  Conventionally, it has been a problem that oxidative stress caused by active oxygen and free radicals causes various diseases such as lifestyle-related diseases. As one method for solving this problem, Non-Patent Document 1 discloses a method for removing oxidative stress by utilizing the antioxidant action of hydrogen.

  On the other hand, hydrogen exists as a gas at normal temperature and normal pressure, and is the lightest gas among the gases present in a molecular state. Therefore, there is a problem in that it immediately diffuses into the air after the occurrence. Even if hydrogen is dissolved in water and stored, the hydrogen in the water is gradually lost over time.

  In order to solve the above-described problem, a method of previously storing hydrogen in a solid substance has been considered. Patent Document 1 discloses a method for producing a powdery magnesium-based hydride by reacting a single magnesium with a hydrogen molecule. The powdery magnesium-based hydride stores hydrogen in advance, and can efficiently generate hydrogen by reacting with water.

On the other hand, in the field of beauty, there is a problem that oxidative stress caused by active oxygen or free radicals directly causes damage to skin, hair, and the like, thereby causing aging, inflammation, and the like.
For example, active oxygen generated when coloring hair is known to cause hairiness after coloring and inflammation of the scalp. In addition, it is also known that active oxygen is generated by exposure to ultraviolet rays for a long time, aging, etc., leading to increased dryness, split hairs, cut hairs, inflammation of the scalp, and the like.

Therefore, also in the field of beauty, it is expected that the antioxidant action of hydrogen will be applied for the purpose of health promotion and anti-aging.
Patent Document 2 discloses a powder bath cosmetic in which hydrogen is generated by containing finely divided magnesium hydride and reacting with water. However, this powder bath cosmetic requires a large amount of water in order to generate sufficient hydrogen at the time of use, and the water used for the reaction of the powder bath cosmetic needs to be hot water.

  Hereinafter, each agent will be described in detail.

<A agent>
In the present invention, the agent A contains magnesium hydride and oil, and does not contain water. Hereinafter, the agent A will be described in more detail.

[Magnesium hydride]
When the agent A contains magnesium hydride, it reacts with water adhering to the skin, hair, or the like, or water in the agent B, and can release a large amount of hydrogen. Thereby, sufficient hydrogen can be secured at the time of skin quality improvement or hair quality improvement, and damage to the skin and hair due to oxidative stress can be repaired.

  Moreover, in this invention, water is not contained in A agent. Therefore, since magnesium hydride having high reactivity with water can be stored in the agent A without contacting with water, the storage stability is also improved.

Magnesium hydride in the agent A is an ionic bond type hydride composed of a bond of Mg ²⁺ and H ⁻ , similarly to the alkali metal hydride, and is produced by reacting magnesium with high pressure hydrogen in a heated state. .
The reaction formula for producing magnesium hydride is represented by the following formula (1).

  Magnesium hydride powder is charcoal gray and stable in air, while in water it decomposes by reacting with water and releasing hydrogen. Therefore, the magnesium hydride in agent A has previously stored hydrogen therein, and reacts with water attached to the skin, hair, etc., or water in agent B, and hydrolyzes it to give hydrogen. It can be released in large quantities. The reaction formula in which magnesium hydride reacts with water is represented by the following formula (2).

  Many substances that generate hydrogen by contact with water have been known, for example, metals such as magnesium and aluminum, which have a higher ionization tendency than hydrogen; hydrogen storage substances such as hydrogen storage coral powder and hydrogen storage silica Is mentioned. These substances can theoretically be used instead of magnesium hydride in the present invention.

  However, magnesium hydride has a hydrogen storage amount per mass of 7.6% (w / w), which is much higher than the hydrogen storage material. In addition, not only hydrogen generated from magnesium hydride but also hydrogen atoms constituting water can be generated as hydrogen by the hydrolysis reaction, so the amount of hydrogen generated by hydrolysis is the hydrogen storage amount of magnesium hydride. It is 15.2% (w / w), which is twice this. Therefore, when hydrogen is generated from water using a metal that has a higher ionization tendency than hydrogen, or when hydrogen in the hydrogen storage material is taken out by dissolving (decomposing) the hydrogen storage material in water, Occurrence can be expected.

  In addition, it is theoretically possible to use hydrogen water instead of magnesium hydride. However, in the case of using hydrogen water, in order to use a sufficient amount of hydrogen to obtain a sufficient effect, a large amount of hydrogen water is required, and other active ingredients of cosmetics and hair treatment agents are diluted. There is a high possibility of hindering the performance of. On the other hand, magnesium hydride exists as a solid at room temperature, and is sufficiently hydrolyzed by water adhering to the skin, hair, or the like, or water in agent B, and generates a large amount of hydrogen as described above. Therefore, it is possible to sufficiently obtain the effect of hydrogen while fully exhibiting the original effects of the cosmetic and the hair treatment agent with a small amount of water compared to hydrogen water.

Furthermore, magnesium hydride is a harmless substance, and Mg (OH) ₂ after hydrogen generation is a safe substance as it is also used for pharmaceuticals. From these points, if the compound that generates hydrogen is magnesium hydride, it is possible to manufacture, transport, and use the substance that generates hydrogen more safely.

On the other hand, the reaction of the above formula (2) has a problem that the surface of magnesium hydride is covered with Mg (OH) ₂ with the reaction, and the reactivity gradually deteriorates. Moreover, the temperature at the time of reaction needs to be higher than normal temperature. Therefore, when the B agent mentioned later contains carbon dioxide, the reaction solution at the time of reacting with the magnesium hydride in the A agent can be made acidic. Thereby, reaction of said Formula (2) advances also at normal temperature, and it becomes possible to generate hydrogen efficiently also at normal temperature.

  The method for obtaining the magnesium hydride in the agent A used in the present invention is not particularly limited, but it can be produced efficiently by the methods disclosed in, for example, Japanese Patent No. 4083786 and Japanese Patent No. 4425990. Is possible.

  Specifically, as disclosed in Japanese Patent No. 4083786, a raw material powder containing magnesium as a main component is held in a hydrogen gas atmosphere sealed in a sealed container, While maintaining the pressure of the hydrogen gas atmosphere at a predetermined pressure, the temperature of the hydrogen gas atmosphere in the enclosure is on the equilibrium curve between the reaction in which single magnesium and hydrogen molecules combine to produce magnesium hydride and the reverse reaction. The coating on the surface of the raw material powder is removed by maintaining the temperature at a temperature higher than the temperature corresponding to the predetermined pressure and at a temperature difference from the temperature within a predetermined value for a predetermined first period. Next, without returning the temperature of the hydrogen gas atmosphere in the enclosure to room temperature, the temperature is lower than the temperature corresponding to the predetermined pressure on the equilibrium curve, and the temperature difference from the temperature is a predetermined value. Within In that the temperature, by maintaining a predetermined second period, the production of magnesium hydride from the raw material powder. According to this method, magnesium hydride having a high hydrogenation rate can be efficiently produced.

  Further, as disclosed in Japanese Patent No. 4425990, instead of powder raw material, a compressed product is prepared by compressing a plurality of flakes mainly composed of magnesium and compressing them in a hydrogen gas atmosphere. You may make it react with gas. According to this method, magnesium hydride is manufactured from flakes containing magnesium as the main component, so it is safer and more efficient to use magnesium hydride with a high hydrogenation rate compared to manufacturing from powder raw materials that may cause dust explosion. Can be manufactured automatically.

  The hydrogenation rate is a percentage of the amount of hydrogen that can be ideally stored according to the molecular weight of magnesium hydride (= 26) and the molecular weight of magnesium (= 24). The mass is measured, and it is obtained as in the following formula (1).

  Magnesium hydride obtained by the above method or the like usually has a hydrogenation rate of about 70 to 100%, preferably about 90 to 100%. In addition, magnesium hydride has a higher hydrogenation rate and is stable against chemical deterioration than other hydrogen storage materials. Therefore, it is a very excellent hydrogen storage material that is easy to handle in terms of workability such as transportation, supply, and storage.

