[0001] The present invention relates to a deodorizing and disinfecting cleaner and sheet-like article for removing dirt from a surface to be cleaned, disinfecting and removing bacteria and viruses at the same time, and deodorizing the surface to be cleaned and its surroundings, and in particular for cleaning, deodorizing and disinfecting floors, tatami mats, wallpaper, floors, walls, equipment, electrical appliances, etc. in a residence, a living room, a toilet, or a kitchen, or a room where a pet is kept. [Background technology]

[0002] Dirt, bacteria, and unpleasant odors occur in various places in a home. Viral contamination can also occur in the home through people and animals.

[0003] A variety of cleaning agents and deodorants are available to remove dirt, bacteria, unpleasant odors, viruses, and the like.

[0004] In recent years, especially in Japan, the number of people living in a household has decreased, and single-person households are becoming the norm. In response to this, an increasing number of households are keeping pets in search of comfort. The number of indoor dogs is also on the rise, and reflecting this situation, there is a demand for products that can easily remove dirt, germs, viruses, and unpleasant odors from within the home.

[0005] Against this background, numerous proposals have been made.

[0006] For example, JP 2000-325453 A describes a deodorant that is made by adding a plant extract, a specific type of organic acid (salt) such as citric acid, glyoxylic acid, and a specific type of water-soluble solvent such as propylene glycol. The specification describes specific examples of plant extracts, but does not mention green tea extract. Also, there is no mention of cyclodextrin.

[0007] Japanese Patent Application Laid-Open No. 4-156851 discloses a deodorant made of cyclodextrin and organic acids including citric acid, but there is no mention of green tea extract in the specification.

[0008] JP 2002-45893 A discloses a method for deodorizing wastewater or sludge containing hydrogen sulfide or methyl mercaptans by using peroxides and organic acids having a carboxylic acid group, but does not disclose the use of cyclodextrin or green tea extract.

[0009] Patent No. 3223203 discloses a pet deodorant containing organic acids including citric acid and wheat bran extract. In this document, organic acids are used to obtain an acid extract of wheat bran. Also, α-, β-, and γ-type cyclodextrins are used to remove the wheat odor of the wheat bran extract. On the other hand, there is no mention of green tea extract.

[0010] Patent No. 4611498 discloses a deodorant composition containing a plant extract, citric acid and its salt, and ethanolamine, and having a pH of 4 to 5.5. In the detailed description of the invention, specific plant extracts are described, but there is no mention of green tea extract. Furthermore, there is no mention of cyclodextrin.

[0016] [Patent Document 1] JP 2000-325453 A [Patent Document 2] Japanese Patent Application Publication No. 4-156851 [Patent Document 3] JP 2002-45893 A [Patent Document 4] Patent No. 3223203 [Patent Document 5] Patent No. 4611498 [Patent Document 6] Patent No. 4647443 [Patent Document 7] Patent No. 4754267 [Patent Document 8] Patent No. 5031355 [Patent Document 9] JP 2019-115646 A [Patent Document 10] JP 2019-156999 A Summary of the Invention [Problem to be solved by the invention]

[0017] Conventionally, deodorants that disinfect and deodorize by spraying on a target surface cannot remove dirt, so even if they can deodorize and disinfect, odors and bacteria may still occur over time. There was also concern that pets and small children could be harmed by coming into contact with the dirt.

[0018] For this reason, it is desirable to provide a method for easily removing dirt from a target surface, leaving a clean finish, and to suppress the generation of odors and the proliferation of bacteria caused by the small amounts of dirt that remain, almost invisible to the naked eye, thereby maintaining a comfortable and safe indoor space even after cleaning.

[0019] The present invention is intended to solve the above problems.

[0020] That is, the object of the present invention is to provide a deodorizing and disinfecting cleaning agent and sheet-like article which can remove most of the dirt on the cleaning surface and at the same time deodorize malodorous substances present in the very small amount of remaining dirt by spraying the deodorizing cleaning agent on the target surface and wiping it with a cloth or the like, or by wiping the target surface with a sheet-like article on which the deodorizing cleaning agent is held in a wet state, which can disinfect the bacteria that grow using the dirt as nutrients to keep the cleaning surface clean, while at the same time suppressing the generation of new malodors due to the bacteria metabolizing the dirt, and furthermore can remove viruses that can be contaminated by humans or animals.

[0021] Furthermore, the present invention aims to provide a deodorizing and disinfecting cleaner and sheet-like article that can clean dirt from houses where pets are kept indoors, remove germs and viruses, and eliminate unpleasant odors, and that, after cleaning, leaves no stickiness due to residual cleaner and leaves a surface that is safe for small children and pets to touch with their hands and feet on the floor without the need for a second wipe. [Means for solving the problem]

[0022] The present invention can be expressed, for example, as follows.

[0023] A deodorizing and disinfecting cleaning agent having a pH of 3.0 to 5.0, containing the following components a), b), c) and d). a) A weakly acidic citrate buffer solution having a concentration of 0.05 to 0.2M (mol / L) and consisting of citric acid and sodium citrate and / or potassium citrate, 70 to 99% by weight. b) 0.02 to 2.0% by weight of green tea extract c) 0.1 to 2.0% by weight of an amphoteric surfactant d) 0.01 to 1.0% by weight of a cationic surfactant

[0024] A sheet-like article comprising the above deodorizing, disinfecting and cleaning agent held in a wet state on a sheet-like substrate. Effect of the Invention

[0025] According to the present invention, dirt can be removed with a single wipe without the need for a double wipe, providing a clean and safe target surface with an excellent finish, while at the same time suppressing the generation of bad odors and the growth of bacteria caused by very small amounts of dirt that remain at an almost invisible level, thereby maintaining a comfortable and safe interior even after cleaning, and furthermore, it is possible to remove viruses that can be contaminated by humans or animals. [Brief description of the drawings]

[0026] [Figure 1] FIG. 1 is a graph showing the correlation between the deodorizing rates when contacting a deodorizing base liquid and when wiping with a deodorizing base sheet. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] (1) The deodorizing and disinfecting cleaning agent of the present invention having a pH of 3.0 to 5.0 (the deodorizing and disinfecting cleaning agent in the sheet-like article of the present invention) can be an aqueous liquid containing the following components a), b), c) and d).

