The invention relates to the technical detergents, in particular to means for cleaning glasses, mainly the front, of the car.
Known compositions for cleaning automotive glass (A.S. SU # 1097663, 1984; RU patent No. 2092532, 1997; patent RU No. 2167192, 1999), which have a cleansing and washing properties, due to the fact that their composition includes a surfactant (hereinafter - surfactant), and odorants, co-solvents, alcohols, which dissolve fat and other impurities.
Known means for cleaning automotive glass represent solutions glass cleaning liquid containing substances which have a negative impact on the rubber side of the washer system and paint of your car. In addition, when used in the environment are chemically aggressive and toxic substances.
The disadvantages of this tool can also be attributed a negative impact on the appearance of the paintwork of the car, as well as the fact that this tool is a solution, and this leads to the bulkiness of its packaging.
Modern detergents are complex, optimized by many parameters formulations. In addition to the surfactants they include: protective and conditioning additives, gidropony and co-solvents, bactericides and anti-oxidants, pigments, chelating agents, n is organic salts and perfume, viscosity regulators and antistatics.
Known preformed tool for cleaning glasses (U.S. patent No. 6057281, 02.05.200)containing anionic surfactants.
In addition, it is known tool for cleaning glass surfaces in the form of tablets (publication of the international application WO 0068354 A1, 16.11.2000)containing surface-active substance and emit gas system, which may include a carbonate or sodium bicarbonate and citric acid. The total amount of the carbonate of an alkali metal and acid may be 35-75%, surfactants can be nonionic or anionic.
It should be noted that the known tablets means have different characteristic functions, namely are the means for cleaning glass surfaces.
It is known tool to clean the front glass of the vehicle (patent KR 9004519 published 28.06.1990), as adopted by the applicant as the closest analogue for the appointment and contains one surfactant is sodium dodecyl sulfate (0,005-0,02%), and methanol (25-30%), water and a small amount of blue dye.
Despite the variety of existing detergents, it is fundamentally important and necessary as a glass cleaning liquid to use only those cleaning products that are designed specifically for the washer system of the vehicle.
Also important is about to use the exact dosage of the active components. As the active component of detergents the most widespread of anion active surfactants. Optimal surface-active properties have dodecyl sulphate and remotemachine dodecylbenzensulfonate.
The use of mixtures of both homologous and heterogeneous surfactant is common practice in the compounding of detergents, however, it has a greater impact on cost than on the quality of the tools. Therefore, it is advisable to create a recipe tools to include in the composition of the product only one surface-active substance.
Thus, to date from the prior art unknown means for cleaning car Windows, available in tablet form and has proposed a quantitative component.
The present invention solves the problem of creating tools for window cleaning it is a vehicle that represents a homogeneous powdery mixture of components in a certain proportion, is compressed in a tablet, and has not only a high cleansing and washing properties, but which is optimally matched to consumer quality and convenience of its operation in the washer system of the vehicle.
The technical result of the invention is that when used with the estva for cleaning car Windows in the stated proportions of the components it is not chemically aggressive to finish and rubber parts washer, as well as toxic to the environment.
The technical result is achieved in that the means for cleaning car Windows contains sodium lauryl sulfate, and sodium bicarbonate and citric acid anhydrous and is homogeneous powder mixture is compressed in a tablet, in the following ratio, wt.%:
|sodium lauryl sulfate||20,0|
|citric acid anhydrous||30,0|
The essential feature characterizing this invention, is a well-balanced selection of components constituting the composition in the form of a homogeneous mixture of powdered components (sodium lauryl, sodium bicarbonate and citric acid anhydrous), compressed into a tablet, enabling only in these quantitative values to obtain a technical result.
It is a balanced composition of the components constituting the composition in the form of a homogeneous mixture of powdered components, reduces the content of surfactant (sodium lauryl) to the minimum value and to maintain consumer quality tools, zaklyuchayushchiesya cleaning and detergency.
The tool is selected in such a way that when a small number (relative to the known means of similar purpose) components maximizes the effect of removing impurities of different origin.
It was found that citric acid and sodium bicarbonate is included in the composition, are involved in the formation of citrate, which detergency has a number of advantages over polyphosphates, in particular tripolyphosphate, the use of which is limited due to the tightening of rules on the protection of the environment.
