Description
Title of the invention: Cosmetic composition comprising a cutaneous active agent FIELD OF DISCLOSURE
[0001] The present disclosure relates to cosmetic compositions in the form of oil-in-water emulsions comprising a hydrophobic polymer and one or more skin active agents. Methods of manufacturing the composition and methods of treating the skin are also disclosed. CONTEXT
[0002] The skin is a unique and complex organ that extends throughout the body. It is essential for protecting the body from external threats, regulating body temperature, and preventing moisture loss. It also serves as a sensory organ and produces vitamin D. There are different types of skin in different parts of the body. For example, the skin on the face is different from that of the scalp, and even the skin on the palm of the hand is different from the skin on the back of the hand.
[0003] The skin constitutes the integumentary system which includes three layers: the epidermis, the dermis and the hypodermis. The epidermis is the outermost layer of the skin and the first line of defense against external threats, such as microbes. The human epidermis is primarily composed of keratinocytes containing other cell types, including melanocytes and Langerhans cells. Each of these cell types contributes, through its specific function, to the essential role played by the skin. Melanocytes impart a characteristic color and tone to the skin. The epidermis is essentially impermeable to water and therefore helps maintain hydration and prevents the body from absorbing water when bathing. Unlike other cells, epidermal cells have a unique ability to regenerate and can therefore heal after being injured.
[0004] The middle layer of the skin that lies just beneath the epidermis is the dermis, which includes connective tissue, collagen, elastin, hair follicles, lymph nodes, and sweat glands. The dermis provides strong support to the epidermis. It is also its nourishing layer. The dermis primarily includes fibroblasts, but leukocytes, mast cells, or tissue macrophages are also present. The dermis also contains blood vessels and nerve fibers. The acellular portion (i.e., the area between the cells) of the dermis is called the extracellular matrix. The extracellular matrix of the skin is composed of various extracellular components, including proteins, especially collagen fibers, and elastin. Other components of the extracellular matrix of the skin include glycosaminoglycans (e.g., hyaluronic acid, chondroitin sulfate, dermatan sulfate, keratan sulfate, heparan sulfate, etc.), proteoglycans (e.g., fibromodulin, decorin, biglycan, perlecan, heparan sulfate proteoglycan 2, agrin, versican, aggrecan, lumican, collagen type IX, collagen type XII, collagen type XIV, testican 1, testican 2, etc.), and various glycoproteins (e.g., fibrillin 1, thrombospondins-1 and -2, tenascins-C and -X, osteopontin, fibronectin, laminins-5 and -6, vitronectin, etc.). These extracellular components are synthesized by dermal fibroblasts, making dermal fibroblasts the main constituent of the structural assembly of the dermis.
[0005] The extracellular matrix is a highly heterogeneous amalgam of morphologically diverse architectural entities. It organizes and confers structural integrity to individual tissues, in addition to modulating cellular behavior by interacting with cell surface receptors and soluble growth factors. Dysfunctions and changes in extracellular matrix components can therefore interfere with both tissue integrity and cellular performance. Dysfunctions and changes in extracellular matrix components of skin and mucosa in humans can lead to skin aging, skin atrophy, skin lesions, skin wounds, and other problems.
[0006] The hypodermis is the deepest layer of the skin and is composed primarily of fatty and connective tissue. It connects the skin to the underlying fascia (tissue) of bones and muscles. The hypodermis is not always classified as an official layer of the skin, but it nevertheless provides important functions such as energy storage, body insulation, and prevention of skin sagging. The hypodermis houses fat storage cells that act as energy reservoirs and act as a cushion against impacts.
