Description

Title of the invention: Cosmetic emulsion comprising a hydrophobic polymer FIELD OF DISCLOSURE

[0001] The present disclosure relates to cosmetic and personal care compositions in the form of oil-in-water emulsions containing a hydrophobic polymer formed as a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer. Methods of making the compositions and methods of using the compositions are also described. CONTEXT

[0002] Simple emulsions are dispersions of droplets of one liquid in another immiscible liquid. The droplets are generally formed by applied shear and stabilized against further coalescence by a surfactant that provides interfacial repulsion (J. Bibette, F. Leal-Calderon, and P. Poulin, Rep. Prog. Phys. 62, 969 (1999)). Two of the most common types are "direct" oil-in-water (O / W) emulsions and "reverse" water-in-oil (W / O) emulsions. Surfactants are amphiphilic molecules that can take many different forms, e.g., ionic (e.g., anionic, cationic, zwitterionic), nonionic (e.g., ethoxylated alkane chains), and polymeric (e.g., single, diblock, and triblock polymers). As they are amphiphilic, surfactants tend to adsorb preferentially on oil-water interfaces.The relative solubility of the surfactant in oil and water, the concentration of the surfactant, and the degree of interfacial repulsion that the surfactant provides once adsorbed onto the interfaces are important factors in determining the stability and longevity of emulsions.

[0003] In general, stable emulsion systems require the use of surfactants to reduce the surface energy at an interface between an aqueous phase and an oil phase. Many such surfactants, or emulsifiers, are known. Some types of emulsifiers, more than others, create more stable emulsions. For example, O / W emulsions achieve greater stability if the emulsifier is anionic, i.e., a lipophilic tail attached to a hydrophilic end group, the end group having a net negative charge. Multiple lipophilic tails surround and align in the direction of an oil droplet while the hydrophilic end groups extend into the continuous aqueous phase, away from the oil droplet. Thus, the outermost surface of the droplet complex is negatively charged. The droplets then repel each other and inhibit their coalescence, which would otherwise destabilize the emulsion.Cationic emulsifiers do not . are not generally used to stabilize an O / W emulsion. Nonionic emulsifiers can also be used to increase emulsion stability. Nonionic emulsifiers introduced into an emulsion by simple addition will migrate to the water-oil interface and reduce the interfacial energy, thus making the emulsion more stable. Low HLB nonionic emulsifiers generally stabilize W / O emulsions, while high HLB emulsifiers generally stabilize O / W emulsions.

[0004] The internal droplets do not share exactly the same diameter, but the emulsion can be characterized as a range of droplet sizes around an average diameter. Emulsions are classified somewhat imprecisely according to the internal phase droplet size and whether the emulsion is monodisperse or polydisperse (i.e., having one or more maximum droplet diameters). Microemulsions and nanoemulsions often use an aliphatic alcohol as a co-surfactant. The average oil droplet size in an O / W emulsion depends on the ratio of alcohol to another surfactant in the system. An increase in the alcohol / surfactant ratio can reduce the average oil droplet size, which also increases the dispersion of the oil droplets and the uniformity of the internal phase.

[0005] The use of an emulsion is essential in the cosmetic and personal care industry. The different phases of an emulsion effectively solubilize and transport different ingredients critical to the cosmetic product. Cosmetic compositions can be in the form of W / O or O / W emulsions, each with their own strengths and weaknesses. O / W emulsions have better mass / tone properties than W / O makeup emulsions. O / W emulsions are generally lighter, fresher, and less greasy. They also tend to be easier to remove. In addition, O / W systems generally have better breakup on the skin, meaning the composition spreads more easily and more evenly.On the other hand, W / O makeup emulsions have better or longer-lasting characteristics than O / W makeup emulsions, which often include a film-forming agent to improve their wearability. W / O makeup emulsions also tolerate humidity better than O / W emulsions.

[0006] There remains a need to produce stable, homogeneous cosmetic compositions having improved properties, for example, less sticky, less shiny and less greasy during and after application. This emulsion must be stable and retain its improved properties regardless of the addition of active ingredients.

[0007] Surprisingly, the inventors discovered that the hydrophobic polymer improves the stability, integrity and cosmetic properties of the emulsions formed with it. The resulting emulsions are homogeneous, stable and provide good sensory properties, for example, they are non-sticky, non-shiny and non-greasy on the skin and hair. They are therefore particularly useful for cosmetic and personal care products. SUMMARY OF DISCLOSURE

[0008] The present disclosure relates to stable oil-in-water emulsions particularly useful for cosmetic and personal care products. The emulsions include a single hydrophobic polymer, one or more surfactants, one or more oils capable of solubilizing the single hydrophobic polymer, and an aqueous phase composed predominantly of water. The emulsions are surprisingly robust, versatile, and useful for incorporating and delivering cosmetic ingredients, including skin and hair actives.

