Description

CLEANING FORMULATIONS WITH LIQUID REPELLENCY

CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to LT.S. Provisional Application Serial No. 62/718,230 filed on August 13, 2018, the contents of which are incorporated by reference herein in their entirety.

1. FIELD

[0001] The presently disclosed subject matter relates to cleaning formulations for three- dimensional textile surfaces and fibrous substrates, such as but not limited to carpets, rugs, upholstery, and fabrics. Specifically, the cleaning formulations of the present disclosure provide both effective stain removal and liquid repellency from future soiling. Such cleaning formulations comprise a functional resin, a surfactant, and a liquid solution carrier.

2. BACKGROUND

[0002] Liquid cleaning solutions are used for a variety of reasons, including for personal, commercial, and industrial cleaning applications. In particular, such cleaning solutions can remove various stains, dirt, dust, urine, soil, grease, oils, and the like from three-dimensional textile surfaces. Cleaning solutions can be applied as a ready -to-use or diluted prior to use. Additionally, they can be sprayed or otherwise applied directly to a surface, or can be carried on a substrate, such as a wet or premoistened wipe, brush, or as a concentrate for dilute and use applications by the end user.

[0003] Effective stain removal on carpets, upholstery, and other three-dimensional textiles and fibrous substrates is of particular concern for consumers. Of note, most stains have a liquid component or carrier that wets a textile, quickly spreads, and wicks along the textile backing when spilled. Examples of such stains include juice, wine, soft drinks, and urine. As such, current cleaning formulations for textiles and fibrous substrates focus on improved wettability in order to emulsify a stain and effectively clean the textile. However, residues left behind from these cleaning solutions often increase the wetting of the fibrous substrate, which increases the wetting, spreading, and wicking of future liquid stains. [0004] It is desirable, therefore, for a cleaning formulation to have adequate or necessary amounts of wetting properties to adequately clean a stained textile, but also provide liquid repellency, such as a hydrophobic barrier, to repel and prevent future staining and soiling, especially from water- based sources. The chemistry and mechanisms associated with improved or better liquid repellency characteristics, however, make it difficult to wet, treat, and clean stains. In fact, cleaning formulations currently commercially available either clean and treat stains or repel liquids and soils, but not both. Accordingly, such cleaning solutions cannot both clean stains and provide ongoing and future protection for a three-dimensional textile surface.

[0005] Thus, there remains a need in the art for cleaning formulations that are effective at soil removal and adequately clean stains from a three-dimensional fibrous surface, but also provide liquid repellency to prevent future staining by water-based soiling sources. The presently disclosed subject matter addresses these and other needs.

In certain embodiments, functional silicone resins can comprise D and T units (DT resins) or M and Q units (MQ resins). In other embodiments, functional silicone resins can comprise alternative combinations of units such as but not limited to MDT, MTQ, or QDT.

[0029] In certain embodiments, the functional resin of the present disclosure can be an amino alkyl functionalized resin; an amino alkyl functionalized MQ silicone resin; an unreacted MQ resin; a siloxane or silicone resin blend; a silicone polyvinyl acetate; a silicone polyvinyl acetate neutralized with ammonium hydroxide; or a silicone functionalized acrylic.

[0030] Nonlimiting examples of functional resins include Wacker® HC 303, Wacker® HC 321, Wacker® MQ-RESIN POWDER 803 TF, Wacker® HC 103, Wacker® HC 130, DOWSIL™ MQ-1640 Flake Resin; DOWSIL™ FA 4002 ID Silicone Acrylate; TEGOTOP® 210; and BELSIL® P 1101.

[0031] As embodied herein, the cleaning formulation can have about 0.001 wt-% to about 50 wt- % of active functional resin and/or polymer. In some embodiments, the active functional resin and/or polymer can be present in the cleaning formulation in an amount of from about 0.002 wt- % to about 45 wt-%, from about 0.003 wt-% to about 40 wt-%, from about 0.004 wt-% to about 35 wt-%, from about 0.005 wt-% to about 30 wt-%, from about 0.006 wt-% to about 25 wt-%, from about 0.007 wt-% to about 20 wt-%, from about 0.008 wt-% to about 17.5 wt-%, from about 0.009 wt-% to about 15.0 wt-%, from about 0.01 wt-% to about 12.5 wt-%, from about 0.02 wt-% to about 10.0 wt-%, or from about 0.05 wt-% to about 5.0 actives wt-%, based on the overall weight of the cleaning formulation.

