    one
    The invention relates to a compound of formulations containing mainly non-ionic surfactants with short ethoxylate chains or anionic with the addition of the usual structural components, bleaching agents, fillers and other components.
    A washing agent is known that contains an anionic, non-ionic or amphoteric surfactant, various auxiliary substances and an additive, which is a water-soluble alkali metal salt of the condensation product of alkylphenol with salicylic acid and formaldehyde, used as an inhibitor of darkening fl.
    However, this tool has insufficient fluidity and low bulk density.
    The aim of the invention is to improve the flowability and increase the bulk density.
    This goal is achieved by the fact that the wet detergent containing a surfactant, an auxiliary substance and an additive according to the invention contains a water-insoluble additive
    the polymer of urea and formaldehyde with a specific surface area of 15-30, and as a surfactant, the agent contains non-ionic and / or anionic substances in the following ratio of components, wt.%:
    Non-ionic surfactant 5-50 Anionic surfactant 5-25 Urea and formaldehyde polymer with a specific surface 15-30 MVr 0.05-2.5 Substrate Up to 100 As non-ionic surfactants can be used: polyglycolic and fatty monoesters alcohols, fatty acids, silky alkylphenols, N, N-polyethoxylated fatty amines with a long chain, M, H-n6 lytoxylated amides of fatty acids with a long chain. Can also be used mixtures of these soeneny. Suitable adjuvants are salts (one or more) of alkali metals that are soluble in water, for example carbonates, borates, phosphates, polyphosphates, bicarbonates and silicates. Water soluble alkali metal or ammonium salts can be used, for example, ethylene diamine sodium, potassium and ammonium tetraacetate. Bleaching agents are also added, for example, percarborate and alkali metal persulfate, alkali metal perborates, inert inorganic salts are also used. As anionic surfactants, soaps or synthetic surfactants are used, for example alkali metal or ammonium salts of fatty carboxylates, sulfonates or sulfates, and alkali metal alkanesulfonate or alkali metal O-olefin sulfonate. The polymer introduced as an additive has a molecular weight greater than 1000. Examples of such polymers are polcondensation products, in particular, polycondensated aminoplasts, such as urea-formaldehyde polymers. The polymer particles are spherical with a diameter of 0.1 μm or less. They form agglomerates with a diameter of 3-6 microns, preferably 4-6 microns Especially suitable are condensation products of urea and formaldehyde, obtained in the presence of sulfamic acid or ammonium bisulfate. Urea-Formaldehyde condensation products are obtained, for example, by converting an aqueous solution of preliminary urea condensation and formaldehyde, sometimes in the presence of a protective colloid, in a gel with the addition of sulfamic acid or a water-soluble ammonium sulfate hydrogenation product of the formula: IR-NH SO where R is m is hydrogen or an organic radical which does not reduce the solubility in water, such as alkyl, cycloalkyl, hydroxyalkyl, aryl or aralkyl, with a molar ratio of formaldehyde to urea in the gel formation time of 1 followed by pulverizing, drying and discharging the gel sheniem agglomerates. When protective collars are used, it is desirable that the molar ratio of formaldehyde to urine be greater than 1.2. Foam stabilizers, suspending agents, optical illuminators, enzymes, and weak fragrances are also added to detergent formulations. Suitable foam stabilizers are long chain acanolamides, such as coke nut monoethanolamide. Suitable suspending agents are carboxymethylcellulose. The following types of clarifiers can be used as optical brighteners: triazinyldiaminostilbendisulfonic acids, aminocoumarins, parasolines, stilbylnaphthatriazoles, imidazolones, benzidine sulfonisoxazoles, distyryl diphenyls, dibenzimidazoles or their derivatives. Commonly used enzymes include enzymes containing predominantly protease derived from the spore-forming bacteria Bacillus subtilis. Citrus or pine based perfumes are suitable. Prepare the agent by mixing the polymer with other components. The polymer can be added to the aqueous suspension. components before drying spray the entire mass. Examples 1-8. Separate samples of powdered detergent (Detergent A) based on non-ionic surfactants and non-ionic alkanolamides are mixed with the condensation product of urea and formaldehyde (product A) in the following proportions,%: O, 0.05.0.1, 0.25, 0.5, 1.0, 1.5, 2.5 and 5.0. Product A had the following characteristic: Diameter of primary particles, µm0.1 Diameter of agglomerates of these particles, µm 4-6 Specific surface of particles, m / g20 Specific gravity, g / cm 1.45 The displacement is performed in a fiber barrel on a roller mill. Then the sample is placed in two large bags for wet powder and stored at a relative humidity of 65%, and also at a relative humidity of 93%, respectively, for 35 hours. A) Influence on fluidity. Fluidity is determined; when filling a large package for detergent powder (6.75-10.0 "17.8 cm) to a point 6.35 cm from the top of the package, with the result that each package contains on average 380 g of powder. The percent turnover is then measured at different angles. . Each sample was tested twice as follows: the bag was rotated twice to loosen the aggregates; the bag is placed in a test apparatus and rotated at the required angle, collecting the powder, which flows out after 30 s, weigh the outgoing powder. The test results are shown in Table. one.
