Description

Title of the invention: HIGH STRENGTH LIFTING AND ANTI-AGING FACIAL MASK WITH SKIN ACTIVE INGREDIENTS FIELD OF THE INVENTION

[0001] The invention relates to a two-part composition for application to the skin to form a high-strength, lifting, anti-aging gel mask to be rinsed off.

[0002] CONTEXT OF THE INVENTION.

[0003] The skin produces less collagen and elastin as it ages. For example, after the age of twenty, a person (human) produces about one percent less collagen in their skin each year. As a result, the skin becomes thinner and more fragile. Inevitably, dark spots, redness, wrinkles, crow's feet, age spots, bags under the eyes and the like may begin to form.

[0004] Consumers often wish to improve the appearance of these age-related skin imperfections, and seek instant and long-lasting results. Many consumer products and procedures are dedicated to concealing and reducing skin flaws and imperfections. Some employ medical procedures while others include makeup, foundations, and masks, as well as topical products to provide hydration, such as lotions and creams. Some of these products contain active ingredients, for example, nia-cinamide, which help repair and rejuvenate the skin over time, as well as peptides and plant extracts. Unfortunately, these products and procedures have drawbacks. For example, after makeup-type solutions are removed, the skin looks the same as it did before the makeup was applied.Additionally, makeup products are often visible, offer minimal textural benefits, and lack lasting effects on the skin, making them less appealing as an anti-aging solution. Similarly, moisturizers don't address fine lines and wrinkles, at least in the short term. And, of course, many consumers can't afford or prefer to undergo such drastic cosmetic clinical procedures.

[0005] Attempts have been made to develop new product categories to improve the appearance of the skin without the disadvantages of existing products and procedures. One such product family can generally be classified as "adhesive contractile film formers." Film formers are chemical compositions that, when applied to the skin, leave a flexible, cohesive, and continuous coating. A closed group of film formers is also adherent to the skin and contractile. Unfortunately, these film-forming products, while providing dramatic and instant results, quickly lose their skin-tightening effect and elasticity and can turn white, crack, and flake. Additionally, such products can contain harsh ingredients such as peptides and plant extracts that can be irritating, especially when combined with tightening and firming agents, and can be difficult to apply to the skin.

[0006] The present disclosure provides an improved skin firming product that is easy to apply, can be removed with water, does not cause skin irritation, and once removed, provides immediate short-term firming and longer-term benefits to the skin. BRIEF SUMMARY OF THE INVENTION

[0026] Other features and advantages of the present invention will emerge from the following more detailed description, by way of example, of the principles of the invention.

[0027] This disclosure describes particular embodiments in accordance with the general inventive concepts and is not intended to limit the scope of the invention in any way. Indeed, the invention as described herein is broader than, and not limited by, the exemplary embodiments presented herein, and the terms used herein have their full ordinary meanings. DETAILED DESCRIPTION OF THE INVENTION

[0028] In accordance with various embodiments, a two-part cosmetic composition is provided for application to the skin to form a rinse-off gel mask. The cosmetic composition is sensitive skin friendly and provides hydration benefits and soft blurring / blurring effects, providing professional-level transformative results, including skin smoothing, firming, texture improvement, and radiance enhancement, which results are immediate and long-lasting beyond removal of the cosmetic composition from the skin.

[0029] As provided in the article of manufacture, the cosmetic composition provides a professional-type facial treatment that is easy to use and apply and, after gentle rinsing, provides long-lasting benefits that closely match a competitive benchmark product with a different composition platform, and that stands out from the competitive benchmark product when comparing texture, radiance, and skin refinement.

[0030] In some embodiments, the disclosure of the cosmetic composition includes: combinable portions including a first lifting serum portion that includes at least one silicate and water; and a second gelling solution portion that includes at least one crosslinked polyacrylic acid thickener; at least one clay; at least one glycosaminoglycan comprising a hyaluronic acid selected from sodium hyaluronate, hydrolyzed sodium hyaluronate, a hyaluronic acid derivative, or a combination thereof, the at least one glycosaminoglycan having a molecular weight in a range of about 1 million Daltons to about 1.4 million Daltons. The composition allows for the inclusion of skin actives at levels that impart benefits to the skin, including soft blurring of the skin with a smooth texture and long-lasting hydration after rinsing.

