[0009] Detailed descriptions of one or more embodiments are provided herein. However, it should be understood that the present invention can be embodied in various forms. Accordingly, the specific details disclosed herein should not be construed as limiting, but rather as a basis for the claims and as representative basis for teaching one skilled in the art to employ the present invention in any suitable manner.

[0010] The singular forms "a," "an," and "the" include plural references unless the context clearly dictates otherwise. The use of the words "a" and "an" in the claims, when used in conjunction with the word "comprising" in the claims and / or specification, can mean "one," but is also consistent with the meaning of "one or more," "at least one," and "one or more than one."

[0011] Whenever any of the phrases "for example," "such as," "including," etc. are used herein, unless expressly stated otherwise, they are understood to be followed by the phrase "and without limitation." Similarly, "example," "exemplary," etc. are understood to be non-limiting.

[0012] The term "substantially" permits deviations from the descriptor that do not adversely affect the intended purpose. A descriptor is understood to be modified by the word "substantially," even if the word "substantially" is not explicitly recited.

[0013] Terms such as "comprising," "including," "having," and "involving" (and similarly, "comprises," "includes," "has," and "involving") are used interchangeably and have the same meaning. Specifically, each term is defined consistent with the general U.S. patent law definition of "comprising" and, therefore, is interpreted as an open term meaning "at least the following," and not excluding additional features, limitations, aspects, etc. Thus, for example, "a process involving steps a, b, and c" means that the process includes at least steps a, b, and c. Whenever the term "a" or "an" is used, it is understood to mean "one or more," unless such interpretation is meaningless in the context.

[0014] As used herein, the term "about" can refer to approximately, roughly, approximately, or in the region. When the term "about" is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the stated numerical values. In general, the term "about" is used herein to modify numerical values above and below the stated value by a variance of 20 percent above or below (higher or lower).

[0015] As used herein, the terms "substantially the same" or "substantially" may refer to taking into account variability typical of a particular method.

[0016] The terms "sufficient" and "effective," used interchangeably herein, can refer to the amount (e.g., mass, volume, dosage, concentration, and / or duration) necessary to achieve one or more desired result(s).

[0017] Before describing at least one embodiment of the present disclosure in detail, it should be understood that the present disclosure is not necessarily limited in its application to the details set forth in the following description or illustrated by way of example. The present disclosure is capable of other embodiments and of being practiced or carried out in various ways. Other compositions, compounds, methods, features, and advantages of the present disclosure will be or become apparent to one of ordinary skill in the art upon examination of the following figures, detailed description, and examples. All such additional compositions, compounds, methods, features, and advantages may be included herein and within the scope of the present disclosure.

[0018] FIG. 1 is a perspective view of a cleaning device (hereinafter referred to as a "scrubber," "scrubber device," "cleaning device," "foam scrubbing device," "foam scrubber," or "device") according to one embodiment. Device 100 includes a handle 102, a central body 104, and an array of scrubbing fins or dividers 106. As seen in FIGS. 6 and 7, central body 104 is structurally flexible (e.g., deformable) and includes a true octagonal shape, although embodiments are not so limited. In one embodiment, the octagonal shape may be irregular. Furthermore, the central body may include a greater or lesser number of straight line segments (equal or unequal) connected to form a closed polygon. The central body may also include a circle. The height of the central body is 10.00 mm. Embodiments of the device may include central bodies with greater or lesser heights. For example, the height of the central body can be about 3.0 mm, about 3.5 mm, about 4.0 mm, about 4.5 mm, about 5.0 mm, about 5.5 mm, about 6.0 mm, about 6.5 mm, about 7.0 mm, about 7.5 mm, about 8.0 mm, about 8.5 mm, about 9.0 mm, about 9.5 mm, about 10.0 mm, about 10.5 mm, about 11.0 mm, about 11.5 mm, about 12.0 mm, about 12.5 mm, about 13.0 mm, about 13.5 mm, about 14.0 mm, about 14.5 mm, or about 15 mm.

