Description

[Technical field]

[0001] The present invention relates to a bathing method using carbonated microbubble mixed water having a carbonated microbubble effect. [Background technology]

[0002] Forming a mixture containing bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid into a foaming composition (solid material) by tableting or the like is applied to products such as detergents, bath additives, bath water cleaners, and pool disinfectants. These products (solid materials) have the advantage that when added to water, the ingredients react to generate carbon dioxide gas and dissolve quickly, while at the same time providing consumers with a comfortable feeling when used, thereby increasing the product value. In particular, bath additives (sometimes called bath salts) actively utilize the blood circulation promoting effect of the generated carbon dioxide gas.

[0003] There is a known technique for obtaining carbonated microbubble shower water by putting bath additives into a shower head instead of dissolving them in the water in a bathtub (see Patent Documents 1 to 3).

[0004] The technologies described in Patent Documents 1 to 3 claim that by taking a carbon dioxide microbubble shower without immersing oneself in the water of a bathtub, the carbon dioxide gas dissolved in the water released by the shower is absorbed through the skin, dilating the blood vessels, improving blood circulation and activating the metabolism of the entire body.

[0005] However, these conventional shower bathing techniques using carbon dioxide gas do not produce any clear and visible effects, but rather give the user a vague feeling that there is some effect, i.e., they only give the impression that there is some effect.

[0006] [Patent Document 1] JP 2008-241261 A [Patent Document 2] Japanese Patent Publication No. 62-283915 [Patent Document 3] JP 2007-289289 A Summary of the Invention [Problem to be solved by the invention]

[0007] The inventors continued to research technology that would allow one to effectively obtain the carbonated microbubble effect by taking a carbonated microbubble shower instead of immersing themselves in hot water in a bathtub. As a result, they discovered that by using a carbonated bath additive containing a specific component, the generated carbon dioxide gas component can be easily neutralized to bicarbonate ions by adjusting the pH value of the bath water, thereby infinitely increasing the concentration of bicarbonate ions absorbed through the skin.

[0008] Therefore, the present invention aims to provide a bathing method using carbonated microbubble water that can easily neutralize the generated carbon dioxide gas components into bicarbonate ions using the pH value of the bath water, thereby increasing the concentration of bicarbonate ions absorbed through the skin as much as possible, significantly accelerating blood flow and raising body temperature, thereby improving the effects of bathing on the inside, such as improving health and beauty, and by making a bath additive that does not contain bicarbonate ion sequestering substances, the carbonated microbubble mixed water obtained by dissolving this bath additive can be showered and sprayed onto the feet and / or armpits of the bather where body odor is a concern, thereby reducing body odor.

[0009] Similarly, the present invention provides a bathing method using carbonated microbubble water, which can improve the sleep state during sleep after bathing by showering the carbonated microbubble water obtained by dissolving the bath additives onto the whole body.

[0032] [Figure 1] FIG. 1 is a schematic diagram showing an embodiment of a bathing method using carbonated microbubble mixed water according to the present invention. [Diagram 2] FIG. 1 is a schematic diagram showing another embodiment of a bathing method using carbonated microbubble mixed water according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] Hereinafter, a bathing method using carbonated microbubble mixed water according to the present invention (hereinafter, sometimes simply referred to as a bathing method) will be described based on examples.

[0034] First, we will explain the bathing method of the first invention of the present invention. This is a technology that showers carbonated microbubble mixed water that combines the effects of carbonated spring bathing and microbubble effects, and by showering the bather's whole body or specific parts such as the feet and armpits with water mixed with carbon dioxide gas components and microbubbles, it is possible to obtain cleansing effects and health-promoting effects such as improved blood circulation.