it. Surfactants

[0033] The presently disclosed cleaning formulation can further comprise one or more surfactants. As embodied herein, the surfactant can be non-ionic or anionic. In alternative embodiments, the surfactant can be amphoteric. In the present disclosure, the surfactant can provide a cleaning function and can also provide wettability by modifying the surface tension of the cleaning formulation to ensure that that the resulting cleaning and liquid repellency functions are uniformly deposited. In some embodiments, the surfactant is primarily responsible for the cleaning function of the cleaning formulation. In certain embodiments, the surfactant allows the functional resin and/or polymer to adequately coat and protect the fibrous surface or textile substrate on which the cleaning formulation is applied and used. In some embodiments, two or more surfactants can be blended to optimize the hydrophile-lipophile balance (“HLB”) in the cleaning function of the cleaning formulation. In certain embodiments, two non-ionic surfactants of high and low HLB are used.

[0034] In certain embodiments, the surfactant can act as a wetting agent or superwetter additive. As used herein,“superwetter” refers to a surfactant that can reduce the equilibrium surface tension of water to less than about 30 dynes/cm, e.g., from about 20 dynes/cm to about 25 dynes/cm. In contrast, other surfactants generally reduce the surface tension of water to from about 30 dynes/cm to about 35 dynes/cm.

[0035] A person of ordinary skill will appreciate that any suitable non-ionic surfactant can be used in the presently disclosed cleaning formulations, including, but not limited to linear alcohol ethoxylates (“LAEs”), e.g, C9-nPareth-3, C9-nPareth-6, C9-nPareth-8, Undeceth-3, Undeceth-5, Undeceth-7, Undeceth-9, Ci2-i3Pareth-3, Ci2-i3Pareth-7, Ci2-i₅Pareth-3, C12-13 Pareth-7, and C 12- i₅Pareth-9; secondary alcohol ethoxylates, e.g. , C 12-14, 7-40 moles of ethylene oxide (“EO”); branched secondary alcohol ethoxylates, e.g. , alpha-[3,5-dimethyl-l-(2-methylpropyl)hexyl]- omega-hydroxy-Poly(oxy-l,2-ethanediyl)] (also known as TERGITOL™ TMN, available from The Dow Chemical Company, Midland, MI); nonylphenol ethoxylates, e.g. , nonylphenol polyethylene glycol ether (4-70 moles EO); octylphenol ethoxylates, e.g. , polyethylene glycol octylphenyl ether (4.5-55 moles EO); ethoxylated/propoxylated copolymers, e.g. , 2-ethyl hexanol ethylene oxide-propylene oxide (“EO-PO”) (CAS No. 64366-70-7); alkyl polyglucosides (“APGs”), e.g. , decyl/undecyl glucosides, lauryl glucosides, butyl glucosides, caprylyl/capryl glucosides, methyl glucosides, Cs-i4 alkyl polyglucosides, cocoglucosides; and/or polyethylene glycol (“PEG”) 14 dimethicone.

[0036] In particular embodiments, at least two non-ionic surfactants can be present in the cleaning formulation. For example, and not limitation, the cleaning formulation can include two or more linear alcohol ethoxylates, such as ETndeceth-3 (e.g, BIO-SOFT® Nl-3, available from Stepan Company, Northfield, IL) and C9-nPareth-8 (e.g, BIO-SOFT® N91-8, available from Stepan Company, Northfield, IL). Additionally or alternatively, the cleaning formulation can include PEG 14 dimethicone (e.g, ABIL® B 8843, available from Evonik Industries AG, Essen, Germany).

[0040] As embodied herein, the anionic surfactant can be used in the cleaning formulation in an active amount of from about 0.001 wt-% to about 15 wt-%. In some embodiments, the anionic surfactant can be present in the cleaning formulation in an amount of from about 0.0015 wt-% to about 12.5 wt-%, from about 0.002 wt-% to about 10.0 wt-%, from about 0.0025 wt-% to about 7.5 wt-%, from about 0.003 wt-% to about 5.0 wt-%, from about 0.0035 wt-% to about 2.5 wt-%, from about 0.004 wt-% to about 2.0 wt-%, from about 0.005 wt-% to about 1.5 wt-%, or from about 0.01 wt-% to about 1.0 wt-%.

