Description

Deodorizing Aerosols

The present invention relates to an aerosol for deodorization excellent in the immediate effect and the sustainability of the deodorizing effect.

As a product for deodorizing the odor of the toilet space, a deodorant containing a deodorant component is commercially available. As the deodorant for toilet spaces, various kinds of deodorants are known, such as a stationary type in which a deodorant effect is continuously obtained by standing in the room and volatilizing the deodorant component, and a spray type in which the deodorant component is sprayed into the room by a spray. Deodorizing aerosols are known as being suitable for applications requiring immediate effectiveness such as deodorizing odor after stool or deodorizing toilets with strong odors in outbound areas.

Patent Literature 1 rapidly disperses a fragrance of a fragrance after deodorization while obtaining a deodorizing effect by rapidly dispersing a drug particle of a sufficient amount of fragrance into a processing space and masking a malodor remaining in the air with the fragrance of the fragrance. Deodorizing aerosols are disclosed.

International Publication No. 2017/073478

However, as in Patent Literature 1, a method of rapidly dispersing drug particles into a processing space and then promptly losing the fragrance of the fragrance may not sufficiently exert a deodorant effect on the odor that is continuously generated, and consequently deodorization. May become incomplete. However, since a toilet in a general house or the like has a narrow space of about 2.5 to 3.5 m 3, increasing the amount of drug particles released to the treatment space makes the user in the treatment space feel strongly the direction of the drug particles. In particular, there is a fear of discomfort to consumers who do not like strong directions.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a deodorizing aerosol capable of exhibiting a deodorizing effect excellent in instantaneous and sustained in a treatment space such as a toilet.

Characteristic configuration of the deodorizing aerosol according to the present invention for solving the above problems,

An internal pressure vessel provided with an aerosol stock solution containing a deodorizing component and an organic solvent, and a metered injection valve formed by encapsulating a propellant;

An injection button having an injection hole connected to the metered injection valve

As a deodorant aerosol containing,

When the injection button is pressed once, the injection capacity is adjusted to 0.1 to 0.4 mL, and the injection force at an injection distance of 20 cm is adjusted to 0.3 to 10.0 g · f at 25 ° C.,

When the aerosol stock solution in the pressure-resistant container is injected into the processing space of 2.5 to 3.5 m 3 by pressing the spray button once, at least 50% by volume of the injected aerosol stock solution adheres to the exposed portion in the processing space within 60 minutes. It is comprised so that an adhesive particle may be formed.

The odor in the toilet is not only staying in the air of the treatment space, but also continues to be generated from odor sources such as urine scattered on the wall, floor, or the like. The present inventors considered that enhancing the deodorant effect on the odor generated from the odor source attached to the wall surface or the like leads to the improvement of the deodorant effect on the odor in the bathroom. Therefore, in the deodorizing aerosol according to the present invention, at least 50% by volume of the aerosol stock solution injected into the processing space forms adhesive particles. An adhesive particle is an exposed part in a processing space (for example, the floor which exists in a toilet space within 60 minutes after spraying) among the injection particles formed when the aerosol stock solution is injected into a processing space of 2.5-3.5m <3> from a deodorizing aerosol. Particles attached to a surface, a wall, or a surface of a structure such as a toilet. Therefore, both the odor generated from the odor source attached to the exposed portion and the odor remaining in the air of the processing space can be effectively deodorized, and the deodorizing effect of the entire processing space can be improved. In addition, even when spray particles other than the adherent particles (called "floating particles") diffuse to every corner of the treatment space, the concentration of the aerosol stock solution in the treatment space is reduced only in the adhesion particles. Therefore, the amount of inhalation of particles of the aerosol stock solution by the user in the processing space becomes extremely small, and it is possible to suppress the excessive direction from the aerosol stock solution itself. In addition, the deodorizing aerosol according to the present invention is adjusted so that the injection capacity when the injection button is pressed once is 0.1 to 0.4 mL, and the injection force at an injection distance of 20 cm is 0.3 to 10.0 g · f at 25 ° C.

