【発明の属する技術分野】
本発明は、水が貯められた空間を規定する壁面を洗浄するために用いられる洗浄剤および洗浄方法、特に、水洗便器、浴槽、洗濯機の洗濯槽等の内壁面の洗浄に適する洗浄剤および洗浄方法に関する。
【０００２】
【従来の技術】
従来、水洗便器、浴槽、洗濯槽等の内壁面を洗浄するための洗浄剤として、活性塩素を含む次亜塩素酸ソーダ、次亜塩素酸カルシウム、イソシアヌル酸のトリクロロ塩、イソシアヌル酸のジクロロ塩等を主成分とする組成物や、活性酸素を含む過炭酸ソーダを主成分とする組成物が別個に用いられている。
【０００３】
【発明が解決しようとする課題】
前記従来の洗浄剤は、これを水洗便器、浴槽、洗濯槽等に貯められた水の中に入れて使用する。前記洗浄剤は、水中で溶解し、前記洗浄剤の成分である活性塩素または活性酸素が前記水洗便器、浴槽、洗濯槽等の内壁面に対して強い殺菌作用、漂白作用、洗浄作用等を及ぼす。その結果、前記内壁面に付着した水垢、黴、水性微生物の集まりであるいわゆるスライム等が除去され、前記内壁面が洗浄される。
【０００４】
ところで、前記活性塩素または前記活性酸素は洗浄終了後に自然に消失することはない。このため、洗浄終了後の水洗便器、浴槽、洗濯槽等から前記洗浄剤の水溶液を排出すると、例えば排水浄化槽中の微生物のような有効菌が、前記水溶液中の活性塩素または活性酸素の殺菌作用および漂白作用によってその成育を阻害されあるいは死滅される。その結果、排水の浄化が阻害されるという問題があった。
【０００５】
本発明の目的は、活性塩素または活性酸素による洗浄効果が得られ、また、洗浄後は活性塩素または活性酸素が消失する、洗浄剤および洗浄方法を提供することにある。
【０００６】
【課題を解決するための手段】
本発明に係る洗浄剤は、活性酸素を発生する洗浄剤成分として過炭酸ソーダまたは過硼酸ソーダを含む水溶性の第１の組成物と、前記第１の組成物とは独立した、前記活性酸素の全量を中和するのに必要な量の中和剤成分としてさらし粉または塩素化イソシアヌル酸を含む水溶性の第２の組成物とを含み、水への溶解に要する時間に関して前記第１の組成物が前記第２の組成物より短い。前記第１の組成物が粉末または顆粒からなり、かつ前記第２の組成物が固形物（錠剤）からなるものとし、あるいは前記第１の組成物および前記第２の各組成物がそれぞれ固形物（錠剤）からなり、前記第１の組成物が崩壊剤を含むものとすることができる。
【０００７】
前記崩壊剤は例えば炭酸水素ナトリウムと有機酸とからなる。
【０００８】
また、前記第１および第２の両組成物が、それぞれ、蔗糖脂肪酸エステルおよびカルボキシメチルセルロースを含むものとすることができる。
【０００９】
本発明に係る洗浄方法は、洗浄対象を水が貯められた空間を規定する壁面とし、水中に、活性酸素を発生する洗浄剤成分として過炭酸ソーダまたは過硼酸ソーダを含む水溶性の第１の組成物と、前記活性酸素の全量を中和するのに必要な量の中和剤成分としてさらし粉または塩素化イソシアヌル酸を含む水溶性の第２の組成物であって前記第１の組成物とは独立した、また、水に対する溶解時間が前記第１の組成物より長い第２の組成物とを同時に入れる。ここにおいて、前記第１の組成物が粉末または顆粒からなり、かつ前記第２の組成物が固形物（錠剤）からなり、あるいは前記第１の組成物および前記第２の各組成物がそれぞれ固形物（錠剤）からなり、前記第１の組成物が崩壊剤を含む。
【００１０】
また、本発明に係る他の洗浄方法は、水中に、活性酸素を発生する洗浄剤成分として過 炭酸ソーダまたは過硼酸ソーダを含む水溶性の第１の組成物を入れ、その後、前記活性酸素の全量を中和するのに必要な量の中和剤成分としてさらし粉または塩素化イソシアヌル酸を含む水溶性の第２の組成物を入れる。ここにおいて、前記第１の組成物が粉末または顆粒からなり、かつ前記第２の組成物が固形物（錠剤）からなるものとし、あるいは前記第１の組成物および前記第２の各組成物がそれぞれ固形物（錠剤）からなり、前記第１の組成物が崩壊剤を含むものとすることができる。
