Description

The present invention relates to a sleep environment improvement method for improving the environment from the sleep preparation stage before sleep to during sleep and immediately after waking up.

For example, in the case of a patient with hay fever, an allergic reaction may occur by inhaling a predetermined amount or more of pollen. It is also known that dead mites and feces can cause allergic reactions.

For example, Patent Document 1 discloses an anti-allergen composition containing an aluminum salt and a water-soluble polymer for imparting water resistance, and the anti-allergen composition is sprayed on a textile product or the like. I try to spray it.

Further, Patent Document 2 discloses an allergen neutralizing composition, in which a film-forming polymer such as polyacrylic acid contained in the allergen neutralizing composition is sprayed on a cloth to immobilize dust particles containing the allergen. I try to do it.

Japanese Unexamined Patent Publication No. 2008-94906 Japanese Patent Publication No. 2004-510841

By the way, even if the amount of sleep is sufficient, it may be felt that the person is not tired after sleeping. In such a case, the quality of sleep may be poor. In addition, in the case of hay fever patients and allergic patients, it may be difficult to fall asleep due to runny nose or sneezing in the preparatory stage before sleep, and even during sleep, sleep is light due to the influence of runny nose. They can be prone and these are thought to cause poor sleep quality.

In addition, a so-called morning attack may occur, in which a person suddenly sneezes continuously immediately after waking up, has a stuffy nose, or has a runny nose. Although the cause is not clear, it is thought that one of the causes is due to the above-mentioned allergens. It is possible that humans have inhaled the allergen and the symptoms of morning attack have developed. Furthermore, it is considered that the odor of bedding and the like also affect the quality of sleep.

As described above, the sleeping environment may be deteriorated due to various causes from the sleep preparation stage before sleep to during sleep and immediately after waking up, and there is a demand to improve such sleeping environment as much as possible.

Therefore, for example, it is conceivable to spray the bedding with an anti-allergen composition or an allergen neutralizing composition as disclosed in Patent Documents 1 and 2. In Patent Document 2, it is considered that the allergen can be aggregated by using a flocculant such as polyacrylate, but even if the allergen can be aggregated by the flocculant, an allergic reaction occurs when the allergen is in an active state. Therefore, it becomes meaningless unless the deactivating effect of the allergen is sufficiently enhanced along with the aggregation.

On the other hand, Patent Document 1 contains an aluminum salt or the like as an allergen inactivating agent and a water-soluble polymer for imparting water resistance. However, according to the studies by the inventors of the present application, the allergen inactivating effect of the aluminum salt or the like requires the presence of water around it. On the other hand, if the bedding or the like is damp at bedtime, it is uncomfortable, so it needs to be dry. However, in Patent Document 1, it is unclear to what extent it is effective in suppressing allergic symptoms in a dry state. Therefore, even if the composition of Patent Document 1 is applied to bedding, it is unclear whether or not the effect of suppressing the symptom of morning attack can be obtained. Since the composition of Patent Document 1 contains a water-soluble polymer in a relatively high concentration, it is considered that the composition has a high viscosity and is unsuitable for spraying or cannot be sprayed. Therefore, even in this sense, it is not realistic to apply it to bedding and the like.

The present invention has been made in view of this point, and an object of the present invention is to improve the sleeping environment and further improve the quality of sleep.

In order to achieve the above object, in the present invention, a liquid containing a soaring inhibitor and an inorganic salt having a protein converging effect is attached to the bedding.

The first invention is a sleeping environment improving agent consisting of a liquid containing an anti-flying agent and an inorganic salt having a protein converging effect, 15 to 60 minutes before going to bed, with an average particle size (D50 value) of 70 μm or more and 150 μm. It is a sleeping environment improving method characterized by spraying the following particles on the bedding and adhering them to the bedding.

According to this configuration, when the sleeping environment improving agent is sprayed on the bedding using, for example, a sprayer, inorganic salts having a protein converging effect adhere to the allergen. As described above, the main allergens are pollen, mite carcasses, feces and the like, and since these are proteins, the allergen is inactivated by the adhesion of inorganic salts having a protein converging effect to the allergen. Then, the allergen aggregates due to the soaring inhibitor to form large particles. This makes it difficult for allergens to soar. Even if all allergens are not inactivated, the flocculant makes it difficult for the allergens to fly up, thus reducing the amount of allergens that humans inhale. From the above, allergic reactions are suppressed. In particular, by spraying the allergy-suppressing composition on the bedding, it becomes possible to suppress the symptoms of morning attack.

