[Problems to be Solved by the Invention]

However, as in the method of Patent Document 1, the method of rapidly dispersing the pharmaceutical particles into the processing space, and then quickly dissipating the fragrance of the fragrance does not sufficiently provide a deodorizing effect to the continuously generated malodorous system. Will become incomplete. It is only said that the toilets in general houses are narrow spaces of about 2.5 to 3.5 m ^3. Therefore, the increase in the amount of pharmaceutical particles released into the processing space will make users in the processing space feel the pharmaceutical particles strongly. Fragrance, especially worrying about consumers who do not like strong fragrances.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an aerosol for deodorization, which can exhibit immediate and effective deodorizing effects in a treatment space such as a toilet. [Means to solve the problem]

A characteristic structure of the aerosol for deodorization of the present invention for solving the above-mentioned problems is an aerosol for deodorization, which is provided with an aerosol dope and a propellant containing a deodorant component and an organic solvent enclosed therein. The pressure-resistant container of the quantitative injection valve is connected to the injection button of the quantitative injection valve provided with an injection port. When the injection button is pressed once, the injection volume becomes 0.1 to 0.4 mL, and the injection force at an injection distance of 20 cm is Adjust at 25 ° C to 0.3 ~ 10.0g‧f. When the spray button is pressed once to spray the aerosol raw liquid in the pressure-resistant container to a processing space of 2.5 ~ 3.5m ³ , the sprayed gas 50% by volume or more of the sol stock solution is configured such that adhesive particles adhered to the exposed portion in the processing space are formed within 60 minutes.

The foul odor in the toilet is not only trapped in the air of the processing space, but also continuously generated from the foul odor sources such as urine adhering to the wall, the floor, and the like. The present inventors have considered that improving the deodorizing effect on malodor generated from a malodor source attached to a wall surface or the like is related to the improvement of the deodorizing effect on the malodor in the toilet. Therefore, 50% by volume or more of the aerosol dope which has been sprayed into the processing space in the aerosol system for deodorization according to the present invention is defined as one that forms adherent particles. Adhesive particles are aerosols for deodorization. Among the spray particles formed when the aerosol raw solution is sprayed into a processing space of 2.5 to 3.5 m ³ , they adhere to the exposed part of the processing space within 60 minutes after spraying. (For example, particles that are present on the floor or wall surface of a toilet space, the surface of a structure such as a toilet, etc.). Therefore, it is possible to effectively deodorize both the malodor generated from the malodor source attached to the exposed portion and the malodor remaining in the gas of the processing space, and the deodorizing effect of the entire processing space can be improved. In addition, even if ejection particles (referred to as "floating particles") other than the adhesive particles are diffused throughout the entire processing space, the concentration of the aerosol dope in the processing space is reduced only by the amount of the adhesive particles. Therefore, the amount of particles of the aerosol dope inhaled by the user in the processing space becomes extremely small, and excessive aroma that is felt by the aerosol dope itself can be suppressed. The aerosol for deodorization of the present invention has a spray volume of 0.1 to 0.4 mL when the spray button is pressed once, and a spray force of 20 cm at a spray distance of 0.3 to 10.0 g · f at 25 ° C.

A 90% particle size is preferably 40 to 60 μm.

By adjusting the particle diameter of the spray particles to the above-mentioned optimal range, a part of the spray particles becomes adherent particles, and the remainder becomes floating particles. Therefore, according to the deodorizing aerosol of this structure, both the foul odor floating in the air of the processing space and the foul odor generated from the foul odor source attached to the exposed portion can be deodorized.

According to the deodorizing aerosol of the present configuration, when the volume ratio (a / b) of the aerosol dope (a) and the propellant (b) is within the above-mentioned range, the aerosol is formed by the sprayed aerosol dope. The balance between the adhering particles and the floating particles becomes the best. Thereby, the adhering particle system can reliably reach the exposed portion in the processing space, and the floating particle system can float in the processing space without giving an unpleasant amount due to excessive aroma. In this way, the adhering particles and the planktonic particles each exist in an optimal state, and they can share their respective roles to maximize the effect of the deodorizing component.