On the other hand, since magnesium hydride is reactive with water, it is gradually decomposed by moisture or the like. Therefore, it is also possible to prevent moisture and the like by incorporating a hygroscopic component into the agent A.
The moisture-absorbing component only needs to contain a component that absorbs moisture, such as silica, sodium sulfate, magnesium sulfate, copper sulfate, calcium chloride, magnesium chloride, alumina, diphosphorus pentoxide, diatomaceous earth, and zeolite. Etc.

The average particle size of the magnesium hydride used in the present invention is not particularly limited, but is preferably 20 μm or less and more preferably 5 μm or less from the viewpoint of reactivity with water.
In addition, an average particle diameter is a 50 wt% diameter obtained by measuring the particle size distribution of magnesium hydride. The 50 wt% diameter is a particle diameter having a 50% cumulative frequency. That is, the particle size is obtained when the magnesium hydride particles having a smaller particle size are accumulated in order and the accumulated value reaches 50%.

  The content of magnesium hydride in the agent A can be appropriately set as long as the effects of the present invention are not impaired. In the present invention, it is particularly preferable to set the content of magnesium hydride to 0.01 to 5% by mass. By setting the content of magnesium hydride to 0.01% by mass or more, a sufficient amount of hydrogen can be generated continuously. Moreover, the amount of unreacted magnesium hydride remaining on the hair or scalp can be reduced by setting it to 5% by mass or less.

[Oil]
As described above, magnesium hydride reacts with water and is hydrolyzed to release hydrogen. Since agent A contains an oil component, magnesium hydride is stored together with the oil component in agent A, and the reaction between magnesium hydride in agent A and water can be prevented from progressing. improves. In addition, user convenience is improved, and quality in the distribution process is easily maintained.

<B agent>
In the present invention, the agent B contains carbon dioxide and water. Hereinafter, the agent B will be described in more detail.

[carbon dioxide]
When B agent contains a carbon dioxide, the reaction solution at the time of reacting with the magnesium hydride in A agent can be made acidic as above-mentioned.

2. Hair Quality Improvement Method The hair quality improvement method according to the present invention is a method of performing at least the contact step (I) and the contact step (II) after performing the contact step (I). Moreover, after passing through said contact process (I)-(II) as needed, heating process (III) can further be performed and contact process (IV) can further be performed. Hereinafter, each step will be described in detail.

(1) Contact process (I)
The contact step (I) is a step of bringing hair A into contact with hair, which contains magnesium hydride and oil, and does not contain water. About A agent, since it is the same as that of what was mentioned above, description is omitted here.

In the contact step (I), the specific method is not particularly limited as long as the agent A can be brought into contact with the hair, and a free method can be appropriately selected.
For example, a method of preparing the agent A into a cream, lotion, gel, paste, powder, solid, foam or spray and applying it to the hair can be mentioned.

  In the present invention, a method of preparing the agent A in the form of foam and applying it to the hair is particularly preferable. This is because, by making the agent A foamy, the convenience of the user is improved and the agent A can be uniformly applied to the entire hair.

  In addition, by mixing magnesium hydride and oil into known hair treatment agents such as shampoos, rinses, treatments, conditioners, hair dyes, etc. (those that do not contain water) and applying them to the hair, It is also possible to perform the contact step (I).

  Moreover, it is preferable that the hair is wet when the agent A is brought into contact with the hair. By bringing the agent A into contact with the hair while the hair is wet, water for the reaction of magnesium hydride is supplied, and the generation of hydrogen occluded inside the magnesium hydride can be promoted efficiently. This is because it becomes possible.

(2) Contact process (II)
The contact step (II) is a step of bringing the agent B containing carbon dioxide and water into contact with the hair after performing the contact step (I). About B agent, since it is the same as that of what was mentioned above, description is omitted here.

The hair quality improving method according to the present invention is characterized in that the contact step (II) is performed after the contact step (I).
As described above, the agent A used in the present invention contains an oil component having a cleansing effect, and after performing the contact step (I), the hair and scalp oils and fats are removed. Then, it becomes possible to introduce | transduce hydrogen efficiently with respect to the hair and scalp of the state from which fats and oils were removed by performing contact process (II).