[0019] Continuing with the example shown in Figures 1-7, the central body 104 includes a lower surface 110 and an upper surface 115. As mentioned above, the distance between the upper and lower surfaces is 10.00 mm in one example. The handle 102 extends from the lower surface 110 of the central body 104. Three star-shaped projections cover the lower surface 110 of the device. The stars are aligned in a row across the lower surface. An array of scrubbing fins 106 extends from the upper surface 115 of the scrubbing device. The handle is attached to a first side 120 of the true octagonal central body and a second side 122 of the true octagonal central body. The handle features a through opening 124 that receives a user's hand during use of the device.

[0020] As seen in Figures 4 and 5, the handle 102 extends downward (away from the central body) while also following a curved trajectory toward the central axis of the device, defined by a line extending through point "A" in Figure 6. The first portion 130 of the handle follows a first radius of curvature. The second portion 134 of the handle follows a second radius of curvature. As the handle approaches its central portion 132 from either side, the radius of curvature increases, resulting in the central portion of the handle following a line with a shallower bend. As the handle's path approaches the second side, it follows a second radius of curvature that mirrors the first radius of curvature. At the handle's attachment points to the first and second sides of the central body, the handle has a thickness of 4.04 mm. At its central portion 132, the handle has a thickness of 3.25 mm. Note that the distance between the attachment points of the handle (on the first side 120 and the second side 122) is 110 mm. Of course, the handle is not limited to these dimensions. For example, the distance between the attachment points of the handle can be about 10 mm, about 15 mm, about 20 mm, about 25 mm, about 30 mm, about 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, about 75 mm, about 80 mm, about 85 mm, about 90 mm, about 95 mm, about 100 mm, about 105 mm, about 110 mm, about 115 mm, about 120 mm, about 125 mm, about 130 mm, about 135 mm, about 140 mm, about 145 mm, about 150 mm, or about 155 mm.

[0021] As seen in Figures 2 and 3, the handle has a width of 25 mm at its center. As the handle approaches the attachment points with the first and second sides 120 and 122, the handle spans a length of 40.06 mm on each side (Figure 7).

[0022] A user can control the cleaning device by simply extending their fingers through the handle with their palm facing the underside 110 of the central body 104. While the user applies the cleaning device to the body, the user's hand fits within the handle with an interference fit (as described further below). Of course, a user may grasp the handle in other ways. For example, a user may grasp the handle using a closed fist and apply the cleaning device to a target area of the body in a similar manner.

[0023] The scrubbing fins 106 extend upward from the upper surface 115 of the cleaning device. The fins are attached at their proximal ends to an inner portion 150 of the central body upper surface 115. The fins extend radially from the inner portion 150 of the upper surface 115. The inner portion 150 comprises a first circle 180 and a second circle 182 (seen in dashed lines in FIG. 6 ). The first circle has a radius of 10.0 mm, and the second circle has a radius of 14.99 mm. A first set of fins extends radially from the circumference of the first circle 180, and a second set of fins extends from the circumference of the second circle 182. The proximal ends of the first set of fins are equally spaced around the first circle, and the proximal ends of the second set of fins are equally spaced around the second circle.

[0024] The array of fins forms a wave pattern, with each fin following an alternating curved path extending from the central body inner portion 150. FIG. 8 shows a single fin 140 to illustrate the curved path. The fin 140 includes a first portion 142 and a second portion 144. The first portion has a first radius of curvature, and the second portion has a second radius of curvature. The first radius of curvature may be the same as the second radius of curvature. The transition from the first portion to the second portion may include an inflection point. In another embodiment, each fin may extend along a straight line. Additionally, the fins of the device may include various curved paths.

