Abstract
Description
Title of the invention: Cleaning wipe comprising a hydrophobic polymer FIELD OF DISCLOSURE
[0001] The present case relates to a cleaning wipe comprising a hydrophobic polymer and methods of cleaning a substrate using the cleaning wipe. CONTEXT
[0002] A wide variety of pre-moistened wipe products are available for cleaning surfaces, for example, for household, automotive, medical, industrial, and personal use. Although the intended use may vary, they share several similar characteristics. For example, most cleaning wipes are rectangular or square in shape and are usually slightly larger than an average human hand. They are formed from a soft, thin material that may be single-ply or multi-ply and are pre-moistened with a cleaning composition. In some cases, in addition to cleaning, they soften or soothe the surface being wiped (e.g., personal hygiene wipes for human use). In other cases, they clean and condition the surface being wiped (e.g., furniture or automotive wipes).
[0003] Cleaning wipes are often sold in plastic or other packaging such as tubes, bags, or other containers, and users extract the wipe by pulling it through a hole or slit in the package. Preferably, the hole or slit may be covered by a lid or other mechanism to prevent the cleaning wipes from drying out. Typically, the container or package is preloaded with a supply of wipes. Some cleaning wipes are formed from a continuous series of material, having perforations to help separate one wipe from another, which is conformably folded or rolled for dispensing. Other conventional wipes are individually formed and separated from one another, and usually conformably folded for dispensing.Regardless, most wipes are packaged together for dispensing in some type of resealable container, to preserve the pre-moistening and prevent them from drying out.
[0004] A wide variety of cleansing wipes are commercially available to meet the diverse needs of consumers. For example, some consumers desire scented wipes, while others require wipes without dyes, odors, or perfumes. Still other consumers desire wipes containing lotions such as aloe vera, lanolin, or other materials, often with or without added alcohol. Still other consumers want soft wipes, or wipes free of lotion, alcohol, or other additives. Regardless of the varying consumer requirements, one critical element common to all cleaning wipes is the requirement for effective cleaning. When one cleaning wipe lacks sufficient cleaning properties, multiple cleaning wipes are used, resulting in unnecessary waste and time. Oils, dirt, and contaminants can spread when the cleaning wipe does not lift and absorb them effectively and adequately. Therefore, cleaning wipes with superior cleaning properties are desirable. DISCLOSURE SUMMARY
[0005] The cleansing wipes of the present disclosure are surprisingly effective at dislodging, absorbing, and removing contamination, including oils, makeup, and greasy contaminants. The effectiveness is due, at least in part, to a unique hydrophobic polymer that enhances the dispersion of the cleansing composition carried by the cleansing wipe. In addition, the hydrophobic polymer has a binding affinity with contaminants, thereby enhancing the ability of the cleansing wipes to quickly dislodge and absorb contaminants.In addition, the hydrophobic polymer reduces the surface tension in the cleansing composition, allowing smaller oil droplets to be dispersed throughout the composition providing robust and stable emulsions that successfully carry and deliver cleansing actives and other desirable active ingredients, for example, skin active ingredients in situations where the cleansing wipes are used to cleanse or treat the skin. Given these multiple benefits, cleansing wipes are particularly well-suited for lifting and removing makeup from the skin. Cleansing wipes typically include: .
[0006] (i) an insoluble flexible substrate, which may be a woven or non-woven substrate, in in which the substrate is impregnated with a cleaning composition; and
[0007] (ii) the cleaning composition, wherein the cleaning composition comprises:
[0008] (a) a hydrophobic polymer formed as a reaction product of an oil natural or food-derived and a methacrylate or acrylate polymer;
[0009] (b) one or more solvents capable of solubilizing the reaction product of (a);
[0010] (c) one or more surfactants; and
[0011] (d) water.
[0012] The insoluble flexible substrate may be a woven or nonwoven substrate and absorbs or carries the cleaning composition, i.e., the insoluble flexible substrate is impregnated with the cleaning composition. The insoluble flexible substrate may be formed from a variety of natural and synthetic materials. Further, the flexible substrate insoluble can be a foam, sponge, cotton wool, sheet, cloth or film.
[0013] The hydrophobic polymer is a reaction product of a natural or food-derived oil and an acrylate or methacrylate polymer. According to embodiments of the disclosure, however, the hydrophobic polymer is the reaction product of a natural or food-derived oil and a methacrylate polymer. The natural or food-derived oil may be a drying oil or a semi-drying oil. Non-limiting examples include linseed oil, sunflower oil, tung oil, fish oil, cottonseed oil, soybean oil, or combinations thereof. The methacrylate polymer may be formed from methacrylate monomers, for example, monomers selected from isobutyl methacrylate, methyl methacrylate, ethyl methacrylate, n-butyl methacrylate, or combinations thereof.In a preferred embodiment, the hydrophobic polymer is formed from a natural or food-derived oil and an isobutyl methacrylate polymer and may preferably be an isobutyl methacrylate polymer.
[0014] In various embodiments, the hydrophobic polymer is the reaction product of about 50 to about 85 parts by weight of the natural or food-derived oil and about 15 to about 50 parts by weight of the methacrylate or acrylate polymer. More specifically, the hydrophobic polymer may be the reaction product of about 72 to about 77 parts by weight of the natural or food-derived oil and about 23 to about 28 parts by weight of a methacrylate polymer. For example, the hydrophobic polymer may be the reaction product of linseed oil and poly(isobutyl methacrylate) in a suitable solvent, such as, for example, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. Preferably, the reaction product is about 72 to about 77% linseed oil and about 23 to about 28% isobutyl methacrylate polymer in a suitable solvent, such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate.
