Abstract

This invention relates to a technology for the production of household chemical goods, in particular, to the composition of a paste for cleaning household items and dishes with enamel, metal and ceramic surfaces. The goal is to increase the degreasing properties of the product while reducing its toxicity. To do this, use an agent containing, in wt.%: Soda ash 5,0-12,0,0; stearic acid ester 2.0-10.0; 3% peroxide solution: hydrogen 2.0-6.0; glass abrasive 50-70 and glycerin to 100. When using this agent, the degreasing properties increase from 65 to 85-90% while reducing its toxicity, i.e. low alkalinity (pH 8-8.5) and no odor. 1 tab. Ъ Ё

Description

The invention relates to the production of household products and VB can be used to produce cleaning pastes for cleaning household items and dishes with enamelled, metal and ceramic surfaces.

It is known a household cleaning product containing alkaline components, wt.%:

Sulfonol 3.0

Sodium tripolyphosphate 5.0

Soda Ash 12.0 /

Abrasive (pumice) 80.0

A disadvantage of the known means is the low cleaning ability, in view of the comparatively. low specific hardness of pumice. Content as

emulsifier sulfono limits the use of the composition, since the use of surface-active substances (surfactants) of this class for washing dishes is prohibited by health authorities. It is also known to use a powdered solid surface cleaner that contains crushed glass as an abrasive.

The disadvantage of this tool is the presence of dust inhaled air during its use.

The closest to the technical essence of the proposed is a paste-like means for cleaning a hard surface containing sulfamic. acid, ethylene glycol, sodium carboxymethylcellulose as a thickener, kieselguhr or perlite as an abrasive, and in

as a surfactant, monoethanolamides of synthetic fatty acids of the Syu-Cie fraction or sodium alkanesulfonates with the addition of urea and aluminum fluoride (production waste).

This paste-like agent is characterized by the complexity of the composition with a low content of abrasive and the use of toxic components (ethylene glycol and fluoride compounds), which contribute to the increased toxicity of this agent. In addition, the use of sodium carboxymethylcellulose (NA-SHZ) as a thickener increases the lubricity of the composition, while abrasive and degreasing properties are reduced, since the sodium-CMC gel shields the abrasive effect of the abrasive microparticles and surfactants on the treated surface.

The aim of the invention is to increase the degreasing properties of the agent while reducing its toxicity.

The goal is achieved by the fact that the detergent contains stearic acid ester as an emulsifier, glycerin as a solvent and thickener, and additionally contains soda ash and 3% hydrogen peroxide solution in the following ratio, wt%:

Soda ash 5,0-12,0 Ether of stearic acid 2,0-10,0 3% hydrogen peroxide solution 2,0-6,0 Glass abrasive 50,0-70,0

Glycerin up to 100

An analysis of the known technical solutions has shown that some components introduced into the composition are known, for example glass abrasive. In the proposed composition, a glass abrasive with a particle size of 1-10 microns, obtained after machining of optical parts, is used. Namely, optical production waste after the milling operation of optical parts. The use of glass abrasive in combination with chemicals possessing high degreasing and emulsifying properties, namely glycerol, stearic acid ester, soda ash and 3% hydrogen peroxide solution, allows to obtain a high degreasing effect of a cleaning agent with simultaneous a decrease in its toxicity, since glycerol and stearox-6 are safe substances, unlike ethylene glycol. In addition, glycerin contributes to the sedimentation stability of the composition, and in combination with hydrogen peroxide solution gives metallic surfaces shine. All components dissolve well in water, as a result of which they are easily removed from the surface. Composition is good

degreases the surface in cold water.: ..:.

For experimental verification of the cleaner, 7 mixtures of ingredients were prepared, 5 of which showed optimal

results (see table).

A cleaner is obtained by simply mixing the components at room temperature.

The scouring ability of the cleaning agent reflects the ability of the drug to chemically act on fatty contaminants — emulsify them. The essence of the method for determining the effectiveness of degreasing is to determine by the weight method the degree of removal of fatty contaminants by the test substance in comparison with the known one.

Consumer quality means determined by known methods. The sedative stability of the agent is evaluated according to the method of Guls, which consists in the fact that the tested composition is periodically stored in the temperature ranges from -10 to + 40 ° C.

Comparative assessments of the consumer qualities of a cleaner compared to the known are given in the table.

From the table it follows that the optimal ratio of components (examples 2-6)

provide the cleaner with high consumer properties. A reduction in the components below the minimum limit (Example 1) leads to a significant reduction in the degreasing ability of the cleaning agent.

An increase in components above the maximum limit (Example 7) does not give a perceptible increase in cleaning and

degreasing ability of the agent, but leads to an increase in pH above 10.5, which is unacceptable due to the appearance of a skin irritating effect.

Thus, the agent with high cleaning ability possesses high

degreasing ability; retains its texture without stratification for a long time; is odorless and has a low pH of -8-8.5, indicating low alkalinity,

The use of non-toxic components expands the area of use of the agent — used for all types of cookware and household items.

The use of these optical wastes as an abrasive allows to solve the problem of recycling.
