The invention relates to the production of synthetic detergents. Can be used for washing textiles from cotton, linen and synthetic fabrics in the home and in industrial laundries.

Known detergents containing anionic and nonionic surface-active substances (surfactants), crystalline zeolite, soda, silicates, water-soluble polymer, sodium sulfate, perfume, water [U.S. Pat. Germany No. 3644808, IPC C 11 D 3/20, 1993, U.S. Pat. U.S. No. 3962149, IPC C 11 D 3/20].

Also known pasty detergents containing synthetic fatty acids, surfactants, bleaches, water, mineral supplements, for example, alkylsulfate sodium, ["Willow" - OST 6-15-543-87] sodium chloride ["Lily" - GOST 22567-15-96].

But known detergents have an unpleasant odor and low foaming and washing capacity.

To eliminate the unpleasant smell of detergent add fragrances perfume, and to improve detergency and additionally enter in the composition of organic and inorganic additives.

Known detergent for washing, additionally containing silicate type of smectite in the amount of 3.0 to 15.0% [U.S. Pat. Germany No. 3702067, IPC C 11 D 3/20, 1984] and 2.0-10.0% of notinitialized [U.S. Pat. Germany No. 3709931, IPC 11 D 3/30, 1984].

The disadvantages of these methods are the high content of silicates in detergent that Pref is the CIO to poor solubility tools in the water, low washing ability, in addition, the lack of production of layered silicates domestic chemical industry, high cost abroad make it impossible to release affordable detergent.

Also known Laundry detergent comprising anionic and nonionic surfactants, ethoxylated fatty acid, CMC, complexing agents, mineral supplements, enzymes, optical brighteners, defoamers, perfume, sleek additive - bentonite clay [U.S. Pat. UK No. 2207144, IPC C 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, such as sodium sulfate, sodium carbonate and sodium bicarbonate, liquid glass, carboxymethylcellulose (CMC), bleach, water [U.S. Pat. Of the Russian Federation No. 2081156, IPC C 11 D 3/20, 1994, U.S. Pat. Of the Russian Federation No. 2089602, IPC 11 D 1/12, 1995].

But these detergents also provide a relatively low ability and do not provide sufficient softness of the washed product.

Also known detergent containing surfactants, soluble complexing agents - sodium tripolyphosphate, useful additives - sodium bicarbonate and carbon dioxide, sodium chloride, fillers - sodium silicate, is Ulfat sodium, antiresonant - CMC, optical brighteners, perfume, antifoam, water [U.S. Pat. Of the Russian Federation No. 2100428, IPC C 11 D 3/20, 1996].

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: caking, clumping, which generally reduces its cleaning ability.

Known detergent according to the patent of Russian Federation №2177986 containing a high percentage of soda ash, negatively affects the skin, causing allergic reactions that is especially true with hand washing, and is not a high washing capacity.

Known detergent containing anionic and nonionic surfactants, zeolite, modifying additives, such as sodium tripolyphosphate, sodium carbonate, components bleaching, sodium sulphate, CMC, antifoam [U.S. Pat. Of the Russian Federation 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 corrode washing machines, if produce native art is RKU, low propulsively tissues that when you rinse linen leads to a large consumption of water.

The closest technical solution prototype is a detergent containing anionic and nonionic surfactants, antiresonant - sodium silicate, carboxymethylcellulose, and sometimes sodium citrate, complexing agents - sodium tripolyphosphate, useful additives - sodium carbonate, sodium bicarbonate, optical Brightener, the antifoam polivinilpirolidon, fillers - sulfate of sodium and water in the following ratio of components, wt.%:

[Pat. Of the Russian Federation No. 2167190, IPC 11 D 1/83, 3/10, 3/075, 2000].

The disadvantages of this detergent are insufficient softness of the washed fabric, not a high detergency and high consumption of dobrogost asego surfactant sulfonic acid, which generally increases the cost of detergent.

6. Soda ash- 5,0-10,0
8. Optical bleach- 0,2-0,3
9. Product interaction

Heated the reaction mass to a temperature of 70°and incubated for 8 hours the reaction Product is a salt, which are evaporation of the reaction mixture. Loose salt is washed with an organic solvent, filtered and dried to constant weight at a temperature of the boiling point of the solvent. In the end you get to 70.8 g (88%) of product, representing with the Oh white powder with a melting point 283-286° Since, well soluble in water and alcohols C1-C4insoluble in hydrocarbons.

Getting detergent

In a glass reactor equipped with a jacket heater, load the calculated amount of water; the product of the interaction of ethoxylated isononylphenol, triethanolamine and sodium hydroxide; herstory, which is prepared separately by mixing the stated amount of surfactant, liquid glass, water, CMC, "Acremon", optical Brightener, antifoam at room temperature. Then into the reactor with constant stirring upload sodium sulphate, soda ash and/or sodium bicarbonate, sodium tripolyphosphate, and sodium chloride. Heated to a temperature of 60-80°and at this temperature was kept for 20-30 minutes. Next, the resulting composition is dried to a moisture content of 5-15%. The dry product is ground and then add the flavoring.

Examples of the claimed detergent composition shown in table 1, the figures in table 2.

Use detergent containing the claimed components in a larger ratio than the claimed impractical in smaller - not achieved the claimed technical result.

Ability is determined by standard methods GOST 22567.15-95 as the ratio of the degree of removal of the contamination of the test solution of detergent to step shall neither relieve the pollution solution composition comparison on artificially contaminated pigment-oil composition of cotton fabric at a temperature of 80° With in a laboratory washing machine "Linetext+".

Sleek effect is determined by RD 6-40-00209645.2.1.-92.

Based on data presented, we can conclude that the claimed synthetic detergent will expand the range of high-quality CMC has high consumer properties, not inferior in detergency analogues and prototype. Additionally, washed the proposed composition of the detergent and the fabric has a higher score softness than fabric, washed by means of the prototype.
