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 comprising:

water-soluble permanganate, which is provided for initiating the oxidation of organic substances, an agent for securing an alkaline environment with a pH value of at least 10, and at least one further oxidant whose oxidation potential lies over that of manganese VII to manganese VI.

2. A detergent and disinfectant as claimed in claim 1, wherein said further oxidant comprises peroxidisulfate.

3. A detergent and disinfectant as claimed in claim 1, wherein said water soluble permanganate is potassium permanganate.

4. A detergent and disinfectant as claimed in claim 1, further comprising alkali hydroxides which are used for achieving the alkaline environment.

5. A detergent and disinfectant as claimed in claim 1, further comprising hardness stabilizers, wherein oxidation-resistant polyphosphates are used as hardness stabilizers.

6. A detergent and disinfectant as claimed in claim 1, wherein all components are present in powder form.

7. A detergent and disinfectant as claimed in claim 1, wherein 7 to 8 grams of the detergent and disinfectant are dissolved per liter of solution of detergent or disinfectant.
