Description
本発明は、カビ取り効果及び防カビ効果を兼ね備えた防カビ・カビ取り剤に関する。 The present invention relates to an antifungal and antifungal agent that has both an antifungal effect and an antifungal effect.
浴室・トイレ、キッチン等のタイル、目地、プラスチックに付着する汚れの中で、特にカビによって発生する汚れの除去には次亜塩素酸塩を主成分とする液体洗浄剤が一般的に使用されている。 Liquid stains mainly composed of hypochlorite are commonly used to remove stains caused by mold, especially in bathrooms, toilets, kitchens, and other tiles, joints, and plastic. Yes.
例えば、特許文献１には、次亜塩素酸塩と、苛性アルカリとを含有する水溶液中に、洗浄成分としてラウリルジメチルアミンオキシドを配合した液体洗浄剤が開示されている。また、特許文献２には、次亜塩素酸塩と、苛性アルカリとを含有する水溶液中に、デシルジメチルアミノキシド０．２〜３．０重量％配合することにより、ハンドスプレーでスプレーしたときの泡化性を向上させた液体洗浄剤組成物が開示されている。 For example, Patent Document 1 discloses a liquid detergent in which lauryl dimethylamine oxide is blended as a washing component in an aqueous solution containing hypochlorite and caustic. Moreover, in patent document 2, when spraying by hand spray by mix | blending 0.2-3.0 weight% of decyl dimethylaminooxide in the aqueous solution containing a hypochlorite and a caustic alkali. A liquid detergent composition with improved foamability is disclosed.
また、特許文献３には、次亜塩素酸アルカリ金属塩０．５〜５重量％、アルカリ金属水酸化物０．２〜０．５重量％、炭素鎖８〜１６のアルキル基を１つ以上含有するアミンオキシド型界面活性剤及び炭素鎖８〜６のアルキル基を１つ以上含有するカルボキシベタイン型界面活性剤から選ばれる両性界面活性剤０．０５〜１重量％、並びにクメンスルホン酸、キシレンスルホン酸、トルエンスルホン酸及びこれらのアルカリ金属塩から選ばれる１種以上０．１〜３重量％を含有する液体漂白洗浄剤組成物が開示されている。 Further, Patent Document 3 includes one or more alkyl groups having 0.5 to 5% by weight of alkali metal hypochlorite, 0.2 to 0.5% by weight of alkali metal hydroxide, and 8 to 16 carbon chains. 0.05 to 1% by weight of an amphoteric surfactant selected from an amine oxide type surfactant and a carboxybetaine type surfactant containing at least one alkyl group having 8 to 6 carbon chains, and cumene sulfonic acid, xylene A liquid bleaching detergent composition containing 0.1 to 3% by weight of at least one selected from sulfonic acid, toluenesulfonic acid and alkali metal salts thereof is disclosed.
一方、特許文献４には、炭素鎖３〜２２のアルキル基を含有するアミンオキシドを防カビ成分として用いるカビの防除方法、並びに液状カビ防除組成物が開示されている。 On the other hand, Patent Document 4 discloses a mold control method and a liquid mold control composition using an amine oxide containing an alkyl group having 3 to 22 carbon chains as a mold control component.
上記のような液体洗浄剤においては、使用した際の洗浄効果、カビ取り効果に加えて、持続的な防カビ効果を有することが望ましい。しかしながら、次亜塩素酸はあらゆる有機化合物に対して反応性を示し、保存中に徐々に分解するため、次亜塩素酸塩を主成分とする液体洗浄剤に有機抗菌剤、カビ取り剤を配合することは困難であった。そのため、上記特許文献１〜３に記載の液体洗浄剤では、使用時の洗浄性（漂白性）、泡立ち性、および液状組成物の保存安定性（次亜塩素酸の残存率）の試験結果については記載されているものの、持続的な防カビ効果については何ら考慮されていなかった。 In the liquid cleaning agent as described above, it is desirable to have a continuous antifungal effect in addition to a cleaning effect and a mold removing effect when used. However, hypochlorous acid is reactive with all organic compounds and gradually decomposes during storage. Therefore, organic antibacterial agents and fungicides are added to liquid detergents based on hypochlorite. It was difficult to do. Therefore, in the liquid detergents described in Patent Documents 1 to 3 above, the test results of the washability (bleachability), foamability, and storage stability of the liquid composition (remaining rate of hypochlorous acid) at the time of use. However, no consideration was given to the sustained fungicidal effect.
