Abstract:
The present invention discloses a composition for use in a foam dispenser comprising: 0.1-5% (w/w) hydrogen peroxide, 21-55% (w/w) of a C2-C6 alcohol, and 0.01-2% (w/w) of a foam booster. The foam booster is capable of providing a stable foam when dispensing a composition consisting of 36% (w/w) ethanol and 0.2% (w/w) of the foam booster from a foam dispenser. The composition provided as a foam is suitable for disinfecting skin and/or mucous membranes.
Abstract:
The present invention discloses an activated biocidal aqueous solution containing hydrogen peroxide (activated peroxide solution) obtainable by subjecting an initial solution of hydrogen peroxide in water to a non-thermal electrical discharge process, such as a glow discharge plasma or a corona discharge. The resulting activated peroxide solution has a pH in the range of 2 to 4, a electrical conductivity of 100-400 microSiemens/cm, and an oxidation-reduction potential (ORP) in the range of 300 to 600 mV as measurable under conditions essentially without the presence of additional compounds in the solution. The biocidal activity of the solution is substantially higher than that of a common peroxide solution. The biocidal solution may be used for any purpose where disinfecting and/or sanitizing and/or cleaning and/or bleaching and/or preservative activity is required. The present invention further discloses a non-thermal electrical discharge process, in particular a pulsed corona induced low frequency pulsed DC plasma discharge process, for the preparation of the activated peroxide solution.
