Description

The invention relates to household chemicals, in particular, compositions intended for washing dishes: porcelain, fancy, ceramic, crystal, glass and tableware.

The purpose of the invention is to increase the grain holding capacity and reduce the specific consumption of the composition in the process of washing.

The invention is illustrated as follows.

The apparatus from the mernik load the estimated mass of water with a temperature of 48 ° C or cold water is fed and

heated to the specified temperature using a heat transfer fluid supplied to the jacket of the apparatus. Then, a stirrer is turned on and carbamide, potassium tripolyphosphate, and Sinthanol ALM-10 heated to 48 ° C are charged.

Stirred for 10 minutes. After that, the alkyl sulfonate heated to 48 ° C and lauryl sulfate triethanolamine salt are loaded into the apparatus with stirring. The contents are stirred for 20 minutes, maintaining the temperature at 48 ° C. When complete dissolution of the components, which is determined by visual inspection of the sample from the reactor, is applied (

in the glass cylinder, start cooling the mixture. To do this, cold water is supplied to the shirt of the apparatus. After stirring for 20 minutes at 25 ° C, a perfume is charged. Next, the product is fed to the filtration of mechanical impurities contained in the raw materials. After filtration, the product is pumped into the collection, equipped with a stirrer. From the collection of the finished product is served on the packaging.

For any interchangeability of ani {en and non-ionic surfactants provided for by the composition and shown in the examples of Specific Performance, the loading sequence, temperature and mixing time do not change. Only the quantities of anionic surfactants vary depending on the content of the active base in them.

Table 1 shows the formulation of the composition at different ratios of the components.

The use of triethanolamine salts in the composition and the change in the concentrations and ratios of the other surfactants in the formulation allows an increase in the greening capacity and a reduction in the specific consumption of the agent in the wash process.

Grain holding capacity is characterized by the amount of soil (g) it holds in suspension. This indicator is estimated as follows: g of the contaminant is applied to a standard plate.

Ingredients: 20 g of beef tallow, 20 g of coconut oil, 29 g of sunflower oil, 30 g of cream margarine, 0.5 g of activated carbon and 0.5 g of acetylene black.

The soiled plates are then washed for 30 s in 10 l of the solution of the test agent at a concentration of 0.5 g / l.

The end point of the ability of the solution to depletion is the complete disappearance of the foam in the washing solution and the appearance of contamination on the control areas of the dish surface.

The amount of soil emulsified in 1 liter of the working solution of the medium is calculated by the formula

g 1,8 x n

ten

where 1.8 g is the amount of contaminant

on one plate; n - the number of washed plates; 10 - the volume of the washing bath.

A complex indicator characterizing consumer properties of dishwashing detergents is detergency, the determination of which is carried out according to a known method.

The data in Table 1 indicate that the carbamide in the composition acts as a hydrotropic additive, since a change in its concentration (composition 4.5) does not affect the properties of the composition. In Composition 4, a small precipitate is observed upon standing. This suggests that 2.5% is the minimum hydrotrope content at which the composition is homogeneous during storage.

The reduction in the crushing ability results in a reduction in the composition (6, 8, 10, 12) of the concentration of potassium tripolyphosphate, ALM-10 syntanol, triethanolamine salts of lauryl sulfate, alkyl sulfonate, and for the last two components this reduction is significant. These compositions also show a decrease in detergency. The increase in the concentrations of the listed components (compositions 7, 9, 11, 13) does not exceed the crushing capacity, the washing capacity is also not increased.

The optimum values for these indicators are compositions 1-3.

From the data of table 1 it follows that the specific consumption of the proposed composition is significantly lower than that of the known. This indicates that the composition is much more economical than the known one, since the washing ability is equal to the known one and is achieved at a concentration of components lower by 3-4.5 times. The proposed composition is more favorable from the ecological point of view, since raw materials, including surfactants, are 3-4.5 times less in water of reservoirs than if they do not use a known composition.

In table.1 shows the composition with one

combination of surface-active substances, since all other surfactant mixtures provide the same crushing capacity and low

specific consumption in the process of washing (Table 2).

In the proposed composition introduced the following raw materials.

As anionic surfactants: sulfonate (alkyl sulfonate), alkaline sulfate - emulsifier (volgonate) - a mixture of sodium salts of isomeric alkyl sulfonic acids with alkyl Cj (-C ig; liquid detergent Progress; sodium salts of secondary alkyl sulfates; triethanolamine salts of alkyl sulfates; oxyphos MEA - monoethanolamine salt of dialkyl polyethylene glycol phosphate ester; oxyphos AM - ammonium salt of dialkyl polyethylene glycol phosphate ester.

The composition uses the following nonionic surfactants: synthanol ALM-10 - a mixture of polyglycolic esters of synthetic fatty primary alcohols fr. (ethoxylate 10 moles of ethylene oxide); Sintamide-5 is a mixture of polyoxyethyleneglycol ethers monoethanol amides FFA; C10-Cfg (oxyethylated 5 mol of ethylene oxide) polyethylene glycol-115 is a polymer of ethylene oxide with ethylene glycol.

Potassium tripolyphosphate, a hydrotropic additive that increases the solubility of the components in the composition, urea, is used as a complexing agent.

To give a pleasant smell, various fragrances are introduced into the composition.