また、特許文献４には、炭素鎖１２のアルキル基を含有するアミンオキシドであるラウリルジメチルアミンオキシドを配合した液状組成物の防カビ試験結果が実施例として記載されているものの、アミンオキシドの種類と防カビ効果との関係については何ら記載されていなかった。また、防カビ効果についても、黒麹かびの胞子をラウリルジメチルアミンオキシドの水溶液と接触させた後の生育状況を観察するという、いわゆる「in vitro」での試験結果しか記載されておらず、実際の使用環境下での防カビ効果は定かではなかった。さらに、次亜塩素酸塩を含む液状組成物に配合した場合の保存安定性や泡化性についても検討されておらず、カビ防除組成物として十分とはいえなかった。 In addition, Patent Document 4 describes, as an example, the antifungal test results of a liquid composition containing lauryldimethylamine oxide, which is an amine oxide containing an alkyl group of carbon chain 12, but the type of amine oxide There was no description about the relationship between the antifungal effect and the fungicidal effect. In addition, as for the fungicidal effect, only the so-called “in vitro” test result of observing the growth situation after contacting black mold fungus spores with an aqueous solution of lauryldimethylamine oxide is described. The fungicidal effect under the usage environment was not clear. Furthermore, the storage stability and foaming properties when blended with a liquid composition containing hypochlorite have not been examined, and it was not sufficient as a mold control composition.
本発明は、上記問題点に鑑み、優れたカビ取り効果、防カビ効果を兼ね備えるとともに、カビ取り成分である次亜塩素酸塩の安定性にも優れた防カビ・カビ取り剤を提供することを目的とする。 In view of the above problems, the present invention provides an antifungal and antifungal agent that has both an excellent antifungal effect and an antifungal effect, and is also excellent in the stability of hypochlorite that is an antifungal component. With the goal.

以下、本発明の防カビ・カビ取り剤について詳細に説明する。本発明の防カビ・カビ取り剤は、次亜塩素酸塩、苛性アルカリ、ヒドロトロープ剤を含有する水溶液に、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドを１重量％以上８重量％以下の割合で配合したことを特徴とする。 Hereinafter, the fungicide and mold remover of the present invention will be described in detail. The fungicide and mold remover of the present invention is an aqueous solution containing hypochlorite, caustic alkali, and hydrotrope, 1% by weight or more of alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms. It is characterized by blending at a ratio of 8% by weight or less.
本発明の防カビ・カビ取り剤に用いられる次亜塩素酸塩としては、ナトリウム塩やカリウム塩等の次亜塩素酸アルカリ金属塩が使用できるが、工業的に多量に生産されていて安価な次亜塩素酸ナトリウムの使用が好ましい。これらの次亜塩素酸塩は、有効性と安定性の観点から、組成物中に０．５〜６重量％、好ましくは２〜４重量％配合することが望ましい。 As hypochlorite used in the mold-proofing agent of the present invention, hypochlorite alkali metal salts such as sodium salt and potassium salt can be used, but industrially produced in large quantities and inexpensive. The use of sodium hypochlorite is preferred. These hypochlorites are desirably blended in the composition in an amount of 0.5 to 6% by weight, preferably 2 to 4% by weight, from the viewpoint of effectiveness and stability.
苛性アルカリは、一般的に次亜塩素酸塩を安定化するために使用される。本発明の防カビ・カビ取り剤に用いられる苛性アルカリとしては、水酸化ナトリウムや水酸化カリウムが挙げられる。これらの苛性アルカリは、防カビ・カビ取り剤中に０．５〜４重量％配合される。なお、苛性アルカリの配合量が多くなると使用時の安全性が懸念されるため、洗浄剤・漂白剤等安全対策協議会（安対協）の自主基準でもある１重量％以下とすることが好ましい。 Caustic is generally used to stabilize hypochlorite. Sodium hydroxide and potassium hydroxide are mentioned as caustic alkali used for the fungicide and mold remover of the present invention. These caustic alkalis are blended in an amount of 0.5 to 4% by weight in an antifungal / mold removing agent. In addition, since the safety | security at the time of use may be anxious if the compounding quantity of a caustic alkali increases, it is preferable to set it as 1 weight% or less which is also a voluntary standard of a safety measures meeting, such as a cleaning agent and a bleaching agent. .