In the deodorizing aerosol according to the present invention,

It is preferable that 90% particle diameters in the volume integration distribution in 25 degreeC and 15 cm of injection distances of the injection particle formed when the said injection button is injected and the said aerosol stock solution in the said pressure-resistant container are preferable are 40-60 micrometers.

By adjusting the particle diameter of spray particle | grains to the said optimal range, one part of spray particle becomes adhesive particle, and the other becomes floating particle. Therefore, according to the deodorizing aerosol of this structure, both the odor which floats in the air of a process space, and the odor which arises from the odor source adhering to an exposed part can be deodorized.

In the deodorizing aerosol according to the present invention,

It is preferable that the capacity ratio (a / b) of the aerosol stock solution (a) and the propellant (b) enclosed in the pressure-resistant container is 10/90 to 50/50.

As a result, the adherent particles can reliably reach the exposed portion in the processing space, and the floating particles can float in the processing space in an amount that does not cause discomfort by the excessive direction. In this way, the adherent particles and the suspended particles are present in an optimal state, and each of the roles can be shared to maximize the effect of the deodorant component.

In the deodorizing aerosol according to the present invention,

It is preferable that the said organic solvent is at least 1 sort (s) chosen from the group which consists of higher fatty acid ester and alcohols.

According to the deodorizing aerosol of this structure, the effect of each component can be exhibited efficiently by using a higher fatty acid ester or alcohol as an organic solvent. In addition, when spraying the aerosol stock solution, the adherent particles and the floating particles can be formed in a good balance, and the deodorizing effect is stabilized.

In the deodorizing aerosol according to the present invention,

The deodorant component preferably includes a plant extract and a harmonized flavoring agent.

According to the deodorizing aerosol of this structure, a harmonized fragrance is harmonized with odors, such as a manure odor in a restroom, and the effect of the sensory deodorization which makes a smell smell good can be acquired.

In the deodorizing aerosol according to the present invention,

It is preferable that the said injection hole has the diameter of a partition of 0.2-1.0 mm.

According to the deodorizing aerosol of this structure, when the fractionation diameter is the said range, the balance of the adherent particle | grains and floating particle | grains formed from the aerosol stock solution injected is more optimized.

In the deodorizing aerosol according to the present invention,

It is preferable that the aerosol undiluted solution further contains blue-green alcohol and / or blue-green aldehyde.

Can be.

In the deodorizing aerosol according to the present invention,

The injected aerosol stock solution is preferably diffused into the entire processing space until 120 seconds later.

Formable particles can be formed.

In the deodorizing aerosol according to the present invention,

Preferably, the treatment space is a toilet.

According to the deodorizing aerosol of this structure, adherent particles adhere to exposed parts such as the wall, floor, and toilet of a restroom, so that a continuous deodorant effect can be obtained against odor generated from the odor source attached to the exposed part. have.

BRIEF DESCRIPTION OF THE DRAWINGS It is explanatory drawing of the diffusion simulation when the deodorizing aerosol which concerns on this invention was sprayed into 3m <3> of processing spaces.

The deodorizing aerosol of the present invention includes an aerosol stock solution containing a deodorizing component and an organic solvent, a pressure-resistant container provided with a metered injection valve formed by encapsulating a propellant, and an injection button having an injection port connected to the metered injection valve, When spraying the aerosol stock solution in the pressure-resistant container by pressing the spray button, 50% by volume or more of the injected aerosol stock solution can be formed as adherent particles. Adhesive particles are spray particles that adhere to the exposed portion in the processing space within 60 minutes after the injection, among the spray particles formed when the aerosol stock solution is injected into the processing space of 2.5 to 3.5 m 3 from the deodorizing aerosol. EMBODIMENT OF THE INVENTION Hereinafter, the deodorizing aerosol of this invention is demonstrated. However, this invention is not intended to be limited to the structure described in embodiment described below or drawing.