[0009] Emulsions, which are dispersions of one liquid phase in another, tend to become physically unstable due to causes such as creaming, sedimentation, flocculation, phase inversion, and coalescence. The tendency toward instability depends, at least in part, on the droplet size, droplet distribution, the amount and type of emulsifiers, and the mutual solubility of the two phases. Improved adsorption of the emulsifier results in a reduction in interfacial tension, lowers the free energy of the interface, and thus promotes emulsification and emulsion stability. The inventors have discovered that the unique hydrophobic polymers of the emulsions of the present disclosure positively influence (reduce) the interfacial tension between the oil droplets and the aqueous phase, contributing to a smaller droplet size and improved stability.

[0010] Oil-in-water compositions typically include: a. a hydrophobic polymer formed as a reaction product of a natural or food-derived oil and a methacrylate or acrylate polymer; b. one or more solvents capable of solubilizing the reaction product of (a); c. one or more surfactants; and d. water.

[0011] 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, 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, and combinations thereof. In a preferred embodiment, the hydrophobic polymer is formed from a natural or food-derived oil and an isobutyl methacrylate polymer.

[0012] 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 a linseed oil and a poly(isobutyl methacrylate) in a suitable solvent, such as, for example, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate.Preferably, the reaction product is formed from about 72 to about 77% of a linseed oil and about 23 to about 28% of an isobutyl methacrylate polymer in a suitable solvent, such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate.

[0013] One or more solvents capable of solubilizing the hydrophobic polymer of (a) may be a single solvent or a combination of solvents, wherein the combination of solvents is capable of solubilizing the hydrophobic polymer of (a). In various embodiments, the one or more solvents capable of solubilizing the hydrophobic polymer of (a) have a dispersion component (D), a polar component (P) and a hydrogen bonding component (H), and a distance (Ra), according to Hansen solubility parameters less than or equal to 13.4 MPa0'5, wherein (Ra) is defined by formula (I): [°°14] Ra = + (P - PJ2 + (H - ®

[0015] in which • Dr is 16.8 MPa0'5, • Pi is 4.8 MPa0'5, and • Hi is 13.0 MPa0'5.

[0016] 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. In some embodiments, polycitronellol acetate, Caprylic / capric triglyceride, isododecane, and their combinations are particularly useful.

[0017] Surfactants include anionic surfactants, cationic surfactants, amphoteric (zwitterionic) surfactants, and nonionic surfactants. In various embodiments, the compositions of the present disclosure include one or more anionic surfactants, and optionally one or more nonionic surfactants. Further, one or more of the surfactants may preferably 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. Rhamnolipids are particularly preferred.

In various embodiments, the compositions of the present disclosure include one or more acyl taurate surfactants.

[0019] The present disclosure also relates to methods of making emulsions. The methods involve producing an initial composition containing the hydrophobic polymer, one or more solvents capable of dissolving the hydrophobic polymer, and one or more surfactants, wherein the initial composition includes little or no water. Typically, the amount of water in the initial composition is from about 5 to about 40% by weight, based on the total weight of the initial composition. After forming a homogeneous initial composition, the initial composition is diluted with water or an aqueous phase, resulting in an emulsion. The emulsion forms surprisingly easily without requiring high energy or high shear mixing processes. For example, the emulsion can be formed by simply shaking or gently agitating the composition after dilution with water. DETAILED DESCRIPTION OF THE DISCLOSURE

[0020] The present disclosure relates to cosmetic or personal care compositions in the form of oil-in-water emulsions, to compositions used in preparing the oil-in-water emulsion, and to methods of making the oil-in-water emulsions. Methods of making and using the cosmetic and personal care compositions are also disclosed. The emulsions form the cosmetic or personal care compositions and are surprisingly robust, versatile, and useful for incorporating and delivering cosmetic ingredients, including active agents for skin and hair.

For example, the emulsion is formed simply by shaking the final composition or gently mixing the composition. The final composition is an oil-in-water emulsion. For example, in preferred embodiments, the emulsion includes:

[0024] (a) about 0.5 to about 10% by weight of a reaction product formed from of a natural or food-derived oil and a methacrylate or acrylate polymer;

The final emulsions are useful as cosmetic and personal care products and may be referred to as "emulsions," "cosmetic compositions," or "personal care compositions." Throughout the disclosure, when reference is made to "the composition," this means the final emulsion (the "cosmetic composition" or the "personal care composition") unless otherwise indicated. a. Hydrophobic polymer #

[0031] The hydrophobic polymer is a reaction product of a natural or food-derived oil (oil component) and an acrylate component. In particular, the natural or food-derived oil may be a drying oil, preferably linseed oil. The reaction product may 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 substances.

[0032] The hydrophobic polymer is composed of an oil component and a polymer component, generally 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.

