The present invention relates to liquid compositions for cleaning and/or deep cleaning of various surfaces animate and inanimate objects, including hard surfaces in and around the home, surfaces, utensils, surfaces, hard and soft tissues of the oral cavity, for example surfaces of the teeth, gums, tongue and cheeks, the skin of humans and animals, surfaces, cars and vehicles, etc. More specifically, the present invention relates to liquid cleaning compositions containing particles for cleaning and/or deep cleaning.

The level of technology

Cleaning compositions, such as compositions of particles or liquid formulations (including gel, a paste containing abrasive components, well known in the art. Such compositions are used for cleaning and/or deep cleaning of various surfaces, particularly those surfaces, which are usually contaminated difficult to remove spots and dirt.

Among currently known cleaning compositions, the most popular of them are based on the abrasive particles with different shapes, from spherical to irregular in shape. The most common abrasive particles are either inorganic, such as a carbonate salt, clay, silica, silicate, oil shale ash, perlite and silica pesos is, or organic polymeric beads, such as polypropylene, PVC, melamine, urea, polyacrylate and derivatives, and come in the form of a liquid composition with a creamy consistency with abrasive particles, suspendibility in them.

The safety profile of the surface of such currently known cleaning compositions inadequate, alternative, poor cleaning characteristics are shown for compositions with adequate security profile of the surface. Indeed, due to the presence of very hard abrasive particles, these compounds can cause damage, such as scratching, the surface to which they were applied, while in the less rigid the material, the level of cleaning characteristics are insufficient. In fact, the developer must choose between good feature of cleaning/deep cleaning, but having a strong surface damage or compromise the characteristics of the cleaning/deep cleaning, while maintaining acceptable safety profile of the surface. In addition, such known in the present cleaning compositions, at least in some applications (for example, cleaning a solid surface) are perceived by consumers as deprecated.

Thus, the aim of the present invention is to provide a liquid composition for cleaning and/or deep cleaning, is acceptable for cleaning/deep about isdi various surfaces, including surfaces animate and inanimate objects, hard surfaces in and around the home, surfaces, utensils, surfaces, hard and soft tissues of the oral cavity, such as teeth, gums, tongue and cheeks, the skin of humans and animals, etc. where the composition provides a good description cleaning/deep cleaning, at the same time providing a good safety profile of the surface.

It was found that the above objective can be satisfied with the composition in accordance with the present invention.

The advantage of the compositions in accordance with the present invention is that they can be used for cleaning/deep cleaning surfaces animate and inanimate objects made of different materials, such as glazed and unglazed ceramic tiles, enamel, stainless steel, Inox®, Formica®, vinyl, no wax vinyl, linoleum, melamine, glass, plastics, painted surfaces, the skin of humans and animals, the hair, the surface of the hard and soft tissues of the oral cavity, such as teeth, gums, tongue, cheeks, etc.

An additional advantage of the present invention is that the compounds in this application, the particles can be expressed at very low levels, providing at the same time the above-mentioned advantages. Indeed, in General, for others it is the guy, high levels of abrasive particles needed to achieve good characteristics cleaning/deep cleaning, which leads to high cost of development and process incompatibilities with many packages, such as plastic bottles or spray bottles, cheap ergonomics of use, complexity washing profiles and final cleaning, as well as the limits for aesthetic properties and pleasant to the touch of the composition of the cleaning/deep cleaning.

Abrasive cleaning particles

A liquid composition for cleaning and/or deep cleaning in this application contains abrasive cleaning particles, which are selected or synthesized to show effective forms, for example, determined by the roughness and adequate hardness.

In the preferred implementation of the abrasive cleaning particles is preferably not roll down. Additionally, in the preferred implementation of the abrasive cleaning particles are preferably sharp.

The applicant has found that not skatyvayasj and sharp abrasive cleaning particles provide good removing dirt and small damage surfaces. Indeed, the applicant has discovered that a very specific form of particles, for example, defined roundness, contribute to the effective slip abrasive particles compared to typical abrasive particles, which is likely to contribute to the movement of rolling and less effective at moving the dirt from the surface. Roundness must meet the criteria to facilitate effective the WMD slip particles in the range from 0.1 to 0.45.