[0042] In certain embodiments of the disclosed subject matter, the cleaning formulation can have one or more amphoteric surfactants. Such amphoteric surfactants are known in the art as a “mediator” or“buffer”, and are used in a specific order of addition. Amphoteric surfactants have the ability to change charge with pH from cationic (compatible charge with HC 303 amino alkyl MQ resin) to anionic (compatible with the anionics listed above). Non-limiting examples of amphoteric surfactants include lauramine oxide, cocamidopropyl amine oxide, decyl amine oxide, lauryl/myristoyl amidopropylamine oxide, myristamine oxide, myristyl/cetyl amine oxide, capryl/capramidopropyl betaine, cocamidopropyl hydroxysultaine, disodium cocoamphodipropionate, and cocamidopropyl betaine. In particular embodiments, the cleaning formulation includes ocamidopropyl betaine (Amphosol CA, Stepan). In certain embodiments, the ratio of amphoteric surfactant with an anionic surfactant is about 1 : 1.

[0043] As embodied herein, the amphoteric surfactants can be used in the cleaning formulation in an active amount of from about 0.001 wt-% to about 15 wt-%. In some embodiments, the amphoteric surfactants can be present in the cleaning formulation in an amount of from about 0.1 wt-% to about 12.5 wt-%, from about 0.1 wt-% to about 10.0 wt-%, from about 0.1 wt-% to about 7.5 wt-%, or from about 0.1 wt-% to about 6.0 wt-%.

in. Liquid Solution Carriers

[0044] As embodied herein, the presently disclosed cleaning solutions comprise a liquid solution carrier. The liquid solution carrier acts as a vehicle such that the functional resin and/or polymer can adequately coat and protect the fibrous surface or textile substrate on which the cleaning formulation is applied and used.

[0045] A person of ordinary skill will appreciate that any suitable liquid solution carrier can be used in the presently disclosed cleaning formulations, including, but not limited to an aqueous solvent such as is water. In some embodiments, the liquid solution carrier is deionized (“DI”) water.

iv. Additional Components

[0046] The presently disclosed cleaning formulation can further include one or more additional components. In certain embodiments, the cleaning formulation can include one or more of a solvent, an oxidant, a fragrance, and combinations thereof. These additional components aid in the stability of the cleaning formulation and can help the cleaning function. In other embodiments, one or more additional components provide for neutralization chemistry, corrosion inhibition, and/or act as a preservative. However, a person of skill in the art will appreciate that various components, e.g., those commonly used in the art in cleaning solutions, can also be present.

[0047] As embodied herein, the presently disclosed cleaning formulations can include one or more solvents. The one or more solvents can carry the cleaning formulation and wholly or partly evaporate upon its application to a three-dimensional fibrous surface, leaving behind a water repellent coating, e.g, comprising the functional resin. As such, the solvent can aid in drying. Solvents of the present disclosure can also act to dissolve any dirt, grease, oil, or oil-based stains on the fibrous surface. In certain embodiments, the solvent can have an impact on emulsion stability of the cleaning formulations. For example, and not by way of limitation, many solvents can break up microemulsions of the functional resin. In other embodiments, solvents can help and aid with malodor remediation.

[0048] Additionally, the use of a low volatility solvent can cause the cleaning formulation to coalesce on the fibrous surface. A person of skill in the art will appreciate that a solvent can be selected with a volatility suitable for use in the cleaning of fibrous surfaces and textiles, e.g., that does not evaporate under the conditions of storage, but readily evaporates upon application to the stained fibrous surface.

[0049] By way of example, and not limitation, suitable solvents include ethanol (e.g, denatured ethanol), methanol, butanol, acetone, isopropyl alcohol, propylene glycol, propanediol, ethylene glycol, butylene glycol, triethylene glycol, diethylene glycol, and dibasic esters. Suitable solvents can also include glycol ethers, such as, but not limited to, dipropylene glycol methyl ether, dipropylene glycol n-butyl ether, dipropylene glycol n-propyl ether, propylene glycol diacetate, propylene glycol methyl ether, propylene glycol n-butyl ether, propylene glycol n-propyl ether, propylene glycol phenyl ether, tripropylene glycol methyl ether, tripropylene glycol n-butyl ether, tripropylene glycol n-propyl ether, and dipropylene glycol dimethyl ether. In other embodiments, solvents can include linear silicone oils such as disiloxane, poly dimethyl siloxane of various molecular weights and of viscosities from about 0.65 mm²/s to 1,000,000 mm²/s, and hexamethylcyclotrisiloxane (D3) to dodecamethylcyclohexasiloxane (D6).