[0025] A plurality of radially extending fins circumferentially fill the central body's upper surface 115. The fins alternate between heights of 14 mm and 19 mm. Of course, alternative embodiments may include (i) fins of uniform height, or (ii) fins of varying heights. When the heights vary, the fins may be arranged in a circumferentially repeating pattern or in an irregular fashion. In some embodiments, the fins may be spaced apart at intervals of approximately 3.0 mm, approximately 3.5 mm, approximately 4.0 mm, approximately 4.5 mm, approximately 5.0 mm, approximately 5.5 mm, approximately 6.0 mm, approximately 6.5 mm, approximately 7.0 mm, approximately 7.5 mm, approximately 8.0 mm, approximately 8.5 mm, approximately 9.0 mm, approximately 9.5 mm, approximately 10.0 mm, approximately 10.5 mm, approximately 11.0 mm, approximately 11.5 mm, approximately 12.0 mm, approximately 12.5 mm, approximately 13.0 mm, approximately 13.5 mm, approximately 14.0 mm, approximately 15.0 mm, approximately 16.0 mm, approximately 17.0 mm, approximately 18.0 mm, approximately 19.5 mm, approximately 20.0 mm, approximately 21.0 mm, approximately 22.0 mm, approximately 23.0 mm, approximately 24.0 mm, approximately 25.0 mm, approximately 26.0 mm, approximately 27.0 mm, approximately 28.0 mm, approximately 29.0 mm, approximately 30.0 mm, approximately 31.0 mm, approximately 32.0 mm, approximately 33.0 mm, approximately 34.0 mm, approximately 35.0 mm, approximately 36.0 mm, approximately 37.0 mm, approximately 38.0 mm, approximately 39.0 mm, approximately 40.0 mm, approximately 41.0 mm, approximately mm, about 14.5 mm, about 15 mm, about 15.5 mm, about 16.0 mm, about 16.5 mm, about 17.0 mm, about 17.5 mm, about 18.0 mm, about 18.5 mm, about 19.0 mm, about 19.5 mm, about 20.0 mm, about 20.5 mm, about 21.0 mm, about 21.5 mm, about 22.0 mm, about 22.5 mm, about 23.0 mm, about 23.5 mm, about 24.0 mm, about 24.5 mm, or about 25 mm in height.

[0026] The top edge of each fin features a series of ridges. Each ridge is 2.5 mm high and 1.35 mm wide. The ridges are uniform in height and evenly distributed along the top edge of each fin. Of course, the height, width, and spacing dimensions may vary. Additionally, fins of alternative embodiments may feature ridges of various shapes, heights, widths, and spacings. In some embodiments, the ridge height is about 1 mm, about 1.5 mm, about 2 mm, about 2.5 mm, about 3 mm, about 3.5 mm, about 4 mm, about 4.5 mm, or about 5 mm. In some embodiments, the width of the ridge is about 0.5 mm, about 0.55 mm, about 0.6 mm, about 0.65 mm, about 0.7 mm, about 0.75 mm, about 0.8 mm, about 0.85 mm, about 0.9 mm, about 0.95 mm, about 1 mm, about 1.15 mm, about 1.25 mm, about 1.35 mm, about 1.45 mm, about 1.5 mm, about 1.55 mm, about 1.65 mm, about 1.75 mm, about 1.85 mm, about 1.95 mm, about 2 mm, about 2.15 mm, about 2.25 mm, about 2.35 mm, about 2.45 mm, about 2.5 mm, about 2.55 mm, about 2.65 mm, about 2.75 mm, about 2.85 mm, about 2.95 mm, or about 3 mm.

[0027] The cleansing devices of Figures 1-8 are used to apply a cleansing composition to a user's bodily skin. For purposes of this description, the cleansing composition may be a conventional bar soap. A user typically combines soap and water to generate suds, i.e., a foam made from soap and water. The cleansing device provides a structure that effectively delivers the cleansing composition to the skin surface while providing antibacterial properties during use and storage. In use, the fins of the device frictionally apply the water and soap to the user's skin. By way of example, the user may apply the device to an area of skin in a rotary and / or linear manner. The fins of the device capture the water and soap and deliver it to the bodily skin in a sweeping, circular, or reciprocating motion, thereby frictionally applying the soap suds and ridges of the fins to the skin surface.

