Description

【0001】
【産業上の利用分野】
本発明は刺激臭がなく、しかもカビ取り洗浄力の優れた過酸化物系カビ取り剤組成物に関する。本発明のカビ取り剤組成物は、住居の壁や家具等に発生したカビの漂白に利用される。
【0002】
【従来の技術】
住居の壁や家具についたカビを漂白するために、従来より次亜塩素酸ソーダを主成分とする塩素系漂白剤が使用されている。しかし、塩素系漂白剤は漂白力は優れているものの、分子状塩素による特有の臭気が発生して使用者に不快感を与え、また、使用方法によっては塩素ガスによる中毒の危険があるという欠点がある。さらに、塩素系漂白剤は有機塩素系化合物を副生するおそれがあり、環境保護の観点からも塩素系化合物を使用しない漂白剤への切り替えが望まれている。
【0003】
住居の家具や壁、特に台所流し台、浴室の壁や天井やタイル目地についた汚れを除去するためには、かかる汚れが主にカビで構成されているために、カビに対する強い除去ないし漂白作用が要求される。しかしながら、カビは一般の漂白剤に対し強い抵抗性を示し、繊維などの漂白に比べ、カビを完全に漂白することは極めて困難である。すなわち、過酸化水素、無機過酸化物、有機過酸化物等の過酸化物系漂白剤は単独ではカビに対する漂白力が弱く、カビを完全に漂白することは困難である。
【0004】
過酸化物系漂白剤による漂白作用の向上については、種々提案されている。特開昭61−42600号公報には、グルコースペンタアセテート、テトラアセチルエチレンジアミン、テトラアセチルグリコールウリル、シアナミドなどが活性化剤として酸素系漂白剤と併用し得ることが開示されている。しかし、開示された活性化剤を含む組成物はカビに対してはいずれも漂白力が十分でなかったり、また、しばしば過酸化水素と反応して刺激臭のある化合物を副生して実用に適しないという問題を有する。
【0005】
また、特開昭52−110287号公報には過酸化物とシアナミド及び/又は金属シアナミドからなる繊維用の漂白剤組成物が開示されているが、カビに対しては漂白力が十分でない。米国特許3756774号明細書には過酸化物と有機シアニドを含有するpH4〜7の繊維用の漂白剤組成物が開示されているが、カビに対しては漂白力が十分でない。特開昭62−1790号公報には過酸化物とシリコンオイル又は/及びその乳化物とを含有するカビ取り剤組成物が開示されているが、カビに対する漂白力は十分でない。また、特開昭62−149800号公報には過酸化物の活性化剤としてシアン酸アルカリ金属塩が開示されているが、カビの漂白については記載が無い。
【0006】
【発明が解決しようとする課題】

が出来る。
【0017】
本発明のカビ取り剤組成物は、通常、水に(A)過酸化水素又は過酸化水素と付加物を形成している化合物、および、(B)シアン酸のアルカリ金属塩又はシアン酸のアンモニウム塩を溶解して製造される。本発明のカビ取り剤組成物は、均一な水溶液であってもスラリー状の水溶液であってもよい。本発明のカビ取り剤組成物の溶媒である水の含有量は、カビ取り剤組成物全体の中で40〜99重量%、好ましくは50〜98重量%、より好ましくは60〜97重量%の範囲から選ばれる。
【0018】
本発明のカビ取り剤組成物には、更に界面活性剤を添加することが好ましい。界面活性剤としては、ポリオキシエチレンアルキルエーテル、ポリオキシエチレン脂肪酸エステル、アミンオキサイド等の非イオン界面活性剤、石鹸、アルキル硫酸塩、アルキルベンゼンスルホン酸塩等の陰イオン界面活性剤等が例示される。界面活性剤の添加量はカビ取り剤組成物全体の中で0.1〜5重量%となる量が好ましい。界面活性剤の添加により、カビに対するカビ取り剤組成物の浸透を助け、カビの漂白および洗浄・除去効果を高めることができる。
【0019】
本発明のカビ取り剤組成物は溶液状態又はスラリー状態として使用され、カビの付着した住居の壁や家具の表面にスプレー等で散布するか又は刷毛等で塗布することにより、効果的にカビを漂白することができる。

[Industrial application fields]
The present invention relates to a peroxide-type mold remover composition that has no irritating odor and has excellent mold-removing ability. The mold removing composition of the present invention is used for bleaching mold generated on a wall or furniture of a house.
