Description

 The invention relates to household chemicals, in particular to the production of synthetic detergents for washing products from linen, cotton and mixed fibers.

 Known composition (1) containing in wt.

Soap 29-34
Alkyl sulfates 0.001-1
Sodium Metasilicate 5-45
Water 5-10
Soda ash Else
The disadvantage of this product is that it cannot be used in water of various hardness, since insoluble calcium and magnesium salts form in hard water, which in turn settle on the material to be washed and make it rough and hard to touch.

 Closest to the invention for its intended purpose and the achieved result is a detergent (2) containing, by weight.

Sulfanol, alkyl sulfates, alkylamides 22 ± 2
Soda ash 15
Sodium Tripolyphosphate 30
Sodium Metasilicate 5
Carboxymethyl cellulose 1.5
Sodium Sulfate 24
Optical brightener 0.3
Fragrance 0.1.

 Lack of detergent, low washing ability, as well as harmful effects on the environment. The composition of the product in significant amounts includes condensed phosphates, which cause the growth of algae in waste water, leading to the death of organic life.

 The objective of the invention is to provide a detergent composition having a high washing ability without causing damage to the environment and reduce pollution of wastewater.

 This object is achieved in that the detergent for washing containing soda ash, sodium metasilicate, carboxymethyl cellulose, sodium sulfate, optical brightener and perfume additionally contains alkylbenzenesulfonates (or sodium alkanesulfonates) or monoalkyl ethers based on alkylene ethers of polyethylene glycol ethers propylene trimer in the following ratio of components, wt.

Alkylbenzenesulfonates or sodium alkanesulfonates 8.0 14.0
Primary fatty alcohol-based monoalkyl ethers of polyethylene glycol or propylene trimer-based ethoxylated alkyl phenols 2.0 66.0
Soda ash 38.0 52.0
Sodium metasilicate 9.0 11.0
Carboxymethyl cellulose 0.5 1.10
Fragrance 0.5 1.50
Sodium Sulfate Else up to 100
Moreover, the mass ratio of the components of the mixture of monoalkyl ethers of polyethylene glycol based on primary fatty alcohols or hydroxyethylated alkyl phenols based on trimer of propylene, soda ash, sodium metasilicate is 1 (8.66-24.66) (1.83-4.5)
The selected ratio of components allows you to achieve the desired result.

 The presence of a soda-silicate mixture with a surfactant provides a high washing ability.

 All surfactants included in the composition of the product are biodegradable substances; the absence of phosphates does not cause eutrophication of water in wastewaters.

 The proposed detergent is a white loose powder that can be prepared in industrial plants by dry mixing the calculated amount of the starting components on the existing equipment for the production of powdered detergents.

 Detergent tests were carried out at various components.

The washing ability of the compounds was determined according to the standard method (OST 6-15-1574-87) on artificially contaminated cotton chiffon art. 329 at a temperature of 50 ^o C and a detergent concentration of 5 g / l for 20 minutes

 The table shows examples of test formulations of the inventive detergent and known.

 The table shows that the inventive detergent (examples 2 to 4) with the proposed content of components and the mass ratio of monoalkyl ethers of polyethylene glycol based on primary fatty alcohols or ethoxylated alkyl phenols based on propylene trimer to soda ash and sodium metasilicate equal to 1 (8.66- 24.66) (1.83-4.5), provides 15% higher washing ability compared to the known tool.

 The change in the content of the components and the mass ratio between the components of the soda-silicate mixture with a surfactant above or below the claimed limits (examples 1 to 5) leads to a decrease in detergency to the level of a known agent.

 Example 6 characterizes the washing ability of the funds of the prototype.

The use of the proposed detergent provides the following technical and economic advantages:
1. High washing ability on heavily soiled fabrics.

 2. Compliance with environmental requirements.

 3. The preparation technology can be carried out on existing equipment for the production of powdered detergents and on domestic raw materials.
