These inclusions suspended they appear desirably as discrete visible particles suspended within the composition, particularly by a consumer who has a normal vision "20/20". It has to understand however that not all particulate materials present in the composition of the invention need to be visibly distinguishable since a portion of the particulate materials it may be smaller than the visible threshold of normal vision that Has the consumer. It is required however that at least one portion of the particulate materials present in the composition of the invention be visibly distinguishable as particles discreet

Desirably, particulate materials Alginate based are supplied so as to have a size of average particle in the range of about 50 µm up to about 1000 µm, preferably in the range of about 350 µm to about 700 µm, more preferably in the range of about 550 µm to around 650 µm, and especially preferable in the range from about 575 µm to about 625 mm. So Desirable, the average particle size of these materials particulates represent at least 85% of the particles, plus preferably at least 90%, even more preferably at least 92%, and more preferably at least 95% of the particles present are within a specified interval. Suspended inclusions present in the compositions of the invention are based on alginates although other discrete particulate materials visibly distinguishable can also be used, or instead of alginate based materials. However inclusions Preferred suspended are based on alginates.

The alginate-based particulate materials used for the inclusions suspended in the compositions of the invention may be formed from an alginate or alginic acid salts such as potassium alginate, calcium alginate or sodium alginate salts, and can advantageously be conveniently collected at starting from naturally occurring algae especially from the Laminaria species in which the sodium alginate form predominates. The alginates typically consist of sequences of α-L-guluronic acid and β-D-mannuronic acid that can be present in the alginate in various variable ratios. The term "balls" conveniently describes the geometry of alginate-based particulate materials such as when they are formed from an aqueous suspension containing an alginate such as sodium alginate with one or more additional constituents and then expelled to form individual particles or drops. , the homogeneous aqueous suspension can form generally spherical particles, hence the term "balls." Of course, other processes for the formation of suspended inclusions based on alginate are also contemplated as being useful together with the present invention such as processes in which the alginate optionally containing one or more additional constituents is disintegrated by other methods, such as ground, grated or other techniques known in the art. In such cases, suspended inclusions based on disintegrated alginate do not necessarily form generally spherical particles but can form individual particles of irregular geometry. In such a case the largest dimension of such individual particles of irregular geometry are used as the basis for determining the average particle size of the suspension. The alginate based particulate materials may contain from about 0.5% by weight to 100% by weight of an alginate or alginate salt, although quite often the amount of alginate in the alginate based particulate materials is much smaller, generally from about 0.5% by weight to about 10% by weight, more preferably from about 0.5% by weight to about 5% by weight. Such alginate based on particulate materials may conveniently be referred to as "alginate balls". Such alginate balls may be formed by a variety of processes known in the art that include those described in the background section of WO-A-9702125 by Thomas et al., As well as in US Pat. No. 6,467. 699 B1, the content of which is incorporated by reference. Alternatively, such alginate-based particulate materials can be purchased commercially from various suppliers, including geniaLab BioTechnologie (Braunschwig, Germany). As indicated the composition of the alginate-based particulate materials may include only a small portion of an alginate or alginate salt, and may include one or more additional non-alginate materials especially one or more inorganic materials such as titanium dioxide which improves the opacity, and therefore the visibility of the balls, as well as one or more coloring agents such as pigments such as ultramarine blue, said coloring agents that also improve the aesthetic appearance of the balls. Other additional non-alginate materials not mentioned herein may also be included in the composition of the alginate-based particulate materials. The alginate-based particulate materials may be composed of a greater proportion of water that is coupled within the structure of discrete alginate-based particulate materials, and due to the highly porous character of the alginates, when they are in an 80% aqueous composition. weight, and usually 90% by weight or even greater the mass of discrete alginate based particulate materials may be water with the remaining balance being up to 100% by weight alginate or alginate salt, and one or more additional non-alginate materials. Suitably such alginate based particulate materials may be prepared, stored and sold as a suspension of discrete alginate based particulate materials in a water based carrier composition that may contain a minor amount of one or more additional additives such as one or more salts especially Chloride salts such as calcium chloride, as well as a preservative to inhibit the growth of undesirable microorganisms in the suspension containing particulate materials based on discrete alginates. A preferred commercially available alginate based particulate material comprises from about 0.5% by weight to about 5% by weight of a calcium alginate, a pigment present in an amount up to about 0.01% by weight, from about 0.1% by weight up to about 5% by weight of TiO2 and the remaining balance of the mass of the alginate-based particulate material comprised in a 2% calcium chloride solution in water that may also contain a smaller amount , approximately 2% calcium chloride. Such alginate-based particulate material may be separated from a water-based vehicle composition by means of a fine sieve or other means to decant the composition of a water-based vehicle from alginate-based particulate materials.

