Description

The present invention relates to improved cleaning compositions for hard surfaces. More specifically, the present invention relates to cleaning compositions for hard surfaces, characterized in that they do not leave significant stains on the surface, are effective against greasy contamination, contain amine oxide surfactant and solvents based on phenyl-containing glycol ethers.

Hard surface cleaners are commercially important products, are used in many fields, and are known as stain cleaners that remove contaminants and deep dirt from surfaces; in particular, such cleaners are suitable for use on hard surfaces. Hard surfaces include surfaces that are commonly found in sanitary facilities, such as equipping sanitary facilities, such as toilets, showers, bathtubs, bidets, sinks, etc., as well as cutting tables, walls, floors, etc. Two types of stains are usually found in the premises of such sanitary facilities, including stains from “hard water”, stains from “soap foam”, and also “stains of rust”. In addition, such hard surfaces and such stains can also be found in other rooms, including kitchens, hospitals, etc. Hard water stains are mineral contaminants caused by the precipitation of salts, such as calcium or magnesium salts, which are usually present in hard water, which is common. Soap foam stains are precipitates of soaps based on fatty acids, such as soaps, which are based on alkaline salts of lower fatty acids. It is known that such fatty acids precipitate in hard water due to the presence of metal salts in it, while leaving an undesirable precipitate on such surfaces. Another type of additional stain, commonly referred to as oily stain, is precipitation on surfaces that typically contain hydrophobic materials, often with additional materials that leave unsightly precipitation on surfaces.

Although the prior art provides various formulations to efficiently clean one or more kinds of stains, usually all stains from the above classes, there is still an urgent need in the art to provide improved hard surface cleaning compositions that are effective in treating many types of stains commonly found on hard surfaces, in particular in a home or commercial environment, especially in kitchens, in or near bathrooms, where Thoth is especially important. These are the very needs to which, in particular, the compositions according to the present invention are directed.

As widely stated, the compositions of the present invention relate to hard surface cleaning compositions that do not leave significant stains on the surface, which are particularly effective for stain-removing from hard surfaces, especially glass or shiny hard surfaces, for example, from reflective hard surfaces.

Particularly preferred are alkyldi (C ₁ -C ₂ ) amine oxides in which the alkyl groups contain about 10-14 carbon atoms and preferably contain 12 carbon atoms, and which are preferably saturated. Particularly preferred is lauryl dimethyl amine oxide, which is present in preferred embodiments of the invention, while excluding the presence of other amine oxides. In the compositions of the present invention, the amine oxide surfactant (s) are present in an amount of about 0.01-1.5% by weight, preferably about 0.1-0.7% by weight, and particularly preferably about 0.3-0 , 55 wt.% By weight of the compositions according to the present invention.

Thus, in particularly preferred embodiments, amine oxide surfactants are the only type of surfactant present in the compositions.

The compositions according to the invention contain at least one of the C ₁ -C ₃ monohydric alcohols, namely methanol, ethanol, n- propanol and isopropanol. One or more of these monohydroxy C ₁ -C ₃ alcohols can be used in an organic solvent system, but preferably the compositions according to the invention contain a monohydroxy C ₁ -C ₃ alcohol, and particularly preferably the monohydroxy C ₁ -C ₃ alcohol is isopropanol, which has been found to be particularly effective. In the compositions according to the invention, monoatomic C ₁ -C ₃ alcohols are contained in an amount of about 0.5-6 wt.%, Preferably about 1.5-5 wt.% And particularly preferably about 2-4 wt.% By weight of the compositions according to the invention . In particularly preferred embodiments, isopropanol is the only monohydroxy C ₁ -C ₃ alcohol present.