[0035] In particular, the first invention of the present invention is a bathing method in which a bath agent storage section is provided for storing solid carbonated bath agent in a hot and cold water flow path, the carbonated bath agent stored in the bath agent storage section is dissolved by hot and cold water sent from a hose to a shower head to generate carbonated microbubbles and mix with the hot and cold water to produce carbonated microbubble mixed water, the carbonated microbubble mixed water is showered out from the hot and cold water outlet of the shower head, and the showered carbonated microbubble mixed water is showered in, the carbonated bath agent contains bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid, but does not contain a bicarbonate ion sequestering substance, the organic acid is at least one of citric acid, fumaric acid, succinic acid, and malic acid, and contains anhydrous sodium carbonate and / or anhydrous potassium carbonate, as well as sodium hyaluronate and hydrolyzed collagen, the hot and cold water discharged from the hot and cold water outlet of the shower head has a pH of 6.8 to 8.5, This bathing method using carbonated microbubble mixed water is characterized by reducing body odor by showering and washing the bather's feet and / or armpits where body odor is a concern. With this configuration, the carbon dioxide gas components generated can be easily neutralized to bicarbonate ions depending on the pH value of the bath water, and the concentration of bicarbonate ions absorbed through the skin can be increased to the maximum extent possible, significantly accelerating blood flow and raising body temperature, thereby improving the bathing effects such as health and beauty from the inside out. Furthermore, by using a bath additive that does not contain bicarbonate ion sequestering substances, the carbonated microbubble mixed water obtained by dissolving this bath additive can be showered and sprayed onto the bather's feet and / or armpits where body odor is a concern, thereby reducing body odor.

[0036] The time for showering the bather is preferably 8 to 10 minutes, and the temperature of the carbonated microbubble mixed water showered out is preferably in the range of 36 to 41° C. With such a showering time and temperature, the effect of showering out the carbonated microbubble mixed water can be extremely effectively achieved.

[0037] The diameter of the carbonated microbubbles released in the shower is preferably in the range of 1 to 100 μm. If the diameter is in this range, the effect of showering out the carbonated microbubble mixed water can be extremely effectively exhibited.

[0038] Furthermore, when the diameter of the bubbles of the carbonated microbubbles released in the shower is set to less than 1 μm, which is finer than the above-mentioned range of 1 to 100 μm, the obtained microbubbles are further fragmented, so that the effect of shower-releasing the carbonated microbubble-mixed water can be more effectively exhibited.

[0039] As shown in FIG. 1, the first aspect of the bathing method of the present invention uses a showerhead 1 used for shower discharge, which is connected to a hose 2 and has a bath additive storage section 3 for storing solid carbonated bath additives 4 inside the showerhead 1.

[0040] According to this configuration, the solid carbonated bath agent 4 can be dissolved efficiently and reliably by using the shower head 1 equipped with the bath agent storage unit 3. Therefore, when using the shower head 1, the effect of carbonated microbubble mixed water can be easily obtained by simply storing the carbonated bath agent 4 in the bath agent storage unit 3.

[0041] The shower head 1 equipped with a bath additive container may be any known or publicly used type, so long as it is configured to have a bath additive container 3 in at least one of the head and handle of the shower head 1.

[0042] Furthermore, the first invention of the present invention may be configured as shown in FIG. 2, in which a separate joint member 5 is connected between a shower head 1 used for shower discharge and a hose 2, and a bath additive storage section 3 for storing solid carbonated bath additives 4 is provided inside this joint member 5.

[0043] With this configuration, the benefits of carbonated microbubble mixed water can be easily obtained by simply applying the joint member 5 to an existing shower head 1 that has been abandoned at a hotel or sports gym at a travel destination, not limited to a favorite shower head 1 that is used daily.

[0044] In the embodiment in which the joint member 5 is interposed, any known shower head 1 can be used. A typical shower head 1 has a configuration including a hose 2 through which hot and cold water is supplied, a handle to which the hose 2 is connected, and a head that is integral with the handle and has hot and cold water ejection holes, but the handle and head are not limited to being integral, and may be formed separately and connected or joined to be integrated, or the head may be directly or indirectly connected to the handle so that the direction or angle can be changed, or the shower head may have various water ejection modes so that the desired water ejection mode can be selected according to mood or situation, or a shower head 1 having at least a head that has hot and cold water ejection holes, i.e., a shower head 1 having various configurations with different types, shapes, sizes, etc., may be used.

[0045] Next, the solid carbonated bath additive used in the bathing method of the present invention will be described.

