- the use of silicates or carbonates as buffers in chlorine bleaching liquors can be found, for example, in documents US 4,623,476 (Procter & Gamble) and EP-A1 0079102 and EP-A1 0137551 (Unilever).
- the complex object of the invention has been the yellowing of the laundry counteract by the influence of heavy metal ions and available sequestrants places that allow the production of aqueous bleaching agents, especially chlorine bleach, which are also chlorine stable. are gentle on textiles and are as compatible with the skin as possible have high viscosity and with high stain removal capacity, the deposition of Prevent metal traces on the fabric reliably.
- the invention includes the knowledge that the use of mild, chlorine-stable Surfactants such as preferably alkyl ether sulfates, amine oxides, alkyl and / or alkenyl oligoglycosides and Fatty acid salts to further improve the stabilization against yellowing, the cleaning performance and dermatological tolerance.

- lignin sulfonates are the alkali, alkaline earth, ammonium.
- Aluminum or zinc salts To understand ligninsulfonic acid, for example, in the sulfite digestion of wood as a reaction product of natural lignin and sulphurous acid. Those that come into consideration in the sense of the invention Lignin sulfonates can average molecular weights of 500 to 200,000, preferably 10,000 to 50,000 daltons, the number of sulfonic acid groups can be based on one Phenylpropane unit are in the range of 1 to 5.
- the aqueous bleaching agents can contain hydrogen peroxide, but they are preferably chlorine bleach containing alkali hypochlorite.
- Alkali hypochlorites include lithium, To understand potassium and especially sodium hypochlorite.
- the hypochlorites can be found in amounts of 1.5 to 10, preferably 2 to 8 and in particular 4 to 6% by weight, based on the composition, are used become.

- the average molecular weight of the polyacrylates can vary over a wide range scatter and is between 300 and 5,000,000, preferably 1,000 to 1,000,000, in particular 50,000 to 500,000 and particularly preferably 100,000 to 250,000 Daltons.
- phosphonates are used as electrolyte salts. These include both inorganic phosphonates (also known as secondary phosphites) of the formula (I), HP (O) (OM 1 ) 2 (I) in which M represents an alkali or alkaline earth metal, aluminum or zinc, preferably sodium, and also organic phosphonates of the formula (II), R 1 P (O) (OR 2 ) 2 (II)
- R 1 and R 2 independently of one another represent hydrogen or linear or branched, optionally functionalized hydrocarbon radicals having 1 to 22, preferably 4 to 12 carbon atoms, with the proviso that R 1 and R 2 cannot simultaneously be hydrogen.
- organic phosphonates are methylphosphonate, ethylphosphonate, butylphosphonate, 2-ethylhexylphosphonate and amino-functionalized phosphonates such as, for example, aminomethylenephosphonate or aminoethylenephosphonate.
- a further group of suitable phosphonates are species which are linked to one another via functional groups, such as, for example, nitrilotris (methylene phosphonate) or nitrilotris (ethylene phosphonate).
- amine oxide phosphonic acids such as those offered by Bozetto / IT under the name Sequion®.
- the electrolyte salts support the sequestering effect of the lignin sulfonates and ensure that the Preparations have a constantly high alkaline pH in the range from 10 to 14 Lignin sulfonates and the electrolyte salts can be in a weight ratio of 95: 5 to 5:95, preferably 80 : 20 to 20: 80 and in particular 60: 40 to 40: 60.
- the amount of the Electrolyte mixtures containing lignin sulfonates and electrolyte salts can be 0.01 to 5, preferably 0.1 up to 2 and in particular 0.5 to 1% by weight, based on the composition.
- the bleaches obtainable using the electrolyte mixtures according to the invention have usually a non-aqueous content of 5 to 35 and preferably 8 to 15 wt .-% on and are preferably suitable for the treatment of textile fabrics, such as yarns, Fabric and especially textiles. They are usually used at low levels Temperatures, i.e. in the cold wash area (approx. 15 to 25 ° C). The funds are not just outstanding excellent stain removal, but reliably prevent the deposition of Traces of metal on the fibers and thus also prevent yellowing. Although the real one Use of the agent aimed at removing stains during washing, they are suitable basically also for other purposes in which hypochlorite solutions are used, for example for cleaning and disinfecting hard surfaces
- auxiliaries and additives which may be used are, for example, other chlorine-stable surfactants or hydrotropes, such as alkyl sulfates and alkyl sulfonates.

- soiled tissue was treated with various chlorine bleaches.
- the yellowing of the tissue was determined photometrically, the initial value of the soiled tissue serving as the standard (100%).
- the measurements were carried out in a liquor with a metal ion content of 300 ppb Fe and 100 ppb Mn; the water hardness was 1000 ppm CaCl 2 , the hydrogen carbonate content was 0.013% by weight.