[0015] One or more solvents capable of solubilizing the hydrophobic polymer of (a) are used to solubilize the hydrophobic polymer. A single solvent may be used or a combination of solvents, wherein the combination of solvents can solubilize the hydrophobic polymer of (a). In various embodiments, the one or more solvents capable of solubilizing the reaction product of (a) have a dispersion component (D), a polar component (P), and a hydrogen bonding component (H), and a distance (Ra) of less than or equal to 13.4 MPa0.5 by Hansen solubility parameter, wherein the distance (Ra) is defined by formula (I): [0°16] Ra = (I)
[0017] in which • Dr is 16.8 MPa0'5, • Pi is 4.8 MPa0'5, and • Hr is 13.0 MPa0'5.
[0018] Non-limiting examples of solvents capable of solubilizing the hydrophobic polymer of (a) include polycitronellol acetate, caprylic / capric triglyceride, isododecane, isohexadecane, tetradecane, isopropyl myristate, isopropyl alcohol, octyldodecanol, ethanol, phenoxyethanol, castor oil, and mixtures thereof. Polycitronellol acetate is particularly useful.
[0019] Surfactants include anionic surfactants, cationic surfactants, amphoteric (zwitterionic) surfactants, and nonionic surfactants. In various embodiments, the cleaning composition includes one or more anionic surfactants, and optionally, one or more nonionic surfactants. Anionic surfactants are useful for their detergent properties. They are effective cleaners and can contribute to foam formation, if desired. Non-limiting examples of anionic surfactants include glutamates, acyl taurates, alkanoyl isethionates, alkyl succinates, alkyl sulfosuccinates, N-alkyl sarcosinates, alkyl phosphates, alkyl ether phosphates, alkyl ether carboxylates, alpha-olefin sulfonates, or combinations thereof. In various embodiments, the cleaning composition includes one or more acyl taurate surfactants.
[0020] One or more of the surfactants may be a biosurfactant. Non-limiting examples of biosurfactants include glycolipids (e.g., sophorolipids, rhamnolipids, cellobiose lipids, mannosylerythritol lipids, and trehalose lipids), lipopeptides (e.g., surfactin, iturin, fengycin, arthrofactin, and lichenysin), flavolipids, phospholipids (e.g., cardiolipins), fatty acid ester compounds, fatty acid ether compounds, and high molecular weight polymers such as lipoproteins, lipopolysaccharide-protein complexes, and polysaccharide-protein-fatty acid complexes. Preferably, at least one of the biosurfactants is a glycolipid.Non-limiting examples of glycolipids include sophorolipids, rhamnolipids, trehalose lipids, mannosylerythritol lipids, and combinations thereof, wherein rhamnolipids are particularly preferred.
[0021] The cleaning composition includes a substantial amount of water, which forms all or part of the aqueous phase of the cleaning composition. In addition, the aqueous phase may include one or more water-soluble solvents, hydrophilic active agents, salts, etc. Similarly, the oily phase, in addition to the hydrophobic polymer, may include one or several lipophilic active agents, for example, one or more skin active agents such as ceramides, cholesterol, etc.
[0022] Methods of cleaning a surface using the cleaning wipes are also described. For example, in a preferred embodiment, the cleaning wipes are particularly useful for cleaning skin and for removing makeup from the skin. DETAILED DESCRIPTION OF THE DISCLOSURE
[0023] The present disclosure relates to cleansing wipes impregnated with a cleansing composition. The cleansing composition is typically an oil-in-water emulsion comprising a hydrophobic polymer. The cleansing composition provides improved cleansing properties and is surprisingly robust, versatile, and useful for carrying and delivering cosmetic ingredients, including skin active agents. The cleansing wipe typically comprises:
[0024] (i) an insoluble flexible substrate, which may be a woven or non-woven substrate, in in which the substrate is impregnated with a cleaning composition; and
[0025] (ii) the cleaning composition, wherein the cleaning composition comprises:

[0030] The cleaning composition is preferably an oil-in-water emulsion. In various embodiments, the oil-in-water emulsion comprises oil droplets having an average size of about 10 nm to about 1 μm.
[0031] The cleansing composition may optionally include a variety of additional ingredients. For example, in some embodiments, the cleansing composition includes one or more skin active agents, vitamins, thickening agents, water-soluble solvents, fatty acids, fatty alcohols, or combinations thereof. Non-limiting examples of skin active agents include anti-wrinkle agents, anti-inflammatory agents, depigmenting agents, skin renewal compounds, compounds that improve skin barrier function, anti-aging compounds, and the like.
[0032] Due to the stability, versatility, and multiple phases (oil / water) of the cosmetic composition, the cosmetic compositions may include a variety of different skin active agents. For example, the oil phase of the cosmetic composition may include one or more lipophilic skin active agents. The aqueous phase of the cosmetic composition may include one or more hydrophilic skin active agents. Non-limiting examples of useful skin active agents include ceramides, ceramide precursors, cholesterol, cholesterol sulfate, b-glucan, carob seed extract, eperua falcata extract, amino acids, niacinamide and its derivatives, hyaluronic acid and its derivatives, allantoin, omega fatty acids, vitamins, vitamin precursors, retinoids including retinol, retinoic acid, tretinoin, isotretinoin, adapalene, or combinations thereof.

[0035] An “insoluble” substrate is one that does not readily dissolve or decompose upon immersion in water and upon immersion in the cleaning composition that the insoluble flexible substrate carries. A wide variety of materials may be used. The following non-limiting characteristics are desirable: (i) sufficient wet strength for use, (ii) sufficient abrasiveness, (iii) sufficient bulk and porosity, (iv) sufficient thickness, and (v) suitable size. The term “flexible” with respect to the insoluble flexible substrate means that the substrate is readily deformable and pliable. A typical cotton cleaning cloth is an example of a flexible backing. The insoluble flexible substrate is absorbent, i.e., capable of absorbing liquid through the surface and retaining it.
[0036] The insoluble flexible substrate may be a woven or non-woven substrate and absorbs or carries the cleaning composition, i.e., the insoluble flexible substrate is impregnated with the cleaning composition. The insoluble flexible substrate may be formed from a variety of natural and synthetic materials. Further, the insoluble flexible substrate may be a foam, sponge, wadding, sheet, cloth, or film.
