Description

[Technical Field]

[0001] The present invention relates to a biodegradable deodorant. [Background technology]

[0002] In recent years, growing awareness of environmental issues has led to an increasing demand for biodegradable deodorizers. In particular, deodorizing human waste, such as feces and urine, is an important issue during disaster evacuation and outdoor activities. However, conventional deodorizers contain chemical substances, and their use and disposal have raised concerns about their potential impact on the environment.

[0003] Furthermore, the deodorizing effect of these deodorizers is temporary, and the residue left after use can cause new unpleasant odors. To solve these problems, deodorizers are required to be biodegradable. Therefore, there is a need to develop biodegradable deodorizers that are environmentally friendly and have effective deodorizing effects.

[0004] For example, Patent Document 1 proposes a deodorant containing gamma-polyglutamic acid (gamma-PGA) and / or its crosslinked product. Bioplastic materials such as gamma-PGA are produced by culturing Bacillus bacteria or halophilic archaea (Natrialba aegyptiaca), which results in high production costs and leaves room for practical application.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-081040 Summary of the Invention [Problem to be solved by the invention]

[0006] Previous technologies have had problems with the durability of the deodorizing effect, safety, cost, and other aspects, making it difficult to develop an ideal biodegradable deodorizer. For example, in disasters and outdoor activities, deodorizers are required to have a durable effect, be portable, and be easy to handle after use. For example, when applying to animals such as pets, consideration must be given not only to the deodorizing effect and durability, but also to safety in the event of accidental ingestion.

[0007] Therefore, there is a need for the development of a new biodegradable deodorizer that has a low environmental impact, a long-lasting deodorizing effect, can be used in disasters, during outdoor activities, on animals, etc., and is easy to handle after use. The object of the present invention is to provide a biodegradable deodorizer that meets these requirements. [Means for solving the problem]

[0008] In order to solve the above problems, the present inventors have made extensive research efforts and have unexpectedly discovered that by combining plant powder and dried ginger, it is possible to provide a biodegradable deodorizer that has a low environmental impact and an extremely good deodorizing effect, thereby completing the present invention.

[0042] [Application] The deodorizer of the present invention can be used for deodorizing various places and purposes, such as indoor spaces, homes with pets, kitchens, toilets, car interiors, shoe cabinets, and sporting goods.

[0043] In addition to the above uses, the biodegradable deodorant of the present invention is expected to be used in various situations due to its low environmental impact and long-lasting effect. In particular, it is expected to be useful in situations that are different from normal living environments, such as welfare facilities, evacuation life in the event of a disaster, and outdoor activities.

[0044] For example, in welfare facilities, where many people live together, certain odors are likely to occur. The biodegradable deodorizer of the present invention can neutralize odors by directly contacting the source of the odor. Furthermore, because it is biodegradable, it has little impact on the environment, helping to maintain a comfortable living environment for facility users and staff. Furthermore, because the deodorizer's ingredients are naturally derived, it can be used safely even in facilities where people with sensitive skin are present.

[0045] During evacuation in the event of a disaster, maintaining hygienic conditions makes deodorization an important issue. Many people live in a limited space in evacuation shelters, and toilet odors and other household odors tend to become problems. The biodegradable deodorizer of the present invention can effectively deodorize these odors by utilizing its biodegradable properties. It is also possible to adopt a shape and packaging that allows for easy use so that it can be used safely even in emergencies. This reduces the stress of evacuation life and provides a hygienic environment.

[0046] In outdoor activities, there is a growing need for comfort while emphasizing coexistence with nature. Effectively deodorizing the odors of food, body odor, and waste that arise during activities such as camping and hiking will enable a more comfortable outdoor experience. The biodegradable deodorizer of the present invention uses biodegradable ingredients that are environmentally friendly and has minimal impact on the environment after use, making it suitable for use in nature. Furthermore, to support a sustainable outdoor lifestyle, it can be designed for excellent portability, and its shape and packaging can be adopted to make it easy to carry anywhere.