The form of abrasive cleaning particles can be defined in different ways. The present invention determines the shape of the cleaning particles in the form of particles, which displays the geometric proportions of the particles and more pragmatic population of particles. The most recent analytical methods allow accurate simultaneous measurement form particles large number of particles, typically, more than 10,000 particles (preferably more than 100000). This enables fine adjustment and/or selection of the average population of particles with discriminatory characteristic. This measurement the analysis of the particle shape perform on Occhio 500 Nano Particle Characterization Instrument with the accompanying software Callistro version 25 (Occhio sa. Liege, Belgium). This tool is used for preparation, dispersion, image acquisition and analysis of samples of particles, according to the manufacturer's instructions, and the following settings instrument settings: White prescribed = 180, vacuum time = 5000 MS, settling time = 5000 MS, automatic threshold, the number of particles taken into consideration/analysis = from 8,000 to 500,000, the minimum number of duplicates per sample = 3, setting of the lens 1x/1.5x.

Abrasive cleaning particles according to the present invention are determined by a quantitative description of the shape. In the quantitative description of the descriptor form is understood as a quantity that can be calculated is from images of the particles or the physical properties of the particles using mathematical and numerical operations. While the shape of the particle can be defined in 3 dimensions selected analytical method, the applicant has found that the characteristics of the particle shape in 2 dimensions are the most relevant and correlated with the abrasive characteristic of the cleaning particles. During Protocol analysis of the particle shape, particle Orient to the surface by gravity sedimentation is similar to the expected orientation of the particles during the cleaning process. Thus, the purpose of the present invention relates to characteristics of 2-D shape particles/population of particles, as determined by the projection of their forms on the surface on which the particle/population of particles precipitated.

In the preferred implementation of the abrasive cleaning particles have an average ECD of from 10 μm to 1000 μm, preferably from 50 μm to 500 μm, more preferably from 100 μm to 350 μm, and most preferably from 150 to 250 microns.

Moreover, the applicant has found that the size of the abrasive particles can be crucial for achieving the characteristics of an effective cleaning while overly abrasive population with small particle sizes, for example, typically below 10 microns, has a polishing effect compared to treatment, despite the characterization of a large number of particles on the content of the particles in the cleaning solution, the inherent small size of the particles. With d the natives hand, abrasive population with a significantly larger particle size, for example more than 1000 μm, does not provide optimum cleaning performance, as the number of particles on the content of the particles in the cleaning solution decreases significantly as the inherent large size particles. Additionally, an excessively small particle size is not desirable in the task of cleaning/deep cleaning, since, in practice, small and numerous particles are often difficult to remove from surfaces of different topologies that require excessive force to remove them from the user, if only to leave the surface with visible residue particles. On the other hand, too large a particle too easy to detect visually or she provides poor tactile experience while operating or using the cleaner. Therefore, the applicant identifies in this application, the optimum range of particle sizes, which provides both the characteristics of a good cleaning, and use.

The abrasive particles have a size that is determined by their equivalent area diameter (ISO 9276-6:2008(E) section 7), also called the equivalent circular diameter ECD (ASTM F1877-05 section 11.3.2). The average ECD of the population of particles is calculated as the average value of the respective ECD of each particle of the population of particles of at least 10,000 particles, preferably more than 50,000 shall astiz, more preferably more than 100,000 particles after excluding from the measurement and calculation data of particles having an equivalent area diameter (ECD) below 10 micrometers. Secondary data is derived from measurements based on volume compared with measurements based on quantities.

In one of the preferred examples, the size of the abrasive cleaning particles used in the present invention, change in use, especially when a significant reduction in size. Thus, the particle remains visually or tactilely detectable in the liquid composition and in the beginning of the process used to ensure effective cleaning. In the process of cleaning the abrasive particles are dispersed or dissolved into smaller particles and become invisible to the eye or tactile undetectable.

In the present invention, the shape descriptors are the calculations of the geometric descriptors/form factors. The geometrical form factors are ratios between two different geometric properties, such properties are, typically, is a measure of the proportions of the image of the whole particle or measure of perfect geometric proportions of the body covering part of or form a shell around the particle. This leads to the formation of descriptors macroform similar to the aspect ratio, however, the applicant found what about the handles mesoform - a concrete subclass handles macroform is especially critical for the performance characteristics of cleaning and security settings of the surface of the abrasive cleaning particles, while a more typical form parameters, such as aspect ratio, was not enough. These descriptors mesoform describe the different particles compared to the ideal geometric form, especially as different as compared with the sphere, and, incidentally, help to determine their ability for the lack of a slide, such as slide, effective model of treatment. Abrasive cleaning particles according to the present invention differ from the typical spherical or similar to spherical, such as granular, abrasive forms.