    Table
    The results show that the optimum content of product A is equal to 1.5%, the humidity has little effect on the fluidity, with the exception of high content, i.e. 5% of product A, when% effluent decreased at. b) Effect on the action of a fluorescent whitening agent (FOL). The effect of PAA of a non-ionic detergent containing no product A is compared with the same effect of the proposed detergent composition under the following conditions: The substrate is a mercerized cotton atlas that does not contain FOA temperature, the duration of washing is 15 minutes each, the finishing bath module is 20: 1. Liquid - preheated water, to which 5 g / l of detergent sample in powder form was added just before washing the sample. the illustration is carried out after 1.5 and 10 consecutive washes. After intense rinsing, drying and conditioning at 20 ° C and 65% relative humidity, the total fluorescence Fj of each sample is measured using the average of 10 indicators on the satin surface of the duplicate sample. Samples are also examined visually when comparing with Tsiba Geigi's white fabric cloth. This scale consists of 18 pieces of cotton fabric treated with a fluorescent whitening agent; these pieces of fabric form a series of optically equidistant stages numbered from tens to 70 to 240. 70 corresponds to the whiteness of cotton fabric subjected to complete chemical bleaching, but not treated with a fluorescent bleaching agent, 240 corresponds to very intense whiteness achieved with the help of active bleaching agents . The results are shown in Table. 2.,. Table 2 Without the product A310 190 459 2Ч-0-, 492 240 1.5% of the product A308 190 459 240 394 240 These results show that the addition of 1.5% of the product A does not affect the effect of the fluorescent bleaching agent with the sales agent of a non-ionic detergent. c) Effect on detergency and soil repellency. The detergent and soil repellency capabilities of a prod- ect non-ionic detergent containing 1.5% of product A are compared with the same detergent properties of a product not containing product A under the following conditions. The substrate is contaminated cotton fabric and pure cotton poplin that does not contain FOA. Temperature, washing time 30 minutes, finishing bath module 20: 1, liquid - heated water, to which 5 g / l of detergent sample in powder form was added just before washing the samples. The treated samples are rinsed thoroughly and dried. The whiteness of the sample is measured with a device for measuring the color difference, taking the average of four readings (two pairs at 90 ° C) as the result for L, a and b. L - total luminescence, a and b - show the position in color coordinates. When comparing these quantities with the values obtained before the treatment, the difference in detergency (loss of the gray shade of the fabric) and: gray repellency: ability (increase in gray from the pure cotton poplin) is determined. The results are shown in Table. 3 Table 3 .- ives - -.-- If Indicator B (100 - 2) + f + 2.2542 + 2) Washing capacity Without product A 34.872 55.463 20.591 34.675 56.056. 21.481 Gy repellent ability Without product A 74,708 73,480 -1,222 1.5% of product A 74,754 73,769 -0,985 Difference B, 0.5, visually noticeable. These results show that the detergent and soil resistance of the commercial detergent does not change with the addition of 1.5% of the product - d) Effect on withdrawal efficiency. Bleaching efficiency 7 ° rinsing) - B (before rinsing). B (clean poplin) - B (before washing) the bleaching efficiency of a commercial non-ionic detergent containing 1.5% of product A is compared with the bleaching efficiency of detergent that does not contain product A under the following conditions. The substrate is cotton tea polluted with tea. Tea-soaked tissue was prepared as follows. 20 g of the tea leaf was extracted 2 hours in 800 ml of water at. The solution was filtered under vacuum and the residue was again extracted with 200 ml of water for 0.5 h at. After re-filtering, the filtrate was added to the original filtrate and the volume was DRAWN up to 1000 ml. Prepared 9 samples of mercerized cotton poplin that does not contain FOA. A moody specimen weighs 5 g. These specimens are treated with tea extract in closed dye bars for 2.5 hours with a 24: 1 finishing bath module. Samples incubated in the dark for 17 hours, ensuring complete immersion of tissue in the extract. The liquid is heated again to 100 ° C and the treatment is continued for another 2.5 hours at this temperature. Samples are rinsed with water and dried for 20 hours to age the colorant. The free color is removed by washing with 5 g / l of a synthetic anionic detergent, not with stainless fool and a bleaching agent, for 20 minutes with a 20: 1 finishing bath module, and then rinsing the samples and drying at 70 ° C. Washing time 15 min. Finishing bath module 20: 1. Liquid - heated water, to which 5 g / l of detergent sample in powder form was added just before washing the samples. The treated samples are rinsed thoroughly and dried. The whiteness of each sample is measured with a device for measuring the color difference, taking the average of 8 readings (four pairs at 90 ° C) as the result in each case for L, a and b. When comparing these values with the values obtained before processing and the values for pure cotton poplin, the bleaching efficiency values are obtained. The results calculated by the Formula are given in Table. 4. Table4
    These results indicate that the bleaching efficiency of a commercial non-ionic detergent is slightly improved by adding 1.5% product A.