[0047] Furthermore, in the environment of pets and livestock animals, some animals, such as dogs and cats, have a sense of smell that is tens to hundreds of times stronger than that of humans, so using a biodegradable deodorizer with reduced artificial fragrances can reduce stress on pets and livestock animals. Furthermore, even if a pet or livestock animal accidentally ingests a biodegradable deodorizer made with naturally derived ingredients, it is highly safe for the living body and can reduce the impact of accumulation in the body. It can be used in the excretion areas and living areas of pets and livestock animals, and can be used in the form of pellets or processed into sheets, mats, etc.

[0048] [container] The biodegradable deodorant of the present invention can be suspended in an aqueous medium such as water and filled into a spray container for easy spraying. Furthermore, when used without direct spraying, it can also be placed in a breathable cloth bag or mesh container. When using a spray container, the deodorant can be sprayed in a fine mist, effectively diffusing the deodorizing ingredients over a wide area. When using a cloth bag or mesh container, the area of ​​the deodorant directly exposed to air is increased, and more effective deodorization can be expected. Furthermore, the biodegradable deodorant of the present invention can be compressed to an appropriate size, molded into pellets, dried, or otherwise packaged in a container. Examples of containers for pellets include steel cans, fiber drums, and recyclable containers.

[0049] The malodorous components to be deodorized are not limited, but may include, for example, at least one selected from the group consisting of ammonia, indole, skatole, hydrogen sulfide, and n-butyric acid. From the viewpoint of the applicable range of deodorization, it is preferable that a plurality of malodorous components can be deodorized, more preferably two or more of the above malodorous components, even more preferably three or more, particularly preferably four or more, and most preferably five or more.

[0050] Among the above-mentioned malodorous components, ammonia is highly unpleasant due to its irritation to the eyes and throat, and can be a problem in the so-called "toilet odor" and "urine odor." The ability to significantly deodorize ammonia makes it possible to suitably use the product for, for example, urine, used diapers, exudates from bedsores, bedding for pets and livestock, etc.

[0051] Among the above-mentioned malodorous components, indole is one of the components that cause fecal odor and putrid odor, and when it is concentrated in high concentrations, it causes a very unpleasant feeling. By being able to significantly deodorize indole, it can be suitably used for, for example, feces, residual odor after defecation, residual odor in the air after using the toilet, etc.

[0052] Among the above malodorous components, skatole is perceived as a particularly "heavy" and "muddy" malodor among feces odors. By being able to significantly deodorize skatole, the product can be suitably used for, for example, feces, residual odors after defecation, and residual odors in the air after using the toilet.

[0053] Among the above-mentioned malodorous components, hydrogen sulfide is perceived as a malodor even in trace amounts, and at high concentrations can lead to olfactory paralysis and even death. The ability to significantly deodorize hydrogen sulfide makes it suitable for use in, for example, drainage pipes, toilets, areas where sewage treatment is incomplete, areas where fermentation or decay is occurring, etc.

[0054] Among the above-mentioned malodorous components, n-butyric acid has a strong, unpleasant odor that can even cause nausea. The ability to effectively deodorize n-butyric acid makes it suitable for use against, for example, body odor (foot and skin), long-worn clothing, abandoned waste, fermented feed, and decaying residue in cages.

[0055] Although not limited thereto, by using the biodegradable deodorant of the present invention, it is possible to significantly deodorize ammonia, indole, skatole, and n-butyric acid, which are the main causative components of excrement (urine, feces, etc.), and therefore it is possible to effectively deodorize, for example, urine and feces excreted in the toilet, residual odors after diaper changes, and accumulated odors due to poor ventilation around the toilet.Although not limited thereto, the deodorizing effect of the present invention can be made even more effective by using it in contact with an object that emits a malodorous component.

[0056] [Manufacturing method] The method for producing the biodegradable deodorant of the present invention involves mixing plant powder, dried ginger, and optionally dried soybean pulp, polysaccharides, lime, etc. in a predetermined ratio, and optionally further adding calcium carbonate, carboxymethyl cellulose, etc., followed by further pulverization as needed to form a uniform powder or pellets. This mixture is then filled into a container. When using a spray container, the mixture can be diluted with water or an appropriate aqueous solvent and filled into the container.

