Description

 The invention relates to sanitary-hygienic cleaning products intended for the effective removal of stable formations of rust, deposits of hardness salts from toilets, earthenware sinks and tiled surfaces.

Known sanitary-hygienic cleaner Sanaks, containing in wt.%:
sodium hypochloride - 4.0
caustic soda - 13.0
sodium metasilicate - 0.6
sodium tripolyphosphate - 0.1
sodium carboxymethyl cellulose - 0.02
water - up to 100
This cleaning agent is obtained by preliminary mixing the components and dissolving them with water at room temperature / Sanaks cleaning agent TU 6-015-1508-90 /.

 A disadvantage of the cleaning agent is that it does not have sufficient rust removal rates and the presence of active chlorine is irritating when using the airways.

 Closest to the claimed combination of essential features is a tool for cleaning appliances in toilets, containing 5-30 wt.% Hydrogen peroxide used as the main component, 1-15 wt.%, Inorganic or organic acid, mainly sulfamic, hydroxyacetic or acetic acids or hydrochloric acid and 6-56 wt.% water.

 This tool is obtained by mixing the above components / JP, 01240600 A, 1989 /.

 The disadvantage of this tool is that it has a low washing ability.

 The objective of the invention is the expansion of the range of cleaning products used, reducing its consumption by introducing a thickener, increasing rust removal efficiency.

где n = 1, 2;
m = 1-6.The essence of the invention lies in the fact that the proposed sanitary-hygienic cleaning agent contains: synthetic hydrochloric acid, a nonionic surfactant, VPK-402 polyelectrolyte, a corrosion inhibitor in the following ratio of components, wt.%:
synthetic hydrochloric acid - 10-15
nonionic surfactant - 1.0-1.5
polyelectrolyte VPK-402 - 3-5
corrosion inhibitor - 0.05-0.1
water - the rest
As a nonionic surfactant, syntanol or oxinol or neonol is used, and as a corrosion inhibitor, 1.2 disubstituted imidozoline of the general formula:

where n = 1, 2;
m = 1-6.

 The use of synthetic hydrochloric acid in the cleaning agent helps to remove stable rust formations and deposits of hardness salts due to its dissolution.

 The basis of the detergent part of the product is nonionic surfactants - syntanol, or oxanol, or neonol - contributing to foaming and enhancing the washing properties.

 The compatibility of surfactants (syntanol, oxanol, neonol) with acids, in particular synthetic hydrochloric acid, was studied. Surfactants - syntanol, oxanol, neonol, do not adversely affect the effect of rust removal, dissolution of salt deposits, and the carbon content of aqueous acid solutions.

 Corrosion inhibitor - 1,2 disubstituted imidozoline of the general formula (1) provides protection of the metal surface (pipelines) from acid corrosion.

 VPK-402 / TU 6-05-2009 / polyelectrolyte is a water-soluble polymer used as a thickener, i.e. gives the detergent a certain viscosity, which allows you to hold the agent on the surface to be cleaned and, due to viscosity, reduce the consumption of detergent.

 The above components provide the proposed cleaning agent with high cleaning and washing properties, helps to remove rust and grease.

The technological process for the production of cleaning products consists of the following stages:
- preparation of raw materials;
- dosing and mixing of raw materials;
- packing and packaging of finished products.

Mixing of the raw materials is carried out in any order by thorough mixing at 18-25 ^o C. All the components of the cleaning agent dissolve well in water.

 Packing is carried out by devices designed for packing liquid products.

 Example 1

In a container with a mixing device, the components are mixed at 18-25 ^o C until complete dissolution, in wt.%: Synthetic hydrochloric acid 10, surfactant - 1.0, polyelectrolyte VPK-402 - 3, 1.2 disubstituted imidazoline - 0.05, water is the rest. Determine the washing and cleaning ability. Cleaning ability,% - 85-90.

 For toilets: apply a cleaning agent to the contaminated surface, hold for 20 minutes, and brush.

 For sewer pipes: 200 g of the product is poured into the drain hole of the bathtub, sink, stand for 3-4 hours and rinse with plenty of water. In case of severe contamination, repeat the treatment, increasing the exposure time.

 Example 2

Analogously to example 1 is mixed in wt.%:
synthetic hydrochloric acid - 15
Surfactant - 1.5, polyelectrolyte VPK-402 - 5
corrosion inhibitor - 0.1
Cleaning ability,% - 85-90
The proposed sanitary and hygienic cleaning agent provides effective removal of stable rust formations, the deposition of hardness salts from toilets, fats from earthenware sinks, tiled surfaces, and also has a washing ability.

 The need for cleaning products in Russia is currently 7.7 thousand / t per year. In Bashkortostan, such cleaning products are not available.

 All the constituent components of the proposed cleaning agent are produced at Sterlitamaksky CJSC "Caustic", therefore the cost of 1 liter of cleaning agent will be 1,700 rubles together with a plastic bag.