In addition, when the aerosol dope is sprayed, the adherent particles and the planktonic particles can be formed in a well-balanced manner, and the deodorizing effect can be stabilized.

In the aerosol for deodorization concerning this invention, it is desirable that the said deodorant component system contains a plant extract and a harmonized fragrance.

According to the aerosol for deodorization of this structure, the odor of feces, urine, and the like in a toilet is harmonized with a fragrance, and the deodorizing effect which recognizes a bad odor as a good fragrance can be obtained.

In the aerosol for deodorization of the present invention, it is desirable that the aforementioned spray port has a spray diameter of 0.2 to 1.0 mm.

According to the deodorizing aerosol of this configuration, when the nozzle diameter is in the above-mentioned range, the balance between the adherent particles and the floating particles formed by the sprayed aerosol dope is optimal.

In the aerosol for deodorization concerning this invention, it is preferable that the said aerosol stock solution system further contains folate and / or folate.

According to the aerosol for deodorization of the present constitution, a treatment space for spraying the aerosol dope from the aerosol for deodorization can be provided so that the leaf alcohol or folic aldehyde, which is expected to have a relaxing effect of reducing fatigue and pressure, is contained in the aerosol dope For a more enjoyable space.

In the aerosol for deodorization according to the present invention, it is preferable that the sprayed aerosol raw liquid is spread to the entire processing space in 120 seconds.

According to the deodorizing aerosol of this structure, the sprayed aerosol raw liquid spreads throughout the entire processing space within 120 seconds. Therefore, even for ordinary people, the odor staying near the ceiling within the toilet time and staying in the The bad odor near the ground can exhibit a deodorizing effect with excellent immediate effect.

In the aerosol for deodorization of the present invention, it is desirable that the concentration of the aerosol dope in the air from the start of spraying to 120 seconds is at least 0.0007 ppm in 95% or more of the processing space.

Button; When pressing the spray button to spray the aerosol dope in the pressure-resistant container, more than 50% by volume of the sprayed aerosol dope can be formed as adherent particles. Adhesive particles are aerosols for deodorization. Among the spray particles formed when the aerosol raw solution is sprayed into a processing space of 2.5 to 3.5 m ³ , they adhere to the exposed part of the processing space within 60 minutes after spraying. Spray particles. Hereinafter, the aerosol for deodorization of this invention is demonstrated. However, the present invention is not intended to be limited to the embodiments described below or the structures described in the drawings.

<Aerosol dope> [Deodorant component] The deodorant component of the main component of the aerosol dope is preferably a plant-based deodorant component and a harmonized fragrance. The plant-based deodorizing component reacts with an offensive odorous substance to deodorize the malodor, so-called chemical deodorizing effect. As such a plant-based deodorizing component, an extract of a bell flower, a ginkgo, a fig, or the like can be appropriately selected. Any of these plant-based deodorizing components can be used alone or in a mixed state. In particular, it is desirable to use a plant-based deodorizing component that neutralizes by reacting with either an acidic gas or an alkaline gas. Alternatively, a plant-based deodorizing component that neutralizes an acid gas and a plant-based deodorizing component that neutralizes an alkaline gas may be used in combination.

A harmonized fragrance is a fragrance which intends to absorb bad odors, such as feces and urine odor, as one of the components of the fragrance, and converts them into a good fragrance (aroma). Therefore, a harmonized fragrance system has a deodorizing effect on the sense of smell which is recognized as a good fragrance in the environment where the malodor exists as one of the components of the fragrance. In the following, the unpleasant odor caused by malodor will be reduced by the sensory deodorizing effect, and the malodor will be moderated.