    e) Effect on dark colored tissues during washing.
    The effect on dark-colored fabrics of a commercial non-ionic detergent containing 1.5% of product A is compared with the same effect of detergent not containing product A under the following conditions.

The temperature is 60 ° C, the duration of washing is 15 minutes, the module of the finishing bath is 20: 1, the liquid is heated water, in which 5 g / l of detergent sample in powder form was added just before washing the samples.
    The illustration is performed after -1 and 5 consecutive washes.
    The treated samples are lightly rinsed, dried and compared visually for the presence of chalk caused by product A deposition.
    The results of these tests on both tissues show that the addition of 1.5% of product A does not cause the washed tissue to grind.
    e) Effect on bulk weight of powder.
    The volumetric weights of powder samples containing 0, 1.5, and 2.5% of product A are determined using an automatic apparatus.
    A portion of a sample weighing 20 g is placed in a glass cylinder equipped with a sealing device. The cylinder is installed in the apparatus and the contents are compacted 50 times, and the volume of the compacted powder is also noted.
    The results are shown below.
    Content of production - Volume weight, that And,% .g / ml
    0.51 0.53 0.56
    These results indicate that the volume weight of the resulting powder increases with the addition of product A. The increase reaches approximately 4% with the addition of the optimum amount of product A.
    g) Effect on the selection of powder oil during storage.
    Conventional bags of nojxxuKa, made of separated cardboard, 550 µm thick, weighing 340 g / m, are filled with powder samples containing 0% and 1.5% of product A. The samples are stored in the laboratory for 8 weeks. .
    The bags are then visually examined to determine the oiliness on the outer surface of the bags, which is assessed according to the following scale:
    0- bag oil does not drop
    1- traces of oiliness
    2- light oiliness
    3- moderate oiliness
    4- Strong oiliness. The results are shown.

    65 These results show that product A significantly increases its fluidity when mixed with a detergent suspension having the above-mentioned composition and that the optimum amount of product A is 1.5%. Examples 35-52. Powder detergent B, produced on an industrial scale and considered in Examples 33 and 34, mix different proportions as shown in Table. 7, with industrial products of urea-formaldehyde condensation A, B C, D and E products with a specific surface value are used, B - 7, C - 15, A - 20, D - 30. E - 60. Mixing products t in a fiber barrel on a roller mill for 18 hours. Then each sample is kept for 36 hours at 20 ° C and a relative humidity of 93%. The yield is then evaluated as described in Examples 1-8, with the% El measured at an angle of 120. The results of determining the% draining are also given in table. 7. Table 7 Continued table. 7 Results table. 7 shows a significant effect on the maximum for the 1.5% product C, A and O content with a specific surface area of 15, 20 and 30 m / g. There is also a slight effect on the maximum when using 1.5% of product B with a specific surface of 7, but an increase in yield is slightly pronounced when compared with the use of products having a specific surface of 15-30. When using products with a specific surface above. 30, for example, product E with a specific surface area of 60 m Vr, no effect on the maximum is observed. For the preferred range of 15-30 inVr, the effective amount of the condensation product of urea and formaldehyde is 0.05-2.5 wt.% Based on the total weight of the detergent composition. Thus, adding highly dispersed water-insoluble organic polymer improves flowability, reduces packing oiling during storage, increases bulk density, and does not deteriorate the working properties of the finished detergent composition. In addition, the proposed detergent compositions are superior to well-known detergents in terms of achievable fluorescent whiteness, detergency, soil repellency, bleaching and chalking efficiency, i.e. the deposition of a flow improver on dark-colored fabrics during washing.
