Strongly acidic water of 5 or less has exfoliating ability. When strongly acidic water comes into contact with the skin, it reacts with organic substances on the skin and is immediately neutralized into water. Therefore, even if it remains on the skin, it does not damage the skin. Exfoliation with strongly acidic water is chemically performed and, unlike physical exfoliation, does not damage the skin. In a preferred embodiment of the present invention, the pH of the strongly acidic water for removing keratin exceeds 3, and the hypochlorous acid concentration is 0.5 ppm or more and 2 ppm or less. When the strongly acidic water contains hypochlorous acid having a concentration of 0.5 ppm or more, the exfoliation performance of the strongly acidic water is improved. In order to prevent skin damage due to hypochlorous acid when strongly acidic water containing hypochlorous acid remains on the skin, the hypochlorous acid concentration is based on the water purifier type examination standard of the Japan Water Works Association. Default value 2
It is desirable that the content is ppm or less. In a preferred aspect of the present invention, the strongly acidic water for removing keratin has a pH of 3 or less and a hypochlorous acid concentration of 0.5 ppm or more and less than 2 ppm. When the pH of the strongly acidic water becomes 3 or less, the ability to remove keratin from the strongly acidic water increases. In a preferred embodiment of the present invention, the strongly acidic water for removing keratin is produced by electrolyzing water to which saline is added. By electrolyzing the water to which the saline solution has been added, it is possible to obtain strongly acidic water for removing keratin having a desired pH and hypochlorous acid concentration. In a preferred embodiment of the present invention, the strongly acidic water for removing keratin is produced using an electrolyzer having a diaphragmless electrolyzer.
By using an electrolyzer having a diaphragmless electrolyzer, it is possible to obtain keratin-removing strongly acidic water having a desired pH and hypochlorous acid concentration.

The deterioration of the hollow fiber filtration membrane is prevented. The high-concentration saline solution stored in advance in the saline solution tank 7 is supplied to the water pipe 2b via the pump 8 and mixed with the tap water flowing through the water pipe 2b to be diluted. The diluted saline solution flows into the hollow fiber filtration membrane cartridge 5. The control unit 11 controls the drive power of the pump 8 according to the flow rate of the tap water detected by the flow rate sensor 3 and thus the flow rate of the tap water flowing through the water pipe 2b, and the high-concentration salt supplied to the water pipe 2b is controlled. The amount of water is controlled, and by extension, the salt concentration of the saline solution flowing into the hollow fiber filtration membrane cartridge 5 is controlled. The check valve 9 prevents tap water from flowing backward from the water pipe 2b to the salt water tank 7. Hollow fiber filtration membrane cartridge 5
The saline solution that has flowed into the tank is filtered by the hollow fiber filtration membrane stored in the cartridge 5, and the germs and foreign substances in the saline solution are removed. The saline solution from which bacteria and foreign substances have been removed flows into the diaphragmless electrolytic cell 6.

In the cathode plate 14, sodium ions (Na + ) and hydroxide ions (OH − ) existing in the saline solution are combined to generate caustic soda. As a result, alkaline water is generated near the cathode plate 14. The electrolysis power is controlled by the control unit 11, and the pH of the acidic water and the concentration of hypochlorous acid are controlled.

