Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides novel organic calcium that is effective for treating various diseases such as sensitivity to cold, neuralgia, pain from old injuries, and stiff shoulders, as well as for maintaining beautiful skin and improving the effect of hot baths. It relates to bath liquids.

Traditional medicine has been used in the past to include sulfur, sodium chloride, sodium hydrogen carbonate, borax, sodium iodide, sodium hydrogen phosphate,
Inorganic substances such as ammonium chloride and iron sulfate and menthol,
Camphor, seed coat, cinnabar, salicylic acid, olive oil,
Many artificial hot spring bath additives are known that contain organic substances such as enzymes as acids. In addition, products containing surfactants and chelate compounds have been proposed in order to enhance the therapeutic effect and hot bath effect, and to promote penetration into the skin (Special Publication No.
3699, Japanese Patent Publication No. 53-5382).

However, the anions contained in conventional artificial hot spring bath additives and natural hot springs are mainly inorganic ions such as bicarbonate ions (ocot-), chloride ions (CC-), and sulfate ions (SO4''-). Therefore, it has a strong effect on the human body, easily causing damage to body cells and inflammation of the skin, and interactions with various coexisting metal ions can cause side effects such as fatigue in the hot water. actually has the disadvantage of being harmful to the human body.

Problems to be Solved by the Invention The present invention aims to overcome the drawbacks of bath additives for natural hot springs and conventional artificial hot springs, and to provide a bath liquid that acts gently on the human body and has a high hot bath effect. It was done for a purpose.

Means for Solving the Problems As a result of various research conducted over many years on the relationship between dissolved components contained in hot springs and their effects, the present inventors have found that the cause of various disorders in hot springs is mainly due to the inappropriate amount of dissolved components contained in hot springs. This is due to excessive amounts of inorganic anions and alkali ions. Therefore, by converting these to organic carboxylic acid ions or other cations and adjusting the final concentration to a concentration equivalent to that of the donor solution, the previous problems can be eliminated. We have discovered that scales and naturally occurring corals and shells are suitable sources of cations in this case, and based on these findings, we have accomplished the present invention.

That is, the present invention dissolves coral powder or shell powder in an organic carboxylic acid, adds at least one selected from sodium chloride and potassium chloride as necessary, and then adjusts the pH to 2.5 to 6.0 with water. The present invention provides an organic calcium bathing solution that can be diluted to a concentration that shows the same concentration.

In the present invention, it is necessary to use coral powder or shell powder as a calcium source.

Since all of these powders are derived from the secretions of the animals themselves, the cationic composition therein poses no risk of causing any harm to the human body.

There are no particular restrictions on the types of corals and shells.
Although any substance can be used, coral coral,
Oyster shells, scallop shells, etc. are preferred.

Furthermore, the organic carboxylic acid used in the present invention may be either a -basic acid or a polybasic acid, such as acetic acid, citric acid, succinic acid,
Tartaric acid, oxalic acid, ascorbic acid, lactic acid, malic acid, etc. can be used, but citric acid is particularly preferred because it is colorless and odorless.

These organic carboxylic acids are used in the form of an aqueous solution with a concentration that can completely dissolve coral powder or shell powder. This concentration varies depending on the type of organic carboxylic acid and the type of powder to be dissolved, but is usually in the range of 5% to saturated concentration.

To prepare the organic calcium bath solution of the present invention, coral powder or shell powder is added to an aqueous organic carboxylic acid solution having an appropriate concentration and stirred to sufficiently dissolve the powder.

At this time, dissolution can be promoted by heating if necessary. The solution thus obtained, after filtering off undissolved solids, if any, and adding sodium chloride or potassium chloride, if desired, is prepared at an isoconcentration, i.e., at the same osmotic pressure as the body fluid. Dilute with water until the concentration is as follows. At this time, the p of the aqueous solution after dilution is
Adjust so that H is within the range of 2.5 to 6.0. In this way, by diluting the solution to the same concentration,
It is possible to prevent adverse effects on body cells due to imbalance of osmotic pressure.

If desired, organic acid salts such as sodium citrate, fragrances, colorants, surfactants, etc. can be added to the bath liquid thus prepared.

Next, an example of a system suitable for using the bath liquid of the present invention as a hot bath will be explained according to the accompanying drawings.

The figure is a system diagram showing one example of a bath equipment system for using the bath liquid of the present invention, in which coral powder or shell powder is mixed and dissolved in an organic carboxylic acid aqueous solution of a predetermined concentration in a dissolution tank 1. A solution is prepared using a pump 2, and the solution is sent to a storage tank 4 via a filter 3 and stored therein. Next, in the mixing tank 5, the organic calcium solution from the storage tank 4 and the sodium chloride or potassium chloride aqueous solution from the storage tank 6 are mixed, and water is introduced from the pipe 7 as necessary to maintain the same concentration of the supplied solution. While preparing the bath solution, the pH is adjusted within the range of 2.5 to 6.0. The bath liquid thus prepared is heated to a required temperature and then supplied to the bath [9] in the bathroom by a pump 8 as needed.

