However, in the techniques of Patent Documents 1 to 5, carbon dioxide gas at the temperature of hot water to be bathed (about 41 ° C.) hardly dissolves in water (see FIG. 3). However, it is difficult to obtain percutaneous absorption of carbon dioxide from the skin into the blood vessels from hot water in which only carbon dioxide is dissolved, and there is a limit to obtaining the above-mentioned health promotion effect such as blood circulation promotion.

On the other hand, the carbonated spring baths described in the techniques of Patent Documents 6 and 7 cannot cause a carbon dioxide gas foaming reaction from carbonate or the like unless it is acidic. It was found that there was room for improvement as a bathing agent because the health promotion effect such as promotion was not obtained.

  According to the invention shown in claim 1, 4 or 5, the dissolution of the gas component from the carbon dioxide dissolver in hot water is drastically improved, and there exists a high concentration of bicarbonate ions that are easily dissolved in blood. Therefore, it is expected that the effect of promoting health such as blood circulation promotion can be sufficiently exerted by transcutaneous absorption of the carbon dioxide component instantaneously and efficiently.

  The invention according to claim 1, 4 or 5, wherein when an organic acid is used in combination, the percutaneous absorption efficiency of the carbon dioxide component is instantaneously performed, thereby sufficiently exerting health promotion effects such as blood circulation promotion.

  According to the preferred embodiments of the present invention shown in the above (1), (2) and (3), the blown carbon dioxide component easily and instantaneously changes into bicarbonate ions, so that the concentration is extremely high. In addition to being able to be dissolved in hot water and improving the efficiency of transdermal absorption and exerting health promotion effects such as blood circulation promotion, there is a high concentration of bicarbonate ions even without blowing carbon dioxide continuously. In order to continue, it is possible to achieve an equilibrium such that carbon dioxide gas foams with a slight stimulus just by touching the body, and it is absorbed into the blood to expand the blood vessels and make the hot water with a sustained health promotion effect. In addition, according to the inventions shown in the above (3) and (4), the beauty and beauty effects are remarkable.

  According to the present invention, it is possible to remarkably suppress or eliminate the odor of tap water.

  The present invention is described in detail below.

  Conventionally, according to the carbon dioxide gas dissolvers shown in Patent Documents 1 to 5 and the like, even when the solubility of carbon dioxide gas in hot water is improved as compared with the case where these dedicated dissolvers are not used, the carbon dioxide gas is dissolved. It has been found that since hot water becomes slightly acidic, the dissolved carbon dioxide gas is likely to volatilize in the air, and dissolution in blood having a pH of about 7.3 to 7.4 is unlikely to occur.

The inventors of the present invention have further researched on the percutaneous absorption of the carbon dioxide component dissolved in hot water. Carbon dioxide is slightly acidic as free carbonate ion when dissolved in hot water. It turns into carbonate ion and can be dissolved in hot water at high concentration. Since blood vessels have neutral pH, carbon dioxide dissolves as bicarbonate ion, but in the slightly acidic free carbon dioxide spring, carbon dioxide that touches the skin is a body fluid. It is neutralized by the substance and absorbed into the skin through percutaneous absorption, resulting in health benefits such as the expansion of blood vessels and warming of the body. Therefore, carbon dioxide springs are said to have no effect unless the gas is dissolved at a high concentration, so that a lot of fine bubbles of gas adhere to the skin at 1000 ppm or more, and the gas has to be sent constantly. In addition, most of the carbon dioxide baths that add organic acid to bicarbonate and foam carbon dioxide were designed to be acidic, so that no matter how much carbon dioxide foams and is generated, carbon dioxide that touches the skin can be neutralized. In fact, it is not possible to become bicarbonate ions and PH is not absorbed into neutral blood vessels.

  In addition, in the acidic state, carbon dioxide easily escapes into the air and was absorbed through the skin, and there was almost no action or effect to warm the body. If there were, visually enjoy the bubbles, such as calcium sulfate and magnesium sulfate Most of the bath additives had only the effect of preventing the hot water puddle due to the salt concentration effect.

