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

1-10. -10. (canceled)

11. A composition comprising a first oxidant comprising a water-soluble permanganate, an alkaline agent, and a second oxidant whose oxidation potential exceeds that of a mixture containing 50 mol % manganese VII and 50 mol % manganese VI;

said composition changes color upon contact with a substance external to said composition, wherein the alkaline agent in said composition has a concentration such that the alkaline agent produces a pH of at least 12 in a resulting aqueous solution ready for use as a cleaning agent.

12. A composition as claimed in claim 11, wherein the aqueous solution is made from a powder product dissolved in water.

13. A composition as claimed in claim 11, wherein the second oxidant comprises a peroxodisulfate.

14. A composition as claimed in claim 11, wherein the aqueous solution is made from a liquid concentrate product diluted with water.

15. A composition as claimed in claim 14, wherein the second oxidant comprises a hypochlorite.

16. A composition as claimed in claim 14, wherein the second oxidant comprises a peroxodisulfate.

17. A composition as claimed in claim 12, wherein the decomposition of peroxodisulfate is accelerated by means of one-electron-transfers.

18. A composition as claimed in claim 11, comprising polyphosphates that exhibit a protective effect against the corrosion of non-ferrous metals and plastics.

19. A composition as claimed in claim 12, wherein a formation of oxygen and hydrogen peroxide will occur upon oxidation of organic substances.

20. A composition as claimed in claim 11, wherein the germicidal speed of the substances present in the composition is increased by the formation of OH radicals, oxygen and hydrogen peroxide.
