TECHNOLOGY FOCUS - ELECTRONICS - Preferred Process: The non-thermal electrical discharge process is a glow discharge plasma or a corona discharge, preferably a pulsed DC glow discharge plasma, more preferably a pulsed corona induced pulsed DC glow discharge plasma. The glow discharge plasma or the corona discharge is operated in a pulsed mode and/or is a direct current (DC) discharge (plasma). Preferred Components: The glow discharge plasma is a pulsed corona induced pulsed DC glow discharge plasma, preferably performed at a frequency of 50-5000 Hz, more preferably 100-1000 Hz.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: (I): has a hydrogen peroxide content of 0.1-15%, preferably 0.4-3%; has a pH of 2.5-4, preferably 2.5-3.5; and has an ORP of 400-500, preferably 420-490 mV. The water is potable, tap, demineralized, chemically pure and/or distilled water. The additive is silver salts; colloidal silver; zinc salts; chlorhexidine; anionic, cationic, non-ionic and/or amphoteric surfactants; emulsifiers; hydrotropes; glycerol; stannates; chelating agents; alcohols; acids; bases; fragrances; coloring chemicals; and/or surface tension decreasing agents. Preferred Process: (I) is obtainable by subjecting a solution of hydrogen peroxide (0.05-20% (w/w)) in water to a non-thermal electrical discharge process. ADMINISTRATION - (I) is applied by a spray device, aerosol can, aerosol generation device for room disinfection and the application is in the form of dipping (claimed).    EXAMPLE - To chemically pure distilled water (600 ml) having a pH of 6.7 and an electrical conductivity of less than 0.1 muS/cm, concentrated hydrogen peroxide was added to reach a 1.6% hydrogen peroxide content, and the solution was subjected to a pulsed corona induced pulsed DC glow discharge plasma process. The pH of the solution before activation was 5.8. The solution was put in a 1 l double walled water cooled vessel. One electrode was submersed in the aqueous solution and three pin shaped electrodes were placed 10 mm above the liquid surface. Pressure was lowered and the reactor chamber cooled with cooling water. The water was then processed by pulsed corona induced low frequency pulsed DC plasma discharge, the pulsed corona induction voltage was 10 kV, the pulsed DC plasma voltage was 1500-1700 Volt, the frequency was 100 Hz, and the pressure in the reaction chamber was 1.5x104 Pa. The resulting ORP of the solution was 494 mV, the pH of the solution was 2.92, and the gross concentration of hydrogen peroxide and super-peroxide compounds was 1.6%.
