Abstract

To provide an electron donor visualization kit and an electron donor visualization method capable of stably visualizing electron donors such as urine components and trace protein components over a certain period.SOLUTION: An electron donor visualization kit is obtained by combining a solution A comprising an electron donating colorant and a solvent, and a solution B containing a bleaching component comprising an electron acceptor and a solvent. The liquid A or B contains a specific surfactant that has an N-C bond with a high electron density in a molecular structure. Since a connection part of this surfactant is cut by an electron acceptor to form a micelle that incorporates a dye inside, an area other than the surface on which electron donors adhere is rapidly decolored. Therefore, by coloring an adhesion area of the electron donors and decolorizing the other area, the adhesion area can be stably visualized for a certain period.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to an electron donor visualization kit capable of visualizing urinary components and other electron donors, and a method for visualizing electron donors using the same. [Background technology]

[0002] Urine components easily scatter on toilet floors and walls, and if left unattended, they can be decomposed by bacteria and cause unpleasant odors such as ammonia. Protein components such as milk, sweeteners, and juices also easily scatter around the kitchen and dining table, causing stains and odors if left unattended. For this reason, cleaning is carried out periodically or as needed, but these deposits are nearly transparent, making them difficult to see with the naked eye after drying. Therefore, even after cleaning, it is impossible to confirm whether they have been completely removed, and as a result, many people feel that odors do not go away even after cleaning.

[0003] Countermeasures include replacing wallpaper and installing air purifiers, but these are quite costly. Therefore, in many cases, people simply ventilate the room or install air fresheners or deodorizers. However, these measures do not remove the source of the dirt or odor, so their effectiveness is limited.

[0004] Patent Document 1 discloses a cleaning composition containing a dye that stains proteins and a surfactant that removes dirt. This cleaning composition allows the dye to reveal protein-adhering sites, which can then be cleaned with the surfactant. However, the stained areas are also bleached by the cleaning components, which means the color cannot be maintained for a certain period of time, making it difficult to ensure stability. Furthermore, the composition only visualizes protein components, and when sprayed onto walls, it is prone to dripping, which can lead to dye adhesion and a poor appearance. Patent Document 2 also discloses a liquid bleaching composition containing a colorant with an indicator function. However, this composition stains the entire sprayed area, and it takes about 15 minutes for the color to disappear, limiting the speed of cleaning work. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Special Publication No. 7-504699 [Patent Document 2] Japanese Patent Application Laid-Open No. 2001-294898 Summary of the Invention [Problem to be solved by the invention]

[0006] The object of the present invention is to solve the above-mentioned conventional problems and to provide an electron donor visualization kit and electron donor visualization method that can stably visualize the coloration of the adhesion site of an electron donor such as a urine component or a trace protein component over a certain period of time, and that rapidly decolorizes areas other than the adhesion site and is less likely to cause dripping. [Means for solving the problem]

[0007] The electron donor visualization kit of the present invention, which has been made to solve the above-mentioned problems, is an electron donor visualization kit that combines Solution A, which consists of an electron-donating colorant and a solvent, with Solution B, which contains a bleaching component consisting of an electron acceptor and a solvent, and is characterized in that Solution A or Solution B contains one or more surfactants selected from the compounds represented by the following formula 1 or 2: In these formulas, R is an alkyl or alkenyl group having 8 to 24 carbon atoms, X is an N atom or CO-N, A is an alkyl or oxyalkylene group having 2 to 4 carbon atoms, M is NH4 or HN(C2H4OH)3, n and m in Chemical 1 are 0 or integers of 1 or more (excluding both being 0), and n in Chemical 2 is an integer from 0 to 10.

[0008] [ka]

[0009] [ka]

[0010] It is preferable that the solution A contains at least one selected from the group consisting of acid clay, activated clay, kaolin, bentonite, diatomaceous earth, perlite, and smectite. According to a preferred embodiment, the electron donor is a urine component, and the kit is used as a urine component visualization kit.

[0011] The method for visualizing an electron donor of the present invention, which has been made to solve the above-mentioned problems, is a method for visualizing an electron donor using the above-mentioned electron donor visualization kit, characterized in that the electron donor is visualized by spraying the above-mentioned Solution A and Solution B onto the electron donor. According to a preferred embodiment, the electron donor is a urinary component. [Effects of the Invention]

[0012] The electron donor visualization kit of the present invention consists of Solution A, which consists of an electron-donating colorant and a solvent, and Solution B, which contains a bleaching component consisting of an electron acceptor and a solvent. By bleaching areas other than those where electron donors, such as urine components and trace protein components, are attached, the kit can stably visualize only the attached areas for a certain period of time. Furthermore, by including a specific surfactant in Solution A or Solution B, dripping is less likely to occur when sprayed onto a wall surface, and the decolorization rate of the electron-donating colorant sprayed on a surface where no electron donors are attached is increased. [Brief explanation of the drawings]

[0013] [Figure 1] FIG. 1 is an explanatory diagram showing the function of a surfactant in the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0014] The embodiments of the present invention will be described below. First, the principle of visualization of the electron donor of the present invention will be described. First, when Liquid B, which contains a bleaching component consisting of an electron acceptor and a solvent, is sprayed onto a surface with urine components attached, the bleaching component reacts with the urine components (electron donors) and reduces the bleaching ability, but there is no reduction in bleaching ability in areas where the electron donor is not attached. Next, when Liquid A, which contains an electron-donating colorant and a solvent, is sprayed on top of that, the electron-donating colorant is bleached and decolorized in areas where the bleaching ability is not reduced, becoming colorless. However, the electron-donating colorant is not decolorized in areas where the bleaching ability has been reduced by reaction with the urine components. Therefore, only the areas with urine components attached are colored, and can be stably visualized for a certain period of time. Liquid A may be sprayed before or at the same time as Liquid B.

