Description
本発明は、界面活性剤等の洗剤の使用量を極力少なくし、電解水の特性を利用して、対象物を除菌洗浄するための洗浄剤及びこれを用いた汚染物の除去方法に関する。 The present invention relates to a cleaning agent for sterilizing and cleaning an object using the characteristics of electrolyzed water by reducing the amount of detergent such as a surfactant as much as possible, and a method for removing contaminants using the same.
床などの清掃に用いる界面活性剤は、極力汚れを落とすため、環境ホルモン類、毒性化学物質、有機溶剤を使用することが多い。このため、廃液処理の問題も生じて、清掃業者にとっても負荷がかかることもある。更に、その廃液が生物に与える影響も少なくなく、環境にやさしい洗剤の開発が今日期待されている。更に、洗剤等のコストも清掃業者を圧迫していることも事実である。 Surfactants used for cleaning floors and the like often use environmental hormones, toxic chemicals, and organic solvents to remove dirt as much as possible. For this reason, the problem of waste liquid treatment also arises, and it may be burdensome for the cleaning contractor. Furthermore, the development of environmentally friendly detergents is expected today because the waste liquid has little impact on living organisms. Furthermore, it is also true that the cost of detergents etc. is putting pressure on cleaners.
今日、気泡の表面は、活性が高く、汚れを蓄えやすい性質がり、水の中の汚れを取り除いたり、工業製品の洗浄を可能にすることが知られている。特に、同じ体積の気体であれば、大きな気泡よりも小さな気泡をたくさん使ったほうが、より効果的に汚れが落とせることが知られている。一方で、現状の清掃方法では、界面活性剤の使用量が多すぎるという問題がある。このことは、清掃業者のコスト高につながる。更に、廃液処理に伴う生物の環境への影響が懸念され、地球にやさしい界面活性剤等の開発がされている。 Today, it is known that the surface of bubbles is highly active and has a property of easily storing dirt, which can remove dirt in water and clean industrial products. In particular, it is known that if the gas has the same volume, it is possible to remove dirt more effectively by using many small bubbles than large bubbles. On the other hand, the current cleaning method has a problem that the amount of the surfactant used is too large. This leads to high costs for the cleaner. Furthermore, there are concerns about the impact of living organisms on the environment associated with waste liquid treatment, and the development of surfactants that are kind to the earth has been underway.
例えば、特許文献１（特開２００１−３０３０９６号公報）では、洗浄力を維持しながら環境へ排出する負荷を軽減する洗浄剤として、アルキレンテレフタレート及び／又はアルキレンイソフタレート単位とポリオキシアルキレン単位を基本骨格とする高分子化合物を主成分とする洗浄剤が開示されている。 For example, in Patent Document 1 (Japanese Patent Laid-Open No. 2001-303096), an alkylene terephthalate and / or alkylene isophthalate unit and a polyoxyalkylene unit are basically used as a cleaning agent that reduces the load discharged to the environment while maintaining the cleaning power. A cleaning agent mainly composed of a polymer compound having a skeleton is disclosed.
また、特許文献２（特開平１０−２７７０５１号公報）では、ペルオキソ酸塩を主成分とし、所望に応じて界面活性剤を含む洗浄剤が開示されている。
しかしながら、これらの先行技術は、あくまでも洗浄剤そのものの成分に関するものであり、環境への負荷をある程度は軽減できるものの、界面活性剤を使用を抑制するという根本的な課題を解決するものではない。
Patent Document 2 (Japanese Patent Laid-Open No. 10-277051) discloses a cleaning agent containing a peroxoacid salt as a main component and a surfactant as desired.
However, these prior arts relate only to the components of the cleaning agent itself, and although the environmental load can be reduced to some extent, it does not solve the fundamental problem of suppressing the use of a surfactant.
