Definitions

• the invention relates to detergents and cleaning agents which contain a combination of one or more color fixing agent (s) and one or more soil release polymer (s).
• a known problem with washing colored textiles is that they fade over several washing cycles. This problem occurs particularly with dark-colored textiles made of cotton and cotton blended fabrics. In the case of well-fixed textile dyes, this process takes place over a longer period of use. If, on the other hand, the dyes of a dyed textile are poorly fixed, that is to say the textile "bleeds", not only does the colored textile fade quickly, but it can also, due to the relatively high dyestuff concentrations in the wash liquor, also stain other colors or those washed with it white textiles come in. In any case, colored textiles lose their new appearance relatively quickly, which limits the useful life of the textile.

• Disinfectants alkalis, hydrotropic compounds, antioxidants, perfumes, solvents, solubilizers, redeposition inhibitors, dispersants, processing aids, plasticizers and antistatic agents.
• the detergent compositions of the present invention may optionally contain one or more conventional bleaches, as well as bleach activators, bleach catalysts and suitable stabilizers. In general, it must be ensured that the bleaching agents used are compatible with the detergent ingredients. Conventional test methods, such as the determination of the bleaching activity of the formulated cleaning agent depending on the storage time, can be used for this purpose.
• Peroxyacids can either be used as free peroxyacids, or a combination of an inorganic persalt, e.g. sodium perborate or sodium percarbonate, and an organic peroxyacid precursor can be used.
• organic peroxyacid precursors are often referred to in the art as bleach activators.
• compositions suitable for bleaching laundry and containing perborate bleaches and activators are described in U.S. 4,412,934, U.S. 4,536,314, U.S. 4,681, 695 and U.S. 4,539,130.
• peroxyacids preferred for use in this invention include peroxydodecanedioic acid (DPDA), nonylamide of peroxysuccinic acid (NAPSA), nonylamide of peroxyadipic acid (NAPAA) and decyldiperoxysuccinic acid (DDPSA), nonanoyl-amidocaproyloxonic acid and oxy-benzoic acid Alkanoyloxybenzenesulfonic acids such as nonanoyloxybenzenesulfonic acid (NOBS) and lauroyloxybenzenesulfonic acid (LOBS).
• DPDA peroxydodecanedioic acid
• NAPSA nonylamide of peroxysuccinic acid
• NAPAA nonylamide of peroxyadipic acid
• DDPSA decyldiperoxysuccinic acid
• NOBS nonanoyloxybenzenesulfonic acid
• LOBS lauroyloxybenzenesul
• Bleaching systems based on a persalt such as perborates or percarbonates with the bleach activator tetraacetylethylene diamine (TAED) are particularly preferably used in the detergents and laundry treatment agents according to the invention.
• liquid detergent formulations A, B and C were prepared (see Table 1).
• Formulation A serves as a reference.
• Formulation B additionally contains a color fixative and formulation C contains the combination according to the invention of a color fixative with a soil release polymer.
• the dirt reduction position was examined on cotton fabric wfk 10 A, cotton / polyester blend fabric wfk 20 A and polyester fabric wfk 30 A in a Miele household washing machine.
• TexCare DFC 6 polyamine derivative. Color fixative for detergents / Fa. Clariant TexCare SRN-170: Nonionic Soil Release Polyester / Fa. Clariant
• test fabric with the detergent formulations was subjected to multiple washings with the addition of standardized test dirt wfk pigment dirt 09V (see Table 2).
• Table 2 Washing conditions
• the whiteness of the test fabrics at the beginning, after five, 10 and 15 washing cycles was determined as a measure of the dirt reduction position. The higher the whiteness, the lower the dirt reduction position.
• Table 3 Whiteness of cotton wfk 10 A after multiple washing
• Table 4 Whiteness of cotton / polyester wfk 20 A after multiple washing