Since the compositions are mostly of aqueous nature, and comprise for the balance of the composition water to provide up to 100% by weight of the compositions of the invention Water may be running water, but it is preferred distilled and more preferably deionized water. If water is water current, it is preferred that it be substantially free of any undesirable impurity such as organic or inorganic substances, especially mineral salts that are present in hard waters that they can thus undesirably interfere with the operation of the constituents present in the aqueous compositions according to the invention. The compositions of the invention provide certain technical benefits when used on hard surfaces, particularly: satisfactory removal of water stains hard, satisfactory removal of soap patina stains, and satisfactory disinfection or sanitization of hard surfaces. In preferred embodiments, the compositions are easily pumped using a handy trigger spray device that is Desirably provided as a product ready for use in a container package comprising a spray apparatus pump with manually operable trigger or non-reservoir pressurized or bottle to contain the compositions of the invention. In use, the consumer generally applies an effective amount of the composition and moments later, clean the treated area with a suede, towel, brush or sponge, usually a paper towel disposable or sponge. In certain applications, however, especially where undesirable stain deposits are hard, the composition according to the invention can be left in stained areas until the stain deposits have softened effectively after which they can be cleaned, washed or otherwise removed. For particularly hard deposits of Such undesirable stains, multiple applications can be used.

A particularly advantageous feature of the compositions of the invention is that since the inclusions suspended are visibly discrete and visibly distinguishable to the consumer, these same inclusions are visible to the consumer on hard surfaces for which the compositions of the invention have been applied This allows a ready visual inspection of the hard surface coating by compositions of the invention immediately after application of the composition by a consumer Such a thing provides not only an attribute appeal to commercial products based on such compositions it also provides a visual indicator to the consumer of deep coverage and contact with hard surfaces. This visual indicator provides an important means by which the consumer can visually inspect a surface, particularly a surface on which the presence is suspected of undesirable microorganisms, to ensure that the deep coverage and contact with said hard surface is carried out. As is known, the physical contact between the composition of the invention and unwanted microorganisms is required for the Compositions of the invention provide a disinfectant effect.

An important technical feature lies in the rheology of the compositions of the invention. The compositions can be described as being rheopractic at cutting speeds inferior, and especially after remaining in a quiescent state, but they are thixotropic at higher cutting speeds. Such Dual properties are very advantageous, as when the compositions they are at rest in a container, for example, after staying in rest, their rheopic behaviors provide suspension stable of the inclusions described here. When desired administer the compositions from a container especially to through a pump sprayer device with operable trigger manually, the thixotropic characteristics of the compositions allow its administration through the nozzle of such apparatus of pump spraying An example of spray apparatus of manually operated trigger pump, such as a "Specialty Trigger Pump Spray / Off "(ex. Owens-Illinois Corp.). Ideally, after being administered from the apparatus pump sprays on a surface, especially a inclined surface, the compositions return to a state Quiescent and show once again a rheopic behavior. Additionally, since at least some of the inclusions Suspended are supplied from the composition and in the surface, these inclusions are present on the surface and they provide a useful indicator as well as a coverage of the composition sprayed on the surface.

Alternatively in certain embodiments Preferred compositions of the invention may also be provided in a conventional aerosol, and a propellant added to the constituents forming the composition. However the last Use of the compositions of the invention in an aerosol dispenser is unlikely to be adopted for practical use since Current conventional aerosol dispensers are typically metal boats that do not allow the consumer to easily enjoy of the appearance of discrete particulate materials so Visibly visible distinguishable, such as suspended inclusions when the compositions are in a quiescent state. But nevertheless, the use of the compositions provided in aerosol cans provides the benefit of pressurized administration to the composition, and the composition applied to a hard surface presents discrete particulate materials visibly visibly distinguishable on the treated surface. But nevertheless, the use of a pump spraying device with trigger operable manually with the compositions of the invention is normally preferred.