【００１１】
【発明の作用および効果】
本発明によれば、前記第１の組成物の水に対する溶解時間が前記第２の組成物より短いことから、第１および第２の各組成物の水中における溶解過程において、両組成物の溶解量または濃度に差を生じさせることができる。すなわち、所定の時間、前記第１の組成物の濃度を前記第２の組成物の濃度より高いものとし、前記第２の組成物の中和剤成分が前記第１の組成物の活性酸素を完全に中和する量に満たない状態を維持することができ、これにより、前記活性酸素を不完全中和の状態におくことができる。不完全中和状態における非中和の活性酸素は強い殺菌作用、漂白作用、洗浄作用等を有する。これらの殺菌作用、漂白作用、洗浄作用等は、前記活性酸素の全量が完全に中和されるとき、好ましくは前記第２の組成物が完全に溶解し、その中和剤成分の濃度が前記活性酸素の濃度と等しくなったときに消失する。完全な中和により、前記活性酸素の活性が消失することから、本発明の洗浄剤が溶解した水溶液を排水するとき、排水浄化槽中の微生物のような有効菌の成育が阻害されあるいはこのような有効菌が死滅されることはない。したがって、本発明の洗浄剤は水洗便器や、浴槽内、洗濯槽等の内壁面の洗浄に特に適するということができる。
【００１２】
前記第１の組成物を水に溶けやすい形態である粉末または顆粒からなるものとし、前記第２の組成物を前記粉末または顆粒より水に溶けにくい形態である固形物（錠剤）からなるものとすることにより、水中での前記第１の組成物の溶解時間を前記第２の組成物の溶解時間より短いものに設定することができる。また、前記第１および第２の組成物をそれぞれ固形物（錠剤）からなるものとし、かつ、前記第１の組成物が崩壊剤を含むものとすることによっても、前記第１の組成物がより水に溶けやすいようにし、水中での前記第１の組成物の溶解時間を前記第２の組成物のそれより短いものに設定することができる。前記崩壊剤は炭酸水素ナトリウム（重曹）とクエン酸のような有機酸とからなるものとすることができ、これによれば、前記炭酸水素ナトリウムと有機酸とが水と反応して炭酸ガスを発生し、これが前記固形物からなる第１の組成物を崩壊させる。崩壊した第１の組成物は、固形状態の前記第２の組成物に比べて短時間で水中に溶解する。
【００１３】
両組成物が蔗糖脂肪酸エステルおよびカルボキシメチルセルロースを含むものとすると、前記蔗糖脂肪酸エステルおよびカルボキシメチルセルロースは、両組成物が水に溶解して前記活性酸素を発生する洗浄剤成分と前記中和剤成分とが中和反応するときに生じるガスを内包する、両組成物が水に溶解した水溶液の一部からなる多数の泡に変化する。これらの多数の泡は、前記水溶液の上方空間に広がり、前記多数の泡は、前記水溶液が接しない前記非洗浄面の一部にも洗浄作用を及ぼす。これは、水位が定まっている水洗便器の洗浄に特に適する。
【００１４】
水が貯められた空間を規定する壁面の洗浄のため、水中に前記第１の組成物と前記第２の組成物とを同時に入れることにより、あるいは、前記洗浄剤成分を含む第１の組成物を入れ、その後、前記中和剤成分を含む第２の組成物を入れることにより、水中における前記第１の組成物の溶解量が前記第２の組成物の溶解量を一時的に上回るようにすることができる。これにより、前記第１の組成物から溶解した活性酸素による前記壁面に対する洗浄作用と、前記第２の組成物から溶解した中和剤成分による前記活性酸素の完全中和およびこれに伴う排水経路上における微生物のような有効菌に対する無害化とを実現することができる。