[0007] Over time, the skin ages, which can lead to wrinkles, brown spots, and a loss of elasticity and volume. Skin aging includes both chronological aging (endogenous aging), which is natural aging that occurs over time due to natural biological processes, and degenerative aging due to external influences, such as exposure to harmful sunlight, pollution, lack of hydration, etc. Ultraviolet rays, such as UVB, have a wavelength in the range of 280 nm to 320 nm and are known to damage the skin and accelerate aging. UVB rays stimulate reactive oxygen species (ROS) and free radicals in skin cells, which accelerates the intracellular signaling system and induces oxidative stress on biomolecules, such as DNA, proteins, and lipids. Increased oxidative stress in skin cells can cause stimulation of epidermal keratinocytes or dermal fibroblasts and, through a series of intracellular signal transduction, the expression of genes such as matrix metalloproteinase (MMP), a collagen-degrading enzyme, can increase.
[0008] There are many treatments available to treat the skin. For example, the importance of collagen in the aging process has led to the development of many topical products containing collagen. Other components, such as retinoic acid, vitamin C, and hyaluronic acid, are used in topical formulations to stimulate collagen synthesis. Some cosmetic procedures, such as laser skin resurfacing, are used to reduce facial wrinkles and skin irregularities. Topical administration of proteins known to inhibit one or more signaling pathways that exhibit altered activity after UV exposure has been explored. However, there are difficulties associated with the use of whole proteins that cannot be effectively delivered via the epidermis.Furthermore, large proteins can be unstable, difficult to formulate, and ineffective topically. Despite the number of products and treatments that have been proposed, none of them satisfactorily elicit the skin's intrinsic repair and regeneration mechanisms. SUMMARY OF DISCLOSURE
[0009] The present disclosure relates to cosmetic compositions in the form of oil-in-water dispersions. The compositions effectively incorporate and deliver skin active agents to the skin. This is achieved, at least in part, through the inclusion of a unique hydrophobic polymer, which is solubilized in an oil or oil phase. The hydrophobic polymer helps stabilize the dispersion, reduces the size of the oil droplets, and improves the penetration of the skin active agents into the skin. Skin active agents can be difficult to formulate into cosmetic compositions and deliver into the skin. For example, many skin active agents suffer from solubility and stability issues. Even if skin active agents are successfully formulated for stability, a stable formulation does not necessarily ensure that the skin active agents will penetrate the skin.However, the oil-in-water emulsions in the present case are both stable and effective in delivering skin active agents deep into the skin.
[0010] Oil-in-water dispersions can 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 droplet size, droplet distribution, and the amount and type of emulsifiers. and mutual solubility between the phases. Improved adsorption of the emulsifier leads to a reduction in interfacial tension, lowers the interface free energy and thus promotes emulsification and emulsion stability. The inventors have discovered that the unique hydrophobic polymers of the present emulsions positively influence (reduce) interfacial tension and contribute to a robust and stable cosmetic composition that successfully incorporates and delivers skin active agents in large quantities.
[0011] The cosmetic composition is an oil-in-water emulsion comprising: 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 cutaneous active agents; d. one or more surfactants; and e. water.