Abrasive cleaning particles according to the present invention are non-spherical.

Non-spherical particles in this application preferably have sharp edges, and each particle has at least one edge or surface having a concave curvature. More preferably, the non-spherical particles in this application have many sharp edges, and each particle has at least one edge or surface having a concave curvature. The sharp edges of nonspherical particles is defined as the region having a radius of less than 20 μm, preferably menee μm, most preferably less than 5 microns. The radius is determined by the diameter of the imaginary circle corresponding to the curvature of the trailing edge.

The Figure 1 illustrates the radius of curvature.

Roughness

Roughness is a quantitative 2-dimensional description of the image analysis forms and is measured in accordance with ISO 9276-6:2008(E) section 8.2 implemented using Occhio 500 Nano Particle Characterization Instrument with the accompanying software Callistro version 25 (Occhio sa. Liege, Belgium). Roughness defines the 2D measurement, equivalent to the useful surface area of the outside surface of the core particles, and can vary in the range from 0 to 1, where the roughness value of 0 describes a particle with unprofitable mass, available on the periphery of the core particles. Roughness is also sometimes called satelliteto, and it represents a quantitative description, and is available to handle mesoform, for example, in Occhio Nano 500 instrument.

Roughness useful in abrasive particles as non-spherical particle in this application is preferably a large mass of material available on the periphery of its core, useful as abrasives. This peripheral mass is useful for effective cleaning and to prevent rolling of the particles.

The roughness is determined in 2D dimensions equivalent to the useful surface area outside surface of the core particles in the range 0-1, while the roughness of 0 describes a particle with unprofitable mass, available on the periphery of the mass of the nucleus particles. Roughness is calculated as follows:

Rgγ=(A-A(Oγ)/A,

where A represents the size of the particles and A(Oγ) is the surface area, which is considered the "core"particles. A-A(Oγ) is the "effective area on the periphery of the particle, and the surface roughness represents the share of such useful area compared to the total area of the particles. Oγ is called tunable tolerance factor and is typically set at 0,8, therefore, the definition of roughness is a Rgγ=(A-A(0,8)/A. in order to compute A(0,8), the maximum number of disks inside a contour of a particle at each point of the edge of the particle. Size, for example a square inscribed disks is determined by the diameter of the disks, while the value of the diameter varies from 0.8×Dmax up to Dmax (where Dmax is the value of the diameter of the largest disc, inscribed in the particle). Size of the core particles A(0,8) is determined by the square of the corresponding projections of all inserted discs.

Figure 2 is a drawing showing how to calculate the roughness of the particles.

The applicant has found that the abrasive cleaning particles with an average roughness of from 0.1 to 0.3, preferably from 0.15 to 0.28, and more preferably from 0.18 to 0.25 ensure increased the military characteristics of clean and safe surface. Average data obtained from measurements on the basis of volume compared with measurements based on quantities.

Thus, in a preferred implementation of the present invention the abrasive particles in this application have an average roughness of from 0.1 to 0.3, preferably from 0.15 to 0.28, and more preferably from 0.18 to 0.25.

Roundness

Roundness is a quantitative 2-dimensional description of the image analysis forms and is measured in accordance with ISO 9276-6:2008(E) section 8.2 implemented using Occhio 500 Nano Particle Characterization Instrument with the accompanying software Callistro version 25 (Occhio sa. Liege, Belgium). Roundness is the preferred descriptor mesoform and widely available tool for the analysis of forms, such as in Occhio Nano 500 or in Malvern Morphologi G3. Roundness is sometimes described in the literature as the difference between the shape of the particles and the perfect sphere. The roundness values are in the range from 0 to 1, where the roundness 1 describes perfectly spherical particles or particles in the form of a disk, measured in a two-dimensional image.

$$C=\sqrt{\frac{4\pi A}{P^2}}$$

where a is the projected area, which is a 2D descriptor, and P represents the perimeter length of the particles.