[Organic solvents] The organic solvent of the other main component of the aerosol dope is an aerosol dope prepared by dissolving the above-mentioned deodorant components. When the prepared aerosol dope is sprayed into the processing space, the most suitable one is formed. Particles. It is ideal as an organic solvent-based higher fatty acid ester and alcohol. The total number of higher fatty acid ester-based carbon numbers is preferably 16 to 20, and examples thereof include isopropyl myristate, butyl myristate, hexyl laurate, and isopropyl palmitate. Among these, isopropyl myristate is particularly suitable. The alcohol-based lower alcohol having 2 to 3 carbon atoms is preferred, and examples thereof include ethanol, isopropanol, and propanol. Among these, ethanol is particularly suitable. In the organic solvent system, for example, a hydrocarbon solvent such as n-alkane and isoalkane, or a glycol ether having 3 to 6 carbons, and a ketone solvent may be mixed.

[Other components] 除了 In addition to the above components, the aerosol for deodorant of the present invention can also be used as a fragrance, antifungal agent, antibacterial agent, fungicide, stabilizer, antistatic agent, etc. Defoamers, excipients, etc. are suitably formulated in an aerosol stock solution. For example, the aerosol stock solution contains a fragrance, and the odor of the fragrance can be masked by the fragrance of the fragrance. Examples of the fragrance include orange oil, lemon oil, lavender oil, peppermint oil, eucalyptus oil, citronella oil, lime oil, yuzu oil, jasmine oil, emu oil, green tea essential oil, limonene, and α-pinene. , Fragrant alcohol, geraniol, phenethyl alcohol, pentyl cinnamaldehyde, cumyl benzaldehyde, benzyl acetate, etc., blending cis-3-hexenol called `` green fragrance '' ) Or the flavor component of folate. The aerosol stock solution is set to the fragrance of citrus, rose and lavender through the blending of fragrances, which can satisfy consumer preferences. In addition, by deploying foliol, which is expected to reduce fatigue, stress, and other relaxation effects, when spraying an aerosol for deodorization into a toilet, the toilet can be made a more pleasant space. Examples of antifungal agents, antibacterial agents, and fungicides include fluorenol, 2-mercaptobenzothiazole, 2- (4-thiazolyl) benzimidazole, and 5-chloro-2-methyl-4-isothiazoline 3-one, trifolin, 3-methyl-4-isopropylphenol, o-phenylphenol, and the like.

<Propellant> As the propellant used in the deodorant aerosol of the present invention, liquefied petroleum gas (LPG), dimethyl ether (DME), nitrogen gas, carbon dioxide gas, nitrous oxide, compression Air etc. The above-mentioned propellant can be used alone or in a mixed state, but it is easy to use LPG as a main component.

The volume ratio (a / b) of the aerosol-based aerosol dope (a) and the propellant (b) for deodorization of the present invention is adjusted so as to be 10/90 to 50/50. By adjusting to such a range, at least a part of the sprayed aerosol dope can be formed as adhesive particles. Thereby, the adhering particle system can reliably reach the exposed portion in the processing space, and the floating particle system can float in the processing space without giving an unpleasant amount due to excessive aroma. In addition, in a case where both the adherent particles and the floating particles are formed, the balance between the two is optimal. In this way, each of the adherent particles and the planktonic particles exists in an optimal state, and they can share their respective roles to maximize the deodorizing effect. If the capacity ratio (a / b) is less than 10/90, that is, if the proportion of the propellant (b) enclosed in the pressure-resistant container is increased, the sprayed aerosol raw liquid is finer than necessary. As a result, adhesive particles are reduced. As a result, the adherent particles attached to the exposed portion in the processing space are insufficient, so that the malodor that continues to be generated from the malodor source attached to the exposed portion cannot be sufficiently deodorized, and the deodorizing effect may not be persistent. . On the other hand, if the capacity ratio (a / b) is changed to more than 50/50, that is, if the ratio of the propellant (b) enclosed in the pressure-resistant container is made smaller, it is difficult to spray the aerosol to be sprayed. The dope forms adhering particles and planktonic particles having particle diameters in an optimal range, so that the aerosol dope immediately settles as soon as the aerosol dope is sprayed. Therefore, the number of planktonic particles floating in the processing space is insufficient, and it becomes difficult to quickly deodorize the malodor.

