Electrolyzed water composition

A method for producing an electrolyzed water composition that is devoid of free accessible chlorine (FAC), the method comprising:

• preparing a starting electrolyte solution comprising water, at least one carbonate salt selected from:
• anhydrous alkali metal carbonate salts, and at least one chloride salt selected from:
• alkali metal chloride salts and/or alkali earth metal chloride salts, in which the total salt concentration of carbonate salts and chloride salts in the electrolyte solution is in the range of between 5 g/l and 50 g/l, and in which the ratio of the carbonate salts to chloride salts by weight within the electrolyte solution is in the range of between 0.5:1 to about 2.0:1;
• introducing the starting electrolyte solution into the chamber of an electrolytic cell comprising a plurality of boron-doped diamond electrodes and metal contact plates;
• operating a power supply to apply a predetermined voltage to the starting electrolyte solution within the electrolytic cell;
• and
• producing an electrolyzed water composition that is FAC-free and comprises a plurality of active molecular and ionic species selected from the group consisting of ozone, hydrogen peroxide, hydroxyl ions and hydronium ions.
