Description
本発明は、二酸化塩素を利用した洗浄剤に関する。より具体的には、本発明は、床面、壁面、窓、網戸、家具、バスタブ、シンク、便器等の洗浄に用いることができ、特に便蓋のボウル部側に設置する態様で好適に使用できる便器用洗浄剤に関する。 The present invention relates to a cleaning agent using chlorine dioxide. More specifically, the present invention can be used for cleaning floors, walls, windows, screen doors, furniture, bathtubs, sinks, toilet bowls, etc., and is particularly suitable for use when installed on the bowl side of a toilet lid. Regarding toilet bowl cleaners that can be used.
家庭や商業施設等において、室内や外観を衛生的な状態に保つことは、居住者や使用者等の健康維持はもちろん、快適で気分よく生活する上で重要である。これらの環境を衛生的な状態で維持するには洗浄が必要になるが、定期的に洗浄していても、水廻りでは皮脂等の人体由来の汚れ（水垢等）、黒ずみの発生を避けることができない。特に便器は、糞便の付着や水廻りでの黒ずみの発生が顕著である。そのため、水廻り、特に便器においては、定期的な洗浄だけでなく、汚れが生じた際にも擦り洗いが必要とされ、手間となっていた。このような手間を減らすために、例えば、便器の洗浄では、従来、便器の手洗い部、貯水タンク、リム部、ボウル部等に便器用洗浄剤を設置し、フラッシュ水に便器用洗浄剤を希釈させてボウル部に流水させることにより、ボウル部に付着する汚れや黒ずみの抑制や除去が行われている。 BACKGROUND ART In homes, commercial facilities, etc., keeping the interior and exterior in a sanitary state is important not only for maintaining the health of residents and users, but also for living comfortably and feeling well. Cleaning is necessary to maintain these environments in a sanitary state, but even if you clean regularly, it is important to avoid the occurrence of human body-derived dirt such as sebum (water scale, etc.) and dark spots around water areas. I can't. In particular, toilet bowls are particularly susceptible to fecal adhesion and darkening around the water area. Therefore, the plumbing, especially the toilet bowl, requires not only periodic cleaning but also scrubbing when it becomes dirty, which is time-consuming. In order to reduce this kind of effort, for example, when cleaning a toilet, conventionally, toilet bowl cleaners are placed in the hand wash area, water storage tank, rim, bowl, etc. of the toilet, and the toilet cleaner is diluted in flush water. By allowing water to flow through the bowl, dirt and dark spots adhering to the bowl are suppressed and removed.
しかしながら、擦り洗いが不要とされる従来の洗浄剤では、汚れを除去する効果（汚れ除去効果）が不十分であったり、当該汚れの付着を防止する効果（防汚効果）が不十分であったりするため、洗浄作用の点で十分に高いとはいえず、更なる改善が求められている。汚れの付着頻度、強固さの観点から、便器の汚れに対して汚れ除去効果や防汚効果を付与できる洗浄剤が求められており、当該洗浄剤は他の適用部位に対しても効果的であると考えられている。また、従来の便器用洗浄剤は、いずれもフラッシュ水に希釈させて使用されるため、洗浄作用が発揮されるのは、ボウル部においてフラッシュ水が通過する部分に限られるという点で改善が求められている。 However, with conventional cleaning agents that do not require scrubbing, the effect of removing dirt (stain removal effect) or the effect of preventing the adhesion of the dirt (antifouling effect) is insufficient. Therefore, it cannot be said that the cleaning effect is sufficiently high, and further improvement is required. There is a need for cleaning agents that can remove stains and provide antifouling effects for toilet bowl stains in terms of the frequency and hardness of stains, and these cleaning agents are also effective for other application areas. It is thought that there is. In addition, since all conventional toilet bowl cleaners are diluted with flush water, their cleaning action is limited to the area of the bowl through which the flush water passes, which requires improvement. It is being
このような従来技術を背景として、糞便や黒ずみといった強固な汚れに対する洗浄作用に優れ、便器においてはフラッシュ水が追加しない部分でも、擦り洗いすることなく、防汚効果等を発揮できる洗浄剤の開発が望まれている。 Based on this conventional technology, we have developed a cleaning agent that has excellent cleaning action against strong stains such as feces and blackheads, and can exhibit antifouling effects without scrubbing, even in areas where flush water is not added to the toilet bowl. is desired.