In addition, dust and the like adhering to the bedding also aggregates due to the aggregation effect of the soaring preventive agent, making it difficult to soar.

Further, since the inorganic salts having a protein converging effect have a bactericidal effect of various germs adhering to the bedding, the bedding sterilization, antibacterial and deodorant effects can also be obtained.

According to the first invention, since the sleep environment improving agent contains a soaring preventive agent and an inorganic salt having a protein converging effect, the sleeping environment is improved by spraying the bedding or the like to improve the quality of sleep. Can be further enhanced.

It is a side view of the sleep environment improvement product which concerns on embodiment of this invention. It is a figure explaining the usage procedure of a sleep environment improvement product.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is essentially merely an example and is not intended to limit the present invention, its application or its use.

FIG. 1 is a side view of the sleep environment improving product 1 according to the embodiment of the present invention, and FIG. 2 is a diagram illustrating a usage procedure of the sleeping environment improving product 1. The sleep environment improving product 1 is housed in a container 2 and a container 2 containing a sleeping environment improving agent composed of a liquid containing a soaring preventive agent and an inorganic salt having a protein converging effect, and a sleeping environment improving agent. It is provided with a sprayer 4 for spraying the sleeping environment improving agent on the bedding 100, 101, 102 (shown in FIG. 2).

The container 2 is made of, for example, a resin container. For example, a resin cap 3 is attached to the upper part of the container 2. The container 2 and the cap 3 are removable, and for example, when the sleeping environment improving agent in the container 2 runs out, it can be replaced with a new container 2. The atomizer 4 includes an operation lever 41 and a pressure accumulator portion 42, and is configured to spray the sleep environment improving agent in the container 2 by operating the operation lever 41. The upper part of the operating lever 41 is pivotally supported with respect to the cap 3, and the operating lever 41 swings by operating the lower part of the operating lever 41 with a finger or the like. A spray port 41a for spraying the sleeping environment improving agent is formed on the upper portion of the operating lever 41.

The atomizer 4 is configured as a known accumulator spray. That is, the mechanical energy is accumulated by operating the operation lever 41, and the sleep environment improving agent is pressurized by the mechanical energy to spray the sleeping environment improving agent from the spray port 41a. ing. Such a pressure-accumulation type spray has a feature that stable spraying can be maintained for a certain period of time because the operating force applied to the operating lever 41 is temporarily stored as mechanical energy and then the contents are pressurized. As a result, the bedding and the like can be sprayed evenly, which is particularly suitable as a sprayer for a sleeping environment improving agent.

The pressure accumulator 42 of the atomizer 4 of the present embodiment is configured to store the mechanical energy by elastic deformation by an elastic member (specifically, a metal spring). Since the mechanical energy is stored by the metal spring, there is an advantage that the pressure accumulator 42 can be formed small and efficiently, and the sustainability and stability of the spray are also improved. Reference numeral 43 in FIG. 1 is a conduit for guiding the sleeping environment improving agent contained in the container 2 to the accumulator portion 42. By operating the operating lever 41, mechanical energy is stored in the metal spring in the accumulator 42, and a sleep environment improving agent is introduced into the accumulator 42 via the conduit 43, and the sleeping environment improving agent is transferred by the metal spring. It is pressurized and ejected from the spray port 41a. A nebulizer 4 provided with this type of accumulator 42 is described in, for example, Japanese Patent Publication No. 2014-527911.

The average particle size of the sleeping environment improving agent sprayed from the spray port 41a can be arbitrarily set depending on the shape and size of the spray port 41a, the inner diameter of the downstream end of the conduit 43 connected to the spray port 41a, and the like. In this embodiment, the shape and size of the spray port 41a are set so that the average particle size (D50 value) of the sleeping environment improving agent is 70 μm or more and 150 μm or less. By setting the average particle size of the sleeping environment improving agent to 150 μm or less, the particle size becomes small, the surface is less likely to get wet even if it adheres to bedding, and the user is less likely to feel discomfort. Further, by setting the average particle size of the sleeping environment improving agent to 150 μm or less, the sleeping environment improving agent easily penetrates not only on the surface of the bedding but also between the fibers of the cloth. Since the average particle size of the sleeping environment improving agent is 70 μm or more, the particle size does not become unnecessarily small and does not float in the air for a long time, and most of the sprayed sleeping environment improving agent is dropped by gravity. Can be attached to bedding. The lower limit of the average particle size of the sleep environment improving agent is 80 μm or more, and more preferably 85 μm or more. The upper limit of the average particle size of the sleep environment improving agent is 130 μm or less, and more preferably 100 μm or less.

When measuring the average particle size of the sleep environment improving agent, LDSA-SPR-1500A manufactured by Microtrac Bell Co., Ltd. can be used as the particle size measuring machine. The average particle size is D50 (cumulative 50%) measured by a particle size measuring machine and analyzed by an automatic arithmetic processing unit. Specifically, the sleeping environment improving agent, which is an ejector, emits the laser beam from a position where the distance between the laser beam radiated from the laser light irradiating portion of the particle size measuring machine to the light receiving portion and the injection port 41a is 20 cm. The sleep environment improving agent is sprayed so as to pass in a direction orthogonal to the irradiation direction. It can be obtained by measuring during the injection of the sleep environment improving agent and analyzing the particle size distribution of the sleeping environment improving agent with an automatic calculation processing device. This method has been well known in the past.

It is also possible to store the sleeping environment improving agent together with the propellant in an aerosol container to make an aerosol product. As the propellant in this case, for example, various gases such as liquefied petroleum gas and dimethyl ether can be used. In addition, the sleeping environment improving agent can be used by being stored in a container such as a spray bottle.

The sleep environment improving agent according to the embodiment of the present invention contains a soaring preventive agent (aggregating agent) that aggregates allergens, an inactivating agent that inactivates allergens, an organic medium, and water. The sleep environment improving agent inactivates pollen, mite carcasses, feces, etc. as allergens with an inactivating agent, and at the same time, aggregates multiple allergens with an aggregating agent to form large particles and make it difficult to fly up, thereby causing allergies. It is intended to suppress, deodorize and antibacterial the bedding, and to improve the sleeping environment.

The sleeping environment is a bedroom environment, which is an environment from the sleep preparation stage before sleep to during sleep and immediately after waking up. The sleep environment improving agent can improve the environment from the sleep preparation stage to during sleep and immediately after waking up by using it in the sleep preparation stage before sleep in the bedroom. The specific improvement effect will be described later.

The sleeping environment improving agent is preferably used by spraying it indoors, for example, by adhering it to bedding (including comforter 100, mattress 101, pillow 102, etc.), sofa, curtain, rug, tatami mat, etc. shown in FIG. can do. At this time, the range to which the sleep environment improving agent is attached can be the range surrounded by the alternate long and short dash line indicated by the symbol A. That is, the range includes the upper part of the comforter 100, the upper part of the mattress 101, and the pillow 102.

The above-mentioned anti-flying agent is a polymer having an action of aggregating particles such as allergens and dust to make it difficult to scatter, for example, polyacrylate, and examples of the polyacrylate include sodium polyacrylate. Can be done. The sodium polyacrylate can be either non-crosslinked sodium polyacrylate (for example, Alonbis SX or Alonbis MX manufactured by Toa Synthetic Co., Ltd.) or crosslinked sodium polyacrylate (for example, Leosic 260H manufactured by Toa Synthetic Co., Ltd.). However, these may be mixed and used, but non-crosslinked sodium polyacrylate is preferable in terms of the effect of aggregating allergens.

The content of polyacrylate is set to 0.0001% by weight or more and 0.005% by weight or less. If the content of polyacrylate is less than 0.0001% by weight, the allergen aggregation effect is significantly reduced. Therefore, the lower limit of the content of polyacrylate should be 0.0001% by weight or more. It is preferable, more preferably 0.0005% by weight or more. In addition, the coagulant can also agglomerate dust and the like adhering to bedding and the like.