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.

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.

In one embodiment Preferably, the hydrophobic polymer is a reaction product of a linseed oil and a poly(isobutyl methacrylate), reacted in a solvent, such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate as a solvent.
[0032] The oil component is derived from glycerin and carboxylic acids, such as a flaxseed fatty acid, to form monoglycerides, diglycerides, and triglycerides. The oil component is preferably of plant origin or naturally occurring origin. Vegetable oils are obtained by cold pressing the seeds of a plant to obtain the oil 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).

For example, the one or more solvents capable of solubilizing the hydrophobic polymer of (a) may be in amounts of about 10 to about 70% by weight, based on the total amount of the cosmetic composition.In other embodiments, the total amount of the one or more solvents capable of solubilizing the hydrophobic polymer may be in amounts of about 10 to about 60 wt%, about 10 to about 50 wt%, about 10 to about 40 wt%, about 10 to about 30 wt%, about 20 to about 70 wt%, about 20 to about 60 wt%, about 20 to about 50 wt%, about 20 to about 40 wt%, about 30 to about 70 wt%, about 30 to about 60 wt%, about 30 to about 50 wt%. weight, from about 30 to about 40% by weight, from about 40 to about 70% by weight, from about 40 to about 60% by weight, or from about 40 to about 60% by weight, based on the total weight of the cosmetic composition.
[0051] The oil-in-water emulsions forming the cosmetic composition do not require a high amount of an oil phase, which is dispersed in droplets throughout the aqueous phase. Thus, in various embodiments, the cosmetic composition may include about 0.05 to about 20% by weight of the one or more solvents capable of solubilizing the hydrophobic polymer, based on the total weight of the cosmetic composition. In other embodiments, the total amount of the one or more solvents capable of solubilizing the hydrophobic polymer may be from about 0.05 to about 15 wt%, from about 0.05 to about 10 wt%, from about 0.05 to about 8 wt%, from about 0.05 to about 5 wt%, from about 0.05 to about 3 wt%, from about 0.1 to about 20 wt%, from about 0.1 to about 15 wt%, from about 0.1 to about 10 wt%, from about 0.1 to about 8 wt%, from about 0.1 to about 5 wt%, from about 0.1 to about 3% by weight, about 0.5 to about 20% by weight, about 0.5 to about 15% by weight, about 0.5 to about 10% by weight, about 0.5 to about 8% by weight, about 0.5 to about 5% by weight, or about 0.5 to about 3% by weight, about 2 to about 20% by weight, about 2 to about 15% by weight, about 2 to about 10% by weight, about 5 to about 20% by weight, about 5 to about 10% by weight, about 10 to about 30% by weight or about 15 to about 30% by weight based on the total weight of the cosmetic composition. a.

Surfactant#
[0067] As used herein, 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 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.
[0068] 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."
[0069] A “detergent” is a surfactant that has cleaning properties in dilute solutions and is generally anionic.
[0070] The surfactants may be anionic, cationic, amphoteric (zwitterionic) or non-ionic. Preferably, the emulsions of the present case include one or more surfactants chosen from anionic surfactants, amphoteric surfactants (zwitterionic), 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 nonionic surfactants, or mixtures thereof.
[0071] 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.
[0072] In a preferred embodiment, the cosmetic composition includes one or more biosurfactants. In other embodiments, the cosmetic composition includes one or more biosurfactants and one or more additional surfactants other than the one or more biosurfactants selected from anionic surfactants, nonionic surfactants, amphoteric surfactants, or combinations thereof. Biosurfactant
[0073] 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.
[0074] 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.
[0075] 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.
[0076] 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.
[0077] 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.
[0078] 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.
[0079] 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.
[0080] 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.
[0081] 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.
[0082] The term “rhamnolipids” includes compounds of general formula (II) and their salts, OH OH H
[0083] 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. • 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-{I-3-[2-O-(αL-rhamnopyranosyl)-αL-rhamnopyranos yl]oxydecanoyl}oxydecanoate).
[0084] The term "di-rhamnolipid" in the context of the present invention denotes compounds of the general formula (II) or their salts, where nRL=1.
[0085] The term "monorhamnolipid" in the context of the present invention denotes compounds of general formula (II) or their salts, where nRL=0.
[0086] The distinct rhamnolipids are abbreviated according to the following nomenclature: "diRL-CXCY" denotes the 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)O—CH3 where o=Y-4.

[0157] Droplet size can be determined using Brookhaven Dynamic Light Scattering (DLS). DLS is a technique used to determine the size of droplets in a colloidal system or emulsion. When samples are illuminated with a monochromatic laser beam, the particles in the samples undergo Brownian motion, causing 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.

