Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a deodorizing aerosol product and a method for producing the same.
[0002]
[Prior art]
Currently, there is a problem of bad odor as one of the environmental problems, and excrement and septics caused by the decay of organic matter such as human or animal life or food in various companies, homes, schools and other places. Various measures have been taken against odors from other odor-generating substances.
And it is known to use a fragrance, a deodorant, a deodorant, a deodorant, etc. as a countermeasure against odor in the living environment.
[0003]
A fragrance masks odor in a specific environment by releasing a fragrance into a space, and a deodorizer applies a substance that releases a specific fragrance. In addition, the deodorizer relieves the degree of odor by utilizing physical adsorption of odorous substances.
However, none of these treats the odor source material itself, and therefore the odor source remains as it is, so that it cannot be said to essentially solve the problem of odor.
[0004]
On the other hand, deodorizers remove or mitigate odors by decomposing and altering odor source substances by chemical action or biological action, and thus essentially solve the problem of odor. It is preferable.
Conventionally, it has been proposed to use various compounds and microorganisms in order to obtain a deodorizing effect.
[0005]
However, in living environments such as homes and schools, there is no known deodorant that is easy to use and has a deodorizing effect that is reliable and has no adverse effects on the applied environment. .
For example, certain microorganisms are known to exert a deodorizing action because their odor source substances are decomposed by their activities, but there are various limitations in using such a deodorizing microorganism. And conditions are necessary, and their management and application are actually quite difficult.
[0006]
[Problems to be solved by the invention]
The present invention has been made based on the circumstances as described above, and an object of the present invention is to provide a deodorizing aerosol product capable of obtaining a deodorizing effect by utilizing the activity of deodorant bacteria. It is in.
Another object of the present invention is to provide a method capable of advantageously producing a deodorant aerosol product utilizing a deodorant bacterium.
[0007]
[Means for Solving the Problems]
The deodorant aerosol product of the present invention comprises ion-exchanged water, living deodorant bacteria, and a lower aliphatic alcohol having 1 to 3 carbon atoms , and the concentration of the lower aliphatic alcohol. Is in a range of 0.5 to 15% by volume, and a stock solution containing no substance serving as a nutrient for the deodorant bacteria is filled in an aerosol container together with a propellant.
[0008]
In the above, the deodorant bacterium is a spore fungus mixed with three types of Bacillus subtilis, Bacillus megaterium, and Bacillus licheniformus. preferable.
[0009]
The stock solution preferably contains deodorant bacteria at a rate of 1 × 10 ⁴ to 1 × 10 ¹¹ per milliliter.
Furthermore, the propellant is preferably one or more selected from liquefied petroleum gas, dimethyl ether and compressed gas.
[0010]
The method for producing a deodorant aerosol product of the present invention comprises adding a lower aliphatic alcohol having 1 to 3 carbon atoms to ion-exchanged water containing living deodorant bacteria, to thereby produce the lower aliphatic. A step of preparing a stock solution in which the concentration of alcohol is within a range of 0.5 to 15% by volume and no substance serving as a nutrient for the deodorant bacteria exists , and this stock solution is filled in an aerosol container together with a propellant.

[0011]
[Action]
According to the deodorant aerosol product of the present invention, the deodorant bacterium contains ion-exchanged water and a lower aliphatic alcohol having 1 to 3 carbon atoms at a specific concentration in the aerosol container. Since it is present in a stock solution that does not contain any nutrients for odorous bacteria, it does not act actively as it is, and is therefore stable as a deodorizing aerosol product and has sufficient storage stability.
[0012]
In addition, when the stock solution is ejected from the aerosol container by the action of the propellant and applied to the odor source material, the lower aliphatic alcohol volatilizes in the atmosphere and the deodorant bacteria immediately start to act. The deodorizing effect by can be obtained reliably. And, for application of the undiluted solution, it is only necessary to spray it, so that the operation is very simple.
Accordingly, there is provided a deodorant that utilizes microorganisms called deodorant bacteria, but can be managed and applied very easily without the necessity of using a different meaning.
[0013]
Further, according to the method for producing a deodorant aerosol product of the present invention, by adding a lower aliphatic alcohol having 1 to 3 carbon atoms to ion-exchanged water that already contains deodorant bacteria , Since a stock solution containing a lower fatty alcohol at a specific concentration and containing no substances that serve as nutrients for the deodorant bacteria is prepared, the concentration of the lower aliphatic alcohol becomes high during the preparation of the stock solution. The desired stock solution can be prepared in a state where no situation occurs and therefore live deodorant bacteria are prevented from being damaged by the lower aliphatic alcohol, and thus the intended eradication An odor aerosol product can be reliably produced.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
The aerosol product for deodorization of the present invention is prepared by adding a lower aliphatic alcohol having 1 to 3 carbon atoms to ion-exchanged water containing deodorant bacteria, and this stock solution and an appropriate propellant are used. It is configured by filling a pressure-resistant aerosol container provided with an injection valve device.
