Description

The invention relates to liquid sanitary-hygienic cleaning compositions for household use, namely to sanitary-hygienic cleaning products for interior items: windows and window frames, floor and wall ceramic tiles, sanitary ware, washable wallpapers, plastic or metal panels of suspended ceilings, parquet, Carpets and other interior details, and can also be used to clean the skin of the hands.

One of the urgent modern sanitary and hygienic problems is the removal of tobacco tar and tar from the surfaces of various household and household materials, as well as other components of tobacco smoke, which are a source of carcinogenic pollution. Tobacco smoke is a concentrated aerosol: a mixture of gases and highly concentrated particles suspended in the air, which condense and form a resin that settles on the surface of objects in the zone of exposure to tobacco smoke. The particulate smoke phase contains mainly nicotine, water, and tar tar.

A known solution according to patent DE202006005910. A water content of at least 55% in the detergent does not allow this agent to dissolve the tarry substances of tobacco smoke.

In the well-known solution for patent JP2002241790 also a large water content (not less than 75%) makes this tool useless for solving its goals.

Patent RU2367528 describes the use of an organic solvent that is a halogen derivative. Its use is unacceptable due to toxicity.

Also, the following products were used to remove tobacco resins and resins of similar origin based on aqueous solutions of alkali or organic solvents that are not miscible with water.

Known detergent for cleaning smoke chambers and chimney pipes from plaque - soot smoke, containing sodium carbonate, trisodium phosphate and an ionic surfactant, including additional sodium hydroxide and sodium metasilicate (patent RU2010844, MKI: C11D 1/66, C11D 1 / 66, C11D 3:04, C11D 3:06, C11D 3:08, C11D 3:10, publ. 04/15/1994).

The disadvantage is that this tool is a very aggressive solution that can destructively affect the structure of fabric materials, leather, including artificial, paint and varnish coatings, metal surfaces susceptible to corrosion, and also has environmental and chemical safety restrictions.

Known cosmetic means for removing tobacco resins based on terpenes and terpenoids and compositions for oral hygiene based on this tool, including toothpastes and other products. Turpentine, a liquid mixture of terpenes and terpenoids, dissolves some resins, fats and oils and is widely used to dissolve varnishes and paints. The main share of tobacco tar is also polycyclic hydrocarbons. Therefore, it was suggested that turpentine should dissolve the tobacco resin (patent RU2414210, MKI A61K 8/97, A61K 8/18, A61Q 11/02, publ. 28.12.2009).

The disadvantage is that turpentine, which is part of this product, does not mix with water and cannot be effectively removed from the treated fleecy surface with water, and can also damage plastic and paint coatings. As a result, the tobacco resin dissolved in it will be retained along with turpentine residues in the fleecy surface.

The closest analogue is the patent KR20110083810, which describes the composition of the detergent using ethanol (85-92.5 wt.%), Propylene glycol (5-10 wt.%). The tool developed in this patent is intended for its removal only from smooth surfaces (skin). In this regard, it does not contain a nonionic surfactant, which is necessary for subsequent washing of the resulting solution with water. Attempts to wash off a solution that does not contain surfactants lead to the fact that the dissolved oil is released in the form of a second liquid phase, sticks to the treated surface and will not be removed.

The technical result of the invention is a cleaning agent that is safe for domestic use and effective for removing tobacco tar and tar tar with an increased dissolution rate of these components of tobacco smoke and at the same time with the possibility of their maximum removal from the surface being cleaned, especially from the surface of fabric materials, leather, including including artificial.

The specified technical result is achieved due to the fact that a sanitary-hygienic cleaning agent containing a volatile organic solvent isopropanol or ethanol, a non-volatile organic solvent propylene glycol, characterized in that it contains a nonionic surfactant and a flavoring agent, and all of these components are presented in the following ratio, wt.%: propylene glycol - 5-15, nonionic surfactant - 0.5-2.0, flavoring - 0.1-0.5, isopropanol or ethanol - the rest.

The technical result is achieved due to the high dissolution rate of the tobacco tar (less than 1 min), due to its full miscibility with water, which is used to remove the dissolved tar from fleecy and other hard-to-reach surfaces, and also by keeping the tobacco tar in solution even after evaporation of the volatile solvent .

The proposed qualitative and quantitative composition of the claimed funds is necessary and sufficient to achieve the specified result.

The product contains a balanced composition of volatile and non-volatile solvents: isopropanol or ethanol and propylene glycol, in connection with which a high dissolution rate of the tobacco resin is maintained, and the tobacco resin remains in solution after evaporation of the volatile solvent.