[0028] a) Ingredients

[0029] A weakly acidic citrate buffer solution having a concentration of 0.05 to 0.2 M (mol / L) is composed of citric acid and sodium citrate and / or potassium citrate (i.e., either or both of sodium citrate and potassium citrate).

[0030] This weakly acidic citrate buffer solution is An aqueous solution of citric acid having a concentration of 0.05 to 0.2 M (mol / L); Aqueous sodium citrate solution and / or aqueous potassium citrate solution with a concentration of 0.05 to 0.2M (mol / L) (i.e., either or both of an aqueous sodium citrate solution and an aqueous potassium citrate solution) For example, to prepare a citrate buffer solution of pH 4.1, 100 g of 0.1 M citric acid solution is mixed with about 69.5 g of 0.1 M trisodium citrate solution.

[0031] The deodorizing and disinfecting cleaner of the present invention contains 70 to 99% by weight of this weakly acidic citrate buffer solution.

[0032] The pH of this citrate buffer can be adjusted by the mixing ratio, etc., but from the standpoint of deodorizing performance, it is preferably 3.0 to 5.0, more preferably 3.5 to 4.7, and particularly preferably 4.0 to 4.5.

[0033] By using a weakly acidic buffer solution, it is possible to exhibit excellent deodorizing performance, particularly against ammonia and trimethylamine, which are basic odors.

[0034] The molar concentration of the citrate buffer is preferably 0.075M to 0.15M from the viewpoint of achieving both deodorizing performance and a good finish on hard surfaces.

[0035] b) Ingredients

[0036] It is a green tea extract.

[0037] Green tea extract is generally a very safe base with excellent deodorizing effects. Therefore, even if it is used as a deodorizing and disinfecting cleaner or cleaning sheet, it is safe even if a small amount remains on the target surface. In terms of deodorizing performance, it has an excellent deodorizing effect against ammonia, trimethylamine, and fatty acid odors, so it has the effect of complementing the deodorizing performance of the citrate buffer solution mentioned above.

[0038] A specific example of a green tea extract that can be suitably used is green tea dry distillation extract (product name: Fresh Shiraimatsu [registered trademark]) manufactured by Shiraimatsu Pharmaceutical Co., Ltd.

[0039] The amount of green tea extract blended in the deodorizing and disinfecting cleaner of the present invention is 0.02 to 2.0% by weight as the pure content of green tea extract such as dry distilled green tea extract. If it is less than 0.02%, the deodorizing effect is insufficient, and if it exceeds 2.0% by weight, the finish of the target surface is likely to be impaired.

[0040] c) Ingredients

[0041] It is an amphoteric surfactant.

[0042] Among the amphoteric surfactants, alkylamine oxides, alkyldimethylaminoacetic acid betaines, alkylamidopropyldimethylaminoacetic acid betaines, and alkylhydroxysulfobetaines are preferred.

[0043] Alkylamine oxide reacts with acidic malodors to suppress the volatilization of the malodor components. As the alkylamine oxide, amine oxides having an alkyl group having 8 to 14 carbon atoms are preferred.

[0044] Amphoteric surfactants other than alkylamine oxides react with both acidic and basic malodorous components, and have the effect of suppressing the volatilization of both malodorous components. In terms of deodorizing performance, they have a well-balanced effect on ammonia, trimethylamine, methyl mercaptan, and fatty acids, but are particularly effective on fatty acid odors. Therefore, they have the effect of complementing the deodorizing performance of the above-mentioned citrate buffer solution. The alkyl group of the betaine or amino acid amphoteric surfactant is preferably a single chain type with 10 to 14 carbon atoms. Furthermore, it is preferable to use alkyl dimethyl amino acetic acid betaine and / or alkyl amidopropyl dimethyl amino acetic acid betaine with an alkyl chain length of 10 to 14 carbon atoms as the amphoteric surfactant of component c). The amphoteric surfactants including the alkylamine oxide, betaine, and amino acid types shown here have excellent compatibility with the cationic surfactant, which is an essential component of the deodorizing and disinfecting cleaner of the present invention, and are bases with excellent blending suitability.

[0045] The amphoteric surfactant, component c), removes organic dirt that is the source of malodorous components from the target surface and, at a specific range of concentrations, can give the target surface a clean, non-sticky finish. Furthermore, it has extremely low damage (penetration and causing cracks or breaks in the resin) to ABS (acrylonitrile / butadiene / styrene copolymer) resin, which is used in plastics for housing equipment and home appliances, making it possible to use it for cleaning all kinds of items indoors.

[0046] The amount of amphoteric surfactant blended in the deodorizing and disinfecting cleaner is 0.1 to 2.0% by weight. If it is less than 0.1% by weight, the cleaning power and deodorizing effect are insufficient, and if it exceeds 2.0% by weight, the finish of the target surface is likely to be impaired.

[0047] The alkylamine oxide is known to weaken the infectivity of influenza viruses, coronaviruses, etc. In order to exert this effect, it is preferable that the alkylamine oxide is blended in an amount of 0.10% by weight or more in the deodorizing and disinfecting cleaner.

[0048] The amphoteric surfactants may be used alone or in combination of two or more.

[0049] d) Ingredients

[0050] It is a cationic surfactant.