[0050] In certain embodiments, the solvent can comprise one or more glycol ethers. For example, in particular embodiments, the solvent can comprise propylene glycol n-butyl ether (such as DOWANOL™ PnB, available from The Dow Chemical Company, Midland, MI) and/or dipropylene glycol n-butyl ether (such as DOWANOL™ DPnB, available from The Dow Chemical Company, Midland, MI).

[0051] In certain embodiments, two or more solvents are present. For example, and not limitation, the cleaning formulation can comprise both of propylene glycol n-butyl ether and dipropylene glycol n-butyl ether.

[0052] As embodied herein, the one or more solvents can be present in the cleaning formulation in an amount of from about 0.001 wt-% to about 10 wt-%. In some embodiments, the solvent can be present in the cleaning formulation in an amount of from about 0.002 wt-% to about 10 wt-%, from about 0.003 wt-% to about 10 wt-%, from about 0.004 wt-% to about 10 wt-%, from about 0.005 wt-% to about 10 wt-%, from about 0.006 wt-% to about 10 wt-%, from about 0.007 wt-% to about 10 wt-%, from about 0.008 wt-% to about 10 wt-%, from about 0.009 wt-% to about 10 wt-%, from about 0.01 wt-% to about 10 wt-%, from about 0.02 wt-% to about 10 wt-%, from about 0.03 wt-% to about 10 wt-%, from about 0.04 wt-% to about 10 wt-%, or from about 0.05 wt-% to about 10 wt-%, based on the overall weight of the cleaning formulation.

[0053] In certain embodiments, the cleaning formulation can have about 0.001 wt-%, about 0.002 wt-%, about 0.003 wt-%, about 0.004 wt-%, about 0.005 wt-%, about 0.006 wt-%, about 0.007 wt- %, about 0.008 wt-%, about 0.009 wt-%, about 0.01 wt-%, about 0.02 wt-%, about 0.03 wt-%, about 0.04 wt-%, about 0.05 wt-%, about 0.06 wt-%, about 0.07 wt-%, about 0.08 wt-%, about 0.09 wt-%, about 0.1 wt-%, about 0.2 wt-%, about 0.3 wt-%, about 0.4 wt-%, about 0.5 wt-%, about 0.6 wt-%, about 0.7 wt-%, about 0.8 wt-%, about 0.9 wt-%, about 1.0 wt-%, about 1.5 wt- %, about 2.0 wt-%, about 2.5 wt-%, about 3.0 wt-%, about 3.5 wt-%, about 4.0 wt-%, about 4.5 wt-%, about 5.0 wt-%, about 5.5 wt-%, about 6.0 wt-%, about 6.5 wt-%, about 7.0 wt-%, about 7.5 wt-%, about 8.0 wt-%, about 8.5 wt-%, about 9.0 wt-%, about 9.5 wt-%, or about 10 wt-% of solvent, based on the overall weight of the cleaning formulation.

[0054] As embodied herein, the presently disclosed cleaning formulations can comprise an oxidant. The oxidant can provide additional cleaning function and odor control. In some embodiments, the oxidant provides odor control for chromophores and malodors susceptible to oxidation, such as anthocyanins and urea.

[0079] The cleaning formulation can be an aqueous or non-aqueous solution. In certain embodiments, the cleaning formulation is an aqueous solution. The cleaning formulation can have any suitable pH range from about 1 to about 14. For example, and not limitation, the pH of the cleaning formulation can range from about 1.5 to about 12, or from about 2 to about 10. In certain embodiments, the pH of the cleaning formulation can range from about 3 to about 7.5. In alternative embodiments, the pH of the cleaning formulation can range from about 5 to about 10, or from about 8 to about 10.

[0080] In the presently disclosed subject matter, the ratio of the functional resin and/or polymer to surfactant by actives weight ratio in the cleaning formulation is about 10: 1. In other embodiments, the ratio of functional resin to surfactant is about 5: 1, about 5.5: 1, about 6: 1, about 6.5: 1, about 7: 1, about 7.5: 1, about 8: 1, about 8.5: 1, about 9: 1, about 9.5: 1, about 10: 1, about 10.5: 1, about 11 : 1, about 11.5: 1, about 12: 1, about 12.5: 1, about 13 : 1, about 13.5: 1, about 14: 1, about 14.5: 1, or about 15: 1.