The applicant is spruce found that the abrasive cleaning particles having an average circularity from 0.1 to 0.4, preferably from 0.15 to 0.35 and more preferably from 0.2 to 0.35, provide superior cleaning performance and safety surface. Average data obtained from measurements on the basis of volume compared with measurements based on quantities.

Thus, in a preferred implementation of the present invention the abrasive particles in this application have a mean circularity from 0.1 to 0.4, preferably from 0.15 to 0.35 and more preferably from 0.2 to 0.35.

Strength

Durability is quantitative 2-dimensional description of the image analysis forms and is measured in accordance with ISO 9276-6:2008 (E) section 8.2 implemented using Occhio 500 Nano Particle Characterization Instrument with the accompanying software Callistro version 25 (Occhio sa. Liege, Belgium). Nonspherical particle in this application preferably has at least one edge or surface having a concave curvature. Strength is a parameter metformi, which describes the General concavity of the particle/population of particles. Values of strength are in the range from 0 to 1, where a value of strength 1 describes neognathous particle, measured in the literature as:

Strength = A/Ac,

where A represents the size of the particles, and Ac is the area of the convex hull bounding h is sticu.

The applicant has found that the abrasive cleaning particles with an average strength of from 0.4 to 0.75, preferably strength from 0.5 to 0.7 and more preferably from 0.55 to 0.65 provide improved cleaning characteristics and safety surface. Average data obtained from measurements on the basis of volume compared with measurements based on the number.

Thus, in a preferred implementation of the present invention the abrasive particles in this application have an average strength of from 0.4 to 0.75, preferably strength from 0.5 to 0.7 and more preferably from 0.55 to 0.65.

In a highly preferred implementation of the abrasive cleaning particles have an average roughness of from 0.1 to 0.3, preferably from 0.15 to 0.28, and more preferably from 0.18 to 0.25), and the average circularity from 0.1 to 0.4, preferably from 0.15 to 0.35 and more preferably from 0.2 to 0.35) and/or the average strength of 0.4 to 0.75 (preferably a strength of from 0.5 to 0.7 and more preferably from 0.55 to 0.65).

Strength is sometimes also called "bulge" in the literature or in a hardware software, using the formula strength in the place of its definition, described in ISO 9276-6 (convexity = Pc/P, where P represents the perimeter length of the particles, and Pc represents the length of the perimeter of the convex hull shell, limiting particle). Although the strength and convexity are similar descriptors metformi concept the Complainant refers in this application to measure the strength expressed above Occhio Nano 500, as described above.

The term "average circularity", "average strength" or "average roughness" applicant considers the average roundness or strength or roughness of each particle taken from a population of at least 10,000 particles, preferably more than 50,000 particles, more preferably more than 100,000 particles, after exclusion of measurements and calculations, roundness or strength or roughness of the particles with an equivalent area diameter (ECD) below 10 microns. Average data obtained from measurements on the basis of volume compared with measurements based on quantities.

Abrasive particles made from the following material or a mixture of abrasive material, typically known in the art, such as, but not exhaustive, for example, abrasives organic or inorganic salts, such as carbonate salt derivatives, phosphate derivatives, salts, pyrophosphate-derived salts, silica or alumina, hydroxyapatite, diatomaceous earth, ordinary earth, talc, etc., polymeric abrasives containing polyethylene, polypropylene, PVC, polycarbonate, melamine, urea, polyurethane, polyacrylate, polystyrene, phenol-aldehyde resin, polyether, polyamide or natural abrasives by the scientists from cellulose, lignocellulose or shell, such as nut shell, Apple seeds, olive kernel, apricot seeds, core, wood, bamboo and plants.

