Definitions
- the present invention relates to the use of certain organic mediator compounds for enhancing the cleaning performance of detergents and cleaners against stains, washing or cleaning processes using bleach-active species produced from such mediator compounds and detergents and cleaners containing the mediator compound.
- Inorganic peroxygen compounds particularly hydrogen peroxide and solid peroxygen compounds which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfecting and bleaching purposes.
- the oxidation effect of these substances in dilute solutions depends strongly on the temperature; Thus, for example, with H2O2 or perborate in alkaline bleaching liquors only at temperatures above about 80 ° C, a sufficiently fast bleaching of soiled textiles.
- the oxidation effect of the inorganic peroxygen compounds can be improved by adding so-called bleach activators which are able to provide peroxycarboxylic acids under the abovementioned perhydrolysis conditions and for the numerous proposals, especially from the classes of N- or O-acyl compounds, for example reactive esters, polyacylated alkylenediamines, in particular ⁇ , ⁇ , ⁇ ', ⁇ ' -Tetraacetylethylendiamin (TAED), acylated glycolurils, in particular Tet raacetylglykoluril, N-acylated hydantoins, hydrazides, triazoles, Hydrotriazine, urazoles, piperazine diketo-, sulfuryl amides and cyanurates also carboxylic anhydrides, in particular phthalic anhydride, carboxylic acid esters, in particular sodium nonanoyloxy-benzenesulfonate (NOBS), sodium
- transition metal compounds in particular transition metal complexes, for increasing the oxidation force of peroxygen compounds or also atmospheric oxygen in detergents and cleaners have been proposed.
- the transition metal compounds proposed for this purpose include, for example, manganese, iron, cobalt, ruthenium or molybdenum salt complexes, manganese, iron, cobalt, ruthenium or molybdenum carbonyl complexes, manganese, iron and cobalt , Ruthenium, molybdenum, titanium, vanadium and copper complexes with nitrogen-containing tripod ligands, and manganese complexes with polyazacydoalkane ligands such as TACN.
- a disadvantage of such metal complexes is that they either do not have sufficient bleaching performance, in particular at low temperature, or, if the bleaching performance is adequate, undesirably damage the colors of the material to be washed or cleaned and possibly even of the material itself, for example the textile fibers, can come.
- bleach-active species can be produced from sterically hindered N-hydroxy compounds such as, for example, 1-hydroxy-2,2,6,6-tetramethylpiperidine by means of electrolysis, which have a bleaching-enhancing effect.
- An object of the invention is accordingly the use of electrolytically by a redox reaction of anionically substituted 1-hydroxy-2,2,6,6-tetramethylpiperidine, 2,2,6,6-tetramethylpiperidine-N-oxide or (2 , 2,6,6-Tetramethylpiperidin-1-yl) oxy generated bleaching-active species to enhance the cleaning performance of detergents and cleaners, especially against bleachable and / or protein-containing stains, in aqueous, especially surfactant-containing liquor.

These are accessible from 4-hydroxy or 4-amino-2,2,6,6-tetramethylpiperidine N-oxide or the corresponding hydroxylamine compounds or the corresponding oxyl radicals.
- the preparation of the bleaching-active species can be carried out in a simple manner by adding an aqueous system containing the mediator compound to an electrical potential difference applied between at least two electrodes, which is preferably 0.2 V to 5 V, in particular 1 V to 3 V, submits so that the mediator compound gives off an electron.
- an electrical potential difference applied between at least two electrodes which is preferably 0.2 V to 5 V, in particular 1 V to 3 V.
- a radical or N-oxoammonium species produced in this way reaches the dirt with the aqueous liquor, removes an electron from the soiling and thus turns the soiling into a less colored and / or better water-soluble and / or or dispersible material is formed.
- the mediator compound is reformed from the bleaching-active species by reaction with the soil so that a reversible redox system is present. It is possible to electrolyze the liquor containing the mediator compound continuously or once or several times for certain periods, for example 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes or 60 minutes, the duration of the electrolysis being adapted to the degree of soiling of the laundry can be.
- the production of the bleaching-active species is also possible in that the mediator compound, in particular when using a conventional dispensing device, passes an electrolysis device before it enters the chamber of a washing machine or dishwashing machine, in particular in an aqueous solution or slurry an electrolytic cell flows through it the supply line can be mounted inside or outside the machine. Alternatively, it is possible at the beginning of the process, other active ingredients, such as enzymes, unaffected perform their performance, and only later by switching on the electrolysis device to start the bleaching effect.
