Description

Technical field

The invention relates to compositions of powdered synthetic detergents (CMC) and can be used for both hand and machine wash, as well as for soaking all types of textiles, including non-color, especially for fabrics with protein, starch and blood stains , and other household needs.

State of the art

The development trend of synthetic detergent formulations is to develop compositions that combine high detergency with respect to various types of contaminants, and a composition with whitening ability at low temperature. The beneficial effect of the composition on the fabric is also desirable, which consists in the absence of inlay, softening effect, increased brightness of dyed fabrics and the absence of spools, as well as reducing the harmful effects on the metal parts of washing machines (corrosion and scale formation).

A number of compositions are known that to one degree or another meet these requirements. For example, a washing detergent is known that contains anionic and nonionic surfactants, sodium tripolyphosphate, crystalline porous sodium polysilicates, sodium liquid glass, carboxymethyl cellulose, chemical bleach, stabilizer, soda ash, optical bleach, perfume, sodium sulfate (SU 1225851 A, 04/23/1986, C11D 3/08).

The disadvantages of this tool are the high content of silicates in the detergent, which leads to poor solubility of the agent in water, low washing and bleaching abilities. In addition, the lack of production of layered silicates by domestic industry and their high cost abroad make it difficult to produce detergents available to consumers.

CMC is known for washing and bleaching at low temperatures, which contains anionic and nonionic surfactants, which are used as a mixture of sodium alkylbenzenesulfonate or its mixture with sodium alkyl sulfonate or sodium salts of fatty acids with polyoxyethylene glycol esters of stearic acid and / or hydroxyethylated fatty alcohols optionally with hydroxyethylated alkyl phenols, antisorbents - soluble sodium silicate and sodium carboxymethyl cellulose, complexing agent - sodium tripolyphosphate, stained granular sodium tripolyphosphate RHODIA-PHOS, sodium ethylenediaminetetraacetate (Trilon B) and sodium nitrilotriacetic acid (trilon A), sodium percarbonate, tetraacetylethylenediamine (TAED) and useful additives - sodium and sodium copolymer enzyme copolymer calcined, optical brightener, perfume fragrance, filler - sodium sulfate and water (RU 2177985 C1, 10.01.2002, С11D 1/83).

But the known detergent has a high oxygen bleach content and is unstable during long-term storage - the powder is caking, the color of the agent itself changes due to the oxidation instability of the composition, it clumps, which generally reduces the quality and washing ability of the detergent itself. In addition, re-sedimentation of contaminants is possible on the tissues.

The closest technical solution to the present invention is a synthetic detergent for washing clothes containing in wt.%: 10-13 anionic surface-active substances (surfactants), 2.0-3.0 nonionic surfactants - sodium salt of carboxymethylated isononylphenol ethoxylate - " sinterol ", 20.0-30.0 sodium tripolyphosphate or 20.0-25.0 sodium tripolyphosphate and 2.0-3.0 sodium citrate, 10.0-15.0 urea peroxyhydrate, 0.3-0.4 carboxymethyl cellulose (CMC), 0.1-0.2 Acremon polycarboxylate, 3.0-4.0 glass of sodium liquid, 5.0-10.0 soda ash, 0.2-0.3 optical bleach, 1.0-2.0 tetraacetylethylenediamine (TAED), 0.005-0.20 4-methyl-2,6-di-tert-butylphenol, 0.05-0.10 dye transfer inhibitor - ChromaBond pyridine-based polymer P-400Z, 0.6-1.0 enzymes, 0.5-1.0 antifoam, 0.1-0.2 perfumes, filler - sodium sulfate and water up to 100 (RU 2230102 C1, 06/10/2004, С11D 1 / 83).

The main disadvantages of the known detergent are the high content of expensive oxygen bleach in it, which affects its cost and adversely affects fabrics, the insufficient washing ability of the product, the inability to use it for all types of laundry, and the undesirable effect on the metal elements of washing machines. In addition, the known tool contains many components, which makes it quite expensive.

Disclosure of invention

The basis of the present invention is the task of developing and creating a synthetic detergent with improved performance.

As a result of solving this problem, it is possible to obtain technical results, consisting in the fact that by using the selected ingredients in the declared amounts, a powdered synthetic detergent is created that has both improved consumer properties - high washing and bleaching abilities with a low content of oxygen bleach, which gently acts on fabrics and protecting the expensive elements of the washing machine from corrosion and scale formation, and cheaper, which is economically Lee advantageous to the consumer.

