Description

[Technical Field]

[0001] The present invention relates to a liquid deodorant composition and a deodorizing method using the liquid deodorant composition. [Background technology]

[0002] Deodorizers are sometimes used to combat odors in everyday life. The substances that cause odors vary depending on the target, and odors can sometimes be caused by multiple substances. For example, currently commonly used ethanol-based liquid deodorizers are effective against ammonia gas, but are less effective against methyl mercaptan and hydrogen sulfide. In addition, existing non-ethanol-based oxidizing liquid deodorizers, such as hypochlorous acid, are effective against a relatively large number of odor-causing substances, but have the problem of causing metal corrosion and discoloration of fabrics when sprayed on metals or fabrics.

[0003] Meanwhile, solid deodorizers such as solid chlorine agents are also known. For example, Patent Document 1 describes a solid halogen agent composition containing a solid halogen agent represented by the formula R-SO2NXM (wherein R represents a methoxyphenyl group, X represents a chlorine or bromine atom, and M represents an alkali or alkaline earth metal atom) and one or more solid acids selected from phosphoric acid, phosphonic acid, boric acid, oxalic acid, lactic acid, glycolic acid, malic acid, succinic acid, gluconic acid, citric acid, tartaric acid, benzoic acid, salicylic acid, fumaric acid, adipic acid, phthalic acid, terephthalic acid, maleic acid, itaconic acid, hydroxybenzoic acid, nitrilotriacetic acid, benzenesulfonic acid, toluenesulfonic acid, maleic anhydride, sodium hydrogen sulfate, potassium hydrogen sulfate, ammonium hydrogen sulfate, carbonic acid, and sulfamic acid. The solid halogen agent composition of Patent Document 1 is said to have a bactericidal effect in the vicinity of the area where it is installed, even though it does not directly contact the area.

[0004] In the examples of Patent Document 1, a solid halogen agent composition is used that combines N-chloro-p-methoxybenzenesulfonamide sodium as a specific compound of the above formula with sulfamic acid, benzoic acid, or fumaric acid as a solid acid. The solid halogen agent composition of Patent Document 1 is also suggested for use as a deodorizer, but its deodorizing effect has not been confirmed.

[0005] Because these solid chlorine agents are solid chemicals, they require the time-consuming task of dissolving the agent before they can be sprayed on the target area to be deodorized. Also, they are intended for use in kitchens, toilets, and bathrooms, making them difficult to use in entranceways, living rooms, bedrooms, etc.

[0006] As described above, solid deodorants have the problem that they require the time and effort of dissolving the agent in order to spray it on the target, making it difficult to spray on the target. Also, among liquid deodorants that can be used as a spray other than solid deodorants, there are few that are effective against multiple odor-causing substances, and hypochlorous acid-based liquid deodorants that are effective against a relatively large number of odor-causing substances have the problem of causing corrosion of metals and discoloration of fabrics.

DETAILED DESCRIPTION OF THE INVENTION

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following describes an embodiment of the present invention. The embodiment is an example of implementing the present invention, and the present invention is not limited to the embodiment.

[0019] <Liquid deodorant composition> The liquid deodorant composition according to an embodiment of the present invention is a liquid composition containing a bromine-based oxidizing agent and a sulfamic acid compound.

[0020] After extensive research, the inventors discovered that a liquid composition using a bromine-based oxidizing agent and a sulfamic acid compound has a deodorizing effect on as many odor-causing substances as possible and can suppress metal corrosion and fabric discoloration. This effect has not been achieved with existing liquid deodorizers, such as those based on ethanol, oxidizing agents such as hypochlorous acid, or slightly acidic electrolyzed water. Furthermore, because it is a liquid deodorizer rather than a solid deodorizer, it is suitable for users, including general consumers, to deodorize objects. For example, it can be filled into a spray bottle and sprayed on the object. Furthermore, even when sprayed on metal or fabric, it can suppress metal corrosion and fabric discoloration.

[0021] The phrase "comprising a bromine-based oxidizing agent and a sulfamic acid compound" may include a stabilized hypobromous acid composition containing a mixture of a "bromine-based oxidizing agent" and a "sulfamic acid compound," or may include a stabilized hypobromous acid composition containing a "reaction product of a bromine-based oxidizing agent and a sulfamic acid compound."