in which R represents a C ₁ -C ₆ alkyl group that contains at least one —OH moiety, and R is preferably selected from: CH ₂ OH, CH ₂ CH ₂ OH, CH (OH) CH ₃ , CH (OH) CH ₂ OH, CH ₂ CH ₂ CH ₂ OH, CH ₂ CH (OH) CH ₃ , CH (OH) CH ₂ CH ₃ , CH (OH) CH ₂ CH ₂ OH, CH (OH) CH (OH ) CH ₃ and CH (OH) CH (OH) CH ₂ OH, and the phenyl ring may optionally be substituted with one or more additional moieties, such as C ₁ -C ₃ alkyl groups, but is preferably unsubstituted. A specifically applicable solvent based on phenyl-containing glycol ether is marketed as DOWANOL PPH, described as propylene glycol phenyl ether, which is described by its supplier as a compound with the following structural formula (II):

and, in addition, the supplier indicated that the substance is a basic isomer; which suggests the presence of other alkyl isomers. One or more of these phenyl-based glycol ethers can be used in the organic solvent system, but preferably the compositions of the invention contain one phenyl-based glycol ethers solvent, and it is particularly preferred that the only phenyl-based glycol ethers solvent present in the compositions is is a simple phenyl ether propylene glycol, which, as it was discovered, is extremely effective. In the compositions according to the invention, solvents based on phenyl-containing glycol ethers are contained in an amount of about 0.05-0.85 mass%, preferably about 0.1-0.4 mass%, and particularly preferably about 0.18-0.38 mass % by weight of the compositions according to the invention.

Optionally, but preferably, the compositions according to the invention, in addition, additionally contain one or more organic solvents based on ethers of glycols that do not contain a phenyl fragment. Typical glycol ethers are those containing a common structural fragment R_a-O-R_b-OH in which R_a represents alkyl containing from 1 to 20 carbon atoms, or aryl containing at least 6 carbon atoms; and R_b represents alkylene containing from 1 to 8 carbon atoms, or an ether or polyether containing from 2 to 20 carbon atoms. Typical glycol ethers include propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol isobutyl ether, ethylene glycol methyl ether, ethylene glycol ethyl ether, phenylene glycol butyl ether, diethylene glycol simple butyl ether, propylene glycol, dipropylene glycol monobutyl ether and mixtures thereof. In the compositions according to the invention, organic solvents based on glycol ethers without a phenyl moiety are contained in an amount of about 0-5 wt.%, Preferably about 0.1-2 wt.%, And preferably about 0.95-2.2 wt. %, and particularly preferably about 1-1.75% by weight of the weight of the compositions according to the invention. In particularly preferred embodiments, simplen-propylene glycol butyl ether is the only ether that does not contain a phenyl moiety, namely the only aliphatic organic solvent based on glycol ethers is present.

Moreover, in particularly preferred embodiments of the invention, the compositions contain each of the following components: about 2-4 wt.% Isopropanol, about 0.19-0.4 wt.%, But more preferably about 0.19-0.3 wt.% propylene glycol phenyl ether and about 1-1.5 wt.% n- butyl propylene glycol ether, the presence of which preferably eliminates the presence of any additional organic solvents in the compositions.

The inventor accidentally and unexpectedly discovered that highly effective, mostly aqueous cleaning compositions suitable for cleaning oily hard surfaces, while at the same time leaving, in fact, a small residue on the surface, not leaving significant stains or “not leaving stains”, can be produced at present, especially in the form of compositions that include amine oxide-based surfactants that exclude the presence of additional cationic and anionic surfactants in further, with the systems of preferred organic solvents described herein.

It is desirable that the compositions according to the invention, in fact, did not contain any additional components of organic solvents other than those indicated above.

