Summary of the Invention

Problems to be Solved by the Invention

[0006] The metered-dose aerosol product of Patent Document 1 improves the pest control efficiency by enhancing the injection force. However, it cannot necessarily be said that such a metered-dose aerosol product with a strong injection force is a formulation design suitable for use in confined spaces such as bathrooms and toilets.

[0007] The metered-dose aerosol product of Patent Document 2 is said to exhibit a sufficient deodorizing effect not only on the space but also on the floor surface. However, harmful microorganisms such as mold and bacteria are a problem in terms of their generation and propagation on ceilings and walls where cleaning is difficult to reach. Therefore, it is not necessarily suitable for controlling harmful microorganisms in confined spaces such as bathrooms and toilets.

[0008] As described above, various metered-dose aerosol products for insecticidal and deodorizing purposes have been developed. However, the development of metered-dose aerosol products for controlling harmful microorganisms such as mold, bacteria, and viruses, as well as harmful fine substances such as house dust and PM2.5, is considered difficult and has not yet been put into practical use.

[0009] In particular, for controlling harmful microorganisms such as mold in bathrooms, hermetic fumigants and total spray type aerosols have been commonly used. These formulations are said to prevent the generation of harmful microorganisms such as mold for a certain period after use in a single treatment. However, each time, it is necessary to discard the used hermetic fumigants and total spray type aerosols, which is laborious. In addition, if the used area cannot be completely sealed, there is a risk that part of the smoke or chemical agent may leak into other rooms during use. Therefore, the development of a metered-dose aerosol product capable of controlling harmful microorganisms such as mold with a simpler operation than (1) hermetic fumigants and (2) total spray type aerosols is desired.

[0010] The present invention has been made in view of the above problems, and by uniformly adhering a sufficient amount of a control component to the ceiling and walls, it is possible to exhibit an excellent control effect against specific harmful substances including harmful microorganisms and / or harmful fine substances in a space (particularly, a confined space). An object of the present invention is to provide a metered-dose aerosol product for controlling specific harmful substances and a method for controlling specific harmful substances using the same.

[0038] As the organic solvent, which is one of the main components of the aerosol stock solution, for example, lower alcohols having 2 to 3 carbon atoms such as ethanol and isopropanol (IPA), hydrocarbon solvents such as normal paraffin and isoparaffin, higher fatty acid esters having 16 to 20 carbon atoms such as isopropyl myristate (IPM), glycol ether solvents having 3 to 10 carbon atoms, and ketone solvents can be mentioned. Among these, since the injection particles do not remain excessively in the air and a sufficient amount of the control component adheres uniformly to the ceiling and wall surface, and an excellent control effect against specific harmful substances including harmful microorganisms and / or harmful fine substances can be obtained, lower alcohols having 2 to 3 carbon atoms, hydrocarbon solvents, and higher fatty acid esters having 16 to 20 carbon atoms are preferred, and it is more preferred to use lower alcohols having 2 to 3 carbon atoms which have a bactericidal control effect, a virus control effect, etc. The above-mentioned organic solvents can be used alone or in a mixture of multiple types, but from the aspect of simplifying the manufacturing process, it is preferable to use only one type of component as the organic solvent. In addition to the organic solvent, it is also possible to mix an aqueous solvent such as water.

[0039] The specific gravity of the aerosol stock solution at 20°C is set to 0.76 to 0.95, preferably 0.76 to 0.90, and more preferably 0.76 to 0.88. The specific gravity of the aerosol stock solution at 20°C is an important factor related to the sedimentation of the sprayed particles. If the specific gravity of the aerosol stock solution at 20°C is 0.76 to 0.95, in a space (especially a narrow space), a sufficient amount of the control component after spraying can be uniformly attached to the ceiling and wall surfaces. Harmful microorganisms such as mold and bacteria tend to occur and multiply more on ceilings and wall surfaces where cleaning is difficult to reach, and harmful fine substances such as house dust also tend to adhere to the ceiling and wall surfaces. Therefore, with a sufficient amount of the control component uniformly attached to the ceiling and wall surfaces, in a space (especially a narrow space), an excellent control effect can be exerted on specific harmful substances including harmful microorganisms and / or harmful fine substances.

