Description
本発明は、液体漂白剤組成物に関する。 The present invention relates to a liquid bleach composition.
浴室やトイレ、シンクに発生する細菌やカビに由来する黒ずみ汚れを除去するために、次亜塩素酸塩を配合した塩素系の漂白洗浄剤が用いられている。これらのカビは床や排水口など、水平に設置された部材だけではなく、浴室や浴槽の壁、窓枠など、垂直に設置された部材にも発生する。この様な垂直面に発生したカビを除去する方法として、スプレー時の起泡性を向上させたり、溶液粘度を高めたりするなど、対象物への付着時間を長くすることによって除去性能を向上させる方法が知られている。例えば、特許文献１には次亜塩素酸塩を含有する液体洗浄剤に、オクチルジメチルアミンオキサイドやラウリルジメチルアミンオキサイド等の特定２種のアミンオキサイドを併用することによって、汚れ面への付着性、滞留性を向上した液体洗浄剤組成物が開示されている。 Chlorine bleaching detergents containing hypochlorite are used to remove dark stains derived from bacteria and molds in bathrooms, toilets and sinks. These molds are generated not only on horizontally installed members such as floors and drain outlets, but also on vertically installed members such as bathroom and bathtub walls and window frames. As a method of removing mold generated on such vertical surfaces, the removal performance is improved by increasing the adhesion time to the object, such as improving foaming properties during spraying and increasing the solution viscosity. The method is known. For example, Patent Document 1 discloses that a liquid detergent containing hypochlorite is used in combination with two specific amine oxides such as octyl dimethylamine oxide and lauryl dimethylamine oxide, to adhere to a dirt surface. A liquid detergent composition with improved retention is disclosed.
また、従来の塩素系の漂白洗浄剤はタイルや目地、その他黒ずみ汚れに対して十分な効果を示したが、最近では、タイルや目地以外に、壁と浴槽等のつなぎ目に使用されているシリコーン樹脂系のコーキングや軟質ポリ塩化ビニル樹脂系のパッキンなどの樹脂部にカビが発生する例が増加してきており、タイルや目地に対して十分な効果を発揮していた従来の漂白洗浄剤であっても、これら樹脂部に発生したカビ汚れに対しては漂白洗浄力が十分であるとはいいがたく、樹脂部のカビ汚れに対して優れた漂白洗浄力を有する漂白剤組成物が求められている。このような要求に応えるべく、種々の方法による樹脂部のカビ汚れに対する漂白性能の向上が試みられている。例えば、特許文献２、３には、第４級アンモニウム型界面活性剤を含有する液体漂白剤組成物が開示されている。 In addition, conventional chlorine bleaching detergents have shown sufficient effects on tiles, joints, and other dark stains. Recently, in addition to tiles and joints, silicones used in the joints between walls and bathtubs are used. There are an increasing number of cases where mold occurs on resin parts such as resin-based caulking and soft polyvinyl chloride resin-based packing, and this is a conventional bleaching detergent that has been sufficiently effective against tiles and joints. However, it is difficult to say that bleaching detergency is sufficient for mold stains generated in these resin parts, and a bleaching composition having excellent bleaching detergency against mold stains in the resin part is required. ing. In order to meet such demands, attempts have been made to improve the bleaching performance of the resin part against mold stains by various methods. For example, Patent Documents 2 and 3 disclose liquid bleaching compositions containing a quaternary ammonium type surfactant.
しかしながら、従来提案されている方法では、垂直面に発生したカビ汚れを、短時間で除去することが困難であった。特許文献１の実施例では、泡の付着性や滞留性を評価しているが、実際の漂白性能、とりわけ垂直面に発生したカビ汚れに対する漂白性能については示されていない。 However, with the conventionally proposed method, it is difficult to remove mold stains generated on the vertical surface in a short time. In the examples of Patent Document 1, the adhesion and retention of foam are evaluated, but the actual bleaching performance, particularly the bleaching performance against mold stains generated on the vertical surface is not shown.