アルキルジメチルアミンオキシドは、一般的に汚れを除去する界面活性剤として使用されるが、本発明において、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドが高い防カビ効果を兼備することが確認された。本発明の防カビ・カビ取り剤に用いられる、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドとしては、炭素数が１４のミリスチル基を有するミリスチルジメチルアミンオキシド、炭素数が１６のパルミチル基を有するパルミチルジメチルアミンオキシド、炭素数が１８のステアリル基を有するステアリルジメチルアミンオキシド等が挙げられる。 Alkyldimethylamine oxide is generally used as a surfactant for removing dirt. In the present invention, alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms has a high antifungal effect. It was confirmed. Examples of the alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms, which is used in the mold-proofing / mold-removing agent of the present invention, include myristyldimethylamine oxide having a myristyl group having 14 carbon atoms, and having 16 carbon atoms. And palmityl dimethylamine oxide having a palmityl group, stearyl dimethylamine oxide having a stearyl group having 18 carbon atoms, and the like.
炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドの配合量が１重量％未満の場合、十分な防カビ効果が得られない。一方、配合量が８重量％を超える場合、次亜塩素酸塩の安定性に悪影響を及ぼす。また、防カビ・カビ取り剤の粘度が上昇するため、円滑なスプレーが困難となる。従って、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドの配合量は１重量％以上８重量％以下とする必要がある。 When the blending amount of the alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms is less than 1% by weight, a sufficient antifungal effect cannot be obtained. On the other hand, if the blending amount exceeds 8% by weight, the stability of hypochlorite is adversely affected. In addition, since the viscosity of the fungicide / mold remover increases, smooth spraying becomes difficult. Therefore, the blending amount of the alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms needs to be 1 wt% or more and 8 wt% or less.
ところで、次亜塩素酸塩を含有する洗浄剤は、簡便性の点からハンドスプレー等を利用してスプレーするような使用形態が好ましいが、次亜塩素酸塩は刺激性があるため、スプレー時に空気中に飛散したミストを使用者が吸い込んで身体に悪影響を及ぼすという問題点がある。そのため、スプレーしたときに泡化するようにし、空気中に飛散するミストを減少させることが好ましい。また、泡化することにより、壁面にスプレーしたときの塗布領域を容易に視認することができる。 By the way, the cleaning agent containing hypochlorite is preferably used in a form of spraying using hand spray or the like from the viewpoint of simplicity, but hypochlorite is irritating, so when spraying There is a problem that the user inhales mist scattered in the air and adversely affects the body. Therefore, it is preferable to make it foam when sprayed and to reduce mist scattered in the air. Moreover, by foaming, the application area | region when spraying on a wall surface can be visually recognized easily.
しかし、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドは、泡立ち効果が低い。そこで、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドに加えて、泡化性に優れた炭素数が１０以下の直鎖アルキル基を有するアルキルジメチルアミンオキシドを添加することが好ましい。炭素数が１０以下のアルキル基を有するアルキルジメチルアミンオキシドとしては、炭素数が１０のデシル基を有するデシルジメチルアミンオキシド、炭素数が８のオクチル基を有するオクチルジメチルアミンオキシド等が挙げられる。 However, alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms has a low foaming effect. Therefore, in addition to the alkyldimethylamine oxide having a linear alkyl group having 14 or more carbon atoms, it is preferable to add an alkyldimethylamine oxide having a linear alkyl group having 10 or less carbon atoms with excellent foaming properties. . Examples of the alkyldimethylamine oxide having an alkyl group having 10 or less carbon atoms include decyldimethylamine oxide having a decyl group having 10 carbon atoms and octyldimethylamine oxide having an octyl group having 8 carbon atoms.
