Description

  The present invention relates to a bactericidal aid for electrolyzed water containing 1-menthol and / or geraniol, which are monoterpene compounds, as an active ingredient, and an electrolyzed water composition containing electrolyzed water, glycerin fatty acid ester and monoterpene compound.

  It is known that electrolyzed water obtained by electrolyzing water containing an electrolyte and having an electrochemical reaction has sterilizing power (see, for example, Non-Patent Document 1 and Patent Document 1). In particular, some electrolyzed water obtained by electrolyzing water containing dilute hydrochloric acid as an electrolyte is approved as a food additive having a bactericidal action. Such electrolyzed water is used in the field of food engineering for sterilization, washing, maintaining the freshness of food, and the like. Application to the medical field as a safe and low-cost sterilizing cleaning agent is also being sought.

  In order to further enhance the cleaning effect of the electrolyzed water, it is conceivable to add a surfactant to obtain a composition having high wettability and a cleaning function in addition to the bactericidal action of the electrolyzed water. In particular, it is considered that a composition safe for the human body can be obtained by adding a surfactant recognized as a food additive to electrolyzed water.

However, the bactericidal effect of electrolyzed water is due to the property of hypochlorous acid that oxidizes sites with high electron density such as C = C bond, C = N bond, C—N bond, —NH 2 group, and —SH group. It is. It is known that when a surfactant is added to hypochlorite, the hypochlorite and the surfactant are decomposed and lost due to oxidation (see, for example, Patent Documents 2 and 3).

JP 2003-10852 A Japanese Patent Laid-Open No. 4-135559 JP 9-31494 A Masao Matsuo, "Basic and Utilization Technology of Electrolyzed Water", Gihodo Publishing Co., Ltd., January 25, 2000

It is possible to provide an electrolyzed water composition that is safe and safe and has a sustained bactericidal action.

  Hereinafter, the best mode for carrying out the present invention will be described. In addition, this invention is not limited to the form demonstrated below at all, In the range which does not deviate from the summary, it can implement with a various aspect. In the present specification, the percentage is expressed by mass unless otherwise specified. Moreover, the indication of parts per million (ppm) is a value meaning μg / ml unless otherwise specified.

  In the present invention, electrolyzed water is a liquid obtained by electrolyzing raw material water containing an electrolyte. More preferably, it is electrolyzed water that is slightly acidic (hereinafter referred to as “slightly acidic electrolyzed water”). As such a slightly acidic electrolyzed water, an electrolyzed water having a sodium ion concentration of 200 ppm or less, more preferably 50 ppm or less, which is a water quality standard of waterworks, and a pH of 4.5 to 6.8 is used. Among them, it is particularly preferable that the effective chlorine concentration is 10 to 30 ppm and the pH is 5.0 to 6.5.

In the present invention, “effective chlorine” means a group of chlorinated chemical species having a bactericidal disinfection action. The available chlorine is "free chlorine [HOCl (hypochlorous acid) + CLOs - (hypochlorite) + Cl 2 (aq) (dissolved chlorine)]" by the sum of the "combined chlorine (chloramines etc.)" Indicated. Therefore, the measurement of the effective chlorine concentration is obtained by the sum of the free chlorine concentration and the combined chlorine concentration. However, in the conventional practice, combined chlorine is often handled separately, and only free chlorine is often referred to as effective chlorine (residual chlorine). Therefore, the term “free chlorine” is defined as “effective chlorine”. Is also possible ("Basic and Utilization Technology of Electrolyzed Water", Gihodo Publishing Co., Ltd., first edition, first printing, published on January 25, 2000, pages 23-25). In addition, the effective chlorine concentration measured in the Example etc. of this invention is measured as a free chlorine concentration, and can be measured by the neutralization titration method using methyl orange etc. as an indicator.

  The electrolyzed water is generally generated by adding sodium chloride in order to increase electrolysis efficiency. However, even in that case, in the present invention, it is preferable to use slightly acidic electrolyzed water having a sodium ion concentration of 200 ppm or less as described above. Moreover, even if sprayed, the crystals of sodium chloride do not remain, which is highly convenient.