[0051] Cationic surfactants have a bactericidal effect and can suppress the generation of bad odors caused by bacterial metabolism. In addition, cationic surfactants have the characteristic of having high deodorizing performance for fatty acid odors, so they have the effect of complementing the deodorizing performance of the citrate buffer solution mentioned above.

[0052] The amount of cationic surfactant blended in the deodorizing and disinfecting cleaner is 0.01 to 1.0% by weight. If the amount is less than 0.01% by weight, a sufficient bactericidal effect cannot be obtained, whereas if the amount is 1.0% by weight, a sufficient bactericidal effect can be obtained.

[0053] Furthermore, cationic surfactants have been shown to weaken the infectiousness of viruses such as influenza and coronavirus, and in order to exert this effect, they are preferably incorporated into the deodorizing and disinfecting cleaner in an amount of 0.05 to 1.0% by weight.

[0054] As the cationic surfactant, alkylamine salt type or alkenylamine salt type, quaternary ammonium salt type, pyridine ring salt-containing type are preferably used. The cationic surfactant may be used alone or in combination of two or more.

[0055] As the alkylamine salt type and the alkenylamine salt type, monoalkyl (or alkenyl)amine, dialkyl (or dialkenyl)amine, and trialkyl (or trialkenyl)amine are preferred. The number of carbon atoms in the alkyl group in the alkylamine salt type (or the alkenyl group in the alkenylamine salt type) is preferably 6 to 20. More preferably, it is 10 to 18. The alkyl group (or alkenyl group) can be linear or branched, but is preferably linear. A preferred specific example is LONZA's LONZABAC12 [N-(3-aminopropyl)-N-dodecylpropane-1,3-diamine] ("LONZABAC" is a trademark).

[0056] The quaternary ammonium salt type is preferably a tetraalkyl (or tetraalkenyl) ammonium salt or a benzyl trialkyl (or trialkenyl) ammonium salt. The number of carbon atoms in the alkyl or alkenyl group in the quaternary ammonium salt type is preferably 6 to 20. More preferably, it is 10 to 18. The alkyl (or alkenyl) group can be linear or branched, but is preferably linear. Preferable specific examples include dodecyltrimethyl quaternary ammonium chloride, tetradecyltrimethyl quaternary ammonium chloride, hexadecyltrimethyl quaternary ammonium chloride, benzalkonium chloride having an alkyl group with 8 to 17 carbon atoms, benzethonium chloride, didecyldimethylammonium chloride, and N,N-didecyl-N-methylpoly(oxyethyl)ammonium propionate.

[0057] The pyridine ring salt-containing type is preferably an alkyl (or alkenyl) pyridinium salt, and the number of carbon atoms in the alkyl (or alkenyl) group is preferably 6 to 20. More preferably, the number of carbon atoms is 10 to 18. A preferred example is cetylpyridinium chloride.

[0058] (2) In order to further enhance the deodorizing performance, the deodorizing and disinfecting cleaning agent of the present invention preferably contains, in addition to the above-mentioned components a), b), c) and d), cyclodextrin and / or a derivative thereof as component e).

[0059] Cyclodextrin is approved as a food additive, and when it is used in a deodorizing, disinfecting, or cleaning agent (including when the deodorizing, disinfecting, or cleaning agent is impregnated into a sheet-like product), it has excellent safety properties even if a small amount remains on the target surface.

[0060] Specific examples of cyclodextrin or its derivatives include α-cyclodextrin, β-cyclodextrin, γ-cyclodextrin, hydroxypropylated β-cyclodextrin, methylated β-cyclodextrin, and monochlorotriazinized β-cyclodextrin. Among these, α-cyclodextrin, β-cyclodextrin, hydroxypropylated β-cyclodextrin, methylated β-cyclodextrin, and monochlorotriazinized β-cyclodextrin are preferred. Hydroxypropylated β-cyclodextrin and methylated β-cyclodextrin are more preferred.

[0061] The cyclodextrin or its derivatives can be used alone or in combination of two or more.

[0062] The amount of cyclodextrin and / or its derivatives in the deodorizing and disinfecting cleaner is preferably 0.1 to 2.0% by weight. If it is less than 0.1% by weight, it is difficult to obtain a sufficient deodorizing effect, and if it exceeds 2.0% by weight, the finish of the target surface is likely to be impaired.

[0063] Cyclodextrin or its derivatives exhibit better deodorizing effect on acidic malodors than on basic malodors compared to water, and have high deodorizing performance on methyl mercaptan and fatty acids, and therefore have the effect of complementing the deodorizing performance of the above-mentioned citrate buffer solution.

[0064] (3) The deodorizing and disinfecting cleaner of the present invention preferably contains a water-soluble solvent from the viewpoint of improving the cleaning properties for urine stains, feces, sebum, oils and fats, soap scum and the like, and from the viewpoint of improving the finish.

[0065] Preferred examples of the water-soluble solvent include ethanol, isopropyl alcohol, propylene glycol, isoprene glycol, butanediol, propylene glycol monomethyl ether, hexylene glycol, isopentyldiol, dipropylene glycol, and ethylene glycol monobutyl ether.

[0066] Among these, from the viewpoints of finish and sanitation, ethanol and isopropyl alcohol are more preferred, from the viewpoints of better cleaning power and finish, propylene glycol monomethyl ether is more preferred, and from the viewpoints of odor, finish, non-stickiness even if remaining on the target surface, and low damage to the target plastic surface, propylene glycol, butanediol, hexylene glycol, and isopentyldiol are more preferred. The water-soluble solvent can be used alone or in combination of two or more kinds, taking into account the balance of functional properties as shown here.

[0067] The water-soluble solvent is preferably contained in the deodorizing and disinfecting cleaner in an amount of 2 to 29% by weight. If it is less than 2%, the cleaning power is not fully exerted, and if it exceeds 29% by weight, problems such as odor, stickiness, and degreasing of hands and fingers are likely to occur. The content can be within the range of the remainder excluding the components a), b), c), and d), and the particularly preferred content is 3 to 10% by weight.