EXAMPLES
[0200] An implementation of the present disclosure is provided by means of the following examples. The examples serve to illustrate the technology without being limiting in nature. Example 1
[0201] Composition A is a composition of the invention containing MycelX®. Composition B is identical to Composition A, but does not include MycelX®. Composition A of the invention was prepared by first combining MycelX® (Composition A), caprylic / capric triglyceride, surfactants (mRhamnolipid and sodium methyl cocoyl taurate), and ceramide, with only a small amount of water (about 15 to about 30% by weight, based on the total weight of the final cosmetic composition). A homogeneous composition was obtained, which was further diluted with water and gently mixed or stirred to form the final oil-in-water emulsion. Comparative Composition B was prepared based on a standard preparation procedure for oil-in-water emulsions. The ingredients were combined, without generating a first composition with a limited amount of water.The composition was processed using a high-speed Silverson homogenizer capable of generating fine droplet sizes in the range of 2 to 5 microns. Although the compositions were subjected to the high-speed homogenization process, the droplet size of the resulting emulsions was greater than 1 micron.

[0205] After the emulsions were formed, 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 the particles in 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 particles, from which the size distribution is inferred using mathematical models. Brookhaven's DLS instruments use advanced algorithms to accurately interpret the data, providing insights into the dynamic behavior and size characteristics of particles ranging from a few nanometers to several micrometers in a liquid medium.
[0206] Cryo-scanning electron microscopy (Cryo-SEM) was used to visualize the droplets / spherical structures formed in Composition A of the invention. Cryo-SEM is a technique used to examine the ultrastructure of biological and other samples at cryogenic temperatures. It involves rapidly freezing the sample to preserve its native structure, transferring it to the SEM chamber while maintaining cryogenic conditions, and then imaging the sample surface using electrons. This method provides high-resolution images of samples, minimizing damage by beam and charging effects, making it suitable for various applications including structural analysis, cellular imaging and the study of soft materials. An image of a spherical droplet / structures formed in Composition A of the invention is shown in the figure.
[0207] Atomic force microscopy (AFM) is a high-resolution imaging and surface characterization technique used in nanoscience, materials science, and biology. AFM works by scanning a sharp tip (typically a few nanometers in diameter) attached to a flexible cantilever very close to the sample surface. The interaction forces between the tip and the sample surface cause the cantilever to deflect, and this deflection is measured to create high-resolution images and gather information about surface properties. AFM can provide nanoscale topographical information, measure mechanical properties, and even manipulate individual atoms and molecules on a surface. The spherical droplets / structures formed in Composition A of the invention were evaluated by AFM.They were smaller (<1 micron) and more uniformly dispersed (monodispersed) than the droplets of comparative composition B, and they exhibited a soft shell and a hard core with a Young's modulus of ~60 at 300 Mpa by AFM.
[0208] The foregoing description illustrates and describes the disclosure. Furthermore, the disclosure only shows and describes the preferred embodiments, but as aforesaid, it is to be understood that it may be used in various other combinations, modifications, and environments and may be subject to 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.
[0209] As used herein, the terms "comprising," "having," and "including" are used in their broad and non-limiting sense.
[0210] The terms "a", "an", "the" and "the" are understood to encompass the plural and the singular. Thus, the expression "a mixture thereof" also concerns "their mixtures". 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 phrase "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 phrase "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."
[0211] 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.
[0212] 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.
[0213] The expression “one or more” means “at least one” and therefore includes individual components as well as mixtures / combinations.
[0214] The term “plurality” means “more than one” or “two or more”.
[0215] 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 the present disclosure. In various embodiments, the cosmetic compositions of the present disclosure are transparent. This is due, at least in part, to the small size of the dispersed oil droplets.
[0216] The term "translucent" with respect to a translucent composition indicates that the composition has a transmittance of at least 50% at a wavelength of 600 nm, as measured, for example, using a Lambda 40 UV-visible spectrometer. In various embodiments, the cosmetic compositions of the present disclosure are translucent. This is due, at least in part, to the small size of the dispersed oil droplets.
[0217] Except in the working examples, or if otherwise indicated, all quantities 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".
[0218] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise indicated.
[0219] 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).
[0220] 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.
[0221] 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.
[0222] Any components presented positively in the present disclosure may be negatively excluded from the claims, for example, a claimed composition may be “free,” “substantially free” (or “ substantially free”) of one or more components that are positively presented in the present disclosure.
