The invention relates to detergents and can be used both for manual and machine washing and soaking of all kinds of textile products, including non-ferrous, and other household needs.
Known composition for washing clothes containing Soaps of fatty and resin acids, plasticizers, and anionic surfactant protein, water [A.S. USSR №345192, IPC 11 D 9/02].
But this composition does not contain useful additives such as complexing agents, antiresonance, and other inorganic salts which would ensure quality usteriana dirt.
Known detergent composition for washing clothes, containing water, soap, surfactants and soda ash, and metasilicate sodium. As synthetic surfactants used alkylsulfonate sodium [A.S. USSR №857259, IPC 11 D 9/02].
The disadvantages of this structure include high alkalinity, which causes unwanted allergic reactions, particularly skin irritation, low ability, as well as significant inlay tissues due to its high content in detergent sodium carbonate and precipitation of calcium Soaps.
Also known Laundry detergent comprising anionic and nonionic surfactants, ethoxylated fatty acid, CMC, complexing agents, mineral supplements, enzymes and optical bleach the teli, defoamers, perfume, sleek additive - bentonite clay [Patwariabathe No. 2207144, IPC 11 D 3/12, 1992].
But this means, as above, has insufficient washing capacity.
Known washing Laundry detergent containing anionic and/or nonionic surfactants, sodium tripolyphosphate, a mixture of inorganic additives, for example, sodium sulfate, sodium carbonate and sodium bicarbonate, liquid glass, carboxymethylcellulose (CMC), bleach, water [Path No. 2081156, IPC C 11 D 3/20, 1994].
But this tool also has a relatively low washing ability and does not provide sufficient softness of the products after washing.

The main disadvantage of the known detergent is insufficient washing ability tools and universalist, i.e. the impossibility of its application for all types of underwear, especially for color, resulting in the flushing of the paint. In addition, during long-term storage of detergent is the deterioration of its quality: slii haemost, the clumping, which generally reduces its cleaning ability.
Also known detergent containing anionic and nonionic surfactants, zeolite, modifying additives, such as sodium tripolyphosphate, sodium carbonate, components bleaching, sodium sulphate, CMC, antifoam [Path No. 2182164, IPC 11 D 3/39, 3/12, 3/06, 1997].
The main disadvantage of the known tool is the high content of zeolites and surfactant, which leads to higher detergent, and, in addition, keep a large amount in the composition of sodium sulfate correlates washing machines, produce if machine washing, as well as low propulsively tissues that when you rinse linen leads to a large consumption of water.
Known detergent containing soap powder, soap sodium on the basis of higher fatty acids, surfactants, complexing agents, sodium silicate, enzymes and optical bleach, polyvinylpyrrolidone, sodium chloride, antifoam, flavoring and sodium sulfate [U.S. Pat. Of the Russian Federation No. 2167193, IPC 11 D 9/04, 9/38, 9/08, 9/26, 2000].
The main disadvantages of this tool should be considered a relatively low ability and a lack of whiteness of the fabric after washing.

But this cleanser provides for the use as a peroxide bleach only peroksigidrat urea that in case of shortage of the latter may cause difficulties with the supply of raw materials. Moreover, in this case, it is not always possible to achieve the desired result in the bleaching of fabrics.
Friends and the lack of soft-washed fabric and the use of expensive antifoam.
The technical task of the invention is to improve the washing steps and providing additional soft-washed fabric.