On the other hand, when the content of the polyacrylate exceeds 0.005% by weight, the self-aggregation of the polyacrylate is likely to proceed and is in a stable state during and after the production until the user uses it. The upper limit of the content of polyacrylate is preferably 0.005% by weight or less, and more preferably 0.003% by weight or less. In addition, if the content of polyacrylate is too high, the viscosity of the sleeping environment improving agent becomes high, which causes another problem that it is not suitable for spraying. Therefore, the content of polyacrylate is preferably within the above range.

The deactivating agent is an inorganic salt having a protein converging effect, for example, an aluminum salt. Examples of the aluminum salt include aluminum chloride and alum. Aluminum chloride and alum are stable when used as sleeping environment improving agents. The protein converging effect is an effect capable of converging (denaturing) the pollen, dead mites, feces and the like until they are inactivated. Aluminum chloride is preferable because it not only has a high protein converging effect, but also has low irritation when it adheres to human skin, and it does not color when it adheres to a cloth material or the like. In addition, such inorganic salts can be expected to have deodorant and antibacterial effects.

The content of the inorganic salt having a protein converging effect can be set to, for example, 0.2% by weight or more and 20% by weight or less. If the lower limit of the content of the inorganic salt having a protein converging effect is less than 0.2% by weight, the deactivating effect is significantly reduced, so 0.2% by weight or more is preferable. The deactivating effect increases as the content of the inorganic salt having a protein converging effect increases, but if it exceeds 20% by weight, the deactivating effect hardly changes even if the content exceeds 20% by weight. The upper limit of the salt content is preferably 20% by weight or less. The content of aluminum chloride is set higher than the content of polyacrylate.

The organic solvent is, for example, alcohol, but the organic solvent is not limited to this, and various organic solvents can be arbitrarily blended depending on the purpose. The purpose of blending the organic solvent may be, for example, to improve the quick-drying property of the sleeping environment improving agent to improve the usability. In this case, the organic solvent is not particularly limited as long as it is easier to evaporate than water. Lower alcohols can be used, and ethanol is particularly preferable from the viewpoint of safety. As ethanol, for example, fermented alcohol (95 degrees 1st grade) or the like can be used, but synthetic alcohol or the like may also be used.

In the sleeping environment improving agent of the present invention, sufficient deodorant and antibacterial effects can be obtained by using inorganic salts. However, if necessary, an antibacterial agent, a deodorant, a fragrance, or the like may be further added.

As the antibacterial agent, for example, phenoxyethanol, paraoxybenzoic acid ester, sodium benzoate, benzoic acid, benzalkonium chloride and the like can be used. The content of the antibacterial agent is set to be higher than the content of polyacrylate and lower than the content of inorganic salts having a protein converging effect. Specifically, the content of the antibacterial agent is preferably 0.3% by weight or more and 0.8% by weight or less.

Deodorants include, for example, Eporion AS-144 (manufactured by Kyoritsu Seiyaku Co., Ltd.), Fresh E (manufactured by Shirai Matsushinyaku Co., Ltd.), Pancil FG-60, FG-70 (manufactured by Release Kagaku Kogyo Co., Ltd.), Super Puriere. A100-R, Super Purière A-20TEB, Super Purière Z-100 (all manufactured by Panasonic Eco Solutions Kaken Co., Ltd.), etc. can be used. The content of the deodorant is set to be higher than the content of the polyacrylate and lower than the content of the inorganic salts having a protein converging effect. Specifically, the content of the antibacterial agent is preferably 0.05% by weight or more and 0.5% by weight or less.

As the fragrance, various natural essential oils, synthetic fragrances and the like can be used. As the water, normal water can be used. The water content is the remnants of flocculants, deactivating agents, alcohols, antibacterial agents, deodorants and fragrances. It is not necessary to contain any one or more of alcohol, antibacterial agent, deodorant and fragrance. Further, other additives may be added as long as the effects of the soaring inhibitor and the deactivating agent are not reduced.

By the way, in the process leading to the present invention, the inventors of the present application have found that polyacrylates are more effective in aggregating allergens than ordinary (non-salt) polyacrylic acids. It is thought that this is because salts are more easily ionized than ordinary polyacrylic acid, and therefore it is easier to capture fine charged particles (allergens, etc.).

