(54) Detergent for washing (57) Summary of the invention: detergent for washing contains a surfactant of 12-37%, optical brightener 3-5%. water-soluble magnesium salt 1.2-3.0%, zeolite NaA 24.3-28.5%, liquid glass up to 100%. 5 tab.

The invention relates to methods for producing household and technical detergents.

Closest to what is described in the scientific, technical and patent literature is a detergent containing a surfactant, an additive, an aluminosilicate that binds calcium ions dissolved in iodine and water, in the following ratio, wt.%:

The known composition has a large ash when washing the fabric.

The purpose of the invention is to reduce ash when washing fabric.

The goal is achieved in that the detergent for washing containing

a surfactant, optical brightener, aluminosilicate and sodium silicate, as aluminosilicate and sodium silicate contains a mixture of NaA zeolite and water glass, obtained by hydrothermal-alkaline treatment of a mixture of perlite, diatomite or perlite and additionally contains a water-soluble magnesium salt in the following ratio of components, wt.%:

Surfactant 12-37

Optical brightener 3-5 Water-soluble magnesium salt 1.2-3.0 Zeolite NaA 24.3-28.5 Liquid glass up to 100 Characteristics of the starting components:

1. Surfactant - alkyl benzene sulfonate, polyethylene glycol ether of synthetic fatty alcohols of the Ciu-Cie fraction, alkyl sulfonate, fatty acid ester sulfonate, hydroxyethyl VI VJ are used as a surfactant

bath alcohols (syntanol DS-10) TU 6-14-864-85 and carboxylic acid compounds.

2.Optical bleach (TU-6-09-2878-73).

3. A mixture of zeolite NaA and water glass is obtained as follows:

The mixture of tripoli (or diatomite) and perlite (Table 1) is treated at the beginning of the process in an alkaline solution with a concentration of 25-100 g / l N320 Ж: Т (3-Ю): 1. After processing, the liquid phase-liquid glass is separated. An alkaline solution of the indicated concentration is added to the undissolved precipitate and the treatment is carried out under the same conditions: duration is 0.5-4 hours, temperature is 80-95 ° C. Then, sodium aluminate solution is added to the obtained alkaline suspension of the treated precipitate of the rock mixture according to the relevant conditions crystallization of the zeolite, the resulting gel mass is heated to 95 ° C for 10-60 minutes and get a suspension of zeolite NaA.

The zeolite is separated from the liquid phase, dried and calcined at a temperature of 250-300 ° C and used as a component for preparing the detergent composition. The obtained NaA zeolite is introduced into the liquid glass obtained previously heated to 95 ° C.

4. Magnesium chloride technical GOST 7759-73; magnesium nitrate GOST 11088-75.

Technologies for preparing the proposed detergent: to a hot mixture of the product obtained by double hydrothermal-alkaline treatment of a mixture of perlite, diatomite or tripoli with vigorous stirring with heating, a surfactant and an optical brightener are added according to the proposed composition. The resulting composition

dried in a spray fluidized bed furnace at a temperature not exceeding 200 ° C. Examples of the preparation of NaA zeolite and water glass from rocks by hydrothermal-alkaline treatment are shown in Table 2.

The characteristics of the obtained zeolite NaA and water glass are given in table.3. Specific examples of the proposed detergent composition and control examples for substantiating the declared limits of component contents are given in Table 4.

The advantages of the proposed detergent composition in comparison with the prototype and control examples are given in table 5.

As can be seen published table 4, the proposed composition in comparison with the known provides a reduction in ash.

Formula of the invention A detergent for washing containing a surfactant, optical brightener, aluminosilicate and sodium silicate, characterized in that, in order to reduce the ash content of the fabric during washing, the agent contains a mixture of NaA zeolite and water glass as aluminosilicate and sodium silicate, obtained by hydrothermal-alkaline treatment of a mixture of perlite, diatomite or tripoli, and additionally a water-soluble magnesium salt in the following ratio of components, wt.%:

surfactant -12-37;

optical brightener -3-5; water soluble magnesium salt -1.2-3.0; zeolite NaA - 24.3-28.5; liquid glass - up to 100.
