Technical field

The present invention relates to an ozone-dissolved glycerin solution, an ozone-dissolved glycerin solid, an ozone-dissolved mixed solution, a method for producing an ozone-dissolved glycerin solution, a method for producing an ozone-dissolved mixed solution, and a method for storing an ozone-dissolved glycerin solution.

Background art

[0002] Various studies have demonstrated that ozone has a strong iridescent effect and is useful for sterilization. As a general method for producing gaseous ozone, there is a method of discharging a part of air to ozone.

[0003] In addition to gaseous ozone, ozone water in which ozone is dissolved in water is also used.

The method of producing ozone water includes dissolving ozone produced by discharging air into water by some method, and oxygen generated by directly electrolyzing water using an electrode having an ozone generation catalytic function such as platinum. Some parts are ozone-ridden and immediately dissolved in water

[0004] In addition, a gas containing ozone at a concentration 0. 01- 500 ppm generated in an ozone generator, ozone inclusion of this viscosity was encapsulated by dissolving or micro-bubbles into the liquid 1 one 10 ⁶ Pa · s A viscous body is known. Since gaseous ozone and ozone water do not have fixability, the ozone encapsulating viscous material, which had limited use, can fix it as a cream or paste on a specific site and cause ozone to act (see Patent Document 1). ).

Patent Document 1: Japanese Patent Application Laid-Open No. 10-139645

Disclosure of the invention

Problems to be solved by the invention

[0005] By the way, at the wound site where the ozone-enclosed viscous material is actually used as a disinfectant, a large number of oxides (organic substances, blood, etc.) using ozone are present, so that a high concentration of ozone is dissolved. Ozone concentration of about 80 ppm in final concentration is required. However, in the above SL ozone inclusion viscosity稠体of a gas containing ozone at a concentration 0. 01- 500 ppm, the viscosity is sealed by dissolving or micro-bubbles into the liquid 1 one 10 ⁶ Pa 's, ozone end of The concentration was extremely low and was not suitable for practical use.

[0006] In addition, when the ozone concentration immediately after the production of the ozone-enclosed viscous body is low, the ozone concentration decreases when the storage period is prolonged, and the sterilization effect cannot be maintained. In addition, depending on the type of viscous material, it may be oxidized by ozone to produce harmful oxides (peroxides).

[0007] An object of the present invention is to maintain an ozone concentration sufficient for exhibiting a bactericidal effect and a wound healing effect for a long period of time, and to produce ozone-dissolved glycerol that does not generate harmful oxidants. The present invention provides a method for producing an ozone-dissolved glycerin solution, a method for producing an ozone-dissolved mixed solution, a method for producing an ozone-dissolved mixed solution, and a method for storing an ozone-dissolved glycerin solution.

Means for solving the problem

[0008] In order to solve the above problems, the invention described in claim 1 is an ozone-dissolved glycerin solution, wherein at least 400 ppm of ozone is dissolved in a 75 wt% or more non-oxidized glycerin solution. It is characterized by

[0009] According to the invention set forth in claim 1, ozone is dissolved at a high concentration in the non-oxidizing glycerin at a high concentration, so that an ozone concentration sufficient to exhibit a bactericidal effect is obtained. It can be kept for a long time.

[0010] The invention described in claim 2 is an ozone-dissolved mixed solution, wherein an ozone-dissolved glycerin solution having an ozone power of OO ppm or more dissolved in a non-oxidized glycerin solution of 75 wt% or more is treated with water. Ozone is dissolved in at least 80 ppm by mixing with any one of petroleum, petrolatum, and polyethylene glycol.

[0011] The high concentration of glycerin is irritating to the skin, and therefore, when used in a lotion or a serum, it is necessary to reduce the concentration of glycerin. According to the invention, the irritation of glycerin can be suppressed by mixing the ozone-dissolved glycerin solution with one of water, vaseline, and polyethylene glycol. In addition, ozone Since Oppm or more is dissolved, sufficient sterilization ability can be exhibited.

