TECHNICAL FIELD
The present invention relates to liquid compositions for cleaning and / or washing a variety of animate and inanimate surfaces, including hard surfaces in or around the home, tableware surfaces, hard or soft tissue surfaces of the cavity buccal, such as teeth, gums, tongue and buccal surfaces, human and animal skin, surfaces of vehicles and automobiles, etc. More specifically, the present invention relates to abrasive liquid compositions comprising particles suitable for cleaning and / or washing.
BACKGROUND OF THE INVENTION
Abrasive compositions, such as particulate or liquid compositions (including gel or paste-like compositions) containing abrasive components are well known in the industry. Said compositions are used for cleaning and / or washing a variety of surfaces, especially those surfaces that tend to get dirty with stains and dirt that are difficult to remove.
Among the currently known abrasive compositions, the most popular are based on abrasive particles with shapes that vary ^<sup>ST</sup>'X<sup>OR</sup>7? ** IXICANO Say THE industrial PROPERTY
<img file="MX337625B_D0012.tif" />
from spherical to irregular. The most common abrasive particles are inorganic, such as carbonate salt, clay, silica, silicate, shale ash, perlite and quartz sand, or organic polymeric microspheres such as polypropylene, PVC, melamine, urea, polyacrylate, and derivatives, which are They provide in the form of a liquid composition with a creamy consistency and abrasive particles suspended in it.
The surface safety profile of such currently known abrasive compositions is inadequate, while compositions with a suitable surface safety profile show poor cleaning performance. Clearly, because they have high hardness abrasive particles, these compositions can damage, that is, scratch, the surfaces on which they have been applied, while, if the amount of hard materials is reduced, the cleaning performance is insufficient. Clearly, the formulator must choose between an adequate cleaning / washing performance 15 that generates significant surface damage, or resign the cleaning / washing performance and maintain an acceptable surface safety profile. Furthermore, such currently known abrasive compositions, at least in certain fields of application (eg, hard surface cleaning) are considered obsolete by consumers.
Therefore, an object of the present invention is to provide a suitable cleaning and / or washing composition for cleaning / washing a variety of surfaces, including inanimate and animated surfaces, such as hard surfaces inside or on
<img file="MX337625B_D0013.tif" />
House surroundings, tableware surfaces, soft tissue surfaces of the oral cavity, such as teeth, gums, tongue and oral surfaces, human and animal skin, etc., where the composition provides cleaning / washing performance satisfactory, while providing an adequate safety profile for the surface.
It has been discovered that the aforementioned objective can be achieved through the composition according to the present invention.
One of the advantages of the compositions according to the present invention is that they can be used to clean / wash animated and inanimate surfaces composed of various materials, such as glazed or unglazed ceramic tiles, enamel, stainless steel, Inox®, Formica®, vinyl, non-waxed vinyl, linoleum, melamine, glass, plastic, painted surfaces, human and animal skin, hair, surface of hard and soft tissues of the oral cavity, such as teeth, gums, tongue and buccal surfaces, and the like.
Another advantage of the present invention is that, in the compositions of the present invention, the particles can be formulated at greatly reduced levels and still provide the aforementioned benefits. Clearly, in general for other technologies, high levels of abrasive particles are required to achieve adequate cleaning / washing performance, leading to high formulation and processing costs, incompatibility with many packages, e.g. eg, atomizer or compressible container, ergonomics of use of low incidence, profiles of <sup>4</sup> IMPIf