[0037] Non-limiting examples of suitable insoluble flexible substrates that meet the above criteria include nonwoven substrates, woven substrates, hydroentangled substrates, air-entangled substrates and the like. Preferred embodiments utilize nonwoven substrates because they are economical and readily available in a variety of materials. By nonwoven is meant that the layer is composed of fibers that are not woven into a fabric, but rather formed into a sheet, especially a thin paper. The fibers may be random (i.e., randomly aligned) or they may be carded (i.e., combed to be oriented primarily in one direction). In addition, the nonwoven substrate may be composed of a combination of random and carded fiber layers.
[0038] The insoluble substrate may comprise one or more layers and may be chosen from woven materials, non-woven materials, foams, sponges, wadding, sheets, fabric or films. It may be a non-woven or woven substrate based on fibers of natural origin (linen, wool, cotton, silk, bamboo fibers) or of synthetic origin (cellulose derivatives, viscose, polyvinyl derivatives, polyesters, such as polyethylene terephthalate), polyolefins, such as polyethylene (PET) or polypropylene, polyamides, such as nylon, or acrylic derivatives), and their mixtures, such as viscose / PET, polylactic acid (PLA) or viscose / polylactic acid (viscose / PLA).
[0039] Nonwoven substrates may be composed of a variety of natural and synthetic materials. By natural, it is meant that the materials are derived from plants, animals, insects or by-products. By synthetic, it is meant that the materials are obtained primarily from various artificial materials or from a material that is usually a fibrous web comprising one of the common synthetic or natural fibers of textile length, or mixtures thereof.
[0040] Non-limiting examples of useful natural materials include silk fibers, keratinous fibers, and cellulosic fibers. Non-limiting examples of keratinous fibers include those selected from wool fibers, camel hair fibers, and the like. Non-limiting examples of cellulosic fibers include those selected from wood pulp fibers, cotton fibers, hemp fibers, jute fibers, flax fibers, and mixtures thereof.
[0041] Non-limiting examples of useful synthetic materials include those selected from acetate fibers, acrylic fibers, cellulose ester fibers, modacrylic fibers, polyamide fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon fibers, and blends thereof. Examples of some of these synthetic materials include acrylics such as Acrylan®, Creslan® and the acrylonitrile-based fiber, Orlon®; cellulose ester fibers such as cellulose acetate, Arnel® and Acele®; polyamides such as nylons (e.g., Nylon 6, Nylon 66 and Nylon 610); polyesters such as Fortrel®, Kodel® and Dacron®; polyolefins such as polypropylene, polyethylene; polyvinyl acetate fibers, and blends thereof.
[0042] Woven substrates include knitted substrates and are often made from yarns or strings of natural or synthetic material woven into a cloth. Non-limiting examples include fabric and cloth. For example, cotton, polyester, and the like.
[0043] Nonwoven substrates made from natural materials consist of webs or sheets that are generally formed on a fine metal screen from a liquid suspension of the fibers. Substrates made from natural materials may be obtained from a wide variety of commercial sources.

[0045] The insoluble substrates comprise two or more layers, each having a different texture and abrasiveness. The different textures may result from using different combinations of materials or from using a substrate having a more abrasive side for exfoliation and a softer, absorbent side for gentle cleaning. In addition, separate layers of the substrate may be manufactured to have different colors, which helps the user further distinguish the surfaces.
[0046] The substrate may be of any size and shape suitable for the intended use. In addition, it generally has a surface area of between 0.005 m2 and 0.1 m2, preferably between 0.01 m2 and 0.05 m2.
[0047] The impregnation rate of the composition on the substrate is generally from 100 to 1000%, preferably from 250 to 700% by weight of the substrate. Techniques for impregnating substrates with compositions are well known in the art and are all applicable to the present case. In general, the impregnating composition is optionally heated and added to the substrate by one or more techniques including dipping, coating, spraying, etc.
[0048] A number of wipes are generally stored together in a single pouch, for example 1 to 500, 1 to 100, or 5 to 50 individual wipes may be stored in a dispensing pouch or container, preferably a moisture impervious pouch or container. During storage and between dispensations, the pouch or container is preferably reclosable. Pouches containing a single wipe may also be employed.
[0049] The amount of impregnating composition (cleaning composition) relative to the substrate may range from about 20:1 to 1:20, preferably from 10:1 to about 1:10 and more preferably from about 2:1 to about 1:2 by weight. The cleaning wipe may be loaded with at least 1, 1.5 or 2 grams of the cleaning composition, as described herein, per gram of dry substrate, but typically not more than 5 grams per gram. (a) Hydrophobic polymer
[0050] The hydrophobic polymer is a reaction product of a natural or food-derived oil (oily component) and an acrylate component. In particular, the natural or food-derived oil may be a drying oil, preferably oil of flax. The reaction product may preferably include an isobutyl methacrylate backbone with a plurality of linseed oil side chains. Preferably, the reaction product is a product sold under the trademark MYCELX® from MYCELX Technologies Corporation of Gainesville, Georgia. See U.S. Patent No. 5,698,139 for a description of MYCELX materials.
[0051] The hydrophobic polymer comprises an oil component and a polymer component, typically reacted in a solvent. In a preferred embodiment, the hydrophobic polymer is a reaction product of linseed oil and poly(isobutyl methacrylate) in a solvent, such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate.
[0052] The oil component is derived from glycerin and carboxylic acids, such as flaxseed fatty acid to form monoglycerides, diglycerides, and triglycerides. The oil component is preferably of vegetable or natural origin. Vegetable oils are obtained by cold pressing the seeds of a plant to obtain the oil contained therein. Among the vegetable oils, drying oils such as linseed oil and tung oil, semi-drying oils such as soybean oil and cottonseed oil, and non-drying oils such as coconut oil can be used as the oil component. The oil component typically forms about 72% to 77%, or most preferably 74.62%, of the hydrophobic polymer (e.g., linseed oil / isobutyl methacrylate).