Aerosol Stock Solution

[Deodorant Ingredients]

It is preferable that the deodorant component which is one main component of an aerosol stock solution contains a vegetable deodorant component and a harmonized perfume. The vegetable deodorant component causes a so-called chemical deodorizing effect of reacting with a malodorous odorous substance to deodorize the odor. As such vegetable deodorant components, extracts of Forsythia viridissima, Ginkgo biloba, Fig tree and the like are preferably selected. These vegetable deodorant components can be used either alone or in a mixed state. In particular, it is preferable to use what is neutralized by reacting with any of an acidic gas and an alkaline gas as a vegetable deodorant component. Or you may mix and use the vegetable deodorant component which neutralizes acidic gas, and the vegetable deodorant component which neutralizes alkaline gas.

Harmonized flavorings are flavored perfumes which are intended to be converted into a good odor (scent) by taking odors such as manure odor as one of the fragrance components. Therefore, the harmonized fragrance causes a sensory deodorizing effect of being perceived as a good fragrance to humans by smelling it in an environment where one malodor is present as one of the fragrance components. Hereinafter, it is expressed that odor is harmonized that the unpleasant feeling by a odor is alleviated by a sensory deodorizing effect.

[Organic Solvent]

The organic solvent, which is another main component of the aerosol stock solution, can dissolve the deodorant component to prepare the aerosol stock solution, and can also form the optimum particles when the prepared aerosol stock solution is injected into the treatment space. do. As the organic solvent, higher fatty acid esters and alcohols are preferable. As higher fatty acid ester, it is preferable that carbon number is 16-20 total, For example, isopropyl myristic acid, butyl myristic acid, hexyl laurate, isopropyl palmitate, etc. are mentioned. Of these, myristic acid isopropyl is particularly suitable. As alcohol, C2-C3 lower alcohol is preferable, and ethanol, isopropanol, propanol is mentioned, for example. Of these, ethanol is particularly suitable. In the organic solvent, for example, hydrocarbon solvents such as n-paraffin and isoparaffin, glycol ethers having 3 to 6 carbon atoms, ketone solvents, and the like may be mixed.

[Other Ingredients]

In addition to the above components, the deodorizing aerosol of the present invention may be appropriately blended with aerosol stock solutions such as fragrances, antibacterial agents, fungicides, stabilizers, antistatic agents, antifoaming agents, excipients, and the like for fragrances, molds and fungi. You may. For example, when aerosol stock solution contains a fragrance, the odor floating in a process space by the fragrance of a fragrance can be masked. Examples of fragrances include orange oil, lemon oil, lavender oil, peppermint oil, eucalyptus oil, citronella oil, lime oil, citron oil, jasmine oil, hinoki oil, green tea essential oil, limonene, α-pinene, linalul, geraniol , Aromatic components such as phenylethyl alcohol, amylcinnamicaldehyde, cuminaldehyde, benzyl acetate, and fragrant components such as cis-3-hexenol and green leaf aldehyde combinations called "green leaf volatiles." Can be mentioned. By mixing the fragrance with the aerosol stock solution such as citrus, rose, and lavender, the palatability of the consumer can be satisfied. In addition, when the deodorizing aerosol is injected into the toilet by the combination of the blue-green alcohol, in which relaxation effects such as fatigue and stress are expected, the toilet can be made a more comfortable space. As a fungicide, an antibacterial agent, and a bactericide, a hinokithiol, 2-mercaptobenzothiazole, 2- (4-thiazolyl) benzimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, tri Porin, 3-methyl-4-isopropylphenol, ortho-phenylphenol, and the like.

<Injector>

Examples of the propellant used in the deodorizing aerosol of the present invention include liquefied petroleum gas (LPG), dimethyl ether (DME), nitrogen gas, carbon dioxide, nitrous oxide, and compressed air. Although the above propellants can be used alone or in a mixed state, those containing LPG as a main component are easy to use.

