Description

  The present invention relates to a mist providing method, and more particularly to a mist providing method capable of maintaining a stable hydrogen concentration and obtaining a mist with faster diffusion.

  In recent years, soft drinks such as water and tea filled with hydrogen gas have been sold. This is intended to reduce active oxygen present in the human body by ingesting hydrogen gas filled in a liquid.

  Active oxygen, on the other hand, plays an important role in creating ATP (adenosine triphosphate) in the citric acid cycle, and is also essential for life support and also plays a role in eliminating foreign substances that have entered the body. Is known. In addition, active oxygen that has not been used in in vivo reactions or the like is usually decomposed by enzymes present in cells. However, not all active oxygen is decomposed by the enzyme, and surplus active oxygen is present without being decomposed. As a result, cells are damaged by surplus active oxygen, causing diseases such as cancer and lifestyle-related diseases, and aging, and eliminating surplus active oxygen is required for health maintenance.

  Therefore, in recent years, hydrogen has been used as a substance that eliminates such surplus active oxygen. This is because hydrogen has a very low molecular weight and is easily absorbed into the body, and further changes to water when it reacts with active oxygen, and has high safety reasons. Also, among the many active oxygens, only hydroxy radicals are selected and reduced, and the active oxygen useful for the body is not affected.

  In this way, the pathological effectiveness of hydrogen, which is thought to lead to disease prevention and health promotion without any particular harm, has been reported in many academic journals such as Non-Patent Documents 1-10. There is no excuse.

  As described above, ingestion of hydrogen gas has useful effects such as disease prevention and health promotion, but it is difficult to maintain a high amount of dissolved hydrogen as it is after hydrogen gas is dissolved in a liquid. For example, if water filled with hydrogen gas is stored in a plastic container such as a PET (polyethylene terephthalate) bottle, most of the hydrogen will be removed in a few days even if it is sealed. Even high efficacy cannot be obtained.

  In this regard, in Patent Document 1, a liquid container having a flexible exterior is encapsulated with a liquid in which hydrogen molecules are dissolved, a pressure member is attached to a part or the whole of the liquid container, and pressure is applied from the outside. Disclosed is a method for maintaining the amount of dissolved hydrogen by maintaining the added state.

  Further, Patent Documents 2 to 4 disclose cosmetics containing hydrogenated water containing 0.5 to 1.5 ppm of hydrogen and having a redox potential of −400 mV or less. Further, Patent Documents 5 and 6 disclose a method of maintaining a bubble by gelling after enclosing hydrogen gas in fine bubbles.

  On the other hand, Patent Documents 7 and 8 disclose an aerosol composition containing carbon dioxide for the purpose of obtaining excellent foaming properties and the like.

  The technique described in Patent Document 1 focuses on the proportional relationship between gas solubility and pressure (Henry's law), and by applying pressure from the outside to a container containing a hydrogen-dissolved liquid, Is trying to maintain a high amount of dissolved hydrogen. However, when this method is employed, a mechanism for applying pressure to the container is required. Also, the material of the container must be able to withstand this pressure, and it must be a flexible material that can convert external pressure to internal pressure. Furthermore, if the container itself for storing the liquid is not highly sealed or has a low gas permeability, the external pressure may cause the hydrogen gas in the liquid to leak or permeate outside. is there.

  Moreover, although the technique of patent documents 2-4 can raise hydrogen concentration temporarily, there exists a problem that the fall of hydrogen concentration with time is remarkable. Therefore, in the techniques described in Patent Documents 5 and 6, hydrogen concentration is maintained by gelling after enclosing hydrogen gas in fine bubbles, but it is maintained by confining it in a solid gel. Therefore, there is a problem that the hydrogen concentration cannot be maintained in a low viscosity state such as a gel melting.

  Furthermore, in the techniques described in Patent Documents 7 and 8, since carbon dioxide is used as the foaming gas, when mist is generated by aerosol, the diffusion of mist is slow, and the effect is such as permeability due to the large mist. There is a problem that cannot be obtained sufficiently.

  Accordingly, an object of the present invention is to provide a mist providing method capable of solving the above-mentioned problems of the prior art, maintaining a stable hydrogen concentration, and obtaining a mist with faster diffusion.

  As a result of intensive studies to solve the above problems, the present inventor has found that the above object can be achieved by using hydrogen as an aerosol propellant, and has completed the present invention.

  In other words, the mist providing method of the present invention is a method for finely applying the aerosol mist in which the propellant is injected as a mist by a propellant, and the mist is injected by adding hydrogen to the propellant under pressure. It is characterized in that the diffusion rate of the is increased.

  In the mist providing method of the present invention, it is preferable that the hydrogen contained in the propellant is derived from hydrogen contained in the propellant.

  Furthermore, in the mist providing method of the present invention, the propellant is preferably a gas obtained by mixing an inert gas with hydrogen.

  Furthermore, in the mist providing method of the present invention, the propellant is preferably a gas in which hydrogen is mixed with nitrogen or carbon dioxide, and compared with a case where the propellant is only nitrogen or carbon dioxide at the diffusion rate. It is preferable that the height is increased.

In the mist providing method of the present invention, the spray material is preferably a cosmetic, and the spray material is preferably a beverage.

  ADVANTAGE OF THE INVENTION According to this invention, the mist provision method which can maintain hydrogen concentration stably and can obtain mist with quick diffusion can be provided.

