Description

The invention relates to household chemicals, in particular to the production of liquid detergent suspensions for washing articles of their cotton, linen, mixed and synthetic fibers with the simultaneous removal of protein contaminants.

Suspension formulations are known. They include anionic, nonionic, cationic surfactants or mixtures thereof, active additives such as polyphosphates, zeolites, calcium and magnesium salts, alkali metal silicates.

The disadvantages of these formulations are the insufficiently high stability of the suspensions during storage and the washing effect.

The closest in technical essence is a liquid detergent containing may%:

Alkylsulfonate Sodium 12-17

Potassium soap of synthetic fatty acids fraction C17-C221-7

Potassium soap of oleic acid 0.5-5.0 Polyethylene glycol ethers of synthetic fatty alcohols of the fraction С-Сш 5-7 Potassium tripolyphosphate 5-10 Potassium adipate 1-4 Calcium chloride or magnesium chloride 0.4-1.0 Ethylene glycol 8-12 Proteolytic enzyme 1- 3 Fragrance 0.1-0.3 Bleach 0.1-0.3 Water up to 100 The main disadvantages of the known agent are the insufficient storage stability of the suspension and the washing effect.

The aim of the invention is to increase the stability of the state of aggregation and detergent action of the agent.

The goal is achieved in that the detergent containing the polyethylene glycol ether of synthetic fatty alcohols fraction. potassium soap of oleic acid, potassium soap of synthetic fatty acids of the C17-C22 fraction, ethylene glycol, potassium adipate, proteolytic enzyme, perfume, bleach and water, according to the invention, additionally contains polyethylene glycol ether of p-nonylphenol with 10.12 mol of oxy- si ethylene, sodium tripolyphosphate. magnesium sulfate or acetic acid and sodium tetraborate in the following ratio of components, wt.%: Polyethylene glycol ether of n-nonylphenol with 10.12 mol of oxide

An alkaline protease (TU 64-13-19-19-89), alkalase, is used as an enzyme in the composition of the product. esperase, savinase, maxatase. maksakal and others in the form of a powder, granules or a stabilized enzyme-containing aqueous composition.

The invention is confirmed by examples of specific performance (see table. 1).

Each composition is prepared separately, for which 2/3 of the amount of water, a solution of potassium hydroxide, are loaded into the reactor with the stirrer running and the heating turned on. At a temperature of 70-80 ° C, molten synthetic fatty acids and oleic acid are slowly fed. Saponification is carried out for 40-60 minutes. Then they turn off the heating, turn on the cooling and

components are set in the following sequence:

sodium tripolyphosphate;

a solution of potassium adipate;

- polyethylene glycol esters of nonylphenol;

-polyethylene glycol esters of synthetic fatty alcohols. with optical brighteners;

- at a temperature of 40-45 ° C, a stabilized enzyme;

ethylene glycol;

-fragrance.

The tool is mixed for 10-15 minutes and

through the homogenizer served in the collection of finished products, and then for packaging.

Enzyme stabilization is carried out in an apparatus equipped with a stirrer with a speed of 40-60 rpm and heating. Download 3 times the amount of water relative to the enzyme. At a temperature of 40-45 ° C, the calculated amount of magnesium sulfate or acetic acid is introduced, after dissolving it, tetraborate is charged

on three . The temperature is reduced to 33-37 ° C and the calculated amount of the enzyme preparation is loaded. Enzyme stabilization is carried out with periodic stirring for 1 hour.

The obtained compositions of Examples 1-11 were tested for: stability of the suspension structure, washing action and removal efficiency of protein contaminants over a long shelf life, i.e.

after 6 and 12 months

The stability of the structure was determined by centrifuging the samples under reproducible conditions according to GOST 22567-3-77.

The washing effect was determined on standardly soiled cotton samples when washed in a launderometer at a concentration of 5 g / l. temperature 50 ° С, bath module 1:50. The efficiency of removing protein contaminants was determined on an EMPA-116 fabric (Switzerland) with special protein contamination when washed in a launcher at a concentration of 5 g / l, at a temperature of 50 ° C.

Proteolytic activity was determined by the modified Anson method (FOLP method). The test results of the samples are given in table. 2.

As can be seen from the table. 2, the introduction of sodium tripolyphosphate in the proposed composition in combination with magnesium sulfate or acetic acid and sodium tetraborate improves the aggregative stability of the suspension, ensures stability during storage, and increases the detergent action.

The use of magnesium sulfate or acetic acid, sodium tetraborate and tripolyphosphate sodium in the ratio of 1: 1: 10 to 1: 3: 10 in the proposed composition increases the washing effect, the efficiency of removing protein contaminants and the stability of enzymes during storage by 50-60% .

The above method of preparation of the product provides good fluidity of the product, preventing coagulation over a long shelf life.

The detergent according to the invention is technologically advanced and can be produced using existing technological equipment.

The production of the product is environmentally friendly, non-waste.
