れているがいまだ十分ではなかった。The blood circulation promoting effect of carbon dioxide is greater as the concentration of carbon dioxide dissolved in cosmetics and packs (these are referred to as carbonic acid percutaneous absorption compositions in the present invention) is higher. . On the other hand, when only carbon dioxide gas is dissolved in water, the pH decreases as shown in FIG. 1, though it changes depending on the alkalinity of the water. Such an aqueous solution having a lowered PH has a strong irritation to the skin and is difficult to use as a cosmetic. To decrease PH, add PH adjuster
It is possible to set the ratio to 5 or more, but it is also considered that the additive has a bad effect for sensitive applications such as lotion. The first object of the present invention is to find a safe additive that is less irritating to the skin even if the pH is low. The second problem is that an aqueous solution containing carbon dioxide at a high concentration may escape into the air through the container during storage, or the carbon dioxide may immediately escape from the aqueous solution into the air when used at normal pressure. was there. The second problem was to solve these drawbacks. The second problem is disclosed in the prior art, for example, Japanese Patent Laid-Open No. 11-228834, but it has not been sufficient yet.

る水に溶解している遊離炭酸と考えて差し支えない。BEST MODE FOR CARRYING OUT THE INVENTION Carbon dioxide gas (CO2) is 20 ° C., 1
It has a solubility of 0.88 (ml / ml water) in water at atmospheric pressure (Chemical Encyclopedia). Carbon dioxide gas dissolved in water reacts with water to generate carbonic acid (H2CO3), and when the hydrogen ion concentration (PH) of water exceeds 6 and becomes high, the carbonic acid dissociates to hydrogen carbonate ions or carbonate ions. The free carbonic acid referred to in the present invention means that carbon dioxide gas is dissolved in water and exists in the state of carbon dioxide gas and carbon dioxide, and it changes depending on the alkalinity of water, but when PH is 6 or less, most of carbon dioxide gas is present. Exists in water as free carbonic acid. The blood circulation promoting effect is not seen with hydrogen carbonate ion or carbonate ion, and the state of carbon dioxide gas is necessary. As mentioned above, 1 atm of carbon dioxide is about 0.8 in 1 g of water.
8 ml is dissolved, but when this carbon dioxide gas is converted into mass, it becomes about 0.0016 g. That is, it is about 1600 ppm (mass basis). In the present invention, the mass of free carbonic acid dissolved in the composition for percutaneous absorption of carbonic acid is expressed in ppm. However, since the composition is mostly water, it is approximately dissolved in water constituting the composition. You can think of it as free carbon dioxide.

まれることを意味する。A method for producing a composition for percutaneous absorption of carbonic acid containing a predetermined amount of free carbonic acid of the present invention will be described later in detail. Carbon dioxide is directly pressurized and dissolved in water or an aqueous solution of the composition. Is. Therefore, the technology that aims at the stimulating action of carbon dioxide gas generated by the reaction of carbonate salt and organic acid, which is conventionally used as a bathing agent, and the blood circulation promoting action of carbon dioxide gas partially dissolved in water is essentially It is different.
Although carbon dioxide can be dissolved in water by such a chemical reaction, it is considered to be unsuitable for skin-sensitive applications such as lotion because the reaction product remains in water. In order to distinguish from these techniques, the aqueous solution of the composition is substantially free of bubbled carbon dioxide gas. The term “substantially” means that free carbonic acid once dissolved in water or an aqueous solution is included in the scope of the present invention as a bubble generated by changing the solubility of carbon dioxide gas due to stirring action, temperature change, pressure fluctuation and the like. means.

