A detergent and disinfectant in which water-soluble permanganates are used in an alkaline solution in order to initiate the oxidation of organic substances and simultaneously a chemical oxidant, preferably a peroxodisulfate, is used which is capable of producing radical reactions with catalytic support by manganates originating from the supplied permanganate, which reactions produce the oxidation of organic substances. All components are present in powder form and a respective powder mixture can be dissolved rapidly and free from residues in water. It thus represents a universally applicable, highly effective detergent and disinfectant.

Why it's free to use
- Filed July 26, 2001 and granted February 14, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 26, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 26, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
