Definitions
- Agents of the latest phosphate-free generation for the automatic cleaning of dishes contain, in addition to surface-active substances, oxygen-based oxidizing agents and a relatively complex builder combination of alkali carbonates and organic complexing agents.
- the organic complexing agents used to date include organophosphonic acids, hydroxycarboxylic acids, aminocarboxylic acids and in particular polymeric polycarboxylic acids, which are often used in admixture with low molecular weight polyhydroxypolycarboxylic acids, for example citric acid, or their water-soluble salts.
- alkali silicate is usually present as a further builder component.
- composite detergents for machine dishwashing in tablet form and a manufacturing process for such tablets are proposed.
- the method comprises the separate production of a cleaning additive containing polymeric polycarboxylate, sodium carbonate, sodium sulfate and water, which is pressed together with other components, in particular sodium silicate.
- Detergents composed as described above frequently have the disadvantage, particularly when the water hardness is relatively high, that limescale deposits form, both in the dishwasher used and in particular on the cleaned items.
- International patent application WO-A-92/01035 relates to a method for producing agents with a high bulk density for cleaning dishes by agglomerating silicate-free builder material, for example phosphate, carbonate or polycarboxylate, with a binder and admixing alkali silicate and bleach.
- 3,629,121 describes solid phosphate and chlorine free agents which contain nonionic surfactant and oxidation products of polysaccharides, e.g. Dicarboxyl starch containing aldehyde groups.
- the agents disclosed there lack oxygen-based oxidizing agents.

- oxidizing agents are used for the oxidation of polyglucosans. Examples include (air) oxygen, hydrogen peroxide, sodium hypochlorite or bromite, periodic acid or periodates, lead (IV) acetate, nitrogen dioxide and cerium (IV) salts. These oxidants react very differently with the anhydroglucose units, cf. for example the formula pictures in Houben-Weyl loc. cit. p. 2124. It is known that when nitrogen dioxide acts on cellulose, the oxidation of the primary alcohol group to the carboxy group is the predominant reaction.
- the oxidizing agent can be used in gaseous form or dissolved in an inert organic solvent, cf.
- monocarboxyl starches with a freely selectable degree of conversion of the primary alcohol groups can also be produced without additives, for example solvents or catalysts, by their selective oxidation with nitrogen dioxide at low temperatures.

Quantities in the range from 15% by weight to 30% by weight can often be expedient.