Abrasive cleaning particles
The liquid cleaning and / or washing composition of the present invention comprises abrasive cleaning particles that are selected or synthesized to have effective forms, e.g. eg; defined by rigor and adequate hardness.
In a preferred embodiment, the abrasive cleaning particles are preferably non-rolling. Furthermore, in a preferred embodiment, the abrasive cleaning particles are preferably angular.
<img file="MX337625B_D0017.tif" />
MEXICAN INSTITUTE OF PROPERTY
INDUSTRIAL
<img file="MX337625B_D0018.tif" />
The Applicant has noted that the angular, non-rolling abrasive cleaning particles allow for adequate soil removal and reduce surface damage. Clearly, the Applicant has observed that very specific particle forms, e.g. For example, defined by circularity to promote efficient sliding of abrasive particles compared to typical abrasive particles, where rotational motion is promoted in a certain way and is less effective since it displaces dirt from the surface. The circularity to meet the criteria to promote efficient particle slippage is in the range of 0.1 to 0.45.
The shape of the abrasive cleaning particle can be defined in various ways. The present invention defines the shape of the cleaning particle in a particle shape, reflecting the geometric proportions of a particle and, more pragmatically, of the particle population. There are very recent analytical techniques that allow accurate simultaneous measurement of particle shapes based on a large number of particles, typically greater than 10,000 particles (preferably greater than 100,000). This allows precise adjustment and / or selection of the shape of the average particle population with differentiated performance. These particle shape measurement analyzes are performed with the Occhio Nano 500 particle characterization instrument and the supplied Callistro software, version 25 (Occhio sa Liege, Belgium). This instrument is used to prepare, disperse, portray, and analyze particle samples according to the manufacturer's instructions and
<img file="MX337625B_D0019.tif" />
following instrument setup selections: 613000 ^ 500330 ^ = 180, vacuum time = 5000 ms, settling time = 5000 ms, auto threshold, number of particles counted / analysis = 8000 to 500,000, minimum number of duplications / sample = 3, 1x / 1.5x lens configuration.
The abrasive cleaning particles of the present invention are defined by the quantitative description of a form. In the quantitative description, the shape descriptor is understood as the numbers that are
I can calculate from the images of the particles or the physical properties of the particles by mathematical or numerical operations. Although the shape of the particle can be defined in three dimensions with a specific analytical technique, the applicant has observed that the characterization of the shape of the particles in two dimensions is the most relevant and is related to the abrasive performance of the cleaning particles. . During the particle shape analysis protocol, the particles are oriented toward the surface, by gravity deposition, in a manner similar to the expected orientation of the particles during the cleaning process. Therefore, the objective of the present invention considers the characterization of the two-dimensional shape of a particle / particle population as defined by the projection of its shape on the surface on which the particle / particle population is deposited.
In a preferred embodiment, the abrasive cleaning particles have an average circle equivalent diameter (ECD) of 10 pm to
<img file="MX337625B_D0020.tif" />
1000 μιτι, preferably, from 50 pm to 500 pm, most preferably, from 100 pm to 350 pm and, most preferably, from 150 to 250 pm.
Clearly, the Applicant has observed that the size of the abrasive particles can be critical to achieving efficient cleaning performance, while an excessively abrasive population with small particle sizes, e.g. eg typically less than 10microns have a polishing action vs. cleaning, despite containing a high amount of particles per particle load in the cleaner inherent in the small particle size. In contrast, the abrasive population with an excessively high particle size, e.g. Eg, greater than 1000 microns, does not provide optimal cleaning efficiency, as the number of particles per particle load in the cleaner is inherently significantly decreased by large particle size. Furthermore, excessively small particle size is not recommended in the cleaner or for cleaning tasks since, in practice, the numerous small particles are frequently difficult to remove from the different surface topologies, which implies a Excessive strain on the user, unless you leave the surface with visible particulate residue. On the other hand, excessively large particles are very easy to detect with the naked eye or generate an unpleasant experience to the touch while using or handling the cleaner. Therefore, applicant defines in the present description a

INDUSTRIAL optimal particle size range that provides both excellent cleaning performance and user experience.
Abrasive particles have a size defined by the diameter equivalent to the area (ISO 9276-6; 2008 (E), section 7) also called circle equivalent diameter (ECD) (ASTM F1877-05, section 11.3.2). The mean ECD of the particle population is calculated as the average of the respective ECD of each particle in a particle population of at least 10,000 particles, preferably, greater than 50,000 particles, more preferably, greater than 100,000 particles, after excluding from Measurement and calculation data for particles with an area equivalent diameter (ECD) of less than 10 microns. Average data is obtained from measurements based on volume vs. quantity-based measurements.
In a preferred example, the size of the abrasive cleaning particles used in the present invention is modified during use, especially when undergoing a significant size reduction. Therefore, the particle remains visible or noticeable to the touch in the liquid composition and at the beginning of the use process to provide effective cleaning. As the cleaning process progresses, the abrasive particles disperse or break down into smaller particles and become invisible to the human eye or imperceptible to the touch.
In the present invention, the shape descriptors are calculations of the geometric descriptors / shape factors. Geometric shape factors are the relationships between two different geometric properties. Said