[0022] Examples of bromine-based oxidizing agents include bromine (liquid bromine), bromine chloride, bromic acid, bromates, hypobromous acid, etc. Hypobromous acid may be produced by reacting a bromine compound such as sodium bromide with a chlorine-based oxidizing agent such as hypochlorous acid.

[0023] Among these, compositions containing "bromine and a sulfamic acid compound (a mixture of bromine and a sulfamic acid compound)" or "a reaction product of bromine and a sulfamic acid compound" using bromine are more preferable as liquid deodorant compositions because they produce less bromic acid as a by-product and are less corrosive to metals and less bleaching to fabrics than compositions such as "a bromine compound, hypochlorous acid, and sulfamic acid."

[0024] Examples of bromine compounds include sodium bromide, potassium bromide, lithium bromide, ammonium bromide, and hydrobromic acid. Of these, sodium bromide is preferred from the viewpoint of formulation costs.

[0025] Examples of chlorine-based oxidizing agents include chlorine gas, chlorine dioxide, hypochlorous acid or its salts, chlorous acid or its salts, chloric acid or its salts, perchloric acid or its salts, and chlorinated isocyanuric acid or its salts. Among these, examples of salts include alkali metal hypochlorites such as sodium hypochlorite and potassium hypochlorite, alkaline earth metal hypochlorites such as calcium hypochlorite and barium hypochlorite, alkali metal chlorites such as sodium chlorite and potassium chlorite, alkaline earth metal chlorites such as barium chlorite, other metal chlorites such as nickel chlorite, alkali metal chlorates such as ammonium chlorate, sodium chlorate, and potassium chlorate, and alkaline earth metal chlorates such as calcium chlorate and barium chlorate. These chlorine-based oxidizing agents may be used alone or in combination of two or more. As the chlorine-based oxidizing agent, sodium hypochlorite is preferred from the viewpoint of ease of handling.

[0026] The sulfamic acid compound is a compound represented by the following general formula (1). R2NSO3H (1) (In the formula, R is independently a hydrogen atom or an alkyl group having 1 to 8 carbon atoms.)

[0027] Examples of sulfamic acid compounds include sulfamic acid (amidosulfuric acid) in which both R groups are hydrogen atoms, as well as sulfamic acid compounds in which one of the R groups is a hydrogen atom and the other is an alkyl group having 1 to 8 carbon atoms, such as N-methylsulfamic acid, N-ethylsulfamic acid, N-propylsulfamic acid, N-isopropylsulfamic acid, and N-butylsulfamic acid; sulfamic acid compounds in which both of the R groups are alkyl groups having 1 to 8 carbon atoms, such as N,N-dimethylsulfamic acid, N,N-diethylsulfamic acid, N,N-dipropylsulfamic acid, N,N-dibutylsulfamic acid, N-methyl-N-ethylsulfamic acid, and N-methyl-N-propylsulfamic acid; sulfamic acid compounds in which one of the R groups is a hydrogen atom and the other is an aryl group having 6 to 10 carbon atoms, such as N-phenylsulfamic acid; and salts thereof. Examples of sulfamic acid salts include alkali metal salts such as sodium salts and potassium salts, alkaline earth metal salts such as calcium salts, strontium salts and barium salts, other metal salts such as manganese salts, copper salts, zinc salts, iron salts, cobalt salts and nickel salts, ammonium salts and guanidine salts.Sulfamic acid compounds and their salts may be used alone or in combination of two or more.As the sulfamic acid compound, sulfamic acid (amidosulfuric acid) is preferably used from the viewpoint of environmental load.

[0028] The liquid deodorant composition according to this embodiment may contain an acid. Examples of the acid include inorganic acids such as sulfuric acid, hydrochloric acid, nitric acid, hydrogen iodide, perchloric acid, chloric acid, bromic acid, iodic acid, and perbromic acid. From the standpoint of safety, it is preferable to contain at least one acid selected from sulfuric acid, hydrochloric acid, and nitric acid. When an acid is contained, the content of the acid in the liquid deodorant composition is, for example, in the range of 0.001% by mass to 0.5% by mass, and preferably in the range of 0.01% by mass to 0.1% by mass. If the content of the acid in the liquid deodorant composition is less than 0.001% by mass or more than 0.5% by mass, the storage stability may be reduced.