[0033] The oily component is derived from glycerin and carboxylic acids, such as a flaxseed fatty acid, to form monoglycerides, diglycerides and triglycerides. The oily component is preferably of vegetable origin or of Natural. Vegetable oils are obtained by cold-pressing the seeds of a plant to obtain the oil they contain. Among 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).

[0034] 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, methyl methacrylic acid, or a combination thereof. 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. Preferably, the polymer is poly(isobutyl methacrylate).

[0035] The hydrophobic polymer is a reaction product generally formed in a liquid solvent capable of dissolving or diluting the polymer component and the resulting hydrophobic polymer. The solvent or diluent should generally include any liquid or mixture of liquids capable of dissolving or diluting the polymer and the resulting hydrophobic polymer. The solvent / diluent can control evaporation, desired flow rate, and coalescence of the hydrophobic polymer. The solvent can 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. Hydrophobic polymers according to the present disclosure and methods of making them are described, for example, in U.S. Pat.Nos. 5,437,793, 5,698,139, 5,837,146, 5,961,823, 6,180,010, 6,475,393 and 6,805,727. The preferred hydrophobic polymer may be designated as poly(linseed oil / isobutyl methacrylate).

[0036] The amount of hydrophobic polymer in the initial composition will vary. However, the total amount of the hydrophobic polymer in the initial composition is typically about 10 to about 40% by weight, based on the total weight of the initial composition. In another embodiment, the total amount of the hydrophobic polymer is about 10 to about 35% by weight, about 10 to about 30% by weight, about 15 to about 40% by weight, about 15 to about 35% by weight

The amount of hydrophobic polymer in the final emulsion will vary and depend on the amount of hydrophobic polymer used in the initial composition and the amount of water used to dilute the initial composition. However, in various embodiments, the total amount of hydrophobic polymer in the final emulsion is from about 0.1 to about 15% by weight, based on the total weight of the final emulsion. In other embodiments, the total amount of hydrophobic polymer in the final emulsion is from about 0.1 to about 12% by weight, from about 0.1 to about 10% by weight, from about 0.1 to about 8% by weight, from about 0.1 to about 5% by weight, from 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%, about 1 to about 5 wt%, about 1 to about 3 wt%, about 2 to about 15 wt%, about 2 to about 12 wt%, about 2 to about 10 wt%, about 2 to about 8 wt%, about 2 to about 5% by weight, relative to the total weight of the final emulsion. a.

[0050] The total amount of the one or more solvents capable of solubilizing the hydrophobic polymer of (a) in the initial composition will vary but may be from about 1 to about 99% by weight, based on the total weight of the initial composition.

Surfactant#

[0054] For the purposes of the present disclosure, the term "surfactant" includes emulsifiers and detergents. Surfactants are compounds that reduce the surface tension between two liquids or between a liquid and a solid. Surfactants are amphiphilic, meaning that they contain hydrophilic (water-loving) head groups and hydrophobic (water-unloving, oil-loving) tails. Surfactants adsorb at the interface between oil and water, thereby reducing the surface tension.

[0055] 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."

[0056] A “detergent” is a surfactant that has cleaning properties in dilute solutions and is generally anionic.

[0057] The surfactants may be anionic, cationic, amphoteric (zwitterionic), or nonionic surfactants. 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 free or essentially free of cationic surfactants. In other embodiments, the emulsions include one or more cationic surfactants. In a preferred embodiment, the emulsions include one or more biosurfactants. In another preferred embodiment, the emulsions contain one or more biosurfactants, one or more anionic surfactants, optionally one or more non-ionic surfactants, or mixtures thereof.

[0058] 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.

[0059] The total amount of the one or more surfactants in the initial composition will vary but is typically from about 10 to about 65% by weight, based on the total weight of the initial composition.In other embodiments, the total amount of one or more surfactants is about 20 to about 55 wt%, about 20 to about 50 wt%, about 20 to about 45 wt%, about 25 to about 60 wt%, about 25 to about 55 wt%, about 25 to about 50 wt%, about 25 to about 45 wt%, about 30 to about 60 wt%, about 30 to about 55 wt%, about 30 to about 50 wt%, about 30 to about 45 wt%, about 35 to about 60 wt%, about 35 to about 55 wt%, about 35 to about 50 wt%, about 35 to about 45 wt% by weight, from about 40 to about 60% by weight, from about 40 to about 55% by weight, from about 40 to about 50% by weight, or from about 40 to about 45% by weight, relative to the total weight of the initial composition.

[0060] The total amount of the one or more surfactants in the final emulsion will vary but is typically from about 0.5 to about 20% by weight. In other embodiments, the total amount of the one or more surfactants in the final emulsion 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 about 6% by weight, about 3 to about 20% by weight, about 3 to about 15% by weight, 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 or from about 4 to about 6% by weight, based on the total weight of the final composition. Biosurfactant

[0061] The compositions of the present disclosure may include one or more biosurfactants. The biosurfactants are amphiphilic molecules, for example, 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.