[0012] When glycerin is added to ozone water after dissolving ozone in water, the oxidizing power rapidly disappears depending on the glycerin concentration. The oxidizing power is not lost even when the dissolved glycerin solution is diluted with water.

[0013] In addition, when vaseline or polyethylene glycol is brought into gas-liquid contact with high-concentration ozone, a high concentration of glycerin is dissolved in high-concentration glycerin, which causes harmful oxidization (peroxidation). When mixed with petrolatum or polyethylene glycol after having been allowed to exist, no harmful oxides (peroxides) are generated. Therefore, by mixing any one of water, petrolatum, and polyethylene glycol with the ozone-dissolved glycerin solution and stirring the mixture, the oxidizing power is not lost and no harmful oxides (peroxides) are contained. An ozone-dissolved mixed solution can be produced.

[0014] The invention described in claim 3 is a method for producing an ozone-dissolved glycerin solution.

A gas containing ozone is brought into gas-liquid contact with a glycerin solution of 75% by weight or more to dissolve ozone of 400 ppm or more.

[0015] According to the invention set forth in claim 3, ozone is dissolved in high-concentration glycerin at a high concentration by bringing a gas containing ozone into gas-liquid contact with a glycerin solution of 75 wt% or more. An ozone-dissolved glycerin solution can be produced.

[0016] The invention described in claim 4 is a method for producing an ozone-dissolved mixed solution, wherein a gas containing ozone is brought into gas-liquid contact with a glycerin solution of 75 wt% or more to dissolve 400 ppm or more of ozone. It is characterized in that ozone is dissolved by 80 ppm or more by mixing and stirring with any one of water, petrolatum and polyethylene glycol.

[0017] According to the invention set forth in claim 4, it is possible to obtain the same effect as the invention set forth in claim 2.

[0018] The invention described in claim 5 is a method for storing an ozone-dissolved glycerin solution.

The ozone-dissolved glycerin solution in which ozone is dissolved in the non-oxidizing glycerin solution is stored refrigerated or frozen.

[0019] Here, refrigerated storage is to store at 5 ° C or more and 10 ° C or less, and frozen storage is

Store at 5 ° C or less. The glycerin concentration of the ozone-dissolved glycerin solution and The ozone concentration is arbitrary.

[0020] According to the invention set forth in claim 5, the ozone-dissolved glycerin solution in which ozone is dissolved in the non-oxidizing glycerin solution is stored at room temperature by refrigeration or freezing. Can also maintain the ozone concentration at a high concentration for a long time.

The invention described in claim 6 is an ozone-dissolved glycerin solidified product, wherein ozone is dissolved in a non-oxidizing glycerin solution, and the ozone-dissolved glycerin solution is cooled and solidified. It is characterized by having.

Here, the solidified ozone-dissolved glycerin is an ozone-dissolved glycerin solution in a cooled and solidified state, and glycerin may be crystallized and solidified, or may be supercooled and become viscous in the entire solution. May be high and solidified. Further, glycerin may be solidified alone, or may be solidified together with other components constituting the solution. The glycerin concentration and ozone concentration of the ozone-dissolved glycerin solution are arbitrary.

[0023] According to the invention set forth in claim 6, ozone is dissolved in the non-oxidized glycerin solution, and the ozone-dissolved glycerin solution is cooled and solidified. It is possible to maintain a high concentration of ozone for a longer period of time, because ozone is not easily released. The invention's effect

According to the present invention, high concentration ozone is dissolved in high concentration glycerin solution.

In addition, the dissolved concentration of ozone in the ozone-dissolved glycerin solution can be maintained for a long time at a concentration sufficient for use as a disinfectant or the like.

[0025] Further, since the ozone-dissolved glycerin solution is mixed with any of water, vaseline, and polyethylene glycol, the ozone-dissolving power is not lost, and a harmful odonide (peroxydani) is included. No ozone-dissolved mixed solution can be produced.