[0015]
The stock solution is mainly composed of ion-exchanged water, which contains deodorant bacteria.
The deodorant bacteria used in the present invention are particularly limited as long as the compounds that become odor source substances are decomposed by the activity, and thereby the deodorizing effect can be obtained by exhibiting the deodorizing action. is not.
In practice, it is preferable to use bacteria belonging to spore bacteria.
[0016]
In the present invention, it is particularly preferable to use deodorant bacteria selected from the following (1) to (7).
(1) Arthrobacter
(2) Nocardia
(3) Mycobacterium
(4) Bacillus subtilis
(5) Bacillus megaterium
(6) Bacillus licheniformus
(7) Alcaligenes
[0017]
Although only one kind of the above deodorant bacteria may be used, it is preferable to use a plurality of kinds in a mixed state, so that the effective deodorization of a plurality of compounds constituting the odor source substance can be achieved. Odor effect is obtained. Depending on the type of deodorant bacteria, the type of odor source compound that effectively exerts the deodorant action differs, and multiple deodorant bacteria may coexist, resulting in a combined deodorant action. Because there are many.
[0018]
Specifically, among the above deodorant bacteria, (4) Bacillus subtilis, (5) Bacillus megaterium, and (6) Bacillus licheniformus are used in combination. The mixing ratio in this case is not limited, but the number is 25 to 40:25 to 40:25 to 40.
[0019]
Further, it is preferable to use a mixture of the Bacillus subtilis (4) and the Bacillus megaterium (5), and the mixing ratio in this case is not limited. 30-70: 30-70.
In particular, when used alone, (4) Bacillus subtilis is most preferable.
[0020]
In the stock solution containing ethyl alcohol described later, the deodorant bacteria are preferably contained at a rate of, for example, 1 × 10 ⁴ to 1 × 10 ¹¹ cells / ml, and actually 1 × 10 ⁵ to 1 The ratio is preferably 10 × 10 ⁹ pieces / milliliter, and particularly preferably 1 × 10 ⁶ to 1 × 10 ⁸ pieces / milliliter.
When the ratio of deodorant bacteria is less than 1 × 10 ⁴ cells / ml, there is a possibility that a sufficient deodorizing action cannot actually be obtained because the amount of activity by the deodorant bacteria is small. On the other hand, the state where the number of deodorant bacteria is 1 × 10 ¹¹ / ml is practically almost saturated, and the activity may not be sufficiently performed.
[0021]
The stock solution contains a lower aliphatic alcohol having 1 to 3 carbon atoms. Specific examples thereof include ethyl alcohol and isopropyl alcohol. The concentration of the lower aliphatic alcohol depends on the type of deodorant bacteria used, but is preferably in the range of 0.5 to 15% by volume and usually 1 to 5% by volume. It may be ˜3% by volume.
The concentration of the lower aliphatic alcohol needs to be 15% by volume or less, and if it exceeds 15% by volume, the deodorant bacteria present in the stock solution are likely to be killed. On the other hand, when the concentration of the lower aliphatic alcohol is too low, the germination suppressing effect of the deodorant bacteria due to the lower aliphatic alcohol necessary in the aerosol container may be insufficient, and the deodorant bacteria are already present. When germination and death have occurred, the degree of activity by the deodorant bacteria will be low when applied, so the desired deodorant effect cannot be obtained sufficiently There is.
[0022]
The deodorant bacteria are usually in the state of a bacterial stock solution containing the deodorant bacteria in a state of being saturated or nearly saturated (for example, contained at a rate of 1 × 10 ¹¹ cells / ml) in ion-exchanged water. Prepared and stored.
Then, such a bacterial stock solution is added to ion-exchanged water, and a stock solution is prepared by adding an amount of lower aliphatic alcohol having 1 to 3 carbon atoms in a predetermined concentration to the resulting bacterial dilution. Is done.
In the preparation of this stock solution, the reason why ion-exchanged water is used as an aqueous medium is that no nutrient for deodorant bacteria is contained.
[0023]
By preparing the stock solution by such a method, the environment where the deodorant bacteria are present does not become a state where the concentration of the lower aliphatic alcohol is high, and therefore, the deodorant bacteria are caused by the action of the lower aliphatic alcohol. Is reliably prevented from taking damage. As a result, the intended effect of the deodorant bacteria is surely exhibited.