一方、洗浄と同時に除菌、消毒等を行う用途は、食品関連業界、老人介護業界、医療業界などの種々の分野で要望されている。
例えば、食品関連業界においては、食器、食材、調理具などを洗浄、除菌を行う必要があるだけでなく、長期間の調理により付着した油に起因する汚れを洗浄したいという要望がある。このような油汚れには、微生物が付着し、付着した微生物が食品などに落下して食品の変敗、腐敗を速める場合がある。
このような厨房機器を除菌する場合には主として塩素系の除菌剤を使用しているが、これらの塩素系の除菌剤は作業者の安全性の問題だけでなく、除菌剤が食品に混入して食品の品質を劣化させてしまうことがある。
For example, in the food-related industry, there is a demand not only to clean and sterilize tableware, foodstuffs, cooking utensils, etc., but also to clean dirt caused by oil attached by long-term cooking. There are cases where microorganisms adhere to such oil stains, and the attached microorganisms fall on food and the like, thereby speeding up the deterioration and decay of food.
When sterilizing such kitchen equipment, chlorine-based disinfectants are mainly used, but these chlorine-based disinfectants are not only a safety issue for workers, but also disinfectants. It may be mixed with food and deteriorate the quality of food.
従って、本発明の課題は、界面活性剤の使用を回避して十分な洗浄効果を発揮することが可能であり、なおかつ除菌効果を有する洗浄剤を提供することである。 Accordingly, an object of the present invention is to provide a cleaning agent capable of avoiding the use of a surfactant and exhibiting a sufficient cleaning effect and having a sterilizing effect.

本発明の除菌洗浄剤において、前記電解水はアルカリ水側の電解水が主成分であることを特徴とする（請求項２）。
本発明の除菌洗浄剤は、容器、例えば、プラスチック容器に収納されていることが好ましい（請求項３）。
本発明の除菌洗浄剤は、界面活性剤を含まないことが好ましい（請求項４）。
The present invention for solving the above-mentioned problems relates to a disinfecting detergent obtained by applying ultrasonic waves to electrolyzed water to produce electrolyzed water and producing air bubbles of about 100 nanometers (claims) 1).
In the disinfectant cleaning agent of the present invention, the electrolyzed water is mainly composed of electrolyzed water on the alkaline water side (claim 2).
The disinfectant cleaning agent of the present invention is preferably stored in a container, for example, a plastic container (claim 3).
It is preferable that the disinfecting detergent of the present invention does not contain a surfactant (claim 4).

請求項１及び請求項２に記載の発明によると、界面活性剤や塩素系の除菌剤を含まず、除菌効果を有する According to the invention described in claim 1 and claim 2, it does not contain a surfactant or a chlorine-based disinfectant and has a disinfecting effect.
以下、本発明の実施形態を添付図面に基づいて行う。図１は、本発明の方法の各段階を説明するフローチャートであり、図２は、本発明の好ましい実施形態で使用する電解水調製装置を、説明するための図面であり、図３は、本発明の別の方法をの各段階を説明するフローチャートである。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a flow chart for explaining each step of the method of the present invention, FIG. 2 is a drawing for explaining an electrolyzed water preparation apparatus used in a preferred embodiment of the present invention, and FIG. 6 is a flowchart illustrating each stage of another method of the invention.
本実施形態は、電解水をナノバブル処理して得られた除菌洗浄剤である。本発明の除菌洗浄剤は、図１に示す通り、段階Ｓ１として、まず電解水を調製する。電解水の調製は、公知の方法及び装置で行うことが可能であるが、例えば、図２（ａ）〜（ｃ）に示す電解水調製装置を用いることができる。 This embodiment is a disinfecting detergent obtained by subjecting electrolyzed water to nanobubble treatment. As shown in FIG. 1, the disinfectant cleaning agent of the present invention first prepares electrolyzed water as step S1. The electrolyzed water can be prepared by a known method and apparatus. For example, an electrolyzed water preparation apparatus shown in FIGS. 2 (a) to 2 (c) can be used.
