Disclosure of Invention
Problems to be solved by the invention
The quantitative spray aerosol product of patent document 1 is a product that improves pest control efficiency by increasing the spray force, but such a quantitative spray aerosol product having a strong spray force is not necessarily a formulation design suitable for use in a narrow space such as a bathroom or a toilet.
The quantitative aerosol spray product of patent document 2 exhibits a sufficient deodorizing effect not only on spaces but also on floors, but is not necessarily a product suitable for controlling harmful microorganisms in a narrow space such as a bathroom or a toilet because it causes problems such as generation or propagation of harmful microorganisms such as mold and bacteria in ceilings and walls where cleaning is difficult.
As described above, various kinds of quantitative spray aerosol products have been developed for the purpose of insect disinfestation, deodorization, and the like, but the development of quantitative spray aerosol products in which harmful microorganisms such as mold, bacteria, viruses, and the like, and harmful fine substances such as indoor dust, PM2.5, and the like are targeted for control has been difficult, and has not been put to practical use.
In particular, in the control of harmful microorganisms such as mold in a bathroom, it has been common to use (1) a fumigant or (2) a total amount of an aerosol. These preparations prevent the generation of harmful microorganisms such as mold at a certain period after use by one treatment, but each time, the used fumigant or the full-spray aerosol must be discarded, which takes labor and time. If the place of use is not completely sealed, there is a concern that smoke or a part of the medicine leaks into another room during use. Accordingly, it is desired to develop a quantitative spray aerosol product capable of controlling harmful microorganisms such as mold by a simpler operation than (1) fumigant or (2) total spray aerosol.
The present invention has been made in view of the above problems, and an object thereof is to provide: by uniformly adhering a sufficient amount of a control component to a ceiling or a wall, a quantitative spray aerosol product for controlling a specific pest, which exhibits an excellent control effect on a specific pest including a harmful microorganism and/or a harmful fine substance, in a space (particularly a small space); a specific pest control method using the product.

Detailed Description
Hereinafter, the quantitative injection aerosol product for controlling specific pests and the specific pest control method according to the present invention will be described. However, the present invention is not intended to be limited to the configurations described below.
[ Quantitative spray aerosol product for controlling specific pests ]
The quantitative spray aerosol product for preventing and controlling specific harmful substances of the present invention is a quantitative spray aerosol for preventing and controlling specific harmful substances including harmful microorganisms and/or harmful fine substances in a space (particularly a small space), which is formed by filling an aerosol container provided with a quantitative spray valve with an aerosol collagen liquid containing a specific harmful substance preventing and controlling component and a solvent and a spray agent. The term "harmful microorganism" as used herein refers to a biological or biologically derived substance such as bacteria, mold, virus, mites, and pollen, and the term "harmful fine substance" refers to an abiotic or abiotic-derived substance such as house dust, PM2.5, yellow sand, and the like. In this specification, the term "harmful microorganism" and "harmful fine substance" are collectively referred to as "specific harmful substance". The "space" of the present invention includes, but is not particularly limited to, a gap space of less than 2.0m 3, a narrow space of the order of 2.0 to 18.8m 3, an indoor space of the order of 18.8 to 33.3m 3 (area 7.5 to 13.3m 2, height 2.2 to 3.0 m) corresponding to a room of 4.5 to 8 tatami, and a wide indoor space of the order of 33.3 to 66.6m 3 (area 13.3 to 26.6m 2, height 2.2 to 3.0 m) corresponding to a room of 8 to 16 tatami. The "small space" in which the quantitative spray aerosol product for controlling a specific pest of the present invention exhibits particularly excellent effects is assumed to be a space having a volume of about 2.0 to 18.8m 3, and examples thereof include closed or semi-closed spaces such as bathrooms, dressing rooms, toilets, closets, cupboards, automobiles, tents, warehouses, storehouses, garages, and hallways. More specifically, for example, a toilet or the like is used as a small space having a volume of 2.0 to 3.0m 3, and a bathroom or the like is used as a small space having a volume of 3.0 to 18.8m 3. The quantitative spray aerosol product for controlling specific pests of the present invention is a quantitative spray aerosol, and therefore the spray amount of the chemical is small, and further, by properly setting the specific gravity of the aerosol stock solution at 20 ℃ and the internal pressure of the aerosol container at 25 ℃, an excellent control effect on specific pests including harmful microorganisms and/or harmful fine substances in a space (particularly, a narrow space) is achieved. In the present specification, the harmful microorganisms are killed in addition to the effect of preventing the growth of harmful microorganisms by forming an environment where the growth of harmful microorganisms is difficult or existing, and thus the effect of preventing the growth is called a control effect together with the effect of preventing the growth. For example, when a mold is a control object, the mold-preventing effect and the mold-killing effect are included in the control effect. In addition, the harmful fine material is called a control effect together with the effect of preventing pollution because it is difficult for the harmful fine material to adhere to the environment such as a wall and the harmful fine material that has adhered to the wall is removed. For example, when the indoor dust is a control object, the dust-proof effect and the dust-removing effect are included in the control effect.