<Aerosol for deodorization> As described above, deodorizing components, organic solvents, propellants, and other components formulated as necessary are selected to seal these into pressure-resistant containers to complete aerosol products. This aerosol product is the aerosol for deodorization of the present invention, and the aerosol raw liquid is sprayed on the processing space. The aerosol dope system is mainly composed of deodorant components and organic solvents. Strictly speaking, it is different from the propellant. However, the aerosol dope system and the propellant are simultaneously released to the outside of the pressure-resistant container. The explanation is that the aerosol contents including the aerosol dope and the propellant are handled as the "aerosol dope".

Hereinafter, the injection valve provided in the aerosol for deodorization concerning this invention is demonstrated. The aerosol system for deodorization of the present invention is mainly composed of a pressure-resistant container (aerosol container), a quantitative injection valve, and an injection button. A spraying button is connected to the actuating part of the aerosol dope to the quantitative spraying valve, and a spraying port for spraying the aerosol container to the outside (processing space) is provided on the spraying button.

When the spray button of the aerosol for deodorization has been pressed once, the quantitative spray valve is actuated by the pressure of the spray agent, and the aerosol raw liquid in the pressure-resistant container rises to the spray port and is sprayed into the processing space. The spray volume of the aerosol dope at this time is adjusted to 0.1 to 0.4 mL, and more preferably 0.2 to 0.4 mL. Within this range, at least a part of the aerosol dope is formed as adhesive particles. In addition, in the case where both the adhering particles and the floating particles are formed, they are formed in a balanced manner in the processing space so as to exhibit the best deodorizing effect. If the spraying volume is less than 0.1 mL, the spraying volume is too small, so that the adherent particles cannot sufficiently adhere to the exposed portion in the processing space, and it becomes difficult to continuously carry out the malodor generated from the malodor source that is adhering to the exposed portion. Deodorant. In addition, since the number of planktonic particles is also reduced, the deodorization of malodors floating in the air in the processing space becomes insufficient. On the other hand, if the ejection volume exceeds 0.4 mL, because the aerosol dope is released more than necessary in the processing space, there is a doubt that it may cause unpleasantness to consumers who do not like strong aromas, and because of the use of the aerosol dope The amount has become too large, so it is also economically disadvantageous.

The aerosol for deodorization is adjusted so that the spraying force at a distance of 20 cm from the spraying port is 25 ° C and becomes 0.3 to 10.0 g · f. With such a range, the adhesive particles formed from the aerosol dope can smoothly reach the exposed portion in the processing space by one shot, and the effect of the deodorant component can be exhibited quickly. Furthermore, the nozzle diameter of the injection port is ideally set to 0.2 to 1.0 mm. Within this range, the above-mentioned particle size and spraying force can be appropriately adjusted, and at least a part of the aerosol dope sprayed into the processing space is optimally formed as adhesive particles, and the malodor that is adhering to the exposed portion can be formed The malodor generated by the source continues to deodorize.