[0068] (4) The deodorizing, disinfecting, and cleaning agent of the present invention may further contain, for example, inorganic salts, metal chelating agents, antifouling agents, preservatives, fragrances, colorants, pigments, thickeners, and water.

[0069] An example of an inorganic salt is zinc sulfate, which is a base that has excellent bactericidal and deodorizing effects.

[0070] For use in places that can be rinsed with water, such as kitchen sinks and washstands, a deodorizing and disinfecting cleaner containing an antifouling agent or a sheet-like product in which the deodorizing and disinfecting cleaner is held in a wet state can be provided. Examples of antifouling agents that can be used include ternary amphoteric polymers composed of 15 to 40% (molar ratio) of a quaternary ammonium salt monomer such as diallyldimethylammonium salt or methacrylamidepropyltrimethylammonium salt, 30 to 60% (molar ratio) of an acrylamide monomer, and 10 to 45% (molar ratio) of an anionic monomer such as acrylic acid or its salt, or methacrylic acid or its salt. Preferred specific examples include Mercoat (trademark) 3940, 3330, 3331, 3330PR, 3331PR, 2001, and 2003PR manufactured by Lubrizol Japan, Ltd.

[0071] As the preservative, for example, 3-iodo-2-propynyl butylcarbamate can be mentioned as a base that has a particularly high antifungal effect and is highly safe even if it remains on the cleaning surface. Preferred examples include OMACIDE IPBC 100 ("OMACIDE" is a registered trademark) and Glycacil series ("Glycacil" is a registered trademark) from LONZA.

[0072] (5) The form (method of use) of the deodorizing and disinfecting cleaning agent of the present invention when used is, for example, A method of applying the deodorizing and disinfecting cleaning agent directly to the target surface using a trigger or aerosol sprayer, etc. A method of applying the deodorizing and disinfecting cleaning agent in a liquid state by discharging the agent from a container onto the target surface, A method in which a sheet-like substrate made of a fiber product such as a nonwoven fabric or woven fabric, or paper, or other article (e.g., an article made of a porous material, a non-sheet-like article made of a cloth-like material, a brush-like article, etc.) is impregnated with a deodorizing and disinfecting cleaner to keep it in a wet or other state, and the deodorizing and disinfecting cleaner is applied to a target surface while wiping or otherwise contacting the target surface with the sheet-like substrate (sheet-like article) or other article. etc. can be mentioned.

[0073] (6) In the embodiment of the sheet-like article in which the deodorizing and disinfecting cleaner of the present invention is held in a wet state on a sheet-like substrate, the sheet-like substrate is preferably made of a fiber product such as a nonwoven fabric or a woven fabric containing 30% or more of cellulose fiber in the sheet-like substrate, or paper, from the viewpoints of the holding ability of the deodorizing and disinfecting cleaner in a wet state and the sustained release ability of the deodorizing and disinfecting cleaner on the target surface. Also, from the viewpoints of cleaning ability, deodorizing ability, disinfecting ability, finishing ability, and cleaning area (for a floor, 6 tatami mats to 12 tatami mats), the deodorizing and disinfecting cleaner is preferably held in a wet state on the sheet-like substrate in a ratio of 2 to 4 times the weight of the sheet-like substrate.

[0074] (6-1) Furthermore, from the viewpoint of trapping hair, pet hair, and fibrous dust, the sheet-like substrate is preferably a spunlace nonwoven fabric containing 30 to 100% by weight of cellulosic fibers. Even when a spunlace nonwoven fabric is used as the sheet-like substrate, the amount of the deodorizing and disinfecting detergent retained in a wet state is preferably 2 to 4 times the weight of the sheet substrate.

[0075] (6-2) As for the characteristics of spunlace nonwoven fabrics, from the viewpoint of entangling human hair, pet hair, and fibrous dust, it is particularly preferable that the fibers constituting the nonwoven fabric are loosely entangled with water. However, nonwoven fabrics loosely entangled with water tend to have problems such as stretching when force is applied during cleaning, causing the shape to become distorted and slack, or the fibers constituting the nonwoven fabric becoming caught and pulled out when wiping an uneven surface.

[0076] In this regard, for example, Japanese Patent No. 3664981 discloses an integrated floor cleaning sheet in which a nonwoven fabric-like fiber aggregate formed by entangling the fibers of a fiber web is disposed on one or both sides of a high-strength sheet material.

[0077] By forming the sheet-like substrate in the sheet-like article of the present invention in such a form (for example, a spunlace nonwoven fabric, in which each fiber constituting the nonwoven fabric is loosely entangled with water, on one or both sides of a sheet material that is stronger than the spunlace nonwoven fabric to form a three- or two-layer laminate, and then integrating these together by, for example, entangling the fibers or heat embossing), it is possible to achieve both the ability to trap hair, pet hair, and fibrous dust, the shape stability of the sheet-like substrate, and prevention of fiber loss.

[0078] The sheet-like article of the present invention using the sheet-like substrate having such a configuration can further improve the cleaning performance.

[0079] Examples of high-strength sheet materials include nonwoven fabrics, woven fabrics, resin nets, and resin films. These sheet materials can be made high-strength in order to maintain the strength of the laminated sheet-like article. Test Examples

[0080] (1) Test Examples 1 to 3

[0081] In order to understand the deodorizing performance of various deodorizing bases, the following pH buffer solutions were prepared as deodorizing bases and deodorizing performance tests were conducted. Test Example 1: 0.1 M citric acid and 0.1 M trisodium citrate were mixed to prepare a citrate buffer solution of pH 4.1. Test Example 2: 0.1 M acetic acid and 0.1 M sodium acetate were mixed to prepare an acetate buffer solution of pH 5.9. Test Example 3: 0.1 M sodium bicarbonate and 0.1 M sodium carbonate were mixed to prepare a carbonate buffer solution of pH 8.7.