[0029] The pH of the liquid deodorant composition is, for example, in the range of 5.0 to 11.0, preferably in the range of 6.0 to 10.0, and more preferably in the range of 6.5 to 9.5. If the pH of the liquid deodorant composition is less than 5.0, the storage stability may be reduced and halogen gas may be generated, whereas if it exceeds 11.0, the storage stability may be reduced.

[0030] The effective bromine concentration in the liquid deodorant composition is, for example, in the range of 0.01% to 0.25%, preferably in the range of 0.01% to 0.169%, and more preferably in the range of 0.01% to 0.113%. If the effective bromine concentration in the liquid deodorant composition is less than 0.01%, the deodorizing performance effect may be reduced, and if it exceeds 0.25%, discoloration of fabrics may occur.

[0031] In the liquid deodorant composition according to this embodiment, the ratio of the equivalents of the "sulfamic acid compound" to the equivalents of the "bromine-based oxidizing agent" is preferably 1.0 or more, more preferably in the range of 1.0 to 2.0, and even more preferably in the range of 1.05 to 1.5. If the ratio of the equivalents of the "sulfamic acid compound" to the equivalents of the "bromine-based oxidizing agent" is less than 1.0, the bromine concentration may be significantly reduced, and if it exceeds 2.0, the production cost may increase.

[0032] An alkali may be blended into the stabilized hypobromous acid composition. Examples of the alkali include alkali hydroxides such as sodium hydroxide and potassium hydroxide. From the viewpoint of product stability at low temperatures, sodium hydroxide and potassium hydroxide may be used in combination. The alkali may also be used as an aqueous solution instead of a solid.

[0033] The liquid deodorant composition according to this embodiment contains water as the balance of the above components. Examples of water include tap water, pure water, and ultrapure water.

[0034] The liquid deodorant composition according to the present embodiment is a liquid composition, and can be used by being filled, for example, in a spray-type container, a ballon box container, a container with a cap, etc. Among these, it is preferable that it be filled in a spray-type container, since it can be easily sprayed on an object to be deodorized.

[0035] <Method of manufacturing liquid deodorant composition> The liquid deodorant composition according to this embodiment can be obtained, for example, by mixing a bromine-based oxidizing agent, a sulfamic acid compound, and, if necessary, an acid with water, and an alkali may also be mixed in. The liquid deodorant composition according to this embodiment can be obtained, for example, by diluting a stabilized hypobromous acid composition obtained by mixing a bromine-based oxidizing agent, a sulfamic acid compound, and, if necessary, an alkali with water, and adding an acid as necessary to adjust the effective bromine concentration to, for example, 0.01% or more and 0.25% or less and the pH to a range of 5.0 to 11.0.

[0036] A method for producing a stabilized hypobromous acid composition containing bromine and a sulfamic acid compound preferably includes a step of adding bromine to a mixed solution containing water, an alkali, and a sulfamic acid compound under an inert gas atmosphere to cause a reaction, or a step of adding bromine to a mixed solution containing water, an alkali, and a sulfamic acid compound under an inert gas atmosphere. By adding and causing a reaction under an inert gas atmosphere or by adding under an inert gas atmosphere, the bromate ion concentration in the stabilized hypobromous acid composition is reduced.

[0037] The inert gas to be used is not limited, but from the viewpoint of production etc., at least one of nitrogen and argon is preferable, and from the viewpoint of production cost etc., nitrogen is particularly preferable.

[0038] The oxygen concentration in the reactor during the addition of bromine is preferably 6% or less, more preferably 4% or less, even more preferably 2% or less, and particularly preferably 1% or less. If the oxygen concentration in the reactor during the reaction of bromine exceeds 6%, the amount of bromic acid produced in the reaction system may increase.

[0039] The bromine content is preferably 25% by mass or less, more preferably 1% by mass or more and 20% by mass or less, based on the total amount of the stabilized hypobromous acid composition. If the bromine content exceeds 25% by mass based on the total amount of the stabilized hypobromous acid composition, the amount of bromate produced in the reaction system may increase. If the bromine content is less than 1% by mass, the antibacterial, disinfecting, sterilizing, or sterilizing effects may be inferior.

