Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel sterilant,
In particular, the present invention relates to a sterilizing agent suitable for sterilizing a bath liquid and a method of using the same to sterilize a bath liquid. 2. Description of the Related Art With the advent of the so-called "health boom", various types of bath facilities, such as a health center and a health land, have gained in popularity. Have begun to be pointed out. In order to sterilize (disinfect) the bath liquid in such a bath facility, it is conceivable to use a disinfectant such as hypochlorite which is generally used for water treatment. However, the use of hypochlorite is problematic in terms of the generation of chlorine gas, trihalomethane, etc., and is particularly suitable for disinfecting bathing liquid because chlorine gas irritates eyes, nose and throat. Not. Further, such a bactericide is a medicinal bath (bath liquid containing a medicinal ingredient).
This is not preferable from the viewpoint of precipitating the medicinal component of the present invention and making it impossible to achieve the desired bathing purpose. In other words, the addition of a bactericide results in the disappearance of a unique aroma derived from medicinal ingredients such as Chinese herbal medicines and the feeling of heat during bathing, and the discoloration of the herbal medicine's unique color.
Decolorization impairs the commercial value itself as a medicinal bath. [0003] Many other sterilizing agents or germicides are available, but few satisfy the above-mentioned requirements for bathing solutions. Means for Solving the Problems and Their Effects
It has been found that when chlorine dioxide and malic acid are used in combination, the bath solution is effectively sterilized, and at that time, the medicinal component is not precipitated. [0005] Thus, the present invention provides a sterilizing agent characterized by containing malic acid and chlorine dioxide. It has been proposed that chlorine dioxide (ClO 2 ) itself be used as a disinfectant or disinfectant for tap water and wastewater. However, the use of chlorine dioxide alone has no effect on the sterilization of bathing liquids as targeted by the present invention. The inventor has developed an entirely new sterilant by combining chlorine dioxide and malic acid. [0007] The present invention provides a sterilizing agent composed of malic acid and chlorine dioxide. From another viewpoint, there is provided a method for sterilizing a bathing solution, which comprises adding malic acid and chlorine dioxide to the bathing solution. provide. In this case, 65-200 g of malic acid (powder) and 100-180 cc of chlorine dioxide (liquid) are added to 1 m 3 of the bathing solution.
Add 30-150 g and 120-140 cc of chlorine dioxide. Malic acid and chlorine dioxide may be added simultaneously or separately. An example of a preferable addition amount is 140 g of malic acid (powder) and 1 g of chlorine dioxide (liquid) per 1 m 3 of the bath liquid.
It is 30cc. Thus, the present inventor, when sterilizing medicinal water, by adding malic acid and chlorine dioxide, pH
Of about 6.8 (6.8 ± 0.2) is extremely effective. That is, it has been found that when the pH is higher than this, the sterilizing effect is reduced, and when the pH is too low, the precipitation of the medicinal component occurs. The present invention is practiced by directly adding malic acid and chlorine dioxide to a bathing solution, but with the above-mentioned composition (addition ratio) or, if necessary, concentration of either one. It is also carried out by transporting and selling as a sterilizing agent containing malic acid and chlorine dioxide, and adding the sterilizing agent to a bath solution on site. In preparing such a sterilant, malic acid and chlorine dioxide may be dissolved in a suitable solvent (eg, water) and other ingredients may be added, as appropriate, such as a suitable preservative. The malic acid used in the present invention is generally commercially available as DL-malic acid, but may be L-malic acid or D-malic acid. The chlorine dioxide used in the present invention is obtained from sodium chlorite and sulfuric acid, and is specifically produced as follows. This method is recommended by the American Public Health Association: 5.0 g of sodium chlorite is dissolved in 375 cm 3 of deionized water (without chlorine) in a flask. Add 1 cm 3 of concentrated sulfuric acid to 9 cm 3 of deionized water, mix and place in a funnel in the flask. Uniformly through the air in the flask, each 5 cm 3 every 5 minutes H 2 SO 4
Add. Continue blowing air for another 30 minutes and store the resulting liquid at 4 ° C. in a brown bottle. According to the present invention, when malic acid and chlorine dioxide are used, the bath solution can be effectively sterilized without irritating the eyes, nose and throat, and at that time, the precipitation of the medicinal component does not occur. Hereinafter, the present invention will be described with reference to Examples to further clarify the features of the present invention. Example 1 A bathing solution (white water) was sampled from a bathtub of a public bath that can accommodate about 300 people, and a lactose bouillon method (microorganism test method of “Hygiene Test Method” edited by The Pharmaceutical Society of Japan) As a result, 3000 coliforms per m 3 were detected. Therefore, according to the present invention,
DL-malic acid (obtained from Musashino Shoji Co., Ltd., trade name “Musashi malic acid”) and chlorine dioxide (obtained from Takasugi Pharmaceutical Co., Ltd.) were added in the amounts shown in Table 1 below, and the sterilization effect was examined. Was. For comparison, experiments were also performed using chlorine dioxide alone without using malic acid (Experiment A and Experiment B). [Table 1] Amount of malic acid and chlorine dioxide is the amount per bath liquid m 2. [0015] For each of them, the time from when malic acid and chlorine dioxide were added until the bath became negative (that is, the coliform group disappeared) was measured, and the result was as follows. Experiment A: 30 minutes; Experiment B: 3 hours; Experiment C: 2 hours; Experiment D: 30 minutes; Experiment E: 15 minutes; Experiment F: 15 minutes The group disappears but smells unfavorably. When the chlorine dioxide is reduced (experiment B), the bactericidal effect is reduced. According to the present invention, it has been found that when an optimal ratio of malic acid and chlorine dioxide is used, an excellent bactericidal effect can be obtained in a short time. Example 2 A bathing liquid (medicine water) was sampled from a bathtub of a public bath which can accommodate about 300 people. This bath liquid contains Fengxin, cinnamon, raw and the like as medicinal ingredients, and has a brownish color as a whole. In the initial analysis, this bath
20,000 coliforms per 3 were detected. To this, malic acid and chlorine dioxide were added at the ratios shown in Table 2 below. [Table 2] Amount of malic acid and chlorine dioxide is an amount per bath liquid m 3. In each case, after one hour, the pH was measured together with the detection of coliform bacteria, and the following results were obtained. In the case of Experiment F, the pH was 6.8, no coliform group was detected, and it was confirmed that effective sterilization was performed. In addition, the bathing solution retained brown color as a whole, and no precipitation of the medicinal component was observed. In the case of Experiment G, the pH was 6.5 and the coliform group was not detected, but the transparency was increased as a whole, and it was understood that a part of the medicinal component had precipitated. In the case of Experiment H, the pH was 7.2, and 1800 coliforms per m 3 were detected, indicating that sufficient sterilization was not performed.