[0015] Electron donors that can be visualized include proteins made up of amino acids, and sweeteners and juices containing glucose and dextrose. The amino groups of amino acids and the ether groups of glucose and dextrose are electron donors that are easily oxidized, and urine components can also be visualized because they contain proteins. In addition, compounds with high electron density (δ-) such as C=C, C=N, CN (including peptide bonds), -NH2, -NH-, and -SH are easily oxidized. Therefore, in addition to starch urinary components, it is possible to visualize compounds such as proteins, amino acids, and sugars.

[0016] Solution A consists of an electron-donating colorant and a solvent. Electron-donating colorants are colorants that easily lose electrons and are oxidized. This property applies to all dyes, including acidic and basic dyes. Examples of acidic dyes include nitroso dyes, nitro dyes, monoazo dyes, diazo dyes, triphenylmethane dyes, xanthene dyes, anthraquinone dyes, indigoid dyes, and aminoketone dyes. Examples of basic dyes include diphenylmethane dyes, acridine dyes, methine dyes, thiazole dyes, azine dyes, and thiazine dyes. Other examples of dyes that can be used include triazo dyes, polyazo dyes, quinoline dyes, oxazine dyes, carotenoid dyes, indophenol dyes, hydroxyketone dyes, anthocyanin dyes, alizarin red S, and borothymol. The content of the electron-donating colorant is preferably 10 ppm to 10 wt %, and more preferably 100 ppm to 1 wt %.

[0017] The solvent may be water such as ion-exchanged water, pure water, or tap water, or an organic solvent. Examples of the organic solvent include alcohols such as methanol, ethanol, propanol, butanol, pentanol, hexanol, and benzyl alcohol, and diols or triols such as glycerin, diglycerin, triglycerin, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, and polyethylene glycol, used alone or in combination. The amount of the organic solvent added is preferably 60 to 99.99% by weight.

[0018] The electron acceptor contained in Solution B is an oxidizing agent that oxidizes a counter substance by accepting electrons, and can be selected from the group consisting of metal hypochlorites such as sodium hypochlorite, metal chlorates, hydrogen peroxide, metal perborates, metal percarbonates, metal peroxides, acyl peroxides, benzoyl peroxide, peracetic acid, ozone, sodium bisulfate, nitrogen dioxide, chlorine, chlorine dioxide, azodicarbonamide, sodium sulfite, sodium metabisulfite, percarbonates, tetraacetyleneethylenediamine, metal peroxymonosulfates, and mixtures thereof. The content of the electron acceptor is preferably 10 ppm to 20 wt%, and more preferably 100 ppm to 6 wt%.

[0019] In the present invention, Solution A or Solution B contains one or more surfactants selected from the compounds represented by the formula 1 or 2. The surfactant content is preferably 10 ppm to 20 wt %, and more preferably 100 ppm to 5 wt %. The compound shown in Chemical Formula 1 is a compound in which an alkyl or alkenyl group having 8 to 24 carbon atoms, or an alkyl or oxyalkylene group having 2 to 4 carbon atoms is bonded to the N atom or CO-N shown as X. Representative examples include polyoxyethylene stearylamine ether, polyoxyethylene alkylamine, and alkylalkanolamide.

[0020] The compound shown in Chemical Formula 2 is (CH2CH2O) n It is a compound in which a hydrophilic group represented by R and a hydrophilic group represented by SO3M are bonded to both ends of a hydrophilic group such as ethylene glycol represented by (2). M is a counter ion (NH4 or HN(C2H4OH)3). Representative compounds of Chemical Formula 2 are ammonium lauryl sulfate, triethanolamine lauryl sulfate, and polyoxyethylene alkyl ether triethanolamine sulfate.

[0021] As shown in the data in the Examples below, when these surfactants are added, electron-donating colorants sprayed on surfaces to which no electron donor has been attached quickly fade. Furthermore, the increased viscosity prevents dripping even when sprayed on a vertical wall. The mechanism of action of the surfactants in the present invention is believed to be as follows.