[0057] [How to use] The biodegradable deodorizer of the present invention can be used by directly spraying it onto the target space or object as needed. When using a spray bottle, spray an appropriate amount as a mist toward the target space or object. When used in a cloth bag or mesh container, it can be placed directly in the desired location to achieve a sustained deodorizing effect. When used in the treatment of excrement, the biodegradable deodorizer of the present invention can be appropriately solidified (without becoming too hard), making the treated material easier to handle and promoting natural decomposition when buried in soil. Furthermore, because the biodegradable deodorizer of the present invention is made from environmentally friendly materials, it can reduce the generation of harmful chemicals when incinerated. This allows for hygienic and effective treatment and disposal of excrement while reducing environmental impact.

[0058] In the case of humans, the average amount of urine per urination is about 200 to 400 mL, so the amount of the biodegradable deodorant of the present invention used per urination can be, for example, 20 to 100 mL, preferably 40 to 80 mL, and more preferably 50 to 70 mL. In the case of pets and livestock animals, the amount used can be adjusted appropriately depending on the amount of urine, and in the case of dogs, assuming urine volumes from small to large dogs, the amount can be, for example, 10 to 60 mL, preferably 15 to 50 mL. In the case of cats, the average amount of urine per urination is, for example, about 20 to 50 mL, so the amount of the biodegradable deodorant of the present invention used per urination can be, for example, 2 to 15 mL, preferably 5 to 10 mL. [Example]

[0059] The present invention will be described below with reference to examples, but the scope of the present invention is not limited thereto. Unless otherwise specified, numerical values ​​such as "%" and "parts" represent numerical values ​​based on mass.

[0060] [Preparation of biodegradable deodorant] Hinoki powder (manufactured by SS Corporation): 95.6% (average particle size 5 mm or less), dried ginger powder (manufactured by Sakata Nobuo Shoten Co., Ltd., ginger residue generated during processing): 4% (average particle size 5 mm or less), and binder (commercially available cornstarch): 0.4% were appropriately weighed and mixed in a mixer until uniform. The mixed powder was processed into pellets (approximately cylindrical, diameter: 3-10 mm, height: 5-30 mm) in a pelletizer to produce a biodegradable deodorant. This biodegradable deodorant is made primarily from hinoki powder and dried ginger, which are naturally degradable. It has been confirmed that the polysaccharide cornstarch acts as a biodegradable binder and is decomposed by microorganisms in the natural environment. The plant powder and other ingredients can be appropriately replaced with biodegradable ingredients as long as the effects of the present invention are achieved. Furthermore, as described above, by blending appropriate amounts of plant powder, dried ginger, and, if necessary, polysaccharides, when used on excreted urine, feces, or toilet waste, for example, the waste does not harden even when it absorbs moisture and remains well-formed, making disposal easy and preventing clogging when drained. Assuming a human urine volume of 300 mL, the appropriate amount of biodegradable deodorant to be used is approximately 60 mL. Assuming a small dog urine volume of 75 mL, the appropriate amount of biodegradable deodorant to be used is approximately 15 mL. Assuming a medium dog urine volume of 150 mL, the appropriate amount of biodegradable deodorant to be used is approximately 30 mL. Assuming a large dog urine volume of 250 mL, the appropriate amount of biodegradable deodorant to be used is approximately 50 mL. Assuming a cat urine volume of 40 mL, the appropriate amount of biodegradable deodorant to be used is approximately 8 mL.

[0061] [Test Example 1. Deodorization Test (1)] Sample preparation and test conditions: Sample amount: 1g of biodegradable deodorant Test container: 1L Tedlar bag Test duration: 30 minutes, 6 hours, 24 hours Equipment used: Gas detector tube and gas chromatography Measurement method: Direct method

[0062] Initial concentration of malodorous components: Ammonia: 150 ppm Hydrogen sulfide: 20 ppm Indole: 30 ppm Skatole: 30 ppm n-Butyric acid: 50 ppm

[0063] Test Method: One gram of biodegradable deodorant was placed in a Tedlar bag, and the above-mentioned malodorous components were sealed in the bag at the specified initial concentration. The bag was left sealed for the specified test time (30 minutes, 6 hours, 24 hours), after which the gas inside the bag was sampled and the remaining concentration of the malodorous components was measured using a gas detector tube and gas chromatography. From this, the deodorizing rate (%) of the deodorant at each time point was calculated. The results are shown in Table 1.