[0040] In the aerosol stock solution, as long as it does not deviate from the gist of the present invention, in addition to the above components, an insecticidal component, a repellent, a fragrance, a deodorant, a stabilizer, an antistatic agent, an antifoaming agent, and an excipient can also be appropriately blended. Examples of the insecticidal component include pyrethroid compounds such as transfluthrin, metofluthrin, profuthrin, terallethrin, flumethrin, empenthrin, monofluorothrin, dimefluthrin, meperfluthrin, heptafluthrin, phenothrin, cyphenothrin, permethrin, cypermethrin, cyfluthrin, bifenthrin, fenpropathrin, tralomethrin, etofenprox, imiprothrin, allethrin, phthalthrin, prallethrin, resmethrin, and natural pyrethrin; silicon compounds such as silafluofen; organophosphorus compounds such as dichlorvos and fenitrothion; carbamate compounds such as propoxur; neonicotinoid compounds such as dinotefuran, imidacloprid, and clothianidin; fipronil, indoxacarb, broflanilide, and methoxadiazone. Examples of the repellent include DEET, ethyl butylacetylaminopropionate (IR3535), p-menthane-3,8-diol, and icariside. Examples of the fragrance include fragrance components such as orange oil, lemon oil, lavender oil, peppermint oil, eucalyptus oil, lemon eucalyptus oil, citronella oil, lime oil, yuzu oil, jasmine oil, hinoki oil, green tea essential oil, perilla oil, menthol, methyl acetate, limonene, α-pinene, linalool, geraniol, phenylethyl alcohol, amyl cinnamic aldehyde, cumin aldehyde, terpineol, and benzyl acetate; and fragrance components containing leaf alcohol or leaf aldehyde called "green fragrance". In addition, when there are optical isomers based on asymmetric carbons or geometric isomers based on double bonds in each component, each of them or any mixture thereof may be used.

[0041] The quantitative spray aerosol product for controlling specific harmful substances of the present invention can also adopt an aqueous formulation. In this case, the amount of water contained in the aerosol stock solution is not particularly limited, but 5 to 80 v / v% is preferred. A small amount of nonionic surfactant may be added as a solubilizing aid within a range that does not affect the spray pattern of the spray particles. Examples of nonionic surfactants include ethers such as polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, and polyoxyethylene alkyl amino ethers; fatty acid esters such as polyethylene glycol fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and polyoxyethylene glycerin fatty acid esters; polyoxyethylene styrenated phenol; and polyalkanolamides of fatty acids, etc.

[0042] <Propellant> The propellant used in the quantitative spray aerosol product for controlling specific harmful substances of the present invention is not particularly limited, and examples include liquefied petroleum gas (LPG) such as propane and butane, normal pentane, isopentane, dimethyl ether (DME), liquefied gases such as hydrofluoroolefins like HFO1234ze, and compressed gases such as nitrogen gas, carbon dioxide gas, nitrous oxide, and compressed air. The above propellants can be used alone or in a mixed state. However, since a sufficient amount of the control component can uniformly adhere to the ceiling and wall surfaces without excessive remaining of the spray particles in the air, and a better control effect can be achieved against specific harmful substances including harmful microorganisms and / or harmful fine substances in a space (especially a narrow space), those containing LPG or hydrofluoroolefin are preferred. In addition, it is preferable to use the propellant with the gauge pressure (20 °C) adjusted to 0.10 to 0.70 MPa.

[0043] The quantitative injection aerosol product for controlling specific harmful substances of the present invention preferably has a volume ratio (a / b) of the aerosol stock solution (a) to the propellant (b) in the aerosol container set to 1 / 99 to 70 / 30 by volume. From the perspective of the adhesion of the chemical agent to the ceiling and wall surfaces, 10 / 90 to 60 / 40 is more preferable, and 20 / 80 to 55 / 45 is even more preferable. If the volume ratio (a / b) is within the above range, in a space (especially a narrow space), when the aerosol is sprayed, the sprayed particles adhere to the ceiling and wall surfaces without excessive remaining in the air, so that a sufficient amount of the specific harmful substance control component can be uniformly adhered to the ceiling and wall surfaces. Thereby, while it is possible to obtain an appropriate control effect against specific harmful substances containing harmful microorganisms and / or harmful fine substances, the irritation to humans can be reduced.