It should be noted that citric acid and sodium bicarbonate are not only source products to obtain sodium citrate, and leavening agents, which composition tableting mass provide them with a fast mechanical destruction in a liquid medium (water)that is necessary for the release and distribution of the active substance.
Thus, citric acid and sodium bicarbonate ensure the destruction of the tablets in liquid medium in the gas.
Sodium bicarbonate is included in the composition, not only participates in the formation of citrate, but soterias in the composition in excess, contributes to the removal of fatty stains from the surface of the glass of the car.
Used by dissolving tablet and tap water usually contains a lot of salts of calcium and magnesium, which determine the hardness of water. In such water, the activity of the surfactants is significantly reduced, as are formed of poorly soluble salts.
Citric acid helps to reduce the hardness of water as formed with cations of calcium and magnesium contained in the water, the stable complex compounds and does not allow you to interact with members of surfactant composition, which is a sodium lauryl sulfate, which has expressed washing capacity.
Changes in qualitative composition of the product will lead to undesirable consequences, such as poor solubility tools in cold water; education in hard water insoluble salts, particles which will clog the washer system of the vehicle; changing the strength of the glass and its fading with the formation of streaks.
The change of the quantitative composition of the components of the means for cleaning car Windows will lead to undesirable changes in consumer qualities.
So, change the content of citric acid and sodium bicarbonate (baking soda)included in the means, causes a change in the pH of the solution, which will lead to undesirable effects on the car paint; in particular, the decrease in the content of citric acid and sodium bicarbonate (baking soda) can cause dissolution of funds representing with the second mixture of powdered components, compressed into a tablet.
The decrease in the content of sodium lauryl and sodium bicarbonate will lead to a sharp drop in the cleaning ability of the solution, and the increase in the content of sodium lauryl and sodium bicarbonate will increase the foaming in the process of dissolution, which adversely affect the operation of the washer system of the vehicle, because the solution will spill out of the washer tank.
The invention is illustrated by the following examples.
Example 1. Cooking cleaning car Windows.
The process of manufacture of tools, which is a mixture of powdered substances, compressed into a tablet, consists of the following steps.
Initially weighed components means that we take the following quantitative proportions:
|Sodium dodecyl sulfate (valid|
|Sodium bicarbonate (GOST 2156-76)||5,0|
|Citric acid anhydrous (GOST 3652-69)||3,0|
Mixing of the components, in specific proportions, carried out in a mixer inertial falling to a fully homogenous mass within 20-30 minutes. Need about the mark, what components should be thoroughly mixed to distribute them in the total mass, with the purpose of obtaining a homogeneous pellet mixture.
Production method based on the pressing mixed in the proportions of the components. Pressing (actually tableting) is the process of education "tablets" of the powdered material under the action of pressure. Tableting is carried out on special presses. Pressing hold on the press for tabletting (TA-02) GOST 7434-2002. The working cycle of dosing material, the formation of tablets by pressing, pulling and dropping, is carried out automatically.
The described method are compressed into a tablet powdery white product.
Example 2. Determining the cleaning power tools

|Qualitative reaction for the presence of anion active surfactants||The emergence of Muti|
Testing has shown that the quantitative composition of the components is optimal with a relatively small number of its components, achieves maximum effect of removing impurities of different origin.
Cleansing (my the traveler the ability of a solution can be 97% and depends on the volume of water used for solution preparation. The consumer may, at its discretion, to adjust the concentration of surfactant in solution. Because the pill contains a fixed number of surfactants, every time in the preparation of "working" solution is obtained (ceteris paribus) solution of a given concentration.
The optimal ratio for the preparation of "working" solution is 1 tablet per 5 l of water. In cases of substantial amounts of water 1 tablet can be reduced to 2.5 liters, however, further reduce the amount of water is impractical due to the slow process of dissolution of the tablet and increase the foaming solution because of the formation of concentrated solution.
In use, the tool does not have a negative effect on the strength and condition of the car Windows, on the rubber side of the washer system; not contaminate the washer system of the vehicle due to its good solubility in water; does not cause corrosion of painted metal surface of the car.
In addition, the interaction means with the ambient air and wastewater toxic compounds are not formed, as contained in the tool components on propensity to bearspaw classified as soft deleted on the structures of bioremediation at 98%.