本発明の課題は、垂直面に発生したカビ汚れ等に対して、短時間で十分な除去ができる液体漂白剤組成物を提供することである。 An object of the present invention is to provide a liquid bleaching composition that can sufficiently remove mold stains and the like generated on a vertical surface in a short time.

Examples of the component (b) include sodium hydroxide and potassium hydroxide, and sodium hydroxide is particularly preferable. The component (b) is preferable as a component that improves the stability of the alkali metal hypochlorite that is the component (a).

When the content of the component (b) is 0.2% by mass or more, good alkali metal hypochlorite stability is obtained, and when it is 1% by mass or less, good bleaching performance is obtained.
［（ｃ）成分］
本発明の液体漂白剤組成物は、（ｃ１）成分のオクチルジメチルアミンオキサイドと（ｃ２）成分のデシルジメチルアミンオキサイドを合計で０．３〜２質量％、好ましくは０．５〜１．５質量％、更に好ましくは０．６〜１．２質量％含有する。また、（ｃ１）成分と（ｃ２）成分との質量比は、漂白性能の速効性の観点から、（ｃ１）／（ｃ２）＝９７／３〜７５／２５であり、好ましくは９７／３〜８０／２０、より好ましくは９５／５〜８０／２０である。
[Component (c)]
In the liquid bleach composition of the present invention, the total amount of octyldimethylamine oxide as the component (c1) and decyldimethylamine oxide as the component (c2) is 0.3 to 2% by mass, preferably 0.5 to 1.5% by mass. %, More preferably 0.6 to 1.2% by mass. In addition, the mass ratio of the component (c1) and the component (c2) is (c1) / (c2) = 97/3 to 75/25, preferably 97/3 to 75/25, from the viewpoint of quick action of bleaching performance. 80/20, more preferably 95/5 to 80/20.
本発明者らがカビ除去速度を向上させる方法を詳細に検討したところ、従来行われているような組成物の増粘や起泡性の向上といった観点とは異なる、特定の泡挙動を呈することにより、本発明の課題を解決しえることを見出した。すなわち、トリガー式スプレーヤーで噴霧した直後は起泡性が高く、付着性のある泡として対象物に付着させることが必要であるが、ある程度時間が経過した後、例えば５分程度経過した後には泡が崩壊することが重要であり、このような挙動を行うための液体漂白剤組成物、及び、トリガー式スプレーヤーを組み合わせることで本発明の課題を解決できることを見出した。このような泡挙動を呈することでなぜカビ汚れ除去速度が向上するかについての詳細は不明であるが、泡による付着性以外に、付着させた液体漂白剤組成物が空気中のＣＯ2を吸収してｐＨが低下することでカビ除去速度を改善でき、泡が崩壊することでＣＯ2の吸収を促進させることができるためと本発明者らは考えている。すなわち、泡安定性に優れる（ｃ２）成分と、泡安定性の低い（ｃ１）成分の所定比率での混合系が、スプレー直後の泡立ち性を高めると同時に、すみやかに泡を崩壊させるという泡挙動を発現させるために必須の組み合わせであると考えている。 When the present inventors have studied in detail a method for improving the mold removal rate, it exhibits a specific foam behavior that is different from conventional viewpoints such as thickening the composition and improving foaming properties. Thus, it has been found that the problems of the present invention can be solved. That is, it is highly foamable immediately after spraying with a trigger sprayer, and it is necessary to make it adhere to the object as sticky foam, but after a certain amount of time has passed, for example after about 5 minutes have passed It was important that bubbles collapse, and it was found that the problem of the present invention can be solved by combining a liquid bleach composition for performing such behavior and a trigger sprayer. The details of why the mold dirt removal rate is improved by exhibiting such foam behavior are unknown, but in addition to the adhesion due to foam, the adhered liquid bleach composition absorbs CO 2 in the air. The inventors believe that the mold removal rate can be improved by lowering the pH, and the absorption of CO 2 can be promoted by the collapse of the foam. That is, the foaming behavior that the mixing system of the component (c2) having excellent foam stability and the component (c1) having low foam stability at a predetermined ratio enhances foaming property immediately after spraying and at the same time quickly collapses the foam. It is considered to be an indispensable combination for the expression of.
