The invention relates to compositions of powdered synthetic detergent (CMC) and is designed for both manual and machine washing and soaking of all kinds of textile products, including non-ferrous, and other household needs.

The trend of development of formulations of synthetic detergents is to develop compounds that combine high ability in relation to contamination of different nature with bleaching ability at low temperatures. It is also desirable beneficial effects of CMC on the fabric, which consists in the lack of inlays, sleek effect, strengthening the brightness of the dyed fabrics and the lack of education of the pellets, as well as reducing the harmful effects of composition on the metal parts washing machines (corrosion and scale formation).

The number of known compounds, to a certain extent to meet this requirement. For example, it is known detergent for washing containing Las sodium, as the nonionic surfactant is ethoxylated ALKYLPHENOLS (neonols), sodium tripolyphosphate, peroxide bleach, carboxymethylcellulose, polycarboxylate "it also", sodium silicate, optical bleach, polyvinylpyrrolidone, TED, the perfume, the product of the interaction of polyoxyethylene isononylphenol, triethanolamine and caustic soda, sodium sulfate and water is (EN 2268293 C1, 20.01.2006, C11D 1/83).

The disadvantages of this detergent is the lack of cleaning ability, high foaming and lack of softness of the products after washing.

Known CMC for washing and bleaching at low temperatures, which contains the anion active and non-ionic surfactants, which are a mixture of Las sodium or its mixture with alkylsulfonates sodium or sodium salts of fatty acids with polyoxyethyleneglycol esters of stearic acid and/or ethoxylated fatty alcohols and, if necessary, with the ethoxylated alkyl phenols, antiresonance - soluble sodium silicate and sodium carboxymethylcellulose, complexing agents - sodium tripolyphosphate, colored granular sodium tripolyphosphate, sodium ethylenediaminetetraacetate (Trilon b) and the sodium salt of nitrilotriacetic acid (Trilon A), percarbonate sodium, tetraacetylethylenediamine (TAED) and useful additives - sodium salt of copolymer of acrylic and maleic acids, enzymes, soda ash, optical Brightener, perfume fragrance, filler is sodium sulfate and water (EN 2177985 C1, 10.01.2002, C11D 1/83).

However, the known detergent has a high content of oxygen bleach and unstable during prolonged storage the AI the powder is compressed, changing the color of the actual funds due to the instability of the composition to oxidation, is clumping, which reduces its quality and detergency of the funds. In addition, the tissues may re-deposition of contaminants and their lack of softener.

The closest technical solution is a synthetic detergent containing, in wt.%: anionic surfactants 10,0-13,0; nonionic surfactants of 2.0 to 3.0; sodium tripolyphosphate 20,0-30,0; peroksigidrat urea 10,0-15,0; carboxymethylcellulose (CMC) of 0.3-0.4; polycarboxylate "it also" 0,1-0,2; liquid glass 3,0-4,0; soda ash 5,0-10,0; optical Brightener of 0.2-0.3; antifoam 0.5 to 1.0; tetraacetylethylenediamine (TAED) 1,0-2,0; 4-methyl-2,6-di-tertbutylphenol (4-methyl-2,6-DTBP) from 0.005 to 0.20; odorant 0,1-0,2; enzymes 0,6-1.0; inhibitor of migration of the dye of 0.05-0.10; water and sodium sulfate to 100 (EN 2230102 C1, 10.06.2004, C11D 1/83).

The main disadvantage of this composition is relatively low cleaning ability, especially at low temperatures, the applicability of the formulation only for washing cotton and linen fabrics. Other disadvantages are the lack of soft-washed fabric and the use of expensive antifoam.

The objective of the invention is the creation of CMC powder with high consumer properties: high the th detergency and bleaching ability at low temperature washing, giving an extra soft washed fabric with reduction of harmful impacts on the metal parts washing machines.

The technical result of the claimed invention is to increase the efficiency detergent with bleaching effect, the removal of different types of pollution, the reduction of temperature regimes washing, as well as reducing harmful effects on the metal parts washing machines.

As well as the claimed CMC may optionally contain percarbonate sodium in the amount of 7.5-19.0 wt.%, tetraacetylethylenediamine (TAED) blue or tetraacetylethylenediamine (TAED) green in the amount of 1.0-2.5 wt.%, sodium tripolyphosphate green in the amount of 1.5 to 2.5 wt.%, inhibitor of migration of the dye in the amount of 0.5-1.5 wt.%, aloe Vera gel in a quantity of 0.05 to 0.15 wt.%

Thus, the totality of the members of the funds ingredients taken in the above quantitative limits, provides a high ability means in relation to various kinds of pollution. The tool does not cake and preserves the stability properties when stored.

As ethoxylated fatty alcohol (nonionic surfactant) can be used Sintana ALM-7 (ethoxylated fatty alcohol fractions of C12-C14(7 moles ethylene oxide)or Sentenal ALM-10 (oxicillin the bathrooms fatty alcohol fractions of C 12-C14(10 moles ethylene oxide)), or Neodol 457 (ethoxylated fatty alcohol fractions of C14-C15(7 moles ethylene oxide)or Neonol AF 9-12 (is a technical mixture of polyethylene glycol ethers of polyoxyethylene monoalkylphenols-based propylene trimer), or Slovaca 257 (ethoxylated fatty alcohol fractions With12-C15(7 moles ethylene oxide)), produced by both domestic and foreign industry.

A mixture of Las sodium and surface-active substances (surfactants): cavasola, or cintanya, or neodol, or neonols form the basis of the scrubbing part synthetic detergent funds.

Using polycarboxylate based on acrylic acid, such as Sokolan RA 30 CL (sodium polyacrylate) or Sokolan SR (sodium salt of a copolymer based on maleic acid and acrylic acid), or Acusol 497 N (sodium salt of a copolymer based on maleic acid and acrylic acid), or it also AMK-10 prevents re-deposition of inorganic salts on the fabric, to improve the appearance of products, dispersing pollution and to increase the ability of the tool.

Intermediate CMC-turquoise pellets attached powdered CMC additional cleaning and whitening ability, allows to obtain the CMC with inclusions turquoise CEE is a, that improves the appearance of the CMC. Intermediate CMC contains as a surfactant Las sodium (sulfonic acid). Also contains sodium tripolyphosphate and sodium carbonate (soda ash), which are introduced to increase detergency funds and as logomachy components. Soda ash also amylee fatty pollution, complements and enhances the cleaning effect of the surfactant. Sodium tripolyphosphate, prevents the formation of scale on metal parts washing machines and softens water solution.

Liquid glass in the presence of complexing agents enhances the ability of suspended polar contaminants and prevents their re settling on the fabric, enhances the effect of soda ash to neutralize the grease. Cyan dye Cinelux BMS (trading company Ciba-Geigy) allows to achieve a higher whiteness and to give granules turquoise color. The sodium sulfate is used in medicine as filler.

When testing different formulations of semi-CMC-turquoise pellets revealed that the best qualities of the semi-product having the following composition, wt.%:
