Definitions
- the present invention relates to the use of particular organic compound
- Mediatorharmen to enhance the cleaning performance of detergents and cleaning agents against stains, washing or cleaning processes using such mediator compounds generated bleach-active species and washing and cleaning
- Peroxygen compounds that dissolve in water releasing 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 oxidative effect of the inorganic peroxygen compounds can be improved by the addition of so-called bleach activators, which are capable of being among those mentioned
- transition metal compounds in particular transition metal complexes, to increase the oxidation power of peroxygen compounds or atmospheric oxygen in washing and
- Transition metal compounds include, for example, manganese, iron, cobalt, ruthenium or molybdenum-salene complexes, manganese, iron, cobalt, ruthenium or molybdenum carbonyl complexes, manganese, iron, cobalt, ruthenium, molybdenum, Titanium, vanadium and copper complexes with nitrogen-containing tripod ligands, and manganese complexes with
- Polyazacycloalkane ligands such as TACN.
- TACN Polyazacycloalkane ligands
- 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.
- bleachable stains can also be bleached using bleach-free detergents, for example in liquid form, if the detergent contains a so-called mediator which is activated by means of an electrochemical cell arranged inside or outside the washing machine, the wash liquor furthermore contains water-insoluble solid particles.
- the mediator is an electrochemically activatable bleach precursor.
- the activated species generated electrochemically from the mediator acts as an oxidizing bleach and therefore can oxidatively discolor colored ingredients contained in the wash liquor. If the electrochemically produced bleaching-active species is stable in the wash liquor for a sufficiently long time, it can pass with the liquor to the dirt present on the textile and unfold the bleaching performance there.
- the power of the arranged inside or outside the machine electrochemical cell can be controlled individually on the current and duty cycle.
- the bleaching performance can be adjusted to the degree of soiling and the nature of the treated textiles. If the electrochemical cell is inactive, the mediator will show no bleaching performance. in the Detergent product is the mediator thus contained in an inactive form, so that it can not damage sensitive components of the detergent, such as enzymes, dyes and fragrances.
- the present invention is therefore in a first embodiment, an aqueous wash liquor in a device for the purification of textile substrates containing a plurality of water-insoluble solid particles and a MediatorENS which is suitable in an electrochemical cell under electrical voltage in the wash liquor an oxidizing
- Bleach produce It is also possible to use mixtures of two or more mediators.
- the invention relates to the use of mediator compounds, which by means of
- electrochemical reaction to bleach-active species can be activated and to reinforce the cleaning performance of detergents and cleaners, here in conjunction with a washing process in which the wash liquor contains water-insoluble solid particles, can be used against stains, especially bleachable stains, in a preferred liquid detergent.
- the intended detergent can be used in a particularly advantageous manner together with the washing process, since by the small amount of water easily high concentrations of active mediator can be achieved.
- the present invention therefore also relates to a corresponding process for washing soiled textile substrates using the above-mentioned wash liquor and a washing machine (apparatus for cleaning soiled textile substrates) having at least one laundry treatment space for receiving the substrates, comprising a plurality of water-insoluble solid particles a reservoir for receiving the particles inside or outside the device and an electrochemical cell consisting of a cathode and an anode and a power supply, wherein the area around the anode is in fluid communication with the wash liquor in the laundry treatment room.
- the electrodes contain stainless steel and / or graphite, in particular consist thereof. It is very particularly preferred according to the invention if the cathode is made of stainless steel and the anode is made of graphite. However, the cathode and anode are preferably not necessarily located in separate spaces, which may be separated from one another by a diaphragm or a membrane, the anode space preferably being in fluid communication with the laundry treatment space of the washing machine.
- the present invention is particularly suitable for use with or in liquid, generally bleach-free, detergent.
- mediators provides a solution to the problem of low bleaching performance associated therewith and, if the agent contains bleach, poor stability of other ingredients because the bleaching species in the product is inactive and activated only by electrochemical reaction.
- the present invention further comprises the use of mediators whose active state is particularly short-lived. It can thereby be achieved that the mediator is active only in the immediate vicinity of the anode of the electrochemical cell and bleaches in this way only in the wash liquor dispersed or dissolved dye.
- Electrochemical cell is advantageously arranged in a bypass in this method. If the wash liquor from the electrochemical cell back into the laundry room of the washing machine, the mediator should have already reacted, so that it can cause any color and fiber damage to the textiles located there. In this way, it is possible to rid the wash liquor of detached dyes even with ausfärbenden dyes, so that a common washing of different colored textiles is possible.
- Dyes from the textile substrate are the following features of importance:
- the lifetime of active species formed from the mediator should be as short as possible (less than 1 minute) to reduce the risk of discoloration or discoloration of colored fabrics;
- the mediators should have a high electro-activation rate (activation of non-active to active state using the electrochemical method);
- the mediators should have high effectiveness for a wide range of dyes (not selective for a particular number of dyes) or should include a mixture of free radicals / mediators to attack different dyes.
- the mediators should continue to have a high rate of reactivation (the vast majority of applied mediator molecules should be suitable to be reactivated at the anode).
- the present invention further comprises the use of mediators whose active state is particularly durable. It can thereby be achieved that the activated species arising from the mediator is also active away from the anode of the electrochemical cell and, when it encounters a spot located on the textile, unfolds its bleaching effect there.
- the essential properties of the mediator for use in the removal of bleachable stains present on the textile substrate are as follows:
- the active species formed from the mediator should be stable for at least 1 minute to move from the anode (site of electroactivation) to the soiled textile substrate in the
- Mediator molecules should be suitable to be reactivated at the anode
- the mediator should be suitable for a wide range of bleachable soils. Alternatively, a mixture of mediators may be used to treat different stains.
- the preferred voltage for the electrochemical cell is 0.2 to 5 volts, especially 1 to 3 volts.
- the life of the activated species should preferably be 0.1 to 120 minutes and be for bleaching applications on textiles, in particular in the range of 3 to 60 minutes and for the decolorization of dyes in the wash liquor in particular ⁇ 10 seconds.
- the concentration of the mediator in the liquid fraction of the wash liquor is preferably 0.05 to 10 mmol / l, more preferably 0.1 to 2 mmol / l.
- the liquid portion of the wash liquor is understood as the proportion of the total wash liquor including the water-insoluble solid particles obtained by centrifuging 8 kg of the wash liquor containing the solid water-insoluble particles for 5 minutes in a centrifuge with the water-insoluble solid particles separated cylindrical rotating body of 515 mm inner diameter and 370 mm internal depth at 1400 revolutions per minute from the liquid portion.
- the pH values of the wash liquor can be varied within a wide range. Particular preference is given to pH values in the range from 2 to 12, in particular 4 to 11.
- the method and apparatus defined above uses less water (in terms of weight of fabric) compared to a conventional wash. As a result, even small amounts of mediator can give effective concentration and achieve good bleaching effect.
- the active species electrochemically generated from the mediator contained in the detergent prevents germ growth on the water-insoluble particles.
- the duration of use of the particles can be increased, which has a positive effect on the carbon footprint of the process.
- the activity of the cleaning system can be controlled in a simple manner by adjusting the current in the electrochemical cell depending on the tissue and degree of contamination.
- the activity of the bleach system can be activated at any time during the wash cycle (eg, only at the end). This can be beneficial to the performance of others
- Detergent ingredients such as enzymes, as they may initially work in a bleach-free environment.
- Useful mediator compounds are organic compounds which can be electrochemically oxidized or reduced in an aqueous system, preferably in aqueous solution.

- the anionic substituent in the 2,2,6,6-tetramethylpiperidine derivatives is preferably selected from the SCb ' group, the CCte ' group, the P03 2 ⁇ group and mixtures thereof.
- the anionic substituent may be attached directly or preferably via a spacer to a carbon atom of the piperidinyl ring.
- a spacer is preferably selected from alkylene groups, aminoalkylene groups, oxyalkylene groups, aminocarbonylalkylene groups, oxycarbonylalkylene groups each having 1 to 25 C atoms, and mixtures thereof.
- a molecule may also carry a plurality of anionic substituents; if desired, these may be located on a spacer or on a plurality of spacers.
- anionically substituted 2,2,6,6-tetramethylpiperidine derivative countercations are as

- 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 free-radical or N-oxoammonium species produced in this way impinges on dyes contained in the wash liquor or reaches the dirt present on the textile with the aqueous wash liquor, removing an electron from the dye or the soiling and thereby a less colored and / or more water soluble and / or dispersible material is formed.
- the mediator compound is reformed from the bleaching-active species by this reaction, resulting in a reversible redox system. It is possible to electrochemically react 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 and intensity of the electrochemical treatment the degree of contamination of the laundry can be adjusted.
- the production of the bleaching-active species is also possible in that the mediator compound, especially when using a conventional dispensing device, passes through an electrochemical cell before entering the chamber of a washing machine, in particular in an aqueous solution or slurry flows through an electrochemical cell Supply line be installed inside or outside the machine.

- An essential feature of the device according to the invention is the presence of the electrochemical cell, which is preferably integrated in the device, the above-mentioned water-insoluble solid particles and a reservoir for the particles.
- the apparatus of the invention typically includes a trap door in a housing to allow access to the interior of the washing tub to provide a substantially closed system.
- the door includes a window of the stationary cylindrical drum rotatably supported in another drum while the rotatably supported cylinder drum is mounted vertically inside the housing. Consequently, a
- the stationary cylindrical drum may be mounted vertically within the housing and the access device located in the top of the device.
- the device is suitable for providing contact of the particles with the soiled substrate. Ideally, these particles should be efficiently circulated to promote effective purification.
- the device comprises at least one reservoir, in particular with a corresponding control, for the water-insoluble solid particles, for example located inside the washing machine and suitable for controlling the flow of particles within the washing machine and containing the particles for regeneration.
- the measures of the process according to the invention make it possible to regenerate the water-insoluble solid particles, and the particles can be satisfactorily reused in the purification process, although some deterioration in performance generally occurs after three uses of the particles is watching.
- the regeneration of the water-insoluble solid particles can be carried out in a manner known per se, as described, for example, in WO 2012/035342 A1.
- the regeneration is carried out by introducing the particles optionally with industrial chemicals and / or the detergent into the device having the electrochemical cell, for example in a separate rinse, optionally by adding further cleaning agents, which may also be aggressive in nature.
- the temperature of the regeneration step is independent of the washing temperature when the textile substrate has been removed from the washing machine before regeneration.
- the usual detergent raw materials can be used.