[0082] Using the prepared buffer solution, a deodorization test was carried out.

[0083] <Deodorization test>

[0084] For each of the basic malodors, ammonia and trimethylamine, and the acidic malodors, methyl mercaptan and acetic acid, malodor solutions of the following concentrations were prepared using reagents and ion-exchanged water. Ammonia water: 25% ammonia water (reagent grade 1 [manufactured by Wako Pure Chemical Industries, Ltd.]) was diluted to prepare 2.5% ammonia water. Trimethylamine water: 30% trimethylamine solution (Wako Pure Chemical Industries, Ltd.) was diluted to prepare 2.5% trimethylamine water. Methyl mercaptan sodium hydroxide solution: 15% methyl mercaptan sodium hydroxide solution (Tokyo Chemical Industry Co., Ltd.) was diluted to prepare 1.25% methyl mercaptan sodium hydroxide solution. Acetic acid water: 10% acetic acid water was prepared by diluting acetic acid (Wako Pure Chemical Industries, Ltd., special grade).

[0085] A glass petri dish with an inner diameter of 80 mm was placed in the center of a magnetic plate in a 19 L vacuum polycarbonate desiccator equipped with a cock, and cut cotton 4 cm square (manufactured by Nisshin Medical Equipment Co., Ltd.) was placed in the glass petri dish.

[0086] The malodorous solution was dropped onto the cotton pad, and immediately thereafter, 0.5 ml of the prepared deodorant base was dropped onto the area where the malodorous solution had been dropped.

[0087] After the deodorant base was dripped, the desiccator was immediately covered with a lid and the lid and body were fixed at four points using separable clamps to ensure airtightness.

[0088] After 30 minutes had passed in that state, a detector tube (manufactured by Gastec Corporation) for measuring the concentration of malodor was inserted into the silicon tube attached to the cock, and the gas in the desiccator was sucked in to measure the concentration of malodor in the desiccator. The deodorization test was carried out with the room temperature adjusted to 20°C.

[0089] The deodorization test according to the above procedure was carried out 12 times for each prepared malodorous solution (ammonia water, trimethylamine water, methyl mercaptan soda water, acetic acid water) and for each deodorizing base (Test Examples 1 to 3), and the malodorous concentration was measured for each. The amount of the malodorous solution dropped onto the cut cotton was 91μl for ammonia water, 70μl for trimethylamine water, 50μl for methyl mercaptan soda water, and 75μl for acetic acid water.

[0090] Furthermore, for each malodor solution, a blank (malodor concentration without adding a deodorant base) was measured. The blank measurement was performed in the same manner as above, except that the deodorant base was not added after the malodor solution was dropped onto the cotton pad.

[0091] The concentration of the malodorous solution and the amount of the malodorous solution dropped were set so that the malodorous concentration in the desiccator after 30 minutes in a blank state was approximately 100 ppm ammonia, 28 ppm trimethylamine, 8 ppm methyl mercaptan, and 10 ppm acetic acid. This is in accordance with the initial malodorous concentration in the SEK Mark textile product certification standard.

[0092] However, since the blank odor concentration varies depending on the temperature and humidity at the time, the odor eliminating rate was calculated according to the following formula using the blank odor concentration measured under the environmental conditions at the time of the test as the standard.

[0093] Deodorization rate (%) = [(blank odor concentration - odor concentration after deodorizing base is added) / blank odor concentration] x 100

[0094] The results of the deodorization rate in each deodorization test, that is, the deodorizing performance against each malodor of the pH buffer solutions of Test Examples 1 to 3, are shown in Table 1.

[0095] [Table 1]

[0096] As shown in Table 1, 0.1 M citrate buffer solution exhibited excellent deodorizing performance, particularly against ammonia and trimethylamine, which are basic malodors.

[0097] (2) Test Example 4

[0098] Deodorizing tests were conducted in the same manner as in Test Examples 1 to 3, except that the pH buffer solution as the deodorizing base in Table 1 was replaced with the ion-exchanged water shown in Table 2 and a 0.5% by weight (pure or as-is) aqueous solution of each deodorizing base shown by chemical name and product name in Table 2.

[0099] The results of the deodorizing rate in each deodorizing test, that is, the deodorizing performance of each deodorizing base against each malodor, are shown in Table 2.

[0100] [Table 2]

[0102] As shown in Table 2, amphoteric surfactants (especially lauryl acetate betaine and laurylamine oxide), cationic surfactants, polyphenols such as green tea extract and grape seed extract, and cyclodextrin demonstrated excellent deodorizing performance against the acidic acetic acid odor.

[0103] (3) Test Example 5

[0104] (Contact deodorization test of odor-eliminating liquid)

[0105] As deodorizing bases, ion-exchanged water and pH buffer solutions shown in Table 3, as well as 0.5% by weight (pure or as-is) aqueous solutions of each deodorizing base (except for grape seed extract among the deodorizing bases in Table 2) whose chemical names and product names are shown in Table 3 were used, a commercially available carpet (Pita Mat Loop [trademark] manufactured by Watanabe Kogyo Co., Ltd.) cut to 4 cm x 4 cm was used instead of cut cotton, and deodorizing tests were conducted in the same manner as in Test Examples 1 to 3, except that only ammonia water was used as the malodorous solution.

[0106] The results of the deodorizing rate in each deodorizing test, that is, the deodorizing performance of each deodorizing base when it came into contact with a malodor (ammonia), are shown in Table 3.