[0062] 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 agents for stabilizing emulsions. 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 portions. Examples of high molecular weight biosurfactants include polysaccharides, lipopolysaccharides, proteins, and lipoproteins.A polysaccharide-based biosurfactant can be classified into sorbitan esters, sucrose esters, and glucose-based surfactants which include alkylpolyglycosides and fatty acid glucamides.

[0063] Non-limiting examples of biosurfactants include lipopeptides such as surfactin; fatty acids and phospholipids, polymer matrix biosurfactants; particulate biosurfactants; and bacterial biosurfactants composed of polysaccharides, proteins, lipopolysaccharides, lipoproteins, or complex mixtures of these biopolymers.

[0064] Non-limiting examples of commercially available biosurfactants include alkyl polyglycoside available under the trademark EcoSense® 3000 from Dow Chemical®; D-glucopranose, oligomeric, decyl octyl glycosides available under the trade name Glucopon® 215 from BASF Corporation®; rhamnolipids available under the trade name REWOFERM® SL ONE from Evonik®; D-Glucitol, l-deoxy-l-(methylamino)-, N-coco acyl derivatives available under the trade name GlucoTain® from Clariant®; rhamnolipids from Jeneil Biotech® and BioLoop® surfactants from Lankem® Ltd.

[0065] 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.

[0066] In some embodiments, a mixture of biosurfactants is present. Preferably, the mixture comprises a rhamnolipid, and optionally one or both of a mannosylerythritol lipid, a surfactin, or a sophorolipid. In a preferred embodiment, the microbe is a non-pathogenic strain of Pseudomonas. Preferably, the strain is a rhamnolipid biosurfactant (RLP) producer.

[0067] 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 present invention. Biosurfactants useful according to the present invention include mannoprotein, beta-glucan and other metabolites that exhibit bioemulsifying and surface / interfacial tension reducing properties.

[0068] 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.

[0069] In various embodiments, the biosurfactant has an anionic character, for example, sophorolipids, trehalolipid 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.

[0070] The term “rhamnolipids” includes compounds of general formula (II) and their salts,

[0071] in which • mRL = 2, 1 or 0, • nRL = 1 or 0, • R1rl and R2rl = are independently organic residues having 2 to 24, preferably 5 to 13 carbon atoms, in particular optionally branched, optionally substituted, in particular hydroxy-substituted, optionally unsaturated, in particular optionally mono-, bi- or tri-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.

[0072] 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).

[0073] The term "di-rhamnolipid" in the context of the present invention means compounds of the general formula (II) or their salts, where nRL=1.

[0074] The term "monorhamnolipid" in the context of the present invention means compounds of general formula (II) or their salts, where nRL=0.

[0075] The distinct rhamnolipids are abbreviated according to the following nomenclature: "diRL-CXCY" means the di-rhamnolipids of the general formula (II), in which one residues R1rl and R2rl=(CH2)o—CH3 where o=X-4 and the remaining residue R1 or R2=(CH2)O —CH3 where o=Y-4.

[0076] “monoRL-CXCY” means mono-rhamnolipids of 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”.

[0077] For rhamnolipids where mRL=0, monoRL-CX or diRL-CX is used accordingly.

[0078] 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 X-3 or Y-3 carbon atoms having Z double bonds.

[0079] Methods for preparing suitable rhamnolipids are disclosed, for example, in EP2786743 and EP2787065. Rhamolipids 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 increase 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. Jun 2020;42(6):997-1002.

[0196] (i) Polyurethanes

[0197] The polyurethanes may be aliphatic, cycloaliphatic or aromatic copolymers, polyurea-urethanes or polyurea copolymers, comprising, alone or as a mixture: at least one block of aliphatic and / or cycloaliphatic and / or aromatic polyester origin, and / or at least one branched or unbranched silicone block branched, for example polydimethylsiloxane or polymethylphenylsiloxane, and / or at least one block comprising fluoro groups.

[0198] The film-forming polyurethanes which can be used in the invention can also be obtained from branched or unbranched polyesters or from alkyls comprising labile hydrogens, which are modified by reaction with a diisocyanate and a difunctional organic compound (e.g. dihydroxy, diamino or hydroxyamino), also comprising either a carboxylic acid or carboxylate group, or a sulfonic acid or sulfonate group, or alternatively a neutralizable tertiary amine group or a quaternary ammonium group.