Preferably the abrasive particles are made of a polymeric material selected from the group consisting of polyethylene, polypropylene, PVC, polycarbonate, melamine, urea, polyurethane, polyacrylate, polystyrene, phenol-aldehyde resins, polyesters, polyamide and their blends and natural abrasives derived from cellulose, lignocellulose or shell, such as nut shell, Apple seeds, olive kernel, apricot seeds, core, wood, bamboo and plants, and their mixtures. More preferably, the abrasive particles are made of a polymeric material selected from the group consisting of polyethylene, polypropylene, PVC, polycarbonate, melamine, urea, polyurethane, polyacrylate, polystyrene, phenol-aldehyde resins, polyesters, polyamide and mixtures thereof. Even more preferably the abrasive particles are made of a polymeric material selected from the group consisting of polyurethane, polyester, polyacrylate, polystyrene and mixtures thereof. Most preferably the abrasive particles are made of rigid polyurethane foam obtained from a diisocyanate (for example, Lupranate M200R or Lupranate M20S) and diol (Lupranol 3423).

Typical methods of deformation or fracture turned to what I specified above material in the abrasive powder, having a useful form, determined by the target range of roughness that could be used more preparation, for example, methods of forming grains described in the art, such as agglomeration, stamp, thread, etc. Previous formation processes sometimes contributed to the confusion of the previous abrasive materials as fillers in thermoplastic or reinforcing the matrix. Such processes are, for example, with the selection of the matrix and the corresponding content of the filler is well known in the art. A particularly preferred method of achieving compliance with the effective range of the roughness of the particles in the abrasive foaming raw material itself or abrasive material dispersed in the matrix and transform the resulting foam abrasive particles with high efficiency. The process of foaming and foam structure, typically reach due to the enlargement process gas, for example, or by introducing a gas or solvent in the abrasive precursor and allowing expansion by pressure and/or temperature increase, for example, the process of extrusion foaming, or more traditionally the gas collected in the field, followed by curing of the abrasive precursor, for example, the foaming process of the polyurethane. Alternatively, the structure of the foam also mouthbut achieved using the process of emulsification, and then stages of curing and drying.

In a highly preferred implementation of this application in order to achieve descriptors geometrical shape of the abrasive cleaning particles (e.g., roughness, roundness and/or strength) abrasive cleaning particles produced from a foamed polymer material, which in turn the abrasive particles preferably by grinding or milling, as described in this application next.

The applicant has found that good cleaning efficiency will be achieved with abrasive particles, which were made of foam with a density of more than 100 kg/m³and even up to 500 kg/m³. However, the applicant has unexpectedly found that a much better cleaning effect can be achieved with foam density below 100 kg/m³, more preferably from 5 kg/m³up to 100 kg/m³and most preferably from 25 kg/m³up to 50 kg/m³.

Similarly, the applicant has found that good cleaning performance can be achieved with abrasive particles, which were made of foam, with the structures of closed cells, however, the applicant has unexpectedly found that a much better cleaning effect can be achieved with the foam structure of open cells.

Similarly, the applicant has found that good cleaning effect can be achieved with abrasive what astitsy, which were made of foam with a mesh size of from 20 micrometers to 2000 micrometers. However, the applicant has unexpectedly found that a much better cleaning effect can be achieved with foam with a cell size of 100 to 1000 micrometers, more preferably from 200 to 500 micrometers, and most preferably from 300 to 450 micrometers. The cell size of the foam can be measured, for example, according to the Protocol described in ASTM D3576.

In a preferred implementation, in order to promote the transformation of the foam part, the foam preferably has sufficient fragility, for example, the tension, the foam has a low tendency to warp, but rather breaks up into particles.

Effective particles are then obtained through the accurate grinding of the structure of the foam to the target size and shape. Thus, for example, when large desired particle size is desirable foam with large cell size and Vice versa. Additionally, in order to maintain the optimal form of particles in the transformation of the structure of the foam in the particle, it is recommended that the target particle size is not excessively below the cell size of the foam. Typically, the target particle size not lower than approximately half the cell size of the foam.

In order to promote the transformation of the foam particles, the foam preferably has sufficient fragility, for example, the tension, the foam has the low tendency to warp and subject to destruction. Foam, which is used in the present invention, is preferably not detectable phase transition (for example, the glass transition temperature or melting or transition temperature significantly higher than the temperature of use. Preferably, the transition temperature at least 20°C, preferably at 40°C higher than the temperature of use.

One of the acceptable ways of turning the foam in the abrasive cleaning particles in this application is shredding or grinding the foam. Other suitable methods include the use of tools to erosion, such as high-speed erosive wheel bag, where on the surface of the wheel engraved pattern, or it is covered with abrasive grinding paper, etc. to help ensure that the foam formed abrasive cleaning particles in a given application.