[0053] The polymer component may be derived from α- and β-unsaturated carbonyl compounds. The polymer component is the resulting product of a monomer that is an ester of acrylic acid, crotonic acid, isocrotonic acid, methacrylic acid, sorbic acid, cinnamic acid, maleic acid, fumaric acid, or methyl methacrylic acid. Non-limiting examples of useful polymers that cover any number of reaction possibilities between esters of these compounds include acrylate polymers, methyl methacrylate polymers, methyl / n-butyl methacrylate polymers, methacrylate copolymers, ethyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, n-butyl / isobutyl methacrylate copolymers, or combinations thereof.
[0054] Preferably, the polymer is poly(isobutyl methacrylate). In particular, the percentage of polymer may be from about 23% to about 28%, or about 25.28%, of the hydrophobic polymer, e.g., poly(linseed oil / isobutyl methacrylate). The hydrophobic polymer is a reaction product typically formed in a liquid solvent capable of dissolving or diluting the polymer component and the reaction product, i.e., the hydrophobic polymer (poly(oil / polymer)). The solvent or diluent should generally comprise any liquid or mixture of liquids capable of dissolving or diluting the hydrophobic polymer. The solvent / diluent may control evaporation, desired flow and coalescence of the hydrophobic polymer. The solvent may be, for example, an aliphatic hydrocarbon, an aromatic hydrocarbon, alcohols, ketones, ethers, aldehydes, phenols, carboxylic acids, carboxylates, synthetic chemicals and naturally occurring substances. Preferably, the solvent is 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The hydrophobic polymers according to the present disclosure and methods for making them are described, for example, in U.S. Patent Nos. 5,437,793, 5,698,139, 5,837,146, 5,961,823, 6,180,010, 6,475,393 and 6,805,727.
[0055] The amount of hydrophobic polymer in the cleaning composition will vary but is often in an amount of about 0.1 to about 15% by weight, based on the total weight of the cleaning composition.In other embodiments, the total amount of hydrophobic polymer in the cleaning composition is about 0.1 to about 12 wt. %, about 0.1 to about 10 wt. %, about 0.1 to about 8 wt. %, about 0.1 to about 5 wt. %, about 0.1 to about 3 wt. %, about 0.5 to about 15 wt. %, about 0.5 to about 12 wt. %, about 0.5 to about 10 wt. %, about 0.5 to about 8 wt. %, about 0.5 to about 5 wt. %, about 0.5 to about 3 wt. %, about 1 to about 15 wt. %, about 1 to about 12 wt. %, about 1 to about 10 wt. %, about 1 to about 8 wt. % by weight, from about 1 to about 5% by weight, from about 1 to about 3% by weight, from about 2 to about 15% by weight, from about 2 to about 12% by weight, from about 2 to about 10% by weight, from about 2 to about 8% by weight, from about 2 to about 5% by weight, based on the total weight of the cleaning composition.

The one or more solvents may include a solvent used in the reaction to form the hydrophobic polymer, for example, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The one or more solvents may be a single solvent or a plurality of solvents. For example, in various embodiments, the solvents capable of solubilizing the hydrophobic polymer of (a) have a dispersion component (D), a polar component (P), a hydrogen bonding component (H), and a distance (Ra) of less than or equal to 13.4 MPa0.5 according to Hansen solubility parameters, wherein the distance (Ra) is defined by formula (I): [°°57] Ra - W + (p ~ P^ + ~ (I)
[0058] in which • Dr is 16.8 MPa0'5, • Pi is 4.8 MPa0'5, and • is worth 13.0 MPa0'5.
[0059] In a preferred embodiment, the one or more solvents have a dispersion component (D), a polar component (P), a hydrogen bonding component (H) and a distance (Ra) less than or equal to 9.9 MPa0.5 according to Hansen solubility parameters, wherein the distance (Ra) is defined by formula (I): 100601 ®

[0062] The solvent may be an oil. The term "oil" is intended to refer to a non-aqueous, water-immiscible compound that is liquid at 25°C and atmospheric pressure (760 mmHg; 1.013 x 105 Pa). The solvent may be a non-silicon oil (e.g., an oil that does not contain silicon atoms, and in particular does not contain Si-O groups). Non-limiting examples of the one or more solvents (b) include caprylic / capric triglyceride, isopropyl myristate, and polycitronellol acetate. The solvent may include acetone. The solvent may include oleic acid. The solvent may include an oleic acid containing oil (such as a vegetable oil).

[0063] [Tables 1] Table 1 Solvent (b) DPH Ra (Allowable Range) Ra (Preferred Range) Ethanol 15.8 8.8 19.4 7.81 8.67 Octyldodecanol 16.1 2.2 7.4 6.33 5.17 Isopropyl Myristate 15.9 2.1 2.8 10.70 9.41 Isopropyl Alcohol 15.8 6.1 6.4 7.02 5.54 Phenoxyethanol 17.8 5.7 14.3 2.55 3.88 CCTG 18.22 5.39 14.74 3.38 4.76 Castor Oil 15.9 4.6 12 2.07 1.12 Polycitronellol acetate 16.4 3 4.2 9.02 7.76 Acetone 15.5 10.4 7 8.61 7.38 Oleic acid 16 2.8 6.2 7.27 5.98
[0064] In some embodiments, if oleic acid is used, at least a portion of the oleic acid may be provided by a vegetable oil. The vegetable oil may be a seed or nut oil. The vegetable oil may have an oleic acid content of at least 20% by weight of the vegetable oil. The vegetable oil may include sunflower oil, soybean oil, macadamia nut oil, and / or avocado oil. In some embodiments, the solvent may include macadamia nut oil, and may be free, or substantially free, of other vegetable oils.