The deodorizing aerosol of this invention is adjusted so that the capacity ratio (a / b) of an aerosol stock solution (a) and propellant (b) may be 10 / 90-50 / 50. By adjusting to such a range, at least one part of the injected aerosol stock solution can be formed as adhesive particle. As a result, the adherent particles can reliably reach the exposed portion in the processing space, and the floating particles can float in the processing space in an amount that does not cause discomfort by the excessive direction. In addition, when both the adherent particles and the floating particles are formed, the balance of both is optimal. As described above, the adherent particles and the suspended particles are present in an optimal state, and each of the adhesive particles and the floating particles can be exerted to maximize the deodorizing effect. When the capacity ratio (a / b) is made smaller than 10/90, that is, the ratio of the propellant (b) enclosed in the pressure-resistant container is increased, the aerosol stock solution to be injected becomes finer than necessary, so that the adherent particles are reduced. Thereby, since the adhesive particle adhering to the exposed part in a process space is lacking, the odor which generate | occur | produces continuously from the odor source adhering to an exposed part cannot fully be deodorized, and the persistence of a deodorizing effect may be insufficient. On the other hand, when the volume ratio (a / b) is larger than 50/50, that is, when the ratio of the propellant (b) enclosed in the pressure-resistant container is reduced, the adherent particles having the particle diameter in the optimum range for the aerosol stock solution to be injected are And since it becomes difficult to form as floating particle | grains, an aerosol stock solution will precipitate immediately after spraying. Therefore, it becomes difficult to quantitatively lack the floating particles floating in the processing space and to quickly deodorize the odor.

<Deodorization aerosol>

As mentioned above, an aerosol product is completed by selecting a deodorizing component, an organic solvent, a propellant, and other components mix | blended as needed, and sealing them in a pressure-resistant container. This aerosol product is the deodorizing aerosol of the present invention, which injects the aerosol stock solution into the treatment space. The aerosol stock solution mainly consists of a deodorant component and an organic solvent, and is strictly different from a propellant. However, since the aerosol stock solution is discharged to the outside of the pressure-resistant container at the same time as the propellant, the aerosol stock solution and the propellant will be described later. The aerosol content containing may be treated as "aerosol undiluted solution".

Here, the injection valve which the deodorizing aerosol which concerns on this invention contains is demonstrated. The deodorizing aerosol according to the present invention mainly comprises a pressure-resistant container (aerosol container), a metering injection valve, and an injection button. The injection button which is an operation | movement part for injecting aerosol stock solution is connected to the fixed volume injection valve, and the injection button is provided with the injection port which ejects aerosol stock solution from an aerosol container to the exterior (process space).

When the injection button of the deodorizing aerosol is pressed once, the fixed-quantity injection valve is operated by the pressure of the propellant, the aerosol stock solution in the pressure-resistant container rises to the injection port, and is injected into the processing space. The injection capacity of the aerosol stock solution at this time is adjusted to 0.1 to 0.4 mL, more preferably to 0.2 to 0.4 mL. Within such a range, at least part of the aerosol stock solution is formed as adherent particles. In addition, in the case where both of the adherent particles and the suspended particles are formed, each of them is formed in a good balance so that the deodorizing effect can be optimally exhibited in the processing space. If the injection capacity is less than 0.1 mL, the injection capacity is too small, so that the adherent particles are not sufficiently adhered to the exposed portion in the processing space, and it is difficult to deodorize the odor generated continuously from the odor source attached to the exposed portion. do. In addition, since there are less floating particles, deodorization against odors floating in the air in the processing space is also insufficient. On the other hand, if the injection capacity exceeds 0.4 mL, since the aerosol stock solution is released into the processing space more than necessary, there is a risk of discomfort to consumers who do not like strong directions, and also because the amount of the aerosol stock solution is excessively used, economically, It is disadvantageous.

The deodorizing aerosol is adjusted so that the injection force at a place where the distance from the injection port is 20 cm is 0.3 to 10.0 g · f at 25 ° C. If it is such a range, by single injection, the adhesive particle formed from aerosol stock solution can be reached smoothly in the exposed part in a process space, and the effect of a deodorizing component can be exhibited quickly. Moreover, it is preferable to set the splitter diameter of the injection hole to 0.2-1.0 mm. If it is this range, it can adjust suitably by said particle diameter and injection force, and at least one part of the aerosol stock solution sprayed in the process space is optimally formed as adhesive particle, and it produces continuously from the bad smell source adhering to an exposed part. Odor can be deodorized.