空気中に逃散してしまう。The blood circulation promoting action of the composition for percutaneous absorption of carbonic acid of the present invention can be examined as follows. Apply absorbent cotton or gauze thoroughly impregnated with the composition for percutaneous absorption of carbonic acid to the part with a white skin color, for example, the part of the inside of the arm where the sunlight is not relatively exposed or the knee part of the foot, for 5 to 10 minutes. Observe the condition of the skin before and after that. As a comparison, paste soaked pure water or tap water at the same time next to it. After a lapse of a predetermined time, remove the attached absorbent cotton etc. and observe the condition of the skin. The composition for percutaneous absorption of carbonic acid which has a blood circulation promoting effect makes the skin of the applied part red, and the comparative sample is the same as the state before the application, and therefore can be easily distinguished. That is, the blood circulation promoting action in the present invention means that the skin becomes red in such a test. When the blood circulation promoting action was examined in this manner, it was revealed that the composition exhibits a blood circulation promoting action when the free carbonic acid concentration in the composition is 300 ppm or more, preferably 500 ppm or more. The upper limit of the free carbonic acid concentration is around 2000 ppm, although it depends on the temperature at the time of use because the composition for transdermal absorption of carbonic acid is used under atmospheric pressure. It is possible to dissolve the above carbon dioxide gas in an aqueous solution according to Henry's law by injecting carbon dioxide gas of several atmospheres into the aqueous solution. However, since the atmospheric pressure is at the time of use, such an aqueous solution is not exposed to air. The carbon dioxide gas that is supersaturated by foaming due to the bubbles immediately escapes into the air.

た。FIG. 1 shows the relationship between the carbon dioxide concentration of carbonated water prepared by dissolving carbon dioxide in tap water and the pH. The concentration of carbon dioxide was measured using a carbon dioxide electrode. From this graph, the PH of carbonated water containing 300 ppm of carbon dioxide is 4.
It was 95. Therefore, in the present invention, 300 ppm or more of free carbonic acid is required as described above in order to function the blood circulation promoting effect, and for that purpose, the pH of carbonated water needs to be 5 or less, preferably 4.9 or less. On the other hand, carbonated water has a function of dissolving sebum of the human body, and when carbonated water having a PH of 5 or less is used as a lotion, it is difficult to use as it is because the sebum is dissolved and the face becomes tingling. It was In order to eliminate this drawback, the present inventors have studied various additives used in cosmetics, and found that trehalose is very effective. The reason why the combination of carbonated water and trehalose is superior is unknown, but it is assumed that trehalose can hold two molecules of water as crystal water and its unique hygroscopic property. is doing. In addition, trehalose has the effect of suppressing lipid spoilage, and is expected to have the effect of preventing age-related odors and body odors.
Use in cosmetics is also a preferable additive in this sense. The amount of trehalose contained in the composition for percutaneous absorption of carbonic acid is 0.1 wt% or more, preferably 0.5 wt% or more, more preferably 1 wt% or more. The upper limit is 10 wt% or less, preferably 7 wt, from the feeling of stickiness.
% Or less. When a carbonated percutaneous absorption composition containing free carbonic acid of 300 ppm or more and trehalose having a PH of less than 5 is used as a skin lotion, blood circulation is promoted together with the astringent action of the skin due to weak acidity, and this is combined with the unique action of trehalose, which has a negative effect on the skin. It has been discovered that a lotion having less irritation and a lot of excellent effects such as moisturizing feeling and whitening can be obtained.

ジェルは本発明ではゾルの範疇に入るものである。Next, the fifth invention relating to the composition for percutaneous absorption of carbonic acid of the second invention and the third invention and the method of using the same,
The preferred embodiment will be described as well. The description of the constituent elements overlapping the first invention described above will be omitted. Since the main purpose of the composition containing free carbonic acid of the present invention is to apply it to or apply it to a local part of the human body, it is preferable to select the viscosity appropriately depending on the use form. On the other hand, considering that the rate of escape of carbon dioxide gas into the air due to diffusion is inversely proportional to the viscosity of the composition, the higher viscosity is preferable.
5 dPa · s at least at room temperature, preferably 10 dPa
-S or more is preferable. Such adjustment of the viscosity can be performed by changing the type of polymer, the degree of polymerization and the concentration in the aqueous solution. In some cases, it is possible to change the viscosity by adding an inorganic or organic low molecular salt to the aqueous polymer solution. The gel referred to in the present invention refers to a state in which the viscosity is infinitely large and there is no fluidity, and the water-soluble polymer in the composition forms a three-dimensional stitch structure by intermolecular interaction and gels. Since the viscosity in the gel state is infinitely large, the escape of carbon dioxide gas from the composition is delayed, which is suitable for storing the composition. However, it is preferable to use the gel in the form of a sol because it is difficult to apply it because it has no fluidity during use. In the present invention, the gel does not exhibit fluidity as described above and its viscosity cannot be measured, which is different from what is generally called a gel in cosmetics. In terms of cosmetics, a state in which the viscosity is high and can be scooped with a fingertip is called a gel, but this gel has a viscosity that can be measured. In the present invention, so-called gels fall under the category of sol.