In the above, as the ethyl alcohol, for example, denatured ethanol having a purity of 95% can be used.
[0024]
In the stock solution containing the deodorant bacteria of the present invention, if it does not impair the state of the deodorant bacteria, that is, the kind that does not damage the deodorant bacteria and does not promote germination and If it is in a range, various additive components can be contained.
Specific examples thereof include powders, fragrances, dyes, and the like. Although these additional components differ depending on the type, they can be usually added in an amount such that the total content in the stock solution is 10.0% by mass or less, preferably 1.0% by mass or less.
[0025]
The stock solution is filled in an aerosol container together with an appropriate propellant. The propellant is not particularly limited as long as it does not adversely affect the deodorant bacteria, and various types can be used, and specific examples include liquefied petroleum gas, dimethyl ether and compressed gas. be able to. Examples of the compressed gas include nitrogen gas, compressed air, argon gas, carbon dioxide gas, and the like. These propellants can be used alone or in combination of two or more. Among these, in the present invention, dimethyl ether or nitrogen gas is preferable as the propellant, and dimethyl ether is particularly preferable.
[0026]
The ratio of the stock solution and the propellant is not special, and for example, it may be a ratio at which the entire amount of the stock solution is reliably injected. Specifically, when the propellant is dimethyl ether, the stock solution is 50 to 90% by volume, preferably 60 to 80% by volume, and the propellant is 10 to 50% by volume depending on the proportion of the stock solution. , Preferably in the range of 20 to 40% by volume.
[0027]
The above stock solution and propellant are filled in an aerosol container. However, in the present invention, the aerosol container is not particularly limited, and those usually used for this kind of application can be used as they are.
[0028]
In the deodorant aerosol product configured as described above, since the medium containing the deodorant bacteria is ion-exchanged water in the aerosol container, there is a substance serving as a nutrient for the deodorant bacteria. In addition, since a lower aliphatic alcohol having 1 to 3 carbon atoms is contained, the deodorant bacteria are virtually prevented from causing germination and other activities, so to speak, a so-called dead state. It will be kept. Moreover, since the concentration of the lower aliphatic alcohol is limited, the deodorant bacteria are hardly damaged.
Accordingly, the deodorant aerosol product has high storage stability and the performance of the stock solution does not change over a long period of time.
[0029]
The reason why such a preferable state is maintained is that the container filled with the stock solution is an aerosol container and has a high hermetic sealability from the outside atmosphere. That is, the aerosol container reliably maintains the asphyxia state in which the activity of the deodorant bacteria is virtually stopped and does not die.
[0030]
In addition, this deodorant aerosol product is sprayed from an aerosol container by the action of a propellant.For example, when applied to an odor source material, the lower aliphatic alcohol in the undiluted solution immediately evaporates into the atmosphere. The cause of stopping the activity of the odorous bacteria disappears. Therefore, when the deodorant bacteria come into contact with the odor source substance, the activity is started immediately, and germination occurs and grows. As a result of the activity of such deodorant bacteria, the odor source material is decomposed and the odor disappears or is greatly reduced.
[0031]
As described above, according to the deodorant aerosol product of the present invention, while using a microorganism called deodorant bacteria, the conditions necessary for the storage or management of the deodorant bacteria are maintained in the aerosol container. Since it is sufficiently arranged, practically no work or precautions for storage or management are required, and a sufficiently long storage period can be obtained.
[0032]
In application, it is only necessary to operate the injection valve of the aerosol container to inject the stock solution as the contents and bring it into contact with the odor source material. The deodorization treatment can be performed in a short time, and the odor source can be produced without causing any harmful effects such as polluting the environment because the deodorizing action is exerted by microorganisms. The substance can be deodorized.
[0033]
The deodorant aerosol product of the present invention can be applied to any odor source material as long as the deodorant bacteria are effective. Therefore, it is also possible to select the type of deodorant bacteria to be used depending on the odor source material, and thereby, for example, a high deodorizing action can be exerted on a special odor source material.
[0034]
As can be understood from the above description, the deodorizing aerosol product of the present invention can be applied over a wide range, and is required to have a deodorizing effect in the living environment of homes, schools and other natural persons. For places and odor source substances, the present invention can be applied to the processing of garbage such as toilets, air conditioners and leftovers, animal breeding grounds, and other places where odors are generated.