Therefore, the inventors of the present application have come up with the idea of blending an inorganic salt as a deactivating agent with polyacrylate as a soaring preventive agent through repeated diligent studies. However, when I actually tried this, I faced the problem that polyacrylates self-aggregate and precipitate very easily. This is probably due to the fact that the polyacrylic acid ions ionized in water combine with the ions of the above-mentioned inorganic salts that are also ionized in water.

Therefore, the inventors of the present application wondered if self-aggregation could be prevented by adjusting the concentrations of polyacrylate and inorganic salts, but for example, lowering the concentration of polyacrylate reduces the allergen aggregation effect. It is expected that lowering the concentration of inorganic salts will reduce the allergen inactivation effect, so it seems impossible to achieve both the allergen suppression effect and the prevention of self-aggregation.

However, as a result of diligent research by the inventors of the present application, it was found that by setting the polyacrylate in the above concentration range, self-aggregation of the polyacrylate does not occur and a sufficient allergen aggregation effect can be obtained. It came to the invention. Although the concentration range of the polyacrylate is extremely low (0.0001% by weight or more and 0.005% by weight or less), it was completely surprising that a sufficient allergen aggregation effect could be obtained even at such a low concentration. ..

Furthermore, the inventors of the present application have also found that by setting the concentration range of the inorganic salts in the above concentration range, a sufficient allergen deactivating effect can be obtained, and self-aggregation of the polyacrylate does not occur. That is, by setting the concentrations of the polyacrylate and the inorganic salts within the above range, it is possible to obtain an allergy-suppressing composition that does not cause precipitation due to self-aggregation and has a high effect. Moreover, since the concentration of polyacrylic acid salt is sufficiently low as described above, the viscosity of the sleeping environment improving agent is also low, so that it is suitable for spraying with a sprayer 4, has good spraying properties, and can be sprayed evenly on bedding and the like. Very good at.

(Manufacturing method of sleep environment improving agent)
Next, a method for producing a sleep environment improving agent will be described. As a method for producing a sleeping environment improving agent, a polyacrylate dispersion generation step of obtaining a polyacrylate dispersion in which polyacrylate is dispersed in water and an antibacterial agent solution in which an antibacterial agent is dissolved in alcohol are obtained. Inorganic salt dissolution step (chloride) in which inorganic salts having a protein converging effect (aluminum chloride in this embodiment) are dissolved in the polyacrylate dispersion produced in the antibacterial agent solution generation step and the polyacrylate dispersion generation step. It is equipped with an aluminum melting step).

In the polyacrylate dispersion liquid generation step, the polyacrylate is dispersed in water by adding the polyacrylate to water and stirring the mixture. At this time, the mixture is stirred in the absence of alcohol. This suppresses self-aggregation of polyacrylates. Further, in the step of producing the polyacrylate dispersion liquid, it is preferable to use a small tank to disperse the polyacrylate in water.

In the antibacterial agent solution generation step, phenoxyethanol is added to the alcohol and stirred, and the phenoxyethanol is dissolved in the alcohol to obtain an antibacterial agent solution. In this antibacterial agent solution generation step, the deodorant and the fragrance may be added to the alcohol and stirred to dissolve the deodorant and the fragrance in the alcohol. As a result, a solution in which phenoxyethanol, a deodorant and a fragrance are dissolved is obtained.

In the inorganic salt dissolution step, aluminum chloride is added to water and stirred, and the aluminum chloride is dissolved in water to obtain an aluminum chloride solution.

The polyacrylate dispersion liquid generation step, the antibacterial agent solution generation step, and the aluminum chloride dissolution step are performed using separate tanks. These three steps may be performed at different timings or may be performed in parallel.

Then, the polyacrylate dispersion produced in the polyacrylate dispersion generation step is transferred to a large tank, water is added to the tank, and the process of stirring is performed a plurality of times in the polyacrylate dispersion. We will increase the proportion of water.

Then, the polyacrylate dispersion is transferred to a larger tank, water is added, and then the aluminum chloride solution produced in the aluminum chloride dissolution step is put into the tank and stirred. Then, after adding water and stirring, alcohol is added and stirred. That is, since alcohol is added to the polyacrylate dispersion liquid in which the polyacrylate is dispersed, self-aggregation of the polyacrylate is suppressed.