[0028] As the device moves over the skin, the fins trap foam within a chamber. The chamber is defined by the top surface 115 of the device, the adjacent fin walls, and the user's skin. As shown, the fins extend radially from the interior of the central body. With reference to FIG. 7 (positioning a top view of the scrubber along the x- and y-axes), the user may move the device in a linear motion along the x-axis. As the user moves the device, they also apply downward pressure to the device. This downward pressure causes fins positioned transverse to the x-axis to collapse against each other in a brushing motion. During this motion, the upper edges of adjacent fins contact the skin. As the fins collapse together, the distance between the skin surface and the top surface of the device body decreases, thereby reducing the volume of the collapsing chamber and forcing foam from the chamber onto the skin. The collapsing effect increases as the radial axis of the fins becomes increasingly collinear with the y-axis. For example, the collapsing effect is greatest for fins extending along a line forming a 90-degree angle with the x-axis. As the angle increases from 90° to 180°, this effect decreases. Of course, the user can orient the device in various and mixed patterns that change the characteristics of this collapsing effect.

[0029] 9-15 show an alternative embodiment of a cleaning device. The alternative embodiment features a central body 204, a plurality of fins 206, and a handle 202. The alternative embodiment is similar to the device of FIGS. 1-8. The key difference is that the fins of the alternative embodiment do not feature ridges. The alternative embodiment is similarly dimensioned. However, the alternative embodiment may feature slightly different dimensions.

[0030] As one example, the height of the central body 204 is 9.00 mm. In some embodiments, the height of the central body can be about 3.0 mm, about 3.5 mm, about 4.0 mm, about 4.5 mm, about 5.0 mm, about 5.5 mm, about 6.0 mm, about 6.5 mm, about 7.0 mm, about 7.5 mm, about 8.0 mm, about 8.5 mm, about 9.0 mm, about 9.5 mm, about 10.0 mm, about 10.5 mm, about 11.0 mm, about 11.5 mm, about 12.0 mm, about 12.5 mm, about 13.0 mm, about 13.5 mm, about 14.0 mm, about 14.5 mm, or about 15 mm. As another example (as seen in FIGS. 12 and 13 ), the handle 202 comprises a thickness of 3.00 mm at its attachment points to the first and second sides 220 and 222 of the central body. The handle has a thickness of 3.00 mm at its central portion 232. Note that the distance between the handle's attachment points (on the first side 220 and second side 222 of the central body) is 110 mm. In some embodiments, the distance between the handle's attachment points can be about 10 mm, about 15 mm, about 20 mm, about 25 mm, about 30 mm, about 35 mm, about 40 mm, about 45 mm, about 50 mm, about 55 mm, about 60 mm, about 65 mm, about 70 mm, about 75 mm, about 80 mm, about 85 mm, about 90 mm, about 95 mm, about 100 mm, about 105 mm, about 110 mm, about 115 mm, about 120 mm, about 125 mm, about 130 mm, about 135 mm, about 140 mm, about 145 mm, about 150 mm, or about 155 mm. As seen in Figures 10 and 11, the handle has a width of 25 mm at its center. As the handle approaches the attachment points with the first and second sides 220 and 222, the handle spans a length of 39.76 mm on each side (Figure 15).

[0031] 9-15 show dimensions of a device according to another embodiment.

[0032] This specification describes non-limiting examples of materials that can be used to manufacture the scrubber apparatus. It should be understood that many different materials can be used to form the scrubber apparatus. For example, materials can include combinations of polymers, reinforced polymers, vinyl, polyvinyl chloride (PVC), polydimethylsiloxane (PDMS), fluoropolymers, rubber, metals such as aluminum, steel, and copper, metal composites, carbon fiber, and other materials that can withstand destruction while preserving internal contents and maintaining internal sterility. For example, the scrubber apparatus body can be formed from a combination of materials that make up different components, such as silicone, injection silicone, and / or rubber. In an embodiment, the scrubber apparatus can be manufactured from silicone. As used herein, the term "silicone" can refer to polysiloxane, a polymer of siloxane.