In addition, the application method of the deodorant aerosol product of the present invention is not limited, and the deodorant aerosol product stock solution is applied to an appropriate carrier material in addition to the direct application to the odor source material. It is also possible to use a method of making a deodorizing member by applying it and placing it in an appropriate space or location so as to contact the odor source substance.
[0035]
〔Example〕
In deionized water, Bacillus subtilis, Bacillus megaterium, and Bacillus licheniformus are mixed evenly as deodorant bacteria, thereby containing deodorant bacteria at a rate of 1 × 10 ¹¹ cells / ml. A prepared bacterial stock solution was prepared.
Next, a bacterial dilution containing deodorant bacteria is prepared at a rate of 1 × 10 ⁹ cells / milliliter by adding this bacterial stock solution to ion-exchanged water. By gradually adding 95% denatured ethyl alcohol, a stock solution having an ethyl alcohol concentration of 2.5% by volume and containing deodorant bacteria at a rate of 1 × 10 ⁷ cells / ml was prepared.
The stock solution thus obtained and a propellant made of dimethyl ether are filled in a pressure-resistant aerosol container made of an aluminum can having a valve at a ratio of 65% by volume for the former and 35% by volume for the latter. Thus, the deodorizing aerosol product of the present invention was produced.
[0036]
[Experiment]
The following experiment was conducted using the above-described deodorizing aerosol product.
Put 1 liter of air in an airtight Tedlar bag with a capacity of 1 liter, add 36 microliters of an aqueous solution diluted with 30% by weight ammonia water 200 times, and vaporize it with a dryer to create ammonia-containing air. The ammonia concentration was measured.
A deodorant test piece is prepared by spraying the above deodorant aerosol product for 5 seconds on one side of a high-quality paper piece 9 cm long and 15 cm wide, and applying the stock solution. Immediately after filling in the Tedlar bag with the above-mentioned ammonia-containing air, the ammonia-filled air is filled with all the ammonia-containing air immediately after filling, and after 5 minutes, 10 minutes and 20 minutes. The survival rate was determined. The results are as shown by curve A in FIG.
[0037]
Further, in the preparation of the deodorant test piece, the same experiment as described above was performed, except that the injection time of the deodorant aerosol product was changed to 10 seconds and 20 seconds, and the ammonia residual rate was obtained. The respective results are as shown by curve B and curve C in FIG.
[0038]
In addition, except for using the same high-quality paper piece without applying the deodorizing aerosol product instead of the deodorizing test piece, an experiment similar to the above was performed to determine the ammonia residual rate. The result is as shown by curve D in FIG.
[0039]
From the above results, according to the deodorizing aerosol product of the present invention, it is clear that the deodorizing effect appears immediately after the deodorizing test piece comes into contact with the ammonia-containing air, and the effect is enhanced with the passage of time. In particular, it is understood that the effect is remarkable when a deodorizing test piece to which a large amount of stock solution is adhered is used.
[0040]
Further, after the deodorizing aerosol product produced in the same manner as described above was stored in an atmosphere of temperature 25 ° C. and atmospheric pressure for 3 months, an experiment similar to the above was conducted. It was confirmed that it was obtained.
From this, it was confirmed that the deodorizing aerosol product of the present invention has excellent storage stability, and the desired deodorizing action can be obtained even after long-term storage.
[0041]
【The invention's effect】
According to the deodorizing aerosol product of the present invention, the deodorizing bacteria are present in the ion-exchanged water containing the lower aliphatic alcohol having 1 to 3 carbon atoms in the aerosol container. Therefore, it is stable as a deodorizing aerosol product and has sufficient storage stability.
[0042]
Moreover, when the stock solution is ejected from the aerosol container by the action of the propellant and applied to the odor source material, the deodorant bacteria start to act immediately because the lower aliphatic alcohols volatilize in the atmosphere, so the deodorant bacteria The deodorizing effect by can be obtained reliably. And, for application of the undiluted solution, it is only necessary to spray it, so that the operation is very simple.
Accordingly, there is provided a deodorant that utilizes microorganisms called deodorant bacteria, but can be managed and applied very easily without the necessity of using a different meaning.
[0043]
In addition, according to the method for producing a deodorant aerosol product of the present invention, a stock solution is obtained by adding a lower aliphatic alcohol having 1 to 3 carbon atoms to ion-exchanged water already containing deodorant bacteria. Therefore, there is no situation where the concentration of ethyl alcohol becomes high in the process of preparing the stock solution, and therefore, the living deodorant bacteria are prevented from being damaged by the lower aliphatic alcohol. The intended stock solution can be prepared, and thus the intended deodorizing aerosol product can be reliably produced.