Optimally selected type and content of surfactants allows you to get a stable, homogeneous tool, which without reducing the dissolving properties allows you to quickly and efficiently remove the resulting solution of tobacco resin with water.

Thus, the selected composition of the cleaning agent allows you to quickly and effectively clean smooth and fleecy surfaces of various materials, such as plastic, ceramics, metal, wood, glass, fabrics, leather, including artificial, dissolving the tobacco resin, keeping it dissolved even after drying out and dissolving in a stream of water with the formation of foam, which increases the cleaning efficiency.

Traditionally, volatile organic solvents negatively affect the skin of the hands, however, due to the content of propylene glycol, which, like glycerin, is able to form a moisture-retaining film on the surface of the skin, a reduction in the “drying” effect is achieved. Thus, the use of the above additives provides protection for the skin of the hands, which allows the use of the claimed product without fear for people with sensitive skin, and also use this tool to clean the skin of the hands from tobacco tar.

Another essential component is the flavor (perfume), which provides masking odors of volatile organic solvents (isopropanol or ethanol). As a flavoring agent, the product contains, for example, a perfume compositional fragrance with the aroma of watermelon, grapefruit, orange or apricot. Aromatic additives give the product a pleasant smell.

It retains its qualities during storage for a long time without changing color, separation of liquid phases or precipitation of any insoluble substances.

Example 1. Tobacco tar liquid placed in a vial.

The liquid is selected in the composition, wt.%:

propylene glycol fifteen nonionic surfactant 2.0 flavor 0.5 isopropanol or ethanol the rest is up to 100%

This product has a high viscosity due to the high content of propylene glycol, and its use in the form of a spray is allowed, but less effective. Applying such a tool on fleecy surfaces takes a lot of time, so the treated surfaces must be reliably protected from drying out. A further increase in the content of propylene glycol leads to a decrease in the dissolution rate of tobacco resins, and such compositions are not suitable for solving the problem. From the fleecy and other hard-to-reach surfaces, the resulting tobacco resin solution can be removed only with a large excess of water, and for this the content of nonionic surfactant should be as permissible as possible. An increase in the surfactant content above the specified norm leads to an unjustifiably large volume of water necessary for the complete removal of the agent. The increased flavor content is due to the need to drown out the unpleasant odor of isopropanol, which can partially be retained on fleecy surfaces. A further increase in the content of flavorings leads to the appearance of an unpleasant hue in their smell.

Example 2. Liquid for the removal of tobacco resins. Use in the form of a spray (or aerosol with the addition of a propellant 1-10%).

The liquid is selected in the composition, wt.%:

propylene glycol 10 nonionic surfactant 1,0 flavor 0.2 isopropanol or ethanol the rest is up to 100%

This product has a satisfactory viscosity due to the average content of propylene glycol, and its use in the form of a spray or aerosol is optimal. The application of such a tool on fleecy surfaces also takes a lot of time, so the treated surfaces must be reliably protected from drying out. A further reduction in propylene glycol is therefore undesirable. The amount of applied agent in the case of using a spray or aerosol is lower than when using a bottle, so the amount of water required to remove the agent is also reduced. This allows you to reduce the content of surfactants necessary for such a process, however, with a further decrease in the concentration of surfactants, there is a significant deterioration in the process of removing the agent from fleecy surfaces. The average flavor content is due to the need, on the one hand, to drown out the unpleasant odor of isopropanol, which can partially be retained on fleecy surfaces, and on the other hand, a reduced amount of the used product compared to the bottle.

Example 3. Tobacco tar removal liquid applied to moisturizing wipes.

The kit includes two hermetically sealed bags, one of which contains wet wipes containing fibrous sheet material (including non-woven material) moistened with the above solution from about 150 to about 600 wt.% Based on the dry weight of the above fibrous sheet material, and in the second - standard wet cleaning wipes moistened with a water-based solution (for example, patent RU2163145 or others similar).

Method of use: wipe the surface to be treated with a cloth with the declared product, after 1 min carefully remove the product with a second cloth containing a water-based solution. For fleecy surfaces not applicable. It is allowed to use for processing hands.

The composition of the solution in the composition, wt.%:

propylene glycol 5 nonionic surfactant 0.5 flavor 0.1 isopropanol or ethanol the rest is up to 100%

This product contains the minimum allowable amount of propylene glycol, surfactant and flavoring agent for a more comfortable application to relatively smooth surfaces. Such surfaces do not require leaching of the solution with a large amount of water after a sufficiently long time after processing. On the other hand, a further decrease in the concentration of propylene glycol makes the product dry too quickly and is unpleasant for the skin, a decrease in surfactants leads to incomplete removal of tobacco tar, and with a decrease in the content of the flavor there is a clear smell of isopropanol.