Alternatively, and in a highly preferred implementation in this application, the foam can be converted into particles in several stages. First, the volume of foam can be broken down into pieces of a few centimeters by grinding or cutting manually or by mechanical means, such as extender lumps, for example, the model 2036 S Howes, Inc. of Silver Creek, NY.

Preferably the abrasive cleaning particles obtained by operations of crushing or grinding, are the battle single particles, not having a cellular structure.

By the way, it has been unexpectedly found that the abrasive cleaning particles according to the present invention show a good feature clean even at relatively low levels, such as preferably from 0.1% to 20%, preferably from 0.3% to 10%, more preferably from 0.5% to 5%, even more preferably from 1.0% to 3% by weight of the total composition of said abrasive cleaning particles.

In the preferred implementation of the abrasive particles are obtained from the foam due to the transformation (preferably by grinding or milling) foam abrasive particles. More preferably the abrasive particles are obtained from a foamed polymer material where the polymer material is chosen from the group consisting of polyethylene, polypropylene, PVC, polycarbonate, melamine, urea, polyurethane, polyacrylate, polystyrene, phenol-aldehyde resins, polyesters, polyamide and mixtures thereof. Even more preferably the abrasive particles are obtained from foamed polymeric material selected from the group consisting of polyurethane, polyester, polyacrylate, polystyrene and mixtures thereof. Most preferably the abrasive particles are obtained from rigid polyurethane foam obtained from a diisocyanate (for example, Lupranate M200R or Lupranate M20S) and diol (Lupranol 3423).

The particles used in the present from which reenie, can be white, transparent or dyed using suitable dyes and/or pigments. Additionally acceptable color stabilizing agents can be used to stabilize the desired color.

The hardness of the abrasive particles

The preferred abrasive cleaning particles suitable for use in this application are strong enough to provide the characteristics of a good cleaning/deep cleaning, at the same time providing a good safety profile of the surface.

The hardness of the abrasive particles into the foam, can be changed by changing the raw materials used to obtain the foam. For example, modification of the hardness of the polyurethane is possible in different ways. For example, without being exhaustive, the choice of diisocyanate and especially the choice of isocyanate with high functionality, for example >2, preferably >to 2.5, most preferably more than 2.7, increases the hardness of the polyurethane. Similarly, the use of low molecular weight polyols, for example, <4000 Mm, preferably <2000 Mm and most preferably less than 1000 Mm also increases the hardness of the polyurethane. Even more important is the balance of diisocyanate/polyol in the reaction mixture, whereas an excess of diisocyanate also increases the hardness of the foam. Another possibility of increasing the hardness of predstavljaet the introduction of low-molecular agent cross-linking. An alternative choice of catalyst will promote the formation of urea linkages, which is an additional method of increasing the hardness of the foam.

The method of testing the hardness Vickers

The Vickers hardness HV was measured at 23°C in accordance with standard methods ISO 14577-1, ISO 14577-2, ISO 14577-3. The Vickers hardness is measured in a solid block of raw material at least 2 mm in thickness. Measurement of microgranule hardness Vickers is carried out using a micro-hardness tester (dost), the production of CSM Instruments SA, Peseux, Switzerland.

In accordance with the instructions of ISO 14577, the test surface should be flat and smooth, with a roughness value (Ra) of less than 5% of the maximum penetration depth of the indenter. For maximum depth of 200 μm, this corresponds to an Ra value of less than 10 μm. In accordance with ISO 14577, such surface can be obtained by any suitable means, which may include cutting a block of test material new sharp microtome or a scalpel blade, grinding, polishing or casting molten material on a smooth form of casting that is allows you to thoroughly cure before testing.

Acceptable General installation parameters for microhardness tester (MNT) are as follows:

Control mode: moving, continuous

Maximum displacement: 200 µm

Approach speeds: 20 nm/s

The definition of the zero point: contact

The retention period for measuring the temperature drift contact: 60

Time of application of the forces: 30pm

The frequency of writing data: at least every second

Retention time at maximum force: 30

Forced removal: 30

Shape/Material of the indenter tip: the shape of a pyramid Vickers/Diamond tip.