The compositions also necessarily include one or more alkanolamines, which can provide alkalinity to the compositions, while also providing excellent removal of hydrophobic contaminants that may occur, for example, greasy and oily contaminants. For the purposes of this patent specification, alkanolamines are not considered organic solvents. Typical usable alkanolamines include monoalkanolamines, dialkanolamines, trialkanolamines and alkylalkanolamines such as alkyl dialkanolamines and dialkyl monoalkanolamines. Alkanol and alkyl groups, as a rule, have a chain length from short to medium, that is, from 1 to 7 carbon atoms in the chain. For di- and trialkanolamines and dialkylmonoalkanolamines, such groups can be combined in the same amine, for example, in the preparation of methylethylhydroxypropylhydroxylamine. One skilled in the art can easily identify other members of such a group. The alkanolamine component may be the only alkanolamine or may also be several alkanolamines. It has been found that monoethanolamine, which is effective both as a source of alkaline properties and as a cleaning component, is particularly preferred as the alkanolamine component. In some particularly preferred embodiments of the invention, the alkaline component according to the invention consists of only one alkanolamine, preferably selected from monoalkanolamines, dialkanolamines, trialkanolamines containing from 1 to 7 carbon atoms in the chain, preferably is one monoalkanolamine selected from linear monoethanolamine, monopropanolamine or monobutanolamine, and monoethanolamine is particularly preferred, the presence of which preferably excludes the presence of rugih alkanolamines. In the compositions according to the invention, one or more alkanolamines are contained in an amount of about 0.1-5 wt.%, Preferably about 0.5-2.5 wt.% And particularly preferably 0.5-0.8 wt.% By weight of the compositions according to the invention.

In preferred embodiments of the invention, the compositions include from 0 to about 0.0005 wt.% Antifoam agents, usually silicone-based antifoam agents containing silicone and siloxane polymers, often provided as aqueous emulsions. A particularly suitable antifoam agent is a polydimethylsiloxane composition. It has been found that the incorporation of a small amount of antifoam agent is preferably used in the compositions described herein to reduce the tendency of the compositions to foam so that visible foam, when applied to the surface, is present and observed for a short time, and quickly collapses and dissipates without leaving unwanted deposits on the treated surface. Although such anti-foam components may be excluded from the compositions indicated herein, they are preferably present in amounts of from about 0.0001 to 0.002% by weight based on the weight of the silicone and / or siloxane compounds in the compositions of which they are a part. It has been unexpectedly discovered that even such minor amounts of such a component are effective.

In preferred embodiments of the invention, the compositions include a hydrotropic substance, which primarily performs the function of improving the solubility of any flavoring component present in most of the aqueous compositions mentioned herein. Such a component may be omitted, however, if required, it is preferably present. Typical hydrotropic substances include, but not limited to, benzenesulfonates, naphthalenesulfonates, C ₁ -C ₁₁ alkylbenzenesulfonates, naphthalenesulfonates, C ₅ -C ₁₁ alkylsulfonates, C ₆ -C ₁₁ alkyl sulfates, alkyl diphenyl oxide disulfonates and hydrotropic compounds. The hydrotropic compounds of the invention are often provided in the form of salts with a suitable counterion, such as one or more alkali or alkaline earth metals, such as sodium or potassium, especially sodium. However, other water-soluble cations, such as ammonium ions, lower mono-, di- and trialkyl, i.e., C ₁ -C ₄ alkanolammonium groups, can be used instead of alkali metal cations. Typical alkylbenzenesulfonates include, for example, isopropylbenzenesulfonates, xylene sulfonates, toluenesulfonates, cumene sulfonates, and mixtures thereof. Typical C ₅ -C ₁₁ alkyl sulfonates include hexyl sulfonates, octyl sulfonates and hexyl / octyl sulfonates and mixtures thereof. Particularly useful hydrotropic compounds include benzenesulfonates, o-toluenesulfonates, m- toluenesulfonates and p- toluenesulfonates; 2,3-xylene sulfonates, 2,4-xylene sulfonates and 4,6-xylene sulfonates; cumene sulfonates, where such typical hydrotropic substances are typically in the form of their salts, including sodium and potassium salts. Despite the fact that such hydrotropic substances may be excluded from the compositions indicated here, they are preferably present in amounts of from about 0.001 to 2 wt.%, Preferably from about 0.01-0.5 wt.% And particularly preferably from about 0.1 -0.3 wt.% By weight of the compositions according to the invention.