[0065] For the purposes of the present disclosure, the one or more solvents capable of solubilizing the hydrophobic polymer of (a) may not individually solubilize the hydrophobic polymer of (a) but, when combined with other solvents, the combination solubilizes the hydrophobic polymer of (a). Thus, when referring to a total amount of one or more solvents capable of solubilizing the hydrophobic polymer of (a), the inclusion of all solvents that in combination solubilize the hydrophobic polymer of (a) is intended, even if one or more solvents in the combination do not individually solubilize the hydrophobic polymer of (a).
[0066] Non-limiting examples of solvents for solubilizing the hydrophobic polymer of (a), individually or in combination with other solvents, include polycitronellol acetate, caprylic / capric triglyceride, isododecane, isohexadecane, tetradecane, isopropyl myristate, octyldodecanol, ethanol, phenoxyethanol, castor oil, and mixtures thereof.

[0068] The total amount of the one or more solvents capable of solubilizing the hydrophobic polymer of (a) in the cleaning composition will vary and may be adjusted depending on the desired hydrophobic / lipophilic properties and the intended target to be cleaned. In some embodiments, it is desirable to have a smaller oil phase and, therefore, a smaller amount of the one or more solvents is required. In other embodiments, it is useful to have a larger oil phase, so that a higher amount of the one or more solvents is required.
[0069] It may be useful to have a large aqueous phase. In this case, the total amount of the one or more solvents capable of solubilizing the hydrophobic polymer (a) may be from about 0.05 to about 10% by weight, based on the total weight of the cleaning composition.

(c) Surfactant
[0071] For the purposes of this disclosure, the term "surfactant" includes emulsifiers and detergents. Surfactants, or surface agents, are compounds that reduce the surface tension between two liquids or between a liquid and a solid. Surfactants are amphiphilic, meaning they contain hydrophilic (water-loving) head groups and hydrophobic (water-hating or oil-loving) tails. Surfactants adsorb at the interface between oil and water, thereby decreasing the surface tension.
[0072] As used herein, an “emulsifier” is a surfactant that stabilizes emulsions. Emulsifiers coat the droplets of an emulsion and prevent them from clumping together or coalescing. An “emulsion” is a mixture of two or more liquids, with or without an emulsifier, that are normally immiscible. One of the liquids, the “dispersed phase,” forms droplets in the other liquid, the “continuous phase.”
[0073] A "detergent" is a surfactant that has cleaning properties in dilute solutions and is typically anionic.
[0074] The surfactants may be anionic, cationic, amphoteric (zwitterionic), or nonionic. Preferably, the emulsions of the present invention include one or more surfactants selected from anionic surfactants, amphoteric (zwitterionic) surfactants, nonionic surfactants, or mixtures thereof. In various embodiments, the emulsions are preferably free or essentially free of cationic surfactants. In other embodiments, the emulsions include one or more cationic surfactants. In preferred embodiments, the emulsions contain one or more biosurfactants, one or more anionic surfactants, optionally one or more non-ionic surfactants, or mixtures thereof.
[0075] In a preferred embodiment, the compositions of the present disclosure include a plurality of surfactants, wherein the plurality of surfactants includes one or more biosurfactants and one or more surfactants other than the one or more biosurfactants. In other embodiments, the compositions of the present disclosure include one or more biosurfactants, one or more anionic surfactants, and, optionally, one or more nonionic surfactants.
[0076] The total amount of the one or more surfactants in the cleaning composition will vary but is typically from about 0.5 to about 20% by weight, based on the total weight of the cleaning composition. In other embodiments, the total amount of the one or more surfactants in the cleaning composition is about 0.5 to about 15% by weight, about 0.5 to about 12% by weight, about 0.5 to about 8% by weight, about 0.5 to about 6% by weight, about 1 to about 20% by weight, about 1 to about 15% by weight, about 1 to about 12% by weight, about 1 to about 10% by weight, about 1 to about 8% by weight, about 1 to about 6% by weight, about 2 to about 20% by weight, about 2 to about 15% by weight, about 2 to about 12% by weight, about 2 to about 10% by weight, about 2 to about 8% by weight, about 2 at about 6% by weight, from about 3 to about 20% by weight,from about 3 to about 15% by weight, from about 3 to about 12% by weight, from about 3 to about 10% by weight, from about 3 to about 8% by weight, from about 3 to about 6% by weight, from about 4 to about 20% by weight, from about 4 to about 15% by weight, from about 4 to about 12% by weight, from about 4 to about 10% by weight, from about 4 to about 8% by weight, from about 4 to about 6% by weight, based on the total weight of the cleaning composition. Biosurfactant
[0077] The compositions of the present disclosure may optionally include one or more biosurfactants. Biosurfactants are amphiphilic molecules, e.g., glycolipids (e.g., sophorolipids, rhamnolipids, cellobiose lipids, mannosylerythritol lipids, and trehalose lipids), lipopeptides (e.g., surfactin, urin, fengycin, arthrofactin, and lichenysin), flavolipids, phospholipids (e.g., cardiolipins), fatty acid ester compounds, fatty acid ether compounds, and high molecular weight polymers such as lipoproteins, lipopolysaccharide-protein complexes, and polysaccharide-protein-fatty acid complexes.
[0078] Biosurfactants are environmentally friendly, biodegradable and non-toxic and can be classified into high and low molecular weight biosurfactants. Low molecular weight biosurfactants effectively reduce surface and interfacial tension, and high molecular weight biosurfactants are more effective as emulsion stabilizing agents. Examples of low molecular weight biosurfactants include glycolipids, such as rhamnolipids, sophorolipids, lipopeptides, and trehalolipids. These low molecular weight biosurfactants have hydrophilic heads composed of sugar units glycosidically linked to hydrophobic nonpolar moieties. Examples of high molecular weight biosurfactants include polysaccharides, lipopolysaccharides, proteins, and lipoproteins. Polysaccharide-based biosurfactants can be classified into sorbitan esters, sucrose esters, and glucose-based surfactants, which include alkyl polyglycosides and fatty acid glucamides.