述のようにして求めることが出来る。In the present invention, the process of transition from sol to gel is called sol-gel transition, and the reverse is called gel-sol transition, and these transitions are collectively called phase transition. In the present invention, this phase transition is caused by a change in intermolecular interaction of the water-soluble polymer, and the change in intermolecular interaction is brought about by giving a physical or chemical action to the aqueous solution. It is preferable to give a temperature change as a physical action. A transition occurs depending on temperature, that is, the transition temperature is DS
It can be accurately determined by using an analytical instrument such as C or NMR, but in the present invention, it was simply determined by the following method. In the case of gelation or sol formation, it takes a long time to complete the transition because the viscosity of the entire system changes to lose fluidity or restore fluidity. In the present invention, the test tube containing the composition is observed in the constant temperature water bath while observing the temperature at which the fluidity, that is, the change in viscosity begins to occur, and the temperature at which the viscosity of the composition begins to change more than the temperature change is defined as the transition temperature. did. The chemical action can be performed by adding an additive that changes the solubility of the water-soluble polymer. In the present invention, it is preferable to add, as an additive, a low molecular weight salt that is well soluble in an aqueous solution. In this case, it is possible to confirm by the test tube method whether the temperature of the aqueous solution is constant, a predetermined amount of the additive is added, and the solution is left to stand for a while to gel or sol. Since the transition temperature differs depending on the amount of the additive, the transition temperature of the aqueous solution containing the predetermined amount of the additive can be obtained as described above.

ましくは３５℃以下に転移温度を示すものが好ましい。The above-mentioned transition temperature of the composition for percutaneous absorption of carbonic acid of the present invention is 0 ° C. or higher but lower than 45 ° C., preferably 0-40 ° C. from the viewpoint of use in the human body. A composition exhibiting a sol-gel transition in this temperature range is a composition exhibiting so-called thermal gelation characteristics. The composition of the present invention is produced by dissolving a water-soluble polymer in carbonated water or by dissolving carbon dioxide gas in an aqueous polymer solution. In any case, the solubility of carbon dioxide gas in water increases as the temperature decreases. Therefore, it needs to be performed at a low temperature. Further, in the case of an aqueous solution, it is preferable that the viscosity of the aqueous solution is lower because the diffusion rate of carbon dioxide gas into the aqueous solution becomes faster. Therefore, a polymer aqueous solution which exhibits a sol state at a low temperature and has a low viscosity can dissolve a high concentration of carbon dioxide gas in the composition. On the other hand, when the composition is stored, it has a high viscosity, preferably a gel state, from the viewpoint of escape of carbon dioxide gas. Also,
At the time of use, it is preferable that the sol state can be adjusted to an appropriate viscosity. It is preferable that these phase transitions can be easily carried out, and in the present invention, it is preferable to carry out by temperature, an additive such as a low molecular weight salt, or a combination thereof. If the transition temperature is high, it is necessary to raise the temperature of the composition in order to obtain a viscosity suitable for use, and carbon dioxide gas is likely to escape from the composition, which is not preferable. From this viewpoint as well, the transition temperature is lower than 45 ° C, preferably 40 ° C or lower. 3 is most preferable
It is a composition having a transition temperature near 7 ° C., and when applied in a sol state to a human body, gelation proceeds at body temperature and carbon dioxide gas is less likely to escape into the air, which is preferable. From a practical point of view, the lower limit temperature is preferably 0 ° C. or higher, which easily causes gelation or sol formation when stored at a refrigerator temperature. The situation is the same for a composition exhibiting a gel-sol transition, but it is necessary to carry out in a sol state at the preparation stage of the composition, that is, when carbon dioxide gas is dissolved in an aqueous solution, and the transition temperature is preferably low at 35 ° C. or lower. Those are preferable.