[0022] As shown in the upper part of Figure 1, the surfactant used in the present invention has a N-C bond with high electron density in its molecular structure. This bond is formed by Cl released from the electron acceptor contained in Solution B, such as sodium hypochlorite. + The bond is broken by the removal of an electron. When the surfactant's bond is broken, it forms a quaternary ammonium salt cation, as shown in the middle of Figure 1. When the surfactant is polyoxyethylene stearylamine ether, the quaternary ammonium salt cation formed is hexadecyltrimethylammonium chloride. This has hydrophilic and hydrophobic groups at both ends of the molecule, forming micelles with hydrophilic groups on the outside and hydrophobic groups on the inside, as shown in the bottom of Figure 2. Dyes and bleaching ingredients are captured inside these micelles, resulting in localized concentration and accelerated bleaching. This mechanism of action cannot be achieved by using surfactants that do not have the electron-dense N-C bond portion.

[0023] It is preferable that the solution A contains at least one selected from the group consisting of acid clay, activated clay, kaolin, bentonite, diatomaceous earth, perlite, and smectite. These smectites and the like trap the dye inside, and the Cl released from hypochlorous acid is absorbed. + This prevents the bleaching action of smectite, improving the stability of dyes over time. Smectite is a general term for a group consisting of montmorillonite, a dioctahedral hydrous layered silicate mineral, and hydrite, nontronite, saponite, hectorite, sauconite, and stevensite, which have a similar structure to montmorillonite.

[0024] Additionally, known thickeners can be added to Solution A or Solution B to enhance adhesion. Examples of known thickeners include water-swellable silicate particles, alginate, carboxymethylcellulose, gum arabic, arginine polymer, sodium alginate, alginate propylene glycol, ethyl cellulose, xanthan gum, carrageenan, pectin, gellan gum, methylcellulose, polyvinylpyrrolidone resin, butyral resin, acrylic resin, and cellulose nanofiber. Water-swellable silicate particles such as smectite, bentonite, vermiculite, and mica are particularly desirable because they have high thixotropy and significantly reduce the viscosity of the liquid due to the pressure applied when the liquid passes through the fine holes in the nozzle during spraying, thereby improving liquid diffusion during spraying. The amount of thickener added is preferably 0.1 to 20% by weight.

[0025] It is preferable that Liquid A and Liquid B are filled in separate spray containers and sold as a kit. The visualization kit of the present invention refers to a tool used to visualize urine components, etc. by spraying Liquid A and Liquid B onto the surface of an electron donor, and the form of the visualization kit is not limited, and may be, for example, one or more spray containers, packs, collection tubes, syringes, etc. filled with Liquid A and Liquid B, respectively. The visualization kit may also be configured to be electrically driven using a sensor or power source, or may be configured like an aerosol in which the contents are sprayed in a mist by gas pressure.

[0026] As described above, to visualize electron donors using the electron donor visualization kit, liquids A and B are sprayed sequentially or simultaneously onto the surface of the electron donor. The areas where electron donors, such as urine components and trace protein components, are attached are colored with the colorant, while other areas quickly lose their color. Because the areas where the electron donor is attached can be visualized in this way, cleaning becomes easier. Another advantage is that no dripping occurs even when sprayed on a vertical wall. Examples and comparative examples are shown below. [Example]

[0027] Liquid A having the composition shown in Table 1 and liquid B having the composition shown in Table 2 were prepared. The solvent for all of the liquid A's was distilled water, and the electron-donating colorants were all anthraquinone dyes. In Examples 1-3 and 11-13, polyoxyethylene stearylamine ether represented by the formula (Chemical Formula 1) was added as a surfactant. In the other Examples, a surfactant listed in the table and represented by the formula (Chemical Formula 2) was added. In Comparative Example 1, no surfactant was added, and in Comparative Examples 2-3, a silicone-based surfactant was added that, unlike the surfactants shown in Chemical Formulas 1 and 2, does not have a high electron density N-C bond moiety.

[0028] The composition of Solution B is as shown in Table 2, with tap water as the solvent and sodium hypochlorite as the electron acceptor. Smectite, which is a water-swellable silicate particle, was added as a thickener, and sodium metasilicate was added as an alkaline agent. Solution B was the same for all of the Examples and Comparative Examples.

[0029] These solutions A and B were sprayed sequentially onto a wall surface to which the target component had been attached, and the coloring of the attached areas, the speed at which the color disappeared from the non-attached areas, dripping on the wall surface, and stability over time were evaluated, and the results are shown in Table 1.

[0030] In each example, discoloration of the adhered areas was confirmed, and the decolorization rate of the non-adhered areas was 1-1.5 minutes. In Examples 1-3, the amount of surfactant added was significantly changed, but similar effects were obtained. Visualization was possible not only for urine components, but also for milk containing protein components as in Example 10. None of the embodiments exhibited dripping, and the stability over time was good. In particular, Examples 1-4 and 9-10 exhibited a decolorization rate of 1 minute. In contrast, in the comparative examples, discoloration of the adhered areas was confirmed, but the decolorization rate was slow at 3 minutes in each case, and dripping also occurred in Comparative Examples 2-3.

[0031] [Table 1]

[0032] [Table 2]

[0033] As described above, according to the present invention, electron donors such as urine components and protein components can be stably visualized for a certain period of time. Furthermore, dripping is unlikely to occur when sprayed onto a wall surface, and the decolorization effect of the electron donor colorant sprayed on a surface to which no electron donor has adhered is accelerated, allowing for rapid cleaning work.
