Description

The invention relates to compositions of granules that increase the efficiency of synthetic detergents (CMC), with a whitening effect and are intended as an additive in CMC for hand and machine wash (in machines of any type) and soak all types of textile products, including non-color, and other household 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. So, for example, it is known that a washing detergent containing sodium alkylbenzenesulfonate, as nonionic surfactants, are ethoxylated alkyl phenols (neonols), sodium tripolyphosphate, peroxide bleach, Acremon carboxymethyl cellulose, sodium silicate, polydivonel, anti-smoking, opticone, 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 whiteness of the fabric after washing.

A synthetic detergent is known that contains sodium alkylbenzenesulfonate or ethoxylated monoalkylphenols based on propylene trimers, sodium tripolyphosphate, sodium metasilicate, soda ash, carboxymethyl cellulose, persolvate, perfume, sodium sulfate (RU 2177986 C2, 11.01.2002, 02.01. The disadvantage of this composition is the low washing ability and insufficient bleaching of the fabric after washing.

The closest technical solution is a synthetic detergent for washing and bleaching at low temperatures, containing in wt.%:

Sodium alkylbenzenesulfonate or a mixture thereof with sodium alkyl sulfonate or sodium salts of fatty acids - 8.0-13.0

Stearic acid polyoxyethylene glycol esters - 0.01-5.0

and / or ethoxylated fatty alcohols - 0.01-5.0

Oxyethylated alkyl phenols - 0-2.0

Sodium Tripolyphosphate - 21.0-24.0

Colored Granular Sodium Tripolyphosphate RHODIA-PHOS - 1.0-4.0

Sodium salt of a copolymer of acrylic and maleic acids - 1.0-2.0

Ethylene diamine tetraacetate sodium (trilon B) - 0.5

Sodium salt of nitrilotriacetic acid (trilon A) - 1.0

Sodium carboxymethyl cellulose - 0.5

Antisorption additive "DAR" - 0-0,2

Sodium silicate soluble - 4.0

Enzyme - 1.5

Optical Brightener - 0.25

Sodium Percarbonate - 12.0

Soda ash - 5.0-10.0

Tetraacetylethylenediamine (TAED) - 2.0-4.0

Sodium sulfate - the rest.

(RU 2177985 C1, 01/10/2002, С11D 1/83).

However, this synthetic 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-sedimentation of contaminants is possible on the fabrics, as well as insufficient whiteness of the fabric after washing.

The present invention is the creation of granular CMC, increasing the effectiveness of the detergent with a whitening effect.

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

The combination of the selected components in the selected ratio allows you to get a granular tool that improves the properties of CMC with a lower total number of components, which can significantly reduce the cost of detergent.

Sodium alkylbenzenesulfonate is used as the anionic surfactant.

Oxyethylated alkyl phenols based on propylene trimers (neonols) are used as a nonionic surfactant (nonionic surfactant), namely, monoalkyl phenols based on propylene trimmers with 9-12 ethoxylated groups, or ethoxylated higher fatty alcohols with 7 or 8 or 10 ethoxylated groups. Nonionic surfactants provide co-solubility of salts and low foaming, and also enhance the washing, dispersing and stabilizing effect.

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. Thus, when the agent of the present invention was introduced into the CMC in the laboratory wash of samples (250 washes), the formation of scale and no corrosion was detected.

As sodium silicate, you can 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 dispersant used is sodium polyacrylate or the sodium salt of a copolymer of maleic and acrylic acids or the sodium salt of a copolymer of acrylic, methacrylic and maleic acids.

As an antiresorption additive, carboxymethyl cellulose technical (CMC) is used.

As optical brighteners use Belfor KD-2C, and / or Tinopal CBS-X, and / or Rylux VPA-T, and / or Rilyufal, or other commercially available optical brighteners.

The tool of the present invention, in addition to conventional optical brighteners, contains a photo-bleaching agent providing a whitening effect in the presence of sunlight and artificial light. A particularly suitable photo-bleaching agent is the Tinolux IUD (trademark of Tsiba-Gaigi).

Everlase / Duramil enzyme preparations (5.3 / 14), or Everlase / Duramil / Cellluzim enzyme preparations (6/12 / 0.1), or Ox Blend 102 E, or Ox Blend 105 E, containing protease, are used as an enzyme. amylase and cellulase. The presence of enzymes in the detergent composition allows you to remove complex contaminants such as protein (grass, blood, egg, human sweat) and starch, freshens the fabric and prevents the formation of spools.

Sodium carbonate (soda ash) is used to soften water and regulate the pH of the medium.

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

The proposed powdered synthetic detergent will expand the range of high-quality granular CMC. In addition, the CMC with granules of the present invention has high consumer properties, technologically, economically, both in production and in application. The composition is based on available raw materials produced mainly by the domestic chemical industry.

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