出来る。Methyl cellulose is well known as a water-soluble polymer which exhibits a sol state at low temperature and a gelling property at high temperature. As synthetic polymers, poly-N-isopropylacrylamide, poly-N-vinylacetamide, poly-N-vinylisobutyramide, copolymers of N-vinylisobutyramide and N-vinylacetamide, etc. are known. From the viewpoint of use in the human body, methylcellulose, which is a semi-synthetic polymer, is preferable. In the case of methyl cellulose, the transition temperature of its 2 wt% aqueous solution is 45 ° C. when measured by the method of the present invention, and it is preferable to add a low molecular weight salt in order to keep the transition temperature below 45 ° C. Such salts include sodium chloride, sodium sulfate, sodium carbonate,
Examples of the sodium salt include sodium hydrogen carbonate and sodium citrate. A preferred embodiment of the present invention uses a water-soluble polymer having such thermal gelation property to sufficiently dissolve carbon dioxide in an aqueous solution at low temperature and store it in a closed container,
If necessary, store in a refrigerator and leave the closed container in an atmosphere of 30-40 ° C during use to increase the viscosity associated with gelation, adjust the viscosity to an easy-to-apply state, and then open the container to remove the human body. Is to be applied locally. The thickening effect associated with gelation can also be achieved by adding the above-mentioned low molecular weight salt to the composition at the time of use. This method requires stirring in order to uniformly dissolve the salt in the composition for percutaneous absorption of carbonic acid, but care must be taken because carbon dioxide gas dissolved in the composition at that time escapes. By performing a salt which is easily dissolved or stirring at a low temperature for a short time, the viscosity change due to the phase transition of the composition can be achieved while minimizing the escape of carbon dioxide gas.

度が高く濃度が高いと相転移温度は高くなる。On the other hand, a composition for percutaneous absorption of carbonic acid which takes a gel state at a low temperature and shows a sol state at a high temperature can be stored in a gel state, so that the escape of carbon dioxide gas from the composition can be minimized, which is preferable. . For example, a composition for percutaneous absorption of carbonic acid comprising an aqueous solution of gelatin changes to some extent depending on the concentration of gelatin, but a 2 wt% aqueous solution causes gelation at about 25 ° C. or lower. Therefore, if carbon dioxide is dissolved in a sol state in the range of 25 to 30 ° C. and stored at 25 ° C. or lower, for example, in a refrigerator, a composition for percutaneous absorption of carbonic acid in which carbon dioxide hardly escapes can be obtained. At the time of use, the gel can be heated to 30 ° C. or higher to form a sol, which can be applied to a local area of the human body and used. Many water-soluble polymers that exhibit a gel-sol transition as the temperature rises are known. High-temperature soluble water-soluble polymers, starch, agar, agarose, guar gum, locust bean gum, xanthan gum, carrageenan, pectin, mannan, natural polymers such as dextran, hydroxypropylmethylcellulose, hydroxyethylmethylcellulose, carboxymethylcellulose, etc. Semi-synthetic polymers, polyvinylpyrrolidone, poly (meth) acrylic acid and its salts, polyacrylamide and its partial hydrolysates, synthetic polymers such as polyethylene oxide are exemplified, but the transition temperature is the polymerization of the polymer in an aqueous solution. It changes depending on the degree and concentration. Generally, the higher the degree of polymerization and the higher the concentration, the higher the phase transition temperature.

を図ることが出来る。Since the compositions according to the second and third aspects of the present invention contain carbon dioxide gas in an amount of 300 ppm or more, PH may drop to 5 or less. In that case, by adding trehalose as described in the first invention in addition to water, free carbonic acid and a water-soluble polymer, a composition for percutaneous absorption of carbonic acid having an excellent feeling of use can be obtained even if the pH is low, which is preferable. Further, if necessary, various additives such as the moisturizing component, the keratin softening agent, and the medicine described in the first invention can be added and used according to the purpose of use. The composition for percutaneous absorption of carbonic acid of the present invention contains carbon dioxide at a high concentration, and when applied to a local area of the human body as shown in the Examples below, reddening of the skin is observed even after 30 minutes and blood circulation is promoted. Since the rate of escape of carbon dioxide in the air is slow, it can be attached to an affected area where blood circulation is required to be healed.