The content of the specific pest control ingredient in the aerosol-type collagen liquid is preferably 0.01 to 70w/v%, more preferably 0.05 to 50w/v%, still more preferably 0.1 to 40w/v%. When the content of the specific pest control ingredient in the aerosol stock solution is in the range of 0.01 to 70w/v%, a sufficient amount of the pest control ingredient is uniformly adhered to the ceiling and the wall surface when the aerosol is sprayed in a space (particularly, a small space), and therefore, an appropriate pest control effect on the specific pest including the pest microorganism and/or the pest fine substance can be obtained.
Examples of the organic solvent that is one of the main components of the aerosol collagen liquid include: lower alcohols having 2 to 3 carbon atoms such as ethanol and isopropyl alcohol (IPA), hydrocarbon solvents such as normal paraffins and isoparaffins, higher fatty acid esters having 16 to 20 carbon atoms such as isopropyl myristate (IPM), glycol ether solvents having 3 to 10 carbon atoms, ketone solvents, and the like. Among these, in order to obtain an excellent control effect on specific pests including harmful microorganisms and/or harmful fine substances by uniformly adhering a sufficient amount of a control component to the ceiling and wall surfaces without excessively leaving the particles in the air, a lower alcohol having 2 to 3 carbon atoms, a hydrocarbon solvent, and a higher fatty acid ester having 16 to 20 carbon atoms are preferable, and a lower alcohol having 2 to 3 carbon atoms, which also has a bacterial control effect, a virus control effect, and the like, is more preferable. The organic solvent may be used alone or in a mixture of a plurality of types, but from the viewpoint of simplifying the production process, it is preferable to use only one type of component. In addition, an aqueous solvent such as water may be mixed in addition to the organic solvent.
The specific gravity of the aerosol stock solution at 20 ℃ is set to 0.76 to 0.95, preferably 0.76 to 0.90, more preferably 0.76 to 0.88. The specific gravity of the aerosol stock solution at 20 ℃ is an important factor related to sedimentation of the sprayed particles, and if the specific gravity of the aerosol stock solution at 20 ℃ is 0.76 to 0.95, a sufficient amount of the control component after spraying can be uniformly adhered to the ceiling and wall surface in a space (particularly, a narrow space). Harmful microorganisms such as mold and bacteria tend to be generated and propagated in large amounts in ceilings, walls, and the like where cleaning is difficult, and even in the case of harmful fine substances such as house dust, the harmful fine substances tend to adhere to ceilings and walls, and thus, by means of a sufficient amount of the control component adhering uniformly to ceilings and walls, excellent control effects can be exerted on specific harmful substances including harmful microorganisms and/or harmful fine substances in a space (particularly, a narrow space).
In addition to the above components, the aerosol collagen liquid may be appropriately blended with an insecticidal component, a repellent, a fragrance, a deodorant, a stabilizer, an antistatic agent, an antifoaming agent, an excipient, and the like, as long as the gist of the present invention is not impaired.

Examples of the fragrance include: aromatic components such as orange oil, lemon oil, lavender oil, peppermint oil, eucalyptus oil, citronella oil, lyme oil, grapefruit oil, jasmine oil, juniper oil, green tea essential oil, peppermint oil, menthol, menthyl acetate, limonene, α -pinene, linalool, geraniol, phenylethyl alcohol, amyl cinnamaldehyde, cumyl aldehyde, terpineol, and benzyl acetate, and perfume components containing green leaf alcohol or green leaf aldehyde called "green fragrance" are blended. In the case where an asymmetric carbon-based optical isomer or a double bond-based geometric isomer of each component exists, each of them may be used or any mixture thereof may be used.