[0033] In embodiments, the materials used to manufacture the scrubber device can be infused and / or coated with antibacterial, antifungal, and / or antifouling agents. In embodiments, the scrubber device can be formed from any suitable mixture, content, and / or formulation, and is formed from an antibacterial infuse. As used herein, the term "infuse" can refer to any compound or mixture of compounds that is infused and / or mixed into the materials used to manufacture the cleaning device. For example, the scrubber can be manufactured from silicone infused with agents that kill and / or stop the growth of microorganisms. Furthermore, in this manner, the infused silicone can prevent bacterial growth and / or other growth that can lead to unhealthy use, such as those found in porous bath and shower devices with highly porous fiber networks. Examples include loafers, mesh sponges, or poofers. Furthermore, in this manner, the device can last longer than traditional loafers or other porous bath and shower devices. Furthermore, in this manner, the device does not produce odors or other undesirable characteristics such as conventional loaf devices or other porous bath and shower devices.

[0034] In embodiments, antimicrobial and / or antifouling agents can include, but are not limited to, silver, silver phosphate, zinc, zinc pyrithione, isothiazolinone, quaternary ammonium, zwitterions, sulfobetaine, triazole compounds, triclosan, benzalkonium chloride (BAC), chlorhexidine, carboxybetaine, compounds, antibiotics, antifungals, penicillin, aminoglycosides, ofloxacin, erythromycin, tetracycline, chloramphenicol, titanium, cobalt, nickel, zirconium, molybdenum, tin, lead, gold, copper, other metals, combinations thereof, and the like.

[0035] In embodiments, the antimicrobial and / or antifouling agent may be present at a concentration of about 1 mg / kg, about 10 mg / kg, about 100 mg / kg, about 500 mg / kg, about 1 g / kg, about 5 g / kg, about 10 g / kg, about 15 g / kg, about 25 g / kg, about 50 g / kg, about 100 g / kg, about 500 g / kg, or about 1 kg / kg of scrubber body material. For example, the antimicrobial agent may be present at a concentration of about 15-30 g / kg per kg of scrubber body material. For example, silver phosphate may be infused into silicone at a concentration of about 15-30 g / kg.

[0041] To facilitate a more complete understanding of the present invention, the following examples are provided. The following examples illustrate exemplary modes of making and practicing the present invention. However, the scope of the present invention is not limited to the specific embodiments disclosed in these examples, which are for illustrative purposes only, as alternative methods may be utilized to achieve similar results.

[0042] Example 1 Non-Limiting Exemplary Antibacterial Tests The ISO-22196 test is a method for evaluating the antibacterial activity of plastic products. It can be used to evaluate the antibacterial properties of many material types, including coated or monolithic composite surfaces. Antibacterial activity can be measured using the following method: R=(Ut-U0)-(At-U0)=Ut-At where R is the antibacterial activity. U0 is the mean common logarithm of the number of viable bacteria in cells / cm2 recovered from untreated test specimens immediately after inoculation. Ut is the mean decimal logarithm of the number of viable bacteria in cells / cm2 recovered from untreated test specimens after 24 hours. At is the mean decimal logarithm of the number of viable bacteria in cells / cm2 recovered from the treated test specimens after 24 hours.

[0043] For common reference, the percent reduction is also reported in the notes section of the sample results.

[0044] explanation CFU - Colony forming units (typically quoted per unit volume of surface area). CFU is determined by bacterial plating of a test sample according to a specific method, followed by counting the resulting colonies. Untreated Control (UTC) - Untreated control sample material used to demonstrate normal test performance, showing healthy microbial growth. Interval - can refer to the point or time at which a result value is determined. TO indicates that the result is from the earliest possible time (e.g., <5 minutes) from inoculation to collection of the inoculated sample. Result - can refer to a measure of change or abundance. Result units indicate, for example, the actual measurement relative to a control value, which depends on the method or test requirements.

[0045] Notation of changes to published test methods: Some references are made to "plate count agar" for test method plating after neutralization and recovery of bacteria from the test sample. As standard practice, counts are performed on an appropriate plating medium (e.g., nutrient agar, tryptic soy agar) or as required by the particular organism being tested. Published standards refer to incubation conditions of 35°C + / - 1°C. Standard microbiological practice by other international methods is for incubation to occur at 37°C + / - 1°C. Test conditions performed are 37°C + / - 1°C unless other temperature conditions are specified.

[0046] Current laboratory standards: Test measurement uncertainty is based on established standards provided in SOP070601 (Measurement Uncertainty Estimates). Measurement uncertainties for this test method can be found in FORM071102 (Bacterial Inoculum OD Correlation Table).