It is difficult to apply a composition which has a low viscosity and flows and flows when applied to a human body or a composition which is gelled at room temperature as it is to a human body as it is. In such a case, a sheet-shaped support may be impregnated with the composition in a sol state, or a sheet-shaped material carrying the composition by coating may be attached to a local part of the human body for use. As the support, a flexible knitted fabric made of fibers, a woven fabric, a non-woven fabric, a felt-like material, a film made of a polymer, or the like can be used. In addition, in order to prevent the escape of carbon dioxide gas after being applied to a local area of the human body, or to prevent the composition from leaking to the outside,
It is also possible to use a composite support in which a support functioning as an impregnated layer of the composition and a support having a gas barrier function such as a polymer film are combined. The thickness of the sheet-like support is 5

粧料の量は必然的に少なくなってしまう。Finally, the sixth and seventh inventions concerning the method for producing the composition for percutaneous absorption of carbonic acid of the present invention will be explained. In the conventional manufacturing method, a cosmetic liquid such as lotion or lotion was put in a pressure resistant container, and the container was pressurized with carbon dioxide to manufacture a cosmetic containing carbon dioxide. This method seems to be simple as a manufacturing method at first glance, but it is a high-concentration product because the carbon dioxide gas to be injected under pressure is dissolved in water or alcohol in a container to dissolve a predetermined amount of carbon dioxide gas. In order to dissolve the carbon dioxide gas, it is necessary to increase the pressure of the carbon dioxide gas. Therefore, the container had to have a sufficient pressure resistant structure. Further, since the carbon dioxide gas is dissolved only from the surface of the liquid that comes into contact with the gas, it takes a long time to dissolve the high concentration carbon dioxide gas. The problem of time is that it is possible to carry out during the storage of the product because the dissolution gradually progresses if carbon dioxide gas is injected under pressure and left sealed and left to stand. It is necessary to secure enough space. Therefore, the amount of cosmetics occupied in the container is inevitably small.

得られる。In order to eliminate such drawbacks, the present inventors have proposed a method for transdermal absorption of carbon dioxide in which a step of dissolving carbon dioxide gas in the composition and a step of filling the obtained composition containing carbon dioxide gas into a container are separate steps. The method of making the composition was invented. In the step of dissolving carbon dioxide gas in the composition, it is preferable to prepare a composition raw material aqueous solution containing no carbon dioxide gas and bring the aqueous solution into contact with carbon dioxide gas in one step. In this case, it is preferable to degas the raw material aqueous solution in advance. Further, since the solubility of carbon dioxide gas in a liquid such as water is higher at lower temperatures, it is preferable to dissolve it at 30 ° C. or lower, preferably 25 ° C. or lower. Furthermore, it is preferable to use an apparatus in which the contact area between the carbon dioxide gas and the raw material aqueous solution is increased. It has been found that when the viscosity of the raw material aqueous solution is low, high concentration carbon dioxide can be dissolved in a short time by using a membrane type carbon dioxide dissolver. Such a membrane type carbon dioxide gas dissolver is disclosed, for example, in Japanese Patent No. 2810694 or Japanese Patent Laid-Open No. 7-
The one using the hollow fiber membrane disclosed in Japanese Patent No. 779 is preferable since it has a large contact area between gas and liquid and is efficient. When a membrane-type carbon dioxide dissolver is used, a sterile carbonic acid percutaneous absorption composition can be easily obtained by continuously providing a microfiltration device in the preceding stage or the subsequent stage to filter bacteria and foreign substances. .