The particle diameter of the spray particles sprayed from the aerosol for deodorization is preferably adjusted to 25-60 ° C, and the 90% of the cumulative volume distribution of the spray distance is 15 to 40 μm. If it is within such a range, when the aerosol dope is sprayed in a processing space of 2.5 to 3.5 m ³ , 50% by volume or more of the sprayed aerosol dope may be formed as adherent particles, and a sufficient amount of adherence The particles can move quickly and adhere to exposed portions in the processing space. Therefore, it is possible to deodorize the malodor that continues to be generated from the malodor source that is adhering to the exposed portion by the deodorizing component of the adhesive particles. If the particle size of the sprayed particles is 25% and the 90% of the cumulative volume distribution of the spray distance is 15cm is less than 40 μm, the particle size is too small, so that many particles become difficult to reach the exposed portion, and a sufficient amount of adherent particles are not formed. . As a result, it becomes difficult to continue to generate a bad odor from a bad odor source adhering to the exposed part, and it is effective to deodorize. On the other hand, when the particle diameter exceeds 60 μm, the particle diameter becomes too large, so that it becomes difficult to control the behavior of the adhesive particles, and it becomes difficult to properly adhere to the exposed portion.

Furthermore, it is desirable that the particle size of the spray particles is adjusted to 10% of the cumulative volume distribution at 25 ° C. and a spray distance of 15 cm to 5 μm or less, and 50% of the particle size is preferably adjusted to 20 to 40 μm. The particle diameter distribution width of the jet particle system having such a cumulative volume distribution is wide. As a result, from the aerosol for deodorization, when the aerosol raw liquid is sprayed once into the processing space, adherent particles having a larger particle diameter and floating particles having a smaller particle diameter are formed.

Since the floating particles are formed to have a particle size smaller than that of the adherent particles, when the aerosol dope is sprayed into the processing space, it can rapidly diffuse and float in the processing space. Therefore, it is possible to deodorize the malodor remaining in the gas in the processing space by the deodorizing component of the floating particles. In this way, by adjusting the particle size to the optimal range as described above, a part of the sprayed aerosol raw liquid forms planktonic particles, and the planktonic particles behave differently from the adherent particles. Together with adherent particles, it effectively deodorizes malodor.

<Diffusion simulation> Fig. 1 is an explanatory diagram of a diffusion simulation when the aerosol for deodorization of the present invention is sprayed into a processing space of 3 m ³ . The analysis method of the drug concentration using the diffusion simulation in FIG. 1 will be described below.

When the drug concentration is analyzed, the state where the drug (aerosol stock solution) diffuses over time is output as the analysis result. Initially, the analysis is performed by the airflow calculation method until the spatial distribution of wind speed and temperature becomes stable. Then, the aerosol product is used to generate the medicine, and the analyzed wind speed distribution is used to calculate the medicine by the concentration calculation method. The spatial distribution of the concentration is predicted by stable analysis. In addition, the time-dependent change in the concentration distribution is predicted by transient analysis.

The calculation method of airflow is in the simulation space. The 3-D advection-diffusion equation is discretized by the finite difference method and solved numerically. The velocity and direction of the airflow (wind speed, wind direction), and air temperature ( Hereafter, it is referred to as a "flow state". The airflow calculation method is based on the k-ε turbulence mode (from the transport equation of momentum) based on the Navier-Stokes equations that set the velocity and direction of the airflow and the motion elements of the pressure as variables. (1), turbulent energy transfer equation (2), and turbulent dissipation rate transfer equation (3)), heat transfer equation (4), and continuous equations) (5) ~ (8) The formed advection diffusion equation is repeatedly calculated using the numerical analysis obtained by the finite difference method at each minute time between adjacent grid points of each micro-divided region. The wind speed between the grid points, When the wind direction, air temperature, and wind pressure become a specific equilibrium state, the value can be used to determine the predicted wind speed data, predicted wind direction data, and predicted temperature data for each of the grid points.