電解水は、例えば図２（ａ）に示すような装置を用いて、水を電気分解して調製するが、その際に一般に水道水を使用している。水道水は、カルシウムやマグネシウム、ナトリウム、カリウム等の金属が塩形態で含まれている電解質溶液である。 The electrolyzed water is prepared by electrolyzing water using, for example, an apparatus as shown in FIG. 2A, and tap water is generally used at that time. Tap water is an electrolyte solution containing metals such as calcium, magnesium, sodium and potassium in a salt form.
すなわち、図２（ａ）に示す通り、隔膜Ｄで仕切った水槽Ｔに仕切りの両側に各々陽極Ｅ１、陰極Ｅ２を配置し、そしてこの水槽Ｔに水道水等の電解質液を入れ、この両極Ｅ１、Ｅ２間に所定の電流を流すことによって電解水が製造される。 That is, as shown in FIG. 2 (a), an anode E1 and a cathode E2 are disposed on both sides of a partition in a water tank T partitioned by a diaphragm D, and an electrolytic solution such as tap water is placed in the water tank T. , E2 is produced by flowing a predetermined current between E2.
陽極Ｅ１側では水分子がＨ＋(水素イオン)とＯ２(酸素分子)とｅ−(電子)に分離され水素イオンが増え酸素分子が水にその際の水温における飽和濃度まで溶解する。この際に、オゾン、Ｏ２ラジカル、酸化力を有する酸化性のイオンが多く発生する。また、水中に例えば塩化ナトリウム等の電解質が存在する場合には、これらの電解質が反応を起こすことによって、各々対応する電解質由来の物質が生成される。この際には、陽極側では強酸性水が生成される。従って、陽極Ｅ１側は、酸性を呈する酸性水が調製される。 On the anode E1 side, water molecules are separated into H + (hydrogen ions), O 2 (oxygen molecules), and e − (electrons), hydrogen ions increase, and oxygen molecules dissolve in water to a saturation concentration at the water temperature. At this time, a large amount of ozone, O 2 radicals, and oxidizing ions having oxidizing power are generated. Moreover, when electrolytes, such as sodium chloride, exist in water, when these electrolytes react, the substance derived from a corresponding electrolyte is produced | generated, respectively. At this time, strongly acidic water is generated on the anode side. Accordingly, acidic water exhibiting acidity is prepared on the anode E1 side.
一方、陰極Ｅ２側では水に電子（ｅ−）が作用してＯＨ−（ヒドロキシイオン）が増加するとともにＨ２（水素分子）として水に溶解する。さらに、還元性のイオンが多く発生する陰極Ｅ２側の水の特徴として、酸素等の酸化に関与する物質が極端に減っていることである。また、カルシウム、マグネシウム、ナトリウム、カリウム等の金属の一部はイオン化して陰極Ｅ２側に引き寄せられるので、これらの金属イオンが陰極Ｅ２側の水中に溶存することも陰極Ｅ２側の水の特徴である。 On the other hand, on the cathode E2 side, electrons (e − ) act on water to increase OH − (hydroxy ions) and dissolve in water as H 2 (hydrogen molecules). Furthermore, as a feature of the water on the cathode E2 side where a large amount of reducing ions are generated, a substance involved in oxidation such as oxygen is extremely reduced. In addition, since some of the metals such as calcium, magnesium, sodium and potassium are ionized and attracted to the cathode E2 side, it is also a feature of the water on the cathode E2 side that these metal ions are dissolved in the water on the cathode E2 side. is there.
このようにして陰極Ｅ２側に溶存する金属イオンは、塩化ナトリウム、炭酸カルシウムといった対応する塩形態（元々水道水で存在する形態）と比較して非常に消化吸収されやすい状態で存在している。 In this way, the metal ions dissolved on the cathode E2 side are present in a state that is very easily digested and absorbed as compared with the corresponding salt forms (forms originally present in tap water) such as sodium chloride and calcium carbonate.