【００１５】
【発明の実施の形態】
本発明に係る洗浄剤は、水が貯められた空間を規定する壁面、例えば、水洗便器、浴槽、洗濯機の洗濯槽等の内壁面を洗浄するために用いられ、使用の際、水中に投入される。
【００１６】
本発明の洗浄剤は、活性塩素および活性酸素のいずれか一方を洗浄剤成分として含む水溶性の第１の組成物と、前記第１の組成物とは独立した、すなわち前記第１の組成物とは分離された、活性塩素または活性酸素の全量を中和するのに必要な量の中和剤成分を含む水溶性の第２の組成物とを含み、前記第１の組成物は、水への溶解に要する時間に関して、前記第２の組成物より短い。
【００１７】
前記活性塩素を含む洗浄剤成分として、例えばさらし粉、塩素化イソシアヌル酸等を用いることができ、また、前記活性酸素を含む洗浄剤成分として、例えば過炭酸ソーダ、過硼酸ソーダ等を用いることができる。前記活性塩素および前記活性酸素は、共に、強い漂白作用、殺菌作用、洗浄作用等を有する。
【００１８】
他方、前記活性塩素を中和するための中和剤成分として、例えば過炭酸ソーダ、過硼酸ソーダ等を用いることができる。また、前記活性酸素を中和するための中和剤成分として、さらし粉、塩素化イソシアヌル酸等を用いることができる。これらの中和剤成分は、強い漂白作用、殺菌作用、洗浄作用等を有するため、後述する排水後のことを考慮して、前記活性塩素または活性酸素の全量を中和するのに必要かつ十分な量（中和当量）とすることが望ましい。但し、前記中和剤成分が前記したような作用を有しない、毒性の低い、低公害性のものであれば、前記活性塩素または活性酸素の全量を中和するに足る量以上に設定してもよい。
【００１９】
本発明の前記洗浄剤の使用に当たり、前記第１および第２の両組成物を前記壁面で囲まれた水中に同時に入れる。前記第１の組成物は前記第２の組成物より早く水に溶ける。例えば、前記第２の組成物中の中和剤成分の量が、前記第１の組成物中の活性塩素または活性酸素の全量を中和するのに過不足のない量である中和当量である場合、前記第２の組成物が完全に溶解するまでの間、前記第１の組成物の溶解濃度は前記第２の組成物の溶解濃度より大きい。したがって、水中において、前記第２の組成物から溶解した全ての中和剤成分が前記活性塩素または前記活性酸素の一部を中和するが、残りは中和されない。中和されなかった残りの活性塩素または前記活性酸素は、前記壁面に対して殺菌作用、漂白作用、洗浄作用等を及ぼし、前記壁面に付着した水垢、黴、スライム等を除去し、これにより前記壁面が洗浄される。時間の経過に従って、前記第２の組成物の溶解量すなわち濃度は増大し、完全に溶解するとき、前記活性塩素または前記活性酸素の全てが前記中和剤成分により中和され、活性を失い、単なる塩素または酸素となる。塩素または酸素が溶解した水溶液は、これを排出するとき、排水浄化槽中の微生物のような有効菌の成育を阻害しあるいはこのような有効菌を死滅させることはない。
【００２０】
前記第１および第２の両組成物を水中に同時に投じることに代えて、先に前記第２の組成物を水に入れ、その後、前記第１の組成物を水中に投入してもよい。但し、この場合には、前記第２の組成物の水中投入後、前記第１および第２の両組成物の溶解時間の差の範囲内で、好ましくは、できる限り短時間の内に、前記第１の組成物を水中に投入する。
【００２１】
また、前記第１および第２の両組成物を水中に同時に投じることに代えて、前記第１の組成物を先に水に投入し、その後、前記第２の組成物を水中に投入してもよい。この場合には、前記第１および第２の両組成物の水に対する溶解時間、すなわち完全に水に溶ける時間が同じであってもよい。これによれば、前記第２の組成物が水に投入されるまでの間に溶解した前記第１の組成物の一部の活性塩素または活性酸素が洗浄効果を発揮する。