After that, a solution in which phenoxyethanol, a deodorant and a fragrance are dissolved in alcohol is added and stirred, and then alcohol is added and stirred. Finally, water is added and stirred to obtain a sleeping environment improving agent.

As described above, after the polyacrylate is dispersed in water, the inorganic salts having a protein converging effect are dissolved, so that the polyacrylate is less likely to self-aggregate during the production, and after the production, it is difficult to self-aggregate. Self-aggregation of polyacrylate is suppressed even before use by the user. As a result, a stable state is maintained for a long period of time.

(How to improve sleep environment)
Next, a method for improving the sleeping environment will be described. The sleep environment improving method includes a step of preparing a sleeping environment improving agent and spraying the prepared sleeping environment improving agent on the bedding, and is also a method of using the sleeping environment improving agent. The sleeping environment improving agent may be stored in the above-mentioned container 2 or may be stored in a container having another structure. It is preferable to spray the bedding with a sleep environment improving agent at the sleep preparation stage before sleep.

When the sleeping environment improving agent is sprayed on the bedding, inorganic salts having a protein converging effect adhere to the allergen. The allergen is inactivated by the adhesion of inorganic salts having a protein converging effect to the allergen. Then, the allergen aggregates due to the aggregation effect of the polyacrylate, and large particles are formed. This makes it difficult for allergens to soar. Even if all allergens are not inactivated, the flocculant makes it difficult for the allergens to fly up, thus reducing the amount of allergens that humans inhale. From the above, allergic reactions are suppressed. In particular, by spraying the allergy-suppressing composition on the bedding, it becomes possible to suppress the symptoms of morning attack.

In addition, dust and the like adhering to the bedding also aggregates due to the aggregation effect of the polyacrylate, making it difficult to fly up. The above-mentioned inorganic salts cannot come into contact with the allergen existing inside the dust and may not be inactivated. However, since the polyacrylate can prevent the allergen from flying up, it inhales the allergen that has not been inactivated. The amount will be small. Further, since the inorganic salts having a protein converging effect have an effect of killing various germs adhering to the bedding, the bedding sterilization, antibacterial and deodorant effects can also be obtained.

Therefore, in the case of hay fever patients and allergic patients, there is a tendency that a runny nose is less likely to occur in the preparatory stage before sleep, and sneezing is suppressed, making it easier to fall asleep. In addition, the influence of runny nose and the like during sleep can be reduced, and the quality of sleep can be improved.

(Action and effect of the embodiment)
Hereinafter, the effects of the sleep environment improving agent will be specifically described based on the test results. First, the antibacterial test results will be described. The antibacterial test method is a method based on JIS1902. The test bacterium is Staphylococcus aureus (S. aureus: NBRC12732). The test agents were 68% by weight of tap water, 0.001% by weight of Aronbis SX, 30% by weight of ethanol, 1.000% by weight of aluminum chloride, 0.5% by weight of Super Purière A100-R, and Neolon. Test agent 1 containing 0.5% by weight of (phenoxyethanol), 69% by weight of tap water, 0.001% by weight of Alonbis SX, 30% by weight of ethanol, and 1.000% by weight of aluminum chloride. Agent 2 was prepared. Both Test Agent 1 and Test Agent 2 had a sterilizing effect of 99.999%. That is, a high antibacterial effect can be obtained by the antibacterial action of aluminum chloride regardless of the presence or absence of an antibacterial agent such as phenoxyethanol.

Next, the deodorant effect will be described. First, to explain the deodorization test method, 1 mL of a liquid malodor source is taken and applied to a filter paper (ADVANTEC, No5A, 90 mm) in a glass petri dish. Immediately after that, 1 mL of the following test agent 3 is applied to the same filter paper. Next, the filter paper and the glass petri dish are transferred into a glass cylinder having an internal volume of 18 L, and the glass cylinder is covered with a glass lid. The malodor concentration in the glass cylinder was measured with a detector tube 30 minutes, 1 hour, 2 hours, and 3 hours after the lid was closed. Two types of malodor sources, an acetaldehyde aqueous solution (0.1 g / 100 mL) and a 25% ammonia aqueous solution (0.15 / 100 mL), were prepared and tested separately.