炭素数が１０以下の直鎖アルキル基を有するアルキルジメチルアミンオキシドの配合量が０．０１重量％未満の場合、ハンドスプレー等でスプレーしたとき十分な泡立ち効果が得られない。一方、配合量が１重量％を超える場合、次亜塩素酸塩の安定性に悪影響を与える可能性がある。従って、本発明の防カビ・カビ取り剤中における炭素数が１０以下の直鎖アルキル基を有するアルキルジメチルアミンオキシドの配合量は、泡立ち性と次亜塩素酸塩の安定性に対する影響等の観点から、０．０１重量％以上１重量％以下であることが好ましい。 When the blending amount of the alkyldimethylamine oxide having a linear alkyl group having 10 or less carbon atoms is less than 0.01% by weight, a sufficient foaming effect cannot be obtained when sprayed by hand spray or the like. On the other hand, if the blending amount exceeds 1% by weight, the stability of hypochlorite may be adversely affected. Therefore, the compounding amount of the alkyldimethylamine oxide having a straight-chain alkyl group having 10 or less carbon atoms in the fungicide and mold remover of the present invention is the viewpoint of the influence on foaming property and stability of hypochlorite. From 0.01% by weight to 1% by weight is preferable.
ヒドロトロープ剤は、一般的に界面活性剤の水に対する溶解度を高めることにより、温度変化による粘性の変化や界面活性剤の析出を防止するものであるが、本発明では、苛性アルカリ、及びアルキルジメチルアミンオキシドと併用することで、次亜塩素酸塩の安定化剤として作用することが見いだされた。本発明の防カビ・カビ取り剤に用いられるヒドロトロープ剤は、下記の化学式（１）で表される化合物が好ましい。
式（１）中、Ｒ１はメチル基又はイソプロピル基、Ｒ２はメチル基又は水素、Ｍはアルカリ金属又はアンモニウムを表す。ヒドロトロープ剤の具体例としては、ｍ−キシレンスルホン酸ナトリウム（Ｒ１、Ｒ２；メチル基、Ｍ；Ｎａ）、ｐ−トルエンスルホン酸ナトリウム（Ｒ１；メチル基、Ｒ２；水素、Ｍ；Ｎａ）、ｐ−クメンスルホン酸ナトリウム（Ｒ１；イソプロピル基、Ｒ２；水素、Ｍ；Ｎａ）が挙げられる。特に、化学製品として汎用されており入手が容易なｍ−キシレンスルホン酸ナトリウムが好ましい。 In formula (1), R1 represents a methyl group or isopropyl group, R2 represents a methyl group or hydrogen, and M represents an alkali metal or ammonium. Specific examples of the hydrotrope include sodium m-xylenesulfonate (R1, R2; methyl group, M; Na), sodium p-toluenesulfonate (R1; methyl group, R2; hydrogen, M; Na), p -Sodium cumene sulfonate (R1; isopropyl group, R2; hydrogen, M; Na). In particular, sodium m-xylene sulfonate, which is widely used as a chemical product and is easily available, is preferable.
また、化学式（１）で表されるヒドロトロープ剤は、単独で配合した場合は次亜塩素酸塩の安定性を低下させる傾向を示すが、炭素数が１４以上の直鎖アルキル基を有するアルキルジメチルアミンオキシドと併用することで、後述するように次亜塩素酸塩の安定性を向上させる作用を示すことが確認された。 In addition, the hydrotrope represented by the chemical formula (1) tends to lower the stability of hypochlorite when it is added alone, but the alkyl having a linear alkyl group having 14 or more carbon atoms. It was confirmed that when used in combination with dimethylamine oxide, the effect of improving the stability of hypochlorite is exhibited as described later.