The compositions according to the invention may contain up to about 10 wt.% In total, preferably about 5 wt.% In the amount of one or more conventional additives selected from colorants, flavors and solubilizers of flavors, viscosity modifiers, including one or more thickeners, pH adjusters and pH buffers, including organic and inorganic salts, optical brighteners, abrasives and preservatives, as well as other optional components known in the art. However, it is preferable that any such traditional additional component, which undesirably reduces the preferred characteristics of the invention, relating to the ability not to leave significant stains, is specifically excluded from the compositions.

Preservatives in minor amounts can also be added to the compositions of the invention, for example, including preservatives sold under the trademarks Kathon ^® CG / ICP (Rohm & Haas, Philadelphia Pa.), Suttocide ^® A (Sutton Labs, Chatham NJ), and ^{Midtect ® TFP (Tri-K Co.} , Emerson, NJ). Such preservatives can be included in minor amounts, for example, from 0.0001 to about 0.5 wt.% Of the total weight of the concentrated composition, usually in an amount of about 0.1 wt.% Or less, and preferably, preservatives are present in amounts of about 0, 05 wt.% And less.

Concentrated compositions according to the invention are optional, but in some cases it is desirable to include a flavoring component. Flavoring compositions upon receipt from the supplier may be provided in the form of an aqueous composition or a composition solvated in an organic solvent, and may include, as a hydrotropic substance or emulsifier, a surfactant, usually a minor surfactant, usually not more than about 1 5 wt.%. Such a flavoring component may be present in any effective amount, but is usually contained in an amount of not more than 2% by weight, preferably not more than 1% by weight of the composition.

Thickening agents such as clays, crosslinked acrylic polymers, for example CARBOPOL, gums, celluloses, including modified celluloses, and the like. it is desirable to exclude from the compositions as such, since it is assumed that they reduce the preferred characteristics of the preferred embodiments of the invention associated with the ability of the compositions not to leave significant stains on the treated surface.

Similarly, abrasive materials, such as: oxides, such as calcined aluminum oxides and the like, carbonates, such as calcium carbonate and the like, silica powder, siliceous chalk, diatomaceous earth, colloidal silicon dioxide, alkaline metasilicates, such as sodium metasilicate etc., perlite, pumice, feldspar, calcium phosphate, organic abrasive materials based on fine particles of polymers or in the form of particles of polymers, especially based on one or more polyolefins, polyethylene, polypropylene, complex polyesters, polystyrenes, acetonitrile butadiene styrene resins, melamines, polycarbonates, phenolic resins, epoxies and polyurethanes, natural materials such as rice husks, corncobs, etc. or talc and mixtures thereof, etc. it is desirable to exclude as such, since it is assumed that they reduce the preferred characteristics of the preferred embodiments of the invention associated with the ability of the compositions not to leave significant stains on the treated surface.

In some particularly preferred embodiments of the invention, organic acids are specifically excluded from the compositions according to the invention, for example citric, malic, succinic, lactic, glycolic, fumaric, tartaric, formic, etc.

The compositions according to the invention may include one or more pH adjusting agents or compounds that can be used to adjust the pH of the compositions or to impart buffering properties to the compositions of which they are a part within a certain pH range. However, usually such means are not necessary due to the inclusion in the composition of the alkanolamine component, which gives the compositions alkaline properties.

In some particularly preferred embodiments of the invention, inorganic acids are specifically excluded from the compositions according to the invention, for example, sulfuric acid, phosphoric acid, potassium dihydrogen phosphate, sodium dihydrogen phosphate, sodium sulfite, potassium sulfite, sodium pyrosulfite (sodium metabisulfite), potassium pyrosulfite (potassium metabisulfite), acidic sodium hexametaphosphate, acidic potassium hexametaphosphate, acidic sodium pyrophosphate, acidic potassium pyrophosphate, hydrochloric acid and sulfamic acid. Other water-dispersible or water-soluble inorganic or mineral acids, not specifically mentioned here, it is also desirable to exclude from certain preferred embodiments of the compositions according to the invention.