[0002]
[Prior art]
Conventionally, chlorine bleach containing sodium hypochlorite as a main component has been used to bleach molds on the walls and furniture of houses. However, although the bleaching power of chlorine-based bleaching agents is excellent, there is a disadvantage that a specific odor due to molecular chlorine is generated, causing discomfort to the user, and depending on the method of use, there is a risk of poisoning due to chlorine gas. There is. Further, there is a possibility that the chlorine bleaching agent may produce an organic chlorine compound, and switching to a bleaching agent that does not use the chlorine compound is desired from the viewpoint of environmental protection.
[0003]
In order to remove stains on residential furniture and walls, especially kitchen sinks, bathroom walls, ceilings and tile joints, such stains are mainly composed of mold, so strong removal or bleaching action against mold is required. Required. However, mold exhibits strong resistance to general bleaching agents, and it is extremely difficult to completely bleach mold compared to bleaching fibers and the like. That is, peroxide bleaching agents such as hydrogen peroxide, inorganic peroxides and organic peroxides alone have a weak bleaching ability against mold, and it is difficult to completely bleach mold.
[0004]
Various proposals have been made to improve the bleaching action by the peroxide bleaching agent. JP-A-61-42600 discloses that glucose pentaacetate, tetraacetylethylenediamine, tetraacetylglycoluril, cyanamide and the like can be used in combination with an oxygen bleach as an activator. However, none of the compositions containing the disclosed activator has sufficient bleaching power against mold, and often reacts with hydrogen peroxide to produce a compound with an irritating odor as a by-product. It has the problem of not being suitable.
[0005]
Japanese Patent Application Laid-Open No. 52-110287 discloses a bleaching composition for fibers comprising a peroxide and cyanamide and / or metal cyanamide, but it does not have sufficient bleaching power against mold. U.S. Pat. No. 3,756,774 discloses a bleaching composition for fibers having a pH of 4 to 7 containing a peroxide and an organic cyanide, but it does not have sufficient bleaching power against mold. Japanese Patent Application Laid-Open No. 62-1790 discloses a mold removing composition containing a peroxide and silicon oil or / and an emulsion thereof, but the bleaching power against mold is not sufficient. Japanese Laid-Open Patent Publication No. 62-149800 discloses alkali metal cyanate as a peroxide activator, but does not describe mold bleaching.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to provide a mold remover composition having no irritating odor and having excellent bleaching power against mold on a wall or furniture of a house, particularly a kitchen sink, bathroom wall, ceiling or tile joint, and such mold. Is to provide a bleaching method.
[0007]
[Means for Solving the Problems]
As a result of diligent research, the present inventors have found that a composition of cyanate and hydrogen peroxide exhibits a markedly high bleaching power against mold in a specific pH range and has no irritating odor. Completed the invention.
[0008]
The component (A) of the present invention is hydrogen peroxide or a peroxide that generates hydrogen peroxide in an aqueous solution. In particular, an aqueous hydrogen peroxide solution can be suitably used. The compounding amount of the component (A) in the mold remover composition of the present invention is generally 0.5 to 60% by weight, preferably 0.5 to 30% by weight, more preferably in terms of hydrogen peroxide to be produced. Is 0.5 to 10% by weight. From a practical viewpoint, 1 to 6% by weight is most preferable.