ヒドロトロープ剤の配合量が０．１重量％未満の場合、次亜塩素酸塩の十分な安定化効果が得られない。一方、配合量が１０重量％を超える場合、次亜塩素酸塩の安定性に悪影響を及ぼす。従って、ヒドロトロープ剤の配合量は０．０１重量％以上１０重量％以下であることが好ましい。 When the blending amount of the hydrotrope is less than 0.1% by weight, a sufficient stabilizing effect of hypochlorite cannot be obtained. On the other hand, if the blending amount exceeds 10% by weight, the stability of hypochlorite is adversely affected. Therefore, the blending amount of the hydrotrope is preferably 0.01% by weight or more and 10% by weight or less.
本発明の防カビ・カビ取り剤に用いられる他のヒドロトロープ剤としては、脂肪族、芳香族ならびにアルキル環状化合物のカルボン酸塩等が挙げられ、具体的には、安息香酸ナトリウムやカリウム、アンモニウム塩が挙げられる。 Examples of other hydrotropes used in the fungicide and mold remover of the present invention include aliphatic, aromatic and alkyl cyclic compound carboxylates and the like. Specifically, sodium benzoate, potassium, ammonium, and the like. Salt.
本発明の液体洗浄剤組成物は、また、次亜塩素酸塩水溶液中で使用可能な他の界面活性剤やキレート剤も配合することができる。次亜塩素酸塩水溶液中で使用可能な他の界面活性剤としては、既に公知のアルキルジフェニルエーテルジスルホネート、アルキルフェノールポリオキシエチレンエーテルサルフェート、アルキルフェノールポリオキシエチレンエーテルサルフェートモノスルホネート、脂肪酸アルカリ金属塩等が挙げられ、これらの界面活性剤を１種または２種以上を併用して使用できる。 The liquid detergent composition of the present invention can also contain other surfactants and chelating agents that can be used in hypochlorite aqueous solutions. Examples of other surfactants that can be used in hypochlorite aqueous solutions include already known alkyl diphenyl ether disulfonates, alkylphenol polyoxyethylene ether sulfates, alkylphenol polyoxyethylene ether sulfate monosulfonates, and fatty acid alkali metal salts. These surfactants can be used alone or in combination of two or more.
次亜塩素酸塩水溶液中で使用可能なキレート剤としては、１−ヒドロキシエチリデン−１，１−ジホスホン酸塩、２−ホスホノブタン−１，２，４−トリカルボン酸塩が挙げられる。これらのキレート剤は原料等から由来するＦｅ，Ｃｕ，Ｎｉ等の重金属イオンによる次亜塩素酸塩の分解を抑止する。また、Ｃａ，Ｍｇイオン等に起因する汚れに対して有効な洗浄補助成分として作用する。 Examples of the chelating agent that can be used in the hypochlorite aqueous solution include 1-hydroxyethylidene-1,1-diphosphonate and 2-phosphonobutane-1,2,4-tricarboxylate. These chelating agents inhibit the decomposition of hypochlorite by heavy metal ions such as Fe, Cu and Ni derived from raw materials. Also, it acts as an effective cleaning auxiliary component against dirt caused by Ca, Mg ions and the like.
更に、本発明の液体洗浄剤組成物には、その他の成分として、必要に応じて香料や紫外線吸収剤、防腐剤等を本発明の効果を妨げない範囲で配合することができる。 Furthermore, in the liquid cleaning composition of the present invention, as other components, a fragrance, an ultraviolet absorber, a preservative and the like can be blended as long as they do not interfere with the effects of the present invention.

[Confirmation test of antifungal effect (quasi-practical test)]
A 10 cm × 10 cm semi-porcelain tile (MLP-100, manufactured by INAX) was immersed in tap water for 1 hour, then drained for 15 minutes, and the present invention 1-9, Comparative Examples 1 to 3 from a distance of 30 cm on the unglazed surface on the back side. The test solution of No. 4 and a commercially available mold remover were sprayed three times with a hand spray (T-95 trigger, manufactured by Canyon), spread with a sponge, allowed to stand for 5 minutes, and then rinsed with running water for 10 seconds. In addition, as a comparative control example, a test liquid and a commercially available fungicide that were not applied (no treatment) were prepared.