[0044] The quantitative injection aerosol product for controlling specific harmful substances of the present invention has an internal pressure of the aerosol container set to 0.60 MPa or less at 25°C, preferably 0.10 to 0.60 MPa, more preferably 0.20 to 0.60 MPa, and even more preferably 0.30 to 0.50 MPa. If the internal pressure is 0.60 MPa or less at 25°C, in a space (especially a narrow space), when the aerosol is sprayed, a sufficient amount of the specific harmful substance control component can be adhered to the ceiling and wall surfaces. If the internal pressure exceeds 0.60 MPa, the injection momentum is too strong, so when reaching the wall surface, some of the injected particles may bounce back, resulting in insufficient diffusion uniformity of adhesion to the ceiling and wall surfaces. The internal pressure of such an aerosol product can be appropriately adjusted according to the type of the propellant and the vapor pressure of the propellant. The aerosol container only needs to be a pressure-resistant container capable of withstanding an internal pressure of 0.60 MPa, and its materials include, for example, metals such as aluminum and tinplate, synthetic resins such as polyethylene terephthalate, and pressure-resistant glass. Further, when the material of the aerosol container is a synthetic resin, it may be semi-transparent or transparent. In this embodiment, the internal pressure of the aerosol container of the quantitative injection aerosol product for controlling specific harmful substances was measured by the following procedure. (1) Immerse the quantitative injection aerosol product for controlling specific harmful substances in a constant temperature water bath at 25 ± 0.5°C for 30 minutes. (2) Next, place the aerosol product for controlling specific harmful substances in an upright position, airtightly insert the stem of the aerosol container into the insertion port of the pressure gauge, and read the measured pressure to the second decimal place. (3) Conduct the above measurement once, and use the read value as the internal pressure value without rounding the measured value.

[0045] The aerosol product for controlling specific harmful substances of the present invention preferably has an injection force of 2.0 to 40.0 gf, more preferably 2.0 to 35.0 gf, still more preferably 3.0 to 30.0 gf, and particularly preferably 5.0 to 20.0 gf at a position 15 cm away from the injection port. If the injection force is within the above range, when the aerosol is injected in a space (especially a narrow space), a sufficient amount of the specific harmful substance control component will uniformly adhere to the ceiling and wall surfaces, and a practically sufficient control effect against specific harmful substances containing harmful microorganisms and / or harmful fine substances can be obtained. If the injection force is less than 2.0 gf, there is a risk that the injection force is insufficient and the adhesion amount of the specific harmful substance control component to the ceiling and wall surfaces will be insufficient. On the other hand, if the injection force exceeds 40.0 gf, since the injection momentum is too strong, when reaching the wall surface, some of the injection particles may bounce back, resulting in insufficient diffusion uniformity on the ceiling and wall surfaces. Such an injection force can be appropriately adjusted according to the composition of the aerosol stock solution, the type of propellant, the internal pressure of the aerosol product, and the dimensions and shape of the injection port, etc. In this embodiment, the injection force of the aerosol product for controlling specific harmful substances was measured with a digital force gauge (FGC-0.5, manufactured by Nidec-Shimpo Corporation).

[0046] The aerosol product for controlling specific harmful substances of the present invention is provided with a metering injection valve for performing a metering injection treatment in a space. The injection volume per stroke of the metering injection valve is set to 0.08 to 3.0 mL, preferably 0.08 to 2.0 mL, more preferably 0.1 to 1.0 mL, and still more preferably 0.2 to 0.9 mL. If the injection volume per stroke is within the above range, a sufficient amount of the specific harmful substance control component can be uniformly adhered to the ceiling and wall surfaces, and an excellent control effect against specific harmful substances containing harmful microorganisms and / or harmful fine substances can be obtained.