[0040] The reaction temperature during the addition of bromine is preferably controlled within a range of 0° C. to 25° C., but from the viewpoint of production costs, it is more preferably controlled within a range of 0° C. to 15° C. If the reaction temperature during the addition of bromine exceeds 25° C., the amount of bromic acid produced in the reaction system may increase, and if it is below 0° C., freezing may occur.

[0041] <Deodorizing method> The deodorizing method according to this embodiment is a method of deodorizing a deodorizing target using the liquid deodorizer composition. In this specification, "deodorization" in "liquid deodorizer composition" and "deodorizing method" means removing or reducing odor-causing substances in a certain substance or a limited space, etc., to eliminate or eliminate odors.

[0042] There are no particular limitations on the objects to be deodorized, and deodorization can be performed in, for example, homes (e.g., entrance halls, living rooms, bedrooms, kitchens, toilets, etc.), restaurants, factories, offices, pet shops, elderly care facilities, hospitals, etc. For example, deodorization can be performed on clothing, fabrics, tables, floors, etc.

[0043] The odors to be deodorized are not particularly limited, and examples include cigarette smoke, body odor, garbage odor, pet odor, feces odor, and urination odor. The liquid deodorant composition and deodorizing method according to this embodiment can be suitably applied to at least one of body odor, garbage odor, and pet odor. The liquid deodorant composition and deodorizing method according to this embodiment exhibit a uniform deodorizing effect on all of body odor, garbage odor, and pet odor.

[0044] The deodorizing method according to this embodiment is not particularly limited as long as it can deodorize or remove odors from an object to be deodorized. For example, the method can be carried out by spraying the object to be deodorized, by soaking a cleaning cloth or the like in the composition and wiping the object, or by diluting the liquid deodorizer composition and immersing the object to be deodorized in the diluted composition.

[0045] The odor-causing substance is not particularly limited as long as it is a substance that causes an odor. The odor-causing substance is not limited to malodorous substances. Examples of odor-causing substances include carboxylic acids such as acetic acid, butyric acid, and isovaleric acid, thiols such as hydrogen sulfide, methyl mercaptan, and 3-mercapto-3-methyl-1-butanol, and amines such as ammonia. The liquid deodorant composition and deodorizing method according to this embodiment can be suitably applied when the odor-causing substance is at least one of ammonia, acetic acid, butyric acid, methyl mercaptan, 3-mercapto-3-methyl-1-butanol, isovaleric acid, and hydrogen sulfide. The liquid deodorant composition and deodorizing method according to this embodiment exhibit a uniform deodorizing effect on ammonia, acetic acid, butyric acid, methyl mercaptan, 3-mercapto-3-methyl-1-butanol, isovaleric acid, and hydrogen sulfide.

[0053] EXAMPLES The present invention will be explained in more detail below with reference to examples and comparative examples, but the present invention is not limited to the following examples.

[0054] [Drug A: Preparation of stabilized hypobromous acid composition 1] A stabilized hypobromous acid composition was prepared by mixing 16.9% by weight (wt%) liquid bromine, 10.7% by weight sulfamic acid, 12.9% by weight sodium hydroxide, 3.94% by weight potassium hydroxide, and the remainder water under a nitrogen atmosphere. The pH of the stabilized hypobromous acid composition was 14, and the total chlorine concentration was 7.5% by weight. The total chlorine concentration was measured (mg Cl / L) using a HACH DR / 4000 multi-parameter water quality analyzer by the total chlorine measurement method (DPD (diethyl-p-phenylenediamine) method). The detailed preparation method of the stabilized hypobromous acid composition is as follows.

[0055] The nitrogen gas flow rate was continuously controlled with a mass flow controller to maintain the oxygen concentration in the reaction vessel at 1%, and 1436 g of water and 361 g of sodium hydroxide were added to a sealed 2 L four-neck flask. Then, 300 g of sulfamic acid was added and mixed. After mixing, 473 g of liquid bromine was added while maintaining cooling so that the reaction solution temperature was 0-15°C. Further, 230 g of 48% potassium hydroxide solution was added to obtain the desired stabilized hypobromous acid composition. The mass ratio of sulfamic acid to bromine was 10.7% and 16.9% by weight relative to the total composition, with an equivalent ratio of sulfamic acid to bromine of 1.04. The pH of the resulting solution was measured to be 14 by glass electrode method. The bromine content of the resulting solution was 16.9% when converted to iodine with potassium iodide and then measured by redox titration with sodium thiosulfate, which was 100.0% of the theoretical content (16.9%). The oxygen concentration in the reaction vessel during the bromine reaction was measured using an oxygen monitor JKO-02 LJDII manufactured by Jiko Co., Ltd. The bromate concentration was less than 5 mg / kg.

