Under detergent formulations all cleaners for hard surfaces should be understood, e.g. Dishwashing detergent, industrial bottle washer cleaner, Cleaner for dairies and floor cleaning agents.
- the reaction products are preferably in textile detergents used. They have good dispersibility in the detergent fleet for particle dirt, especially for clay minerals (Clay). This property is important because it is clay-like Soiling of textile goods is widespread.
- the implementation products also act as a builder for detergents and cause a reduction in the incrustation during the washing process and the graying on the washed textile. they are thus also suitable as incrustation and graying inhibitors.
- composition of the washing and cleaning formulations can be very different.
- Detergents and cleaning agents included usually 2 to 50 wt .-% surfactants and optionally builders. This information applies to both liquid and powdery Detergents and cleaning agents. Examples of the composition of detergent formulations used in Europe, the United States and are common in Japan can be found, for example, in Chemical and Engn. News, Vol. 67, 35 (1989) tabulated. Further information on the composition of detergents and cleaning agents can WO-A-90/13581 and Ullmanns Encyklopadie Technical Chemistry, Verlag Chemie, Weinhein 1983, 4th edition, Pages 63-160 are taken.
- Such detergent formulations are also of interest, up to 60 wt .-% of an alkali silicate and up to 10% by weight of a polycondensate according to the invention contain.

- the detergents and cleaning agents can, if necessary contain other common additives, e.g. Complexing agents, citrates, Opacifiers, optical brighteners, enzymes, perfume oils, color transfer inhibitors, Graying inhibitors and / or bleach activators.
- reaction products are also used as water treatment agents suitable. They are usually in amounts from 1 to 1000 ppm of water in cooling circuits, evaporators or sea water desalination plants added. They also act as a deposit inhibitor in the evaporation of sugar juice. They will Thin sugar added in amounts of 0.1 to 1000 ppm.

- a standing cylinder 100 ml
- Immediately after stirring, take from the center of the standing cylinder a 2.5 ml sample and determined after dilution to 25 ml the turbidity of the dispersion with a turbidimeter. After 30 or Samples are taken again for 60 minutes of the dispersion and how the turbidity determines above.
- the turbidity of the dispersion is specified in NTU (nephelometric turbidity units).
- TAV test The clay detachability (TAV test) of textile fabrics was special examined on the basis of washing tests.
- the one described below TAV test shows the basic sound release ability of a Additives in the presence of one surfactant, but excluding others, usual detergent ingredients and is therefore independent of the chosen detergent formulation.
- cotton / polyester fabric was mixed with a clay consisting of 33.3% each from varieties 178 / R (ocher), 262 (brown) and 84 / rf (red-brown) from Carl Jäger, Hilgert, evenly coated.
- the types of clay are different "fat"; i.e.

This was done with a Jigger from Arthurs, Krefeld, at 10 meters / minute using of body goods made of 33% cotton and 67% polyester (BW / PES fabric) from Winkler, Waldshut. After 3 Runs were then completely desalted with 600 l Rinsed water once. After that, the wet tissue was in one Stenter dried at 50 ° C and 2 meters / minute drying speed. The clay fabric produced in this way contains 1.76% clay, determined by ashing at 700 ° C, 2.5 h.

- the exact Derivation of the mathematical evaluation was carried out by A. Kud in Tenside, Surfactants, Detergents, Vol. 28, 497 ff (1991).
- the polymers to be used according to the invention were after TAV test described above, cf. Examples 10 to 18. The results obtained are together with the results Comparative Examples 3 and 4 in the table described below 3 specified. As can be seen from this occurs by adding the polymers to be used according to the invention to the aqueous Solution of the nonionic surfactant an increase in the primary washing effect on.
- Example 10 was repeated with the only exception that the test was carried out in the absence of reaction product 1, ie the effect of a surfactant solution containing 80 ppm of the surfactant used in Examples 10 to 18 was tested.