このようにして作成された電解水調製装置は、大別して２種類に分類される：
一方は水道水や純水・ミネラルウォーターなどをそのまま電解するもので、一般に「アルカリイオン水生成器」と呼ばれている装置により作製する（図２（ｂ）参照）。もう一方は、塩化ナトリウムや塩化カリウムなどの電解質を加えた水を電解するもので、一般には「強酸化水生成器」と呼ばれる装置を用いて作製する（図２（ｃ）参照）。
The electrolyzed water preparation devices thus prepared are roughly classified into two types:
One is electrolyzing tap water, pure water, mineral water or the like as it is, and is produced by a device generally called “alkaline ion water generator” (see FIG. 2B). The other is for electrolyzing water to which an electrolyte such as sodium chloride or potassium chloride is added, and is generally produced using an apparatus called a “strongly oxidized water generator” (see FIG. 2 (c)).
アルカリイオン水は、水道水を使い図２（ｂ）に示すような浄水装置２００を通してそのまま電気分解した水のマイナス側の水を使用する。
まず水道２０１から入った水は浄水器２０２に送られ、カビ臭や塩素トリハロメタンなどが取り除かれる（予備処理）。次いで、予備処理された水は、図２（ａ）に概略を示すような電極Ｅ１，Ｅ２と隔膜Ｄ（図２（ａ）参照）から構成された電解槽２０３に送られる。電解槽２０３に送られた水は、電気分解され、各々隔膜Ｄを介して陽極Ｅ１側と陰極Ｅ２側では水のｐＨが片寄りそれぞれ酸化イオン、還元イオンが含まれた２種類の水が調製される。
As the alkaline ionized water, water on the negative side of the water electrolyzed as it is through the
First, water entered from the
電解槽２０３を通過した後、前記２種類の水は別々の流路（主吐水ホース２０４、排水ホース２０５）を流れる。すなわち、マイナス側からでたアルカリイオン水は主吐水ホース２０４を通ってアルカリイオン水専用の蛇口に向け流れ、一方プラス側からでた酸性水は、排水ホース２０５へ送られ、例えばキッチンのシンク内等に廃棄される。
After passing through the
このようにして調製されアルカリイオン水は、種々の用途に有効に使用できると言われている。
本発明においては、アルカリ水を用いることが一般的であるが、酸性水やアルカリ水と酸性水のブレンドを用いることも可能である。本発明においては、イオン水を得ることが重要である。
It is said that the alkali ion water prepared in this way can be effectively used for various applications.
In the present invention, alkaline water is generally used, but acidic water or a blend of alkaline water and acidic water can also be used. In the present invention, it is important to obtain ionic water.
本発明において電解水を用いることは、必須ではないが、本発明者等による繰り返しの実験により、通常の水を後段（Ｓ２）のナノバブル工程にて気泡を形成するよりも、高い洗浄力を有することを見出した。 Although it is not essential to use electrolyzed water in the present invention, it has a higher detergency than ordinary water by forming bubbles in the nanobubble process in the subsequent stage (S2) by repeated experiments by the present inventors. I found out.
これは、水を予めイオン化することによって、より清掃能力（界面活性力）が付与されるものと考えられる。すなわち、イオン化した水を調製した後に後段のナノバブル化工程を行うことによって、発生したナノバブルをイオン類が包み込み、界面活性作用の高い清掃水が得られると考えられる。すなわち、電解水と同等のイオンを含むと期待できる電解質溶液であれば同等の効果が得られるものと考えられる。 This is considered that cleaning ability (surfactant activity) is given more by ionizing water beforehand. That is, by preparing ionized water and then performing a subsequent nanobubble generation step, it is considered that the generated nanobubbles are encapsulated by ions and cleaning water having a high surface activity can be obtained. That is, it is considered that an equivalent effect can be obtained if the electrolyte solution can be expected to contain ions equivalent to electrolyzed water.
具体的には前述の図２に示す別体で設けられた電解水調製装置で調製された電解水（又はイオン水）を処理槽に所定量（処理対象物の形状、個数等に応じて適宜決定）を導入する。 Specifically, a predetermined amount of electrolyzed water (or ionic water) prepared by the electrolyzed water preparation apparatus provided separately as shown in FIG. Introduce).