[0107] (Wipe and deodorize test of odor-eliminating liquid)

[0108] The deodorization test was conducted in the same manner as above (malodor / deodorizing liquid contact deodorization test), except that instead of "dropping 0.5 ml of deodorizing base onto the area of ​​the carpet cut to 4 cm x 4 cm where the malodor solution had been dripped," "the area of ​​the carpet cut to 4 cm x 4 cm where the malodor solution had been dripped (the area soaked in the malodor solution) was wiped back and forth twice with a deodorizing base sheet."

[0109] The deodorant base sheet (sheet-like product) used was a spunlace nonwoven fabric (40% rayon, 60% polyester, 45 g / m 2 ) was cut to 200 mm x 300 mm to form a single (single-layer) sheet (sheet-like substrate) weighing 2.7 g, on which 2.7 times the amount (7.3 g) of each deodorant base liquid used in the above (contact deodorant test of malodor / deodorant liquid) was uniformly held in a moist state.

[0110] The results of the deodorizing rate in each deodorizing test, that is, the deodorizing performance of each deodorizing base sheet against a malodor (ammonia) during wiping, are shown in Table 3.

[0111] [Table 3]

[0112] Furthermore, the correlation between the deodorizing rate when contacting with the deodorizing base liquid shown in Table 3 and the deodorizing rate when wiping with the deodorizing base sheet is shown in FIG.

[0113] As shown in Table 3, the deodorizing rate of the wiping operation of the deodorizing base sheet, which is kept wet with the deodorizing base liquid, is higher than the deodorizing rate of the contact between the liquids, ammonia water and the deodorizing base liquid. This is presumably because the malodorous substances themselves are physically removed by the wiping operation. Furthermore, as shown in Figure 1, a correlation (correlation coefficient 0.741) was confirmed between the deodorizing effect of contact between liquids and the deodorizing base sheet for wiping, and it was found that in addition to the physical removal of malodorous substances by wiping, the deodorizing base interacts chemically and physically with malodorous substances that were not wiped away by the wiping operation, resulting in an excellent deodorizing effect. EXAMPLES

[0114] (1) Examples 1 to 7 and Comparative Examples 1 to 8

[0115] As Examples 1 to 7, deodorizing and disinfecting cleaning agents having the compositions shown in Table 4 were prepared.

[0116] In addition, as Comparative Examples 1 to 8, deodorizing and disinfecting cleaners having the compositions shown in Table 5 were prepared.

[0117] The preparation methods or manufacturers of the components used in each of the Examples and Comparative Examples are as follows. 0.2 M citrate buffer: A 0.2 M citric acid solution and a 0.2 M trisodium citrate solution were mixed to prepare a citrate buffer of pH 4.1. Both the citric acid and trisodium citrate were reagents manufactured by Wako Pure Chemical Industries, Ltd. Cationic surfactant: Nissan Cation F2-50R manufactured by NOF Corporation was used as benzalkonium chloride, and Lonzabac 12 manufactured by LONZA Corporation was used as trialkylamine. Amphoteric surfactant: Amogen SH manufactured by Daiichi Kogyo Seiyaku Co., Ltd. was used as lauryl acetate betaine, and Unisafe A-LM manufactured by NOF Corporation was used as lauryl amine oxide.

Nonionic surfactant: Mydol 12 manufactured by Kao Corporation was used as lauryl glucoside. Persimmon tannin: Pansil FG-300 manufactured by Release Scientific Industry Co., Ltd. was used.

[0118] For the deodorizing and disinfecting cleaning agents prepared as Examples 1 to 7 and Comparative Examples 1 to 8, the pH after preparation was measured, and deodorizing tests were conducted in the same manner as in Test Examples 1 to 3 against acetic acid and methyl mercaptan, which have acidic odors that 0.1 M citrate buffer is somewhat weak against.

[0119] The results for Examples 1 to 7 are shown in Table 4 together with the results of Test Example 1, and Comparative Examples 1 to 8 are shown in Table 5.

[0120] [Table 4]

[0121] [Table 5]

[0122] As shown in Tables 4 and 5, the deodorizing and disinfecting cleaners (Examples 1, 2, 5, and 7) in which green tea extract, amphoteric surfactant, and cationic surfactant were added to 0.1 M citrate buffer (pH 4.1) showed better deodorizing performance against acidic odors than the comparative examples. Furthermore, the disinfecting and deodorizing cleaners (Examples 3, 4, and 6) in which various cyclodextrins were added to the formulation of Example 1 also showed better deodorizing performance than the comparative examples.

[0123] (2) Examples 8 and 9

[0124] A deodorizing and disinfecting cleaner having the composition shown in Table 6 was prepared using 0.2 M citric acid buffer, a cationic surfactant, an amphoteric surfactant, green tea extract, cyclodextrin, ethanol, and ion-exchanged water.

[0125] 100 ml of the obtained deodorizing, disinfecting, and cleaning liquid was placed in a trigger spray container (a Fresh Breeze [trademark] spray container, manufactured by Yamazaki Sangyo Co., Ltd.) and subjected to an evaluation test.

[0126] In addition, the spunlace nonwoven fabric described in Test Example 5 (40% rayon, 60% polyester, 45 g / m 2 ) was cut to 200 mm x 300 mm and weighing 2.7 g, and 2.7 times the amount (7.3 g) of the prepared deodorizing and disinfecting cleaning solution was applied to the sheet in a uniformly moist state to prepare a deodorizing and disinfecting cleaning sheet, which was then used for evaluation testing.

[0127] The evaluation tests for each product were carried out as follows for deodorizing performance, cleaning power, finish, sterilization performance, and antiviral properties. The results are shown in Table 6.

[0128] (2-1) Deodorizing performance evaluation test

[0129] (a) Contact deodorization test and wipe deodorization test

[0130] For each of the malodor solutions, ammonia water, trimethylamine water, methyl mercaptan soda water, and acetic acid water, a contact deodorization test and a wipe deodorization test were conducted in the same manner as in Test Example 5, and the deodorization rates for each were recorded as the contact deodorization rate and the wipe deodorization rate.