The quantitative injection aerosol product for controlling specific harmful substances of the present invention may be formulated as an aqueous formulation. In this case, the amount of water contained in the aerosol stock solution is not particularly limited, but is preferably 5 to 80v/v%, and 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 the nonionic surfactant include: polyoxyethylene alkyl ethers, polyoxyethylene alkylphenyl ethers, polyoxyethylene polyoxypropylene alkyl ethers, and ethers such as polyoxyethylene alkyl amino ethers, polyethylene glycol fatty acid esters, polyoxyethylene sorbitan fatty acid esters, and fatty acid esters such as polyoxyethylene glycerin fatty acid esters, polyoxyethylene styrenated phenols, and polyalkylene alkanolamides of fatty acids.
< Propellant >)
The propellant used in the quantitative spray aerosol product for controlling a specific pest of the present invention is not particularly limited, but examples thereof include: liquefied Petroleum Gas (LPG) such as propane and butane, liquefied gas such as hydrofluoroolefins such as n-pentane, isopentane, dimethyl ether (DME) and HFO1234ze, and other gases such as nitrogen, carbonic acid gas, nitrous oxide and compressed air. The propellant may be used alone or in a mixed state, but is preferably composed of LPG or hydrofluoroolefins because a sufficient amount of a control component is uniformly adhered to the ceiling and wall surface so that the particles are not excessively left in the air, and a more excellent control effect can be exerted on specific pests including harmful microorganisms and/or harmful fine substances in a space (particularly a narrow space). The propellant is preferably used by adjusting the gauge pressure (20 ℃) to 0.10 to 0.70 MPa.
In the quantitative spray aerosol product for controlling a specific pest of the present invention, the volume ratio (a/b) of the aerosol-forming liquid (a) to the propellant (b) in the aerosol container is preferably set to 1/99 to 70/30 by volume, more preferably 10/90 to 60/40, still more preferably 20/80 to 55/45 from the viewpoint of adhesion of the chemical to the ceiling and wall surfaces. When the volume ratio (a/b) is within the above range, the particles to be sprayed are not excessively left in the air and adhere to the ceiling and wall surface when the aerosol is sprayed in the space (particularly, a small space), and therefore a sufficient amount of the specific pest control ingredient can be uniformly adhered to the ceiling and wall surface. Thus, the effect of preventing and removing specific harmful substances including harmful microorganisms and/or harmful fine substances can be obtained properly, and the feeling of irritation to the human can be reduced.
The internal pressure of the aerosol container of the quantitative injection aerosol product for controlling specific pests according to the present invention is set to 0.60MPa or less, preferably 0.10 to 0.60MPa, more preferably 0.20 to 0.60MPa, and even more preferably 0.30 to 0.50MPa at 25 ℃. When the internal pressure is 0.60MPa or less at 25 ℃, a sufficient amount of the specific pest control ingredient can be adhered to the ceiling or wall surface when the aerosol is sprayed in a space (particularly, a narrow space). If the internal pressure exceeds 0.60MPa, the force of the jet is too strong, so that when the jet reaches the wall surface, a part of the jet particles rebound, and there is a possibility that the uniformity of diffusion of adhesion to the ceiling or the wall surface becomes insufficient. The internal pressure of such an aerosol product can be appropriately adjusted by the type of propellant, the vapor pressure of the propellant, and the like. The aerosol container may be a pressure-resistant container capable of withstanding an internal pressure of 0.60MPa, and examples of the material thereof include metals such as aluminum and tin plating, synthetic resins such as polyethylene terephthalate, pressure-resistant glass, and the like. In addition, when the aerosol container is made of synthetic resin, it may be translucent or transparent. In the present embodiment, the internal pressure of the aerosol container of the quantitative injection aerosol product for controlling a specific pest is measured by the following procedure.
(1) A quantitative spray aerosol product for controlling specific harmful substances was immersed in a constant temperature water tank at 25.+ -. 0.5 ℃ for 30 minutes.
(2) Next, the quantitative spray aerosol product for specific pest control was set in an upright state, and a stem of an aerosol container was air-tightly inserted into an insertion port of a pressure gauge, and the measured pressure was read to the 2 nd decimal place.
(3) The above measurement was performed 1 time, and the read value was set as the internal pressure value, instead of rounding the measured value.
