Abstract

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.

Claims

1. A detergent and disinfectant containing water-soluble permanganate, characterized in that in addition to the water-soluble permanganate which is provided for initiating the oxidation of organic substances the agent additionally comprises an agent for securing an alkaline environment with a pH value of at least 10, preferably at least 12, and is used in combination with at least one further oxidant whose oxidation potential lies over that of manganese VII to manganese VI, preferably over that of HO₂⁻

to OH⁻

.

2. A detergent or disinfectant as claimed in claim 1, characterized in that peroxodisulfates, preferably sodium peroxodisulfate, are used as a further oxidant.

3. A detergent or disinfectant as claimed in claim 1 and 2, characterized in that potassium permanganate is used as permanganate.

4. A detergent or disinfectant as claimed in claim 1 to 3, characterized in that alkali hydroxides, preferably NaOH, are used for achieving the alkaline environment.

5. A detergent or disinfectant as claimed in claim 1 to 4, characterized in that oxidation-resistant polyphosphates are used as hardness stabilizers, preferably potassium tripolyphosphate.

6. A detergent or disinfectant as claimed in one of the claims 1 to 5, characterized in that it is used in the following composition:

50%-70% NaOH, preferably 58%

20%-35% potassium tripolyphosphate, preferably 27%

10%-20% Na₂S₂O₈, preferably 15% at least 0.01% KMnO₄

7. A detergent or disinfectant as claimed in one of the claims 1 to 6, characterized in that all components are present in powder form.

8. A detergent or disinfectant as claimed in one of the claims 1 to 7, characterized in that 7 to 8 grams of the detergent and disinfectant are dissolved per liter of solution of detergent or disinfectant.

9. A detergent or disinfectant as claimed in one of the claims 1 to 5, characterized in that it is used in the following composition:

20%-35% of 50% KOH, preferably 28%

5%-25% of 50% potassium tripolyphosphate, preferably 15%

25%-35% of hypochlorite lye, preferably 30% at least 0.01% KMnO₄

10. A detergent or disinfectant as claimed in claim 9, characterized in that it is used in a 3% hydrous solution.
