Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathing agent, and more particularly to a bathing agent effectively used in a bathtub equipped with a bath water cleaning device.

[0002]

2. Description of the Related Art Various kinds of bathing agents are commercially available by adding them to hot water in a bath in order to enhance a hot bath effect. Conventionally commercially available bath agents include inorganic salts as warm bath agents, insoluble particles such as titanium oxide and calcium carbonate as clouding agents, oils as humectants, viscous substances such as gelatin as encapsulating agents, etc. , Various substances are mixed.

On the other hand, a bath water cleaning device as shown in FIG. 3 has been proposed for the purpose of enabling a comfortable bathing 24 hours a day. This bath water cleaning device pumps up the bath water 2 in the bathtub 1 by the circulation pump 5,
The cartridge filter 4 such as a bobbin type loaded in the filtration device 3 filters dirt such as hair and dirt, and the heater 6 heats it to an appropriate temperature. The aspirator 8 sucks ozone generated by the ozonizer 7 to sterilize it with ozone. , Activated stone tank 9
After activated by an activated stone 10 such as barley stone filled with, the bath is returned to the bath 1 again to keep the bath hot and clean at a constant temperature.

[0004]

In the bath water purifying apparatus as described above, activation treatment with activated stone or the like is performed, and in this treatment, minerals are eluted from the activated stone to give a warm bath effect. However, the elution amount of minerals is not so large in reality, and a sufficient warm bath effect cannot be expected.

Therefore, it is conceivable to use a commercially available bathing agent in order to enhance the hot bath effect, but various substances mixed in the bathing agent are adsorbed on the filter of the bath water cleaning device and the filter such as activated stone. There is a problem that it will be clogged and cause clogging.

Further, in the above-described bath water cleaning device, when sterilization is performed with ozone, unreacted ozone remaining in the bath water is released from the bath bath, and if a bather inhales this, an unpleasant odor is emitted. Will be sniffed, and may even impair your health.

Therefore, in reality, the amount of ozone used is suppressed as much as possible, and the sterilizing power is lowered. For this reason, when a large amount of bacteria is brought into the bath at a time, such as when the bather is dirty, incontinent during bathing, or when many people bathe at the same time or consecutively. It was difficult to sterilize this in a short time. In some cases, a sufficient bactericidal effect cannot be obtained even after several hours.

The lack of bactericidal power due to ozone causes
For example, as with normal water sterilization, it is possible to compensate by adding a chlorine-based bactericidal agent to the bath water, but the addition of a chlorine-based bactericidal agent causes discomfort to the bather due to a strong chlorine odor. It is not preferable because it may be given and may cause harm such as a sore throat and inflammation of the skin.

[0009]

Therefore, the present invention solves the above-mentioned problems of the prior art, and in particular, can be used by adding it to the bath water in the bathtub in which the bath water cleaning device is installed. It is an object of the present invention to provide a bathing agent having a novel composition that compensates for the insufficient hot bath effect and bactericidal power in the device, is completely harmless to the human body, and does not cause clogging of the filter material of the device. To aim.

That is, the bath agent according to the present invention comprises one or more germicides selected from the group of chemicals recognized as bath agents, such as the components listed in the cosmetic raw material standard, and inorganic salts as hot bath agents. At least.

As a bactericide, in order to avoid harm to the human body, it is listed as of May 1985 in the cosmetic raw material standard based on the Ministry of Health and Welfare Notification No. 322 of August 1985. 58
It is selected from the group of chemicals recognized as bath agents with 6 kinds of components.

In particular, any one of benzalkonium chloride, dipotassium glycyrrhizinate, and pyridoxine hydrochloride 1
It can be a simple substance composed of one kind or a mixture composed of two or more kinds thereof.

[0013]

[Function] Since the bathing agent contains a bactericidal agent together with a component having a warm bath effect, it prevents the growth of bacteria in the bathing water containing the bathing agent. In particular, when it is used by adding it to the bath water of the bathtub in which the bath water cleaning device is installed, a sufficient sterilization effect is exhibited in combination with the ozone sterilization effect of the device.

Since the bactericide contained in the bath agent is a harmless substance selected from the chemical group listed in the standard of cosmetic raw materials, it does not harm the human body.

[0015]

[Examples] First, benzalkonium chloride, methylparaben, dipotassium glycyrrhizinate and pyridoxine hydrochloride were selected from the group of chemicals listed in the standards for cosmetic raw materials, and tests were conducted to compare their bactericidal activity.

That is, each of the selected germicides is added to the bath water 200.
Predetermined amount per liter (0.02 grams, 0.05 grams,
0.10 gram) was added and left at a temperature of 42 ° C. for 24 hours. Then, 1 ml of the bath water to which each bactericide was added was added to each petri dish containing the dezoxycholate agar medium and the standard agar medium, and the bacteria were cultured at 37 ° C. for 24 hours. In this way, the number of coliform bacteria was examined in a petri dish containing the dezoxycholate agar medium in which the culture of the bacteria was completed, and the number of general viable bacteria was examined in the petri dish containing the standard agar medium.

The results are shown in Table 1. Although none of the bactericidal agents has a strong bactericidal power to completely sterilize general live bacteria, the bactericidal group which is particularly required for sterilization of bath water is It showed a sufficient bactericidal effect on sterilization.
In particular, benzalkonium chloride showed a remarkable bactericidal effect on coliform bacteria.

[Table 1] Regarding benzalkonium chloride, which showed the most remarkable bactericidal effect among the selected bactericides, the addition amount was different for 200 liters of bath water, and the sterilizing power at each addition amount was tested. Show.