The compositions according to the invention are high-water and contain at least 90 wt.% Water, which is preferably distilled, demineralized, but deionized water is particularly preferred.

The compositions according to the invention are easily flowable, easily pumped and liquid at room temperature, having a viscosity in the range of from about 1 cps to about 50 cps in such environmental conditions.

The compositions typically have a pH in the range of about 9.5-11.5, preferably in the range of about 10.5-11.35.

In particularly preferred embodiments, the present invention provides hard surface cleaning compositions comprising (preferably consisting of, or essentially consisting of):

- about 0.01-1.5 wt.% one or more amine oxide surfactants;

- approximately 0.5-6 wt.% monatomic primary C ₁ -C ₃ alcohol,

- from 0 to about 0.005 wt.%, preferably about 0.0001-0.002 wt.%, an anti-foam component based on silicone;

- from 0 to about 0.5 wt.% hydrotropic substances;

- at least 90 wt.% water;

- and optionally one or more additional traditional additives, the amount of which in total does not exceed approximately 10 wt.% of the mass of the total composition of which they are a part.

The compositions are easily produced by any method from a number of methods known in the art. For convenience, a portion of the water is supplied to a suitable mixing tank, optionally equipped with a stirrer or means for mixing, and the remaining components are added to the mixing tank with stirring, including any final amount of water necessary to provide 100 wt.% Of the composition according to the invention.

It may be desirable to provide the composition obtained according to the invention in the form of a consumer product that can be opened manually and stored in a refillable container, which can either be solid or can be a deformable “plastic bottle with a tip” type dispenser. However, it is preferable that the composition is preferably provided in a bottle, bottle or other container and dispensed is distributed on a solid surface that requires processing using a handpiece or pump, for example, a pump suitable for manual use, or a trigger spray suitable for manual use. The compositions according to the invention can also be provided in a container under pressure, for example, in an aerosol can with a suitable amount, usually up to about 10 wt.%, Based on the weight of the composition according to the invention, of an aerosol propellant, for example, a hydrocarbon containing from 1 to 10 carbon atoms such as n- propane, n- butane, isobutane, n- pentane, isopentane and mixtures thereof, or a non-hydrocarbon gas, for example, CO ₂ , N ₂ , etc., or essentially even compressed air.

Since the compositions according to the invention are preferably used for cleaning hard surfaces, it is desirable to provide a cleaning composition for hard surfaces according to the invention as a ready-to-use product that can be applied directly to a hard surface. The composition can be applied directly from the container with the product in the form of a liquid, or it can be applied using a cloth pre-impregnated with a certain amount of the composition. Cleaning a hard surface can be accomplished by applying an effective amount of a cleaning composition according to any one of the preceding paragraphs, and then optionally wiping the treated hard surface to remove at least a portion of the composition from the hard surface.

By way of non-limiting examples, hard surfaces include surfaces consisting of heat-resistant materials, such as: glazed and unglazed tiles, bricks, porcelain, ceramics, as well as stone, including marble, granite and other stone surfaces; glass; metals; plastics, for example, polyester, vinyl, fiberglass and other hard surfaces known in the industry. Hard surfaces, which should be especially noted, are surfaces usually found in sanitary facilities, for example, in the equipment of sanitary facilities, in shower cabins, bathrooms and bath equipment (shelves, partitions, shower doors, shower racks), toilets, bidets, surfaces walls and floors, as well as surfaces related to kitchen facilities, and other areas related to cooking, including built-in furniture and surfaces on cutting tables, as well as surfaces on walls and floors, especially surfaces that include yuchayut a heat-resistant materials, plastics, Formica ^®, Corian ^® and stone. The compositions according to the invention are particularly effective for cleaning glossy or reflective surfaces, for example glossy enameled surfaces, glossy ceramic surfaces, glass, mirror surfaces, metals and shiny metal surfaces and the like.