  In the first place, the effect of natural carbonated springs is that carbon dioxide is not absorbed through the pH of blood, but carbon dioxide components are neutralized by touching body fluids from the skin and converted into bicarbonate ions. By the carbonated spring theory based on the new discovery that ions should be absorbed transdermally, the present inventors have found that carbon dioxide gas should be converted into bicarbonate ions and absorbed through the skin to promote blood circulation and warm the body. Has been identified.

  Carbon dioxide gas has low solubility in hot water at a bathing temperature (about 41 ° C.) (see FIG. 3), and is easily volatilized in acidity. Carbon dioxide gas is absorbed in a neutral pH range close to a specific blood. The present inventors have discovered that, if dissolved, carbon dioxide gas can be changed into bicarbonate ions, and the equilibrium can be shifted as far as possible to produce hot water containing a high concentration of bicarbonate ions. is there.

  Therefore, if carbon dioxide gas is dissolved in hot water in which the preparation kit is dissolved in the specified pH range, hot water containing bicarbonate ions at a high concentration can be obtained. Compared with the case of the above, it is possible to obtain a highly concentrated bicarbonate ion spring, which is much more efficient than the case where a bathing agent made of carbonate or organic acid is used to generate carbon dioxide gas and obtain a health effect by percutaneous absorption. Therefore, it is possible to improve the health promotion effect such as the promotion of blood circulation.

  That is, as a result of detailed examination of the effects of natural carbonated springs by the present inventors, as a result of dissolution of carbon dioxide gas as free carbonate ions in natural carbonated springs, even if the spring water is slightly acidic, it is not due to acidic components, but a slight minus. It is weak acidity (acidity not acid excess) due to ion dissociation, and carbon dioxide is neutralized and becomes bicarbonate ion just by touching body fluid such as skin and hair into neutral blood. Because it is absorbed, carbon dioxide gas is not absorbed directly through the skin, but the conventional carbon dioxide gas is absorbed directly through the skin, and it is explained as if carbon dioxide is dissolved in the blood. It begins with ascertaining that it is a misperception.

  In general, the explanation of the effects of carbonated springs describes that carbon dioxide gas is directly absorbed through the skin, but this is an interpretation that cannot be seen from the pH of blood. In the experiment in a room filled with carbon dioxide, it has been proved that it is not absorbed in the air.

  Most body fluids such as blood are neutral and have a pH of about 7.3 to 7.4. If the body fluid is neutral, the carbonate component is chemically present only as bicarbonate ions, the component absorbed percutaneously into the blood vessels is bicarbonate ions, and the dissolved state in the blood is only bicarbonate ions. It should be.

  In the present invention, the most preferable embodiment is that carbon dioxide dissolved from a carbon dioxide dissolver is obtained, and the dissolved carbon dioxide gas is obtained by adding a kit preparation in which the pH of the solution is the same as that of body fluid such as blood. Has been found to be neutralized and converted into bicarbonate ions and transdermally absorbed into the blood vessels. No matter how high the carbon dioxide is dissolved from the carbon dioxide dissolver, Even if it is a bathing agent that is foamed in combination with an organic acid and has a neutral pH after dissolution, the same effect cannot be obtained. By blowing and dissolving carbon dioxide in a gaseous state with neutral PH, Carbon dioxide gas instantly changes to bicarbonate ions, creating a high concentration bicarbonate spring, increasing transdermal absorption, dissolving in blood vessels, increasing blood circulation, warming the body, etc. To continuously demonstrate It is presumed.

The regulation of PH is measured as PH at a concentration of about 0.05% to 0.5% of a tablet or powder / granule used in the present invention (also collectively referred to as “kit formulation” in the present invention). Is reasonable.
This PH measurement is preferably PH immediately after dissolution, and even if PH is neutral, bicarbonate ions in the hot water volatilize the carbon dioxide gas and gradually rise. For example, the pH of hot water immediately after dissolution is 7. Even if it is 0, it becomes about 7.5 after 24 hours. If air is introduced and foamed, the carbon dioxide gas will volatilize in a larger amount, and the pH may exceed 8.5. Therefore, the definition of PH in the present invention is immediately after dissolution of the kit preparation in hot water.