ίproperties are usually a measure of the proportions of the image of the entire particle or a measure of the proportions of an ideal geometric body that wraps the particle or forms a wrap around the particle. These results are macroform descriptors similar to the aspect ratio; however, the Applicant has observed that mesoform descriptors (a specific subclass of macroform descriptors) are especially critical to cleaning efficiency and surface safety of abrasive cleaning particles, while the parameters of More typical forms, such as the aspect ratio, are insufficient. These mesoform descriptors describe how different a particle is compared to an ideal geometric shape, especially how different it is compared to a sphere and, on the other hand, help define its non-rolling capacity, e.g. eg, slip, effective cleaning movement pattern. The abrasive cleaning particles of the present invention are different from typical spherical or sphere-like abrasive shapes, e.g. eg granular.
The abrasive cleaning particles of the present invention are not spherical.
The non-spherical particles in the present invention preferably have angular edges and each particle has at least one edge or concave curvature surface. Most preferably, the non-spherical particles in the present invention have numerous angular edges and each particle has at least one edge or concave curvature surface. The angular edges of the non-spherical particles are defined because the edge has

Roughness
Roughness is a quantitative description of shape by two-dimensional image analysis, and is measured in accordance with ISO 9276-6: 2008 (E), section 8.2, implemented through the Occhio Nano 500 particle characterization instrument and its software. incorporated, Callistro, version 25 (Occhio sa Liege, Belgium). Roughness defines 2D measurements, the equivalent useful surface area outside the surface area of the particle nucleus, and its value can vary from 0 to 1, where a roughness value of 0 describes a particle with no available useful mass at the periphery of the nucleus of the particles. Roughness is also sometimes referred to as "irregularity," and is a quantitative description, and a mesoform descriptor is available, eg. eg; on the Occhio Nano 500 instrument.
Roughness is useful in abrasive particles because the non-spherical particles in the present invention preferably have a significant mass of material, available at the periphery of their core, as useful abrasives. The peripheral mass is useful for cleaning performance and also to prevent the particle from rolling.
Roughness involves defining in two-dimensional measurements the equivalent useful surface area outside the surface area of the core of

MEXICAN INSTITUTE OF PROPERTY
INDUSTRIAL particles ranging from 0 to 1, where a roughness T'of ^ O describes a particle with no useful mass available at the periphery of the mass of the particle nucleus. The roughness is calculated as follows:
<sup>5</sup> Rgy = (AA (Oy) / A
Where A is the area of the particle and A (Oy) is the surface area of what is considered the “core of the particle”. Α-Α (Ογ) represents the “useful area at the periphery of the particle” and the roughness represents the fraction of that useful area compared to the total area of the particle. Ογ is called the adjustable tolerance factor and is typically set to 0.8, so the definition of roughness is Rgy = (AA (0.8) / A. In order to calculate A (0.8), the maximum number of disks within the particle boundary is inscribed at each point on the edge of the particle. The size, p. For example, the area of the inscribed discs is defined by the diameter of the discs, while the diameter value varies between 0.8xDmax (maximum diameter) and Dmax (where Dmax is the diameter value of the largest disc inscribed in the particle). The area of the nucleus of particle A (0.8) is defined by the area corresponding to the projection of all the inscribed disks.

Such processes, p. Eg, which include selecting a die and a respective filler load, are well known in the industry. A particularly preferred process for obtaining particles with an effective roughness range consists of foaming the abrasive raw material itself or the abrasive material dispersed in a matrix, and reducing the foam obtained to abrasive particles with improved efficiency. Foaming processes and foam structure are typically accomplished by a gas expansion process, e.g. eg, either by injecting gas or solvent into the abrasive precursor and the consequent expansion by pressure drop and / or temperature rise, e. Eg: extrusion foaming process or, more suitably, with gas generated in situ followed by hardening of the abrasive precursor, eg. eg, polyurethane foaming process. As an alternative, the foam structures can also be achieved by an emulsion process, followed by a hardening and drying step.

Furthermore, the Applicant has observed that a suitable cleaning effect can be achieved with abrasive particles that have been made from foams with a cell size ranging from 20 microns to 2000 micrometers. However, the Applicant has surprisingly discovered that a significantly improved cleaning effect can be achieved with the foam having a cell size of 100 to 1000 microns, more preferably 200 to 500 microns, and most preferably , from 300 to 450 micrometers.