[0047] The injection member (injection button) is a member attached to the aerosol container via a metering injection valve. An injection port is formed in the injection member through which the aerosol stock solution and the propellant taken in from the aerosol container are injected via the stem hole of the metering injection valve. The injection diameter of this injection member is preferably 0.2 to 1.0 mm. If the injection diameter is within the above range, the injection force can be appropriately adjusted within a range. The shape (cross-sectional shape) of the injection port is not particularly limited, and examples include polygons such as circular, square, and elliptical shapes, and a circular shape is preferred. Here, the injection diameter means the major axis of the ellipse when the shape of the injection port is elliptical, and means the diameter of the circumscribed circle of the polygon when the shape of the injection port is polygonal.

[0048] The metering injection aerosol product for controlling specific harmful substances of the present invention has an emission amount of the specific harmful substance control component into the air of 0.01 to 250 mg / m 3 It is preferably set to, and more preferably set to 0.025 to 125 mg / m 3 If the emission amount of the specific harmful substance control component into the air is within the above range, the control effect on specific harmful substances including harmful microorganisms and / or harmful fine substances can be appropriately exerted in the space, and it is possible to surely control specific harmful substances including harmful microorganisms and / or harmful fine substances. The metering injection aerosol product for controlling specific harmful substances of the present invention can set the injection amount of the specific harmful substance control component so that the emission amount of the specific harmful substance control component into the air is 0.01 to 250 mg / m 3 by one injection, or can set the injection amount of the specific harmful substance control component per injection so that the emission amount of the specific harmful substance control component into the air is 0.01 to 250 mg / m 3 by two or more injections. From the viewpoint that a sufficient amount of the specific harmful substance control component can be uniformly adhered to the ceiling and wall surface, and an excellent control effect on specific harmful substances including harmful microorganisms and / or harmful fine substances can be obtained, by two or more injections, the emission amount of the specific harmful substance control component into the air is 0.01 to 250 mg / m 3It is preferably set to be such. The release amount of such a specific harmful substance control component can be implemented by appropriately adjusting the composition of the aerosol stock solution, the volume ratio (a / b) of the aerosol stock solution (a) to the propellant (b), the injection volume per injection of the metering injection valve, etc. within the above-mentioned ranges respectively.

[0049] The metering injection aerosol product for controlling specific harmful substances according to the present invention can usually create an atmosphere capable of controlling specific harmful substances including harmful microorganisms and / or harmful fine substances in a space for approximately 7 to 14 days with one application. By adjusting the composition of the aerosol stock solution, the type of propellant, the specific gravity of the aerosol stock solution at 20°C, the internal pressure of the aerosol container, etc., it is also possible to make the period capable of controlling specific harmful substances including harmful microorganisms and / or harmful fine substances less than 7 days or more than 14 days.

[0050] <Specific harmful substances> The specific harmful substances to be controlled in the present invention include, as harmful microorganisms, organisms or substances derived from organisms such as bacteria, molds, viruses, mites, pollen, etc., and as harmful fine substances, non-organisms or substances derived from non-organisms such as house dust, PM2.5, yellow sand, etc. Harmful microorganisms and harmful fine substances include allergens. The metering injection aerosol product for controlling specific harmful substances of the present invention can more effectively control bacteria and molds that tend to occur and multiply more frequently on ceilings and wall surfaces that are difficult to clean thoroughly among these specific harmful substances.

[0051] 〔Method for controlling specific harmful substances〕 The method for controlling specific harmful substances of the present invention is to use the above-mentioned metering injection aerosol product for controlling specific harmful substances indoors in a space (preferably with a volume of 2.0 to 18.8 m 3It is carried out by spraying toward a narrow space. When the specific harmful substance control method of the present invention is implemented, in a space (particularly a narrow space), a sufficient amount of the control component uniformly adheres to the ceiling and walls, and an excellent control effect is exhibited against specific harmful substances including harmful microorganisms and / or harmful fine substances. Here, the spraying amount of the aerosol product for quantitatively spraying for controlling specific harmful substances is adjusted so that the release amount of the control component for specific harmful substances into the air is 0.01 to 250 mg / m 3 and preferably adjusted to be 0.025 to 125 mg / m 3 and more preferably adjusted to be so. If the release amount of the control component for specific harmful substances is within the above range, an even more excellent control effect can be exhibited against specific harmful substances including harmful microorganisms and / or harmful fine substances.