【００２２】
前記第１の組成物の溶解時間を前記第２の組成物の溶解時間より短いものに設定するには、例えば、第１および第２の各組成物を固形物（錠剤）としかつ前記第１の組成物中に崩壊剤を含める。前記崩壊剤は、例えば、炭酸水素ナトリウムとクエン酸のような有機酸とからなり、これらは水と反応して炭酸ガスを発生する。前記炭酸ガスの発生により前記固形物からなる第１の組成物が崩壊し、前記第１の組成物の水に対する接触面積が大きくなる。このため、前記第１の組成物は前記第２の組成物より短時間で水に溶解する。
【００２３】
また、前記第１の組成物を粉末または顆粒からなるものとし、前記第２の組成物を前記固形物からなるものとしてもよい。前記粉末または顆粒は、前記固形物に比べて、水に溶けやすいから、水中における前記第１の組成物の溶解時間は前記第２の組成物の溶解時間より短い。
【００２４】
前記第１の組成物および前記第２の組成物の少なくとも一方に、蔗糖脂肪酸エステルおよびカルボキシメチルセルロースの双方を含めることができる。前記蔗糖脂肪酸エステルは、前記洗浄剤成分と前記中和剤成分との中和反応、例えば、ジクロロイソシアヌル酸ソーダと、過炭酸ソーダとの間に中和反応が生じるとき発生する炭酸ガスを内部に含む多数の気泡を形成し、前記カルボキシメチルセルロースは前記気泡の寿命の増大に寄与する。このようにして生じる前記多数の気泡は、本発明の洗浄剤が水に溶解してなる水溶液の液面上方に広がる。前記気泡は、前記水溶液の一部からなることから、該水溶液と同様の洗浄力を有する。したがって、この例は、水面が一定の高さ位置にある水洗便器の洗浄に特に適し、前記気泡により前記水洗便器の水面上方の壁面を洗浄することができる。
【００２５】
また、前記第１の組成物中にトリポリ燐酸ソーダのような防錆剤成分を含めれば、特に、前記壁面がステンレス鋼のような金属材料で形成されている場合、前記活性塩素または前記活性酸素による前記金属材料に対する侵食を防止（防錆）することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a cleaning agent and a cleaning method used for cleaning a wall surface that defines a space in which water is stored, particularly a cleaning agent suitable for cleaning an inner wall surface of a flush toilet, a bathtub, a washing tub of a washing machine, and the like. The present invention relates to a cleaning method.
[0002]
[Prior art]
Conventionally, as a cleaning agent for cleaning inner wall surfaces of flush toilets, bathtubs, washing tubs, etc., sodium hypochlorite containing active chlorine, calcium hypochlorite, trichloro salt of isocyanuric acid, dichloro salt of isocyanuric acid, etc. And a composition mainly composed of sodium percarbonate containing active oxygen are used separately.