INSTITUTO MACANO 0 £ LA PROz'SOAD industrial foam cell size can be measured, for example, using the protocol described in ASTM D3576.
In a preferred embodiment, in order to promote the reduction of the foam to particles, the foam preferably has sufficient brittleness, e. eg; under pressure, the foam has a reduced tendency to deformation but also breaks down into particles.
Effective particles are subsequently produced by grinding the foam structure to the desired size and shape. Therefore, for example, when it is desired to obtain a large particle size of 10, foam with a large cell size is recommended, and vice versa. Furthermore, in order to preserve the optimal shape of the particle by reducing the structure of the foam to particles, it is recommended that the particle size to be obtained is not excessively smaller than the cell size dimension of the foam. Typically, the target particle size # 15 is less than about half the cell size of the foam.
To promote the reduction of the foam to particles, the foam preferably has sufficient brittleness, eg. For example: under pressure, the foam has a reduced tendency to deformation and it is possible that it will fracture. The foam used in the present invention preferably has an inconspicuous phase transition (eg, glass transition or melting temperature) or a phase transition temperature significantly higher than the use temperature.

phase transition temperature is at least 20 ° afferently, ° C, above the use temperature. ·
A suitable method of reducing foam to abrasive cleaning particles in the present invention is to grind or grind the foam.
Another suitable means includes the use of erosion tools, such as a high speed erosion wheel with a dust collector, where the surface of the wheel is engraved with a pattern or is coated with abrasive sandpaper or the like, to causing the foam to form the abrasive cleaning particles of the present invention.
As an alternative and in a highly preferred embodiment of the present invention, the foam can be reduced to particles in several stages. First, the foam dough can be divided into pieces of a few centimeters by cutting or chopping it manually, or by using a mechanical tool, such as a dough grinder, e.g. eg, Model 2036 from S Howes, Inc. of Silver Creek, New York.

In a preferred embodiment, the abrasive particles are obtained from a foam by reducing (preferably by grinding or grinding) the foam to abrasive particles. More preferably, the abrasive particles are obtained from foamed polymeric material, characterized in that the polymeric material is selected from the group consisting of polyethylene, polypropylene, PVC, polycarbonate, melamine, urea, polyurethane, polyacrylate, polystyrene, phenols, polyesters, polyamide and mixtures thereof. Still more preferably, the abrasive particles are obtained from the foamed polymeric material selected from the group consisting of polyurethane, polyester, polyacrylate, polystyrene, and mixtures thereof. Most preferably, the abrasive particles are obtained from a rigid polyurethane foam, composed of diisocyanate (eg Lupranate M200R or Lupranate M20S) and diol (Lupranol 3423).
The particles used in the present invention can be white, transparent, or colored through the use of suitable dyes and / or pigments. Furthermore, suitable color stabilizing agents can be used to stabilize the desired color.
Hardness of abrasive particles:
The preferred and suitable abrasive cleaning particles for use in the present invention are hard enough to provide adequate cleaning / washing performance at the same time, providing an adequate surface safety profile.
The hardness of the abrasive particles obtained from foam by reduction can be modified by changing the raw material used to prepare the foam. For example, it is possible to modify the hardness of the polyurethane foam in various ways. For example, by way of example, the selection of diisocyanate and, particularly, the selection of highly functional isocyanate, e. eg:> 2, preferably »2.5, most preferably more than 2.7, increases the hardness of the polyurethane. Similarly, the use of low molecular weight polyols, e.g. eg: <4000 Mw, preferably <2000 Mw and, most preferably, less than 1000 Mw, also increases the hardness of the polyurethane. Even more important is the balance of diisocyanate / polyols in the reaction mixture, because excess diisocyanate also increases the hardness of the foam. Another possibility to increase hardness is to introduce a low molecular weight crosslinking agent. As an alternative, the selection of the catalyst will allow the formation of a urea bond, which represents another method to increase the hardness of the foam.
The abrasive cleaning particles in the present invention have a hardness of 3 to 50 kg / mm<sup>2</sup>preferably 4 to 25 kg / mm<sup>2</sup> and, most preferably, from 5 to 15 kg / mm<sup>2</sup> in the Vickers hardness test (HV). Vickers hardness test method:

Vickers is calculated from a solid block of raw material at least 2mm thick. The measurement of Vickers hardness by microindentation is carried out using the Micro-Hardness Tester MHT, manufactured by CSM Instruments SA, Peseux, Switzerland.
According to the instructions included in ISO 14577, the test surface must be flat and smooth, with a roughness value (Ra) less than 5% of the maximum penetration depth of the indenter. For a maximum depth of 200 pm, this equates to a Ra value of less than 10 pm. According to ISO 14577, such a surface must be prepared by any of the appropriate methods, which may include cutting the block of the test material with a sharp microtome or a scalpel, crushing, polishing or molding the molten material in a mold. flat and smooth cast iron, and allow it to solidify completely before testing.