[0056] The pH was measured under the following conditions. Electrode type: Glass electrode pH meter: DKK Toa, IOL-30 Calibration of the electrode: Two-point calibration was performed using Kanto Chemical's neutral phosphate pH (6.86) standard solution (type 2) and the same company's borate pH (9.18) standard solution (type 2). Measurement temperature: 25℃ Measurement value: Immerse the electrode in the measurement solution, and use the value after stabilization as the measurement value, and take the average of three measurements.

[0057] [Test to confirm the effect on fabric (synthetic fiber)] Aqueous sodium hypochlorite solutions were prepared so that the effective bromine equivalent concentrations were 4.5% and 17%. Stabilized hypobromous acid compositions were also prepared in the same manner as the above-mentioned stabilized hypobromous acid composition so that the effective bromine equivalent concentrations were 4.5% and 17%.

[0058] (Test Method) [1] Cut a piece of synthetic fiber fabric (material: 100% polyester, stretch fabric) into 4cm x 4cm pieces. [2] 50 mL of each agent (4.5% sodium hypochlorite aqueous solution, 17% sodium hypochlorite aqueous solution, 4.5% stabilized hypobromous acid composition, 17% stabilized hypobromous acid composition, no agent (pure water)) was dispensed into polystyrene screw bottles. [3] Soak each cloth one by one. [4] Before and after immersion, the cloths were washed in pure water, and after 24 hours of immersion, they were allowed to air dry at 25°C for 24 hours. Then, photographs of their appearance were taken using the Fujifilm FinePix XP130 in auto mode. The photographs were then used to select colors and measure RGB values ​​using Microsoft Paint software. The results are shown in Table 1. While blue is represented as U in this software, it is represented as B in Table 1. Figure 1 also shows photographs of the appearance of each cloth (synthetic fiber) after 24 hours of immersion, rinsing, and drying.

[0059] [Table 1]

[0060] Compared to the aqueous solution of sodium hypochlorite, the stabilized hypobromous acid composition caused almost no discoloration of the fabric (synthetic fiber) and had almost no effect.

[0061] [Test to confirm the effect on fabric (cotton)] Aqueous sodium hypochlorite solutions were prepared so that the effective bromine equivalent concentrations were 0.056% and 0.225%. Stabilized hypobromous acid compositions were also prepared in the same manner as the above stabilized hypobromous acid composition so that the effective bromine equivalent concentrations were 0.056% and 0.225%.

[0062] (Test Method) [1] Cut the cotton fabric into 4cm x 4cm pieces. [2] 50 mL of each agent (0.056% sodium hypochlorite aqueous solution, 0.225% sodium hypochlorite aqueous solution, 0.056% stabilized hypobromous acid composition, 0.225% stabilized hypobromous acid composition, no agent (pure water)) was dispensed into polystyrene screw bottles. [3] Soak each cloth one by one. [4] Before and after immersion, the cloths were washed with pure water, and after 1 hour of immersion, they were allowed to air dry at 25°C for 24 hours, and then photographed for appearance. Figure 2 shows photographs of the appearance of each cloth (cotton) after immersion for 1 hour, washing with water, and drying.

[0063] Compared to the aqueous solution of sodium hypochlorite, the stabilized hypobromous acid composition caused almost no discoloration of the fabric (cotton) and had almost no effect.

[0064] Example 1 [Preparation of Liquid Deodorant Composition] Pure water was added at 99.526% by mass, and sodium bicarbonate was added at 0.1% by mass. Then, the above-mentioned stabilized hypobromous acid composition was added at 0.334% by mass, and then 62.5% by mass of sulfuric acid was added to adjust the pH to 8.5±1. Pure water was further added to adjust the total to 100% by mass, thereby preparing a liquid deodorant composition with an effective bromine concentration of 0.056% and a pH of 8.5±1.