容器である。On the other hand, in the case of a relatively viscous raw material composition containing a water-soluble polymer, the aqueous solution is placed in a pressure vessel such as an autoclave equipped with a stirrer and deaerated while stirring, and then carbon dioxide gas is removed. It can be pressed and dissolved. It is preferable to use a carbon dioxide gas cylinder for supplying carbon dioxide gas, but it is also possible to put solid carbon dioxide (dry ice) in an autoclave together with an aqueous solution and seal it. Further, as a device for continuously dissolving carbon dioxide in a high-viscosity aqueous solution, a method in which carbon dioxide is introduced in a wet wall device or a static mixer and dissolved and taken out while contacting or mixing with the aqueous solution is also a preferable method. Is. The pressure of carbon dioxide gas is preferably in the range of 0.1-0.5 MPa.

２０℃以下である。When the composition contains a water-soluble polymer exhibiting thermal gelation properties, it is preferable to disperse the polymer in water or an aqueous solution containing trehalose or a low-molecular salt at a temperature not lower than the gelation temperature. Below the gelation temperature, the dissolution rate of the polymer is high and the viscosity of the aqueous solution rises, making it difficult to uniformly dissolve the polymer even at a concentration of several percent. On the other hand, when the dispersion is carried out at the gelation temperature or higher, the polymer does not dissolve, so that the viscosity of the dispersion is low and a uniform dispersion can be obtained. A uniform aqueous polymer solution can be obtained by cooling the dispersion with stirring at a temperature below the gelation temperature. Since the solubility of carbon dioxide gas is higher at lower temperatures, this homogeneous solution can be charged into a carbon dioxide gas dissolving device in a cooled state to dissolve carbon dioxide gas, but it is preferable to cool carbon dioxide gas while cooling a uniform dispersion liquid having low viscosity. It is preferable to dissolve it. The cooling temperature is 30 ° C or lower, preferably 25 ° C or lower, more preferably 20 ° C or lower.

その濃度を定性的に判断した。The carbon dioxide concentration in the composition thus prepared can be determined by several methods. The carbon dioxide electrode method and the chemical titration method using standard reagents are effective for tap water and liquids with low viscosity, but cannot be used for high-viscosity compositions. In the present invention, in the case of a highly viscous composition containing a water-soluble polymer, its concentration was qualitatively determined from the mass of carbon dioxide gas absorbed in the composition in the carbon dioxide dissolving step and the blood circulation promoting action of the composition.

00 mPa · s) was dispersed. The dispersion solution was cooled to 30 ° C. (in this state, the polymer was not dissolved and was in a dispersed state), and the autoclave equipped with a stirrer having an internal volume of 1.5 L was filled and sealed. After degassing with a vacuum pump for 30 minutes while stirring in this state, the autoclave was cooled to 15 ° C. The vacuum line was switched to the carbon dioxide gas supply line, and 0.2 MPa carbon dioxide gas was supplied to the autoclave from the carbon dioxide gas cylinder. Carbon dioxide was dissolved over time and the pressure in the autoclave dropped, so carbon dioxide was appropriately supplied to return the pressure to 0.2 MPa. FIG. 2 shows the relationship between the mass of carbon dioxide gas absorbed in the aqueous solution and the time, which was obtained from the change in the gas space volume of the autoclave and the pressure change. It can be seen that 4 g or more of carbon dioxide gas was dissolved in 30 minutes. Carbon dioxide was dissolved for 4 hours, the autoclave was opened, and the aqueous solution was stored in a PET bottle. The aqueous solution foamed considerably at the same time when the autoclave was opened, and the dissolution of the polymer was not completely completed but was in a semitransparent state. PET
When the bottle was stored in the refrigerator overnight, the dissolution of the polymer proceeded to give a transparent solution. A part of this solution was placed in a test tube and the thickening behavior was investigated while raising the temperature in a constant temperature water bath.
A sharp increase in viscosity was observed from around ℃, so the sol-gel transition temperature was set to 30 ℃.

Based on this, we were able to achieve health promotion of facial skin, beauty (moisturized skin, whitening, elimination of acne such as acne), and improvement of cracks. Further, by utilizing the phase transition phenomenon of the water-soluble polymer, it is possible to obtain a composition for transdermal absorption of carbon dioxide which contains a high concentration of carbon dioxide and has little escape of carbon dioxide into the air at the time of use.