[Number 5]

The concentration calculation means is a means for calculating a concentration distribution in a simulation space by discretizing a three-dimensional concentration diffusion branch formula by a finite difference method and calculating the concentration distribution. That is, the concentration calculation means refers to the airflow state (predicted wind speed data, predicted wind direction data, and predicted air temperature data) of each grid point in the calculated minute division area, and the generation amount of the diffusing substance is set to a predetermined time. The formula for the concentration diffusion branch consisting of the transport equation (9) of (diffusion material) is repeatedly calculated between the adjacent grid points of each micro-divided region using the numerical analysis obtained by the finite difference method at each micro-time. In the case where the drug concentration between the aforementioned lattice points is in an equilibrium state, the value is used to determine a steady state solution as the predicted drug concentration data of the aforementioned lattice points. Furthermore, in the process of repeating the calculation, the cumulative value of the minute time and the concentration of the drug in each micro-divided area at that time are recorded at each specific time determined in advance, and the predicted drug can also be determined Non-stationary solution of concentration data. In addition, by setting the generation amount of the diffusing substance to a dimensionless amount, the predicted drug concentration data can be predicted not as an absolute value but also as a relative value corresponding to the generation amount of the diffusing substance. [Formula of transport of diffusive matter]

[Number 6]

As shown in Fig. 1 (a), the analysis object is a deodorizing aerosol that is set in a processing space (78 cm wide x 169 cm wide x 230 cm high) of about 3 m ³ and the deodorizing aerosol with the spray port 1a facing obliquely upward. Analytical shape of 1. This analytical shape and processing space are divided into analytical lattices.

The analysis conditions were set to a wind speed of 0 m / s, and the effects of heat and temperature indoor and outdoor were ignored. With the spray port 1a of the aerosol 1 for deodorization, the spray volume per time was set to 0.2 mL, and the spray force at a distance from the spray port to 20 cm was set to 2.9 g‧f at 25 ° C to spray the aerosol. Stock solution, the analysis of the spatial distribution of the concentration of the diffused aerosol stock solution in the air.

Fig. 1 (b) shows the aerosol dope after spraying the aerosol dope once from the aerosol 1 for deodorization into the processing space, and showing the aerosol dope after 10 seconds, 30 seconds, 60 seconds, 120 seconds, and 170 seconds. Image of the diffusion simulation of air concentration (ppm). In Figure 1 (b), the symbol A is attached to a region where the concentration of each image in the aerosol dope air is 0.0007 ppm. Based on the above analysis, as shown in Figure 1 (b), after spraying, the aerosol stock solution diffuses rapidly, and after spraying 60 seconds, it reaches the floor from the ceiling of the processing space to the floor, After 120 seconds, the results were spread to the entire processing space. The "diffusion to the entire processing space" here refers to the method shown in the image after 120 seconds in Figure 1 (b). The concentration of the aerosol stock solution in the air in the volume of 95% or more of the processing space becomes 0.0007 ppm or more. status. Incidentally, since the normal use time of a toilet is about 5 to 15 minutes, if the diffusion time of the aerosol dope to the entire toilet space is 120 seconds, the deodorization can be sufficiently performed during the use time of the toilet. Furthermore, the concentration of the aerosol dope which has diffused to the entire processing space after being sprayed to 170 seconds becomes the same. Therefore, after sufficient time has elapsed after the spraying, the adhesion of the adherent particles to all surfaces of the wall surface, the floor surface, and the ceiling surface in the processing space is completed, and the adhered state is maintained. Then, as described above, the malodor that continues to be generated from the malodor source that is adhering to the exposed portion is deodorized by the deodorizing component.

On the other hand, the planktonic particle-based deodorizing component volatilizes slowly, and deodorizes the malodor remaining in the air in the processing space. Especially in the toilet, the bad odors include urine odor due to ammonia, and fecal odor due to hydrogen sulfide, methyl mercaptan, etc. The ammonia type is lighter than air and easily stays near the ceiling. Hydrogen sulfide and methyl Thiols are heavier than air and tend to stay near the ground. However, as shown in FIG. 1 (b), the sprayed aerosol dope from the aerosol 1 for deodorization spreads throughout the processing space after being sprayed for 120 seconds, so the foul odor staying near the ceiling, and The stench that stays near the ground can be deodorized by floating particles. However, ammonia is an alkaline gas, and hydrogen sulfide and methyl mercaptan are acidic gases. The aerosol dope contains deodorizing components that can react with and neutralize alkaline gas and acid gas. Any kind of odorous substance can be deodorized by chemical deodorization. As the above-mentioned deodorizing component, it is desirable to use a mixture of a plant-based deodorizing component that can be neutralized by reacting with an alkaline gas and a plant-based deodorizing component that can be neutralized by reacting with an acidic gas, or both. It is a plant-based deodorant that is neutralized by the reaction with acidic gases.