In the proposed washing compositions as surface-active substances used linear Las sodium (sulfonic acid) STP 00204872-15-P or a mixture of the sulfonic acid soap and fatty acids, including acids W is rnie synthetic fraction 17-C20according to GOST 23239-89 and caustic soda technical GOST 2263-79 for the saponification of fatty acids or the sodium salt carboxymethylamino of ethoxylate of isononyl-phenol (sinterol) STP 00204872-17-P, which has the General formula: R-C6H5-O(C2H4O)nCH2COONa, where: R - isononylphenol; n - 6,10,12.
As the nonionic surfactants used ethoxylated ALKYLPHENOLS (neonols) TU 2483-077-05766801-98 or polietilenglikolya synthetic esters of fatty alcohols (fatty alcohol ethoxylates) TU 6-14-864-88, THE 6-14-577-88.
To reduce foam in the CMC formulations typically use silicone defoamers. The antifoam is one of the relatively expensive raw materials, which affects the cost of detergent.
As nonionic surfactants have low foaming, the use of ternary mixtures of surfactants: nonionic surfactants, anionic surfactants and Soaps will help to achieve maximum reduction of the foam without the use of expensive antifoam at their high detergency.
It is known that the washing process was appreciably affected by the measure of the concentration of hydrogen ions (pH). The most effective usteriana takes place in an alkaline medium at pH 9-11. Regulator alkalinity in detergents are usually used additives such as soda and Tripol is sodium phosphate.
However, excessive sodium causes inlay and POSELENIE tissue in the process of repeated washing and the high phosphate content in CMC adverse from the point of view of ecology, as when ingested phosphate in the water bodies eutrophication occurs last.
In the inventive detergent is suggested to use the product of the interaction of polyoxyethylene isononylphenol, triethanolamine and sodium hydroxide, which is an alkaline agent and an activator of the washing steps.
In connection with the foregoing, the joint use of these supplements will help to reduce the amount of soda ash and sodium tripolyphosphate, as well as to increase the activity of surfactants and to increase the ability of the tool.
As complexing agents suitable for use in the present invention, provided inorganic P-containing detergent builders, for example, tripolyphosphate according to GOST 13493 or THE 2148-037-00194441-02, or THE 2148-095-43499406-98, or THE 113-00-05759020-25-95).
As the peroxide bleaches are used peroksigidrat urea (TU 2136-111-25556678-2001), peroksoborat sodium (TU 6-02-1187-79 with ISM. 1,2,3,4,5,6), percarbonate sodium (TU 2144-001-24345844-2002).
The presence of a peroxide bleach achieve greater white fabric after washing, protection paint fabrics, and in addition and dezinficiruy the action.
In addition, generated by decomposition of peroksigidrat urea has a beneficial effect on the fabric, reducing its destruction.
2,6-ditretbutyl-4-dimethylaminomethylphenol (2,6-DTB-4-DAMP) is an effective stabilizer wide steps for polymeric materials, rubber chemicals and hydrocarbons. Its presence in the composition of the detergent composition will prevent collapse of the peroxide and organic compounds by a radical mechanism containing unsaturated and hydroxyethyl group, thereby to improve the resistance to oxidation and to preserve the ability, the bleaching properties and other quality indicators derived detergent for a long time.
Used 2,6-DTB-4-DAMP - powdered or flake product from light yellow to orange color, is produced in accordance with TU 38.103368-94.
The presence in the formulation of polyvinylpyrrolidone will improve the appearance of the product, saves paint on colored fabrics, not allowing them to slip away, and in General, gives the product a more pronounced updated.
The soluble sodium silicate (glass sodium) is used according to GOST 13078-81 or GOST 13079-93 or THE 2145-026-00204872-2002.
Sodium carbonate (soda ash) used according to GOST 5100-85 for water softening and regulating the pH of the environment.
The sodium sulfate is used according to GOST 21458-75 or GOST 6318-77,or THE 2141-084-00209527-99, or THE 21-249-00204168-92.
As antiresonant use carboxymethylcellulose technical (CMC) brand 70/300, 75/400 or 85/700 on THE 6-55-40-90, or THE 2231-017-32957739-02 or Cancel 0(1) TU 2231-001-35193780-96 or THE 2389-011-262839127-96.
The presence in the composition of the bleaching activator of TAAD will improve the quality of washing and to ensure a more complete removal of dirt from the fabrics, and also to give a more pronounced white products from white fabrics. In addition, will allow you to wash at lower temperatures (40-60°).
TAED use imports.
As use perfumes fragrances for Soaps and detergents, for example, on THE 64-19-137-91, or THE 10-04-16-31-87, or LV-05-94 or other commercially available perfumes.
As optical brighteners use bleach, for example, Belfor KD-2 6-14-423 on THE 6-14-423-87, or THE 6-38-05800142-174-95, or THE 6-38-05800142-154-94 for cotton fabrics, or, for example, Relux OTHERS (Czech Republic) for synthetic and mixed fabrics, or other commercially available optical brighteners.
The use of Acremon" prevents re-deposition of dirt and reduces water hardness and improves the particle size distribution and flowability of the detergent. "It also" use THE 2492-001-46270704-2001. It is a compound of the following formula
In addition, the joint content in the composition of Acremon and 2,6-DTB-4-DAMP probably show any synergistic effect, which does not absorb moisture from the environment, especially during long-term storage, thereby maintaining the dispersion, color and all operational properties, and ability tools for long term storage.
Enter in the inventive detergent sodium chloride gives extra softness washed linen. In addition, the sodium chloride is the electrolyte lowers the critical concentration of micelle formation, helps to achieve maximum surface activity at minimal cost surface-active substances. Use according to GOST 13830-91 or THE 9192-027-002-04872-95.