The compositions of the invention are provided of desirable way as a ready-to-use product that can be applied directly to a hard surface. As an example, hard surfaces suitable for coating with the polymer include surfaces composed of refractory materials such as frosted or non-frosted tiles, bricks, porcelain, frosted ceramics, vitreous ceramics such as Chinese ceramics; glass, metals, plastics, for example, polyester, vinyl, fiber glass, Formica®, Corian®; and other hard surfaces known in the industry.

The order of addition it is not normally critical but preferably, under agitation constant, a constituent of water is added first thickener, then stirring is allowed to continue until the thickening constituent is homogeneously distributed in the Water. However, a homogenizer or other is preferable. raised cutting mixing device to ensure mixing uniform of the thickener constituent in the compositions shown here. Subsequently the non-ionic surfactant is added, then the organic solvent if present, then the anionic surfactant followed by the remaining constituents, including an optional constituent. From there, the Suspended inclusions are introduced, desirably as a aqueous suspension containing alginate based inclusions in an aqueous vehicle, and finally the remaining amount of water necessary to provide 100% by weight of the composition. While the process can be implemented at temperature ambient (approx. 20 ° C) it may be advantageous to heat the water load initial to an elevated temperature, for example, even in excess of 90 ° C to facilitate the incorporation of one or more of the constituents, particularly thickener constituents in the Water.

Sprachability Assessment

An amount of a sample composition was placed inside a non-pressurized bottle to which adapted a spray device with trigger "Specialty Trigger Pump Spray / Off "(ex. Owens-illinois Corp.). A vertical glass panel was used with the device to evaluate the spray characteristics of a Sample composition. At variable distances as small as 10 cm (4 inches) up to as long as 60 cm (24 inches), one composition was dispensed from the spray device with trigger that was held perpendicularly to the panel vertical glass The supply of the composition from the trigger spray device, and features Humidifiers of the composition were observed and evaluated. For to be considered "fit" a composition needs to be dispensed in a generally uniform spray from the device trigger spray within the range of 10-60 cm (4-24 inches), and especially about 45 cm (18 inches) from the vertical panel of glass, and even moisten the surface in general and not form a preponderance of balls or drops that are attached to the panel vertical glass without dispersing after contact.

Each of the formulations according to the invention described in Table 1 were considered "eligible" in the spray test described above.

Evaluation of efficacy against soap patina

The effectiveness of the compositions of the invention to remove patina of soap from a hard surface was evaluated according to CSMA Methods DCC-16 (May 1995) titled "Guidelines for evaluating the Efficacy of Bathroom Cleaners- Part 2: Scrubber Test for Measuring the Removal of Lime Soap ". This essay is generally described as follows:

First, a "mother" land is made, based in the following formulation:

Earth "mother" % Weight / weight Bar of soap 3.90 Shampoo 0.35 clay 0.06 Tallow artificial 0.15 Water hard 95.54

The mother earth was produced according to following stages: First, the bar of soap was cut in Thin pieces in a beaker. Then the constituents remaining were added in the order given above and agitated with a three blade propeller mixer. Then the beaker content was heated until 45-50 ° C and mixed until a suspension was achieved Soft, lump free. This normally required about two hours with moderate agitation. Subsequently, the contents of the beaker were filtered through a Buchner funnel adapted with Whatman No. 1 filter paper or equivalent. Filtering it was then resuspended in clean, deionized water, using the same amount of water used to make the soil, and this was filtered again. The filtrate (refiltered) was dried evenly. overnight at 45 ° C to form a filter cookie. TO from there, the filter cookie was pulverized and was suitable for use immediately, or it can be stored in a sealed container over a period of up to one month.

The test substrates (tiles) were prepared as follows: each tile was washed in depth (using a dishwasher detergent by hand commercially available such as Dove®) and scrubbed using a non-metallic scourer (such as a long-lasting Chore sponge Boy®). The washed tiles were then allowed to dry in an oven at 40.5 ° C overnight, then removed and allowed to cool at room temperature (approx. 20 ° C) before being provided with the standardized "hard water" land test. Has to Note that for each trial, new tiles were used, namely, the tiles were not reused. In preparation for supply the tiles with a quantity of the test soil, a test ground was prepared based on the following formulation:

Test ground % weight / weight Earth "mother" 4.50 Hard water 9.0 Hydrochloric acid (0.1 N) 0.77 acetone 85.73

The soil test was produced according to the following stages: The indicated constituents were introduced in a clean beaker, with acetone being added previously to the water, and the earth "mother" being added the last. The beaker contents were mixed using a standard three blade laboratory mixer until the contents formed a uniform mixture, and the color changed from White to gray. This typically required 20-40 minutes, during which time the glass of precipitates were covered as much as possible to avoid excessive loss of solvent Then an adequate amount of contents of the test soil from the beaker was provided to an airbrush at the same time as the glass of precipitates was agitated to ensure a uniformity of the land. (If more than one trial per day was required, a new amount of test soil was prepared daily and used for the test of the day).

