Abstract
Description
Technical Field
[0001] The present invention relates to a metered spray aerosol composition for controlling harmful substances and a metered spray aerosol product.
Background Art
[0002] It is difficult to spray a chlorine-based mold remover or the like on high places such as ceilings and walls from the viewpoint of safety, and once mold occurs, it is a place that is difficult to deal with. A method for easily removing mold in every corner of a room, including such places, and keeping the interior clean is desired. In recent years, as a method of spraying a chemical agent in a bathroom or the whole room, a method using a fumigation-type mold control agent (Patent Document 1 etc.) or a full-amount spray aerosol-type mold control agent (Patent Document 2 etc.) has been proposed.
[0003] However, since a fumigation-type mold control agent generates smoke, there are also consumers who do not prefer this method. In addition, since a full-amount spray aerosol-type mold control agent is used up, when it is desired to treat a plurality of rooms, it is necessary to purchase as many as the number of rooms, and it is hardly economically preferable. On the other hand, a metered spray aerosol agent does not generate smoke, can be easily chemically treated by one operation, and is also excellent economically, so it is expected as a mold control agent to replace a fumigant or a full-amount spray aerosol agent.

Summary of the Invention
Problems to be Solved by the Invention
[0005] So far, metered-dose aerosol agents have been put into practical use and marketed in the fields of insecticides, deodorants, etc. However, in the field of fungicides, the metered-dose aerosol type has not yet been put into practical use. Fungi have strong vitality among microorganisms and are characterized by spreading due to air currents, so long-term control effect sustainability is required. Therefore, the technologies in the fields of insecticides, deodorants, etc. cannot necessarily be directly applied.
[0006] Also, when a metered-dose aerosol composition in which a fixed amount is sprayed in one operation is sprayed onto a hard surface such as a ceiling or a wall surface, there may be a case where the metered-dose aerosol composition bounces back, and it is not sufficiently adsorbed onto the hard surface such as a ceiling or a wall surface, resulting in a decrease in the adhesion of the fungicide component to the ceiling or wall surface.
[0007] In view of the above problems, an object of the present invention is to provide a metered-dose aerosol composition and a metered-dose aerosol product that are excellent in the adhesion of a fungicide component to high places such as ceilings and wall surfaces and excellent in fungicidal effects in a metered-dose aerosol type fungicide.

[0008] In order to achieve the above object, the present inventors conducted intensive studies to enhance the adhesion of the fungicide component to the ceiling and wall surfaces.

[0010] According to the present invention, there can be provided a metered - dose aerosol composition and a metered - dose aerosol product which are excellent in the adhesiveness of the mold - controlling component to hard surfaces such as ceilings and wall surfaces and have an excellent mold - controlling effect. [Embodiments for Carrying Out the Invention]
[0011] Hereinafter, the metered - dose aerosol composition and the metered - dose aerosol product of the present invention will be described. However, the present invention is not intended to be limited to the configurations described in the embodiments below. When there is a notation "~" indicating a range in this specification, it includes the upper and lower limits. When it is denoted as an SP value in this specification, it means the SP value at 25°C by Fedors' method [(cal / cm 3 ) 1 / 2 .
[0012] [Metered - dose aerosol composition] The metered - dose aerosol composition which is one embodiment of the present invention contains (A) a mold - controlling component and (B) one or more organic solvents having an SP value [(cal / cm 3 ) 1 / 2 of 7.2 to 13.0 at 25°C by Fedors' method, and a propellant (G). Hereinafter, each will be described.
[0013] [Aerosol stock solution (L)] The aerosol stock solution (L) contains (A) a mold control component and (B) one or more organic solvents having an SP value [(cal / cm 3 ) 1 / 2 of 7.2 to 13.0 at 25°C by the Fedors method.
[0014] The SP value is a measure of the solubility of a binary solution defined by the regular solution theory. Specifically, it is empirically known that the smaller the difference in the SP values of the two components, the greater the solubility. In its original definition, the SP value is a measure of the solubility of a liquid, but there is an idea that it can also be applied to polymers and the like so as not to conflict with the solubility of a polymer in a solvent with a known SP value.