It is sectional drawing which shows an example of the aerosol which can be used for this invention.

Hereinafter, the hydrogen-containing aerosol of the present invention will be specifically described.
FIG. 1 is a cross-sectional view showing an example of an aerosol that can be used in the present invention. In the figure, 1 is an actuator (push button), 2 is a valve, 3 is a standpipe, 4 is a pressure vessel, 5 is a propellant, 6 is mainly a propellant, and may contain a propellant. The aerosol 7 pushes the actuator 1 to open the valve 2 and the propellant 5 applies pressure in the direction of arrow A, so that the propellant 6 is injected in the direction of arrow B through the stand pipe 3.

  In the present invention, hydrogen is used as the propellant 5. Hydrogen has a low molecular weight, and it is considered that hydrogen enters between the contents, for example, between water and water molecules, and can easily peel off water molecules. In addition, a propellant containing hydrogen (for example, water) has a faster diffusion rate than a propellant containing other gases such as conventional nitrogen gas and carbon dioxide. Furthermore, hydrogen itself has a higher diffusion rate than other gases such as conventional nitrogen gas and carbon dioxide. Therefore, compared with the case where conventional nitrogen gas or carbon dioxide is used, the mist is diffused as fine and fine mist, and a mist that is gentler to the skin can be obtained when sprayed toward the skin.

  In the present invention, the hydrogen injection pressure at 20 ° C. is preferably 0.4 to 0.9 MPa, and more preferably 0.7 to 0.8 MPa. By setting the hydrogen injection pressure within the range, the compatibility between hydrogen and the propellant 6 can be improved and diffused as a finer and finer mist. Can be obtained.

  Furthermore, in the present invention, it is preferable that the hydrogen is hydrogen generated by electrolysis. For example, an aqueous solution containing 25% KOH is placed in an alkaline electrolytic cell, and this is electrolyzed to generate hydrogen, which can be used as a propellant. As a result, the conventional filling with a hydrogen cylinder requires about 15 MPa, whereas the filling can be performed at a pressure of about 1 MPa or less, and the aerosol can be filled more safely. Further, by using hydrogen generated directly from the hydrogen generator on-site as a propellant, the cost can be remarkably reduced as compared with the case of supplying from a cylinder.

  In the present invention, the ratio of the propellant 5 and the propellant 6 in the aerosol is not limited as long as the propellant 6 can be jetted, but the volume ratio is preferably 40:60 to 90:10, 45:55 More preferably, it is -80: 20, and it is still more preferable that it is 50: 50-70: 30. Thereby, the injection substance 6 can be injected more gently, and a soft feeling can be given at the time of use.

  Further, the propellant 6 of the present invention is not limited as long as the effects of the present invention can be obtained, but it is preferably a liquid, and particularly preferably water. When water is used as the propellant 6, it is usually possible to inject water that tends to form water droplets as an extremely fine mist. Furthermore, the useful effect which hydrogen has can be acquired. Here, the liquid is a broad concept including fluid liquids, and means liquids that can be ejected with aerosols, excluding solids and gases.

  Furthermore, cosmetics can be used as the propellant 6. In such a case, since the cosmetics can be sprayed as a mist that is gentler to the skin than normal cosmetics, only the useful effect of hydrogen is obtained. In addition, the effect of cosmetic ingredients can be enhanced. For example, if a hair growth agent is used, the hair growth effect can be further increased, and if a moisturizing cosmetic is used, the penetration into the skin can be further increased and the moisturizing power can be increased.

  Moreover, since a drink can also be used as the injection substance 6, in such a case, since a drink can be injected as a finer mist than a normal drink, not only the useful effect which hydrogen has but more The permeability can be increased, and for example, it can be effective for measures against heat stroke.

  Furthermore, in the present invention, as the aerosol 7, a member that can be used for a normal aerosol can be used as long as the effects of the present invention are not hindered. In particular, from the viewpoint that the hydrogen concentration can be stably maintained, for example, a metal, glass, or the like can be used as the pressure vessel 4, and a structure that does not leak hydrogen such as vapor deposition of aluminum is required.

  In the present invention, the origin of hydrogen used as a propellant is not particularly limited. Furthermore, it is most preferable that only hydrogen is filled, but not only hydrogen but also an inert gas may be mixed. Examples of the inert gas include gases having poor reactivity such as nitrogen gas and carbon dioxide gas, in addition to group 0 elements of the periodic table. These gases are extremely stable and do not combine with other elements. In that case, the hydrogen concentration is preferably 3.9% of the lower explosion limit. Thereby, dangers, such as ignition, can be prevented.

  The method for storing a hydrogen-containing aerosol according to the present invention is characterized in that the hydrogen-containing aerosol 7 is stored with the bottom of the hydrogen-containing aerosol 7 facing upward. Specifically, the pressure-sensitive container 4 is stored so that the bottom of the pressure-resistant container 4 comes to the top with the top having the actuator 1 facing downward. Thereby, since the propellant 5 collects in the bottom part of the pressure vessel 4, hydrogen leakage from the actuator 1 or the like can be prevented. Therefore, the hydrogen concentration can be maintained more stably, and a mist with faster diffusion can be obtained.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail using an Example, this invention is not limited to these Examples.