As described above, since the aerosol for deodorization of the present invention is composed of two types of particles having different behaviors from the sprayed aerosol dope, each particle exists in an optimal state and can share its role. And maximize the deodorizing effect. Therefore, with the adherent particles and the planktonic particles, both the foul odor remaining in the gas in the processing space and the foul odor generated by the foul odor source that is adhering to the exposed portion in the processing space can be excellent. Deodorant effect.

As an analysis condition, when the ejection capacity and the ejection force are set smaller than in the diffusion simulation shown in FIG. 1, for example, when the ejection capacity per injection is set to 0.1 mL, The mode of setting the spraying force of the mouth at a distance of 20 cm to 0.4 g · f at 25 ° C. is the same as the diffusion simulation shown in FIG. 1, and the diffusion simulation result of the aerosol stock solution rapidly spreading to the entire processing space can be obtained. When the ejection capacity and ejection force are set to be larger than the diffusion simulation shown in Fig. 1, for example, the ejection capacity per time is set to 0.4 mL, and the ejection capacity is set at a distance of 20 cm from the ejection port. The mode of setting the spraying force to 7.0 g · f at 25 ° C. is the same as the diffusion simulation shown in FIG. 1, and a diffusion simulation result of the aerosol dope quickly spreading to the entire processing space can be obtained.

As described above, the deodorizing aerosol of the present invention sprays the aerosol raw liquid once to a processing space of 2.5 to 3.5 m ^{3 to} obtain a deodorizing effect excellent in immediateness and durability. The space of 2.5 ~ 3.5m ³ is roughly equivalent to the toilet space (80-85cm in width × 140-180cm in depth × 230cm in height of the ceiling) in a common house. Therefore, according to the aerosol for deodorization of the present invention, it is possible to quickly deodorize malodors in toilets and the like of a general house, and the deodorizing effect can be sustained for a long time. In addition, a part of the particles formed by spraying the aerosol for deodorization of the present invention into the aerosol dope in the processing space is formed as floating particles. Therefore, the concentration of the aerosol dope (floating particles) that is diffusing into the processing space is lower than that of the adherent particles, and the concentration of the processing space is lower. Therefore, the aroma from the planktonic particles is reduced, and it is possible to suppress an unpleasant feeling to consumers who do not like strong aromas. [Example]

<Deodorizing efficacy test> In order to confirm the deodorizing effect of the deodorizing aerosol of the present invention, an aerosol for deodorizing (Examples 4 and 5) prepared in the same manner as in Example 1 was prepared and olfactory measurement was performed. Deodorant efficacy test by law. For comparison, an aerosol for deodorization (Comparative Example 1) different from the components of the present invention was prepared, and the same deodorizing effect test was performed.

An aerosol for deodorization was prepared using the same raw materials and production method as those of the aerosol for deodorization in Example 1, except that a small amount of citrus flavor was added to the aerosol stock solution as a fragrance, and this was taken as Example 4. An aerosol for deodorization was produced using the same raw materials and production method as those of the aerosol for deodorization in Example 1 except that a small amount of orange flavor was added to the aerosol stock solution as a fragrance, and this was taken as Example 5.

In Comparative Example 1, a previously commercially available aerosol for deodorization was prepared using a formulated fatty acid salt as a deodorizing component, a quaternary ammonium salt as a bactericidal component, and ethanol as an organic solvent.