It is preferable that the 90-% particle diameter in the cumulative volume distribution in 25 degreeC and 15 cm of spraying distances of the particle diameter of the injection particle sprayed from a deodorizing aerosol is adjusted to 40-60 micrometers. Within such a range, when the aerosol stock solution is injected into the treatment space of 2.5 to 3.5 m 3, at least 50% by volume of the injected aerosol stock solution can be formed as the adherent particles, and a sufficient amount of the adherent particles can be quickly processed. It can be moved to an exposed portion in the interior and attached. Therefore, the odor continuously generated from the odor source adhering to the exposed portion can be deodorized by the deodorant component of the adherent particles. If the particle diameter of the sprayed particles is less than 40 µm at 90% particle diameter in the integrated volume distribution at 25 ° C and the spraying distance 15cm, the particle diameter is too small, and it is difficult for many particles to reach the exposed portion, A sufficient amount of adherent particles is not formed. As a result, it becomes difficult to effectively deodorize the odor generated continuously from the odor source attached to the exposed portion. On the other hand, when the particle diameter exceeds 60 µm, the particle diameter is too large, making it difficult to control the behavior of the adherent particles, making it difficult to appropriately attach the exposed portion.

Moreover, as for the particle diameter of spray particle | grains, it is more preferable that 10% particle diameters are 5 micrometers or less and 50% particle diameters are adjusted to 20-40 micrometers in the integrated volume distribution in 25 degreeC and 15 cm of spray distances. The spray particles having such an integrated volume distribution have a wide distribution width of the particle diameter. As a result, once the aerosol stock solution is injected into the processing space from the deodorizing aerosol, adherent particles having a relatively large particle diameter and floating particles having a relatively small particle diameter are formed.

Since the floating particles are formed as smaller particle diameters than the adherent particles, when the aerosol stock solution is injected into the processing space, they can diffuse rapidly and float in the processing space. Therefore, the odor remaining in the air in the processing space can be deodorized by the deodorant component of the floating particles. In this way, by adjusting the particle diameter to the optimum range as described above, so that some of the injected aerosol stock solution forms floating particles, the floating particles exhibit different behavior from the adherent particles, together with the adherent particles. It can effectively deodorize odors.

Diffusion Simulation

BRIEF DESCRIPTION OF THE DRAWINGS It is explanatory drawing of the diffusion simulation when the deodorizing aerosol which concerns on this invention was sprayed into 3m <3> of processing spaces. The analysis method of the chemical | medical agent concentration used for the diffusion simulation of FIG. 1 is demonstrated below.

In analyzing the drug concentration, the situation in which the drug (aerosol undiluted solution) diffused with time was outputted as an analysis result. First, the airflow calculating means analyzes the spatial distribution such as the wind speed and the temperature until it reaches a steady state, and then generates a drug from the aerosol product, and uses the analyzed wind speed distribution and the like to calculate the concentration. The spatial distribution of drug concentration was predicted by normal analysis. In addition, the change by the time of concentration distribution was predicted by the abnormality analysis.

In the simulation space, the airflow calculating means discretizes and numerically solves a three-dimensional, two-flow advection diffusion equation by a finite difference method, thereby determining the velocity of the airflow, the direction of the airflow (wind speed, wind direction), and the temperature of the air ( Hereinafter, it may be called "the airflow state." The airflow calculation means is a k-ε turbulence model based on the Navier-Stokes equations (variables of the velocity and direction of the airflow and the pressure-dependent kinetic elements) (the transport equation of momentum, the turbulent flow). The advection consisting of the transport equation (2) of energy and the transport equation (3) of the turbulent dissipation rate), the transport equation of calories (4), and the continuous equations (5) to (8). Regarding the diffusion equation, iterative calculation is performed by using a numerical analysis by a finite difference method for each minute time between adjacent grid points of each minute division region, and the wind speed, wind direction, air temperature, and wind pressure between the grid points are equal to a predetermined equilibrium. In the case of a state, it is comprised so that it may be determined as the predicted wind speed data, the predicted wind direction data, and the predicted air temperature data of each said grid point as the value.