  When the kit preparation of the present invention is a hard tablet with high hardness, the generated carbon dioxide bubbles are very fine, and micro-sized carbon dioxide bubbles of a certain diameter or less can be efficiently generated from the tablets for a long time. In addition to carbon dioxide supplied in a gaseous state, carbon dioxide dissolved in hot water can be supplied, and high-concentration bicarbonate ions can be dissolved. Thus, without using an expensive carbon dioxide dissolver, in the present invention, carbon dioxide gas is supplied through a foaming device such as a sintered stone for breeding tropical fish or the like (included in the “carbon dioxide dissolver” of the present invention). A sufficient effect can be obtained by dissolving.

  In the present invention, “hot water” refers to so-called water, warmed or heated hot water, or a mixture of both. In the present invention, “amount” represents “mass” unless otherwise specified, “%” represents “mass%” unless otherwise specified, and “part” represents “part by mass” unless otherwise specified. Represents.

The schematic block diagram which shows one Example of the manufacturing apparatus of the carbon dioxide containing hot water which concerns on this invention Principle of forced carbon dioxide dissolution using hollow fiber membranes and membranes Graph showing the solubility of carbon dioxide in water, that is, the temperature effect (under 1 atm) of saturated solubility of carbon dioxide (Henry's law)

  Hereinafter, the manufacturing method and manufacturing apparatus for carbon dioxide-containing hot water and a kit preparation for a carbon dioxide dissolver according to the present invention will be described based on examples.

An embodiment of the carbon dioxide-containing hot water manufacturing apparatus according to the present invention is shown in FIG. 1, wherein 1 is a bathtub, 2 is hot water stretched on the bathtub 1, and 3 is a solution of gaseous carbon dioxide in hot water. Carbon dioxide gas dissolvers for obtaining carbon dioxide-containing hot water 4 and kit preparations, respectively.
The kit preparation of the present invention is preferably a tablet or powder / granule, and includes a so-called bath preparation or bath preparation in which a certain amount is packaged in one form in an easy-to-use form. And when not using a carbon dioxide gas dissolving device together, it is possible to use as a bath agent or a bath agent.

  In the present invention, any known and publicly known carbon dioxide dissolver for obtaining carbon dioxide-containing hot water by dissolving carbon dioxide in a gaseous state in hot water can be adopted without any particular limitation. A representative example will be described as follows.

  As in the technique of Patent Document 1, a dissolver that dissolves carbon dioxide gas in hot water and a gas cylinder that supplies carbon dioxide gas are integrally disposed on a movable base, and the dissolver has a hollow fiber membrane. In this configuration, carbon dioxide gas is dissolved in hot water.

Of course, in the present invention, the effect of the invention is exhibited even without a hollow fiber membrane. In particular, it is also a great effect of the present invention that a sufficient effect can be obtained by blowing carbon dioxide gas through small sintered stones for raising tropical fish and goldfish.
In the present invention, even if carbon dioxide is dissolved little by little, it is easily dissolved at a high concentration while instantaneously changing to bicarbonate ions. Therefore, the probability that the carbon dioxide escapes into the air can be extremely reduced, and a hollow fiber membrane or the like is expensive. As described above, this is a great effect in that a simple system is unnecessary.

  As in the technique of Patent Document 2, the hot water in the bathtub is circulated outside the bathtub by a circulation pump, and the hot water is circulated through the hollow fiber membrane 5 built in the carbon dioxide gas dissolver disposed in the circulation channel. In this configuration, the carbon dioxide gas supplied from the carbon dioxide gas cylinder is dissolved. Of course, in this case as well, the dissolution of bicarbonate ions from carbon dioxide gas proceeds efficiently so that the hollow fiber membrane may or may not be present.

  As in the technique of Patent Document 3, carbon dioxide gas is supplied from a carbon dioxide gas cylinder to a dissolver disposed in a hot water circulation channel, and a hollow fiber membrane built in the dissolver (in this case, there is no hollow fiber membrane). In other words, the carbon dioxide gas that has passed through is dissolved in hot water.