As an alternative, for the abrasive cleaning particles of the present invention, the hardness can also be expressed in accordance with the MOHS hardness scale. Preferably, the MOHS hardness is between 0.5 and 3.5, most preferably between 1 and 3. The MOHS hardness scale is an internationally recognized scale for measuring the hardness of a compound compared to a compound of known hardness. See Encyclopedia of Chemical Technology, Kirk-Othmer, fourth edition, vol. 1, p. 18, or Lide, DR (ed) CRC Handbook of Chemistry and Physics, edition no. 73, Boca Raton, Fia .: The Rubber Company, 19921993. There are many MOHS test kits available on the market, which contain material with known MOHS hardness. For the measurement and selection of the abrasive material with the selected MOHS hardness, it is recommended to perform the MOHS hardness measurement with amorphous particles, e.g. eg: with spherical or granular shapes of the abrasive material, since the MOHS measurement of the shaped particles will give erroneous results.

<img file="MX337625B_D0059.tif" />
The soiled tiles are then dried in an oven at a temperature of 140 ° C for 10 to 45 minutes, preferably 40 minutes, and then left to rest for 2 to 12 hours at room temperature (approximately 20 ° C) at controlled ambient humidity (60 to
85 % relative humidity (RH), preferably 75% RH). The soiled tiles are then cleaned using 5 ml of the composition of the present invention poured directly onto a previously moistened Spontex® cellulose sponge. The sponge is then placed in a wet abrasion testing instrument (such as the one manufactured by Sheen

The abrasion test instrument must be able to perform 1000 passes (that is, 1000 movements in a single direction); the sponge is then reloaded with an additional 0.2 g of abrasive and 4 g of surfactant lotion. No additional water should be applied when recharging the sponge. The sponge should be recharged in this manner every 1000 passes, for ten consecutive charges (i.e. 10,000 passes total per test surface). Damage assessment on the test surface is performed after completing the 10,000 passes. The sponge should not be replaced during the test unless it is damaged, for example broken or torn. In that case, a new sponge should be moistened, loaded and installed according to the instructions for the original sponge in order to complete the test.

To assess the surface damage err-tmsrsuperfieie-test poly (methyl methacrylate), a visual classification is performed according to the following 5-level surface damage classification scale: 0 = No scratches observed; 1 = There may be scratches; 2 5 Small scratches are clearly visible; 3 = Many scratches are observed; 4 = Significant damage is observed. The visual damage rating is the average of the ratings given by 5 independent classifiers.
In addition, surface damage on the poly (methyl methacrylate) test surface is assessed by measuring the roughness of the sponge-rubbed surface, using a roughness analyzer, such as TR 200 (PortableTesters.com LLC). Various profile roughness parameters are measured, including: average maximum height (Rz); height from peak to total valley (Rt); maximum peak height (Rp); maximum valley depth (Rv); mean separation of irregularities (RSm); and asymmetry (Rsk).

Examples
The following compositions were made with the ingredients shown in the mentioned proportions (weight%). Examples 1 to 43 of the present invention are used to exemplify the present invention, but not necessarily to limit or in any other way define the scope of the present invention.
The abrasive particles used in the following examples were ground from rigid polyurethane foam (controlled foam structure, eg, foam density, cell size, column aspect ratio, and% cell size content) . The polyurethane foam is synthesized from the reaction of a diisocyanate (eg, polymer-based methylene diphenyl diisocyanate) and polyols (eg, polyether-based or polyester-based polyol). Where the diisocyanate is, for example, Lupranate M200R from BASF, and the polyol is, for example, Lupranol 3423 from BASF. The foam was crushed until small particles were obtained and sieved with a

Examples 24 to 27 are done as follows:
Carbopol® is added to the deionized free water of the formulation. All surfactants are added, with the exception of cationic and betaines. If the pH is less than 6, then a neutralizing agent (typically a base, i.e. triethanolamine, sodium hydroxide) is added to adjust the pH to a value greater than 6. If necessary, gentle heat is applied to reduce viscosity and help minimize air entrapment. Betaine and / or cationic surfactants are added. Agents added

conditioners, additional rheology modifiers, pearlizing agents, encapsulated materials, exfoliants, preservatives, dyes, fragrances, abrasive particles, and other desirable ingredients. Finally, if desired, the pH is lowered with an acid (i.e. citric acid), and the viscosity is increased by adding sodium chloride.