[0003]
[Problems to be solved by the invention]
The conventional cleaning agent is used by putting it in water stored in a flush toilet, a bathtub, a washing tub or the like. The cleaning agent dissolves in water, and active chlorine or active oxygen, which is a component of the cleaning agent, exerts a strong sterilizing action, bleaching action, cleaning action, etc. on the inner wall surface of the flush toilet, bathtub, washing tub, etc. . As a result, scales, soot, and so-called slime that are a collection of aqueous microorganisms attached to the inner wall surface are removed, and the inner wall surface is washed.
[0004]
By the way, the active chlorine or the active oxygen does not disappear spontaneously after completion of the cleaning. For this reason, when the aqueous solution of the cleaning agent is discharged from a flush toilet, a bathtub, a washing tub, etc. after completion of cleaning, effective bacteria such as microorganisms in a wastewater septic tank are sterilized by active chlorine or active oxygen in the aqueous solution. And its growth is inhibited or killed by bleaching action. As a result, there has been a problem that purification of waste water is hindered.
[0005]
An object of the present invention is to provide a cleaning agent and a cleaning method in which a cleaning effect by active chlorine or active oxygen is obtained, and active chlorine or active oxygen disappears after cleaning.
[0006]
[Means for Solving the Problems]
The cleaning agent according to the present invention includes a water-soluble first composition containing sodium percarbonate or sodium perborate as a cleaning agent component that generates active oxygen, and the active oxygen independent of the first composition. A water-soluble second composition containing bleached powder or chlorinated isocyanuric acid as a neutralizing agent component in an amount necessary to neutralize the total amount of the first composition with respect to the time required for dissolution in water The product is shorter than the second composition. The first composition is made of powder or granules, and the second composition is made of a solid (tablet) , or each of the first composition and the second composition is a solid. It consists (tablet), wherein the first composition may be intended to include a disintegrant.
[0007]
The disintegrant is made of, for example, sodium hydrogen carbonate and an organic acid.
[0008]
Moreover, the said 1st and 2nd composition shall respectively contain a sucrose fatty acid ester and carboxymethylcellulose.
[0009]
In the cleaning method according to the present invention, a water-soluble first water-containing first solution containing sodium percarbonate or sodium perborate as a cleaning agent component that generates active oxygen in water is used as a cleaning target wall surface that defines a space in which water is stored. A water-soluble second composition comprising bleaching powder or chlorinated isocyanuric acid as a neutralizing agent component in an amount necessary to neutralize the total amount of the active oxygen, and the first composition; And a second composition which is independent and has a longer dissolution time in water than the first composition. Here, the first composition is made of powder or granules, and the second composition is made of a solid (tablet) , or the first composition and the second composition are each solid. The first composition comprises a disintegrant.
[0010]
Another cleaning method according to the present invention, the water, the first composition of a water-soluble comprising sodium percarbonate or sodium perborate placed as a cleaning component that generates active oxygen, then the active oxygen A water soluble second composition containing bleached powder or chlorinated isocyanuric acid is added as a neutralizing agent component in an amount necessary to neutralize the total amount. Wherein the first composition is a powder or granules, and the second composition consisted of solids (tablets), or the first composition and the second of each composition each consists solids (tablets), said first composition disintegrants may be Dressings containing.
[0011]
Operation and effect of the invention
According to the present invention, since the dissolution time of the first composition in water is shorter than that of the second composition, the dissolution of both compositions in the dissolution process of the first and second compositions in water. Differences in amount or concentration can be made. That is, for a predetermined time, the concentration of the first composition is higher than the concentration of the second composition, and the neutralizing agent component of the second composition causes the active oxygen of the first composition to increase. A state of less than the amount to be completely neutralized can be maintained, whereby the active oxygen can be in an incompletely neutralized state. Non-neutralized active oxygen in an incompletely neutralized state has a strong bactericidal action, bleaching action, washing action and the like. These bactericidal action, bleaching action, cleaning action, etc. are preferably such that when the total amount of the active oxygen is completely neutralized, the second composition is completely dissolved, and the concentration of the neutralizer component is It disappears when it becomes equal to the concentration of active oxygen. When the aqueous solution in which the cleaning agent of the present invention is dissolved is drained by the complete neutralization, the growth of effective bacteria such as microorganisms in the waste water septic tank is inhibited or such Effective bacteria are not killed. Therefore, it can be said that the cleaning agent of the present invention is particularly suitable for washing flush toilet bowls, inner walls of bathtubs, washing tubs and the like.