The compositions obtained according to an illustrative example include the components listed below. The compositions obtained according to an illustrative example demonstrate a particularly preferred embodiment of the invention, as well as preferred mass percentages as well as preferred relative mass percentages / mass ratios regarding the respective individual components present in the composition.

EXAMPLES

Examples of compositions for treating hard surfaces according to the invention are described in the following table 1; the components shown in table 1, used to obtain the compositions, were used on the basis of materials in the form "how (they) are delivered"; the composition of such components is described in more detail in table 2. Compositions for treating hard surfaces were obtained by mixing in a beaker at room temperature in water the components shown in table 1, which were mixed using a traditional magnetic stirrer or paddle stirrer; mixing was continued until the composition became homogeneous in appearance. It should be noted that the components can be added in any order, however, it is preferable that the first pre-prepared mixture consisted of any flavoring component with one or more surfactants and / or hydrotropic substances in a certain amount of water used in compositions for treating hard surfaces according to invention. The order of addition is not particularly important, but good results are obtained when surfactants (which may also be a pre-prepared mixture of flavoring and surfactants) are added to water before the remaining components are added. The amounts of said components are indicated in mass / mass% based on the total weight of the composition for treating hard surfaces of which they are a part. The total amount of water present in each composition is based on the amount of water provided by one or more of the components mentioned.

Assessment of cleaning from greasy contaminated heat treated

The effectiveness of the compositions according to the present invention (example "E2"), as well as the compositions of the comparative examples based on commercial products, were evaluated according to the following test protocol, which was used to evaluate the cleaning efficiency of heat-treated, complex greasy contaminants on hard surfaces.

“Heat-treated greasy test contaminants” were obtained from “Part I” and “Part II” contaminants, which were prepared as described below.

Part I contamination was obtained by mixing together the ingredients shown in the following table

Part I Pollution mass./mass.% Peanut butter 26.2 Corn oil 14.5 Cherry pie filling 14.5 Ground beef 14.5 Minced pork 14.5 Accent ^® flavor enhancer (monosodium glutamate) 0.60 Table salt 0.60 Deionized water 14.6

Followed by heat treatment of the mixture in a glass baking dish at 400 ° F (205 ° C) for 2 hours. Part I contamination was allowed to cool to 100 ° C or lower. Upon receipt, the contamination of Part I can be aliquoted for later use and frozen in glass jars. If a frozen aliquot was used later, it was first heated in a hot water bath to 100 ° C and mixed or shaken before mixing with the right amount of Part II contamination.

Part II contamination was Kitchen Bouquet ^® sauce, a commercially available bottled food product used to enhance flavor and color; it is believed that it is primarily a burnt sugar, which is used in the form "as supplied" from the manufacturer.

The heat-treated test grease used for the evaluation was mixed immediately before the test tiles were contaminated by combining 83.3 wt.% Of Part I contamination at 100 ° C and 16.7 wt.% Of Part II in a beaker for at least 5 minutes using a manual homogenizer.

As test substrates, white enamelled tiles with porcelain coating (4 × 4 inches) were used. All enameled tiles were first cleaned with a mild dishwashing detergent, wiped with ethanol, placed on vertical shelves, and allowed to dry and cool to room temperature of approximately 68 ° F (20 ° C).