なお、本発明においては、電解水の調製に限定されるものではなく、単に水道水（又は原水）から出発してナノバブル工程を行うことも、酵素、例えば淡白分解酵素を添加した水を直接ナノバブル工程を行うことも本発明の範囲内である。 In the present invention, the invention is not limited to the preparation of electrolyzed water, and the nanobubble process may be performed simply by starting from tap water (or raw water), or by directly adding nanobubbles to an enzyme, for example, water added with a light white degrading enzyme. Performing the steps is also within the scope of the present invention.
次いで、電解水調製工程で調製された水をナノバブル工程（Ｓ２）において、処理を行う。
ナノバブルは、１００ナノメートル(1ｎm=10-９m)程度の空気泡を、超音波をかけることにより定常的に発生させる工程である（本発明においてはナノバブル処理）。
すなわち、ナノバブル発生装置（図示せず）は、超音波発生手段と気泡発生手段とから構成されており、前記処理槽中の電解水を入口側の導入管から取り込み超音波及び気泡を付与して出口側の排出管からナノバブル水として放出する手段である。
Next, the water prepared in the electrolyzed water preparation step is treated in the nanobubble step (S2).
Nanobubbles (nanobubbles process in the present invention) to 100 nanometers (1 nm = 10- 9 m) of about air bubbles, a step of generating constantly by applying ultrasound.
That is, the nanobubble generator (not shown) is composed of an ultrasonic generator and a bubble generator, and takes in the electrolyzed water in the treatment tank from an inlet pipe on the inlet side to give ultrasonic waves and bubbles. It is a means for discharging as nanobubble water from the discharge pipe on the outlet side.
ナノバブルの処理時間についても特に限定されるものではなく、数分〜数１０分、例えば約１０分程度である。また、ナノバブルの処理の際に所定温度、例えば室温〜６０℃、好ましくは室温で処理する。このようにしてナノバブルを発生した後、比較的長期間除菌効果及び洗浄効果を維持しつつ保存できることを見出した（Ｓ３）。 The processing time for nanobubbles is not particularly limited, and is from several minutes to several tens of minutes, for example, about 10 minutes. Further, the nanobubbles are treated at a predetermined temperature, for example, room temperature to 60 ° C., preferably at room temperature. Thus, after generating nanobubbles, it discovered that it could preserve | save, maintaining a bacteria elimination effect and a cleaning effect for a comparatively long period (S3).
すなわち、このようにして得られたナノバブル水に清掃対象物を浸漬すると、清掃対象物を極めて容易に清掃することが可能であることを見出して先に出願したが、このように長期間保存後、例えば３週間保存後も、その洗浄効果を失うことなく、しかも除菌作用も持続していることを見出した（後述の実施例参照）。 That is, when the object to be cleaned is immersed in the nanobubble water thus obtained, it was found that it is possible to clean the object to be cleaned very easily. For example, it was found that even after storage for 3 weeks, the sterilizing effect was maintained without losing its cleaning effect (see Examples described later).
そのため、ナノバブル水作製直後に使用できるだけでなく、例えばナノバブル水を一括して作製しておき、小分けして使用することも可能である。あるいは、容器、例えばポリエチレンテレフターレート（ＰＥＴ）、ポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）などのプラスチック容器やガラス瓶などに保存しておき、必要に応じて使用することも可能である。 Therefore, not only can it be used immediately after the production of nanobubble water, but it is also possible to produce nanobubble water in a lump and use it in small portions. Alternatively, it can be stored in a container, for example, a plastic container such as polyethylene terephthalate (PET), polypropylene (PP), or polyethylene (PE), or a glass bottle, and used as necessary.
しかも、界面活性剤等の環境に与える成分を含まなくとも十分な除菌・洗浄効果を発揮するので、処理後の処理液を排出しても環境に対する負荷が少ない。
なお、本発明における除菌・洗浄組成物は、本発明の目的、作用、効果を阻害しない範囲で他の成分、例えばタンパク分解酵素等の酵素類をふくんでもよい。
In addition, even if it does not contain components that give the environment such as surfactants, it exhibits a sufficient sterilizing and cleaning effect, so even if the treated liquid after treatment is discharged, the burden on the environment is small.