[0015] By the way, when attaching the mold control component to high places such as the ceiling and wall surface (especially the upper part of the wall surface), gravity acts on the particles of the aerosol composition containing the mold control component in a direction different from the attachment direction (downward). As a result, the adhesive force is likely to decrease compared to the case of attaching the aerosol composition to the floor surface. Also, a metered spray aerosol composition containing an aerosol stock solution containing an insecticidal component and a propellant is known, but in order to suppress the generation of mold over a long period of time, it is necessary to keep the aerosol composition containing the mold control component adhered to the treatment surface for a longer time than the aerosol composition containing the insecticidal component.
[0016] Therefore, in order to enhance the adhesiveness of the mold control component to high places such as the ceiling and wall surface, it is important to improve the adsorptivity of the aerosol composition to the hard surface when the metered spray aerosol composition comes into contact with the hard surface such as the ceiling and wall surface.
[0017] Therefore, as materials for hard surfaces such as the ceiling and wall surface, vinyl chloride resin (SP value of 11.0 [(cal / cm 3 ) 1 / 2 ) or polyethylene terephthalate resin (SP value of 12.4 [(cal / cm 3 ) 1 / 2By making the SP value of []) close to the SP value of the aerosol stock solution (L), the adsorptivity of the aerosol composition to hard surfaces such as ceilings and wall surfaces can be enhanced, resulting in an aerosol composition having excellent adhesion of the mold control component to the ceiling and wall surfaces.

[0020] Among the above-mentioned mold control components, it is preferable to contain one or more selected from the group consisting of isopropylmethylphenol, thymol, 3-iodo-2-propynyl butylcarbamate, benzalkonium chloride, tebuconazole, monocaprin, monocaprylin, 1,4-bis[3,3´-(1-decylpyridinium)methyloxy]butane dibromide, silver, silver ions, and silver zeolite. When optical isomers based on asymmetric carbon atoms or geometric isomers based on double bonds exist for each component, each of them or any mixture thereof may be used.
[0021] The content of the mold control component (A) in the aerosol stock solution (L) is preferably 0.01 to 70 [w / v%], more preferably 0.05 to 50 [w / v%], and even more preferably 0.1 to 40 [w / v%]. If the content of the mold control component (A) in the aerosol stock solution (L) is within the above range, the mold control effect will be more excellent.
[0022] ((B) organic solvent) (B) The organic solvent is one or more kinds with an SP value [(cal / cm 3 ) 1 / 2 at 25 °C by the Fedors method of 7.2 to 13.0, preferably one or more kinds with an SP value [(cal / cm 3 ) 1 / 2 at 25 °C by the Fedors method of 8.2 to 13.0. (B) The organic solvent is stably dissolved in the aforementioned mold control component (A) and the liquefied petroleum gas and / or hydrofluoroolefin which are (G) propellants, and is formulated as a solvent for forming a uniform aerosol composition. Further, (B) the organic solvent is formulated to enhance the adsorptivity of the aerosol composition to hard surfaces such as ceilings and walls, and to improve the adhesiveness of the mold control component to high places such as ceilings and walls.
[0023] (B) By using one or more kinds with an SP value [(cal / cm 3 ) 1 / 2 at 25 °C by the Fedors method of 7.2 to 13.0, preferably one or more kinds with an SP value [(cal / cm 3 ) 1 / 2 at 25 °C by the Fedors method of 8.2 to 13.0, the adhesiveness of the mold control component (A) to high places such as ceilings and walls is excellent, and the mold control effect is more excellent. In the present invention, when containing two or more kinds of solvents, it is sufficient that the SP value of any one organic solvent alone satisfies the above range, rather than the SP value of the mixture.
[0024] Here, the SP value [(cal / cm 3 ) 1 / 2is obtained by Fedors' method. The definition and calculation of Fedors' method are described in "R.F. fedors: Polym. Eng. Sci. 14〔2〕, 147―154 (1974)". According to Fedors' method, the SP value [(cal / cm 3 ) 1 / 2 of each substance at 25 °C can be obtained by the following calculation formula. σ = [ΣE COH / ΣV] 1 / 2 In the formula, σ: solubility parameter, E COH : cohesive energy [cal / mol], V: molar molecular volume [cm 3 / mol].