The test agents were 68% by weight of tap water, 0.001% by weight of Aronbis SX, 30% by weight of ethanol, 1.000% by weight of aluminum chloride, 0.5% by weight of Eporion AS144, and neolon (phenoxyethanol). A test agent 3 having an amount of 0.5% by weight was prepared.

As a result of the test, when the test agent 3 was applied to both of the two types of malodor sources, the malodor concentration after 30 minutes was 0 ppm, and the deodorization rate was 100%. When the test agent 3 was not applied, the malodor concentration after 3 hours was 20 ppm in the case of acetaldehyde and 15 ppm in the case of ammonia.

Next, the effect of suppressing allergic symptoms (including the symptoms of pollinosis) will be described. First, a test method for suppressing allergic symptoms will be described. The subjects of the test were 13 people with allergic symptoms. The period was 2 weeks during the pollen dispersal period, and the timing of the start of the test was the timing of the onset of allergic symptoms in each test subject.

The test agents were 68.5% by weight of tap water, 0.001% by weight of Alonbis SX, 30% by weight of ethanol, 1.000% by weight of aluminum chloride, and 0.5% by weight of Super Purière A100-R. The test agent 4 was prepared. The test agent 4 is actually attached to the bedding normally used by the test subject. The range to which the test agent 4 is attached is the range indicated by reference numeral A in FIG. The test agent 4 was applied to the bedding every night 15 to 60 minutes before going to bed. The amount to be adhered was such that the range of reference numeral A was slightly moistened (the amount of spray was about 5 to 10 ml). Since this test agent contains ethanol to improve quick-drying property, it dries in about 15 minutes with this amount of adhesion, and does not cause discomfort such as dampness at bedtime.

For each test subject, according to the symptoms of "watery", "sneezing", "stuffy nose", "nasal itching", "itching eyes", and "watery eyes", before going to bed and immediately after waking up, respectively. I got a symptom score. The symptom score was set to 1 to 4 grades, and how the symptom score of each person assigned at the early stage of the onset of allergic symptoms changed after 2 weeks by the use of the test agent 4 was obtained.

As a result, the symptom score before bedtime showed an average improvement of 0.3 for "watery", an average improvement of 0.1 for "sneezing", an average improvement of 0.4 for "stuffy nose", and " An average improvement of 0.18 was seen for "nasal itching", an average improvement of 0.7 for "eye itching", and an average improvement of 0.38 for "watery eyes".

In the symptom score immediately after waking up, the average improvement was 0.03 for "watery", 0.18 improvement for "sneezing", 0.1 improvement for "stuffy nose", and "nose". There was an average improvement of 0.1 for "sneezing", an average improvement of 0.6 for "eye itch", and an average improvement of 0.43 for "watery eyes".

As described above, by using the sleeping environment improving agent according to the present invention, allergic symptoms can be suppressed before going to bed and immediately after waking up.

The allergen deactivation effect of inorganic salts requires the presence of water in the surrounding area. For example, in order to act on the allergen inside the dust, it is necessary to have enough water to moisten the inside of the dust. However, on the other hand, in terms of improving the feeling of use, the sleeping environment improving agent is required to dry quickly, and it is unpleasant that the bedding is damp at bedtime, so it is not preferred. Therefore, since it is not possible to spray a large amount of an aqueous solution of inorganic salts on bedding, it is considered unrealistic to obtain a sufficient allergic symptom suppressing effect with only inorganic salts.

In this respect, the sleep environment deactivating agent of the present invention is allergic to allergies from before bedtime to immediately after waking up, even though the amount of spray is such that it dries in about 15 minutes by using an anti-scattering agent in combination with inorganic salts. It has excellent characteristics that cannot be predicted from the prior art, such as being able to suppress symptoms.

The above embodiments are merely exemplary in all respects and should not be construed in a limited way. Further, all modifications and modifications belonging to the equivalent scope of the claims are within the scope of the present invention.

As described above, the sleep environment improving agent and the sleeping environment improving method according to the present invention can be used, for example, by spraying on bedding at the sleep preparation stage before sleep.