  This is because it can be said that such slightly acidic electrolyzed water does not substantially contain sodium chloride, so that even if it remains after use, it is considered that there is no influence on the flavor of food.

  Such slightly acidic electrolyzed water can be produced by the following procedure. That is, first, hydrochloric acid is added to water that does not substantially contain sodium chloride. Here, “water” means tap water, ground water, underground water, demineralized water, distilled water, purified water (RO water, membrane treated water), or a mixed water thereof. It means water that does not contain.

  Here, the meaning of “substantially no sodium chloride” means that sodium chloride is not artificially added. In this case, a trace amount of sodium chloride naturally contained in water is not considered. The fact that sodium chloride has not been artificially added means that the sodium ion concentration of water to which hydrochloric acid has been added does not exceed the sodium ion concentration contained in the “water”. For example, since such “water” generally has a sodium ion concentration of 200 ppm or less, the sodium ion concentration of the water added with hydrochloric acid in the present invention is preferably 200 ppm or less.

  Moreover, when using natural water and tap water, such as groundwater and underground water, it is preferable that the density | concentration of a total organic carbon is 2 ppm or less. Moreover, it is preferable that total hardness is 50-100 mg / L.

  In addition, the hydrogen chloride concentration in the case of adding hydrochloric acid to water is preferably 0.01% or more, and particularly recommended to be 0.1% or more in order to cause an appropriate reaction. However, from an economical viewpoint, the hydrogen chloride concentration is preferably 1.0% or more and 21.0% or less. That is, if the hydrogen chloride concentration is 1.0% or more, an industrially stable reaction can be obtained, and if it is 21.0% or less, no smoke is generated at room temperature, and storage and handling are possible. This is because there is no particular difficulty.

  After passing such water added with hydrochloric acid through the diaphragm electrolyzer, the negative and positive electrodes are energized and electrolyzed to obtain electrolyzed water. Here, the non-diaphragm electrolytic cell is an electrolytic cell having no diaphragm. The non-diaphragm electrolytic cell may be a monopolar electrolytic cell, but is preferably a bipolar electrolytic cell. In general, two types of methods of connecting a plurality of electrodes in an electrolytic cell are known: a monopolar type and a bipolar type. The monopolar type is a system in which all of the electrodes are connected to either the cathode or the anode of the power supply, and the multipolar type has, for example, a structure in which a plurality of electrodes are stacked at a predetermined interval and insulated from each other. In addition, there is at least one intermediate electrode that is not connected to any electrode between the electrode connected to the anode of the power source (ie, the anode) and the electrode connected to the cathode of the power source (ie, the cathode). It is a method.

  In the electrolysis, the voltage per pair of electrodes is preferably 1.5 volts or more and 4.0 volts or less. In the case of a bipolar electrolytic cell, an intermediate electrode exists between the cathode and the anode as described above, but the “voltage per pair of electrodes” includes the cathode, the anode, and the intermediate electrode. , A term meaning the voltage between two adjacent electrodes.

  In general, it is known that when the voltage per pair of electrodes is increased, chlorine starts to be generated at 1.3 volts or more and reaches the maximum generation amount at 1.5 volts or more. Therefore, it can be said that the voltage per pair of electrodes is preferably 1.5 volts or more. It is also known that oxygen starts to be generated when the voltage exceeds 4.0 volts, and ozone starts to be generated when the voltage exceeds 5.0 volts. Since generation of ozone is not preferable from the viewpoint of the working environment, the voltage is preferably 5.0 volts or less. Moreover, since the generation of oxygen is a waste of electric power, the voltage is particularly preferably 4.0 volts or less. The voltage is preferably 3.0 volts or less from an economic viewpoint. At least, since generation of ozone is not preferable as described above, the voltage is preferably 5.0 volts or less, and the electrolyzed water used in the present invention is particularly preferably electrolyzed water without ozone.