[0012]
The first composition is made of powder or granules that are easily soluble in water, and the second composition is made of a solid material (tablet) that is less soluble in water than the powder or granules. By doing this, the dissolution time of the first composition in water can be set to be shorter than the dissolution time of the second composition. In addition, the first composition is made of a solid material (tablet), and the first composition contains a disintegrant, so that the first composition is more water-soluble. The dissolution time of the first composition in water can be set to be shorter than that of the second composition. The disintegrant may be composed of sodium hydrogen carbonate (sodium bicarbonate) and an organic acid such as citric acid. According to this, the sodium hydrogen carbonate and the organic acid react with water to generate carbon dioxide gas. Occurs, causing the first composition comprising the solid to collapse. The disintegrated 1st composition melt | dissolves in water in a short time compared with the said 2nd composition of a solid state.
[0013]
Assuming that both compositions contain a sucrose fatty acid ester and carboxymethyl cellulose, the sucrose fatty acid ester and carboxymethyl cellulose are composed of a detergent component that dissolves both in water to generate the active oxygen and the neutralizer component. The two compositions change into a large number of bubbles made of a part of an aqueous solution in which the gas generated during the neutralization reaction is contained and dissolved in water. The large number of bubbles spread in the upper space of the aqueous solution, and the large number of bubbles also exerts a cleaning action on part of the non-cleaning surface that is not in contact with the aqueous solution. This is particularly suitable for washing flush toilets with fixed water levels.

The first composition containing the cleaning agent component by simultaneously putting the first composition and the second composition into water for cleaning the wall surface defining the space in which water is stored And then adding a second composition containing the neutralizing agent component so that the amount of the first composition dissolved in water temporarily exceeds the amount of the second composition dissolved. can do. Thereby, the cleaning action on the wall surface by the active oxygen dissolved from the first composition, the complete neutralization of the active oxygen by the neutralizing agent component dissolved from the second composition, and the drainage path associated therewith It is possible to achieve detoxification against effective bacteria such as microorganisms.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The cleaning agent according to the present invention is used for cleaning wall surfaces that define a space in which water is stored, for example, inner wall surfaces of flush toilets, bathtubs, washing tubs, etc., and is put into water when used. Is done.
[0016]
The cleaning agent of the present invention includes a water-soluble first composition containing any one of active chlorine and active oxygen as a cleaning agent component, and the first composition, that is, the first composition. And a water-soluble second composition containing a neutralizer component in an amount necessary to neutralize the total amount of active chlorine or active oxygen, and the first composition comprises water. The time required for dissolution in is shorter than that of the second composition.
[0017]
As the detergent component containing active chlorine, for example, bleaching powder, chlorinated isocyanuric acid and the like can be used, and as the detergent component containing active oxygen, for example, sodium percarbonate, sodium perborate and the like can be used. . Both the active chlorine and the active oxygen have a strong bleaching action, bactericidal action, cleaning action and the like.
[0018]
On the other hand, as a neutralizing agent component for neutralizing the active chlorine, such as sodium percarbonate, Ru can be used sodium perborate and the like. Further, bleaching powder, chlorinated isocyanuric acid, or the like can be used as a neutralizing agent component for neutralizing the active oxygen. These neutralizer components have a strong bleaching action, sterilization action, cleaning action, etc., so that they are necessary and sufficient to neutralize the total amount of active chlorine or active oxygen in consideration of after drainage described later. It is desirable to make it a proper amount (neutralization equivalent). However, if the neutralizing agent component does not have the above-described action, has low toxicity, and has low pollution, it is set to an amount sufficient to neutralize the total amount of the active chlorine or active oxygen. Also good.