These technical results are achieved in that the powdered synthetic detergent contains the following components in wt.%:

Anionic Surfactant 8.0-13.0 (Surfactant) Nonionic Surfactant - Oxyethylated 2.0-5.0 fatty alcohols Sodium Tripolyphosphate 20.0-30.0 Sodium Ethylenediaminetetraacetate (Trilon B) 0.5-1.0 Acrylic based polycarboxylate 0.2-0.5 Acids Carboxymethyl cellulose (CMC) (in terms of 0.4-0.6 per 100 wt.% the proportion of the main substance) Sodium silicate (in terms of SiO ₂ ) 4.0-6.0 Sodium percarbonate or sodium peroxoborate 2.0-6.0 (in terms of active oxygen) Tetraacetylethylenediamine (TAED) 2.0-4.0 Enzymes 0.4-1.0 Soda ash 5.0-15.0 Optical brightener 0.05-0.4 Perfume 0.1-0.3 Sodium Sulfate and Water up to 100

The combination of the selected components in the selected ratio allows you to get CMC with improved properties with a smaller total number of components, which can significantly reduce the cost of detergent.

High washing ability is achieved by the optimal detergent formula. It is known that increasing the total content of surfactants to 18 wt.% Leads to an increase in washing ability. In the future, the dependence "washing ability - surfactant content" reaches saturation and an increase in the mass fraction of surfactants is impractical both from a technical and economic point of view.

As anionic surfactants, soaps of fatty acids or fatty acids of animal edible fat, fatty acid of industrial salomas, fatty acid of industrial distilled acids and sodium hydroxide for saponification of fatty acids (in terms of 100 wt% of the main substance) can be used.

As nonionic surfactants, ethoxylated fatty alcohols can be used, for example, Sintanol ACSE-12 (polyoxyethylene glycol esters of synthetic primary higher fatty alcohols of the C ₁₆ -C ₂₀ fraction), Sintanol ALM10 (a mixture of polyoxyethylene ethers of fatty alcohols of the C12-C14 fraction), Sintanol ALM-7 (ethoxylated fatty alcohol fraction C12-C14) or Slovasol 458 (ethoxylated fatty alcohol fraction C12-C15 with 8 moles of ethylene oxide).

Sodium tripolyphosphate and disodium or tetrasodium salts of ethylenediaminetetraacetic acid (Trilon B) are used as complexing agents. The combination of several complexing agents allows you to bind hardness salts and prevents the formation of scale on the metal parts of washing machines (especially heating elements) and significantly increases their service life.

The use of polycarboxylate, such as Sokolan PA 30 CL, Acusol 497 N, Akremon B-1, Akremon SP-5, Akremon AMK-10 or CAM polymer, helps prevent re-deposition of contaminants on the fabric, improve the appearance of products, prevent the formation of spools, increase surfactant activity and increase the washing ability of the product.

As sodium silicate use liquid sodium glass or soluble sodium silicate, which acts as an activator of the washing action and at the same time provides an alkaline environment, and also inhibits the corrosive effect of the detergent.

The oxygen-containing bleaching system sodium percarbonate or sodium peroxoborate - tetraacetylethylenediamine (TAED) allows bleaching of linen at low temperatures (40-60) ° С and in combination with other CMC components allows to achieve a bleaching ability of 120-130% according to GOST 22567.11-82. In addition, the low content of aggressive chemical bleach protects fabrics from destruction, reduces the harmful effects of contact with detergent and reduces the cost of the detergent itself.

As enzymes, enzyme preparations Everlase / Duramil (5.3 / 14) or Everlase / Lipolase or Purafect Blend Ox P 2000, Purafect OX Blend 30E or Purafect Ox Blend 105 E containing a protease, amylase, lipolase are used. The presence of enzymes in the detergent composition allows you to remove complex contaminants such as protein, starch and grease stains.

As you know, white fabrics and products made of them age in the process of wearing and washing, i.e. lose their original whiteness and freshness, so there is a need to update their appearance and whitening. To enhance the whitening effect, optical whitening agents are introduced into the CMC. Optical brighteners that can be used in this invention can be systematized in the following subgroups: derivatives of stilbene, coumarin, FOO of the distyryl biphenyl type and other combined agents. These bleaches include the series Belofor KD, Relyuks, Tinopal.

The synthetic detergent of the present invention is obtained on existing technological equipment by spray drying.

The powdered synthetic detergent of the present invention is characterized by high consumer properties, technologically, economically, both in production and in use. The composition is based on available raw materials.