In the contact step (II), the magnesium hydride in the agent A and the water in the agent B can be reacted to promote the generation of hydrogen occluded in the magnesium hydride.
Furthermore, as described above, carbon dioxide is known to have a blood circulation promoting effect. In the contact step (II), hydrogen generated from magnesium hydride is efficiently removed in a state where the blood flow in the scalp is increased. It is possible to penetrate into the hair.

In the contact step (II) of the hair quality improvement method according to the present invention, the specific method is not particularly limited as long as the agent B can be brought into contact with the hair after the contact step (I) is performed. The method can be selected as appropriate.
For example, the B agent containing carbon dioxide and water is prepared in the form of cream, lotion, gel, paste, powder, solid, foam or spray, and this is applied to the hair. It is done.

  In the present invention, a method of preparing the B agent in the form of foam and applying it to the hair is particularly preferable. This is because by making the agent B foamy, the convenience of the user is improved and the agent B can be uniformly applied to the entire hair.

  It is also possible to perform the contact step (II) by mixing carbon dioxide and water with known hair treatment agents such as shampoos, rinses, treatments, conditioners and hair dyes and applying them to the hair. It is.

  In the present invention, as described later, it is preferable that the same effect as that of the shampoo can be exhibited with the single agent B. This is because when the agent A and the agent B are removed from the hair, it is not necessary to use another hair treatment agent, and the convenience for the user is improved.

(3) Heating step (III)
In the hair quality improving method according to the present invention, the heating step (III) can be further performed after the contact steps (I) to (II), if necessary. The heating step (III) is a step of heating the hair.

Usually, as will be described later, the contact steps (I) to (II) are carried out, followed by a standing time step 2 for a predetermined time, and then the agent A and agent B are removed from the hair, and then the heating step (III). I do.
Although heating process (III) is not an essential process in this invention, as shown in the Example mentioned later, in order to improve the water | moisture content in hair more, it is preferable to perform heating process (III).

  Moreover, in the drying process, when the drying process is performed by heating, the drying process by heating can be used as the contact step (III), but it is better to heat at a higher temperature within a range not damaging the hair. Further, since the amount of moisture in the hair is improved, it is preferable to perform a heat treatment at a high temperature even after the drying treatment by heating.

  The heating temperature in the heating step (III) is not particularly limited as long as the effects of the present invention are not impaired, and can be appropriately set according to the equipment and purpose used for heating. In this invention, 60-230 degreeC is preferable, as for the heating temperature in heating process (III), 100-230 degreeC is more preferable, and 180-220 degreeC is still more preferable. The reason for this is as follows.

  In this invention, as shown in the Example mentioned later, the result that the moisture content in hair rises is obtained by heating hair after passing through said contact process (I)-(III). By setting the heating temperature to 60 ° C. or higher, the amount of moisture in the hair can be increased more reliably. Moreover, the hair damage by heat can be prevented by setting heating temperature to 230 degrees C or less.

The heating method in the heating step (III) is not particularly limited as long as the effects of the present invention are not impaired, and a heat treatment apparatus or the like used in normal hair treatment can be appropriately selected and used.
For example, exothermic devices such as a hair dryer, hot curler, heater, and hair iron can be used.

  The heating step (III) can also be performed in two stages. For example, after removing agent A and agent B from hair, after first evaporating the moisture on the hair surface with a drier, etc., and further using a hair iron etc., the hair is heated at a higher temperature. It is also possible to increase the amount of water inside more effectively.

(4) Contact process (IV)
In the hair quality improving method according to the present invention, the contact step (IV) can be further performed as necessary. The contact step (IV) is a step of bringing the C agent containing the other substances mentioned above into contact with the hair. About C agent, since it is the same as that of what was mentioned above, description is omitted here.

  Although the contact step (IV) is not an essential step in the present invention, the contact step (IV) can be further performed for the purpose of promoting the generation of hydrogen from magnesium hydride at room temperature.

  The time point at which the contact step (IV) is performed is not particularly limited. For example, before the contact step (I), after the contact step (I) and before the contact step (II), after the contact step (III), etc. Can be done.

  It is also possible to perform the contact step (IV) by mixing other substances with known hair treatment agents such as shampoos, rinses, treatments, conditioners, hair dyes, etc. and applying them to the hair. is there.