The disinfecting / cleaning composition of the present invention may contain other components, for example, enzymes such as proteolytic enzymes, as long as the purpose, action and effect of the present invention are not impaired.
（洗浄・除菌処理）
次に、本発明の除菌洗浄剤を用いた、除菌洗浄方法について説明する。
本発明の除菌洗浄剤は、洗浄対象又は、除菌及び洗浄対象の対象物（限定されるものではないが、例えば家庭用や業務用のレンジ、換気扇のフィルタ、食器類、食材（例えば野菜類等）、油が付着した冷蔵庫等の厨房機器等）に十分接触させた後に、物理的手段により拭き取り、ブラッシングなどにより対象物から汚れ、微生物を除去する方式により処理を行う。
(Cleaning and disinfection)
Next, a sterilization cleaning method using the sterilization cleaning agent of the present invention will be described.
The disinfectant cleaning agent of the present invention is an object to be cleaned or an object to be disinfected and cleaned (for example, but not limited to, a household or commercial range, a fan filter, tableware, food (for example, vegetables) Etc.), kitchen equipment such as refrigerators etc. to which oil is adhered, etc., and then, by wiping with physical means, brushing, etc. to remove dirt and microorganisms from the object.
より具体的には、対象物を本発明の除菌洗浄剤中にに浸漬する。本発明では、従来強アルカリ性の洗浄剤や高濃度の界面活性剤中に所定時間、例えば一晩浸漬しないと十分に汚れを清掃することが困難であった油性成分、例えば油、石油系成分、レジン分等が付着した対象物、多数の凹凸を有する複雑な形状の対象物や油性成分や塵埃で目詰まりをしているメッシュを有する対象物などの対象物の清掃に好適に使用することが可能である。浸漬処理する場合、また、処理時間も処理の汚れの状態等によって適宜選択されるが、例えば３年以上放置されたレンジの場合には３分から１０分程度である。このような浸漬時間は、繰り返しの実験により適宜設定することが可能である。 More specifically, the object is immersed in the disinfecting detergent of the present invention. In the present invention, oily components, such as oil, petroleum-based components, which have been difficult to clean sufficiently unless they are immersed in a strong alkaline detergent or a high concentration surfactant for a predetermined time, for example, overnight. It can be suitably used for cleaning objects such as objects with resin attached, objects with complicated shapes with many irregularities, and objects with meshes clogged with oily components and dust. Is possible. In the case of the immersion treatment, the treatment time is also appropriately selected depending on the state of dirt in the treatment, etc. For example, in the case of a range left for 3 years or longer, it is about 3 to 10 minutes. Such immersion time can be appropriately set by repeated experiments.
なお、浸漬する際のナノバブル水の温度については、特に限定されるものではないが、常温から比較的高温（例えば６０℃程度）の範囲内で処理することが可能である。温度が高温であるほど汚れの除去効果は高いが、エネルギー、装置の複雑化、対象物の耐熱性、汚れの程度などにより、適宜、水温及び処理時間を決定することが可能である。 In addition, the temperature of the nanobubble water at the time of immersion is not particularly limited, but the treatment can be performed within a range from room temperature to a relatively high temperature (for example, about 60 ° C.). The higher the temperature, the higher the effect of removing dirt, but the water temperature and treatment time can be appropriately determined according to energy, complication of the apparatus, heat resistance of the object, degree of dirt, and the like.
比較的高い温度で浸漬を行う場合には、水槽に温度制御手段又は加熱手段を設けて所定温度以上に保つことが可能である。 When immersing at a relatively high temperature, it is possible to provide a temperature control means or a heating means in the water tank to keep the temperature above a predetermined temperature.
