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. It explains that by using this cleaning composition, protein-adhered sites can be made visible by the dye and then cleaned by the surfactant. However, there is a risk that the dye adhering to sites where proteins are not attached will also develop a slight color over time, causing the entire surface to appear dirty.

Color reversion refers to the phenomenon in which a colorless area develops color over time. [Means for solving the problem]

[0007] The electron donor visualization kit of the present invention, which has been developed to solve the above-mentioned problems, is an electron donor visualization kit that combines liquid A, which contains a coloring component consisting of an electron-donating colorant and a solvent, and liquid B, which contains a bleaching component consisting of an electron acceptor and a solvent, and is characterized in that an alkali metal silicate is added to one or both of liquids A and B.

[0009] The electron donor visualization method of the present invention, which has been made to solve the above problems, comprises: thing A visualization method comprising: thing The A liquid and the B liquid are sprayed onto the adhesion area, and electrons are donated. thing This method for visualizing electron donors can be used to visualize urine components. [Effects of the Invention]

[0010] The electron donor visualization kit of the present invention comprises Solution A, which is composed of an electron donor colorant and a solvent, and Solution B, which contains a bleaching component composed of an electron acceptor and a solvent, and is capable of visualizing electron donors such as urine components and trace protein components. Furthermore, the alkali metal silicate added to either or both Solutions A and B acts to prevent color reversion of the electron donor colorant sprayed on a surface to which no electron donor has adhered. DETAILED DESCRIPTION OF THE INVENTION

[0011] 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 the surface where urine components are attached, the bleaching component reacts with the urine components, which are electron donors, reducing 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 consists of an electron-donating colorant and a solvent, is sprayed on top of it, 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 where urine components are attached can be colored and visualized. Liquid A can be sprayed before Liquid B, or they can be sprayed simultaneously.

[0012] Electron donors that can be visualized include proteins made up of amino acids, sweeteners containing glucose and glucose, and juices. The amino groups of amino acids and ether groups of glucose and glucose 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 bonding sites (δ-), such as C=C, C=N, CN (including peptide bonds), -NH2, -NH-, and -SH, are easily oxidized. For this reason, in addition to urine components, ,Ta It is also possible to visualize compounds such as proteins, amino acids, and sugars.

[0013] 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 %.

[0014] 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, either singly or in combination. The amount of the organic solvent added is preferably in the range of 60 to 99.99% by weight.

[0015] 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%.

[0016] In the present invention, an alkali metal silicate is added to one or both of Solution A and Solution B. Examples of alkali metal silicates include sodium metasilicate, sodium sesquisilicate, and sodium orthosilicate. The content of these is preferably 10 ppm to 20 wt%, and more preferably 100 ppm to 10 wt%.

[0017] 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.

[0018] 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. At the site of attachment of electron donors, such as urine components or protein components, the electron acceptor contained in liquid B is consumed by oxidizing the electron donor. Therefore, the electron donor colorant is not oxidized, and the site of attachment of the electron donor develops color. However, at non-attached sites, the electron acceptor contained in liquid B is not consumed, breaking the bonds in the dye molecular structure and preventing color development. In this way, only the site of attachment of the electron donor can be colored and visualized.

[0019] However, because the sprayed liquid contains substances such as charged surfactants and free substances, some of the broken dye bonds may steal electrons from these substances, causing re-coloring (color restoration) over time. In the present invention, alkali metal silicates such as sodium metasilicate, sodium sesquisilicate, and sodium orthosilicate are added to one or both of solutions A and B. These compounds coordinate with the broken dye bonds and prevent it from receiving electrons from the surfactants and free substances. As a result, the present invention does not suffer from color restoration as in the past, and surfaces to which the electron donor does not adhere remain colorless. Therefore, cleaning is simplified by concentrating on cleaning only the areas where the colored electron donor is attached. Examples and comparative examples are shown below. [Example]

[0020] Solution A was prepared with the composition shown in Table 1, and solution B was prepared with the composition shown in Table 2. The solvent for solution A was distilled water, the electron-donating colorant was an anthraquinone dye, and citric acid was added as a pH adjuster. Polyoxyethylene alkyl ether sulfate triethanolamine was also added as a surfactant. Solution A was the same for all of the examples and comparative examples.

[0021] The composition of Liquid B is as shown in Table 2, with tap water as the solvent and sodium hypochlorite as the electron acceptor. Smectite, a water-swellable silicate particle, was added as a thickener. Sodium metasilicate was added in Examples 1-3. Comparative Example 1 consisted only of a solvent, sodium hypochlorite, and smectite. Sodium hydroxide was added instead of sodium metasilicate in Comparative Example 2, and sodium bicarbonate was added in Comparative Example 3. Liquids A and B were sprayed sequentially onto a wall surface to which the target component had been attached, and evaluation was performed immediately after spraying to determine whether or not the attached area had discolored and whether or not the non-attached area had returned to its original color. The results are shown in Table 2. The target component was urine, except for Example 3, in which milk was used.

[0022] In each example, coloring of the applied area was confirmed, but no color reversal of the non-applied area was observed. The same was true for Example 3, in which milk was used as the target ingredient. In contrast, in the comparative example, coloring of the applied area was confirmed, but color reversal of the non-applied area was observed. The presence or absence of color reversal was visually observed 3 hours after spraying.