(5) Specific Flow of Hair Quality Improvement Method Hereinafter, a specific flow of the hair quality improvement method according to the present invention will be described with examples.

<Pre-shampoo>
In the method for improving hair quality according to the present invention, pre-shampooing can be performed to remove dirt, hair dressing, and the like attached to the hair surface before actual hair quality improvement. This pre-shampoo is not an essential step in the hair quality improvement method according to the present invention, but is preferably performed when, for example, silicone oil or the like adheres to the hair. This is because preshampooing can improve the appearance and feel of hair after improving the hair quality.

  In addition, before the hair quality improving method according to the present invention is performed, the hair and scalp are pre-wetted with a pre-shampoo to supply water for the reaction of magnesium hydride in the agent A, so that the hydrogen can be efficiently It becomes possible to promote the generation of hydrogen occluded in the magnesium halide.

  Even if pre-shampooing is not performed, water for reacting magnesium hydride in the agent A can be supplied by pre-wetting the hair and scalp with a spray bottle or the like.

<Contact process (I)>
Next, the contact process (I) which makes A agent contact hair is performed. For example, according to a conventional method, the agent A is applied to the hair. The contact step (I) is the same as described above.

  Application of agent A to the hair is preferably performed on wet hair. By applying the agent A while the hair is wet, water for reacting the magnesium hydride in the agent A is supplied, and the generation of hydrogen occluded inside the magnesium hydride is efficiently promoted. Because it becomes possible. Moreover, since a processing agent can be apply | coated more uniformly, a user's convenience also improves.

<Left process 1>
After the agent A of the present invention is brought into contact with the hair, it is possible to perform the leaving step 1 in which the agent is left as it is for a predetermined time as reported.

  In the case of the leaving step 1, it is possible to appropriately perform a treatment such as heating.

<Contact process (II)>
Next, the contact process (II) which makes B agent contact hair is performed. For example, the B agent is applied to the hair according to a conventional method. The contact step (II) is the same as described above.

<Left process 2>
In this invention, after making B agent of this invention contact hair, it is preferable to perform the leaving process 2 which is left as it is for a predetermined time. By performing the leaving step 2, the hydrolysis reaction of magnesium hydride in the agent A and water continuously proceeds on the hair surface, inside the hair, and the scalp to generate hydrogen. This hydrogen is combined with active oxygen in the surface of the hair, in the hair, and in the scalp to generate water, and the amount of water in the hair and scalp can be improved.

  The time for the leaving step 2 is not particularly limited, and can be set as appropriate according to the quality of the hair, hair and / or scalp, etc., but it is preferably left for 1 to 20 minutes, preferably 5 to 10 minutes. It is more preferable to leave it.

  In the case of the leaving step 2, it is possible to appropriately perform a treatment such as heating.

<Removal process>
If necessary, agent A and agent B present on the hair surface can be removed.
The removal method of A agent and B agent is not specifically limited, For example, it can remove using hair treatment agents, such as a shampoo, rinse, a treatment, and a conditioner.

  In addition, when the same agent as B agent can exhibit the same effect as shampoo, it is not necessary to use a hair treatment agent such as shampoo, rinse, treatment, conditioner or the like separately. This improves the convenience for the user.

  Furthermore, after the removal of the agent A and the agent B, it is possible to further perform a treatment or the like as appropriate.

<Drying process>
After removing the A agent and the B agent, moisture remaining on the hair surface can be dried as necessary. The method for the drying treatment is not particularly limited, and examples thereof include a method for drying towels and a method for performing drying treatment by heating using a hair dryer after towel drying.

  In the drying process, when a drying process by heating is performed using a hair dryer or the like, the contact process (III) described later can be performed.

<Contact process (III)>
After the moisture remaining on the hair surface is dried, in the hair quality improvement method according to the present invention, it is preferable to further perform the contact step (III) as described above. The contact step (III) is the same as described above.

  Moreover, in the drying process, when the drying process is performed by heating, the drying process by heating can be used as the contact step (III), but it is better to heat at a higher temperature within a range not damaging the hair. Since the amount of water in the hair is improved, it is preferable to further perform the contact step (III) even after the drying treatment by heating.