After producing electrolyzed water in this way, the produced electrolyzed water may be diluted. In general, in the production of electrolyzed water, it is preferable in terms of economy to electrolyze water having a high chlorine concentration to produce a small amount of electrolyzed water and then dilute and use it. Therefore, after electrolysis, it is preferable to collect electrolyzed water after dilution. The degree of dilution is preferably such that the pH is in the range of 5.0 to 6.5 and the effective chlorine concentration is in the range of 10 to 30 ppm.
The electrolyzed water thus produced does not lose its bactericidal effect even if the effective chlorine concentration is diluted to a concentration of 1 to 2 ppm.

  Electrolyzed water may be neutralized with a neutralizing agent. When electrolyzed water having a high effective chlorine concentration is obtained, the pH of the electrolyzed water may be lowered. In general, it is known that the sterilizing power of water in which chlorine is dissolved varies depending on the pH ( Published by Fuji Techno System Co., Ltd., “Food Industry Microbial Control Technology Collection,” pages 242-243, 1977). According to this, since the bactericidal power will become high if the pH of electrolyzed water is 4.5-6.8, it is preferable to become the pH range.

  Moreover, if electrolyzed water is strong acidity, it will receive restrictions on the place to use, a method, etc., Therefore It is preferable that the pH of electrolyzed water is 5.0 or more. As such a neutralizing agent, an alkaline chemical is suitable, and sodium hydroxide, potassium hydroxide, sodium bicarbonate, sodium carbonate and the like can be used, and sodium hydroxide is most preferred. When the electrolyzed water is neutralized in this way, the neutralizing agent may be added before or after dilution, but the latter is preferable.

  The electrolyzed water described above can be produced by, for example, Purestar (registered trademark), which is an electrolyzed water production apparatus manufactured by Towa Techno Co., Ltd. In this apparatus, a tank storing 21% hydrochloric acid or 3% hydrochloric acid is installed. In the former case, 21% hydrochloric acid is diluted with water and then passed through a diaphragm electrolyzer. In the latter case, 3% hydrochloric acid itself is “water to which hydrochloric acid has been added”. Pass water through the diaphragm electrolyzer. And it is possible to electrolyze continuously and to produce electrolyzed water. In this case, the condition is such that the obtained electrolyzed water has a pH of 4.0 or more, preferably pH 4.5 to 6.8, particularly preferably pH 5.0 to 6.5, and an effective chlorine concentration of 10 to 30 ppm. Therefore, it is preferable to adjust the electrolysis conditions of the diaphragm membrane electrolytic cell and dilute the electrolyzed water.

  The electrolyzed water produced in this way has substantially no sodium chloride added, and has a pH that is almost neutral, and has properties close to natural water as compared to normal electrolyzed water. is doing. Therefore, it is suitable for producing the electrolyzed water composition according to the present invention.

  As one embodiment of the present invention, a sterilization aid for electrolyzed water containing l-menthol and / or geraniol as an active ingredient is provided. Examples of the sterilization auxiliary agent according to one embodiment of the first invention of the present application include those used for inhibiting decomposition of electrolyzed water or reducing reduction of effective chlorine concentration in electrolyzed water, and maintaining the sterilizing effect of electrolyzed water. Drugs used for the purpose are provided. “A and / or B” means either or both of A and B.

  1-menthol and / or geraniol, which is an active ingredient of a sterilization auxiliary for electrolyzed water according to an embodiment of the present invention, is a monoterpene compound having fragrance and is generally used as a fragrance. is there. That is, the active ingredient in the sterilization aid for electrolyzed water according to one embodiment of the present invention is particularly preferably l-menthol and / or geraniol, but other monoterpenes as long as the same effect is maintained. It goes without saying that compounds can be used.