[0081] As embodied herein, the cleaning formulations clean and treat stains on fibrous surfaces, but also include liquid repellency by coating the fibrous surface being cleaned with a functional resin. This liquid repellency can protect the surface from being soiled in the future by water-based stains, such as urine or juice. In this manner, upon cleaning and treating a stained fibrous surface or textile with the cleaning formulation presently disclosed, liquid repellency not already present in the fibrous surface or textile from the originating manufacturer can remain in place after cleaning. It is believed that the liquid repellency acts as a protective uniform coating against future stains, and counters the likelihood that any cleaning residue will increase the wetting, spreading, and wicking of future liquid stains on the fibrous surface. Thus, the cleaning formulations of the present disclosure advantageously and unexpectedly impart liquid repelling properties to future and subsequent stains. That is, the cleaning formulations presently disclosed balance between delivering wettability to clean a textile and leaving a hydrophobic coating to repel future aqueous based stains.

[0082] Additionally, the presently disclosed cleaning formulations have another advantage in that they do not require fluorine-based chemistries as part of the cleaning function or the liquid repellency function. As such, these cleaning formulations can be preferred over fluorine-based and/or fluorocarbon-based cleaning compositions in certain applications.

[0083] Further, cleaning formulations presently disclosed can provide a softening benefit to fibrous surface and textiles, such as carpets or upholstery. The functional resin or polymer (z.e., silicone resin) with the liquid solution carrier provides lubricity as a result of the liquid-repelling hydrophobic barrier. This allows the fibrous surface, such as carpet or upholstery, to feel and become softer. Moreover, as a result of the liquid repellency from future water-based stains, the overall life of the three-dimensional surface, such as carpet fibers, can be prolonged. Additionally, the presence of a nonionic surfactant in the cleaning formulations reduce any crystallization chemistry that may result in“crunching” or stiffness of the fibrous surface or carpet after cleaning. Thus, the carpet fibers and textiles are more flexible when the cleaning and liquid repellency chemistry equilibrates.

[0084] The liquid repelling characteristic of the cleaning formulations are less susceptible to any sort of undesirable build-up or clumping. This is because the functional resin components not only repel future liquid-based stains, they also repel each other after attaching and coating the fibrous surface being cleaned. As a result, the self-repelling property allows for more even and uniform coating on all three-dimensional surfaces being cleaned and treated, without any agglomeration in one area and insufficient coating and liquid repellency in another.

D. APPLICATIONS

[0085] The presently disclosed cleaning formulations can be used in a wide variety of applications and can be suitable for cleaning three-dimensional textile surfaces and fibrous substrates, such as but not limited to carpets, rugs, upholstery, and fabrics. As embodied herein, the cleaning formulations can be used as a liquid solution for direct application to the surface being cleaned, e.g., by spraying or otherwise applying the cleaning formulation directly onto a fibrous surface. In certain embodiments, application can be by trigger spray or in aerosol form. Alternatively, the cleaning formulations can be disposed on a substrate, such as a foam, textile, or wipe, for application to a fibrous surface. In further embodiments, the cleaning formulations can be concentrated. For example, the cleaning formulation can be concentrated up to 10 times, based on the amounts ( e.g ., weight percentages) disclosed herein. Concentrated versions of the presently disclosed cleaning formulations can be diluted and used in a refillable bottle and/or in carpet extraction machines.

[0086] In addition to their use on textile and fibrous materials, the cleaning formulations disclosed herein can also be effective on other desirable surfaces, including hard surfaces. The hard surfaces can include but are not limited to porous surfaces such as granite. The cleaning formulation can be effective on additional hard surfaces including but not limited to countertops, floors, cabinets, and various table surfaces.

[0087] The efficacy of the cleaning formulation can be observed by treating a surface with the cleaning formulation, then applying a soil to the surface (or waiting for soil to accumulate) and cleaning it again. The amount of soil remaining after cleaning the surface can be visually observed and/or picked up and measured with an electrostatic substrate (e.g., a microfiber cloth). Additionally, the suitability of the consistency, volatility, and hydrophobicity of the cleaning formulation for a surface can be observed using various draw down tests. Additionally, depending on the surface material being cleaned, glossiness of a surface can also be observed.