  Hereinafter, the present invention will be described in more detail based on examples. In addition, the Example demonstrated below shows an example of the typical Example of this invention, and, thereby, the range of this invention is not interpreted narrowly.

<Experimental example 1>
In Experimental Example 1, the hydrogen generation effect and the hydrogen generation sustaining effect of the cosmetic kit according to the present invention were examined.

(1) Preparation of Agent A and Agent B [Example 1] Agent A: Cleansing agent / Agent B: Pack Agents A and B according to Example 1 were prepared with the formulations shown in Tables 1 and 2 below.

[Comparative Example 1] Agent A: Cleansing Agent / Agent B: Pack During the formulation of Agent A of Example 1 shown in Table 1 above, water was added instead of magnesium hydride, and the other components were Agent a was prepared with the same formulation as in Example 1.
Moreover, b agent was prepared by the mixing | blending similar to the mixing | blending of B agent of Example 1 shown in the said Table 2.

[Comparative Example 2] Agent A: Cleansing Agent / Agent B: Pack During the formulation of Agent A of Example 1 shown in Table 1, without blending oil (mineral oil, squalane), water was blended instead. For other components, preparation a was prepared with the same formulation as in Example 1.
Moreover, b agent was prepared by the method similar to the mixing | blending of B agent of Example 1 shown in the said Table 2.

[Comparative Example 3] Agent A: Cleansing Agent / Agent B: Pack During the formulation of Agent A of Example 1 shown in Table 1, active hydrogen water (trade name “Crystal Hydrogen” was used instead of magnesium hydride. Water ”(manufactured by Cocosys Co., Ltd.)) was added, and other ingredients were prepared in the same manner as in Example 1 to prepare agent a.
Moreover, b agent was prepared by the mixing | blending similar to the mixing | blending of B agent of Example 1 shown in the said Table 2.

[Comparative Example 4] Agent A: Cleansing Agent / Agent B: Pack During the formulation of Agent A of Example 1 shown in Table 1, magnesium hydride and oil (mineral oil, squalane) were not blended, but instead water A was prepared by mixing the other components in the same manner as in Example 1.
Moreover, b agent was prepared by the mixing | blending similar to the mixing | blending of B agent of Example 1 shown in the said Table 2.

(2) Test method After preparing agent A prepared in Example 1 and agent a prepared in Comparative Examples 1 to 4, each agent was allowed to stand at room temperature for 9 hours. Thereafter, water was added to each agent, and at the same time, a methylene blue reagent (manufactured by Wako Pure Chemical Industries, Ltd.) was also added dropwise to examine the color change.
Moreover, about what was colored blue, the time until blue disappeared was measured.

(3) Test results and discussion The test results are shown in Tables 3 and 4 below.

  As shown in Table 3, the agent A prepared in Example 1 was colored blue immediately after dropping methylene blue. Therefore, it turned out that generation | occurrence | production of hydrogen starts the A agent prepared in Example 1 immediately after preparation. The color reaction lasted 565 minutes (about 9 hours or more). From this result, it was found that the agent A prepared in Example 1 generated hydrogen immediately after the preparation, and continued to generate hydrogen continuously for about 9 hours or more thereafter.

On the other hand, as shown in Table 4, the agent a prepared in Comparative Examples 1 and 4 in which neither magnesium hydride nor hydrogen water was blended showed any color reaction even when methylene blue was added dropwise.
Further, the agent a prepared in Comparative Example 2 containing magnesium hydride showed a color reaction immediately after the dropwise addition of methylene blue, but all the color reaction disappeared after 11 minutes. The agent a prepared in Comparative Example 2 does not maintain the color reaction even though it contains magnesium hydride because the agent a prepared in Comparative Example 2 contains water. This is because the hydrolysis reaction of magnesium hydride started immediately after that, and hydrogen continued to be generated even after being left for 9 hours.
Furthermore, the agent a prepared in Comparative Example 3 containing hydrogen water generated hydrogen immediately after the preparation, and hydrogen was already lost while left for 9 hours. No reaction was seen at all.

  From these results, it was found that the agent A used in the cosmetic kit according to the present invention has good storage stability and can continuously generate hydrogen during use. .