[0025] (B) The organic solvent has an SP value [(cal / cm 3 ) 1 / 2If it is 7.2 to 13.0, there is no particular limitation.

In addition to the organic solvent, the SP value [(cal / cm 3 ) 1 / 2may contain an organic solvent that is not 7.2 to 13.0 [for example, 2,2,4-trimethylpentane (SP value: 7.0), propylene glycol (SP value: 13.5), ethylene glycol (SP value: 14.2), etc.]. (B) The content of the organic solvent having an SP value at 25 °C [(cal / cm 3 ) 1 / 2 of 7.2 to 13.0 is not particularly limited, but from the viewpoint of enhancing the adsorption of the aerosol composition to a hard surface such as a ceiling or a wall surface and improving the adhesion of the mold control component to a high place such as a ceiling or a wall surface, it is preferably 50% by volume or more, and more preferably 70% by volume or more.
[0027] Among the organic solvents having an SP value at 25 °C [(cal / cm 3 ) 1 / 2 of 7.2 to 13.0, (A) From the viewpoints of solubility in the mold control component and usability as a quantitative spray aerosol composition, ethanol, isopropanol, isopropyl myristate, octyl palmitate, isopropyl palmitate, isobutyl oleate, butyl stearate, n-dodecane, n-tetradecane, isodecane, and isododecane It is preferably contained one or more selected from the group consisting of, and more preferably contained one or more selected from the group consisting of ethanol, isopropanol, and isopropyl myristate.

In particular, 0.1 to 2.0 mL is preferable, 0.2 to 1.0 mL is more preferable, and 0.4 to 0.9 mL is even more preferable.
[0038] The volume of the aerosol container is not particularly limited, but is preferably 20 to 500 mL, more preferably 20 to 250 mL. By setting the volume of the aerosol container within the above range, it is easy to hold by hand and the spraying operation is easy even when treating high places such as the ceiling and wall surface.
[0039] (Spraying member) The metered spray aerosol product has a spraying member attached to the metered spray valve. The spraying orifice of such a spraying member preferably has a spraying orifice diameter of 0.2 to 3.0 mm, more preferably 0.2 to 2.0 mm, and even more preferably 0.2 to 1.2 mm. If the spraying orifice diameter is within the above range, the spraying force can be appropriately adjusted within a range. The shape (cross-sectional shape) of the spraying orifice is not particularly limited, and examples include a circle, a polygon such as a square, an ellipse, etc., and a circle is preferred. Here, the spraying orifice diameter means the major axis of the ellipse when the shape of the spraying orifice is an ellipse, and means the diameter of the circumscribed circle of the polygon when the shape of the spraying orifice is a polygon. Also, there may be one spraying orifice, or two or more spraying orifices.
[0040] The spraying orifice of the metered spray aerosol product of the present invention preferably has an elevation angle of the spraying orifice with respect to the horizontal plane set at 0 to 60°. If the elevation angle of the spraying orifice with respect to the horizontal plane is within the above range, spraying failure is less likely to occur and the aerosol composition can be stably sprayed. For the elevation angle of the spraying orifice of the nozzle or actuator having two spraying orifices with respect to the horizontal plane, it is the elevation angle of the perpendicular bisector of the line segment connecting the centers of each spraying orifice with respect to the horizontal plane. For a nozzle or actuator having three or more spraying orifices, the elevation angle of the spraying orifice with respect to the horizontal plane is determined as follows. For those in which the spraying orifice exists at the center of the spraying portion of the nozzle or actuator, it is the elevation angle of the orthogonal line passing through the center of the central spraying orifice with respect to the horizontal plane. For those in which the spraying orifice does not exist at the center of the spraying portion of the nozzle or actuator, it is the elevation angle of the orthogonal line passing through the center of the circumscribed circle of the polygon connecting the centers of each spraying orifice with respect to the horizontal plane.
