(54) MEANS FOR WASHING TABLEWARE

The invention relates to household chemicals, in particular, compositions for washing dishes: porcelain, fessou, ceramic, crystal, glass and tableware.

The known composition for dishwashing, containing 10-40 wt.% Of fatty acid esters and polyethylene glycol and pH stabilizers, for example,%: water-soluble citrate 0.03-3, urea 3-10, ammonium chloride. About 1-1, with a ratio of citrate: urea 0.05-4: 10 and citrate: chloride ciMMO 0.1-10: 1 1.

The disadvantage of this remedy is the deficiency of sodium citrate.

A means is known that contains a mixture of anionic surfactants with non-ionic, disinfectants and other active additives. Alcohol has been added to reduce viscosity. In addition, to improve the compatibility of the components, the agent contains hydropropanol, α-xylene, or cumene sulfonates in the form of alkali metal salts G2.

The disadvantage of the tool is the use of expensive hydrotropes in its composition.

Closest to the proposed technical essence and composition of the components is dishwashing detergent containing sodium or ammonium salt V shkylpolyoxyethylene sulphate, polyethylene glycol-115 or polyethylene glycol ether of monosan tamolamides of synthetic fatty acids -id, Chintamide-5), ethyl alcohol,

10 carbamide, sodium chloride, perfume and water 30 ..

This agent has a low detergency and is opaque in appearance.

15 almost colorless liquid.

The aim of the invention is to increase the detergent properties of the agent.

The goal is achieved by the fact that the dishwashing detergent,

20 comprising a sodium or ammonium salt alkilpolioksietilensulfata, nonionic surfactants, urea, a perfume and water, contains as nonionic surfactant a polyethylene glycol 25 ether monoethanolamides of synthetic fatty acids (or polioksieti lenglikolevy ester synthetic oil:. GOVERNMENTAL alcohols in a weight ratio to the sodium or ammonium salt al30 kilopolyoxyethylene sulfate, equal to 1: 1 and additionally contains potassium tripolyphate and dye in the following ratio of components, May; Sodium or ammonium salt of alkylpolyox ethylene sulfate 7, 5-1 Polyethylene glycol ether monoethanolamides of synthetic fatty acids C, or polyoxy ethylethyl glycol ether of synthetic fatty alcohols in a specified weight ratio T, 5 Potassium tripolyphosphate 0,75 Carbamide 3, 65 Blow-dry. (sulfoethoxylates) of the general formula SpH2 "(. O) 50z X where n 6-16, m 1-4, X Na, NH4, for example, oxanol LTB. Traniums of a number of compositions in which detergency is determined are carried out. Determination of detergency is carried out according to the well-known method, according to which the ability is determined on enamel, since the nature is identical to the nature of the porcelain, face and glass surfaces. In tab. 1 shows the dependence of the effectiveness of the composition on the content of the scientific research institute components. From tab. 1, it follows that the highest detergency is achieved at the proposed ratio of components (formulations 5-7). Exclusion from the composition of non-ionic or anion-active surfactants (recipe 2,3), a decrease in the urea content (recipe / 12J leads to delamination. When removing potassium tripolyphosphate in the composition (recipe 4 precipitates. Increase in the content of surfactant or potassium tripolyphosphate (recipe 8.10 does not lead to an increase in detergency. Consequently, an increase in the concentration of data by the component is completely unjustified. A decrease in the content of surfactant or tripolyphosphate and potassium below the proposed limits (recipe 9,11 | reduces detergent ability. An increase in urea concentration (recipe 13 does not increase detergency. At the same time, it was found that maximum detergency is achieved when the ratio of anionic surfactant to non-ionic Isl (see Table 2). The dependence of detergency on the ratio of surfactant is shown in Table 2. From the data Table 2 shows that a violation of the ratio of surfactants (formulation 1.2) leads to a significant decrease in the cykny ability. The appearance of the agent is improved by the introduction of an acid yellow methanil dye. Production technology means soytoit in the usual blending of ingredients. The evaluation of the use qualities of the proposed composition is carried out according to known methods in comparison with the known means (Table 3. From the data of Table 3 it follows that the proposed composition is superior in detergency to the known means.