[0203] (ii) Vinyl polymers

[0204] The vinyl polymers may be chosen from polyvinyl alcohols, copolymers derived from C4-C8 monounsaturated carboxylic acids or anhydrides, and methyl vinyl ether / butyl monomaleate copolymers. For the purposes of the present invention, the term "polyvinyl alcohol" denotes a polymer comprising -CH2CH(OH)- units. Polyvinyl alcohols are generally produced by hydrolysis of polyvinyl acetate. Usually, the reaction occurs in the presence of methanol (alcoholysis). The reaction is normally catalyzed by acid or base catalysis. The degree of hydrolysis of commercial products is variable, often around 87%, but products with a degree of hydrolysis of 100 also exist. There are also copolymers with monomers other than vinyl acetate, such as ethylene / vinyl alcohol copolymers.

[0205] The polyvinyl alcohol polymers are preferably chosen from homopolymers or copolymers with vinyl acetate, the latter corresponding in particular to a partial hydrolysis of polyvinyl acetate.

[0206] For example, it is possible to use the products from the Celvol range supplied by the company Cenese under the names Celvol 540, Celvol 350, Celvol 325, Celvol 165, Celvol 125, Celvol 540 S, Celvol 840 and Celvol 443.

Preferably, the copolymer(s) derived from C4-C8 monounsaturated carboxylic acids or anhydrides is / are chosen from monoesterified methyl vinyl ether / maleic anhydride copolymers, for example, the ethyl ester of PVM / MA copolymer, sold under the name Gantrez ES 225 by the company ISP.

[0208] (iii) Natural polymers

[0209] The polymers may also be chosen from natural polymers, in particular polysaccharides which have monosaccharides or disaccharides as basic units. The natural polymers are preferably chosen from pullulan, guar gums and modified guar gums, celluloses and gellan gum, and their derivatives.

[0210] In a preferred embodiment, a natural film-forming polymer is pullulan. Pullulan is a polysaccharide polymer consisting of maltotriose units, also known as 'α-1,4-;α1,6-glucan'. Three glucose units in maltotriose are connected by an α-1,4 glycosidic linkage, while consecutive maltotriose units are connected to each other by an α-1,6 glycosidic linkage. In various embodiments, the skin-perfecting compositions include pullulan and optionally one or more additional film-forming polymers, e.g., one or more polyurethanes. In this situation, the amount of pullulan will vary.

[0211] Guar gums are galactomannans consisting of mannose and galactose. For the purposes of the present disclosure, the term "modified guar gum" means alkylated guar gums with at least one C1-C8 alkyl group, hydroxy alkylated guar gums with at least one C1-C8 hydroxyalkyl group, and alkylated guar gums with at least one C1-C8 acyl group. Hydroxypropylated guar gums (e.g., hydroxypropyl guar) such as the product sold under the name Jaguar HP 105 by Rhodia are a useful example.

[0212] Cellulose is a [31-4-polyacetal of cellobiose, cellobiose being a disaccharide consisting of two glucose molecules. Cellulose derivatives may be cationic, amphoteric, or non-ionic. These derivatives include cellulose ethers, cellulose esters, and cellulose ester ethers. Non-ionic cellulose ethers include alkylcelluloses such as methylcelluloses and ethylcelluloses; hydroxyalkylcelluloses, such as hydroxymethylcelluloses, hydroxyethylcelluloses, and hydroxypropylcelluloses; and mixed hydroxyalkylcelluloses such as hydroxypropylmethylcelluloses, hydroxyethylmethylcelluloses, hydroxyethylethylcelluloses, and hydroxybutylmethylcelluloses.

[0213] Among the cationic cellulose ethers, mention may be made of crosslinked or non-crosslinked quaternized hydroxyethylcelluloses. The quaternizing agent may in particular be glycidyltrimethylammonium chloride or a fatty amine such as laurylamine or stearylamine. Another cationic cellulose ether that may be mentioned is hydroxypropyltrimethylammonium hydroxyethylcellulose. Among the cellulose esters are inorganic cellulose esters (cellulose nitrates, sulfates, phosphates, etc.), organic cellulose esters (cellulose monoacetates, triacetates, amidopropionates, acetate butyrates, acetate propionates and acetate trimellitates, etc.) and mixed organic / inorganic cellulose esters, such as cellulose acetate butyrate sulfates and cellulose acetate propionate sulfates.

[0214] Among the cellulose ester ethers, mention may be made of hydroxypropylmethylcellulose phthalates and ethylcellulose sulfates. The cellulose-based compounds of the invention may be chosen from unsubstituted celluloses and substituted celluloses.

[0215] Celluloses and derivatives are represented, for example, by the products sold under the names Avicel® (microcrystalline cellulose, MCC) by the company FMC Biopolymers, under the names MethocelTM (cellulose ethers) and Ethocel™ (ethylcellulose) by the company Dow, Benecel® (methylcellulose), Blanose™ (carboxymethylcellulose), Culminai® (methylcellulose, hydroxymethylcellulose), Klucel® (hydroxypropylcellulose), Polysurf® (cetylhydroxyethylcellulose) and Natrosol® CS (hydroxyethylcellulose) by the company Hercules Aqualon.

