Description

The invention relates to the production of household chemical goods, in particular to synthetic detergents that are safe for the ecology of water bodies.

Such means should have detergency in hard water, prevent the formation of water-insoluble precipitates with calcium and magnesium salts of hard waters, do not contain salts of polyphosphoric acids harmful to the ecology of water bodies and wastewater treatment plants, and also have reduced foaming for use in washing facilities. machines of any designs.

The aim of the invention is to increase the detergency of the agent, reduce foaming and environmental impact.

In tab. 1 shows examples of compositions of a phosphate-free detergent (1-14).

In tab. 2 presents data on detergency and foaming (examples 1-14) in comparison with known detergents.

As a nitrogen-containing surfactant, the compositions contain:

(laundermeter) erase samples of standard-contaminated tissue by the known method, with detergents at a temperature of 20, 50 and 80 ° C and a concentration of 0.25 wt.%.

In tab. 1 shows examples of detergents.

Solutions are prepared in standard water hardness — 5.35 mEq / L.

The results of detergency are given in table. 2

As can be seen from Table 2, the washing ability of the proposed agent with a nitrogen-containing surfactant content in the range of 1.7-10.9% is comparable and in some cases exceeds the washing ability of known detergents (optimal examples 5-8).

The foaming capacity is determined using a Ross-Miles instrument according to a known method. In water of medium hardness, 5.35 mEq / L at 20 and 50 ° C.

From the data table. 2 that the foaming ability of the proposed detergent is 1.5-2.0 times less than the known detergents of Bio-est and Oka.

Conducted tests on the graying of fabric after 25 washes showed satisfactory results compared to Bio-Est detergent.

The tests for the toxicity of compositions containing nitrogen-containing surfactants showed a low toxicity of LDgjj of 2-3 g per kg of live weight of experimental animals.

The proposed detergent for washing textile materials has the following advantages over the well-known: efficiently without the use of salts of polyphosphoric acids, has a low foaming capacity without the use of defoaming surface-inactive substances, has a lower toxicity, has no harmful effect on the environment, can be used in all types of washing machines.