At this time, even if the bath temperature is constant, the humidity in the bathroom fluctuates due to factors such as the season, the weather, the influence of the atmosphere on the building structure, and the movement of air when entering and exiting. In order to fully demonstrate the effect of the hot air fan, it is necessary to keep the humidity and temperature in the bathroom as constant as possible.
It is advantageous to constantly blow and circulate fresh, dry air maintained at about 45 to 55°C.

This will not only make you feel refreshed but also promote sweating.
The hot bath effect is further promoted.

Effects of the Invention The organic calcium bath liquid of the present invention has a milder effect on the human body than natural hot springs or conventional artificial hot spring bath additives.
It does not cause skin damage or adverse effects on body cells, and it can provide an excellent hot bath effect.

Moreover, by using it in combination with a specific bath equipment system, the effect can be further enhanced. .

Next, 450°C hot water 44 (
Solution 3512 from storage tank 4 and solution 25Q from storage tank 6 were introduced into the tank while stirring, and after 5 minutes they were transferred to bathtub 8. Repeat this operation 4 times to obtain approximately 200
A bath solution of No. 012 was prepared. The Ca concentration of the bath liquid in the bathtub was 11058 ppm, the Na concentration was 470 ppm, the XK concentration was 516 ppm, the citric acid concentration was 7450 ppm, and the 1CQ concentration was 458 ppm. Moreover, pt+ was 4.8.

Example 4 200Q of 45° C. hot water was put into a 0.3-capacity dissolution tank equipped with a stirrer, and 9 hg of citric acid was added while stirring to completely dissolve it. Next, while stirring, 271 g of coral powder was gradually added and dissolved; thereafter, this solution was filtered through a filter to remove insoluble matter, to prepare about 20,012 g of organic calcium bath liquid. The calcium concentration in this bath liquid is 3980 ppm, citric acid concentration FK is about 40,
000 ppm, and the total molar concentration of calcium and citric acid was 0-30-3 l1/ff. Moreover, po was 3.4.

Example 5 In Example 1, 12 g of coral powder was dissolved using 50 g of malic acid instead of citric acid, the insoluble matter was removed from this solution, and 200 Q of warm water was added to prepare an organic calcium bath liquid. The calcium concentration in this bath is 25
ppm, the malic acid concentration was 222 ppm, and the pH of the bath solution was 4.2.

Reference Example An auxiliary bathtub made by Arjo was filled with bath liquid 180Q, and the effects of bathing were investigated over 3 days using 6 healthy young men as subjects.

That is, two hours after eating, the subject was kept at rest for about 30 minutes, then placed naked in a bathtub, bathed in a warm bath for 7 minutes at a water level that submerged the collarbone in a semi-recumbent position, and then left at rest for 15 minutes. . And the subject took a bath twice, and the second time was 2 times.
This was done after 4 hours had passed.

The bathing conditions at this time were as follows.

Room pressure: 954±15+ob Temperature: 71±5% Room temperature: 35±1.7°C Bath temperature: 38.5±0.7°C Measurements were made using Nihon Kohden Bedside Monitor Lifescope 11, OMP-7201K, NEC Saneisha Heart rate, oxygen intake, minute ventilation, respiratory rate, blood pressure, core body temperature, and buoyancy using Terumo aerobics, Processor 391-B, Terumo electronic blood pressure monitor, and Thermo 7-Einer Core Temp. went.

The results obtained using the organic calcium prepared in Example 3 as a sample are shown below.

■) Heart rate: It increased at the same time as taking a bath, with an increase rate of up to 51%, but it quickly returned to the resting level after taking a bath.

2) Oxygen intake, minute ventilation, and respiratory rate: They maintained almost their resting levels even during bathing, and no particular changes were observed.

3) Blood pressure: After bathing, systolic blood pressure is approximately 10 mmHg, diastolic blood pressure is approximately 2
A decrease in 01RIIIHg was observed and this value was maintained during bathing. After taking a bath, diastolic blood pressure returned to the value before bathing, but systolic blood pressure was approximately 10 a+mHg higher in some subjects.

4) Core body temperature: It rose immediately after taking a bath, and the rate of increase was highest in the front of the feet, forehead, and front of the body in that order.There was sweating even 20 minutes after taking a bath, and the temperature did not return to the value before bathing.

This is clearly different from the case of ordinary bathing water that does not contain organic calcium, and shows that it has a sustained heat retention effect.

5) Buoyancy: Compared to regular bathing, the buoyancy and relaxation were significantly greater, and the upper part of the body was more likely to be exposed above the water surface.