一方、二酸化塩素には、抗菌、除カビ、消臭、ウイルス除去等の作用があり、室内空間の清浄化に使用できることが知られているが（例えば、特許文献１及び２）、汚れ除去作用や防汚作用があることは知られていない。洗浄剤には、汚れ除去作用や防汚作用が必要とされるところ、二酸化塩素についてこれらの作用は知られておらず、特に二酸化塩素を含む便器用洗浄剤については報告されていない。 On the other hand, it is known that chlorine dioxide has antibacterial, mold removal, deodorizing, and virus removal effects, and can be used to clean indoor spaces (for example, Patent Documents 1 and 2), but it also has stain removal effects. It is not known that it has an antifouling effect. Cleaning agents are required to have stain removal and antifouling effects, but these effects are not known for chlorine dioxide, and in particular, there have been no reports on toilet bowl cleaners containing chlorine dioxide.
本発明の目的は、汚れ除去作用及び防汚作用が高く、優れた洗浄効果を奏する洗浄剤を提供することである。また、本発明の目的は、汚れ除去作用及び防汚作用が高く、洗浄効果が優れていることに加え、フラッシュ水で希釈しなくても便器のボウル部の洗浄を簡便に行うことができ、しかもフラッシュ水が通過しない便器のボウル部でも優れた防汚効果を付与し得る便器用洗浄剤を提供することである。 An object of the present invention is to provide a cleaning agent that has high stain removal and antifouling effects and exhibits excellent cleaning effects. In addition, the object of the present invention is to have high stain removal and antifouling effects and excellent cleaning effects, and also to be able to easily clean the bowl part of the toilet bowl without diluting it with flush water. Moreover, it is an object of the present invention to provide a toilet bowl cleaning agent that can provide excellent antifouling effects even in the bowl portion of the toilet bowl through which flush water does not pass.
本発明者は、前記課題を解決すべく鋭意検討を行ったところ、二酸化塩素には、優れた汚れ除去作用及び防汚作用があり、洗浄剤の洗浄成分として使用できることを見出した。更に、本発明者は、二酸化塩素を放出させる組成物を便器の便蓋のボウル部側等に設置して便蓋を閉めた状態にすると、当該組成物から放出されたガス状の二酸化塩素が便器のボウル部の表面全面、リム部（裏面部を含む）、及びリム部の内部（通水部）にまで二酸化塩素が行き渡り、これらの部位に防汚作用を付与できることを見出し、便器用洗浄剤として特に好適であることを発見した。本発明は、これらの知見に基づいて、更に検討を重ねることにより完成したものである。 The inventors of the present invention conducted extensive studies to solve the above problems and found that chlorine dioxide has excellent stain removal and antifouling effects and can be used as a cleaning component of cleaning agents. Furthermore, the present inventor has discovered that when a composition that releases chlorine dioxide is placed on the bowl side of the toilet lid of a toilet bowl and the toilet lid is closed, gaseous chlorine dioxide released from the composition is released. It was discovered that chlorine dioxide spreads over the entire surface of the bowl of the toilet bowl, the rim (including the back surface), and the inside of the rim (the water passage), giving these areas an antifouling effect. It has been discovered that it is particularly suitable as an agent. The present invention was completed through further studies based on these findings.

By including dissolved chlorine dioxide in the chlorine dioxide generating composition in this way, it becomes possible to release chlorine dioxide even more efficiently.
第２態様の組成物に溶存状態の二酸化塩素を含有させる場合、二酸化塩素の含有量については、水の含有量等に応じて適宜設定すればよいが、例えば、１０ｐｐｍ～１００００ｐｐｍ、好ましくは５０～６０００ｐｐｍが挙げられる。 When the composition of the second aspect contains dissolved chlorine dioxide, the content of chlorine dioxide may be set appropriately depending on the water content, etc., but for example, 10 ppm to 10,000 ppm, preferably 50 to 6000 ppm is mentioned.

For example, when water is not added or when a water-retaining base that retains water is contained, tablets, powders, granules, etc. may be used. In addition, when water is blended in a manner other than blending a water-retaining base that retains water, examples include liquid, gel, and paste forms.

