Description

The invention relates to compositions of powdered synthetic detergents (CMC) and is intended for both manual and machine washing and soaking of all types of textile products, including color, and other domestic needs.

The development trend of synthetic detergent formulations lies in the development of compositions combining high detergency with respect to various types of impurities with whitening ability at low temperatures. The beneficial effect of CMC on the fabric is also desirable, consisting in the absence of inlay, softening effect, increased brightness of dyed fabrics and the absence of spools, as well as reducing the harmful effects of the composition 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, it is known that a detergent for washing containing sodium alkylbenzenesulfonate, as nonionic surfactants, are ethoxylated alkyl phenols (neonols), sodium tripolyphosphate, peroxide bleach, Acremon carboxymethyl cellulose, sodium silicate, polyhydrous de-bleach, optical de-bleach, TA the product of the interaction of ethoxylated isononylphenol, triethanolamine and caustic, sodium sulfate and water (RU 2268293 C1, 01.20.2006, C11D 1/83).

The disadvantages of this synthetic detergent are insufficient washing ability, increased foaming and insufficient softness of the products after washing.

CMC is known for washing and bleaching at low temperatures, which contains anionic and nonionic surfactants, which are a mixture of sodium alkylbenzenesulfonate or a mixture of sodium alkyl sulfonate or sodium salts of fatty acids with polyoxyethylene glycol esters of stearic acid and / or ethoxylated fatty alcohols optionally with hydroxyethylated alkyl phenols, antisorbents - soluble sodium silicate and sodium carboxymethyl cellulose, complexing agent - sodium tripolyphosphate, colored granular sodium tripolyphosphate, sodium ethylenediaminetetraacetate (Trilon B) and sodium nitrilotriacetic acid (trilon A), sodium percarbonate, tetraacetylethylenediamine (TAED) and useful additives - sodium salt of a copolymer of acrylic acid, ferroenic acid, maleic acid, maleic acid optical brightener, perfume fragrance, filler - sodium sulfate and water (RU 2177985 C1, 01/10/2002, C11D 1/83).

However, the known detergent has a high oxygen bleach content and is unstable during long-term storage - the powder coalesces, the color of the agent itself changes due to the oxidation instability of the composition, it clumps, which leads to a decrease in its quality and detergency of the agent itself. In addition, re-deposition of contaminants and their insufficient softening is possible on the tissues.

The closest technical solution is a synthetic detergent containing in wt.%: Anionic surfactant 10.0-13.0; nonionic surfactant 2.0-3.0; sodium tripolyphosphate 20.0-30.0; urea peroxyhydrate 10.0-15.0; carboxymethyl cellulose (CMC) 0.3-0.4; polycarboxylate "Akremon" 0.1-0.2; liquid glass 3.0-4.0; soda ash 5.0-10.0; optical brightener 0.2-0.3; defoamer 0.5-1.0; tetraacetylethylenediamine (TAED) 1.0-2.0; 4-methyl-2,6-di-tert-butylphenol (4-methyl-2,6-DTBP) 0.005-0.20; perfume 0.1-0.2; enzymes 0.6-1.0; dye transfer inhibitor 0.05-0.10; water and sodium sulfate up to 100 (RU 2230102 C1, 06/10/2004, C11D 1/83).

The main disadvantage of this composition is the relatively low washing ability, especially at low temperatures, the applicability of the formulation only for washing cotton and linen fabrics. Other disadvantages are insufficient softness of the washed fabric and the use of an expensive antifoam.

The objective of the invention is to provide a powdered CMC with high consumer properties: high washing and bleaching ability at a low washing temperature, imparting additional softness to the washed fabric with reduced harmful effects on the metal parts of washing machines.

The technical result of the claimed invention is to increase the effectiveness of a detergent with a whitening effect, remove various types of contaminants, reduce the temperature of washing, as well as reduce the harmful effects on the metal parts of washing machines.

This is achieved by the fact that the claimed powdered synthetic detergent contains the following components, wt.%:

Anionic surfactant - Sodium Alkylbenzenesulfonate 10.0-16.0 Nonionic surfactant - ethoxylated fatty alcohols or ethoxylated alkyl phenol 2.0-5.0 Sodium Tripolyphosphate 15.0-25.0 Organophosphonate compound - 1-hydroxyethylidene sodium salt phosphonic acid or diethylene triaminopentaxis- (methylene phosphonate) sodium 0.2-0.6 Polycarboxylate 0.5-1.5 Carboxymethyl cellulose (CMC) 0.3-0.6 Modified Polyalkylene Glycol 0.2-0.6 Optical brightener 0.05-0.3 Soda ash 3.0-6.0 Liquid glass 3,5-6,0 Enzyme 0.4-0.7 Antifoam agent 0.05-1.5 Perfume 0.15-0.3 Sodium Sulfate and Water up to 100

In addition, the claimed CMC may additionally contain an intermediate CMC-turquoise granules, in an amount of 0.5-1.5 wt.%, Including the following components in wt%:

Sodium Alkylbenzenesulfonate 13.0-15.0 Sodium Tripolyphosphate 14.0-17.0 Liquid glass 3.0-6.0 Sodium carbonate 13.0-16.0 Tinolux Navy 1.0-1.5 Sodium Sulfate and Water up to 100.

Also, the claimed CMC may additionally contain sodium percarbonate in an amount of 7.5-19.0 wt.%, Tetraacetylethylenediamine (TAED) blue or tetraacetylethylenediamine (TAED) green in an amount of 1.0-2.5 wt.%, Sodium tripolyphosphate green in 1.5-2.5 wt.%, dye transfer inhibitor in an amount of 0.5-1.5 wt.%, aloe vera gel in an amount of 0.05-0.15 wt.%

Thus, the totality of the ingredients included in the composition of the product, taken in the above quantitative limits, provides a high detergent ability of the product in relation to various kinds of contaminants. At the same time, the product does not cake and maintains the stability of properties during storage.