[0041] In the case of a metered-dose aerosol product, the internal pressure of the aerosol container is set to 0.60 MPa or less at 25°C. In particular, 0.10 to 0.60 MPa is preferable, 0.13 to 0.60 MPa is more preferable, and 0.15 to 0.50 MPa is even more preferable. By setting the internal pressure of the aerosol container at 25°C within the above range, the adhesion of the (A) mold control component to high places such as ceilings and wall surfaces is excellent, and the mold control effect is excellent.
[0042] In the case of a metered-dose aerosol product, at a position 15 cm away from the spray port at 25°C, the spraying force is preferably 2.0 to 40.0 gf, more preferably 2.0 to 35.0 gf, and even more preferably 3.0 to 30.0 gf. If the spraying force is within the above range, the adhesion of the (A) mold control component to high places such as ceilings and wall surfaces is excellent, and the mold control effect is excellent. Such a spraying force can be appropriately adjusted according to the composition of the aerosol stock solution (L), the type of the propellant (G), the internal pressure of the aerosol product, and the dimensions and shape of the spray port. In this embodiment, the spraying force of the metered-dose aerosol product was measured with a digital force gauge (FGC-0.5, manufactured by Nidec-Shimpo Corporation).
[0043] In the metered-dose aerosol product for controlling harmful microorganisms of the present invention, when the spraying member is operated to spray the aerosol stock solution in the aerosol container, the spray particles formed preferably have a 50% particle diameter in the volume integral distribution at a distance of 30 cm from the spray port at 25°C adjusted to 17 to 120 μm, more preferably adjusted to 19 to 115 μm, and even more preferably adjusted to 23 to 95 μm.
[0044] If the 50% particle size in the volume integral distribution at a distance of 30 cm from the injection port at 25°C is within the above range, when the aerosol is injected in an indoor space, a sufficient amount of the (A) mold control component (harmful microorganism control component) will uniformly adhere to high places such as the ceiling and walls, and a practically sufficient control effect against harmful microorganisms can be obtained. The 50% particle size in the volume integral distribution of the injected particles can be appropriately adjusted according to the composition of the aerosol stock solution (L), the components of the propellant (G), the ratio of the propellant (G), the internal pressure of the aerosol container, the shape of the injection port, the nozzle length, etc.
[0045] In the present invention, the 50% particle size in the volume integral distribution of the injected particles means the volume average particle size (Dv50) measured by a particle size distribution measuring device and analyzed by an automatic calculation processing device. Specifically, the 50% particle size in the volume integral distribution of the injected particles is measured at 25°C using a laser particle size distribution measuring device (SPRAYTEC model STP5321, manufactured by Malvern), and the position of the aerosol is adjusted so that the distance between the laser beam irradiated from the laser light emitting part to the light receiving part and the injection port of the quantitative injection aerosol for harmful microorganism control is 30 cm, and the injected particles pass perpendicularly through the laser beam. Then, the measurement is performed during the injection of the aerosol, the particle size distribution of the injected particles is analyzed by an automatic calculation processing device, and the 50% particle size in the volume integral distribution of the spray particles can be obtained.
[0046] The quantitative injection aerosol product is for gaps less than 2.0 m 3 narrow spaces of about 2.0 to 18.8 m 3 a volume corresponding to a room of about 4.5 to 8 tatami mats, which is about 18.8 to 33.3 m 3 (area 7.5 to 13.3 m 2 height 2.2 to 3.0 m) indoor space, a volume corresponding to a room of 8 to 16 tatami mats, which is about 33.3 to 66.6 m 3 (area 13.3 to 26.6 m 2 height 2.2 to 3.0 m) in a relatively large indoor space such as indoors and outdoors, and is not particularly limited. The quantitative injection aerosol product exhibits particularly excellent effects in "narrow spaces", with a volume of 2.0 to 18.8 m 3A certain degree of space is assumed, for example, enclosed or semi-enclosed spaces such as bathrooms, dressing rooms, washrooms, toilets, closets, wardrobes, automobiles, tents, warehouses, storage rooms, garages, and entrances can be mentioned. More specifically, for example, as a narrow space with a volume of 2.0 to 3.0 m 3 For a narrow space with a volume of 3.0 to 18.8 m 3 For a narrow space with a volume of 3.0 to 18.8 m, bathrooms, dressing rooms, etc. are preferred.