[Table 2] As is clear from the results in Table 2, benzalkonium chloride has a sufficient bactericidal effect against coliform bacteria even when added in an amount of about 0.02 g in 200 liters of bath water, and benzalkonium chloride It was confirmed that the addition of a small amount of nitrogen can sufficiently compensate for the lack of sterilizing power when ozone sterilizing with a bath water cleaning device. Based on the above premise, a bath salt according to one example of the present invention was prepared with the following composition. Sodium sulphate (warm bath component) 34.00% by weight Sodium hydrogen carbonate (warm bath component) 58.60% by weight Borax (antiseptic and washing component) 6.00% by weight Guay (Phoenix) extract (antibacterial and moisturizing component) 0. 10% by weight Benzalkonium chloride (sterilizing component) 0.04% by weight Perfume (flavoring component) 0.80% by weight Pigment (coloring component) 0.20% by weight Water 0.26% by weight The bactericidal effect of this bath agent For confirmation, 200 liters of bath water immediately after bathing was subjected to cleaning treatment under the following test conditions for 2 hours, 4 hours, 6 hours and 8 hours, respectively, and 1 ml of the bath water after this treatment was sampled. The bacteria were cultured under the same conditions as in the case of examining the bactericidal effect of the bactericide, and the numbers of coliform bacteria and general viable bacteria were examined. In addition, in the cleaning process,
In each case, the bath water purifying apparatus shown in FIG. 3 was used. (A) Cleaning Treatment without Ozone Sterilization Ozone sterilization was stopped, and bath water was circulated through the purification device at a circulation rate of 15 liters / minute to perform filtration and activation treatment. (B) Cleaning treatment including ozone sterilization In the same manner as in (A) above, the bath water is circulated through the cleaning device at a circulation rate of 15 liters / minute to perform filtration and activation treatment, and at the same time, ozone concentration of 5 ppm Air was mixed into the bath water at a flow rate of 2 liters / minute for ozone sterilization treatment. (C) Cleaning treatment without ozone sterilization with addition of bathing agent of the example 50 g of the bathing agent of the above-described example was added, and the same cleaning treatment without ozone sterilization as in the above (A) was performed. (D) Cleaning Treatment Containing Ozone Sterilization with Addition of Bathing Agent of Example 50 g of the bathing agent of the above-described example was added to perform the same cleaning treatment including ozone sterilization as in (B) above. (E) Cleaning treatment without ozone sterilization together with addition of bathing agent of Comparative Example 50 g of bathing agent of Comparative Example as shown below was added to bath water to perform cleaning similar to the above (A) without ozone sterilization. Processed. Sodium sulphate (warm bath component) 34.00% by weight Sodium hydrogen carbonate (warm bath component) 59.00% by weight Borax (antiseptic and washing component) 6.00% by weight Guay (Phoenix) extract (antibacterial and moisturizing component) 10% by weight Fragrance (flavoring component) 0.80% by weight Dye (coloring component) 0.20% by weight Water 0.26% by weight (F) Cleaning treatment including ozone sterilization together with addition of bathing agent of comparative example 50 g of the bathing agent of the above example was added, and the same cleaning treatment including ozone sterilization as in (B) above was performed.
The results of the tests conducted under these conditions are shown as numerical values in Tables 3 and 4, and are also shown in graphs in FIGS. 1 and 2. In addition, Table 3 and FIG. 1 show the relationship between the cleaning treatment and the number of coliform bacteria under each of the above conditions, and Table 4 and FIG. 2 show the relationship with the number of viable bacteria in general.

[Table 3]

[Table 4] According to these test results, there is no bactericidal effect under the condition (A) in which the cleaning device was operated without ozone sterilization, and the bacteria grow over time, but it is remarkable under the condition (B) accompanied by ozone sterilization. It is understood that various bactericidal effects are observed, and the number of bacteria in the bath water contaminated by bathing rapidly decreases with time. On the other hand, under the conditions (C) and (D) in which the bath additive according to the example of the present invention was added, the ozone sterilization was stopped (C) as well as the case where the ozone sterilization was also performed (C). Even in the case, a remarkable bactericidal effect is recognized. Further, from the comparison of the test results under the conditions of (B) and (D), by adding the bathing agent of the example together with ozone sterilization, the bactericidal effect is further significantly improved, and bacteria, especially Escherichia coli, can be obtained in a short time. It can be seen that the number of groups has decreased to a benign level. From these, it is understood that the bath salts of the examples have a remarkable bactericidal effect.
On the other hand, under the conditions (E) and (F) in which the bathing agent was added in Comparative Example, almost the same results as in the cases (A) and (B) in which the bathing agent was not added were shown, No bactericidal effect due to the addition of the bath additive was observed. Further, a 6-month monitor bathing test was conducted while adding 20 g of the bathing agent of the above-mentioned example every day. During this period, abnormal occurrence of bacteria and clogging of the filter by the bathing agent did not occur, and there was no harm to the human body. I couldn't see it at all.

EFFECTS OF THE INVENTION According to the bath salt of the present invention, not only the hot bath effect similar to the conventional bath salts but also a remarkable bactericidal effect can be obtained. The bathing agent of the present invention does not cause clogging of the filter or the filter material of the bath water cleaning device, and therefore can be used by adding it to the bath water of the bathtub in which the cleaning device is installed. Thus, in combination with the sterilizing effect of ozone in the cleaning device, a sufficient sterilizing effect is exhibited. Therefore, the bath water does not breed bacteria and is always kept in a clean state, and it is possible to take a bath with a warm bath effect at any time and in the mood of a hot spring.