本発明１〜９、比較例１〜４の試験液、または市販のカビ取り剤を処理したタイル、並びに無処理タイルを常温で一晩乾燥した後、浴室のシャワー等がよくかかる場所に素焼き面を表向きにして設置した。２週間放置後、カビの生育状況を目視および顕微鏡で観察した。評価基準としては、目視により明らかにカビの生育が確認される場合を＋＋、目視により少しカビの生育が確認される場合を＋、目視ではカビの生育が確認されないが、顕微鏡で１、２箇所カビの生育が確認できる場合をδ＋、カビの生育が全く確認されない場合を−とした。次亜塩素酸ナトリウムの安定性、防カビ効果の試験結果を試験液の配合と併せて表１、表２に示す After drying the tiles treated with the test liquids of the present invention 1 to 9, comparative examples 1 to 4, or a commercially available mold remover, and the untreated tile at room temperature overnight, the unglazed surface is often exposed to a bathroom shower or the like. Was placed face up. After standing for 2 weeks, mold growth was observed visually and with a microscope. The evaluation criteria are ++ when mold growth is clearly confirmed visually, + when mold growth is slightly confirmed visually, and mold growth is not visually confirmed, but 1 or 2 places under a microscope The case where mold growth could be confirmed was designated as δ +, and the case where mold growth was not confirmed at all. Tables 1 and 2 show the test results of the stability and antifungal effect of sodium hypochlorite together with the composition of the test solution.
表１から明らかなように、１重量％以上のミリスチルジメチルアミンオキシド（Ｃ１４ＡＯ）を配合した本発明１〜８の試験液、及び、０．５重量％のミリスチルジメチルアミンオキシドと４重量％のヤシ油ジメチルアミンオキシドを配合した本発明９の試験液（ミリスチルジメチルアミンオキシドの総量として１．１〜１．２重量％）では、２週間後においてもほとんどカビの発生は認められなかった。特に、ミリスチルジメチルアミンオキシドを２重量％以上配合した本発明２、３、５〜７の試験液では、２週間後に全くカビの生育はなく、極めて高い防カビ効果が確認された。 As is clear from Table 1, the test solutions of the present invention 1 to 8 containing 1% by weight or more of myristyl dimethylamine oxide (C14AO), 0.5% by weight of myristyl dimethylamine oxide and 4% by weight of palm In the test solution of the present invention 9 containing oil dimethylamine oxide (1.1 to 1.2% by weight as the total amount of myristyl dimethylamine oxide), almost no mold was observed even after 2 weeks. In particular, in the test solutions of the present inventions 2, 3, and 5 to 7 containing 2% by weight or more of myristyldimethylamine oxide, no mold growth occurred after 2 weeks, and an extremely high antifungal effect was confirmed.
一方、０．５重量％のミリスチルジメチルアミンオキシド（Ｃ１４ＡＯ）を配合した比較例１の試験液、及び、ミリスチルジメチルアミンオキシド（Ｃ１４ＡＯ）に代えて、２重量％のデシルジメチルアミンオキシド（Ｃ１０ＡＯ）またはラウリルジメチルアミンオキシド（Ｃ１２ＡＯ）を配合した比較例２，３の試験液では、２週間後に明らかなカビの生育が認められた。 On the other hand, instead of the test solution of Comparative Example 1 containing 0.5% by weight of myristyldimethylamine oxide (C14AO) and myristyldimethylamine oxide (C14AO), 2% by weight of decyldimethylamine oxide (C10AO) or In the test solutions of Comparative Examples 2 and 3 containing lauryldimethylamine oxide (C12AO), obvious mold growth was observed after 2 weeks.