In the quantitative spray aerosol product for controlling a specific pest of the present invention, the spray force is preferably 2.0 to 40.0gf, more preferably 2.0 to 35.0gf, even more preferably 3.0 to 30.0gf, and particularly preferably 5.0 to 20.0gf at a distance of 15cm from the spray opening. When the spraying force is in the above range, a sufficient amount of the specific pest control ingredient uniformly adheres to the ceiling and the wall surface when spraying the aerosol in the space (particularly, a small space), and a practically sufficient control effect on the specific pest including the harmful microorganism and/or the harmful fine substance is obtained. If the spraying force is less than 2.0gf, the spraying force may be insufficient, and the adhesion amount of the specific pest control ingredient to the ceiling or wall surface may be insufficient, whereas if the spraying force exceeds 40.0gf, the spraying force is too strong, and therefore when the wall surface is reached, a part of the sprayed particles rebound, and there is a possibility that the uniformity of diffusion at the ceiling or wall surface becomes insufficient. Such ejection force can be appropriately adjusted by the composition of the aerosol liquid, the type of the ejection agent, the internal pressure of the aerosol product, the size and shape of the ejection orifice, and the like. In the present embodiment, the injection force of the quantitative injection aerosol product for controlling specific pests was measured by a digital dynamometer (FGC-0.5, manufactured by japan electric power generation and new co).
The quantitative injection aerosol product for preventing and eliminating specific harmful matters is provided with a quantitative injection valve for performing quantitative injection treatment in a space. The injection capacity of the quantitative injection valve is set to 0.08 to 3.0mL, preferably 0.08 to 2.0mL, more preferably 0.1 to 1.0mL, and even more preferably 0.2 to 0.9mL. When the spraying capacity per time is within the above range, a sufficient amount of the specific pest control ingredient can be uniformly adhered to the ceiling and wall surface, and an excellent pest control effect on the specific pest including the harmful microorganism and/or the harmful fine substance can be obtained.
The ejection member (ejection button) is a member attached to the aerosol container via a metering jet valve. An injection port that injects aerosol stock solution and an injection agent obtained from an aerosol container through a stem hole of a metering injection valve is formed on the injection member. The ejection orifice diameter of the ejection member is preferably 0.2 to 1.0mm. If the injection port diameter is in the above range, the injection force can be adjusted to an appropriate range. The shape (cross-sectional shape) of the ejection opening is not particularly limited, but a polygon such as a circle or a quadrangle, an ellipse, or the like is exemplified, and a circle is preferable. Here, the jet port diameter refers to the major diameter of an ellipse when the jet port is elliptical in shape, and refers to the diameter of a circumscribed circle of a polygon when the jet port is polygonal in shape.
In the quantitative injection aerosol product for controlling specific pests according to the present invention, the release amount of the specific pest control ingredient to the air is preferably set to 0.01 to 250mg/m 3, more preferably set to 0.025 to 125mg/m 3. When the amount of the specific pest control ingredient released into the air is within the above range, the effect of controlling the specific pest including the harmful microorganism and/or the harmful fine substance is properly exhibited in the space, and the specific pest including the harmful microorganism and/or the harmful fine substance can be reliably controlled. The quantitative injection aerosol product for controlling a specific pest of the present invention may be configured such that the amount of the specific pest control ingredient released into the air is 0.01 to 250mg/m 3 by 1 injection, or the amount of the specific pest control ingredient released into the air may be set such that the amount of the specific pest control ingredient released into the air is 0.01 to 250mg/m 3 by 2 or more injections. In view of obtaining an excellent control effect on a specific pest including a pest microorganism and/or a pest fine substance by uniformly adhering a sufficient amount of the specific pest control ingredient to a ceiling or a wall surface, the amount of the specific pest control ingredient released into the air is preferably set to 0.01 to 250mg/m 3 by 2 or more injections. The amount of the specific pest control ingredient released can be appropriately adjusted in the above-described ranges by 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 of each of the quantitative injection valves, and the like.
The quantitative spray aerosol product for controlling a specific pest according to the present invention can make a space an environment capable of controlling a specific pest including a harmful microorganism and/or a harmful fine substance in about 7 to 14 days, usually by 1 application. The period in which a specific pest including a harmful microorganism and/or a harmful fine substance can be controlled may be set to be less than 7 days or more than 14 days by adjusting the composition of the aerosol collagen liquid, the type of the propellant, the specific gravity of the aerosol stock solution at 20 ℃, the internal pressure of the aerosol container, and the like.

The aerosol collagen liquid was placed in a container having a pump type spray head with a spray capacity of 0.2mL for 1 time, to obtain a pump type spray product of comparative example 1. The amount of the control component sprayed per one spray of the pump spray product was 30mg. The ejection force at the ejection distance of 15cm was 2.0gf.