The concentration calculation means relates to a drug of interest in a simulation space, and is a means for obtaining a concentration distribution by discretizing and numerically solving a three-dimensional concentration diffusion governing equation by a finite difference method. In other words, the concentration calculating means calculates a chemical agent (diffusion) when the air flow conditions (predicted wind speed data, predicted wind direction data, and predicted temperature data) at the grid points in the calculated microdivision region are given, and the amount of generation of the diffusion substance is given. Regarding the concentration diffusion governing equation composed of the transport equation (9) of the material), iterative calculation is performed by using a numerical analysis by a finite difference method for each minute time between adjacent lattice points of each minute division region. When the chemical | medical agent density | concentration between points becomes equilibrium, it is comprised so that it can determine as a normal solution of the predicted chemical | medical agent concentration data of each said grid point by the value. Further, in the process of performing the iteration, it is also possible to determine the abnormal solution of the predicted drug concentration data by recording the accumulated value of the micro time and the drug concentration of each micro-divided area at that time for each predetermined time. In addition, by making the generation amount of a diffusion substance into a dimensionless amount, it is also possible to predict the predicted drug concentration data as a relative value corresponding to the generation amount of the diffusion substance instead of the absolute value.

The analysis target is for deodorizing the user 2 and the injection port 1a obliquely upward in a processing space of about 3 m 3 (78 cm in width x 169 cm in depth x 230 cm in height) as shown in FIG. The analysis shape which arrange | positioned the aerosol 1 was set. This analysis shape and processing space were divided into analysis grids.

The analysis conditions were set to the wind speed of 0 m / sec, and the influence of heat generation and temperature outside the room was ignored. From the injection port 1a of the deodorizing aerosol 1, the injection force at a distance of 0.2 mL per stroke and a 20 cm distance from the injection port was set at 2.9 g · f at 25 ° C to inject the aerosol stock solution, The spatial distribution of the air concentration of the aerosol stock solution was analyzed.

FIG. 1 (b) shows the air of the aerosol stock solution after 10 seconds, 30 seconds, 60 seconds, 120 seconds and 170 seconds after spraying the aerosol stock solution into the treatment space once from the deodorizing aerosol (1). It is an image of the result of diffusion simulation showing the concentration (ppm). In (b) of FIG. 1, the reference | standard A is attached | subjected to the area | region where the air concentration of the aerosol stock solution is 0.0007 ppm in each image. According to the above analysis, as shown in FIG. 1B, after the injection, the aerosol stock solution rapidly diffuses, after 60 seconds from the injection, reaches from the ceiling to the bottom of the processing space, and 120 seconds from the injection. Afterwards, a result of diffusion proceeding throughout the processing space was obtained. Here, "diffusion to the whole processing space" is a state in which the air concentration of the aerosol stock solution becomes 0.0007 ppm or more at a capacity of 95% or more of the processing space as shown in the image after 120 seconds in FIG. In addition, since the normal toilet use time of a person is about 5 to 15 minutes, if the diffusion time of the aerosol stock solution to the whole toilet space is 120 second, deodorization can fully be performed within the toilet use time. Further, after 170 seconds from the injection, the diffusion is continued until the concentration of the aerosol stock solution in the entire processing space becomes uniform. Therefore, when sufficient time has elapsed after spraying, the adherent particles are finished to adhere to all surfaces of the wall, bottom and ceiling surfaces in the processing space, and remain attached. As described above, the odor continuously generated from the odor source adhering to the exposed portion is deodorized by the deodorant component.