[0047] In the case of a metered spray aerosol product, the release amount of the mold control component (A) into the air is preferably set to 0.01 to 250 mg / m 3 and more preferably set to 0.025 to 125 mg / m 3 If the release amount of the mold control component (A) into the air is within the above range, the adhesion of the mold control component (A) to high places such as the ceiling and wall surface is excellent, and the mold control effect is also more excellent.
[0048] In the case of a metered spray aerosol product, the injection amount of the mold control component (A) may be set so that the release amount of the mold control component (A) into the air is 0.01 to 250 mg / m 3 by one injection, or the injection amount of the mold control component per time may be set so that the release amount of the mold control component (A) into the air is 0.01 to 250 mg / m 3 by two or more injections. From the viewpoint of being able to adhere a sufficient amount of the mold control component (A) to high places such as the ceiling and wall surface and obtaining an excellent control effect against mold, it is preferably set so that the release amount of the mold control component (A) into the air is 0.01 to 250 mg / m 3 by two or more injections. Such a release amount of the mold control component (A) can be implemented by appropriately adjusting the composition of the aerosol stock solution (L), the volume ratio (L / G) of the aerosol stock solution (L) to the propellant (G), and the injection volume per time of the metered spray valve within the above ranges respectively.
[0049] In the case of a metered spray aerosol product, the ratio of the adhesion weight of the (A) mold control component to the treatment surface such as the ceiling or wall surface is preferably 5% or more, more preferably 10% or more, based on the total weight of the (A) mold control component sprayed theoretically.
[0050] A metered spray aerosol product can generally control molds on the ceiling and upper part of the wall for approximately one week to two months with a single application. By adjusting the composition of the aerosol stock solution (L), the type of the propellant (G), etc., it is possible to make the mold control period less than one week or more than two months.
[0051] <Mold> The molds to be controlled in the present invention include Aspergillus niger, Aspergillus versicolor, Penicillium sp., Monascus sp., Acremonium sp., Rhizopus sp., Mucor sp., and Monascus ruber, etc. The sources of these molds include bathrooms, dressing rooms, toilets, air conditioners, ventilation fans, washing machines, closets, wardrobes, windows, outer walls, wallpapers, curtains, mattresses, etc.
[0052] <Mold control method> The mold control method is carried out by spraying the above-mentioned metered spray aerosol product toward high places such as the ceiling and wall surface in an indoor or outdoor space. When the mold control method of the present invention is implemented, the adhesion of the (A) mold control component to high places such as the ceiling and wall surface is excellent, and the mold control effect is excellent. Here, the spraying amount of the metered spray aerosol product is adjusted so that the release amount of the (A) mold control component into the air is 0.01 to 250 mg / m 3 and preferably adjusted so that it is 0.025 to 125 mg / m 3 and more preferably adjusted so that it is. If the release amount of the (A) mold control component is within the above range, a more excellent control effect against molds can be exhibited.
[0053] In the mold control method of the present invention, it is preferable to inject the metered injection aerosol product at an injection direction angle of 0 to 60° with respect to the horizontal plane, and more preferably at an injection direction angle of 30 to 60°. Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.

[0062] In Table 1 and Table 2 above, Compound A is 1,4-bis[3,3´-(1-decylpyridinium)methyloxy]butane dibromide, IPMP is isopropylmethylphenol, IPA is isopropanol, IPM is isopropyl myristate, PG is propylene glycol, PGMPG is propylene glycol methyl-n-propyl ether, LPG is liquefied petroleum gas, HFO1234ze is trans-1,3,3,3-tetrafluoropropene, and DME is dimethyl ether, respectively.
[0063] [Production Example 5] (A) 1,4-bis[3,3´-(1-decylpyridinium)methyloxy]butane dibromide (hereinafter also referred to as Compound A, 0.5 w / v%) was dissolved in (B) ethanol (SP value: 12.6 [(cal / cm 3 ) 1 / 2 ) to prepare an aerosol stock solution (L). 50 mL of the aerosol stock solution (L) and 50 mL of liquefied petroleum gas (G) as a propellant were pressure-filled into an aerosol container with a metering valve (pressure-resistant container, volume 200 mL) having a spray volume of 0.8 mL so that the volume ratio (L / G) was 50 / 50 to obtain the metered-dose aerosol composition and the metered-dose aerosol product of Invention 27.