[0065] <Example 2, Comparative Examples 1 and 2> [Deodorization test using a 5L gas bag] Each deodorant was sprayed into a 5L gas bag a predetermined number of times, and 3L of gas containing a predetermined concentration of odor-causing substances diluted with diluent gas was injected. After 30 minutes, the gas concentration was measured using a detector tube. The amount of remaining odor-causing substances was measured using a sensory method (olfactory measurement) for 3-mercapto-3-methyl-1-butanol gas only. The amount of remaining odor-causing substances was divided by the initial concentration to calculate the odor-causing substance reduction rate (odor component reduction rate) (%). Figure 3 shows the odor component reduction rate (%) for each of the deodorants in Example 2 and Comparative Examples 1 and 2 for various odor-causing substances.

[0066] (Test conditions) Dilution gas: N2 gas Gases containing odor-causing substances: Ammonia (initial concentration 86 mg / L, 6 sprays of deodorant), acetic acid (initial concentration 28 mg / L, 1 spray of deodorant), methyl mercaptan (initial concentration 7.3 mg / L, 6 sprays of deodorant), hydrogen sulfide (initial concentration 4 mg / L, 6 sprays of deodorant), isovaleric acid (initial concentration 7.5 mg / L, 1 spray of deodorant), 3-mercapto-3-methyl-1-butanol gas (initial concentration 3.7 mg / L, 1 spray of deodorant) Deodorizers: Liquid deodorizer composition of Example 1 (containing a stabilized hypobromous acid composition), aqueous sodium hypochlorite solution (effective bromine equivalent concentration 0.056%) (Comparative Example 1), ethanol-based deodorizer (containing 5 to 10% ethanol) (Comparative Example 2) Gas bag used: Smart Bag PA (manufactured by GL Sciences Inc.) Detector tubes used: Gastec Corporation 3La, 3L (ammonia), 4LT (hydrogen sulfide), 81L (acetic acid, isovaleric acid); Komyo Rikagaku Kogyo Co., Ltd. 130U (methyl mercaptan)

[0067] As can be seen from FIG. 3, the liquid deodorant composition of Example 1 was found to have a more uniform deodorizing effect on many odor-causing substances than the deodorants of Comparative Examples 1 and 2.

[0068] Example 3 [Deodorization test based on the voluntary standards of the Fragrance and Odor Elimination Council] In Example 3, data was obtained based on the voluntary standards for consumer fragrances, deodorizers, and deodorizers established by the Association of Deodorizers and Fragrances.

[0069] (Evaluation method) Test method: A 10 L gas bag was filled with the liquid deodorant composition of Example 1 at a predetermined concentration (concentration shown in the table) (in the case of a spray type, a predetermined amount was sprayed) and sealed, and odor-causing substances adjusted to predetermined initial concentrations (mg / L) shown in Tables 2 to 8 were then injected, and the concentration of the odor-causing substances was measured over time using a detector tube or a sensory method (olfactory measurement method) in the same manner as in Example 2. The results are shown in Tables 2 to 8. Gases containing odor-causing substances: isovaleric acid gas (Example 3-1), acetic acid gas (Example 3-2), hydrogen sulfide gas (Example 3-3), n-butyric acid gas (Example 3-4), methyl mercaptan gas (Example 3-5), 3-mercapto-3-methyl-1-butanol gas (Example 3-6), ammonia gas (Example 3-7) Deodorant: Liquid deodorant composition of Example 1 (containing stabilized hypobromous acid composition) Deodorizer spray amount: 3 sprays (0.78g, effective bromine equivalent concentration 0.056%) for isovaleric acid gas, acetic acid gas, and n-butyric acid gas; 8 sprays (2.08g, effective bromine equivalent concentration 0.056%) for hydrogen sulfide gas, methyl mercaptan gas, and 3-mercapto-3-methyl-1-butanol gas; 20 sprays (5.2g, effective bromine equivalent concentration 0.056%) for ammonia gas. Measurement time: 0.5, 1, 2, 4, 24 hours Judgment method: Time required to remove 90% of odor-causing substances when tested with a 10L gas bag (τ 0.1 ) must be within 10 hours (90% removal time is calculated using the formula below) Calculation formula: Malodorous substance generation suppression rate (%) = (malodorous concentration of sample / malodorous concentration of blank) x 100