[0079] Non-limiting examples of biosurfactants include lipopeptides such as surfactin; fatty acids and phospholipids, polymeric matrix biosurfactants; particulate biosurfactants; and bacterial biosurfactants composed of polysaccharides, proteins, lipopolysaccharides, lipoproteins, or complex mixtures of these biopolymers.
[0080] Non-limiting examples of commercially available biosurfactants include alkyl polyglycoside available under the trademark EcoSense® 3000 from Dow Chemical®; D-glucopyranose, polymeric decyl octyl glycosides available under the trademark Glucopon® 215 from BASF Corporation®; rhamnolipids available under the trademark REWOFERM® SL ONE from Evonik®; D-Glucitol, l-deoxy-l-(methylamino)-, N-coco acyl derivatives available under the trademark GlucoTain® from Clariant®; rhamnolipids from Jeneil Biotech® and BioLoop® surfactants from Lankem® Ltd.
[0081] In one embodiment, the microbial biosurfactant is a glycolipid such as rhamnolipids (RLP), sophorolipids (SLP), trehalose lipid, or mannosylerythritol lipid (MEL). The biosurfactants may be added in purified form or may be present in the microbial-based composition due to microbial growth. The biosurfactant may be a sophorolipid. In some embodiments, the biosurfactant may also be a lipopeptide, such as surfactin, and / or a rhamnolipid.
[0082] In some embodiments, a mixture of biosurfactants is present. Preferably, the mixture comprises a rhamnolipid, and optionally one of a mannosylerythritol lipid, a surfactin, or a sophorolipid, or both. In a preferred embodiment, the microbe is a non-pathogenic strain of Pseudomonas . Preferably, the strain is a rhamnolipid biosurfactant (RLP) producer.
[0083] Other microbial strains including, for example, other fungal strains capable of accumulating significant amounts of, for example, glycolipid biosurfactants may be used in accordance with the subject invention. Biosurfactants useful according to the present invention include mannoprotein, beta-glucan and other metabolites which have bioemulsifying and surface / interfacial tension reducing properties.
[0084] In various embodiments, the one or more biosurfactants are selected from surfactin, iturin, fengycin, lichenysin, serrawettin, phospholipids, rhamnolipid, sophorolipid, trehalolipid, mannosylerythritol lipids, cellobiolipids, lipoproteins, rubiwettins, trehalose, omithine, pentasaccharide lipids, viscosin, bacitracin, lipopeptides, and combinations thereof. In one embodiment, the biosurfactants are selected from one or more glycolipids such as, for example, rhamnolipids, rhamnose-d-phospholipids, trehalose lipids, trehalose dimycolates, trehalose monomycolates, mannosylerythritol lipids, cellobiose lipids, ustilagic acid and / or sophorolipids.
[0085] In various embodiments, the biosurfactant has anionic character, for example, sophorolipids, trehalolipids and rhamnolipids. Mono-rhamnolipids and di-rhamnolipids are preferred. The preferred alkyl chain length is C8 to C12. The alkyl chain may be saturated or unsaturated.
[0086] The term “rhamnolipids” includes compounds of general formula (II) and their salts,
[0087] (II)
[0088] in which • mRL=2, 1 or 0, • nRL=l or 0, • R1rl and R2rl = are independently organic residues having 2 to 24, preferably 5 to 13 carbon atoms, in particular optionally mono-, bi- or tri-unsaturated, in particular optionally branched, optionally substituted, in particular hydroxy-substituted, optionally unsaturated alkyl residues, preferably those selected from the group consisting of pentenyl, heptenyl, nonenyl, undecenyl and tridecenyl and (CH2)o-CHs where o = 1 to 23, preferably 4 to 12.
[0089] If nRL=1, the glycosidic bond between the two rhamnose units is preferably in the α-configuration. The optically active carbon atoms of the fatty acids are preferably present as R-enantiomers (e.g. I-3-{L3-[2-O-(αL-rhamnopyranosyl)-αL-rhamnopyranosyl]oxydecanoyl]oxydecanoate).
[0090] The term "di-rhamnolipid" in the context of the present invention means compounds of the general formula (II) or their salts, where nRL=1.
[0091] The term "monorhamnolipid" in the context of the present invention means compounds of the general formula (II) or their salts, where nRL=0.
[0092] The distinct rhamnolipids are abbreviated according to the following nomenclature: "diRL-CXCY" means di-rhamnolipids of the general formula (II), in which one of the residues R1rl and R2rl = (CH2)o—CH3 where o=X-4 and the remaining residue R1 or R2 = (CH2) —CH3 where o=Y-4.
[0093] “monoRL-CXCY” means mono-rhamnolipids of the general formula (II), in which one of the residues R1rl and R2RL=(CH.sub.2).sub.o—CH.sub.3 where o=X-4 and the remaining residue R1rl or R2rl=(CH2)o—CH3 where o=Y-4. The nomenclature used therefore does not distinguish between “CXCY” and “CYCX”.
[0094] For rhamnolipids where mRL=0, monoRL-CX or diRL-CX is used accordingly.
[0095] If one of the above-mentioned indices X and / or Y is provided with ":Z", this means that the respective residue R1rl and / or R2rl is equal to an unbranched, unsubstituted hydrocarbon residue having carbon atoms X-3 or Y-3 having double bonds Z.