Examples 2 to 16 and comparative examples 2 to 3
By following the procedure of example 1, various aerosol articles shown in table 1 were prepared. The specific quantitative spray aerosol product for pest control of example 8 was an aerosol container with a 1-time spray valve having a spray capacity of 0.2mL, and the specific quantitative spray aerosol products for pest control of examples 1,3, 4, 6, 9, 11 to 13 and 16 and the comparative examples 2 to 3 were aerosol containers with a 1-time spray valve having a spray capacity of 0.4mL, and the specific quantitative spray aerosol products for pest control of examples 2,5, 7, 10, 14 and 15 were aerosol containers with a 1-time spray valve having a spray capacity of 1.0 mL.
TABLE 1
In Table 1 above, IPMP represents isopropyl methylphenol, compound A represents 1, 4-bis [3,3' - (1-decylpyridinium) methoxy ] dibromobutane, IPBC represents 3-iodo-2-propyl-N-butylcarbamate, IPA represents isopropyl alcohol, IPM represents isopropyl myristate, LPG represents liquefied petroleum gas, HFO1234ze represents trans-1, 3-tetrafluoropropane. The specific gravity (20 ℃) of each component was IPMP:0.97, thymol: 0.97, benzalkonium chloride 10% aqueous solution: 0.98, tebuconazole: 1.25, glycerol monocaprylate: 0.99, glyceryl monocaprylate: 0.99, IPBC:1.61, ethanol: 0.79, IPA:0.79, neo-chiozol:0.76, IPM:0.86, hexyl laurate: 0.86.
Tests for evaluating the adhesion to the ceiling and wall surfaces and the uniformity of diffusion of specific pest control ingredients were conducted in examples 1 to 16 and comparative examples 1 to 3 (1). The test results are shown in Table 2.
(1) Ceiling/wall adhesion and diffusion uniformity of specific pest control ingredient
Glass plates of 20cm×20cm were placed on the floor 6, ceiling 2 and wall 4 of a closed small room (width 1.8m, depth 1.3m and height 1.8 m) having a volume of 4.2m 3. Standing at one of the 4 corners of the cubicle, the aerosol product to be tested was sprayed 2 times in a slightly obliquely upward direction from a height of 1m from the floor toward the center of the space. After 20 minutes from the spraying, the glass plate provided on the floor, the glass plate provided on the ceiling, and the glass plate provided on the wall were taken out, and the specific harmful substance-removing component attached thereto was washed out with acetone, and analyzed by gas chromatography. Based on the analysis values obtained, the proportion of the amount of the control component adhering to the ceiling and the wall surface relative to the amount of the control component adhering to the floor surface was determined from the spray treatment for 20 minutes, and the ceiling/wall surface adhesion was evaluated. The evaluation results were shown in the order of A, B, C stages from the ceiling and wall adhesion to the good. The diffusion uniformity was evaluated based on the amounts of the control components attached to the ceiling and the wall, respectively. For the evaluation results, the 3-stage representation of A, B, C was performed in order from the one with good diffusion uniformity.
TABLE 2
As a result of the test, the ceiling and wall adhesion of the specific pest control ingredient was good, as compared with the quantitative injection aerosol products for pest control of examples 1 to 16. Among them, examples 1,3 to 10 and 12 to 15 having a specific gravity of 0.76 to 0.88 at 20℃are excellent in that not only the ceiling/wall adhesion of the specific pest control ingredient is good, but also the diffusion uniformity is good. From these results, it was found that the quantitative injection aerosol product for controlling specific pests according to the present invention has a confirmed effect of controlling specific pests including harmful microorganisms and/or harmful fine substances in a space.
In contrast, the pump-type spray product of comparative example 1 and the quantitative spray aerosol product of comparative example 3 in which the specific gravity of the aerosol stock solution exceeds 0.95 at 20 ℃ had low ceiling/wall adhesion as the control component. This is considered as follows: the pump-type spray product of comparative example 1 and the quantitative spray aerosol product of comparative example 3 were insufficient in the effect of controlling specific harmful substances including harmful microorganisms and/or harmful fine substances in the space.
The quantitative injection aerosol product of comparative example 2 having an internal pressure exceeding 0.60MPa at 25 ℃ is insufficient in terms of uniformity of diffusion to the ceiling and wall surfaces.