It is desirable to set it to 1 ppm. By controlling the chlorine dioxide gas concentration in the internal space of the toilet bowl, which is formed when the toilet lid is closed, within the above range, it is possible to provide even better stain removal and antifouling effects. Become. The concentration of chlorine dioxide gas to be generated can be controlled by appropriately adjusting the content of chlorine dioxide contained in the chlorine dioxide releasing composition and/or the composition and content of the source of chlorine dioxide. When used in a space other than a toilet bowl, the chlorine dioxide gas concentration may be set to satisfy the above-mentioned chlorine dioxide gas concentration in a target space of a constant volume.

本発明の洗浄剤は、二酸化塩素の作用により、糞便等の付着した強固な汚れを除去する効果と共に、糞便の付着や黒ずみの原因となる汚れの付着を防止する効果があり、優れた洗浄作用を発揮できる。それ故、本発明の洗浄剤は、汚れ除去剤、又は防汚剤として使用することができる。
・Usage mode The cleaning agent of the present invention has the effect of removing stubborn stains such as feces due to the action of chlorine dioxide, and is also effective in preventing the adhesion of feces and stains that cause darkening. It can exert a cleaning effect. Therefore, the cleaning agent of the present invention can be used as a stain remover or an antifouling agent.
本発明の洗浄剤の洗浄対象については、特に制限されないが、例えば、床面、壁面、窓、網戸、家具、水廻り（バスタブ、シンク、排水パイプ等）、車、便器等が挙げられる。特に、本発明の洗浄剤は、陶磁器、金属、プラスチック、ガラス、コンクリート等で形成されている硬質表面の洗浄に好適である。また、水流洗浄による洗浄は、擦り洗いや浸け洗い等の場合と異なり、一般に洗浄効果が低いため、水流洗浄により洗浄される硬質表面は、汚垢を付着し難くしておくと共に、一旦汚垢が付着してもその除去が容易であるように処理されていることが重要であると考えられている。かかる課題と、本発明の効果を鑑みれば、本発明の洗浄剤は、水流洗浄によって洗浄される硬質表面の洗浄に特に好適に使用される。水流洗浄によって洗浄される硬質表面としては、具体的には、トイレの便器、浴槽、台所シンク、洗面ボウル、窓、タイル、外壁、車のボディー等が挙げられる。 The objects to be cleaned with the cleaning agent of the present invention are not particularly limited, but include, for example, floors, walls, windows, screen doors, furniture, plumbing areas (bathtubs, sinks, drainage pipes, etc.), cars, toilet bowls, and the like. In particular, the cleaning agent of the present invention is suitable for cleaning hard surfaces made of ceramics, metals, plastics, glass, concrete, and the like. In addition, cleaning with water jets is different from scrubbing or soaking, and the cleaning effect is generally low, so hard surfaces cleaned with water jets should be cleaned to make it difficult for dirt to adhere to them, and to remove dirt once the hard surfaces are cleaned. It is considered important that the treatment be such that even if it does adhere, it can be easily removed. In view of these problems and the effects of the present invention, the cleaning agent of the present invention is particularly suitably used for cleaning hard surfaces that are cleaned by water jet cleaning. Specific examples of hard surfaces that can be cleaned by flushing include toilet bowls, bathtubs, kitchen sinks, washbowls, windows, tiles, exterior walls, car bodies, and the like.
本発明の洗浄剤は、二酸化塩素放出組成物からガス状の二酸化塩素を放出させる態様で洗浄に使用してもよく、また二酸化塩素放出組成物から溶存状態の二酸化塩素を放出させる態様で洗浄に使用してもよい。ガス状の二酸化塩素を放出させる態様では、ガス状の二酸化塩素は空気よりも比重が高く、洗浄対象の表面全面に放出された二酸化塩素を行き渡らせることができ、特に便器ではフラッシュ水が接触しない箇所にも、汚れ除去効果及び防汚効果を付与することが可能になる。 The cleaning agent of the present invention may be used for cleaning in a manner in which gaseous chlorine dioxide is released from the chlorine dioxide releasing composition, or in a manner in which dissolved chlorine dioxide is released from the chlorine dioxide releasing composition. May be used. In the embodiment in which gaseous chlorine dioxide is released, gaseous chlorine dioxide has a higher specific gravity than air, and the released chlorine dioxide can be spread over the entire surface to be cleaned, and the flush water does not come into contact with it, especially in the toilet bowl. It becomes possible to impart stain removal effects and antifouling effects even to locations.