[0131] (b) Indirect contact deodorization test

[0132] In order to evaluate the deodorizing performance of the deodorizing liquid when the volatile odor is in contact with the deodorizing liquid without direct contact between the odor solution and the deodorizing base, the following indirect contact deodorizing test of the odor / deodorizing liquid was conducted.

[0133] That is, instead of cut cotton, a commercially available carpet (Pita Mat Loop, manufactured by Watanabe Kogyo Co., Ltd.) cut into 4 cm x 4 cm pieces was used, Instead of "Drop the malodorous solution, and immediately after that, drop 0.5 ml of deodorant base onto the area where the malodorous solution was dropped," the procedure reads, "Place a piece of P tile with about 0.5 g of deodorant, disinfectant, and cleaning solution on its top surface 4 cm away from a glass dish placed in the center on a magnetic plate in a desiccator, and immediately after that, drop the malodorous solution onto the carpet inside the glass dish." and, The odor concentration in the desiccator is measured by inserting a detector tube into the silicon tube attached to the cock and aspirating the gas in the desiccator after 120 minutes have passed, not after 30 minutes, with the desiccator lid closed to ensure airtightness. Except for the above, the same treatment as in Test Examples 1 to 3 was carried out to carry out an indirect contact deodorization test of the malodor / deodorizing liquid for each malodor solution of ammonia water, trimethylamine water, and methyl mercaptan soda water.

[0134] The P-tile pieces were PRD-401 vinyl floor tiles manufactured by Tajima Roofing Co., Ltd., cut to 6cm x 6cm. In Example 8, a P tile piece was used on which a deodorizing and disinfecting cleaning agent had been sprayed from a position 1 m away in advance in a different location to adhere about 0.5 g of the deodorizing and disinfecting cleaning agent to the upper surface, and the deodorizing rate was defined as the indirect contact deodorizing rate. In Example 9, a piece of P tile was used whose top surface had been previously wiped with a deodorizing and disinfecting cleaning sheet in a different location and about 0.5 g of a deodorizing and disinfecting cleaning solution had been applied to the top surface, and the deodorizing rate was recorded as the indirect wiping deodorizing rate.

[0135] In addition, a piece of P tile that had not had the deodorizing, disinfecting, and cleaning solution applied was placed in the same position, and the odorous solution was dropped onto the carpet in a glass petri dish to create a blank. The odor concentration in the desiccator was also measured after 120 minutes had passed with the desiccator lid closed to ensure airtightness.

[0136] The formula for calculating the deodorizing rate is: Deodorization rate (%) = [(blank odor concentration - odor concentration with P tile with deodorizing and disinfecting cleaning solution applied) / blank odor concentration] x 100 It is. (2-2) Cleaning evaluation test

[0137] An evaluation was conducted on the ability to remove oil stains that had accumulated around the kitchen of an average household, particularly around the ventilation fan top and gas stove.

[0138] For the deodorizing and disinfecting cleaners contained in trigger spray containers, cleaning properties were evaluated by spraying the deodorizing and disinfecting cleaner onto a soiled surface and rubbing the surface with a paper towel.

[0139] In addition, the deodorizing and disinfecting cleaning sheet that had been moistened with the deodorizing and disinfecting detergent was evaluated for cleaning ability by directly wiping a dirty surface with the sheet.

[0140] The cleaning ability was evaluated according to the following criteria. ◎: Deposited oil stains could be removed simply by rubbing lightly. ○: By rubbing a little harder, the deposited oily stains could be removed. △: By rubbing hard, some of the deposited oily stains could be removed. ×: Even when scrubbed strongly, the deposited dirt could hardly be removed. (2-3) Finishing evaluation test

[0141] The finish was evaluated using a square glass plate measuring 200 mm x 200 mm and 5 mm thick that had been thoroughly washed and dried.

[0142] The deodorizing and disinfecting cleaner in a trigger spray container was sprayed twice onto a glass plate (0.75 g / spray x 2 sprays = 1.5 g), the entire glass surface was wiped clean with a paper towel, and then the glass surface was left to dry at room temperature for 30 minutes, after which any residue remaining on the glass surface was visually evaluated.

[0143] In addition, for the deodorizing and disinfecting cleaning sheets that had been moistened with the deodorizing and disinfecting detergent, the sheets were directly used to wipe the entire glass surface, and then the sheet was left to dry at room temperature for 30 minutes, after which the glass surface was visually evaluated for any residue remaining.

[0144] The finish was evaluated according to the following criteria. ⊚: Even when the glass plate is held up to the light, no wiping residue is observed. ○: Even when the glass plate is held up to the light, only slight wiping marks are observed, which are hardly noticeable. △: When the glass plate is held up to the light, some wiping residue can be seen. The wiping residue can be seen even from a distance, which is bothersome. ×: Unwiped areas are observed even without holding the surface up to the light. This is to the extent that wiping with a dry cloth twice is required. (2-4) Bactericidal evaluation test

[0145] 4.5 ml of a deodorizing and disinfecting cleaning agent (hereinafter referred to as "Liquid A") contained in a trigger spray container, and 4.5 ml of a deodorizing and disinfecting cleaning agent (hereinafter referred to as "Liquid B") squeezed under pressure from a deodorizing and disinfecting cleaning sheet that had retained the deodorizing and disinfecting cleaning agent in a wet state, were each kept at 25°C.

[0146] On the other hand, Staphylococcus aureus (S. aureus), Escherichia coli (E. coli) and Pseudomonas aeruginosa (P. aeruginosa) were mixed in equal amounts and diluted 100 times. 6 A mixed bacterial stock solution of the three strains was prepared at cfu / ml.