[0026] Further, by storing the ozone-dissolved glycerin solution in a refrigerated or frozen state, the ozone concentration can be maintained at a high level for a long period of time as compared with the case of storing it at room temperature. Further, by cooling and solidifying the ozone-dissolved glycerin solution, ozone is released from the liquid state, and the ozone concentration can be maintained at a high level for a longer period of time.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail. Ozone dissolved glycer of the present invention A phosphorus solution can be produced by bringing a high-concentration glycerin solution and a high-ozone-concentration gas into gas-liquid contact.

[0028] A gas having a high ozone concentration can be produced by, for example, an ozone generator that generates ozone by silently discharging oxygen gas. When oxygen gas is used, a medical oxygen cylinder may be used, or oxygen gas produced by an oxygen generator may be used. With air, nitrogen oxides are produced. When a gas with a high ozone concentration is generated using air and the ozone concentration is measured by the potassium iodide titration method, the apparent consumption of potassium iodide increases, but this is due to nitrogen oxide. Since nitrogen oxides are harmful substances, the method using air is not suitable for actual use.

[0029] As the high-concentration glycerin solution, a glycerin solution having a glycerin concentration of 75% by weight or more can be used. A glycerin concentration of 84 to 87% by weight of the Japanese Pharmacopoeia is preferred. It is more preferred to use concentrated glycerin of at least%. Further, it is more preferable to use purified glycerin having a concentration of 98.5 wt% or more. This is because if the glycerin concentration is high, ozone can be dissolved at a higher concentration.

[0030] As a method of bringing a high-concentration glycerin solution into contact with a gas having a high ozone concentration and a gas, for example, a high-concentration (for example, 98 wt% or more) glycerin solution is put into a tank, and the tank is filled with a diffuser tube. There is a method of discharging a gas having a high ozone concentration as fine bubbles. For example, an ozone-dissolved glycerin solution having an ozone concentration of about 3000 ppm can be produced by aerating a gas having an ozone concentration of 80 gZkL (about 37,000 ppm) in concentrated glycerin for about 7 days.

[0031] The final concentration of ozone is determined depending on the glycerin concentration. In the case of the above-described method, the final concentration of ozone is approximately 400 ppm at a glycerin concentration of 75 wt%, and the final concentration of ozone is approximately 500 ppm at a glycerin concentration of 85 wt%. At 90 wt%, the final concentration of ozone is about 100 ppm, and at 98 wt% of glycerin, the final concentration of ozone is about 3000 ppm.

[0032] The finally obtained ozone-dissolved glycerin solution preferably has a glycerin concentration of 75 wt% or more and an ozone concentration of 400 ppm or more, more preferably a glycerin concentration of 80 wt% or more and an ozone concentration of 500 ppm or more. More preferably, the ozone concentration is 10 OOppm or more when the glycerin concentration is 90 wt% or more.The ozone concentration is 30 when the glycerin concentration is 98 wt% or more. Most preferably, it is at least OO ppm. The higher the concentration of glycerin, the higher the concentration of ozone, the higher the bactericidal and wound healing effects, and the ability to maintain the ozone concentration over a long period of time. The ozone-dissolved glycerin solution produced in this way has a high initial concentration of ozone, has a long half-life of ozone concentration as described later, and maintains the ozone concentration required as a disinfectant for a long period of time. You can do it.

[0033] Further, as is evident from the long half-life of the ozone concentration, the amount of ozone released from the ozone-dissolved glycerin solution is extremely small. Therefore, ozone can be gradually released over a long period of time at the use site and the arrival site of the ozone-dissolved glycerin solution. Further, since the amount of released ozone is extremely small, this ozone-dissolved glycerin solution does not have an ozone smell at all even though a high concentration of ozone is dissolved.

[0034] The ozone-dissolved glycerin solution is refrigerated at 5 ° C to 10 ° C or frozen at 5 ° C or less to further reduce the amount of ozone released. Therefore, the ozone concentration can be maintained at a high level for a longer period of time than when stored at room temperature.