[0046] The carbonated bath agent that can be used in the present invention can be any solid, regardless of its composition.It is not particularly limited in shape or size, and can be tablet, spherical, granular other than cubic.For example, the most preferred carbonated bath agent can be the one described in Japanese Patent No. 6268332 proposed by the present inventor, and is exemplified below.

[0047] After granulating bicarbonate with polyethylene glycol (hereinafter sometimes referred to as "PEG") or the like, an organic acid (particularly citric acid, succinic acid, malic acid, fumaric acid) or the like is mixed or granulated with PEG, and each is mixed under conditions within a certain ratio, and the excipient of the present invention is added and formed into a tablet by compression molding. By designing the pH just after the tablet is dissolved to be in the following range, when water penetrates the tablet, it reacts to vigorously, uniformly and continuously foam carbon dioxide gas, and the generated carbon dioxide gas bubbles can be generated for a long time as fine micro-sized carbon dioxide gas, and the tablet continues to foam micro-sized bubbles until it is completely dissolved, and the bubbles are neutralized in water before volatilizing into the air, dissociated into bicarbonate ions, and a high concentration of bicarbonate ions is dissolved. The pH of the water is designed to be 5.5 to 9.0, and when it is 6.8 to 8.5, the effects of cleansing effect and health promotion effects such as promoting blood circulation are maximized.

[0048] Furthermore, since the bicarbonate mixture is a granulated product prepared by coating with PEG using a fluidized bed, the above-mentioned effects, such as a continuous and uniform reaction in the tablet, are greatly exhibited.

[0049] In addition, the tablet hardness is preferably 15 kg or more, more preferably 25 kg or more, and even more preferably 30 kg or more, so that the chlorine neutralizing compound can react continuously and stably with the tablet. It is preferable that the tablet is molded to a high hardness so that the chlorine neutralizing reaction inside the tablet is suppressed and the part where the tablet dissolves can quickly remove chlorine in hot water. The higher the chlorine removal effect, the greater the health benefits such as improved blood circulation and increased body temperature can be achieved even when taking a shower.

[0050] Furthermore, the tablet friability is preferably 10.0 wt% or less, more preferably 5.0 wt% or less, and even more preferably 3.0 wt% or less, so that the chlorine neutralizing compound can continue to react stably and the efficiency of the chlorine neutralization reaction inside the tablet can be maximized, and health-promoting effects such as improved blood circulation and increased body temperature can be achieved even when taking a shower.

[0051] For the compression molding to prepare the carbonated bath agent tablets preferably used in the present invention, a known compression molding machine can be used without any particular restrictions, for example, a hydraulic press, a single shot tablet press, a rotary tablet press, a briquetting machine, etc. can be used. The size of the punch used in this tablet press, etc., is preferably 7 mm or more in diameter when the punch is circular, and preferably 7 mm or more in diameter when the punch is triangular or rectangular. The same applies to the thickness of the punch. When obtaining a circular tablet product, the diameter of the tablet is preferably 7 mm or more, more preferably 10 mm or more, and the thickness is also 7 mm or more, preferably 10 mm or more, and when a triangular or rectangular tablet is obtained, the diameter and thickness are each preferably 7 mm or more, particularly 10 mm or more, when converted to a circular tablet.

[0052] Carbonated bath additive tablets do not necessarily have to be circular with a flat surface; as long as they are solid objects of 7 mm or more, they may be oval, tablet-shaped, or spherical, with no limitations on their shape.

[0053] It is preferable to slowly generate micro-sized bubbles in tablets of the above-mentioned hardness and friability and of a certain size or larger, and to dissolve carbon dioxide gas in hot water more efficiently; therefore, the hardness is 15 kg or more, preferably 25 kg or more, and particularly preferably 35 kg or more; the friability is 10.0 wt% or less, preferably 5 wt% or less, and particularly preferably 3 wt% or less; and the diameter and thickness are particularly preferably 10 mm or more, so that the generation of carbon dioxide gas in the tablet occurs more effectively, the dissolution of carbon dioxide gas in water is efficient, and the diameter of the bubbles becomes fine, making this a preferred carbonated bath agent for use in the present invention. In other words, by making the diameter of the bubbles less than 1 μm, even better effects can be obtained than in the experimental examples below.