酸含有強酸性電解水が得られる。In the present diaphragmless electrolytic cell 6, the anode plate 1
Since the electrodes 3 and 15 and the cathode plate 14 are opposed to each other without a diaphragm, the distance between the electrodes is narrowed and the saline solution flowing between the first water passage 21 and the second water passage 22 formed between the electrodes. And the amount of hydroxide ions and hydrogen ions supplied to the electrode surface can be increased. As a result, in the present generator 1, it is possible to suppress the increase of the voltage applied between the electrodes and suppress the generation of hypochlorous acid, and to electrolyze the running water of the saline solution. It is possible to obtain strongly acidic electrolyzed water containing low concentration hypochlorous acid of 2 ppm or less. In the non-diaphragm type electrolytic cell 6, the electrode interval is sufficiently narrow, and the capacity of the saline distribution channel 23 is equal to that of the first water channel 2.
First, the horizontal cross section of the saline distribution channel 23 is sufficiently larger than the capacity of the first water channel 2 and the second water channel 22.
Since it is formed in a funnel shape that narrows toward the upstream ends of the first and second water passages 22, the saline solution that has flowed into the first water passage 21 and the second water passage 22 immediately forms a laminar flow. Therefore, the flowing layer of the strongly acidic electrolyzed water flowing along the first anode plate 13 and the second anode plate 15 is not mixed with the flowing layer of the strongly alkaline electrolyzed water flowing along the cathode plate 14. In the present diaphragmless electrolyzer 6, a flowing layer of the strongly acidic electrolyzed water flowing along the first anode plate 13 through the slit 13b formed in the first anode plate 13 in the downstream region of the first flow path. And the flowing layer of the strongly acidic electrolyzed water flowing along the second anode plate 15 is taken out through the slit 15b formed in the second anode plate 15 in the downstream region of the second flow path. Strongly acidic electrolyzed water containing low-concentration hypochlorous acid having an acid concentration of 2 ppm or less is obtained.

As for normal temperature water, normal temperature water of pH 7, strongly acidic water, pH
When the hands are washed in the order of 7 normal temperature water, the average value of the amount of keratin removal by the first washing with normal temperature water of pH 7 is p,
The removal angular mass of H7 with normal temperature water was used. For the other test waters, the average value of the removal angle mass by each washing in all the tests was taken as the removal angle mass by the test water. The relationship between the pH of the sample water and the removal angle mass obtained by the test is shown in FIG. From FIG. 10, it can be seen that when the pH of the sample water is 3.5 or less, the removal angle mass increases as compared to room temperature water having a pH of 7, and when the pH of the sample water is 3 or less, the removal angle mass particularly increases. Therefore, strongly acidic water having a pH of 3.5 or less is effective as a keratin remover, and strongly acidic water having a pH of 3 or less is particularly effective as a keratin remover. When strongly acidic water comes into contact with the skin, it reacts with organic substances on the skin and is immediately neutralized into water. Therefore, even if it remains on the skin, it does not damage the skin. Exfoliation with strongly acidic water is chemically performed and, unlike physical exfoliation, does not damage the skin. FIG. 11 shows the relationship between the concentration of hypochlorous acid and the removal angle mass obtained in the test. From FIG. 11, it can be seen that when the hypochlorous acid concentration of the sample water is 0.5 ppm or more, the removal angular mass increases as compared with the case where the hypochlorous acid concentration is 0 ppm. However, in order to prevent skin damage due to hypochlorous acid when strongly acidic water containing hypochlorous acid remains on the skin, the hypochlorous acid concentration is the water purifier type examination at the border of Japan Water Supply. It is desirable that the standard prescribed value is 2 ppm or less. The mechanism of keratin removal of strongly acidic water is unknown at present, but it is known that the strong oxidizing action of strongly acidic water destroys the -SS- bond of protein, and such oxidizing action is It is thought to have some effect on the keratin.

を得ることができる。As described above, strongly acidic water having a pH of 3.5 or less has the ability to remove keratin. When strongly acidic water comes into contact with the skin, it reacts with organic substances on the skin and is immediately neutralized into water. Therefore, even if it remains on the skin, it does not damage the skin. Exfoliation with strongly acidic water is chemically performed and, unlike physical exfoliation, does not damage the skin. When the strongly acidic water contains hypochlorous acid having a concentration of 0.5 ppm or more, the exfoliation performance of the strongly acidic water is improved. In order to prevent skin damage due to hypochlorous acid when strongly acidic water containing hypochlorous acid remains on the skin, the hypochlorous acid concentration is based on the water purifier type examination standard of the Japan Water Supply Border. It is desirable that the specified value is 2 ppm or less. When the pH of the strongly acidic water becomes 3 or less, the ability to remove keratin from the strongly acidic water increases. By electrolyzing the water to which the saline solution has been added, it is possible to obtain strongly acidic water for removing keratin having a desired pH and hypochlorous acid concentration. By using an electrolyzer having a diaphragmless electrolyzer, it is possible to obtain keratin-removing strongly acidic water having a desired pH and hypochlorous acid concentration.