[0057] In the above Table 1, IPMP represents isopropyl methylphenol, Compound A represents 1,4-bis[3,3´-(1-decylpyridinium)methyloxy]butane dibromide, IPBC represents 3-iodo-2-propyl-N-butylcarbamate, IPA represents isopropanol, IPM represents isopropyl myristate, LPG represents liquefied petroleum gas, and HFO1234ze represents trans-1,3,3,3-tetrafluoropropene. The specific gravity (20 °C) of each component is as follows: IPMP: 0.97, thymol: 0.97, 10% aqueous solution of benzalkonium chloride: 0.98, tebuconazole: 1.25, monocaprylin: 0.99, monocaprylin: 0.99, IPBC: 1.61, ethanol: 0.79, IPA: 0.79, neothiazole: 0.76, IPM: 0.86, hexyl laurate: 0.86.

[0058] For Examples 1 to 16 and Comparative Examples 1 to 3, (1) tests were conducted to evaluate the ceiling and wall adhesion and diffusion uniformity of specific harmful substance control components. The test results are shown in Table 2.

[0059] (1) Ceiling and wall adhesion and diffusion uniformity of specific harmful substance control components Closed volume of 4.2 m 3Six locations on the floor, two locations on the ceiling, and four locations on the wall of a small room (width 1.8 m, depth 1.3 m, height 1.8 m) were installed with glass plates of 20 cm × 20 cm. Standing at one of the four corners of the small room, the test aerosol product was sprayed twice obliquely upward slightly towards the center of the space from a height of 1 m above the floor. Twenty minutes after the spraying, the glass plates installed on the floor, the glass plates installed on the ceiling, and the glass plates installed on the wall were taken out respectively, and the attached specific harmful substance control components were washed out with acetone and analyzed by gas chromatography. Based on the obtained analysis values, the ratio of the amount of control components attached to the ceiling and wall to the amount of control components attached to the floor by 20 minutes after the spraying treatment was determined to evaluate the ceiling-wall adhesion. Regarding the evaluation results, they were shown in three levels of A, B, and C in order from those with good ceiling-wall adhesion. Also, the diffusion uniformity was evaluated from the amount of control components attached to the ceiling and wall respectively. Regarding the evaluation results, they were shown in three levels of A, B, and C in order from those with good diffusion uniformity.

[0061] As a result of the test, in the quantitative spray aerosol products for controlling specific harmful substances of Examples 1 to 16, the ceiling-wall adhesion of the specific harmful substance control components was good. Among them, Examples 1, 3 to 10, 12 to 15 with a specific gravity of 0.76 to 0.88 at 20°C were excellent not only in the ceiling-wall adhesion of the specific harmful substance control components but also in the diffusion uniformity. From this, according to the quantitative spray aerosol product for controlling specific harmful substances of the present invention, the control effect on specific harmful substances including harmful microorganisms and / or harmful fine substances in the space was confirmed.

[0062] On the other hand, in the pump-type spray product of Comparative Example 1 and the metered spray aerosol product of Comparative Example 3 with a specific gravity at 20 °C of the aerosol stock solution exceeding 0.95, the adhesion of the control component to the ceiling and wall surfaces was low. From this, it is considered that in the pump-type spray product of Comparative Example 1 and the metered spray aerosol product of Comparative Example 3, the control effect against specific harmful substances including harmful microorganisms and / or harmful fine substances in the space is not sufficient.

[0063] The metered spray aerosol product of Comparative Example 2 with an internal pressure exceeding 0.60 MPa at 25 °C was insufficient in terms of the diffusion uniformity on the ceiling and wall surfaces.