[0054] Next, experimental example 1 based on the bathing method of the first invention will be described.

[0055] [Experimental Example 1] An experimental evaluation of the reduction in body odor was carried out by 11 male subjects.

[0056] [Table 1]

[0057] As shown in Table 1, the average age of the 11 subjects (male) was 43.6±8.9 years old. They were all Japanese men aged between 30 and 59 years old at the time of consenting to the experiment.

[0058] The entry criteria for subjects (self-report) were that they were concerned about body odor from their feet, armpits, etc., or had been told they had body odor, and were able to consent to having their armpits and soles of the feet exposed to have the odor measured.

[0059] The exclusion criteria for subjects (self-reported) were: those with skin diseases, those participating in other clinical trials, those who may have allergic reactions to the test product materials, those who are visiting a hospital or taking medication, Those currently undergoing treatment, and those with underlying diseases (diabetes under medical treatment or diabetes with complications, chronic respiratory disease, chronic heart disease (including high blood pressure), chronic kidney disease, chronic liver disease (excluding fatty liver and chronic hepatitis), chronic blood disease (excluding iron deficiency anemia), neurological or neuromuscular disease associated with immune abnormalities, chromosomal abnormalities, severe physical and mental disabilities (a condition in which severe physical disabilities overlap with severe intellectual disabilities)).

[0060] Regarding the management of subjects, the living environment (sleep, diet, general lifestyle) was maintained the same as before the start of the experiment.

[0061] The solid carbonated bath additive used in the experiment was that described in Japanese Patent No. 6268332, which was previously proposed by the inventor. As a specific configuration, the tablet (1) described in paragraphs

[0107] to

[0109] of the patent was used. One tablet of this carbonated bath additive was placed in the bath additive storage section of a shower head (product name: Bicarbonate Crystal Ion Shower, manufactured by Hot Album Carbonated Spring Tablet Co., Ltd.).

[0062] The experimental conditions were as follows: target areas: left sole and left armpit, water temperature: 40°C, time for showering the target areas: 8-10 minutes. First, the odor of the target areas (left sole, left armpit) of each subject was measured before the shower, and then the odor of the target areas after the shower had been sprayed on the target areas for 8-10 minutes was measured and compared. The results are shown in Tables 2-5.

[0063] [Table 2]

[0064] [Table 3]

[0065] [Table 4]

[0066] [Table 5]

[0067] As shown in Tables 2 to 5, the results of Experimental Example 1 show that odor improvement can be achieved by taking a shower using the bathing method according to the first aspect of the present invention.

[0068] In particular, according to the present invention as shown in claim 2, since the structure has an internal volume that allows free movement, including rotation, of the carbonated bath additives contained therein, it has been confirmed that a greater body odor removal effect and health promotion effects such as improved blood circulation can be obtained.

[0069] For the odor of the left sole, 10 out of 11 people showed an improvement of about 10% or more, and in particular, for three of those 10 people (subject numbers 1353971, 1491430, and 1502319), the odor was reduced to about two-thirds to half, and for two more people (subject numbers 1325628 and 1427882), the odor was significantly reduced to less than one-third. For the odor of the left armpit, 9 out of 11 people showed an improvement of about 10% or more, and in particular, for three of those nine people (subject numbers 848850 and 1491430), the odor was reduced to about two-thirds to half, and for one more person (subject number 1427882,) the odor was significantly reduced to about one-tenth.

[0070] Statistical analysis of odor measurement results of the left sole before and after shower discharge using paired t-test showed that the odor was 119.4±43.8 before shower discharge and 85.8±51.4 after shower discharge, and was -33.6 after shower discharge compared to before shower discharge, showing a significant difference after shower discharge (P<0.001). Statistical analysis of odor measurement results of the left armpit before and after shower discharge using paired t-test showed that the odor was 113.2±42.1 before shower discharge and 91.8±48.8 after shower discharge, and was -21.4 after shower discharge compared to before shower discharge, showing a significant difference after shower discharge (P=0.014).