このように浸漬することによって、ナノバブルとイオンとの作用により対象物に付着した汚れを界面活性作用により分離して、汚れを容易に除去することが可能となる。しかも、電解水の作用により処理対象物中に存在する微生物を除菌することも可能である。 By immersing in this way, it becomes possible to separate the dirt attached to the object by the action of the nanobubbles and ions by the surface-active action and easily remove the dirt. Moreover, it is possible to sterilize microorganisms present in the object to be treated by the action of the electrolyzed water.
浸漬方法の代わりに、処理対象物が比較的大きいもの、例えば厨房機器の場合には、本発明の除菌洗浄剤を噴霧等により塗布して、所定時間放置する。
この場合も、浸漬と同様にナノバブルとイオンとの作用により対象物に付着した汚れを界面活性作用により分離して、汚れを容易に除去することが可能となる。しかも、電解水の作用により処理対象物中に存在する微生物を除菌することも可能である。
Instead of the dipping method, in the case of a relatively large object to be treated, such as a kitchen device, the disinfectant cleaning agent of the present invention is applied by spraying or the like, and left for a predetermined time.
In this case as well, the dirt attached to the object by the action of the nanobubbles and ions can be separated by the surface active action as in the case of the immersion, and the dirt can be easily removed. Moreover, it is possible to sterilize microorganisms present in the object to be treated by the action of the electrolyzed water.
次いで、本発明の除菌洗浄剤に浸漬した処理対象物（又は本発明の除菌洗浄剤を塗布した処理対象物）から汚れを除去する。この際の除去手段は、特に限定されず従来公知の方法で除去を行うことが可能である。例えば、ブラッシング、布による払拭、あるいは所定の水量（水圧）の水による洗浄及びこれらの組み合わせによって浸漬した処理対象物から汚れを除去することが可能である。 Next, the dirt is removed from the processing object immersed in the sterilization cleaning agent of the present invention (or the processing object coated with the sterilization cleaning agent of the present invention). The removal means at this time is not particularly limited and can be removed by a conventionally known method. For example, it is possible to remove dirt from a processing object immersed by brushing, wiping with a cloth, washing with water of a predetermined water amount (hydraulic pressure), and a combination thereof.
汚れを除去した対象物は、対象物から十分汚れを除去できた場合、そのままあるいは後処理（仕上げ水洗等）を経て処理を完了する。
対象物から十分汚れを除去できない場合、浸漬又は塗布を繰り返した後に汚れの除去を行う。
If the object from which the dirt has been removed is sufficiently removed from the object, the process is completed as it is or after a post-treatment (such as finishing washing).
If the dirt cannot be sufficiently removed from the object, the dirt is removed after repeated dipping or coating.
このような工程で対象物から汚れを除去する本発明の方法は、多量の界面活性剤やその他の薬剤等を用いず、短期間で容易に対象物から汚れを除去できるので、薬剤等による水質の汚染を防止する対策を講じることなく、従来長時間の浸漬を要していたレンジの汚れ等を短時間で簡単に除去可能となる。 The method of the present invention for removing dirt from an object in such a process can easily remove dirt from the object in a short period of time without using a large amount of surfactant or other chemicals. Without taking measures to prevent the contamination, it is possible to easily remove the dirt and the like of the range, which conventionally required long immersion, in a short time.
