You are too degradable according to the decrease in dissolved oxygen in the closed Bottle test and according to the modified SCAS test, cf. R. Wagner, Methods for Testing the Biochemical Degradability chemical substances, Verlag Chemie, Weinheim 1988, page 62.
- reaction products described above or their alkali, ammonium and alkaline earth metal salts are added to phosphate-reduced or phosphate-free detergents and cleaning agents. In most cases the amount applied is Reaction products 0.1 - 30 wt .-%, based on the washing and Cleaning supplies. Under reduced phosphate detergents such terms are understood as no more than 25% by weight of phosphate, calculated as sodium triphosphate. Most phosphate-free detergents contain sodium aluminum silicate (Zeolite A).
- the implementation products from the components a) and b) or their salts are preferably used in amounts from 1 to 20% by weight, based on the detergent or cleaning agent formulation, used. 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 alkali silicates include, for example amorphous sodium disilicates into consideration, which are described in EP-A-0 444 415 are described, as well as crystalline layered silicates, which according to EP-A-0 337 219 contained in detergent formulations as a builder are and according to EP-B-0 164 514 for softening water used, and sodium silicates by draining from sodium silicate solutions and drying up to water contents of 15 to 23, preferably 18 to 20 wt .-% are available.
- Sodium aluminum silicates (Zeolite A) can be used in amounts up to 50% can be contained in detergents.
- the detergents can optionally also contain a bleach, e.g. Sodium perborate, which if used in Amounts up to 30 wt .-% in the detergent formulation can be.
- a bleach e.g. Sodium perborate
- 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.
- the K values of the neutralized reaction products were H. Fikentscher, Cellulose-Chemie, Volume 13, 58 to 64 and 71 to 74 (1932) in aqueous solution at a temperature of 25 ° C and one Concentration of 1 wt .-% at pH 7 on the sodium salt of the polymers certainly.
- the quantities of maleic anhydride and protein given in Table 1 are introduced into a 500 ml pressure-tightly sealable reactor which is equipped with a stirrer and heated to a temperature of 140 ° C. under pressure for 4 h with exclusion of moisture. A solution or a slurry of the reaction product is then obtained in molten maleic anhydride.
- 1 l of anhydrous acetone is added after the reaction mixture has cooled, the mixture is stirred for 3 h and filtered. The filter residue is then extracted with acetone in an extractor for 4 h and then dried in vacuo.
- the reaction products listed in Table 1 are obtained, which are characterized by means of the K value and the acid number.
- the implementation products were used for the technical tests 1 to 10 converted into the sodium salts in which 10 g of Stir powdery products in 100 ml of water and add neutralized by 10% aqueous sodium hydroxide solution until no more sodium hydroxide solution was used and an aqueous solution or slurry of the reaction products with a pH was between 7 and 8.
- the clay dispersion was carried out as described below Clay dispersion test (CD test) assessed.
- Finely ground china clay is used as a model for particulate dirt SPS 151 used.
- 1 g of clay is added with the addition of 1 ml 0.1% sodium salt solution of the polyelectrolyte in 98 ml of water Intensely dispersed for 10 minutes in a standing cylinder (100 ml).
- 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.
- the clay mixture was in the form of a 20% Suspension in deionized water with vigorous pumping around the Suspension brought homogeneously onto the tissue. 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 tissue thus obtained is pre-measured via color strength and in Classes divided. Be as a color strength range for a class 10 units set arbitrarily. The color strength range of everyone The blended fabrics used are between 260 and 340 color strength units. A washing series consisting of 6 washing attempts, is made of only one class with soiled fabric carried out.

- Test concentration of the polymer 80 ppm Dirty tissue 5 g clay fabric ( ⁇ 30.5 cm x 8 cm)
- White tissue or clean tissue 5 g PES / BW fabric ⁇ 30 cm x 8 cm
- weighting factors for eye irritation ( X 10 ( ⁇ ) + Y 10 ( ⁇ ) + Z. 10 ( ⁇ )) are shown in the table below: ⁇ (nm) Weighting factors ( X 10 ( ⁇ ) + Y 10 ( ⁇ ) + Z. 10 ( ⁇ )) 400 0.1071 420 1.1984 440 2.4131 460 2.1759 480 1.1062 500 0.6831 520 0.9402 540 1.3525 560 1.7025 580 1.8831 600 1.7823 620 1.2544 640 0.6114 660 0.2129 680 0.0568 700 0.0133
- the weighting with the eye irritation function of humans should be Weight slight yellowing of the fabric more.
- 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.