[0071] In the above-mentioned Experimental Example 1, an experiment was conducted with the only difference being that tablets (2), (3) and (4) of the same patent publication were used, and the same odor improving effect as the present invention was obtained. In addition, in the above-mentioned Experimental Example 1, a similar experiment was conducted by removing vitamin C·Na, sodium hyaluronate, hydrolyzed collagen, caprylysulfonic acid and sodium olefin (C14-16) sulfonate, and the same effect was obtained. Furthermore, in the above-mentioned Experimental Example 1, a comparison was made between the case where the diameter of the carbon dioxide microbubbles released by shower is 1 μm or more and the case where it is less than 1 μm, and it was confirmed that the technology of the present invention can obtain a higher effect when the diameter is less than 1 μm.

[0072] In particular, according to the present invention as set forth in claim 2, since the internal volume allows free movement, including rotation, of the carbonated bath additive contained therein, it has been confirmed that a higher body odor removal effect and health promotion effect such as blood circulation promotion effect can be obtained. In other words, it has been confirmed that the odor improvement effect shown in Table 2-5 is improved by 20 to 25%.

[0073] Next, we will explain the bathing method according to the second aspect of the present invention. This is a technology that showers out carbonated microbubble-mixed water, which has both the effects of carbonated spring bathing and microbubble effects, and allows the bather to shower the whole body or specific parts of the body, such as the feet and armpits, with water mixed with carbon dioxide gas components and microbubbles, thereby providing a cleansing effect and health-promoting effects such as improved blood circulation.

[0074] In particular, the second invention of the present invention is a bathing method in which a bath agent storage section is provided for storing solid carbonated bath agent in a hot and cold water flow path, the carbonated bath agent stored in the bath agent storage section is dissolved by hot and cold water sent from a hose to a shower head to generate carbonated microbubbles and mix with the hot and cold water to produce carbonated microbubble-mixed water, the carbonated microbubble-mixed water is showered out from the hot and cold water outlet of the shower head, and the showered carbonated microbubble-mixed water is showered out. The carbonated bath agent contains bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid, but does not contain a bicarbonate ion sequestering substance, the organic acid is at least one of citric acid, fumaric acid, succinic acid, and malic acid, and contains anhydrous sodium carbonate and / or anhydrous potassium carbonate, as well as sodium hyaluronate and hydrolyzed collagen, the hot and cold water discharged from the hot and cold water outlet of the shower head has a pH of 6.8 to 8.5, This bathing method using carbonated microbubble water is characterized in that the carbonated microbubble mixed water is continuously showered onto the entire body of the bather, thereby improving the sleep state during sleep after bathing.With this configuration, the carbonated microbubble mixed water obtained by dissolving the carbonated bath additives is showered onto the entire body, thereby improving the sleep state during sleep after bathing.

[0075] The shower head equipped with a carbonated bath additive storage section, the joint member equipped with a carbonated bath additive storage section that allows the use of an existing shower head, and the solid carbonated bath additives used in the second invention are configured in the same manner as in the first invention described above.

[0076] The time for showering the bather is preferably 8 to 10 minutes, and the temperature of the carbonated microbubble mixed water showered out is preferably in the range of 36 to 41° C. With such a showering time and temperature, the effect of showering out the carbonated microbubble mixed water can be extremely effectively achieved.

[0077] The diameter of the carbonated microbubbles released in the shower is preferably in the range of 1 to 100 μm. If the diameter is in this range, the effect of showering out the carbonated microbubble mixed water can be extremely effectively exhibited.

[0078] Furthermore, when the diameter of the carbonated microbubbles released in the shower is set to less than 1 μm, which is finer than the above-mentioned range of 1 to 100 μm, the obtained microbubbles are further fragmented, so that the effect of shower-releasing carbonated microbubble-mixed water can be extremely effectively and further enhanced.

[0079] Next, a second experimental example based on the bathing method of the second invention will be described.

[0080] In the following Experimental Example 2, the degree of improvement in the sleep state after bathing is evaluated based on the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), thermography (histogram temperature analysis), or laser blood flow measurement. By applying such an evaluation method, the degree of improvement in the sleep state after bathing can be numerically and specifically grasped.