The internal pressure of this metered - dose aerosol product at 25°C was 0.45 MPa.
Example
[0065] Using the metered - dose aerosol composition and the metered - dose aerosol product produced in Example 1, the following tests were carried out on (A) the adhesiveness of the mold - control component and the mold - control effect.
[0066] (1) Confirmation test of the ceiling adhesiveness of the mold - control component In a closed small room with a volume of 3.6 m 3 (width 1.2 m, depth 1.6 m, height 1.9 m), vinyl chloride plates of 20 cm × 20 cm were installed at a total of 5 locations, namely the center and the four corners of the ceiling (ceiling surface material: vinyl chloride resin, SP value [(cal / cm 3 ) 1 / 2 ) at 25°C by the Fedors method being 11.0). Standing near the center of the room, the test aerosol product of the first invention was sprayed 4 times from a height of 1.5 m from the floor towards the four corners of the ceiling in a slightly obliquely upward direction. 20 minutes after spraying, the vinyl chloride plates installed on the ceiling were taken out respectively, and the adhered (A) mold - control component was washed out with ethanol, and the absorbance at a wavelength of 264 nm was measured using a spectrophotometer (UV - 1800, manufactured by Shimadzu Corporation) to analyze the adhered weight of the (A) mold - control component. The analysis value of the adhered weight of the obtained (A) mold - control component was multiplied by (120×160) / (20×20×5)=9.6 to calculate the adhered weight of the (A) mold - control component on the entire ceiling.
[0067] The ratio of the weight of the (A) mold control component adhering to the entire ceiling to the total weight of the theoretically sprayed (A) mold control component was determined, and the ceiling adhesion of the (A) mold control component was evaluated in three grades of A, B, and C in descending order according to the following evaluation criteria. The same tests were also carried out for Inventions 2 to 9 and Comparative Example 1. The test results are shown in Table 3. A; The mold control component adhering to the ceiling is 10% or more B; The mold control component adhering to the ceiling is 5% or more C; The mold control component adhering to the ceiling is less than 5%
[0068] (2) Confirmation test of mold control effect In a closed volume of 3.6 m 3 (width 1.2 m, depth 1.6 m, height 1.9 m), four plastic petri dishes with a diameter of 6 cm and the lids removed were installed at the four corners of the ceiling (the material of the ceiling surface: vinyl chloride resin, SP value [(cal / cm 3 ) 1 / 2 at 25 °C by the Fedors method was 11.0). Standing near the center of the unit bath, the test aerosol product of Invention 1 was sprayed 2 times (8 times in total) from a height of 1.5 m from the floor towards the four corners of the ceiling. After leaving it for 15 minutes, ventilation was carried out and the petri dishes were collected. To this petri dish, 100 μL of a mixture of a Cladosporium cladosporioides (a kind of black mold) spore dispersion liquid and a GP medium diluted 2-fold with sterilized water in a ratio of 1:1 was added, and it was cultured for 1 week under humid conditions at 25 °C. Also, as a control example, one without dropping the test solution was prepared in the same way. The same tests were also carried out for Inventions 2 to 11 and Comparative Example 1.
[0069] One week later, the growth status of the mold treated with the test aerosol products of Inventions 1 to 11 and Comparative Example 1 was visually observed, and the mold control effect was evaluated according to the following evaluation criteria. The test results are shown in Table 3. (Evaluation criteria) A; The occurrence of mold can hardly be confirmed visually. B; The amount of mold growth is less than that of the control example. C; The amount of mold growth is the same as that of the control example.