As ethoxylated fatty alcohols (nonionic surfactants), Syntanol ALM-7 (ethoxylated fatty alcohols of fractions C ₁₂ -C ₁₄ (7 moles of ethylene oxide)) or Syntanol ALM-10 (ethoxylated fatty alcohols of fractions C ₁₂ -C ₁₄ (10 moles of ethylene oxide)) or Neodol 457 (ethoxylated fatty alcohols of fractions C ₁₄ -C ₁₅ (7 moles of ethylene oxide)) or Neonol AF 9-12 (is a technical mixture of polyethylene glycol ethers of ethoxylated monoalkylphenols based on propylene trimers), or Slovasol 257 ( oxyethylated fatty spa fractions mouths C ₁₂ -C ₁₅ (7 moles of ethylene oxide)), produced by both domestic and foreign industry.

A mixture of sodium alkylbenzenesulfonate and a surface-active substance (surfactant): slovasol, or syntanol, or neodol, or neonol, form the basis of the washing part of synthetic detergents.

Use of an acrylic acid-based polycarboxylate such as Sokolan PA 30 CL (sodium polyacrylate) or Sokolan CP5 (sodium salt of a copolymer based on maleic acid and acrylic acid), or Akusol 497 N (sodium salt of a copolymer based on maleic acid and acrylic acid), or Acremon AMK-10 helps prevent re-deposition of inorganic salts on the fabric, improve the appearance of products, disperse contaminants and increase the washing ability of the product.

The intermediate product CMC-turquoise granules gives the powdered CMC additional washing and whitening ability, allows you to get CMC with inclusions of turquoise color, which improves the presentation of CMC. Intermediate CMC contains sodium alkylbenzenesulfonate (sulfonol) as a surfactant. It also contains sodium tripolyphosphate and sodium carbonate (soda ash), which are introduced to increase the washing ability of the product and as water softening components. Soda ash also saponifies fatty contaminants, supplements and enhances the cleaning effect of surfactants. Sodium tripolyphosphate prevents the formation of scale on the metal parts of washing machines and softens the aqueous solution.

Liquid glass in the presence of a complexing agent enhances the ability to suspend polar pollutants and prevents their re-deposition on tissues, enhances the effect of soda ash to neutralize fatty contaminants. The turquoise dye Tinolux BMS (trading company Ciba-Geigy) allows you to achieve an increase in whiteness, as well as give the granules a turquoise color. Sodium sulfate is used in the product as a filler.

When testing various compositions of the intermediate CMC-turquoise granules revealed that the best properties have an intermediate having the following composition, wt.%:

Sodium Alkylbenzenesulfonate 13.0-15.0 Sodium Tripolyphosphate 14.0-17.0 Liquid glass 3.0-6.0 Sodium carbonate 13.0-16.0 Tinolux Navy 1.0-1.5 Sodium Sulfate and Water up to 100

Carboxymethyl cellulose (CMC) and a nonionic copolymer such as Sokalan HP-22 are used as antiresorptive additives.

Sodium tripolyphosphate is used as a complexing agent. The high content of complexing agents prevents the formation of scale on the metal parts of washing machines (especially heating elements) and significantly increases their service life. The use of colored granules of sodium tripolyphosphate makes the appearance of the powder more attractive.

The organophosphonate compound used in the present invention is the sodium salt of 1-hydroxyethylidene phosphonic acid (trade name Cublen K 8514 GR) or sodium diethylene triaminopentaxis (methylene phosphonate) (trade name Briquest 543-45). The organophosphonate compound is used in the detergent as an inhibitor of scale formation, which can significantly reduce the harmful effects on the metal parts of washing machines.

The presence of a dye transfer inhibitor in the formulation (Sokalan HP 56, as well as other commercially available dye transfer inhibitors) will improve the appearance of the product, prevent the ink from passing into the solution, and also its sedimentation on the fabric, and generally give the product a more pronounced updated look .

The inclusion of sodium percarbonate in the bleaching activator improves the quality of washing and provides a more complete removal of contaminants from fabrics, as well as to give a more pronounced whiteness to products made of white fabrics. In addition, tetraacetylethylenediamine (TAED) blue or tetraacetylethylenediamine (TAED) green will allow bleaching at lower temperatures (40-60 ° C).

As an enzyme, enzyme preparations Purafect Ox Blend 102 E or Purafect Ox Blend 105 E, or Everlase / Duramil / Cellulose containing a protease, amylase, cellulase are used. The presence of enzymes in the detergent makes it possible to remove complex contaminants such as protein and starch contaminants.

As optical brighteners, bleaches are used, for example, Belofor KD-2C, Rylux VPA-T, Tinopal CBS-X, Tinopal SWN _conc , Trophor A-25, Optivite 2 BH or other commercially available optical brighteners.

As the antifoam used silicone antifoam containing polydimethylsiloxane (DOW CORNING), as well as other commercially available defoamers.

Also, the composition of the composition may include aloe vera gel - a propylene glycol extract from aloe leaves, containing complex glycosides, vitamins E, C and group B, phytoncides, enzymes, mucous and resinous substances, a whole complex of trace elements, potassium, calcium, magnesium polysaccharides and other compounds. Aloe vera gel has softening and moisturizing properties, has a beneficial effect on the condition of the skin of the hands.

The inventive synthetic detergent obtained on existing technological equipment by spray drying the composition of the synthetic detergent.

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 produced mainly by the domestic chemical industry.

The examples in table 1 illustrate the invention without limiting its scope.