[0081] [Experimental Example 2] Improvement in sleep state was experimentally evaluated by 33 female subjects.

[0082] [Table 6]

[0083] As shown in Table 6, the average age of the 33 subjects (female) was 48.5±7.1 years old. The ages of the subjects at the time of consenting to the experiment were between 30 and 59 years old, and all subjects were Japanese women.

[0084] The exclusion criteria for subjects (self-reported) were: those with skin diseases, those participating in other clinical trials, those at risk of developing allergic symptoms from the test product materials, those receiving outpatient treatment, medication or other treatment, and those with underlying diseases (diabetes under medication or diabetes with complications, chronic respiratory disease, chronic heart disease (including high blood pressure), chronic kidney disease, chronic liver disease (excluding fatty liver and chronic hepatitis), chronic blood disease (excluding iron deficiency anemia), neurological or neuromuscular disease associated with immune abnormalities, chromosomal abnormalities, severe physical and mental disabilities (a condition in which severe physical disabilities and severe intellectual disabilities overlap)).

[0085] Regarding the management of subjects, the living environment (sleep, diet, general lifestyle) was maintained the same as before the start of the experiment.

[0086] The solid carbonated bath additive used in the experiment was that described in Japanese Patent No. 6268332, which was previously proposed by the inventor described above. Specifically, the tablet described in Experimental Example 1 was used. One tablet of this carbonated bath additive was placed in the bath additive storage section of a shower head (product name: Bicarbonate Crystal Ion Shower, manufactured by Hot Album Carbonated Spring Tablet Co., Ltd.).

[0087] The experimental conditions were as follows: area to be showered: whole body, shower water temperature: 40°C, time spent bathing in the hot water discharged from the shower per bath: 8-10 minutes. A comparison was made between the sleep state before the start of the experiment and after four weeks of showering using the bathing method of the second invention of the present invention. The results are shown in Tables 7 to 25.

[0088] The evaluation based on the Pittsburgh Sleep Quality Index (PSQI) is shown in Tables 7, 8, and 9. Table 7 shows the transition values, Table 8 shows the score discrimination criteria, and Table 9 shows the transition of answers.

[0114] Tables 25 and 26 show the individual data from the subjective symptom questionnaire.

[0115] [Table 25]

[0116] [Table 26]

[0117] As shown in Tables 7 to 25, the results of Experimental Example 2 show that taking a shower according to the bathing method of the second aspect of the present invention improved the state of sleep.

[0118] In particular, improvements were seen in sleep quality, time to fall asleep, sleep duration, sleep efficiency, improvement in difficulty sleeping, and improvement in difficulty waking during the day. Furthermore, it was found to be effective in improving loss of appetite, poor bowel movements, lack of motivation to be active, fatigue, lack of concentration, poor judgment, lack of energy and motivation, cold hands and feet, swelling of hands and feet, body odor, dry mouth and eyes, stomach and abdominal pain, headaches in the hands, neck and shoulder pain, chest and back pain, lower back pain, joint pain, scalp odor, scalp dirt, dry hair and poor texture, difficulty in combing and running fingers through hair, split ends and hair loss, dry skin, shiny skin, sagging skin, rough skin, poor skin texture, dull skin, and poor makeup application.

[0119] In the above-mentioned Experimental Example 2, when the same experiment was performed by removing Vitamin C·Na, sodium hyaluronate, hydrolyzed collagen, caprylysulfonic acid, and sodium olefin (C14-16) sulfonate, substantially the same effect was observed. Also, as in the above-mentioned Experimental Example 1, when comparing the case where the diameter of the carbonated microbubbles is 1 μm or more with the case where it is less than 1 μm, it was confirmed that the technology of the present invention can obtain a higher effect when the diameter is less than 1 μm.

[0120] Next, we will explain the bathing method according to the third invention of the present invention. This is a technology that showers out carbonated microbubble mixed water, which has both the effects of carbonated spring bathing and microbubble effects, and allows the bather to shower the whole body or specific parts such as the feet and armpits with water mixed with carbon dioxide gas components and microbubbles, thereby achieving cleansing effects and health-promoting effects such as improved blood circulation.