The earth was applied to a number of tiles clean, dry in rows and columns in preparation to deposit the soil sample. The airbrush was operated at 6.9 KPa (40 psi) and the test ground was pulverized to provide an amount of visually uniform ground on the tiles. (One remained uniform ground suspension during application by means of a continuous airbrush movement and / or earth shaking of test on the airbrush.) In this way, approximately 0.10 g-0.15 g of test soil were applied by tile.

The tiles were then allowed to dry air for about 30 minutes, during which time the Laboratory heating plate was preheated until approximately 320 ° C. Each tile was sequentially placed in the heating plate until the test ground began to melt, thereby "aging" the test ground. The smelting of the test soil was carefully observed, and Each tile was quickly removed after the floor It will begin to coalesce in large drops. This process was repeated. for each tile, letting the heating plate recover up to 320ºC between tiles. Subsequently, each tile was Let cool for at least 30 minutes.

To evaluate the cleanliness, a test tile treated was placed in a Gardner apparatus and immobilized. A 10 cm by 7.6 cm dry sponge was first moistened with 100 g of running water, and the excess was drained from the sponge. The sponge it was then embedded in a container with the appropriate size in the Gardner apparatus. An aliquot of 4-5 grams of one test formulation was then deposited directly in the floor surface of a tile, and left in contact with the tile for 15 seconds. From there, the Gardner Apparatus It was put in cycles from 3-6 strokes. The tile it was then washed with running water, and dried with compressed air of an airbrush compressor. This essay was repeated several times. for each formulation, using new treated test tiles For each evaluation.

The tiles tested were well evaluated by reflective means, that is, using a Minolta Chromometer to determine the change in reflectance between a tile without soil, untreated that was used as a "witness", and the reflectance of a floor tile that was cleaned using a amount of a composition of the invention according to the protocol Test described above. According to the reflective media, the Hard water removal percentage was determined using the following equation:

% \ from \ Removal = \ frac {\ text {RC \ hskip0,5cm - \ hskip0,5cm RS}} {\ text {RO \ hskip0,5cm - \ hskip0,5cm RS}} \ times 100

in the that

RC = Reflectance of the tile after cleaning with the test product

RO = Reflectance of the floor tile original

RS = Reflectance of the floor tile

For each tile, a number of readings were taken and the results were averaged to provide the Median readings for each tile. Five tiles were used to evaluate each of the test compositions and the average reading for each tile, as well as reading the average reflectance of the five tiles treated using a particular composition described in Table 1 are reproduced at continuation. These results can be compared with the reflectance of an untreated floorless tile that exhibited a average reflectance of 93.3% that was used as a "witness." The control tiles were evaluated, and the results are indicated in Table 4, below.

Evaluation of antimicrobial efficacy

Several of the formulations of the examples described in more detail in Table 1 above were evaluated to assess their antimicrobial efficacy against Staphylococcus aureus (gram-positive pathogenic bacteria) (ATCC 6538), Salmonella choleraesuis (gram-negative pathogenic bacteria) (ATCC 10708), Pseudomonas aeruginosa (ATCC 15442). The test was performed in accordance with the protocols outlined in Official AOAC METHOD 961.02 "Germicidal Spray Products as Disinfectants", as described in AOAC Official Methods of Analysis, 16 th Ed., (1995).

As seen by the professional expert in the technique, the results of the AOAC germicidal spray test indicate the number of test substrates in which the organism of test remains viable after being in contact for 10 minutes with a test disinfectant composition / total number of test substrates (plates) evaluated according to the test of AOAC germicidal sprayers. Thus, a result of "0/15" indicates that of the 15 test substrates that carry the organism of trial and they were in contact for 10 minutes with a test disinfectant composition, 0 test substrates had viable (live) test organisms at the conclusion of the test. Such a result is excellent, illustrating the excellent effectiveness. disinfectant of the composition tested.

The results of the tests are indicated in Table 5, below. The documented results indicate the number of test cylinders with living test organisms / number of test cylinders tested for each example formulation and tested organism.