[0216] Gellan gum is a polysaccharide produced by aerobic fermentation of Sphingomonas elodea, more commonly known as Pseudomonas elodea. This linear polysaccharide is formed from the sequence of the following monosaccharides: D-glucose, D-glucuronic acid and L-rhamnose. In its native form, gellan gum is highly acylated. The gellan gum preferably used in the film according to the present invention is a gellan gum which is at least partially deacylated. This at least partially deacylated gellan gum is obtained by alkaline treatment at high temperature. For example, a KOH or NaOH solution will be used. The purified gellan gum sold under the trade name Kelcogel® by the company Kelco is suitable for the preparation of the compositions according to the invention.

[0217] Gellan gum derivatives are all products obtained by carrying out standard chemical reactions, in particular esterifications, the addition of a salt of an organic or mineral acid. Welan gum is for example used as a gellan gum derivative. Welan gum is a gellan gum modified by fermentation using the strain Alcaligenes ATCC 31 555. Welan gum has a recurring pentasaccharide structure formed by a main chain composed of D-glucose, D-glucuronic acid and L-rhamnose units, onto which a pendant L-rhamnose or L-mannose unit is grafted. Welan gum (diutan gum) sold under the trade name Kelco Crete® by the company Kelco is suitable for the preparation of the compositions according to the invention.

[0218] As other saccharide polymers which can be used according to the invention, mention may be made of starches and their derivatives.

[0219] Natural film-forming polymers include celluloses and their derivatives, in particular those sold under the name Avicel® (microcrystalline cellulose, MCC) by the company FMC Biopolymers.

[0220] Carrageenans are anionic polysaccharides constituting the cell walls of various red algae (Rhodophyceae) belonging to the families Gigartinaceae, Hypneaceae, Furcellariaceae and Polyideaceae. They are generally obtained by hot aqueous extraction from natural strains of said algae. These linear polymers, formed by disaccharide units, are composed of two D-galactopyranose units linked alternately by α(1,3) and β(1,4) bonds. They are highly sulfated polysaccharides (20% to 50%) and the α-D-galactopyranosyl residues can be in 3,6-anhydro form. Depending on the number and position of sulfate ester groups on the repeating disaccharide of the molecule, several types of carrageenans are distinguished, namely: kappa-carrageenans, which carry one sulfate ester group, iota-carrageenans which carry two groups sulfate ester, and lambda-carrageenans which carry three sulfate ester groups. Carrageenans are composed primarily of potassium, sodium, magnesium, triethanolamine and / or calcium salts of polysaccharide sulfate esters.

[0221] Carrageenans are sold in particular by the company SEPPIC under the name Solagum®, by the company Gelymar under the names Carragel®, Carralact® and Carrasol®, by the company Cargill under the names Satiagel™ and Satiagum™, and by the company CP-Kelco under the names Genulacta®, Genugel® and Genuvisco®.

[0223] A useful film-forming polymer is xanthan gum and modified xanthan gums, such as dehydroxanthan gum, hydroxypropyl xanthan gum, and mixtures thereof. In some cases, dehydroxanthan gum is useful.

[0224] (iv) Latex or pseudolatex polymers

[0225] As presented above for film-forming polyurethanes, the film-forming polymer may therefore also be present in a composition of the invention in the form of particles dispersed in an aqueous phase, generally known as latex or pseudolatex. The techniques for preparing these dispersions are well known to those skilled in the art.

Various ingredients

[0231] The compositions and emulsions of the present disclosure may optionally include one or more miscellaneous ingredients. Miscellaneous ingredients are ingredients that are compatible with the compositions and emulsions and do not disrupt or materially affect the fundamental and novel properties. Non-limiting examples of ingredients include preservatives, fragrances, pH adjusters, salts, chelating agents, buffers, antioxidants, flavonoids, vitamins, botanical extracts, UV filtering agents, proteins, protein hydrolysates and / or isolates, fillers (e.g., organic and / or inorganic fillers such as talc, calcium carbonate, silica, etc.), composition colorants, etc. In various embodiments, the miscellaneous ingredients are selected from preservatives, fragrances, pH adjusters, salts, chelating agents, buffers, composition colorants, and mixtures thereof.In the context of this disclosure, a "composition colorant" is a compound that colors the composition, but does not have an appreciable coloring effect on the hair. In other words, the composition colorant is included to impart coloring to the composition for aesthetic purposes but is not intended to impart coloring properties to the hair. Hair styling gels, for example, can come in a variety of different colors (e.g., light blue, light pink, etc.), but applying the styling gel to the hair does not visibly change the color of the hair.