  Other monoterpene compounds include linalool, myrcene, osimene, cosmene, nerol, citronellol, myrsenol, lavandulol, ipsdienol, perylene, rosefuran, limonene, thymol, chrysanthemol, grangesol, junionone, thioterpineol. , Iridoid, sequoidoid, menthane, limonene, ferrandolene, terpinolene, terpinene, cymen, pregol, piperitol, terpineol, carveol, thymol, anethole, dihydrocarbeol, menthone, plegon, ferrandral, piperidone, eucalyptol, ascaridol , 3-carene, tsugen, tsujon, tuzanol, pinene, borneol, higher fatty acid alkanolamide, higher fatty acid alkanol And nonionic active agent ethylene adducts of an amide are exemplified.

  In one embodiment of the present invention, it is preferable to use a monoterpene compound containing l-menthol and / or geraniol that satisfies the specifications as a food additive. This monoterpene compound is used after appropriately diluted with ethanol or water. When ethanol is used, it is preferable to use the minimum amount of ethanol that can disperse such substances.

  Moreover, the monoterpene compound containing 1-menthol and / or geraniol used for the disinfection adjuvant of electrolyzed water can be suitably determined according to use conditions and a use purpose. Among them, in consideration of the type of electrolyzed water, the degree of scent when sprayed, the economy, etc., it can be appropriately set in a concentration range of 1 to 500 ppm and contained in the sterilization aid, but in particular at 10 to 50 ppm. Most preferably it is used.

  On the other hand, in one embodiment of the present invention, the electrolyzed water to which the sterilization auxiliary agent is applied may be composed only of electrolyzed water or may be electrolyzed water containing a surfactant. A variety of surfactants can be used. Among them, a polyglycerin fatty acid ester recognized as a food additive is preferable. When selecting a polyglycerin fatty acid ester, it is preferable to select a polyglycerin fatty acid ester having 14 or less carbon atoms in the fatty acid moiety, with 8 to 14 being particularly preferred. When the inventor of the present application conducted a preliminary experiment, the slightly acidic electrolyzed water tends to be decomposed as the number of carbon atoms in the fatty acid portion increases.

  In addition, when the carbon number of the fatty acid part is 8, the inventor of the present application has a deglycerin monocaprylic acid in which the monoester content of the polyglycerol fatty acid ester is 80% or more and the degree of glycerol polymerization is 10 or more. The conclusion was reached that an ester is preferred.

  The amount of the above-described polyglycerin fatty acid ester added to the electrolyzed water as a surfactant is arbitrary. However, since it is known that when the concentration after addition is lower than 250 ppm, the action as a surfactant is reduced, the lower limit of the concentration after addition is preferably 250 ppm. Further, since it cannot be said that the cleaning action is infinitely increased even if the concentration is increased, the upper limit of the concentration after the addition can be set to 5000 ppm, for example.

  Moreover, as one embodiment of this invention, the above-mentioned sodium ion concentration is 200 ppm or less, pH is 4.5-6.8, and the effective chlorine concentration is 10-30 ppm, Electrolyzed water characterized by the above-mentioned There is provided an electrolyzed water composition comprising a glycerin fatty acid ester of the above and a monoterpene compound as described above. Here, the embodiment in the electrolyzed water, the glycerin fatty acid ester, and the monoterpene compound contained in the electrolyzed water composition is the same as the sterilization aid for electrolyzed water according to one embodiment of the present invention described above.

  The electrolyzed water composition according to an embodiment of the present invention has an effect that the bactericidal effect in electrolyzed water lasts for a long period of time. Moreover, it has the effect of having the washing | cleaning effect by the glycerol fatty acid ester which is surfactant, and the aromaticity by the monoterpene compound which is a fragrance | flavor. It is also safe for the human body. Therefore, the electrolyzed water composition according to one embodiment of the present invention is a disinfectant for sterilization and cleaning in manufacturing sites such as food factories and stores that handle food and drink, sterilization for workers and patients in medical settings, etc. It can be safely used as a cleaning agent.