On the other hand, the floating particle gradually volatilizes a deodorant component and deodorizes the odor remaining in the air of the processing space. In particular, the odor in the bathroom includes urine odor due to ammonia, and dung smell due to hydrogen sulfide, methyl mercaptan, and the like. It tends to stay near the bottom surface. However, as shown in FIG. 1 (b), the aerosol stock solution injected from the deodorizing aerosol 1 diffuses to every corner of the entire processing space until 120 seconds after the injection, and thus the odor and floor surface remaining near the ceiling. All of the malodors remaining in the vicinity can be deodorized by the suspended particles. And ammonia is an alkaline gas, and hydrogen sulfide and methyl mercaptan are acidic gases. Since the aerosol stock solution contains a deodorant component capable of reacting with and neutralizing any of an alkaline gas and an acidic gas, any kind of odorous substance can be deodorized by chemical deodorization. The deodorizing component may be a mixture of a vegetable deodorizing component capable of reacting with an alkaline gas and neutralizing it, and a mixture of a vegetable deodorizing component capable of reacting with an acidic gas and neutralizing it, or reacting with an alkaline gas and an acidic gas to neutralize it. Preference is given to using vegetable deodorant components.

As described above, the deodorizing aerosol according to the present invention has two kinds of particles having different behaviors from the particles formed by the injected aerosol stock solution, so that each particle exists in an optimal state, and the respective roles are shared to provide a deodorizing effect. It can be exercised as much as possible. Therefore, the adherent particles and the floating particles can exhibit excellent deodorizing effects in either of the odor remaining in the air in the processing space and the odor generated from the odor source attached to the exposed portion in the processing space.

And as an analysis condition, when setting injection volume and injection force smaller than the diffusion simulation shown in FIG. 1, for example, the injection force at the distance of 0.1 mL and 20 cm from an injection port is 0.4 g at 25 degreeC, for example. In the model set to f, similarly to the diffusion simulation shown in FIG. 1, the results of the diffusion simulation that the aerosol stock solution rapidly diffused through the entire processing space were obtained. When setting the injection capacity and the injection force larger than the diffusion simulation shown in FIG. 1, for example, the model which sets the injection force at the distance of 0.4 mL and a 20 cm distance from the injection port to 7.0 g * f at 25 degreeC, for example. In the same manner as in the diffusion simulation shown in FIG. 1, a result of the diffusion simulation in which the aerosol stock solution rapidly diffused into the entire processing space was obtained.

As described above, by injecting the aerosol stock solution into the treatment space of 2.5 to 3.5 m 3 once from the deodorizing aerosol according to the present invention, a deodorizing effect excellent in immediate efficacy and durability is obtained. The space of 2.5-3.5 m <3> is approximately corresponded to the size of the toilet space (80-85 cm in width X 140-180 cm in depth X 230 cm in ceiling height) of a general house. Therefore, if it is the deodorizing aerosol which concerns on this invention, a deodorant can be deodorized quickly in a general restroom etc. and the deodorizing effect can be continued for a long time. Further, some of the particles formed by the aerosol stock solution injected into the treatment space from the deodorizing aerosol according to the present invention are formed as floating particles. Therefore, the concentration of the aerosol stock solution (floating particles) diffused in the processing space is reduced by the adherent particles, and the concentration of the processing space is low. Therefore, the direction from a floating particle can be reduced and it can suppress that an unpleasant feeling is made to a consumer who does not like a strong direction.

<Example>

<Injection force, measurement of particle diameter>

The deodorizing aerosol (Examples 1-3) provided with the characteristic structure of this invention was prepared, and injection force was measured. Moreover, the particle diameter of the spray particle | grains was measured about the aerosol for deodorization of Example 1. The aerosol stock solution of the deodorizing aerosol is mixed with a balance (balance) of 1.35 g (10 w / V%) of plant extracts, 0.4 g (3 w / V%) of harmonized flavors, and ethanol (anhydrous) as an organic solvent. And the total amount was prepared at 13.5 mL.

<Deodorant effect test>

In order to confirm the deodorizing effect of the deodorizing aerosol of the present invention, a deodorizing aerosol (Examples 4 and 5) prepared in the same manner as in Example 1 was prepared, and the deodorizing effect test was performed by olfactory measurement. . In addition, for comparison, a deodorizing aerosol (Comparative Example 1) different from the present invention was prepared, and the same deodorizing efficacy test was performed.

A deodorizing aerosol was produced from the same raw materials and manufacturing methods as those for the deodorizing aerosol of Example 1, except that a trace amount of citrus fragrance was blended into the aerosol stock solution, and this was referred to as example 4. The deodorizing aerosol was produced by the same raw materials and manufacturing methods as the deodorizing aerosol of Example 1, except that a small amount of orange perfume was added to the aerosol stock solution as a perfume.