[0121] In particular, the third invention of the present invention is a bathing method in which a bath agent storage section is provided for storing solid carbonated bath agent in a hot and cold water flow path, the carbonated bath agent stored in the bath agent storage section is dissolved by hot and cold water sent from a hose to a shower head to generate carbonated microbubbles and mix with the hot and cold water to produce carbonated microbubble mixed water, this carbonated microbubble mixed water is showered out from the hot and cold water outlet of the shower head, and the shower is bathed in the carbonated microbubble mixed water, wherein the carbonated bath agent contains bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid, but does not contain a bicarbonate ion sequestering substance, the organic acid is at least one of citric acid, fumaric acid, succinic acid, and malic acid, and contains anhydrous sodium carbonate and / or anhydrous potassium carbonate, the hot and cold water discharged from the hot and cold water outlet of the shower head has a pH of 6.8 to 8.5, This is a bathing method using carbonated microbubble mixed water, characterized in that the chlorine content concentration of the carbonated microbubble mixed water released in the shower is reduced by removing chlorine contained in the hot water supplied through a hose. With this configuration, the chlorine content concentration of the carbonated microbubble mixed water released in the shower can be reduced by removing chlorine contained in the hot water supplied through a hose.

[0122] The shower head equipped with a carbonated bath additive storage section, the joint member equipped with a carbonated bath additive storage section that allows the use of an existing shower head, and the solid carbonated bath additives used in the third invention are configured in the same manner as in the first invention described above.

[0123] The time for showering the bather is preferably 8 to 10 minutes, and the temperature of the carbonated microbubble mixed water showered out is preferably in the range of 36 to 41° C. With such a showering time and temperature, the effect of showering out the carbonated microbubble mixed water can be extremely effectively achieved.

[0124] The diameter of the carbonated microbubbles released in the shower is preferably in the range of 1 to 100 μm. If the diameter is in this range, the effect of showering out the carbonated microbubble mixed water can be extremely effectively exhibited.

[0125] Furthermore, when the diameter of the carbonated microbubbles released in the shower is set to less than 1 μm, which is finer than the above-mentioned range of 1 to 100 μm, the obtained microbubbles are further fragmented, so that the effect of shower-releasing carbonated microbubble-mixed water can be extremely effectively and further enhanced.

[0126] Next, a third experimental example based on the bathing method of the third invention will be described.

[0127] Public tap water heated to 40℃ (Tokyo Metropolitan Government Bureau of Waterworks: water pressure 3.5kgf / cm 2 When DPD (N,N-diethyl paraphenyl diamine) was added to the solution until it turned colored, the solution turned a light reddish purple. This indicates that there is residual chlorine in the warmed solution. When the residual chlorine is gone, the color disappears and the solution becomes transparent, allowing the state of chlorine neutralization to be determined.

[0128] Using the above 40°C pale reddish purple solution, the absorbance at a wavelength of 554 nm was measured using an absorption spectrometer (Shimadzu Corporation). The chlorine content of the carbonated microbubble mixed water released into the shower, obtained by the bathing method of the third invention of the present invention, was evaluated based on the relative value taken as 100, where the absorbance of the 40°C solution released into the shower without using any carbonated bath additives was taken as 100.

[0129] The solid carbonated bath agent contained in the bath agent storage unit in the shower head was the same as that used in the above Experimental Examples 1 and 2. When the absorbance of the solution released in the shower was measured, it was found to be less than one tenth of that. In other words, according to the configuration of the bathing method of the third invention of the present invention, the chlorine content of the carbonated microbubble mixed water released in the shower can be significantly reduced.

[0130] In addition, when the same experiment was performed without the vitamin C·Na, sodium hyaluronate, hydrolyzed collagen, caprylysulfonic acid, and sodium olefin (C14-16) sulfonate in the above-mentioned Experimental Example 3, substantially the same effect was observed. Furthermore, as in the above-mentioned Experimental Example 1, when the diameter of the carbonate microbubbles was compared between 1 μm or more and less than 1 μm, it was confirmed that the technology of the present invention can obtain a higher effect when the diameter is less than 1 μm.