The cleaning efficiency

The way to test the effectiveness of cleaning:

Tile (usually glossy, white, KERS is ical 24 cm × 4 cm) cover 0.3 g typical fatty soap foam is mainly based on calcium stearate and commercially available artificial contamination of the body (applied to the tile by means of a spray). Contaminated tiles are then dried in an oven at a temperature of 140°C for 10-45 minutes, preferably 40 minutes, and then sostarivayut from 2 to 12 hours at room temperature (approximately 20°C) with adjustable humidity environment (60-85% relative humidity, preferably 75% relative humidity). Then polluted tiles cleaned using 5 ml of the composition in accordance with the present invention, which is poured directly onto pre-moistened cellulose sponge Spontex®. The sponge is then mounted on the scraper test tool wet abrasion (for example, from Sheen Instruments Ltd. Kingston, England) with the side coated with the composition of the particles directed toward the tile. The abrasion tester can be configured to provide pressure (for example, 600 g) and move the sponge on the test surface with a certain step length (for example, 30 cm), at a given speed (for example, 37 steps per minute). The ability of the composition to remove the oily soap foam is measured through the number of steps needed to perfectly clean the surface, as determined by visual assessment. The smaller the number of steps, the greater the ability of the composition to clear fatty lather.

Data cleaning below achieved with 1% of abrasive particles in the cleaner (3.5% of non-ionic surfactants C12EO5). Abrasive of sistematica used to obtain sample data cleaning, received for polyurethane foam, having a value of Vickers hardness of 7 kg/mm². Abrasive cleaning particles produced from rigid polyurethane foam by crushing the foam in the abrasive cleaning particles.

Examples 9-10 are comparative examples in which the abrasive cleaning particles are outside of the scope of the present invention.

Safety surface

The method of surface damage:

For measurement of surface damage caused by test particles,a mixture of 0.2 g of the abrasive particles should be tested with 4 g of an aqueous lotion NEODOL C9-11 EO8 surfactants (Shell Chemicals) (3% surfactant by weight). Moisten a new kitchen cellulose sponge (for example, Spontex®) a size of 4 cm × 8.5 cm (4.5 cm thick) 24 ml of distilled or deionized water, and then fill through a uniform distribution of surfactant and a mixture of particles of 4 cm × 8.5 cm side of the sponge. The sponge is then mounted on the scraper test tool wet abrasion (for example, from Sheen Sheen Instruments Ltd, Kingston, England) with a side of coated particles and surface-active agent, addressed to the test surface. Test the surface for use must be a new sheet uncolored, transparent, pristine poly(methylmethacrylate) (also known as emission spectra obtained for pure, Plexiglass, Perspex, Lucite), with a value of Vickers hardness HV 25 kg/sq. mm (+/-2) as measured using standard test method ISO 14577). The abrasion tester must be configured to provide 600 g pressure and move the sponge on the test surface with a step length of 30 cm, with a speed of 37 steps per minute. The scraper tester wet abrasion should be allowed to run 1000 steps (i.e. 1000 in one direction of displacement), then the sponge re-fill additional 0.2 g of abrasives and 4 g of lotion surfactants. Additional water should not be applied when re-filling sponge. The sponge should be popcorn is filled with so every 1000 steps, for ten consecutive fillings (e.g., 10,000 steps in total on the test surface). Assessment of damage to the test surface is performed after 10,000 steps. The sponge should not be replaced during the test, unless it is damaged, such as torn or broken. In this case, a new sponge should be damp, be filled and installed in accordance with the instructions for the original sponge in order to pass the test.

To assess surface damage on poly(methyl methacrylate) test surface, the visual classification is carried out on the following 5-level scale damage to the surface: 0 = I don't see scratches, 1 = I think I see scratches, 2 = I can definitely see small scratches, 3 = I see a lot of scratches, 4 = I see much damage. The visual scale of the damage is the average of the assessments of the 5 independent valuers.

Additionally, damage to the surface on poly(methyl methacrylate) test surface was also evaluated by measuring the surface roughness worn sponge, using a roughness tester, for example, TR 200 (PortableTesters.com LLC). Several parameters of profile roughness measure, including the average maximum height (Rz), overall height roughness (Rt), the maximum peak height (Rp), the maximum depth plane (Rv), Regni step irregularities (RSm), and asymmetry (Rsk).