また、水酸化ナトリウムを０．２〜０．９重量％、ヒドロトロープ剤としてｍ−キシレンスルホン酸ナトリウムを１．５〜５重量％配合した本発明１〜９の試験液では、５０℃で１週間保存後の次亜塩素酸ナトリウム濃度（残存率）が、いずれも市販のカビ取り剤と同等以上である８５％以上であり、防カビ効果と次亜塩素酸の安定性を両立できることが確認された。これに対し、水酸化ナトリウムを０．５重量％配合し、ｍ−キシレンスルホン酸ナトリウムを配合しなかった比較例４の試験液では、５０℃で１週間保存後の次亜塩素酸ナトリウム濃度（残存率）が８０％以下となり、安定性の面で劣る結果となった。 Moreover, in the test liquid of this invention 1-9 which mix | blended sodium hydroxide m-xylenesulfonate 1.5 to 5weight% as a hydrotrope agent 0.2 to 0.9weight%, it is 1 at 50 degreeC. The sodium hypochlorite concentration (residual rate) after weekly storage is 85% or more, which is equal to or higher than that of commercially available mold removers, and it is confirmed that both the antifungal effect and the stability of hypochlorous acid can be achieved. It was done. On the other hand, in the test solution of Comparative Example 4 containing 0.5% by weight of sodium hydroxide and not containing sodium m-xylene sulfonate, the concentration of sodium hypochlorite after storage at 50 ° C. for 1 week ( Residual rate) was 80% or less, which was inferior in terms of stability.
一般に、次亜塩素酸の安定化剤としては水酸化ナトリウム等の苛性アルカリを用いるが、安全性を考慮すると、苛性アルカリの配合量は１重量％以下であることが好ましい。本発明１〜９のように、ヒドロトロープ剤としてｍ−キシレンスルホン酸ナトリウムを１．５重量％以上配合することで、苛性アルカリの配合量を１重量％以下に抑えることができる。また、ｍ−キシレンスルホン酸ナトリウムを単独で配合した場合は次亜塩素酸の安定性を低下させる傾向にあるが、本実施例のようにミリスチルジメチルアミンオキシドと併用することで、次亜塩素酸の安定性を向上させる結果が得られた。この結果より、ｍ−キシレンスルホン酸ナトリウムは、ミリスチルジメチルアミンオキシドとの相乗効果によって次亜塩素酸の安定性を向上させる作用があるものと推測される。 In general, a caustic alkali such as sodium hydroxide is used as a stabilizer for hypochlorous acid. However, in consideration of safety, the blending amount of the caustic alkali is preferably 1% by weight or less. As in the present inventions 1 to 9, by adding 1.5% by weight or more of sodium m-xylene sulfonate as a hydrotrope, the amount of caustic alkali can be suppressed to 1% by weight or less. In addition, when sodium m-xylene sulfonate is blended alone, it tends to lower the stability of hypochlorous acid, but hypochlorite can be used in combination with myristyldimethylamine oxide as in this example. The result of improving the stability of was obtained. From this result, it is surmised that sodium m-xylene sulfonate has an action of improving the stability of hypochlorous acid by a synergistic effect with myristyldimethylamine oxide.
さらに、ミリスチルジメチルアミンオキシドに加えてデシルジメチルアミンオキシド（Ｃ１０ＡＯ）を配合した本発明２、３の試験液では、防カビ効果に加えて泡化性にも優れたものとなった。従って、スプレーしたときに十分に泡化し、空気中に飛散する次亜塩素酸のミストを減少させることができる。また、泡化することにより、壁面にスプレーしたときの塗布領域も容易に視認することができる。 Furthermore, in the test liquids of the present inventions 2 and 3 in which decyldimethylamine oxide (C10AO) was blended in addition to myristyldimethylamine oxide, the foaming property was excellent in addition to the antifungal effect. Accordingly, hypochlorous acid mist that is sufficiently foamed and sprayed into the air when sprayed can be reduced. Moreover, the application area | region when spraying on a wall surface can also be visually recognized easily by foaming.
本発明は、カビ取り効果及び防カビ効果を兼ね備えた防カビ・カビ取り剤に利用可能である。本発明の利用により、次亜塩素酸塩による即効的なカビ取り効果と、ミリスチルジメチルアミンオキシドによる持続的な防カビ効果とを兼ね備えるとともに、次亜塩素酸塩の安定性にも優れた防カビ・カビ取り剤を提供することができる。 INDUSTRIAL APPLICABILITY The present invention can be used for an antifungal and antifungal agent having both an antifungal effect and an antifungal effect. By utilizing the present invention, it has both an immediate mold removal effect by hypochlorite and a sustained mold prevention effect by myristyldimethylamine oxide, and also has an excellent anti-hypochlorite stability.・ A mold remover can be provided.