[0147] 0.5 ml of the three-type mixed bacterial mother liquid was added to 4.5 ml each of solution A and solution B, and the mixture was stirred for 10 seconds in a test tube mixer. After leaving it for 50 seconds (contact time between the deodorizing and disinfecting liquid and the bacterial liquid was 1 minute), 0.5 ml was immediately taken from the mixture and mixed and stirred with 4.5 ml of SCD medium containing an inactivating agent (LP solution: lecithin / polysorbate 80 = 1.5% / 5%) to stop the bactericidal reaction.

[0148] As reaction stopping solutions, 1.0 ml of each of the three types of solutions, namely the original solution, a 100-fold dilution solution, and a 10,000-fold dilution solution (all prepared using physiological saline as the dilution solution), was smeared onto each petri dish containing SCDLP medium (Soybean Casein Digest Agar with Lecitin, polysorbate 80), and after culturing in a constant temperature bath at 37°C for 24 hours, the number of colonies was counted.

[0149] As a blank (untreated), physiological saline was used instead of solutions A and B, and the same procedure was carried out, followed by culturing in a constant temperature bath at 37° C. for 24 hours, after which the number of colonies was counted.

[0150] From the measurement results, the disinfecting activity value was calculated based on the following formula. Sterilization activity value: log (number of viable bacteria in blank) - log (number of viable bacteria in solution A or solution B)

[0151] In this test, a disinfectant is considered effective if its disinfecting activity value is 2 or higher. (2-5) Antiviral evaluation test

[0152] An external organization (QTEC) was commissioned to conduct antiviral testing on a deodorizing and disinfecting cleaning agent that was squeezed out under pressure from a moistened deodorizing and disinfecting cleaning sheet.

[0153] Test Overview Test virus: Influenza A virus (H3N2) Host cells: MDCK cells (canine kidney-derived cells) Target sample: phosphate buffered saline (hereinafter referred to as PBS) Test sample: Deodorizing and disinfecting cleaning liquid squeezed out from a deodorizing and disinfecting cleaning sheet Test conditions: action temperature 25℃, action time 1 minute Drug inactivation agent: SCDLP medium Infectivity titer measurement method: Plaque measurement method

[0154] Test Method

[0155] 1) Host cell validation test

[0156] 1)-1 Cytotoxicity confirmation test 1. Add 0.1 ml of the test sample to 0.9 ml of SCDLP medium and mix. 2. Prepare a 10-fold serial dilution of the resulting mixture using EMEM (Eagle's minimal essential medium). 3. Cells are stained in the same manner as in the plaque assay method, and the presence or absence of cytotoxicity is confirmed.

[0157] 1)-2 Test to confirm cell susceptibility to viruses 1. Add 0.5 ml of test sample to 4.5 ml of SCDLP medium and mix. 2. Prepare a 10-fold serial dilution of the resulting mixture using EMEM (Eagle's minimal essential medium). 3.4 to 6×10 4 Add 1 / 100 of the test virus suspension adjusted to PFU / ml of each dilution series from step 2. 4. Leave at room temperature for 10 minutes. 5. Measure the viral infectivity using the plaque assay to confirm the susceptibility of cells to the virus.

[0158] The above confirmation test will be conducted if the following criteria are met. 1) -1: No cytotoxicity 1)-2: Confirmation of cell susceptibility to the virus: log (virus infectivity of PBS (PFU / ml)) - log (virus infectivity of test sample (PFU / ml)) ≦ 0.5

[0159] 2) Main Test 1. Host cells are infected with the virus, cultured, and then centrifuged to remove cell debris, and the resulting virus suspension (>10 8 PFU / ml). 2. Add 0.1 ml of the virus suspension to 0.9 ml of the test sample and leave at 25°C for 1 minute. This is the test solution. 3. Inactivate the test solution under conditions that have been confirmed to be inactivated in the host cell verification test. This is the reaction stop solution. 4. 10 ml of the reaction stop solution from step 3 above 0 A 10-fold serial dilution is made with EMEM, the virus infectivity per 0.1 ml of the reaction stop solution is measured by plaque assay, and the virus infectivity per 1 ml of the test solution is calculated.

[0160] The antiviral activity value is calculated according to the following formula. Antiviral activity value = log(Vb) - log(Vc) [Wherein, (Vb) is the virus infectivity of the control sample (PBS), and (Vc) is the virus infectivity of the test sample]

[0161] In this test, an antiviral activity value of 2 or higher is considered effective, and a value of 3 or higher is considered sufficiently effective.

[0162] [Table 6]

[0163] As shown in Table 6, the deodorizing and disinfecting cleaning agent of Example 8 (in a trigger spray container) and the deodorizing and disinfecting cleaning sheet of Example 9 (which retains the deodorizing and disinfecting cleaning agent wet) exhibited good deodorizing performance across a range of odors from basic to acidic.

[0164] In addition, the results of the indirect contact deodorization rate and indirect wiping deodorization rate in the indirect contact deodorization test shown in Table 6 indicate that the deodorizing ingredients can act on the evaporated malodorous molecules and exert a deodorizing effect even if the deodorant liquid does not come into direct contact with the malodorous substances. This indicates that, for example, by cleaning and wiping hard surfaces such as floors and walls, not only the malodorous substances present on the surface but also the malodorous molecules floating in the air are chemically or physically deodorized when they come into contact with the hard surfaces to which the deodorant base has been attached by cleaning and wiping.

[0165] Table 6 also shows that by combining each component in a specified blend ratio, both excellent cleaning efficiency and finishing properties can be achieved, and that by blending a specified amount of cationic surfactant, good disinfecting performance can be achieved.

[0166] Furthermore, the antiviral activity value of Example 9 in Table 6 indicates that the deodorizing and disinfecting cleaning agent (squeezed out of the deodorizing and disinfecting cleaning sheet by pressure) has an excellent effect of reducing the infectivity of the influenza virus.