[0088] The presently disclosed cleaning formulation advantageously cleans as well as protects against future soils. In particular, the cleaning formulations work to clean urine, soil, vomit, feces, among other stains as good if not better than commercially available products. However, in addition to cleaning, the cleaning formulations protect materials or substrates against resoil by repelling liquid of new soils. Repellency tests have demonstrated that after treatment with the cleaning solutions, when subjected to a stream of liquid, the liquid beads on the surface of the test surface. Likewise, the cleaning formulations prevent stains from wicking back into fibers from the base substrate, for example in carpet stains. Importantly, the cleaning formulations exhibit self-sensitivity in that they do not build up over time. Additionally, the unique formulations provide a softening benefit to material substrates. 5. EXAMPLES

[0089] The following examples are merely illustrative of the presently disclosed subject matter and they should not be considered as limiting the scope of the subject matter in any way.

EXAMPLE 1 : CLEANING FORMULATIONS

[0090] This example summarizes various cleaning formulations suitable for use in cleaning three- dimensional fibrous surfaces and providing liquid repellency from future stains and re-soiling. The cleaning formulations comprised functional resins, surfactants, and other components. The balance of the cleaning formulations comprised liquid solution carrier (in this example, DI water).

[0091] The cleaning formulations were prepared with various concentrations of the active ingredients— as Formulations 1A-1F— for application in various end uses. The compositions of Formulations 1A-1F are provided in Table 1, below. Each component is identified by chemical name, and where applicable, with its respective wt-% of“actives” as delivered from a commercial manufacturer. Accordingly, the weight percent of each component reflected in the six cleaning formulations of Table 1 is also as delivered.

Table 1. Cleaning Formulations ^L

^L Components in respective cleaning formulations is denoted by wt-% as delivered. * wt-% of actives reflects each component“as delivered.”

EXAMPLE 2: CLEANING AND LIQUID REPELLENCY TESTING

[0092] This example tested the six formulations disclosed in Example 1, Formulations 1A-1F, against four common types of stains common to fibrous substrates and textile surfaces: soil, urine, vomit, and feces. Each type of stain was sampled three times. The resulting Delta E (DE)— measuring the change in visual perception of the color of the carpet before and after cleaning— has been qualified and ranked on a modified five-tier scale of“excellent,”“good,”“average,” “below average,” and“poor.” The results are tabulated in Table 3. An average“Cleaning Aggregate” was also determined based on the three samples per each stain type and for each cleaning formulation.

[0093] In addition, after treating and cleaning each stain sample, each of the six cleaning formulations was also tested for liquid repellency to future liquid-based staining. Liquid repellency was measured via AATCC (American Association of Textile Chemists and Colorists) Test Method 193-2017, as reflected in Volume 93 (2018) of the AATCC Technical Manual.

[0094] The formulations were also compared to deionized water, which acts as a control when testing against water-soluble stains. The formulations tested as good as deionized water with respect to soil, urine, and vomit.

Table 2. Stain Treatment and Liquid Repellency Testing

[0095] Referencing Table 2, Cleaning Formulations 1 A, 1B, 1C, 1D, and 1E yielded very similar results in terms of stain cleaning and treating across the same type of stain. These formulations exhibited better stain-cleaning for urine, vomit, and soil, and average stain-cleaning for feces. Cleaning Formulation 1F showed slightly less stain-cleaning ability for vomit as compared to Formulations 1 A, 1B, 1C, 1D, and 1E, but appeared to treat fecal stains marginally better.

[0096] All six cleaning formulations shown in Table 2 demonstrated water repellency per AATCC TM 193-2017. Formulations 1A, 1B, 1C, 1D, and 1E showed a re-soil grade of zero and a repel score of 2, while Formulation 1F showed a re-soil grade of 1 and a repel score of 4.

[0097] Based on Example 2, the six cleaning formulations presently disclosed show both stain cleaning functions and liquid repellency. EXAMPLE 3: CLEANING FORMULATIONS

[0098] This example summarizes various cleaning formulations suitable for use in cleaning three- dimensional fibrous surfaces and providing liquid repellency from future stains and re-soiling. The cleaning formulations comprised functional resins, surfactants (inclusive of amphoteric surfactants), and other components. The balance of the cleaning formulations comprised liquid solution carrier (in this example, DI water).

[0099] The cleaning formulations were prepared with various concentrations of the active ingredients— as Formulations 3A-3I— for application in various end uses. The compositions of Formulations 3A-3I are provided in Table 3, below. Each component is identified by chemical name, and where applicable, with its respective wt-% of“actives” as delivered from a commercial manufacturer. Accordingly, the weight percent of each component reflected in the cleaning formulations of Table 3 is also as delivered.
