    Abstract: An apparatus and method for electrochemically generating and using an aqueous solution containing chlorine dichloride and a metal hypochlorite, such as sodium hypochlorite. The aqueous solution provides a mouth rinse for oral hygiene or a sterilizing solution for surgical or dental tools or for treating drinking water. The generator comprises a chamber, an anode and a cathode disposed for fluid communication with a reservoir, and an electrical power source for applying a voltage between the anode and the cathode. The reservoir contains an electrolyte having a metal chlorite and, optionally, a metal chloride, citric acid, sweeteners, flavorings and combinations thereof. The anode is preferably a dimensionally stable anode coated with RuO2, IrO2 or combinations thereof. The cathode may be made of titanium substrate coated with platinum. The apparatus and method generate an aqueous solution containing chlorine dioxide that may be used immediately for oral hygiene.