  In order to store the electrolyzed water composition according to one embodiment of the present invention, it is preferable to fill a container formed of a material having gas barrier properties. For example, tanks and bottles having a sealable lid with a capacity of 1 L to 20 L, and 500 ml to 1000 ml spray bottles having a trigger function are desirable. In addition, after filling the container with the electrolyzed water composition according to the present invention and sealing the container, the container can be stored at room temperature under light shielding in order to suppress decomposition of the electrolyzed water. It is preferable to store in

  Furthermore, this invention also exists in the preservation | save method of the composition which adds a monoterpene compound to the composition containing electrolyzed water and surfactant, and preserve | saves the said composition.

  Hereinafter, examples of one embodiment of the present invention will be described. Specifically, the reduction inhibitory effect of the effective chlorine concentration in the electrolyzed water by 1-menthol and / or geraniol was confirmed.

(1) Preparation of sample l-Menthol (manufactured by Wako Pure Chemical Industries, Ltd.) was dissolved in a 55% aqueous ethanol solution to a concentration of 1% to obtain a l-menthol sample solution.

  Geraniol (manufactured by Wako Pure Chemical Industries, Ltd.) was dissolved in a 55% aqueous ethanol solution to a concentration of 1% to obtain a geraniol sample solution.

  As electrolyzed water, pure starmate 3 (3% dilute hydrochloric acid) sold by Morinaga Engineering Co., Ltd. is used, and Purestar (registered trademark) MP-240 (240 L / hour slightly acidic electrolyzed water manufactured by Towa Techno Co., Ltd.) is used. In a device that can be produced, slightly acidic electrolyzed water having an effective chlorine concentration of 30 to 33 ppm and a pH of 5.0 was used.

  As the surfactant, MCA-750 (decaglycerin monocaprylate), a product of Sakamoto Pharmaceutical Co., Ltd., dissolved in distilled water so as to be 10% by weight was used.

(2) Test method Prepare 14 trigger bottles with 500 ml capacity of light-shielding and gas barrier properties, put 400 ml of the slightly acidic electrolyzed water and 2 ml of the surfactant in each, and in 7 as the first test section 2 ml of the l-menthol sample solution was added, and 2 ml of the geraniol sample solution was added to the remaining seven as the second test section, and each was mixed well.

  Further, as the control group, the above-mentioned seven trigger bottles were prepared separately, and 400 ml of the slightly acidic electrolyzed water and 2 ml of the surfactant were put in each of them and mixed well.

  The trigger bottle containing each sample is stored at room temperature for a maximum of 7 months, 2 weeks, 1 month, 2 months, 3 months, 4 months, 5 months, 7 months after the start of storage. One month after opening from each section, the effective chlorine concentration and pH were measured.

  The effective chlorine concentration is measured by taking 70.9 ml of liquid from each test area in a beaker and adding 2 ml or more of 3% hydrochloric acid to adjust the pH, and then 0.1 w / v% methyl orange (Wako Pure Chemical Industries, Ltd.) (Manufactured by the company) and measured by neutralization titration.

  Moreover, pH was measured by the glass electrode method using D-51 (pH meter) by Horiba Ltd.

(3) Test results FIG. 1 shows changes in the effective chlorine concentration in each test group and control group. As shown in FIG. 1, the effective chlorine concentration of the slightly acidic electrolyzed water containing the surfactant is maintained for a long period of 4 to 5 months from the start of storage in the test section to which l-menthol or geraniol is added. It was confirmed that

  On the other hand, in the control group containing no l-menthol or geraniol, the effective chlorine concentration became 0 almost two months after the start of storage, and it became clear that the bactericidal effect of slightly acidic electrolyzed water disappeared.

  FIG. 2 shows changes in pH in each test group and control group. According to FIG. 2, in the control group, the pH decreased from the start of storage to 2 months, and thereafter showed a constant pH, whereas in the test group, the pH was increased from the start of storage to 7 months after the end of the test period. Was confirmed to be an almost constant and gradual downward trend.

