Description

This invention relates to compositions of my own household compositions for washing articles made from various fabrics, and concerns solid, powdered, pasty: liquid detergents.

In the production of detergents, due to the high viscosity of the compositions, lumps, clogging of the nozzles of the drying towers are observed. This leads to an increase in energy consumption and with mixing, pumping and drying the composition, as well as to a decrease in drying performance. To eliminate these drawbacks, various viscosity reducing agents (hydrotropes,

toluenesulfonate, caproacta, polyacrylamide, urea, isopropyl alcohol, ethylene glycol are used as hydrotropic substances. et al. l.

However, these substances, being expensive and scarce products, worsen consumer properties of synthetic detergents (CMC). ,

The known detergent composition 2j containing a surfactant, for example, alhyl sulfate, alkyl aryl sulfonate, soap, a syringe, a soap, syntanol, syntamide-5, additives — sodium tripolyphosphate, sodium sulfate, water glass, carboxymethyl cellulose, water, and a hydrotropic additive — a neutralized gas sulfonated condensate condensate product. ) in the following ratio, wt.%: Surfactant 5-35

However, the composition has a high viscosity, insufficient detergency because rCK-Na does not possess detergent properties and is a ballast in the CMC.

The purpose of the invention is to reduce viscosity and improve detergency.

The goal is achieved by the fact that the detergent containing a surfactant, sodium tripolyphosphate, water glass, sodium sulfate, carboxymethyl cellulose, water, and hydrotropic additive, contains the sodium salt of dicarboxylic acid fraction Cd - C in the following ratio of components, wt. %:

Surfactant 5-35

Sodium tripolyphosphate 5-26 Liquid glass 0,2-4 Sodium sulfate 0,2-22 Carboxymethylcellulose 0, 2-1,3

Sodium salt of dicarboxylic acid fraction C4 - 0.1-2 0 Water up to 100

Alkyl benzene sulfonate, synanol, alkyl sulfates, syntamide-5, synthetic fatty acid soap, fractions can be used as a surfactant.

Prepare a detergent by adding

at 70 ° С hydrotropic additive to the previously prepared mixture

0 ingredients with subsequent mixing for 5 minutes.

In tab. 1 shows the proposed and well-known formulations of most funds. After preparation of the composition

5, viscosity and detergency are determined.

In tab. Figure 2 shows the results of the definitions (the magnitude of the viscosity and washing ability are given in% in this CMC-type Lotus composition, i.e. without introducing hydrotropes j.

As can be seen from the above data, dicarboxylic acids effectively reduce the viscosity of CMC compositions. Most- have greater efficiency

5 acids with p 6-10. These acids are waste products from the production of purified synthetic fatty acids.

Studies have shown the presence of a synergistic effect when the sodium tripolyphosphate and the sodium salt of dicarboxylic acid are combined in the medium: for example, the viscosity of a composition containing only 5% sodium tripolyphosphate is 120%

to the standard, if there is only di. carboxylic acid - 80%.

The use of dicarboxylic acids as hydrotrons in the CMC compaction allows to save the scarce raw materials (aromatic hydrocarbons) used for the production of rCK-Na, which will allow reducing the cost price of WASHING agents containing

hydrotropic substance. As a result of the decrease in viscosity, it became possible to increase the dry content in CMC compositions supplied to spraying and drying, which will lead to (significant savings: fuel.
