Description

one

This invention relates to a technique for making detergent compositions.

There is a known method of shaking detergent compositions, consisting in TOMj that components are loaded into the Composite mixers in the following sequence:

surfactants (PAH alkyl sulfates, soap sulfate, synth, cola, and T; e), a mixture of liquid useful additives (carboxymethyl cellulose, sodium silicate, and bleach), water, finishing additives (sodium sulfate, sodium tripolyphosphate, trilon B, and etc.) 1., 5

The disadvantage of this stujoba disease is that during the preparation of the compositions of the moistened agents lumpiness and a sharp increase in their viscosity are observed.

This leads to the fact that a significant 20 of the products of the detergent composition in the form of lumps are deposited on the filter paXj kicks them, resulting in frequent stops for cleaning equipment and about.

irrevocable loss of products.

Getting a composition with a high content of lumpy. products due to the fact that bulk components (sodium tripolyphosphate, soda, etc.) contain aggregated particles, which, with the existing loading sequence of the recipe components, are wrapped with a mixture of tylezny additives (CMC and liquid glass) and do not dissolve in the future. The nonionic surfactants entering into the detergent formulations (syntanules and syntamides) are charged together with anionic surfactants in the first stage, while nonionic surfactants, compared with anionic surfactants, greatly accelerate the hydration of sodium tripolyphosphate, which contributes to a sharp increase in the viscosity of the composition. A composition with increased viscosity in front of the tub for drying requires diluting it with water to a moving consistency, which, in turn, affects the productivity of the drying units. The aim of the present invention is to have a lower body condition and exclude a lump of formation, TSH eK eShbYaTsHtHgt thu in the course of the student detergent using mixes of water and anionic active substance, liquid additives, water, red and white, liquid, water, and water, anxiously active substances, liquid additives an aqueous solution of anionic surfactant is mixed with water with the sequential addition of bulk, liquid additives and non-ionogenic surfactant. Sodium tripolyphosphate is supplied to the composition before loading a mixture of useful additives, which, therefore, eliminates the negative effect of CMC and water glass on the dissolution of the enlarged particles of sodium tripolyphosphate and other sigma components, but not ionogenic PA B (syntanols and symty amyds) in order to eliminate the possibility of reducing the viscosity of the composition, it is charged to the post of supplying all the components of the formulation immediately prior to the supply of the detergent compres- sion for drying. EXAMPLE 1 At the same raw materials, under the same mixing time, in laboratory conditions, detergent composition was prepared. The era of the automaton according to the proposed method and for comparison by a known method. The concentration of the composition on the solid part in both methods is kept constant (5O%). In tab. 1 shows the results of the experiments ..:, 1 a b l and a a 1

The result of the experiment:

The mass is homogeneous, mobile fluidity is maintained for 3-4 hours, and it is easily mixed. Example 2. At the enlarged test setup, a composition is prepared wet & 1. Anionic and non-ionic SH-39.2 g (alkyl sulfates, cpipt, 2 g, sulfonic acid - 8 soap acids (5-10 g syntanol 3.6 g)

The result of the experiment;

2 minutes after the supply of sodium sodium tripaliphosphate, the viscosity rises sharply, there is no flow, it is difficult to mix. The means of the Era-automaton according to the predicted and existing methods at the rate of obtaining 10 kg of powder on the same raw material, with a constant solid part (50%) and temperature conditions (BO – B3 C). All components were charged for 15 minutes. Subsequent mixing - 60 minutes The compositions are pressed, filtered and filtered through a sieve with a diameter

As can be seen from the table, when preparing the composition according to the proposed method, the amount of sediment on the sieve is insignificant, while with the existing loading of the components, the amount of sludge is more than 8%.

The loading of the components of the formulations of mox cich agents is carried out in sequences to the proposed method and for comparing 20 to a substantially stealth mode. At the same time, after filtering the composition of wet preparations prepared by the proposed method, the amount of sludge on the sieve was 0.61% for Lotos-Avtomat, for Neptune - 25 O, 88%. According to the existing method, respectively, 7.6 and 9.1%.

To compare the viscosity of the products, the conditional viscosity of the compositions is determined by the time of expiration (in seconds) on an OT-4 viscometer.

The composition, produced in the described manner, has a specific weight of 1.15 g / cm, and the conventional viscosity is 9 ° C. The composition obtained by the known 35 method has beats, weights, 1.17 g / cm, conditional viscosity - 750 s.