  As in the technique of Patent Document 4, raw water is supplied from a water supply pipe to a carbon dioxide adding part, carbon dioxide is dissolved in raw water flowing in the carbon dioxide adding part due to a difference in potential energy, and the raw water in which carbon dioxide is dissolved is discharged. It is the structure which discharges from an exit.

As in the technique of Patent Document 5, the hot water in the bathtub is led to a carbon dioxide dissolver disposed outside the bathtub by an underwater pump, and the hot water circulating through the hollow fiber membrane built in the carbon dioxide dissolver is supplied from the carbon dioxide gas cylinder. It is the structure which melt | dissolves the carbon dioxide supplied.
In another configuration, gas is jetted into a small tank filled with water from a handy small carbon dioxide gas cylinder, carbon dioxide is mixed with water, and carbon dioxide-dissolved mist is generated.
It has been found that a great effect can be obtained even when the kit preparation of the present invention is dissolved in water in this case.

  Next, the PH adjustment kit preparation used in the present invention will be described in detail. Hereinafter, this preparation may be referred to as a carbonate or bicarbonate bath or bath.

The carbonate used in the present invention has a broad meaning including bicarbonate, and is preferably sodium hydrogen carbonate, potassium hydrogen carbonate, sodium carbonate, or potassium carbonate, and particularly preferably sodium hydrogen carbonate. It is preferable to supply with powder and granules.

  Further, as the organic acid used together with the carbonate, a general organic acid is preferable from the viewpoint of high buffering capacity. For example, citric acid, succinic acid, fumaric acid, malic acid, adipic acid, and the like can be used. Citric acid is combined with sodium bicarbonate for optimal pH adjustment kit formulation due to its high neutralization reaction and the beauty and beauty effects on the skin when taking a bath. It is the most preferable embodiment that the effects of the present invention can be exhibited most remarkably when used in combination with a gas melting apparatus such as a sintered body.

  Workability to prescribe a certain amount of organic acid, especially succinic acid, fumaric acid, malic acid, citric acid, etc., and anhydrous sodium carbonate, etc., to the granulated product of bicarbonate. In view of the above, it is preferable to use these kit preparations by making each of the materials coated with polyethylene glycol # 6000, # 1450, etc., and then compressing them under high pressure to form tablets of a certain size. It can be used conveniently, and by making tablets with a certain hardness or higher, carbon dioxide gas can be supplied by foaming a strong neutralization reaction even in tablets, so carbon dioxide gas is not only used as a PH adjuster but also as a cylinder. It can also be supplied from a kit preparation, which makes the kit preparation more preferable in terms of cost.

  In the PH adjustment kit formulation of the present invention, any publicly known and publicly available PH adjusters other than carbonates and organic acids can be used without any particular limitation, and in particular, using a PH adjuster as a food additive, Bathing agents are preferred for safety because they may enter the eyes and mouth. For example, trisodium citrate (sodium citrate), disodium citrate, monosodium citrate, potassium gluconate, sodium gluconate, disodium succinate, sodium acetate, DL-sodium tartrate, L-sodium tartrate, potassium carbonate Sodium hydrogen carbonate, sodium carbonate, sodium lactate, DL-sodium malate, dipotassium hydrogen phosphate, disodium hydrogen phosphate, and the like.

  The kit preparation that can be used in the present invention is most preferably composed of a bicarbonate and an organic acid, each granulated in the presence of polyethylene glycol, and mixed and adjusted to a prescribed PH at a certain ratio in advance. , Powders, granules or compression-molded tablets having a pH of 6.0 to 9.5 when dissolved in water. By using this kit preparation in combination with a carbon dioxide dissolver, the carbon dioxide component quickly changes to bicarbonate ions, and it can be easily absorbed through the skin through contact with the body, promoting blood circulation and other health promoting effects. Is obtained.

  Furthermore, the preferable structural example of a kit formulation is explained in full detail.