[0035] In particular, when the ozone-dissolved glycerin solution is cooled to be a solidified ozone-dissolved glycerin solution, it is possible to maintain the ozone concentration at which ozone is released more easily than in the liquid state, for a longer period of time. . Here, the solidified ozone-dissolved glycerin is an ozone-dissolved glycerin solution in a cooled and solidified state, and the glycerin may be crystallized and solidified, or may become a supercooled state and the viscosity of the entire solution may increase. You may. In addition, glycerin may be solidified alone or may be solidified together with other components constituting the solution.

[0036] Here, not only ozone-dissolved glycerin solutions having a glycerin concentration of 75 wt% or more and an ozone concentration of 400 ppm or more, but also ozone-dissolved glycerin solutions of any concentration can be stored in a refrigerator or frozen for a longer period of time. , Can be maintained at a high concentration. The same applies to the case where it is cooled to obtain a solid ozone-dissolved glycerin.

[0037] Since it is assumed that glycerin is oxidized by dissolving ozone in concentrated glycerin, this time, the ¹ H-NMR spectrum and ¹³ C-NMR ^ of the raw material glycerin and the ozone-dissolved glycerin solution were used. The vectors were measured and compared. As a result, the spectrum of the raw material glycerin Oxide of glycerin was not detected, which is the same as that of the spectrum of the ozone-dissolved glycerin solution. Therefore, it was evident that glycerin was not oxidized by ozone even when high concentration ozone was dissolved in concentrated glycerin.

[0038] Although the natural half-life of gaseous ozone is about 2 hours, the half-life of ozone in an ozone-dissolved glycerin solution was much longer as described later. . Therefore, it is presumed that ozone in the ozone-dissolved glycerin solution is dissolved in glycerin, not in the form of bubbles. Immediately after actually producing the ozone-dissolved glycerin solution, if many air bubbles are left for a few hours to allow the naked eye to observe them, these air bubbles will not be observed.

[0039] The ozone-dissolved glycerin solution can be used as it is depending on the application. However, when used in a lotion or a serum, the high concentration of glycerin is irritating to the skin. Preferably, the concentration is 20 wt% or less. For this reason, it is preferable to dilute the ozone-dissolved glycerin solution by mixing it with an appropriate diluent.

[0040] As such a diluent, those which are not easily rancid by ozone are suitable, and water, petrolatum, polyethylene glycol and the like are suitable. When water is used as the diluent, it is preferable to use pure water or ultrapure water. If water contains impurities, it can be oxidized by ozone and produce oxides (peroxides) that irritate the skin and reduce its efficacy.

[0041] When petrolatum is used, it is preferable to use purified petrolatum which contains few impurities and is hardly rancid. Impurities are also oxidized to ozone, which also produces oxides (peroxides) that irritate the skin and reduce drug efficacy. As such purified petrolatum, Proto (registered trademark) manufactured by Maruishi Pharmaceutical Co., Ltd., Sun White (registered trademark) manufactured by Nikko Rica Co., Ltd., or the like can be used.

When using polyethylene glycol, it is desirable to use Macrogol ointment specified by the Japanese Pharmacopoeia. The macrogol ointment is a mixture of liquid macrogol 400 and solid macrogol 4000 at a ratio of approximately 1: 1. The mixing ratio may be appropriately changed in order to adjust the viscosity according to the power application. Further, a polymer agent may be added to adjust the viscosity. Macrogol is hygroscopic and can be preserved by mixing with glycerin. It is highly wet and can be used as an ointment.

[0043] The ozone-dissolved mixed solution obtained by diluting the ozone-dissolved glycerin solution with these diluents preferably has an ozone concentration of 80 ppm or more. If the ozone concentration is 80 ppm or more, the sterilizing ability can be exhibited. Further, when the ozone concentration is 100 ppm or more, the sterilizing ability can be more exhibited. Further, when the ozone concentration is 500 ppm or more, a wound healing effect can be obtained, and when the ozone concentration is 100 ppm or more, an excellent wound healing effect can be exhibited as described later.