  FIG. 3 shows a graph of the abundance ratio of hypochlorous acid in water against pH. According to FIG. 3, when the pH is in the vicinity of 3.5, the abundance ratio of hypochlorous acid decreases as the pH decreases. Therefore, FIG. 2 and FIG. 3 confirmed that the abundance ratio of hypochlorous acid in water was higher and the bactericidal effect was higher in the test group than in the control group.

  In addition, this inventor added 1-menthol or geraniol to the above-mentioned slightly acidic electrolyzed water without using a surfactant and observed changes in effective chlorine concentration and pH. Similar changes were observed when added. Therefore, it was confirmed that monoterpene compounds such as l-menthol and geraniol have a function of suppressing the decomposition of slightly acidic electrolyzed water and maintaining the bactericidal effect.

  Hereinafter, reference examples and results obtained for confirming the bactericidal effect and cleaning effect of the electrolyzed water composition according to the present invention will be described.

It has been found that the bactericidal effect is high even when compared with simple purified water or purified water containing 250 ppm or 500 ppm of polyglycerol fatty acid ester.

[Reference Test Example 2]
In this reference test, in order to confirm the cleaning effect of the electrolyzed water composition according to the present invention, the test was performed in order to confirm the cleaning effect of the composition obtained by adding a surfactant to electrolyzed water.

(Preparation of reference sample for cleaning effect)
Among the compositions used in Reference Test Example 1, a composition containing 500 ppm of decaglycerin dicaprylate having 8 carbon atoms was used as a reference test sample. Moreover, the slightly acidic electrolyzed water which does not add surfactant was used as the reference control sample.

(Preparation of reference specimen for cleaning effect)
First, a model soil solution was prepared based on the formulation shown in Table 3. That is, 20 g of fat and oil mixed with beef tallow: soybean oil in a ratio of 1 ml: 1 ml, 0.25 g of monoolein, and 0.1 g of oil red were dissolved in 60 ml of chloroform to prepare a model soil solution.

  The slide glass was immersed in this model soil solution for 2 seconds, pulled up to remove excess water droplets, then air-dried for 2 hours, and this was used as a carrier. The mass of the carrier was measured, and the value obtained by subtracting the mass of the slide glass that had been measured in advance was defined as “mass of attached dirt before cleaning”.

(Reference test method for cleaning effect)
In two 1 liter beakers, 700 ml (reference setting at 40 ° C.) of each of the reference test sample and the reference control sample are put, and stirred with a stirrer at 1000 ± 20 rpm. The carrier (slide glass) is set here, and 15 After a minute, it was lifted and subsequently immersed in 700 ml of purified water for 30 seconds. After pulling up, draining water, and air-drying overnight, the mass of the carrier was measured, and the value obtained by subtracting the mass of the slide glass that had been measured in advance was defined as “mass of attached dirt after washing”.

Based on the above measurement results, the cleaning rate was determined by the following equation.
Cleaning rate (%) = (mass of adhered dirt before washing-mass of adhered dirt after washing)
/ Mass of attached dirt before washing x 100

(Reference test result of cleaning effect)
The results of this reference test are as shown in Table 4.

  From Table 4, the reference test sample has a cleaning rate of 8.7%, whereas the reference control sample has a cleaning rate of 5.8%, and the reference test sample has a cleaning rate of about 1.5 compared to the reference control sample. It is clear that it is twice as high. As a result of this reference test, it was confirmed that the electrolyzed water composition according to the present invention has a higher cleaning effect than ordinary slightly acidic electrolyzed water.

  The sterilization aid, electrolyzed water composition, etc. according to the present invention can improve the cleaning effect and aromaticity without deteriorating the sterilizing effect of electrolyzed water, and can maintain the effect for a longer period of time. . Since the surfactant and flavor added to the electrolyzed water are food additives, they can be safely used for workers in food production sites, workers in medical sites, patients, and the like.

It is a graph which shows the time change of effective chlorine concentration. It is a graph which shows the time change of pH. It is a figure which shows the abundance ratio in the water of hypochlorous acid with respect to pH.