  In the present invention, when the kit preparation is supplied as a tablet, in addition to the PH buffer material, a tablet containing sodium tetradecenesulfonate and / or sodium n- (normal) octanesulfonate as a particularly preferable compound may be mentioned. It is done. This compound is also a preferable compound for obtaining the persistence of foaming in the neutralization reaction. When the tablet according to the present invention is dissolved in hot water, micro-size foaming is performed, and the hot water after dissolution is dissolved. It is most preferable for maintaining the cleaning effect. The content of sodium tetradecenesulfonate and / or sodium n- (normal) octanesulfonate may be about 0.0005 to 0.01% by mass of the kit preparation according to the present invention.

  Citric acid or a mixture of citric acids and citric acid granules include anhydrous additives such as sodium carbonate, fragrances, pigments, surfactants, polyethylene glycol, and the like as desirable additives.

  For compression molding for producing tablets, a known compression molding machine can be used without any particular limitation. For example, a hydraulic press machine, a single shot tableting machine, a rotary tableting machine, a briquetting machine, etc. can be used. . The size of the punch used in this tableting machine or the like is preferably 7 mm or more when the punch is circular, and when the punch is a triangle or square, the diameter is 3 mm or more when converted to a circular punch. Those are preferred. The same applies to the thickness of the ridge. When obtaining a round tablet product, the diameter of the tablet is preferably 7 mm or more, and the thickness is preferably 3 mm or more. When the tablet is a triangle or quadrangle, the diameter and thickness are converted into a round tablet. It is more preferable that each of these is 7 mm or more.

  As described above, the tablet does not necessarily have to be a circle having a flat surface, and is preferably a solid material of 3 mm or more and preferably has a hardness of 5 kg or more. The shape of the tablet is not limited in any way, oval, tablet, or sphere.

  The present invention can also be configured so that the kit preparation contains a coloring component and / or a fragrance component. According to such a configuration, the user can easily grasp and feel the state in which the carbon dioxide component is mixed in the hot water. That is, according to the configuration containing the coloring component, it can be seen that the kit preparation is dissolved by being colored by the coloring component in which the hot water is dissolved, and according to the configuration containing the aromatic component, the hot water is dissolved. It can be seen that the kit preparation is dissolved by releasing the fragrance by the fragrance component.

As the coloring component that can be contained in the kit preparation of the present invention, a publicly known natural or synthetic coloring agent / coloring agent generally used for a bath agent can be used without any particular limitation.
In addition, as the fragrance component that can be contained in the kit preparation of the present invention, publicly known natural or synthetic fragrances and fragrances generally used for bathing agents, facial cleansers, soaps and the like can be used without any particular limitation. .

[Experimental example]
EXAMPLES Hereinafter, although an experiment example is given and this invention is demonstrated in detail, the aspect of this invention is not limited to these.

About the kit formulation used for the method and apparatus of the present invention, those having a pH of 6.0 to 9.5 after being dissolved in water and those outside the above PH value used as a comparative example were prepared by the following method.
In addition, the preparation of the tablets of Comparative Examples 1, 2, and 3 was performed by a general compression molding granulator in consideration of the preparation method of Example 2 described later.

  The carbon dioxide concentration was measured with an ion meter IM40S carbon dioxide electrode CE-235 manufactured by Toa Denpa Kogyo.

  Hereafter, it mentions from a comparative example before an Example.

Comparative Example 1
A 200 L normal bathtub was prepared, and tap water was added to make 41 ° C. hot water and then bathed for 10 minutes by a normal bathing method. The warming condition of the body temperature after 1 hour was measured by thermography.

Comparative Example 2
Using a commercially available air foaming device for tropical fish, a carbon dioxide gas cylinder is connected to the sintered foam used for this, and the flow rate of carbon dioxide is 3 L / min.
Put it in the water of 00L bath and submerge it, make it hot water with a temperature of 41 ° C, blow out and dissolve carbon dioxide for 30 minutes, bathe for 10 minutes while bubbling carbon dioxide gas, and then show the situation in thermography And measured the warmth of the body. The pH of this carbon dioxide blown hot water was 5.95.

Comparative Example 3
Carbonated springs were produced using the apparatus shown in FIG. 1 of JP-A-2002-66285. As the dissolver, a carbon dioxide gas dissolving module having the structure shown in FIG. 2 of the same publication and having a membrane area of 1.8 m ² was prepared.
The hollow fiber membrane used has a three-layer structure, an inner diameter of 200 μm, and the inner and outer layers each have a thickness of 20
The polyethylene porous membrane of μm and the intermediate layer are non-porous membrane segmented polyurethane membranes having a thickness of 0.5 μm.

