(57) [Summary] [PROBLEMS] To provide an oral cavity washing water capable of satisfying both safety and effectiveness. SOLUTION: The concentration of hypochlorous acid is 5 to 55 ppm. Hypochlorous acid having a concentration of 5 ppm or more has a strong bactericidal power and an effective stain removal ability, but a hypochlorous acid concentration of 55 ppm or less can be used for teeth and oral prostheses. It can be prevented from adversely affecting the system. |