以下、本発明の実施例を説明する。
電解水製造装置（ホシザキＲｏｘ−２０ＴＢ電解水装置）を用いて３０Ｌの水道水から製造した酸性水、アルカリ水を、株式会社シーズジャパン社製のＮＳ−４００超微細気泡発生装置を用いて室温℃で５分間、１００ナノメートル(1ｎm=10-９m)程度の空気泡を、超音波をかけることにより定常的に発生させて、本発明の除菌洗浄剤（アルカリ水、実施例１；酸性水、実施例２）を製造した。比較用に、アルカリ水（比較例１）、酸性水（比較例２）、水道水（比較例３）を用いて、一般細菌テスト、ＡＴＰ有機物カウント検査、ｐＨ測定及びＰＰＭ試験を行った。一般細菌テストにはサンプルをシャーレピペットで採取して日水製薬株式会社製のフードスタンプ（生菌数用標準寒天）により２４時間フラン器内で３８℃で培養して一般細菌数をカウントした。ＡＴＰ有機物カウント検査は、キッコーマン株式会社製ルミテスターＰＤ１０を用いて試薬としてルミパックワイドを用いて製造者指示に基づいて行った。ｐＨ測定は、ＭＡＲＦＩＤＥ社のＴＤＳ Ｍｅｔｅｒを用い、ＰＰＭ測定はＨ．Ｍ．Ｄｉｇｉｔａｌ社製のウォータプロ（ＷＡＴＥＲ-ＰＲＯ）を用いて行った。
Examples of the present invention will be described below.
Acidic water and alkaline water produced from 30 L of tap water using an electrolyzed water production device (Hoshizaki Rox-20TB electrolyzed water device) at room temperature using an NS-400 ultrafine bubble generator produced by Seeds Japan Co., Ltd. in 5 minutes, a 100 nm (1nm = 10- 9 m) of about air bubbles, and constantly generates by applying ultrasound, disinfectant cleaner of the present invention (alkaline water, example 1; acid Water, Example 2) was prepared. For comparison, a general bacterial test, an ATP organic matter count test, a pH measurement, and a PPM test were performed using alkaline water (Comparative Example 1), acidic water (Comparative Example 2), and tap water (Comparative Example 3). For the general bacteria test, a sample was collected with a petri dish, and cultured with a food stamp (standard agar for viable cell count) manufactured by Nissui Pharmaceutical Co., Ltd. for 24 hours in a franc vessel to count the number of general bacteria. The ATP organic matter count test was performed based on manufacturer's instructions using Lumipack Wide as a reagent using Lumitester PD10 manufactured by Kikkoman Corporation. For pH measurement, TDS Meter of MARFIDE was used, and for PPM measurement, H.D. M.M. This was carried out using a Digital Water Pro (WATER-PRO).
表１〜表４は、５種類のサンプルをそれぞれプラスチックボトルに入れ蓋なしで室温（２０〜２５℃）で保存したサンプルの結果を示し、表５〜表８は、４種類のサンプルをプラスチックボトルに入れ蓋をしめて室温（２０〜２５℃）で保存したサンプルを用いて測定の直前に開封して測定した結果を示すものである。
これらの結果から、本発明の洗浄除菌剤は、アルカリ側で強い除菌効果を有していることが判る。又、酸性側、アルカリ側ともに約３週間の保存後も同等の性能を有していることがわかる。
さらに、ＴＯＳＨテスト・ウシの血清汚染除去テストを行ったところ、実施例１及び２の洗浄剤を１５分適用後、汚染物を完全に剥離・除去できることがわかった。
Tables 1 to 4 show the results of samples in which five types of samples were put in plastic bottles and stored at room temperature (20 to 25 ° C.) without a lid, and Tables 5 to 8 show four types of samples in plastic bottles. It shows the result of opening and measuring immediately before the measurement using a sample stored at room temperature (20 to 25 ° C.) with the lid closed.
From these results, it can be seen that the cleaning disinfectant of the present invention has a strong disinfecting effect on the alkali side. It can also be seen that both the acidic and alkaline sides have equivalent performance after storage for about 3 weeks.
Furthermore, when the TOSH test bovine serum decontamination test was performed, it was found that the contaminants could be completely removed and removed after 15 minutes of application of the cleaning agents of Examples 1 and 2.
以上説明した通り、本発明は、界面活性剤等の薬剤の使用量を抑制して対象物に付着する汚れを容易に除去することが可能となる。したがって、環境負荷を軽減して対象物表面から汚れを除去することが可能となる。 As described above, according to the present invention, it is possible to easily remove the dirt adhering to the object by suppressing the amount of the agent such as a surfactant used. Therefore, it is possible to reduce environmental load and remove dirt from the surface of the object.