The filter used was a 100 mesh non-woven fabric. The carbon dioxide gas dissolver (B) described in this publication is supplied with warm water of 41 ° C. at 15 L / min. At the same time, carbon dioxide gas whose pressure is adjusted by adjusting the pressure of the carbon dioxide gas from the carbon dioxide gas cylinder is supplied at a flow rate of 9 L / min. As a result, a carbon dioxide concentration of 1120 ppm in hot water was obtained. However, the pH value of this carbon dioxide-dissolved hot water was 4.89.

This carbonated spring was introduced into a 200 L bathtub and circulated, and the temperature was set to 41 ° C. while dissolving the carbon dioxide gas. The bath was taken for 10 minutes by a normal bathing method, and then taken and measured by thermography.

The measurement of the effect of warming during bathing was as follows.
Measurement of the skin temperature of the subject at the time of bathing In the room at 24 ° C, the surface of the whole body surface was taken with a thermography TVS500IS one hour after bathing in a bath with 41 ° C hot water. Sustainability was measured by 3 subjects and evaluated according to the following evaluation criteria.

◎: The entire thermographic shooting screen after 1 hour was red, and the body was recognized to be sufficiently warm. ◎◎ was more effective than ◎, and ◎◎◎ was further sustained.
○: The thermographic shooting screen after 1 hour is yellow, and a slightly warm effect is recognized.
Δ: The thermographic imaging screen after 1 hour is yellowish blue, the warming is very weak, and it is slightly warmer than entering normal bath water.
×: Thermographic photographs after 1 hour are mostly blue, and the effect of warming is the same as when bathing in normal bath water.

表１からもわかるように、炭酸ガス発泡溶解なしでは、１時間後のサーモグラフィーは真っ青で温まらない。例え焼結石を用いてもその効果は変わらない。一方、中空糸膜のようなメンブラン方式で高濃度に炭酸ガスを溶解した場合（比較例３）でも、入浴後1時間
後は、体の温まりは充分ではなかった。
なお、図３に示す如く、炭酸ガスの水への溶解度は、ヘンリーの法則から、４１℃では９５０ppm程度である。
Table 1

As can be seen from Table 1, the thermography after 1 hour is deep blue and does not warm without carbon dioxide foam dissolution. Even if sintered stone is used, the effect does not change. On the other hand, even when carbon dioxide gas was dissolved at a high concentration by a membrane system such as a hollow fiber membrane (Comparative Example 3), the body was not warm enough 1 hour after bathing.
As shown in FIG. 3, the solubility of carbon dioxide in water is about 950 ppm at 41 ° C. from Henry's law.

Carbon dioxide gas dissolution apparatus (A) using a tropical fish air foaming apparatus using the kit preparations (1) to (14) of the above composition in Comparative Example 2, or carbon fiber dissolution using a hollow fiber membrane used in Comparative Example 3 200 L of tap water flows into the bath where the vessel (B) is installed, dissolves carbon dioxide, dissolves the kit preparation, measures PH, and bathes at 41 ° C for 10 minutes while continuously blowing carbon dioxide. The body warming after 1 hour was photographed using thermography, and the results are shown in Table 2.

Table 2 Results using the carbon dioxide gas dissolution apparatus (A)

When the pH is acidic [outside the present invention (1) to (4)], even when bicarbonate or organic acid is present, the body warms even when carbon dioxide is supplied as a gas using sintered stone. Is not seen.
On the other hand, in the case of the kit preparation of the present invention [the present invention (5) to (14)], in any case, even with a simple carbon dioxide dissolving device of a sintered stone level, the body is sufficiently warmed and surpasses the conventional hollow fiber membrane. The effect was obtained.
In particular, in the presence of bicarbonate and citric acid [the present invention (7), (11) to (14)], an effect was obtained so that overwhelming warming of the body was obtained.