The heat-treated oily test contaminants were heated to 100 ° C in a water bath and kept homogenized during application to the test tiles to avoid deposition of the test contamination. Before applying the test contamination, each tile was weighed. The test contamination was then applied to dry test tiles by applying 0.75 grams (+/- 0.10 grams) to the porcelain surface of each test tile using a small kitchen brush to sprinkle the roasted meat, which was used to evenly distribute the contamination. After application, the test tile was reweighed to ensure that at least 0.75 grams of contamination was applied to the tile. If necessary, a few additional drops of heat-treated greasy contamination were applied to the tile, leveled with a brush and the tile was re-weighed to ensure that at least 0.75 grams of the heat-treated greasy contamination was applied to the tile. This procedure was repeated until at least 0.75 grams of heat-treated greasy soiling was applied to the tile. Then the tile was placed on a metal pan and covered with a lid before subsequent heat treatment. When enough test tiles were coated with the required amount of heat-treated greasy contamination, the lid-covered tiles were heat treated in a convection oven at 300 ° F for 90 minutes to further cure the heat-treated greasy contamination for testing. After 90 minutes, the trays were pulled out of the oven, the covers removed and the tiles allowed to cool for at least 12 hours (usually overnight) before being used to evaluate the degree of cleaning using a typical composition.

Cellulose test sponges with a standard size of approximately 10 x 7.6 cm were subjected to three cycles of washing and centrifugal drying in a household washing machine to ensure that all contaminants, detergents or other contaminants are washed off the sponges. After the third cycle of centrifugal drying, the sponge was pulled out of the aforementioned machine and placed in a tightly closed plastic container to maintain cleanliness as well as its relative humidity prior to its use in the test to assess the degree of cleaning.

To assess the degree of cleaning, a contaminated test tile prepared as described above was placed in a wet abrasion test apparatus with a SHEEN scrub (ref: 903PG) and fixed. Before use, moistened sponges were wrapped on top with a non-porous polymer film in order to protect the sponges and provide a liquid barrier between the sponge and the composition to be tested. Each test composition (formulations of Example E2, and also for each comparison example) in an amount of 50 ml was loaded onto a sheet of dry tissue paper of the same size, for example, a dry paper towel, which was then wrapped around a sponge wrapped with a plastic film, and then placed in a holder test apparatus SHEEN. A weight of 200 grams was added to each of the sponge holders to ensure compression of the sponge and good cleaning of the surface of the contaminated test tiles with a wet paper towel. Then, the SHEEN testing apparatus was turned on and adjusted so as to provide 3 cleaning cycles (6 linear movements on the surface) over the test contamination on the test substrate; then the test substrate was removed, rinsed with approximately equal amounts of tap water, and dried with compressed air from the airbrush compressor. This test for each composition was repeated several times to provide at least 3 reproductions for each test composition.

The cleaning efficiency of the tested compositions was evaluated using a high resolution digital image reproducing system that evaluated the light reflection characteristics of each treated test substrate. Such a system used a photocopy tripod located on a backlit protected viewing table, which provided diffused reflected light supplied by two 15-watt, 18-inch T8 type fluorescent lamps with a nominal color temperature of 4100K, which approximates to "natural sunlight", as noted by the manufacturer. Two fluorescent lamps were located parallel to each other, placed parallel and at a distance from two opposite side edges of the test substrate (test tiles) and in a common horizontal plane parallel to the upper surface of the test substrate for which the assessment was made, and between the upper surface of the tile and the front of the lens of the CCD camera. The CCD camera was a QImaging Retiga CCD camera with a Schneider-Kreuznach Cinegon Compact Series lens, f.r. 9/10 mm, 1 inch size (Schneider-Kreuznach model # 21-1001978), the CCD camera was equipped with a tripod for viewing copies with a lens pointing down towards the table of the tripod for copies, on which the treated test substrate was placed directly under the lens. The illumination of the illuminated viewing table protected the tripod for viewing photocopies, two 18-inch fluorescent lamps and a lockable door that allows you to insert, place and remove the processed test substrate, while the door was closed during the exposure of the CCD camera when shooting the processed test substrate. Thus, the influx of light from the outside and the variability of the light source during the evaluation of the series of test substrates were minimized, and the exposure and observation errors using the CCD camera were minimized.