In Comparative Example 1, a commercially available deodorizing aerosol containing a fatty acid salt as a deodorizing component, a quaternary ammonium salt as a sterilizing component, and ethanol as an organic solvent was used.

In the deodorizing effect test, a predetermined amount of odorous substance showing a manure simulated odor was sprayed in a processing space of 3 m 3. Thereafter, the deodorizing aerosol is sprayed once in the treatment space, and immediately after the spraying (after 0 minutes), after 5 minutes, after 10 minutes, after 20 minutes, after 30 minutes and after 60 minutes, the odor in the treatment space is paneled. The list was evaluated by the nine-stage comfort and discomfort notation. However, since the deodorizing aerosol of the comparative example 1 is an aerosol product without a fixed-quantity injection valve, it switched to the one-time fixed injection and performed continuous injection for 1 second according to the usage of the comparative example 1. The injection amount measured the deodorizing aerosol before and after injection, and calculated | required from the weight difference.

Evaluation criteria of the nine-stage comfort and unpleasantness indication method are based on the test method of the aroma deodorant deodorant council, "+4: extremely pleasant", "+3: very pleasant", "+2: pleasant", "+ 1: somewhat pleasant "," 0: neither comfortable nor unpleasant "," -1: somewhat unpleasant "," -2: unpleasant "," -3: very unpleasant "," -4: extremely unpleasant ". After spraying a odor substance, the evaluation in the case of untreated deodorant aerosol was -3. Table 1 shows the results (delight, unpleasantness) of the deodorant efficacy test in Example 4, Example 5, and Comparative Example 1.

TABLE 1

As a result of the deodorant potency test, neither of Examples 4 and 5 was below the evaluation of "+1: somewhat comfortable" in the entire test period. Specifically, in the deodorizing aerosol of Example 4, the directions of citrus fruits were confirmed at each time point 0 minutes, 5 minutes, and 10 minutes after the injection. After 20 minutes from the injection, the aroma disappeared, but the smell of the manure mock was harmonized. In the aerosol for deodorization of Example 5, the direction of orange was confirmed until 5 minutes after injection. After 10 minutes from the injection, the fragrance gradually decreased, but the smell of the manure hair was harmonized.

On the other hand, in the deodorizing aerosol of Comparative Example 1, the smell of the manure mock was confirmed 0 minutes after the injection, and the smell of the manure mock was lost 5 minutes after the injection. However, after 10 minutes of injection, the manure scent was again produced, and then the manure scent became gradually stronger until 60 minutes after the injection.

Thus, the aerosol for deodorization of Example 4 and Example 5 which is this invention showed the deodorizing effect excellent in any of immediate effect and persistence compared with the comparative example 1 which is a commercial item.

<Chemical Deodorization Effect Test>

About the deodorizing aerosol of Example 1 and Example 4, the chemical deodorization efficacy test by the instrument measuring method was done. The test method inject | poured and filled with the deodorant component (ammonia) in a 10-L plastic container based on the deodorization efficacy test method of the deodorant deodorant meeting, and sprayed deodorant aerosol once. The ammonia concentration in the vessel was measured using a gas detector tube before deodorizing aerosol injection, 1 hour after injection, and 10 hours after injection, and the respective attenuation rates after 1 hour and 10 hours after injection were calculated by the following equation.

Attenuation Ratio (%) = 100-{Ammonia concentration after spraying (ppm) / Ammonia concentration before spraying (ppm)} × 100

Table 2 shows the results (damping ratios) of the chemical deodorizing efficacy tests in Examples 1 and 4.

TABLE 2

As a result of the chemical deodorant efficacy test, in either of Examples 1 and 4, the damping rate after 1 hour of injection was 60% or more, and the damping rate after 10 hours of injection was further increased to 87%. Thus, the deodorizing aerosols of Examples 1 and 4 showed a continuous deodorizing effect over 10 hours from the injection.