Table 3 Result of using carbon dioxide gas dissolving device (B) (When carbon dioxide is dissolved at high concentration by hollow fiber membrane)

As is clear from Table 3, as in Table 2, even when bicarbonate or citric acid was present, when PH was outside the range of the present invention, the warming of the body was not improved at all, but rather deteriorated.
However, when the kit preparation adjusted to PH of the present invention is added, the warmth of the body is surprisingly improved, and particularly good results are obtained when bicarbonate and citric acid are combined as in Table 2. In the presence of normal octane sulfonic acid, maximum body warming results were obtained.

Example 2
Granules PH adjusters consisting of bicarbonate and organic acid were obtained as kit formulations (15) to (20) by the following production method.

  460 kg of anhydrous sodium carbonate is added to the improved model of RED1200 manufactured by Matsuzaka Giken Co., Ltd., and the powder temperature is 45 ° C., 80 kg of polyethylene glycol # 6000 is added and granulated. When the powder temperature reaches 70 ° C., granulation is performed. This was indirectly cooled with cold water at 20 ° C. to obtain a granulated product A01.

Add 80 kg of citric acid, 4 kg of PEG # 6000, and 300 g of normal octane sulfonate to the granulated product A01 and mix. After mixing, each 60 g of this powder is individually packaged to form 10 bags of powder kit A (total 600 g) Stored.
The remaining powder was applied by Uplite Power Industry [Applied Power Japan Co., Ltd.] (former company name: Toyo Hydraulic Machinery Co., Ltd .: Model: SPLF-SPF-393), an oil press mold (manual tablet making machine) with a weight of 9 t and a diameter of 30 mm. Tablets of 15 mm were made to make 500 tablets of tablet kit A.
Further, 0.05 g of sodium tetradecenesulfonate was added, and 500 tablets of tablet kit B having a diameter of 30 mm and a thickness of 15 mm were similarly prepared.

Put 200 L of water in the bath where the carbon dioxide gas dissolving device (A) is installed, and add 1 bag (60 g) of powder kit A or 4 tablets of tablet kit A as shown in Table 4, After measuring PH at the time of dissolution, bathing was performed at 41 ° C. for 10 minutes while blowing carbon dioxide gas, and how the body warmed after bathing was photographed and measured by thermography, and the results are shown in Table 4 together with PH.

Table 4

As can be seen from the results in Table 4, the carbon dioxide gas that foams becomes finer and makes the body warming effect significantly improved when tableted, compared to the one-drug kit formulation with powder.
Also in this case, it was found that the body warming was maximized in the presence of sodium normal octane sulfonate and sodium tetradecene sulfonate.
In the case of sodium lauryl sulfonate, this effect is conspicuously reduced in the body warming. Therefore, this effect seems to be unique to sodium normal octane sulfonate and sodium tetradecene sulfonate.

Example 3
The following kit preparation was added and dissolved in 500 ml of the water tank using a spray-type device equipped with a small carbon dioxide gas cylinder, and gas was sprayed from the small carbon dioxide gas cylinder to the skin on the back side of the female subject's arm. That is, the forced melting device using hollow fibers / membranes as shown in FIG. 2 has two layers of hollow fibers as shown in (2a), and a large number of parallel hollow fibers as shown in (2b). It is a structure that injects and discharges tap water as an artificial carbonated spring, but using this structure, it is a structure that sprays carbon dioxide mist instead of water by application of a spray bottle, and is known as a sprayer for esthetics using carbon dioxide mist It is what.
Five subjects evaluated the smooth feeling of the skin, and the results are shown in Table 5 below as a sensitivity test.

×: No change in skin condition △: Slightly improved skin feel ○: Clearly improved smooth skin feeling ◎: Extremely improved and smooth skin feeling

Table 5

As you can see from Table 5,
It can be seen that even in the spray for esthetics using carbon dioxide mist, when bicarbonate or citric acid is present and PH is within the range of the present invention, the lively feeling and smoothness of the skin are remarkably improved. Thereby, the effect as a carbonate kit formulation for esthetics can be expected.
In addition, carbonic acid mist alone was not very effective, and even when citric acid alone or bicarbonate alone was used, no improvement in skin was observed in the case of PH outside the present invention.