[0096] Methods for preparing the relevant rhamnolipids are disclosed, for example, in EP2786743 and EP2787065. Rhamnolipids can also be produced by fermentation of Pseudomonas, in particular Pseudomonas aeruginosa, which are preferably non-genetically modified cells, a technology already disclosed in the eighties, as documented for example in EP0282942 and DE4127908. Rhamnolipids produced in Pseudomonas aeruginosa cells that have been improved to obtain higher rhamnolipid titers by genetic modification can also be used in the context of the present invention; such cells have for example been disclosed by Lei et al. in Biotechnol Lett. 2020 Jun;42(6):997-1002. Biosurfactants, in particular glycolipid surfactants, can be produced, for example, as in EP 0 499 434, US Pat.No. 7,985,722, WO 03 / 006146, JP 60 183032, DE 19648439, DE 19600743, JP 01 304034, CN 1337439, JP 2006 274233, KR 2004033376, JP 2006 083238, JP 2006 070231, WO 03 / 002700, FR 2740779, DE 2939519, US Patent No. 7,556,654, FR 2855752, EP 1445302, JP 2008 062179 and JP 2007 181789.

[0100] In still other cases, a combination of acyl taurates and acyl isethionates may be used. Thus, the cleaning compositions may include two surfactants non-sulfate or more anionic surfactants comprising anionic surfactants selected from acyl taurates, acyl isethionates, or combinations thereof.
[0101] The total amount of the one or more anionic surfactants in the cleaning composition, if any, will vary but is typically in an amount of about 0.01 to about 10% by weight, based on the total weight of the cleaning composition.In other embodiments, the cleaning composition includes from about 0.01 to about 8 wt%, from about 0.01 to about 6 wt%, from about 0.01 to about 5 wt%, from about 0.01 to about 3 wt%, from about 0.1 to about 10 wt%, from about 0.1 to about 8 wt%, from about 0.1 to about 6 wt%, from about 0.1 to about 5 wt%, from about 0.1 to about 3 wt%, from about 0.5 to about 10 wt%, from about 0.5 to about 8 wt%, from about 0.5 to about 6 wt%, from about 0.5 to about 5 wt%, from about 0.5 to about 3 wt%, from about 1 to about 10 wt%, from about 1 to about 8% by weight, from about 1 to about 6% by weight, from about 1 to about 5% by weight, or from about 1 to about 3% by weight of the one or more anionic polymers, based on the total weight of the cleaning composition.

[0214] Droplet size can be determined using Brookhaven Dynamic Light Scattering (DLS). DLS is a technique used to determine droplet size in a colloidal system or emulsion. When samples are illuminated using a monochromatic laser beam, particles in the samples undergo Brownian motion, causing fluctuations in the scattered light intensity. The scattered light is then collected from different angles and the autocorrelation function of these intensity fluctuations is analyzed. The analysis provides information on the diffusion rate of particles, and from this, the size distribution is inferred using mathematical models. Brookhaven's DLS instruments use advanced algorithms to accurately interpret the data, providing insight into the dynamic behavior and size characteristics of particles ranging from a few nanometers to several micrometers in a liquid medium.

EXAMPLES
[0280] An implementation of the present disclosure is provided by means of the following examples. The following examples serve to explain certain aspects of the technology without being limiting in nature. Example 1
[0281] The compositions illustrated in the table below were prepared. The compositions were prepared by first mixing the MycelX®, m-rhamnolipid, sodium methyl cocoyl taurate and solvent (caprylic / capric triglyceride) with a small amount of water and mixing at 2500 rpm for 2 minutes at 25°C to form a homogeneous mixture. The homogeneous mixture was then diluted with additional water to form an oil-in-water emulsion.
[0282] [Tables 1] According to the invention Comparative INGREDIENTS AB MycelX®1 2.6 m-Rhamnolipid 3.2 3.2 Sodium cocoyl taurate 1.3 1.3 Caprylic / capric triglyceride 0.6 0.6 Water QS 100 100 Percentage of makeup removal 33% 32%
[0283] 1 Reaction product of linseed oil and isobutyl methacrylate polymer
[0284] A commercially available liquid foundation for application to the face was applied to an artificial skin model, i.e., to black soft substrates (Miyoshi, Japan). A 20 microliter amount of the liquid foundation was applied evenly to the substrates (20 microliters / 9 cm2). The liquid foundation was allowed to dry for 24 hours at 23-25 °C. After 24 hours, the L*a*b* values were determined for the soft substrates coated with makeup using a Datacolor 600™ Spectraflash spectrometer. The L values were recorded. The L value is a measure of the brightness of the sample. The higher the L value, the whiter / lighter the sample.
[0285] An amount of about 1.5 ml of the inventive cleaning composition A and the comparative composition B was applied to different cotton pads having a radius of about 2-3 cm. The black soft substrates coated with makeup were then wiped with the cotton pads. The wiping was carried out under pressure controlled using a pressure sensor control at a pressure of about 300 grams of force. After wiping, the black soft substrates were allowed to dry at 23-25 °C. Once dry, the L*a*b* values were again determined and the L values noted. When the makeup is removed, the black soft substrate is revealed, resulting in a lower L value. The foundation is lighter (higher L value) than the black soft substrates and therefore the more makeup on the substrate, the higher the L value. The percentage of foundation removal was determined as follows:
[0286] % elimination = (L before - L after ) / (L before L soft )
[0287] The results are reported in the table above and show that inventive composition A, which included MycelX®, provided greater removal of liquid foundation from black flexible substrates. Example 2
[0288] Inventive compositions C and D of the table below were prepared like the compositions of Example 1. The “reference” is a commercially available cleansing product intended for use in removing makeup from the skin.
