a triazole compound, a diol, and an alcohol as main components.

[0048] As triazole compounds, there can be mentioned: tebuconazole, imibenconazole-db, triadimenol, paclobutrazol, propiconazole, hexaconazole, penconazole, myclobutanil, metconazole (registered trademark), etc. Among these compounds, tebuconazole is preferred. It should be noted that these triazole compounds can be used alone or in combination.

[0049] Examples of the diol include ethylene glycol, propylene glycol, 1,3-butanediol, pentanediol, 1,2-hexanediol, etc. Among these compounds, propylene glycol and 1,3-butanediol are preferred. It should be noted that these diols may be used alone or in combination of two or more.

[0050] Examples of the alcohol include methanol, ethanol, 1-propanol, 2-propanol, butanol, pentanol, hexanol, etc. Among these compounds, ethanol and 2-propanol are preferred. It should be noted that these alcohols may be used alone or in combination of two or more.

[0051] The antifungal composition of the present invention may contain, in addition to the above-mentioned triazole compounds, diols and alcohols, a deodorant component, a fragrance, a pH adjuster, etc. For example, if flavonoids are contained as deodorant components, it is possible to suppress the unpleasant odor that is generated in a humid environment that molds like.

[0052] The antifungal composition of the present invention is prepared by mixing the above-listed components at an appropriate weight ratio, and further adding water to adjust the concentration of each component to an appropriate level.

[0053] When the above-listed components are mixed, the mixing ratio (weight ratio) of the triazole compound to the diol is preferably adjusted to 1:10 to 1:0.5, and more preferably adjusted to 1:10 to 1:1. When the mixing ratio of the triazole compound to the diol is less than 1:10 (i.e., the mixing amount of the triazole compound relative to the mixing amount of the diol is less than 1 / 10), there is a concern that the antifungal effect cannot be fully exerted due to insufficient triazole compound. When the mixing ratio of the triazole compound to the diol exceeds 1:0.5 (i.e., the mixing amount of the triazole compound relative to the mixing amount of the diol is more than 2 times), there is a concern that the antifungal property of the triazole compound cannot be fully enhanced due to insufficient diol.

[0054] When water is added, the content of alcohol in the prepared agent (a mixture of a triazole compound, a diol, an alcohol and water, and containing other components as needed) is set to 20 to 60% by weight. If it is within this range, the triazole compound can be completely dissolved in the agent without precipitation. Therefore, it is easy to give an accurate amount of the agent to the treatment object. In addition, when forming the anti-mildew spray product described later, since an appropriate spray pattern is formed, the agent can be attached to the treatment object everywhere.

[0055] <Spray products for antifungal agents>

[0056] The preferred product form of the antifungal composition of the present invention is a spray product. For example, the antifungal spray product of the present invention is formed by enclosing the above-mentioned agent (at least a mixture of the antifungal composition of the present invention and water) in a spray container. As the spray container, a spray container with a trigger-type sprayer is preferably used. The agent enclosed in the spray container is as described above, and the alcohol content in the agent is set to 20 to 60% by weight. Accordingly, the agent diffuses into a roughly circular shape during spraying, and a spray pattern in which the amount of the agent applied to the treatment object becomes roughly uniform can be formed. Moreover, an accurate amount of the agent can be applied to the treatment object corresponding to the number of sprays.

[0057] <Anti-mold method>

[0058] The anti-mildew method of the present invention can be implemented using the above-mentioned anti-mildew spray product. Specifically, the operator holds the trigger of the anti-mildew spray product and sprays the agent toward the surface of the treatment object. Accordingly, the agent adheres to the surface of the treatment object. Furthermore, the agent is dried as needed. The spraying and drying of the agent can also be repeated multiple times. The spray amount of the agent is preferably 9.0 to 13.5 g / m2 relative to the treatment object. When the spray amount of the agent is less than 9.0 g / m2, the adhesion amount of the triazole compound and diol as the active ingredients is insufficient, and there is a case where the anti-mildew effect cannot be fully imparted due to the raw materials of the treatment object. The spray amount of the agent exceeds 13.5 g / m 2 In the case of drying, the treated object still has a sticky feeling. If a series of mildew-proofing treatments for the treated object are completed, an excellent mildew-proofing effect is exerted on the treated object, and the generation of mold can be effectively prevented for a long time.

[0088] <Appearance of the drug solution>

[0089] The appearance of each of the drug solutions of Examples 1 to 7 and Comparative Examples 1 to 3 was visually confirmed. The evaluation criteria of the appearance are as follows.

[0090] ○: No precipitation was observed in the drug solution, and the drug solution was colorless and transparent.

[0091] ×: Precipitation was observed in the drug solution, and it was turbid.

[0092] <Anti-mold effect>

[0093] Glucose peptone medium as a mold culture medium was sprayed onto a lace curtain (spray area: 10 cm×10 cm) and air-dried for 1 hour. The antifungal spray product of the present invention containing the drug solution of Examples 1 to 7 was sprayed onto the dried lace curtain (spray amount: 9.9 to 11.1 g / m 2 ) and air-dried for 1 hour. The same operation was performed on the spray products sealed with the liquid medicines of Comparative Examples 1 to 3. Next, a certain number of molds (Closporium (Aspergillus niger), Penicillium) were attached to the lace curtains, and then water was sprayed with a sprayer, and the lace curtains were stored in a desiccator maintained at a humidity of 90% to cultivate the mold. Then, the mold generation status after 1 week was confirmed. The evaluation criteria for the mold generation status are as follows.

[0094] ◎: No mold is generated.

[0095] ○: Mold was slightly generated, but there was no problem in appearance.

[0096] △: Some mold generation was observed.

[0097] ×: Mold generation was clearly observed.

[0098] <Spray pattern>

[0099] The antifungal spray products of the present invention encapsulating the chemical solutions of Examples 1 to 7 and the spray products encapsulating the chemical solutions of Comparative Examples 1 to 3 were sprayed once toward a plastic plate at a distance of 20 cm, and the shape of the spray pattern formed on the plastic plate was visually confirmed, and the size was measured using a scale. The evaluation criteria for the shape of the spray pattern are as follows.

[0104] [Table 1]

[0105]

[0106] Regarding the spray products for antifungal agents using the liquid medicines of Examples 1 to 7, the appearance of the liquid medicines was that no precipitation was observed in the liquid medicines, and the liquid medicines remained colorless and transparent, and no problems were found. The antifungal effect was that although mold was slightly generated, it was not a problem in practical use. In particular, regarding Examples 1 to 4, mold was not generated at all, confirming an excellent antifungal effect. It is suggested that setting the ethanol content in the agent to 20 to 60% by weight is particularly effective. Regarding the spray pattern, although the spray pattern shapes of Examples 6 and 7 were slightly uneven, they were good overall.

[0107] In contrast, the spray products using the chemical solutions of Comparative Examples 1 to 3 could not achieve both the appearance of the chemical solution and the antifungal effect, and were inferior in performance and use to Examples 1 to 7 (the products of the present invention).