[0009]
Also, using a compound that forms an adduct with hydrogen peroxide as a peroxide,
Hydrogen peroxide may be generated in an aqueous solution. Examples of the compound forming an adduct with hydrogen peroxide include sodium carbonate hydrogen peroxide adduct, sodium perborate monohydrate and perboric acid in which sodium carbonate and hydrogen peroxide are added at a molar ratio of 2: 3. Soda tetrahydrate is exemplified. In the case of using a compound that forms an adduct with hydrogen peroxide, an amount of hydrogen peroxide generated by dissociation of the adduct in an aqueous solution is included in the above range is used.
[0010]
Next, examples of the alkali metal salt of cyanic acid and the ammonium salt of cyanic acid that are component (B) include potassium cyanate, sodium cyanate, and ammonium cyanate, and one or more of them are used. The blending amount of the component (B) in the mold removal composition of the present invention is 0.2 to 30% by weight, preferably 0.5 to 10% by weight, more preferably 0.5 to 5% by weight. . A commercially available solid cyanate can be used.
[0011]
The amount of the peroxide which is the component (A) in the fungicide composition is generally 0.5 to 60% by weight, preferably 0.5 to 30% by weight, more preferably 0.5 to 10%. % By weight. For practical use, 1 to 6% by weight is most preferable. (B) The compounding quantity of the cyanate which is a component is 0.2-30 weight%, Preferably it is 0.5-10 weight%, More preferably, it is 0.5-5 weight%. When the component (A) or the component (B) is less than this range, the bleaching effect is low, and when the component (A) or the component (B) is more than this range, it is difficult to handle as a mold removing composition.
[0012]
The pH of the fungicide composition of the present invention is important for obtaining high bleaching power, and is usually 7 to 13, preferably 8 to 13, and more preferably 9.0 to 12.4.
[0013]
If the pH is lower than this range, the bleaching action effect is low, and if it is higher than this range, the peroxide becomes unstable, making it difficult to handle as a mold removal composition.
[0014]
In the present invention, it is preferable to use an alkali metal hydroxide or an alkali metal silicate in order to adjust the pH of the mold removal composition to the above range. Examples of the alkali metal hydroxide or alkali metal silicate include alkali metal hydroxides such as lithium hydroxide, sodium hydroxide and potassium hydroxide, and alkali metal silicates such as sodium silicate and potassium silicate. it can. Among them, the use of alkali metal silicates such as sodium silicate and potassium silicate is preferable because the bleaching power is remarkably improved.
[0015]
The blending amount of the alkali metal hydroxide or the alkali metal silicate is selected from the range of 0.01 to 10% by weight, and the amount is used so that the pH of the mold removing composition is included in the above range.
[0016]
In addition, when using sodium carbonate hydrogen peroxide adduct or sodium perborate as a hydrogen peroxide generator, the aqueous solution of these adducts is alkaline by itself, so alkali metal hydroxide or alkali metal The amount of silicate used can be reduced.
[0017]
The mold remover composition of the present invention usually comprises (A) hydrogen peroxide or a compound forming an adduct with hydrogen peroxide in water, and (B) an alkali metal salt of cyanic acid or ammonium cyanate. Manufactured by dissolving salt. The mold remover composition of the present invention may be a uniform aqueous solution or a slurry aqueous solution. The content of water which is a solvent of the mold removing composition of the present invention is 40 to 99% by weight, preferably 50 to 98% by weight, more preferably 60 to 97% by weight in the whole mold removing composition. Selected from a range.
[0018]
It is preferable to further add a surfactant to the mold removing composition of the present invention. Examples of the surfactant include nonionic surfactants such as polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters and amine oxides, and anionic surfactants such as soaps, alkyl sulfates, and alkylbenzene sulfonates. . The amount of the surfactant added is preferably 0.1 to 5% by weight in the whole mold removal composition. By adding the surfactant, it is possible to help the fungicide composition to penetrate into the mold, and to increase the bleaching and cleaning / removal effect of the mold.
[0019]
The mold remover composition of the present invention is used as a solution state or a slurry state, and it is effectively spread by spraying or applying it to the surface of a residential wall or furniture to which mold has adhered by using a brush or the like. Can be bleached.
[0020]