[0289] [Tables2] According to the invention Reference INGREDIENTS CDE MycelX®1 2.6 2.6 2.6 m-Rhamnolipid 3.2 3.2 3.2 Sodium cocoyl taurate 1.3 1.3 1.3 Polycitronellol acetate 0.6 Isododecane 0.6 Water QS 100 100 100 Percentage of makeup removal 24% 25% 10%
[0290] 1 Reaction product of linseed oil and isobutyl methacrylate polymer
[0291] A commercially available liquid foundation for application to the face was applied to an artificial skin model, i.e., black soft substrates (Miyoshi, Japan). An amount of 20 microliters of liquid foundation (20 microliters / 9 cm2) was applied evenly to the surface of the substrates. The liquid makeup was allowed to dry on the black soft substrates for 24 hours at 23-25 °C. After 24 hours, the L*a*b* values were determined for the soft substrates coated with the dry makeup, using a Datacolor 600™ Spectraflash spectrometer. The L values were recorded. The L value is a measure of the brightness of the sample. The higher the L value, the whiter / brighter the sample.
[0292] An amount of about 1.5 ml of the inventive composition C or D, or the reference product, was applied to different cotton pads having a radius of about 2-3 cm. The black soft substrates coated with makeup were then wiped with the cotton pads. The wiping was carried out under pressure controlled using a pressure sensor control with a pressure of about 300 grams of force. After wiping, the black soft substrates were allowed to dry at 23-25 °C. Once dry, the L*a*b* values were again evaluated and the L values noted (more Makeup - higher L value). When the makeup is removed, the black soft substrate (low L value) is revealed, which results in a lower L value. The percentage of makeup removal from the substrates was determined as follows:
[0293] % elimination = (L before - L after ) / (L before L soft )
[0294] The results are reported in the table above and show that the inventive compositions C and D, which included MycelX®, provided significantly greater makeup removal than the commercial reference. Example 3 Foam reinforcement
[0295] Tests were carried out to determine how MycelX® influences foam formation. The composition presented below was prepared according to the inventive procedure described in Example 2, i.e. a first concentrated composition was prepared followed by dilution.
[0296] [Tables3] According to the invention Comp. INGREDIENTS 1 2 3 4 MYCELX®1 0.6 0.6 5.2 0 Rhamnolipid 0.7 0.7 5.7 0.7 SODIUM METHYL COCOYL TAURATE 0.3 0.3 2.3 0.3 polycitronellol acetate 0.1 caprylic / capric triglyceride 0.1 0.1 Initial foam volume (ml) 59.4 47.0 56.2 31.1 Final foam volume (ml) 47.8 38.0 40.1 26.6
[0297] 1 Reaction product of linseed oil and isobutyl methacrylate polymer
[0298] A Krüss Dynamic Foam Analyzer (DFA100) was used to measure the foamability of the compositions at a temperature of 25°C. The device uses a precisely controlled foaming process and an optical sensor that measures the amount (volume) of foam produced and the foam degradation characteristic, i.e., the foam durability. The results reported in the table above show that both the initial foam volume and the final foam volume were significantly higher for the inventive compositions containing MycelX®.
[0299] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.
[0300] The terms "a," "an," "the," and "the" are understood to encompass both the plural and the singular. Thus, the expression "a mixture thereof" also relates to "mixtures thereof." Throughout the disclosure, the expression "a mixture thereof" is used, after a list of elements as shown in the following example where the letters A through F represent the elements: "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture thereof." The expression "a mixture thereof" does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements selected from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E and F".
[0301] Similarly, the expression "a salt thereof" also relates to "salts thereof". Thus, when the disclosure refers to "a member selected from the group consisting of A, B, C, D, E, F, a salt thereof, and a mixture thereof", it indicates that one or more of A, B, C, D and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E and a salt of F may be included.
[0302] Salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is not limiting. Suitable counterions for the components described herein are known in the art.
[0303] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.
[0304] The term “plurality” means “more than one” or “two or more”.
[0305] The term "transparent" with respect to a transparent composition indicates that the composition has a transmittance of at least 80% at a wavelength of 600 nm, measured, for example, using a Lambda 40 UV-visible spectrometer. The compositions may have, for example, a transmittance of at least 80%, at least 90%, or at least 95% at a wavelength of 600 nm, measured, for example, using a Lambda 40 UV-visible spectrometer. The term "clear" is interchangeable with the term "transparent" for the purposes of this disclosure.
[0306] The term "translucent" in relation to a translucent composition indicates that the composition has a transmittance of at least 50% at a wavelength of 600 nm, measured for example using a Lambda 40 UV-visible spectrometer.
[0307] Except in the working examples, or if otherwise indicated, all numbers expressing amounts of ingredients and / or reaction conditions may be modified in all cases by the term "about", meaning to within + / - 5% of the number indicated. Thus, for a range of "about 1 to about 10% by weight", the lower amount of "about 1% by weight" may extend up to 0.95% by weight, i.e. 5% less than 1% by weight. The upper amount of "about 10% by weight" may be up to 10.5% by weight, i.e. 5% more than 10% by weight, i.e. a range of "0.95% by weight to 10.5% by weight".
[0308] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.
[0309] Some of the various categories of components identified may overlap. In such cases where an overlap may exist and the composition includes both components (or the composition includes more than two overlapping components), an overlapping compound does not represent more than one component. For example, some compounds may be considered both an oily solvent and a surfactant. If a particular composition includes both an oily solvent and a surfactant, a single compound will serve solely as the oily solvent or solely as the surfactant (the single compound does not simultaneously serve as both the oily solvent and the surfactant).
[0310] As used herein, all ranges provided are intended to include each specific range within the given ranges, as well as each combination of subranges therein. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc. All ranges and values disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein may serve as a minimum or maximum value to infer a subrange, etc.
[0311] The term "substantially free" or "essentially free" as used herein means that there is less than about 2% by weight of a specific material added to a composition, based on the total weight of the compositions. However, the compositions may include less than about 1% by weight, less than about 0.5% by weight, less than about 0.1% by weight, or none at all of the specified material. For example, if a composition is essentially free of compound X, the composition includes less than 2% by weight of compound X, or less than 1% by weight of compound X, or less than 0.5% by weight of compound X, or less than 0.1% by weight of compound X, or is free of compound X.
[0312] Any components positively presented in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are positively presented in the present disclosure.< / e>