[0232] The total amount of the one or more miscellaneous ingredients in the initial composition, if any, will vary. However, in various embodiments, the composition initial includes about 0.1 to about 15% by weight of the one or more miscellaneous ingredients, based on the total weight of the compositions. In other embodiments, the composition includes about 0.1 to about 12 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 5 wt.%, 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 1 to about 15 wt.%, about 1 to about 12 wt.%, about 1 to about 10 wt.%, about 1 to about 8 wt.%, about 1 to about 5 wt.%, about 2 to about 15 wt.%, about 2 to about 12 wt.%, about 2 to about 10 wt.%, from about 2 to about 8% by weight, or from about 2 to about 5% by weight relative to the total weight of the initial composition.

[0233] The total amount of the one or more miscellaneous ingredients in the final emulsion, if any, will vary. However, in various embodiments, the final emulsion includes about 0.1 to about 15 wt.% of the one or more miscellaneous ingredients, based on the total weight of the compositions. In other embodiments, the final emulsion includes about 0.1 to about 12 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 5 wt.%.%, 0.5 to about 15% by weight, from about 0.5 to about 12% by weight, from about 0.5 to about 10% by weight, from about 0.5 to about 8% by weight, from about 0.5 to about 5% by weight, from about 1 to about 15% by weight, from about 1 to about 12% by weight, from about 1 to about 10% by weight, from about 1 to about 8% by weight, from about 1 to about 5% 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, or from about 2 to about 5% by weight, based on the total weight of the final emulsion. Droplet size

[0234] In various embodiments, the average droplet size is from about 10 nm to about 2 pm, from about 10 nm to about 1.5 pm, from about 10 nm to about 1 pm, from about 10 nm to about 800 nm, from about 10 nm to about 600 nm, from about 10 nm to about 500 nm, from about 10 nm to about 250 nm, from about 50 nm to about 2 pm, from about 50 nm to about 1.5 pm, from about 50 nm to about 1 pm, from about 50 nm to about 800 nm, from about 50 nm to about 600 nm, from about 50 nm to about 500 nm, from about 50 nm to about 250 nm, from about 100 nm to about 2 pm, from about 100 nm to about 1.5 pm, from about 100 nm to about 1 pm, from about 100 nm to about 800 nm, from about 100 nm to about 600 nm, from about 100 nm to about 500 nm, from about 100 nm to about 300 nm, from about 150 nm to about 500 nm, from about 150 nm to about 400 nm, from about 200 nm to about 500 nm, or from about 200 nm to about 300 nm.

[0235] 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 with a monochromatic laser beam, the particles in the samples undergo Brownian motion, which causes fluctuations in the intensity of the scattered light. The scattered light is then collected at different angles and the autocorrelation function of these intensity fluctuations is analyzed. The analysis provides information on the diffusion rate of the particles, from which the size distribution is inferred using mathematical models.Brookhaven's DLS instruments use advanced algorithms to accurately interpret data, providing insights into the dynamic behavior and size characteristics of particles ranging from a few nanometers to several micrometers in a liquid medium.

[0300] 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 Standard preparation process

[0301] Three emulsions (A, B and C) were prepared according to a standard procedure known in the art of emulsion preparation. The ingredients were directly combined, without first solubilizing the Mycelx® in a solvent and surfactants. The compositions were processed using a high-speed Silverson homogenizer capable of generating fine droplet sizes in the range of 2 to 5 microns. Despite subjecting the compositions to the high-speed homogenization process, the droplet size of the resulting emulsions was larger than 1 micron, the compositions were not transparent, and the compositions phase separated at 45 °C.

[0304] After the formation of the emulsions, the compositions were further diluted at a ratio of 1:100 with water and the droplet size was measured by Brookhaven dynamic light scattering (DLS). DLS is a technique used to determine the droplet size in a colloidal system or emulsion. A Brookhaven instrument was used to determine the particle size distribution of each sample. When the samples are illuminated with a monochromatic laser beam, the particles in the samples undergo Brownian motion, which causes fluctuations in the intensity of the scattered light. The scattered light is then collected at different angles and the autocorrelation function of these intensity fluctuations is analyzed. The analysis provides information on the diffusion rate of the particles, from which the size distribution is inferred using mathematical models. Brookhaven's DLS instruments use advanced algorithms to accurately interpret the data, providing information on the dynamic behavior and size characteristics of particles ranging from a few nanometers to several micrometers in a liquid medium. Example 2 Process of preparing the invention

[0305] Three initial compositions (D(i), E(i), and F(i)) were prepared by mixing m-rhamnolipid, sodium methyl cocoyl taurate and MycelX®, a solvent (caprylic / capric triglyceride, polycitronellol acetate, isododecane) and water in the amounts indicated in the table below at 2500 rpm for 2 minutes at 25°C. The compositions were homogeneous.