[0019]
In using the cleaning agent of the present invention, both the first and second compositions are simultaneously put into water surrounded by the wall surface. The first composition dissolves in water faster than the second composition. For example, the amount of the neutralizing agent component in the second composition is a neutralization equivalent amount that is sufficient to neutralize the total amount of active chlorine or active oxygen in the first composition. In some cases, the dissolution concentration of the first composition is greater than the dissolution concentration of the second composition until the second composition is completely dissolved. Accordingly, in water, all neutralizer components dissolved from the second composition neutralize part of the active chlorine or active oxygen, but the rest are not neutralized. The remaining active chlorine that has not been neutralized or the active oxygen has a bactericidal action, a bleaching action, a cleaning action, etc. on the wall surface, and removes scales, soot, slime, etc. adhering to the wall surface, thereby The wall is cleaned. Over time, the dissolved amount or concentration of the second composition increases, and when completely dissolved, all of the active chlorine or the active oxygen is neutralized by the neutralizer component and loses activity, It becomes just chlorine or oxygen. When the aqueous solution in which chlorine or oxygen is dissolved is discharged, it does not inhibit the growth of effective bacteria such as the microorganisms in the waste water septic tank or kill such effective bacteria.
[0020]
Instead of simultaneously pouring both the first and second compositions into water, the second composition may be put into water first, and then the first composition may be put into water. However, in this case, after charging the second composition in water, within the range of the difference in dissolution time between the first and second compositions, preferably within as short a time as possible. The first composition is poured into water.
[0021]
Also, instead of throwing both the first and second compositions into water at the same time, the first composition is poured into water first, and then the second composition is poured into water. Also good. In this case, the dissolution time of both the first and second compositions in water, that is, the time for complete dissolution in water may be the same. According to this, a part of active chlorine or active oxygen of the first composition dissolved until the second composition is put into water exhibits a cleaning effect.
[0022]
In order to set the dissolution time of the first composition to be shorter than the dissolution time of the second composition, for example, each of the first and second compositions is a solid (tablet) and the first composition A disintegrant is included in the composition. The disintegrant is composed of, for example, sodium hydrogen carbonate and an organic acid such as citric acid, and these react with water to generate carbon dioxide gas. Generation of the carbon dioxide gas causes the first composition composed of the solid material to collapse, and the contact area of the first composition with water increases. For this reason, the first composition dissolves in water in a shorter time than the second composition.
[0023]
Further, the first composition may be made of powder or granules, and the second composition may be made of the solid material. Since the powder or granule is more soluble in water than the solid, the dissolution time of the first composition in water is shorter than the dissolution time of the second composition.
[0024]
At least one of the first composition and the second composition can include both a sucrose fatty acid ester and carboxymethylcellulose. The sucrose fatty acid ester contains a carbon dioxide gas generated when a neutralization reaction between the detergent component and the neutralizer component, for example, a neutralization reaction occurs between sodium dichloroisocyanurate and sodium percarbonate. A large number of bubbles are formed, and the carboxymethyl cellulose contributes to an increase in the lifetime of the bubbles. The numerous bubbles generated in this way spread above the surface of an aqueous solution obtained by dissolving the cleaning agent of the present invention in water. Since the bubbles are part of the aqueous solution, they have the same detergency as the aqueous solution. Therefore, this example is particularly suitable for washing a flush toilet with the water surface at a certain height, and the wall above the flush surface of the flush toilet can be washed by the bubbles.
[0025]
Further, if a rust inhibitor component such as sodium tripolyphosphate is included in the first composition, particularly when the wall surface is formed of a metal material such as stainless steel, the active chlorine or the active oxygen It is possible to prevent (rust prevention) the erosion of the metal material due to.