[0047] The expanded uncertainty for the k=2 test method is for a 95% confidence level of Log10(0.136).

[0048] The uncertainty value (CFU) is calculated by converting the number of CFUs (C1) into a Log10 value (Log10C1) and adding the expanded uncertainty (Log10C1 * EU) and then multiplied by the Log10 value (LogC1 + / - (Log10C1 * EU)) and take the antilogarithm (1×10^(LogC1+ / -(Log10C1 * The results are back-transformed by taking the log(EU) to determine the upper and lower 95% confidence limits in CFU. Antibacterial performance is reported as both Log10 and % reduction relative to the untreated control sample.

[0049] Test sample results Outcome time point: (T0 or other time in the study) Time unit: "hours" Results: Log reduction rounded to the nearest tenth Unit: logarithmic decrease

[0050] Introduction ISO 22196 specifies a method for assessing the antimicrobial activity of plastic products. It is a commonly used method for assessing the antimicrobial properties of many material types, which may range from coated surfaces or surfaces of monolithic compositions.

[0051] test Inoculation preparation - After overnight incubation, transfer the test bacteria to the inoculum solution. Transfer the test bacteria to the prepared small volume of 1 / 500 NB. Make appropriate dilutions of this suspension at 1 / 500 NB to establish an estimated bacterial concentration, obtaining a bacterial concentration of 1E6 CFU / mL to 4E6 CFU / mL, with a target concentration of 2.5E6 CFU / mL.

[0052] Inoculation of specimens: The surface to be tested is the exposed outer surface of the product. - 0.1 mL of the prepared test inoculum is pipetted onto the test surface. - Cover the test inoculum with a piece of film measuring 30mm x 30mm and gently press down on the film so that the test inoculum spreads to the edges. - Ensure that the test inoculum does not leak past the edge of the film. - After inoculating the sample and applying the cover film, replace the lid of the Petri dish.

[0053] Incubation of inoculated test specimens The standard procedure for incubation of inoculated samples is to incubate the Petri dishes containing the inoculated test samples (including half of the untreated test sample) at a temperature of (37+ / -)°C and a relative humidity of 90% or greater for (24+ / -1) hours, unless otherwise stated.

[0054] Bacterial recovery After the required plate incubation, viable bacteria are counted to determine the recovered bacterial concentration for each sample replicate. Reagents: Nutrient Broth 2 (NB2), D / E Neutralizing Broth (D / E), Phosphate Buffered Saline (PBS), Tryptic Soy Agar, and Laboratory Reverse Osmosis Water, Deionized Equipment list: Orbital shaker incubator, balance, autorator, Linitest, water incubator, spectrophotometer pH meter / O2 measurement / conductivity meter hygrometer pipettor. Test Organism Stock ID / Lot # Staphylococcus aureus 6538 299040-1 E. coli 8739 305629

[0055] Sample preparation Each test material was prepared according to the requirements of the analytical method. Unless otherwise specified, each test sample was prepared in triplicate. When available, flat samples were obtained and cut into 50 x 50 mm pieces. Sample variability was adjusted as required for the standard test. Test samples were flat to allow for layering of a film on the sample surface during testing. At a minimum, samples were controlled to prevent evaporation of the inoculum from the sample surface during testing, which was visually confirmed after testing. Samples were cut into 40 x 40 mm pieces.

[0056] Sampling Procedure Unless specified, samples will be cut from the provided piece or, if pre-cut, will be used as received. Unless specified, provided samples will be treated as uniform and monolithic for testing purposes, and selection, bias, or other types of potential sample heterogeneity will be ignored unless instructions and notes for sample handling are provided.

[0057] calculation Antibacterial performance==R=(Ut-U0)-(At-U0)=Ut(24h)-At(24h) where R is the antibacterial activity. U0 is the mean common logarithm of the number of viable bacteria in cells / cm2 recovered from untreated test specimens immediately after inoculation. Ut is the mean decimal logarithm of the number of viable bacteria in cells / cm2 recovered from untreated test specimens after 24 hours. At is the mean decimal logarithm of the number of viable bacteria in cells / cm2 recovered from the treated test specimens after 24 hours.