以下、ガス状の二酸化塩素を放出させる態様を「エアータイプの洗浄剤」、溶存状態の二酸化塩素を放出させる態様を「溶存タイプの洗浄剤」と表記し、それぞれについて、その使用態様を説明する。 Hereinafter, the mode of releasing gaseous chlorine dioxide will be referred to as "air-type cleaning agent", and the mode of releasing dissolved chlorine dioxide will be referred to as "dissolved-type cleaning agent", and the usage mode of each will be explained. .
［エアータイプの洗浄剤］
エアータイプの洗浄剤の場合、二酸化塩素放出組成物は、仕切られた内部空間に取り付けることが望ましい。例えば、エアータイプの洗浄剤を便器用洗浄剤とする場合、便蓋のボウル部側の表面、ボウル部表面、リム部等の、便蓋を閉めた際に形成される便器の内部空間の壁面に取り付けられる。このような部位に設置された二酸化塩素放出組成物は、便器の便蓋を閉めた状態になっている際に、便器の便蓋とボウル部等で形成された空間内にガス状の二酸化塩素を放出し、ボウル部の表面全面、リム部（裏面部を含む）、リム部内部（通水部）に二酸化塩素を行き渡らせて、フラッシュ水が接触しない部位にも汚れ除去効果及び防汚効果を付与することができる。
[Air type cleaning agent]
In the case of air-type cleaners, the chlorine dioxide releasing composition is desirably installed in a partitioned interior space. For example, when an air-type cleaning agent is used as a toilet bowl cleaning agent, the walls of the internal space of the toilet formed when the toilet lid is closed, such as the bowl-side surface of the toilet lid, the bowl surface, and the rim. can be attached to. The chlorine dioxide releasing composition installed in such areas releases gaseous chlorine dioxide into the space formed by the toilet lid and bowl when the toilet lid is closed. The chlorine dioxide is distributed over the entire surface of the bowl, the rim (including the back surface), and the inside of the rim (water passage area), providing stain removal and antifouling effects even in areas that are not contacted by flush water. can be granted.
エアータイプの洗浄剤を便器用洗浄剤とする場合、洋式便器、和式便器、和式便器を簡易に洋式に変更する改造用便器・便座が取り付けられた便器、ポータブル便器等のいずれにも使用できるが、好ましくは洋式便器が挙げられる。 When air-type cleaning agents are used as toilet bowl cleaners, they can be used for Western-style toilets, Japanese-style toilets, modified toilets for easily changing Japanese-style toilets to Western-style toilets, toilets with toilet seats attached, portable toilets, etc. However, a Western-style toilet bowl is preferred.
ここで、和式便器の場合には、前記便蓋はトイレカバーに該当し、前記ボウル部とは便器容器に該当する。また、便器のリム部とは、洋式便器においてはボウル部の上端において便座を載置する役割を果たし、和式便器においては便器を設置した床面と近接した位置に存在し、通常、洋式便器のリム部の内部にはフラッシュ水を誘導するための通水部（通水路）がある。 Here, in the case of a Japanese-style toilet bowl, the toilet lid corresponds to a toilet cover, and the bowl part corresponds to a toilet container. In addition, the rim part of a toilet bowl plays the role of placing the toilet seat at the upper end of the bowl part in a Western-style toilet bowl, and in a Japanese-style toilet bowl it is located close to the floor surface on which the toilet is installed. There is a water passage part (water passage) inside the rim part for guiding flush water.
エアータイプの洗浄剤を便器用洗浄剤としてボウル部又はリム部に設置する場合、当該設置部位は、フラッシュ水と接触する部位であってもよく、フラッシュ水と接触しない部位であってもよい。 When installing an air-type cleaning agent as a toilet bowl cleaning agent in the bowl or rim, the installation site may be a site that comes into contact with flush water or a site that does not come into contact with flush water.