[0064] [Table 1]

[0065] [Test Example 2. Deodorization Test (2)] Sample preparation and test conditions: Sample amount: 1g of biodegradable deodorant Test container: 1L Tedlar bag Test duration: 30 minutes, 6 hours, 24 hours Measurement method: Olfactory measurement method (6-level odor intensity display method) Odor-causing components: ammonia, indole, skatole, hydrogen sulfide, n-butyric acid

[0066] 6-level odor intensity indication method The odor intensity and odor evaluation criteria are as follows: Odor intensity 0: Odorless Odor intensity 1: barely detectable odor (detection threshold) Odor intensity 2: A weak odor that can be identified (recognition threshold) Odor intensity 3: Easily detectable odor Odor intensity 4: Strong odor Odor intensity 5: Strong odor

[0067] Test Method: One gram of biodegradable deodorant was placed in a Tedlar bag, and the above-mentioned malodorous components were sealed inside the bag. The bag was left sealed for the specified test time (30 minutes, 6 hours, 24 hours), after which the malodorous odor inside the container was judged by six routinely trained panelists using a six-level odor intensity rating system. The maximum and minimum values ​​were excluded from the scores, and the average was calculated and shown as the test results. The test results for ammonia, indole, skatole, hydrogen sulfide, and n-butyric acid are shown in Tables 2 to 6, respectively.

[0073] The results of the deodorizing tests confirmed the effectiveness of the deodorizing effect of the biodegradable deodorizer of the present invention against each malodorous component. This data demonstrates that the biodegradable deodorizer of the present invention is environmentally friendly and has effective deodorizing capabilities. Although not limited to this, in the biodegradable deodorizer of the present invention, the average particle size of the plant powder and dried ginger powder is adjusted to 5 mm or less, and the content of the plant powder per part by mass of dried ginger is adjusted to a certain range (1 to 30 parts by mass). Although not limited to this, it is presumed that by molding these into pellets, the plant powder and dried ginger powder are uniformly dispersed within the pellets, and the fibrous structure forms appropriate voids, enabling a good balance between a stable and sustained deodorizing effect and a biodegradable effect after use as a deodorizer.

[0074] [Preparation Example 1 of Biodegradable Deodorant] The following ingredients were weighed and mixed uniformly in a mixer: 70% cypress powder (manufactured by SS Corporation) (average particle size 5mm or less), 4% dried ginger powder (manufactured by Sakata Nobuo Shoten Co., Ltd.) (average particle size 5mm or less), 15% binder (commercially available guar gum), 10% dried soy pulp (commercially available), and 1% lime (commercially available). The mixed powder was then put into a pelletizer and formed into pellets to produce a biodegradable deodorant.

[0075] [Biodegradable deodorant preparation example 2] The following ingredients were weighed and mixed in a mixer until uniform: 60% cedar powder (manufactured by SS Corporation) (average particle size 5mm or less), 3% dried ginger powder (manufactured by Sakata Nobuo Shoten Co., Ltd.) (average particle size 5mm or less), 20% binder (commercially available tapioca-derived starch), 15% dried soy pulp (commercially available), and 2% lime (commercially available). The mixed powder was then put into a pelletizer and formed into pellets (approximately cylindrical, diameter: 3-10mm, height: 5-30mm) to produce a biodegradable deodorant.

[0076] [Biodegradable deodorant preparation example 3] The following ingredients were weighed and mixed in a mixer until uniform: 67% cypress powder (manufactured by SS Corporation) (average particle size 5mm or less), 5% dried ginger powder (manufactured by Sakata Nobuo Shoten Co., Ltd.) (average particle size 5mm or less), 2% binder (commercially available guar gum), 20% dried soybean pulp (commercially available), 5% lime (commercially available), and 1% carboxymethyl cellulose. The mixed powder was then put into a pelletizer and formed into pellets (approximately cylindrical, diameter: 3-10mm, height: 5-30mm) to produce a biodegradable deodorant.