[0058] Table 1 shows the measurement of antibacterial activity on plastic surfaces.

[0059] [Table 1]

[0060] Table 1 shows the results of the ISO-22196 test method for measuring the antimicrobial properties of solid or hard surface treatment test samples incubated with selected microorganisms. The microorganisms used herein include Staphylococcus aureus and Escherichia coli. In this test method, a bacterial inoculum is contacted with the test sample for a duration of 24 hours without allowing the inoculum to dry. Following this exposure, the inoculated bacteria are recovered and the concentration of the organisms is determined. Antimicrobial performance is determined by comparing the organisms recovered from untreated and treated materials after 24 hours of incubation. Antimicrobial performance is reported as both a Log10 and a % reduction relative to the untreated control sample. Table 1 shows that the "Foam Scrub" sample resulted in a 4.3 log10 reduction in S. aureus after 24 hours (i.e., a 99.99% reduction), while the untreated control sample increased from 3,340,000 CFU / mL of S. aureus at time 0 to 1.03E+07 CFU / mL of S. aureus after 24 hours. Additionally, the "Foam Scrub" sample resulted in a 4.7 log reduction of E. coli after 24 hours (i.e., >99.99%), whereas the untreated control sample increased from 1.320000 CFU / mL of E. coli at 0 hours to 1.29E+07 CFU / mL of E. coli at 24 hours.

[0062] Fungal growth assessment: 0 - No fungal growth 1 - slight growth (less than 10% coverage) 2-Mild growth (coverage 10%-30%) 3 - Moderate growth (coverage 30%-60%) 4 - Severe growth (60% to complete coverage) Note: A score of "1" is also applicable to evidence of growth from external contamination. Non-test organisms are included in the final score. The note indicates whether non-inoculated fungi are present.

[0063] Introduction The ASTM G21 method provides an evaluation of the fungal resistance of test materials. Test samples are placed on nutrient agar plates and inoculated with a mixed fungal spore inoculum. The inoculum consists of spores from A. brasiliensis, P. funiculosum, C. globosum, T. virens, and A. pullulans. The test samples are incubated at 28°C and greater than 90% relative humidity for 28 days. After the incubation period, the test samples are visually evaluated for the presence and extent of fungal growth. The test result score is based on the rating provided by the test method.

[0064] Evaluate the samples and assign a score according to the method scoring scheme. Use the grid scale to estimate the percent coverage of the test sample based on microscopic observation using a stereomicroscope.

[0065] Test Procedure Test samples (Figures 16A and 16B) and control samples (Figure 16C) are placed on nutrient agar media and sprayed with a mixed fungal spore suspension, which is applied to completely cover the sample surface with droplets from the mist spray on the sample surface and to inoculate the medium components of the sample plate. Each fungal culture is prepared at a spore concentration of approximately 1E6 spores / mL. Unless otherwise indicated, the standard test period is 28 days. The standard test environmental conditions are 28 + / - 2°C and relative humidity > 90%.

[0072] [Table 2]

[0073] Table 2 shows the results of ASTM G21, the standard practice for determining the resistance of synthetic polymeric materials to fungi. ASTM G21 is a qualitative antimicrobial test used to detect general fungistatic activity of materials. Test results are reported based on a 0-4 rating scale, and a test record is provided if a zone of inhibition or contact inhibition is present. The fungal growth ratings for these results are as follows: 0—no fungal growth, 1—slight growth (less than 10% coverage), 2—light growth (10%-30% coverage), 3—moderate growth (30%-60% coverage), and 4—severe growth (60%-total coverage). The "Foam Scrub" and untreated control samples were inoculated with spores from the following fungi: A. brasiliensis, P. funiculosum, C. globosum, T. virens, and A. pullulans. After 28 days, the "Foam Scrub" samples yielded a score of 2, while the untreated control yielded a score of 4. It was noted that the "Foam Scrub" sample had less than 30% coverage with fungal hyphae and spores, while the untreated control sample had more than 90% coverage with fungal hyphae and spores.