[0070]
Table 3
[0071] As a result of the tests, in Inventions 1 to 11 of the present invention containing ethanol, isopropanol, isopropyl myristate, n-dodecane, and isododecane with an SP value of 7.2 to 13.0 as the (B) organic solvent, the ceiling adhesion and mold control effect were excellent. This is presumably because the value of the SP value of the vinyl chloride resin, which is the material of the ceiling surface, is 11.0, and the SP value of the (B) organic solvent is close at 7.2 to 13.0, and the high affinity also contributed to the improvement of the ceiling adhesion and mold control effect. Among them, in Inventions 1 to 6, Invention 8, and Invention 11 of the present invention containing only ethanol, isopropanol, and isopropyl myristate with an SP value of 8.2 to 13.0, which is closer to the SP value of the ceiling resin, or two or more selected from the group consisting of ethanol, isopropanol, and isopropyl myristate, the ceiling adhesion and mold control effect were more excellent. Further, Invention 9 in which the organic solvent having an SP value of 7.2 to 13.0 is 70% by volume with respect to the total amount of the (B) organic solvent was found to be more excellent in ceiling adhesion and mold control effect compared to Invention 10 in which the organic solvent having an SP value of 7.2 to 13.0 is 50% by volume with respect to the total amount of the (B) organic solvent.
[0072] On the other hand, in Comparative Example 1 containing propylene glycol with an SP value [(cal / cm 3 ) 1 / 2 exceeding 13.0 at 25°C by the Fedors method as the (B) organic solvent, both the ceiling adhesion and mold control effect were insufficient.
[0073] (3) Confirmation test of the ceiling and wall adhesion of the mold control component when the injection force is changed Enclosed volume of 4.2 m 3In a small room (width 1.8 m, depth 1.3 m, height 1.8 m), 20 cm × 20 cm vinyl chloride plates were installed at 6 locations on the floor, 2 locations on the ceiling, and 4 locations on the wall. Standing at one of the four corners of the small room, the test aerosol product of the present invention 12 was sprayed twice obliquely upward slightly towards the center of the space from a height of 1 m above the floor. 20 minutes after the spraying, the vinyl chloride plates installed on the floor, the vinyl chloride plates installed on the ceiling, and the vinyl chloride plates installed on the wall were taken out respectively, and the mold control component adhering thereto was washed out with ethanol, and the absorbance at a wavelength of 264 nm was measured using a spectrophotometer (manufactured by Shimadzu Corporation, UV-1800) to analyze (A) the adhering weight of the mold control component. Based on the obtained analysis values, the ratio of the adhering weight of the mold control component (A) adhering to the ceiling and the wall to the adhering weight of the mold control component (A) adhering to the floor by 20 minutes after the spraying treatment was determined, and the ceiling / wall adhesiveness was evaluated. The same tests were also carried out for the present inventions 13 to 26 and Comparative Example 2. Regarding the evaluation results, they were shown in three levels of A, B, and C in order from those with good ceiling / wall adhesiveness according to the same evaluation criteria as in Table 3. The test results are shown in Table 4.
[0074]
Table 4
[0075] As a result of the test, in the present inventions 12 to 26 which are quantitative spray aerosol compositions and quantitative spray aerosol products containing ethanol, isopropyl alcohol, and isopropyl myristate with an SP value of 7.2 to 13.0 as the (B) organic solvent, the ceiling / wall adhesiveness was excellent. Among them, the present inventions 12 to 25 which are quantitative spray aerosol products with an injection force of 2.0 to 40.0 gf at a position 15 cm from the injection port at 25°C were particularly excellent in terms of ceiling / wall adhesiveness. On the other hand, Comparative Example 2 which is a pump spray product containing ethanol with an SP value of 12.6 as the (B) organic solvent and having an injection force of 2.0 gf resulted in insufficient ceiling / wall adhesiveness.
[0076] (4) Practical use test in the bathroom [Test Example 1] Volume 3.6 m 3 In a unit bath with dimensions (width 1.2 m, depth 1.6 m, height 1.9 m), stand near the center of the unit bath and spray the metered aerosol product of the second invention from a height of 1.5 m from the floor towards the four corners of the ceiling (ceiling surface material: vinyl chloride resin, SP value [(cal / cm 3 ) 1 / 2 at 25°C by the Fedors method is 11.0) twice each (for a total of 8 times).