[0077] [Biodegradable deodorant preparation example 4] The following ingredients were weighed and mixed in a mixer until uniform: 70% Hinoki powder (manufactured by SS Corporation) (average particle size 5mm or less), 4% dried ginger powder (manufactured by Sakata Nobuo Shoten Co., Ltd.) (average particle size 5mm or less), 3% binder (commercially available guar gum), 18% dried soybean pulp (commercially available), 4% lime (commercially available), and 1% carboxymethyl cellulose. The mixed powder was then put into a pelletizer and formed into pellets (approximately cylindrical, diameter: 3-10mm, height: 5-30mm) to produce a biodegradable deodorant.

[0078] In these biodegradable deodorants, the average particle size of the plant powder and dried ginger powder is adjusted to 5 mm or less, and the content of plant powder per part by mass of dried ginger is adjusted to a specific range (1 to 30 parts by mass). Therefore, by forming the deodorant into pellets, the plant powder and dried ginger powder are uniformly dispersed within the pellets, and the fibrous structure forms appropriate voids, enabling a well-balanced deodorizing effect that is stable and sustained, as well as biodegradable after use as a deodorant. In an acute oral toxicity test using rats, the biodegradable deodorant of the present invention was administered orally at a single dose of 2,000 mg / kg to five male Wistar rats and observed for 14 days from the date of administration. No deaths were observed, and no abnormalities in weight progression or general condition were observed in any of the test animals (data not shown). Therefore, it is possible to provide a biodegradable deodorant that takes safety into consideration, even when used on animals such as pets, where there is a risk of accidental ingestion of a portion of the deodorant.

[0079] [Test Example 3. Biodegradation Test] A flowerbed was created using commercially available gardening soil, and an appropriate amount of the biodegradable deodorant prepared in Preparation Example 4 was placed therein, and the difference in biodegradability was evaluated between (1) when it was mixed with the soil and (2) when it was simply placed on top of the soil. The results from the first day of the test to the second day after the start of the test are shown in Figure 1, the results from the seventh to 12th days after the start of the test are shown in Figure 2, and the results from the 15th to 30th days after the start of the test are shown in Figure 3.

[0080] As shown in Figures 1 to 3, (1) when the biodegradable deodorizer was mixed with soil, it began to soften and lose its shape on the first day after the start of the test, completely disintegrated on the seventh day, the number of lumps decreased on the 11th day, the lumps became difficult to see on the 12th day, and from the 15th day onwards it became almost impossible to see with the naked eye.

[0081] In addition, (2) when the biodegradable deodorizer was simply placed on the soil, it began to soften and lose its shape on the second day after the start of the test, continued to disintegrate on the seventh day, had decomposed into flakes on the eleventh day, the number of flakes decreased on the 15th day, and it became difficult to distinguish it from the soil from the 29th day onwards.

[0082] As described in Test Examples 1 and 2, the biodegradable deodorant of the present invention, which contains plant powder and dried ginger powder, has been shown to have a significant deodorizing effect against each malodorous component. Because dried ginger powder contains antibacterial components, adding a large amount of dried ginger powder may actually inhibit microbial activity. While not intended to be limiting, it is believed that the biodegradable deodorant of the present invention maintains a gentle antibacterial effect and achieves a balance that does not interfere with microbial activity because the average particle size of the plant powder and dried ginger powder is adjusted to 5 mm or less and the content of plant powder per part by mass of dried ginger is adjusted to a certain range (1 to 30 parts by mass). By molding these into pellets, the plant powder and dried ginger powder are uniformly dispersed within the pellets (without localized high concentrations), and the fibrous structure forms appropriate voids, increasing the surface area and expanding the contact area with moisture and microorganisms in the soil, thereby accelerating physical disintegration. Furthermore, although not limited thereto, it is speculated that the biodegradable deodorizer of the present invention further contains dried soybean pulp, which is rich in protein and carbohydrates (soluble components), and thus serves as a highly nutrient source that is immediately available to soil microorganisms, and that the microorganisms in the soil intensively decompose the soybean pulp components, and then expand their decomposition activity to other components (cypress powder, ginger powder), thereby catalyzing the overall decomposition process.