[0308] The initial compositions of Example 2 ((D(i), E(i), and F(i), were processed to generate dispersions (D, E and F). The initial compositions of Example 2 were diluted with water and gently mixed to generate dispersions. The dispersions form without the need for high-speed mixers or other energy-intensive procedures. The gentle mixing used to generate the dispersions consisted of simply shaking the compositions to uniformly mix the base compositions with additional water.

[0311] After forming the dispersions (D, E and F), they were diluted in a ratio of 1:100 with water and the droplet size was measured using Brookhaven Dynamic Light Scattering (DLS). DLS is a technique used to determine the droplet size in a colloidal system or emulsion. A Brookhaven instrument was used to determine the particle size distribution of the particles in each sample.

Example 4 Interfacial tension

[0312] Studies were conducted to determine how MycelX® contributes to the interfacial tension of the oil phase using droplet shape analysis with a Biolab optical tensiometer. The procedure involves capturing and analyzing the shape of a liquid droplet formed at the interface between two immiscible fluids. The Biolab optical tensiometer uses advanced optical techniques to accurately capture the droplet shape, and the interfacial tension is calculated based on the geometric parameters of the droplet. In the process of measuring interfacial tension using droplet shape analysis with a Biolab optical tensiometer, a small droplet of one liquid (Mycelx® and oil) is distributed on the surface of another immiscible liquid (water and surfactant or only water), forming an interface.The Biolab optical tensiometer captures high-resolution images of the droplet, and the system's software accurately analyzes the droplet's contour. This involves extracting key geometric parameters, such as droplet diameter and height. Interfacial tension is then calculated using the Young-Laplace equation, which correlates the pressure difference across the curved interface with the droplet shape and interfacial tension. This process provides a non-invasive and efficient way to determine interfacial tension, providing valuable information on the surface properties of liquids and helping to characterize materials in various industries. The results are shown in the table below.

[0314] 1 Reaction product of linseed oil and isobutyl methacrylate polymer.

[0315] The results indicate that MycelX® contributes to ultra-low interfacial tension resulting in the formation of dispersions with very small droplet sizes. This is evident from the data in Example 1, which shows that surfactants alone are not capable of producing the dispersions. MycelX® interacts with the surfactants and reduces the interfacial tension, which allows for a smaller droplet size. The lower the interfacial tension, the smaller the dispersed droplet size. Interfacial tension is like a “tug of war” between the interphase of the oil phase and the aqueous phase. It is the force that prevents the two phases from mixing easily. The unit of interfacial tension is generally measured in millinewtons per meter (mN / m) or dynes per centimeter (dyn / cm).The higher the interfacial tension, the less likely it is that an oil phase and an aqueous phase will mix easily, resulting in larger droplet sizes and less stable emulsions. Example 5 Foam Reinforcing Properties

[0316] Tests were carried out to determine how MycelX® influences foam formation and durability. The emulsions shown in the table below were prepared according to the procedure described in Example 2, i.e., the initial compositions were first prepared and then diluted to form the emulsions.

[0318] 1 Reaction product of linseed oil and isobutyl methacrylate polymer.

[0319] A Krüss Dynamic Foam Analyzer (DFA100) was used to measure the foamability of the compositions at a temperature of 25°C. The apparatus uses a precisely controlled foaming process and optical sensor that measure the amount (volume) of foam produced and the foam disintegration 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®.

[0320] The data shows that in addition to the astonishing stability and droplet size reduction provided by MycelX®, MycelX® also provides an unexpected improvement in foam formation and longevity.

[0321] The foregoing description illustrates and describes the disclosure. Furthermore, the disclosure shows and describes only the preferred embodiments. However, as mentioned above, it is to be understood that it is capable of use in many other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concepts as expressed herein, consistent with the above teachings and / or the skill or knowledge of the relevant art. The embodiments described herein are further intended to explain the best modes known to the applicant and to enable others skilled in the art to use the disclosure in such or other embodiments and with the various modifications required by the particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein.The appended claims are also intended to be construed as including other embodiments.

[0322] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.

[0323] 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 to 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 the elements 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."

[0324] Similarly, the expression "one of their salts" also relates to "their salts". Thus, when the disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, one of their salts, 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.

[0325] 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.

[0326] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.

[0327] The term “plurality” means “more than one” or “two or more.”

[0328] 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.

[0329] 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.

[0330] Except in the working examples, or unless 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, which is 5% less than 1% by weight. The upper amount of "about 10% by weight" may be up to 10.5% by weight, which is 5% more than 10% by weight, i.e., a range of "0.95% by weight to 10.5% by weight".

[0331] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.

[0332] 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).

[0333] 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 derive a subrange, etc.

[0334] The term "substantially free" or "essentially free" as used herein means that less than about 2% by weight of a specific material is 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.

[0335] 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.