In the deodorizing efficacy test, a specific amount of odorous substances exhibiting simulated odor of feces and urine was distributed in a treatment space of 3 m ³ . After that, the aerosol for deodorization was sprayed once in the processing space, and after spraying (after 0 minutes), 5 minutes, 10 minutes, 20 minutes, 30 minutes, and 60 minutes, the odor in the processing space was sprayed. The sensory tester evaluates with the 9th order of pleasure and unhappiness. However, since the aerosol for deodorization of Comparative Example 1 is an aerosol product without a fixed-quantity injection valve, instead of the implementation of a single fixed-rate injection, continuous injection for 1 second was performed in accordance with the usage of Comparative Example 1. The amount of spray is measured before and after spraying, and is calculated from the weight difference.

Level 9 Pleasure and Unpleasantness Evaluation Standard is based on the efficacy test method of the Fragrant Deodorant and Deodorant Association, and is set to "+4: Extremely Pleasant", "+3: Very Pleasant", "+2: Pleasant "," +1: Slightly unpleasant "," 0: No pleasant or unpleasant "," -1: Slightly unhappy "," -2: Unhappy "," -3: Very unhappy "," -4: Extremely unhappy " . The evaluation of the case where the odorous substance is not treated with aerosol after dispersing the odorous substance is -3. Table 1 shows the results (pleasure and unhappiness) of the deodorizing efficacy tests of Examples 4, 5 and Comparative Example 1.

As a result of the deodorizing efficacy test, Examples 4 and 5 were not evaluated below "+1: slightly pleasant" during the entire test period. Specifically, in the aerosol for deodorization of Example 4, the fragrance of citrus was confirmed from each time point after 0 minutes, 5 minutes, and 10 minutes after spraying. After 20 minutes of spraying, the system became fragrance-free, but the feces and urine simulated odorous systems were harmonized. After the aerosol for deodorization of Example 5 was sprayed to 5 minutes, the aroma of citrus was confirmed. After 10 minutes of spraying, the fragrance of the system gradually decreased, but the fecal urine simulated odor system was harmonized.

On the other hand, in the aerosol system for deodorization of Comparative Example 1, it was confirmed that the feces and urine smelled like odor after being sprayed for 0 minutes, and 5 minutes after being sprayed, the feces and urine simulated odor disappeared. However, after 10 minutes of spraying, the fecal simulated odor re-emerged, and thereafter, from 60 minutes of spraying, the fecal simulated odor gradually became stronger.

As described above, the aerosol systems for deodorization in Examples 4 and 5 of the product of the present invention exhibited superior deodorization effects on either side of the immediate effect and the durability compared to Comparative Example 1 on the market.

<Chemical deodorizing effect test> About the deodorizing aerosols of Examples 1 and 4, a chemical deodorizing effect test by a machine measurement method was performed. The test method is based on the deodorizing effect test method of the Association of Aromatic Deodorant and Deodorant Conventions. A 10-liter plastic container is filled with an odor component (ammonia), and after filling, an aerosol for deodorization is sprayed once. The ammonia concentration in the container was measured using a gas detection tube before spraying an aerosol for deodorization, after spraying for 1 hour, and after spraying for 10 hours. The following formulas were used to calculate the 1 hour after spraying and 10 hours after spraying. The respective decay rates. Attenuation rate (%) = 100- ｛Ammonia concentration after spraying (ppm) / Ammonia concentration before spraying (ppm)｝ × 100 The results (decay rate) of the chemical deodorizing efficacy tests in Examples 1 and 4 are shown in Table 2.

As a result of the chemical deodorizing effect test, in any of Examples 1 and 4, the attenuation rate after 1 hour of spraying was 60% or more, and the attenuation rate after 10 hours of spraying further increased to 87%. In this manner, the aerosol systems for deodorization of Examples 1 and 4 exhibited a continuous deodorizing effect from spraying to 10 hours. [Industrial availability]