[0044] The above ozone-dissolved mixed solution is also stored in a refrigerator at 5 ° C or more and 10 ° C or less or frozen and stored at 5 ° C or less to further reduce the amount of ozone released from the ozone-dissolved mixed solution. The ozone concentration can be maintained at a higher level for a longer period of time than when stored at room temperature.

[0045] Further, the ozone-dissolved mixed solution can also be cooled to obtain an ozone-dissolved glycerin solidified product, similarly to the ozone-dissolved glycerin solution. In the case of solidified ozone-dissolved glycerin,

In addition, the ozone concentration at which ozone is released more easily than in the liquid state can be maintained at a high concentration for a longer period.

Concentrated glycerin and ozone were brought into gas-liquid contact to produce an ozone-dissolved glycerin solution. Here, the concentrated glycerin means glycerin having a concentration of 98 wt% or more of the Japanese Pharmacopoeia product.

[0047] As the contact tank, a Teflon (registered trademark) tank having a capacity of 50 L was used. An air diffuser was installed at the bottom of the tank so that ozone could be supplied as fine bubbles into the tank. The ozone generator used was a silent discharge ozone generator with an ozone generation capacity of 100 g / h using oxygen with a concentration of 90% or more as a raw material.

[0048] 22 kg of concentrated glycerin is put into the tank, and 20 L of oxygen is fed into the ozone generator per minute.

The generated gas containing ozone was released from the air diffuser tube into the tank for 7 days to obtain an ozone-dissolved glycerin solution having an ozone concentration of 3000 ppm final.

[0049] The obtained ozone-dissolved glycerin solution was stored at room temperature, refrigerated (about 5 ° C), and frozen (about -20 ° C)! , And the half-life of the ozone concentration was measured. The measurement of ozone concentration was carried out using the method for determining the amount of lithium iodide. [0050] When the obtained ozone-dissolved glycerin solution was stored at room temperature, the ozone concentration was reduced by half in about 6 months. During refrigeration, the ozone concentration was reduced by half in about 16 months. After three years of refrigeration, the rate of change in ozone concentration was 98%, indicating almost no change. This is thought to be because the glycerin in the ozone-dissolved glycerin solution crystallized due to freezing, or the viscosity of the entire solution became higher, and ozone was not released than in the liquid state.

An ozone-dissolved glycerin solution (hereinafter referred to as ozondiel) produced from concentrated glycerin by the above-described method, an ozone-dissolved mixed solution obtained by mixing macrogol ointment (hereinafter referred to as ozone ointment), and a strong electrolytic acid jell And electrolyzed acidic functional water.

[Experimental method]

After the rats were anesthetized with ethyl ether, the skin on the back was disinfected with Hibiten and shaved. Using a Derma Punch (manufactured by Stiefel Laboratorium), four wound sites with a diameter of 5 mm and a depth of about lmm were created. Ozone ointment, ozone jewel, strong electrolytic acidic jewel, and electrolytic acidic functional water were applied to each wound site twice a day (AM 9:00, PM 9:00).

Preparation of Wound Site The diameter of the wound site of the rat was measured on days 1, 3, 5, and 7, and immediately thereafter, the rat was sacrificed and a sample was collected. The measurement of the diameter was performed at four places for one small part, and the average value was used as the measurement result.

[0056] The collected sample was embedded in paraffin to prepare a section, which was then subjected to HE staining, and the epithelium of the sample was analyzed. And the formation of granulation tissue were observed. In addition, Azan staining was performed to examine the degree of proliferation of collagen fibers during the wound healing process.

Compared with the three-day case, the regeneration of granulation tissue was observed in the electrolytic acidic functional water, and the absorption of the fibrin layer was promoted. In the strong electrolytic acid jewel, granulation tissue formation with inflammatory cell infiltration was observed in the subepithelium, and although a little, the regeneration of basal cells and the formation of fibers toward the center of the wound were observed. Admitted. In ozone jewels, granulation tissue formation with inflammatory cell infiltration and regeneration of epithelium from the wound margin were observed. In ozone ointment, inflammatory cell infiltration in granulation tissue was slightly abolished, and relatively good epithelial regeneration was observed.
