Definitions
- the present invention relates to the use of certain transition metal complex compounds for enhancing the bleaching action of, in particular, inorganic peroxygen compounds when bleaching colored stains both on textiles and on hard surfaces, and on detergents and cleaning agents which contain such complex compounds.
- Inorganic peroxygen compounds in particular hydrogen peroxide and solid peroxygen compounds which dissolve in water with the liberation of hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfection and bleaching purposes.
- the oxidizing effect of these substances in dilute solutions depends strongly on the temperature; For example, with H 2 O 2 or perborate in alkaline bleaching liquors, sufficiently quick bleaching of soiled textiles can only be achieved at temperatures above about 80 ° C.
- the oxidation effect of the inorganic peroxygen compounds can be improved by adding so-called bleach activators, for which numerous suggestions, especially from the classes of the N- or O-acyl compounds, for example multiply acylated alkylenediamines, in particular tetraacetylethylenediamine, acylated glycolurils, in particular tetraacetylglycoluril, N-acylated hydantoins, hydrazides, triazoles, hydrotriazines, urazoles, diketopiperazines, sulfurylamides and cyanurates, and also carboxylic acid anhydrides, especially phthalic anhydride, carboxylic acid esters, especially sodium nonanoyloxy-benzenesulfonate, sodium isononanoyloxy-benzenesulfonate, and known became.

- the bleaching effect of aqueous peroxide liquors can be increased to such an extent that even at temperatures around 60 ° C essentially the same effects occur as with the peroxide liquor alone at 95 ° C.
- application temperatures significantly below 60 ° C, in particular below 45 ° C, down to the cold water temperature have become increasingly important in recent years.
- transition metal complex compounds with certain dendrimer ligands make a significant contribution to cleaning performance against colored stains which are found on textiles or on hard surfaces. This contribution can be further increased if the complexes are used in combination with compounds which split off peroxocarboxylic acid under perhydrolysis conditions.