The CCD camera was connected to the personal computer via the Firewire IEEE 1394 interface, and the exposure data from the CCD camera was read using the computer program "Media Cybernetics Image Pro Plus version 6.0", which was used to evaluate images obtained using the CCD camera, which then analyzed according to the following equation. The percentage of removal of contaminants from each treated test substrate was determined using the following equation:

% delete = RC-RS × 100 RO-RS

where RC = Reflection coefficient of the tile after cleaning with the test product;

RO = Reflection coefficient of the original contaminated tile;

RS = Reflection coefficient of contaminated tiles.

The results of this assessment were averaged for each of the tested formulations, and the evaluation results are shown in the following table 3.

Drying speed and staining

The test for the formation of stains and characteristics associated with the drying of some of the compositions described in table 1, was carried out according to the following test report.

Before applying the test composition, a 12 inch × 12 inch glass mirror tile was cleaned and thoroughly rinsed with water to ensure removal of any surface deposits; then the mirror surface was wiped with alcohol, applied with a laboratory disposable wipes (Kimwipe ^®, of Kimberly-Clark, Inc.), containing no fluff (lint).

Then provided the amount of each test product in an incompressible bottle equipped with a trigger spray. Then, the cleaned and prepared mirror was placed on a horizontal laboratory table and a metered amount of the test composition was manually pumped once using a trigger sprayer. Immediately after applying the composition, the mirror was wiped using a standard sheet of paper towel, bent once to form a 3.5 × 5 inch rectangle, and 6 circular motions for uniform distribution over the mirror surface; then the napkin was immediately turned over and used to wipe the mirror along a zigzag path from the top of the mirror to the bottom, according to which, the napkin moved downward while continuously moving along a zigzag path with 4 passes. A specialist in the field immediately observed the mirror to evaluate the time / speed of drying and the degree of formation of stains. The results are presented in table 3.

As for the drying speed, this characteristic of the test composition was evaluated according to the following scale: a rating of "10" points indicated the total drying time of the product within approximately 3 seconds; a score of "9" points indicated the total drying time of the product within approximately 6 seconds; a rating of "8" points indicated the total drying time of the product within approximately 9 seconds; a score of "7" points indicated the total drying time of the product within approximately 12 seconds; a rating of "6" points indicated the total drying time of the product within approximately 15 seconds; a rating of "5" points indicated the total drying time of the product within approximately 18 seconds; a rating of "4" points indicated a total drying time of the product within approximately 21 seconds; a rating of "3" points indicated the total drying time of the product within approximately 24 seconds; a rating of "2" point indicated a total drying time of the product within approximately 3 seconds and a rating of "1" rating indicated a total drying time of the product within approximately 30 seconds or more.

As for the assessment of the formation of stains, it was evaluated after drying of the test composition on the surface of the mirror tile. The assessment of the formation of stains was based on a linear scale with the following two extreme points: the "best characteristic" was rated at "10" points, indicating the absence of visible stains / deposits on the surface and the surface appearance equivalent to the mirrors prepared for testing, which were washed and rubbed with alcohol; and the “worst performance” was rated “2” and was equivalent to the performance of the FLASH cleaner (Procter & Gamble Co., United Kingdom), a commercially available trigger spray cleaner and degreaser that leaves a solid visible residue on the mirror surface. All intermediate values were evaluated by an expert member of the working group with respect to the two mentioned extreme points. The results obtained are also shown in Table 3.

As can be seen from the above table, the compositions according to the invention, especially E1, E3, E5 and E6 at the same time provided both excellent cleaning of greasy surfaces and did not leave streaks in essence and gave a small precipitate on the test substrates after cleaning. Surprisingly, the compositions according to the invention provided a better cleaning quality than the commercially available FLASH cleaner, which has a high degree of staining on the surface but satisfactorily cleans greasy surfaces; the compositions did not leave significant stains on the surface, and the fast drying characteristics were comparable to the commercially available VIGOR glass cleaning product (Eau Ecarlate S.A.S., France).