[0031] Upon mixing the combinable portions and applying to a substrate, the silicate and polymer film formers of the composition form a semi-solid gel film that can be easily applied after mixing and retained on the skin without dripping until gently removed with water. Without being bound by theory, mixing the lifting serum portion with the gelling solution triggers thickening of the at least one crosslinked polyacrylic acid thickener (exemplified herein by a carbomer) which initiates the sol-gel transition of the sodium silicate. In a pH range of about 9 to 11, and in particular embodiments at a pH of about 10.8, the two portions form a silica gel that imparts a transformative texture that instantly lifts the skin and, upon rinsing, unexpectedly imparts long-lasting effects.In various embodiments, the crosslinked polyacrylic acid thickener and the silicate ingredients are provided in the composition in a beneficial ratio that allows for the formation of a silica gel that can be spread on the skin after mixing and is sufficiently firm to be retained on the skin until rinsing, wherein the ratio of crosslinked polyacrylic acid thickener to silicate is in a range of about 1:1 to 1:8, in some embodiments about 1:2 to about 1:3, or about 1:2.5.

[0032] In some embodiments, the cosmetic composition is free or essentially free of ingredients that would substantially alter the pH, as described herein, including acids and reactive ingredients that would produce acidic by-products, plasticizers such as glycerin (also identified herein as a moisturizing or humectant). In some embodiments, the composition is free or essentially free of niacinamide. In some embodiments, the composition is free or essentially free of peptides. In some embodiments, the composition is free or essentially free of plant extracts, e.g., but not limited to, Camellia Sinensis Leaf Extract, Nelumbo Nucifera (Lotus) Seed Extract, Root Extract of Sophora Angustifolia, Rhus Semialata Extract, Ginkgo Biloba Leaf Extract, Lonicera Japonica (Honeysuckle) Flower Extract, Camellia Sinensis Leaf Extract, Portulaca Oleracea Extract.

[0033] In some embodiments, the inventive composition is used on one or more of or all of the body, face, hair and / or scalp, and distinct body parts. The cosmetic composition may be used on "normal" or other than normal skin, and for example, may be dry or oily. LIFTING SERUM PART Silicate

[0034] According to the disclosure, the cosmetic composition includes at least one silicate.

[0035] In various embodiments, the at least one silicate is selected from the group consisting of sodium silicate, magnesium silicate, calcium silicate, aluminum silicate, and combinations thereof. In some particular embodiments, the silicate is sodium silicate. Examples of silicates that may be obtained commercially include hydrated sodium silicate powders that are water-soluble, including those selected from BRITESIL C 205, BRITESIL C207, from PQ Corporation, and combinations thereof. In some embodiments, the at least one silicate includes BRITESIL C 205.

[0036] In some embodiments, the at least one silicate comprises a sodium silicate. In some embodiments, the sodium silicate is present in a range of about 1% to about 15%, or about 3.3% by weight, based on the weight of the cosmetic composition. In some embodiments, the sodium silicate is represented by the formula Na2O-(SiO2)x, where x is the ratio of silicon dioxide (SiO2) to sodium oxide (Na2O) by weight, wherein the silicon dioxide (SiO2) is present with the sodium oxide (Na2O) at a weight ratio ("x") in a range of about 2.0 to about 3.4, or about less than 2.4.

[0037] In various embodiments, the total amount of silicate present in the cosmetic composition is in an amount of from about 1% to about 20%, or from about 1% to about 15%, or from about 1% to about 9%, or from about 2% to about 4%, or any suitable combination, subcombination, range or subrange of these values by weight, based on the total weight of the cosmetic composition. However, those skilled in the art will appreciate that other ranges are within the scope of the invention.

[0038] Thus, the at least one silicate is present, by weight, based on the total weight of the composition, from about 1.0, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 to about 20 weight percent, including intermediate increments and ranges. Solvent / water

[0039] In accordance with the various embodiments, water is present in the cosmetic compositions in a range of from about 80% to about 98%, or from about 85% to about 95%, or from about 89% to about 95%, or any suitable combination, subcombination, range, or subrange of these values by weight, based on the weight of the cosmetic composition. In some embodiments, water is present in the cosmetic composition in an amount of at least about 94% by weight, based on the weight of the cosmetic composition. However, those skilled in the art will appreciate that other ranges are within the scope of the invention. Thus, water is present, by weight, relative to the total weight of the cosmetic composition, from about 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, to about 98 percent by weight, including increments and ranges therein.

[0040] In some embodiments, water is present in a range of about 89% to about 98%, or about 94% by weight, based on the weight of the cosmetic composition.

[0041] The water used may be sterile demineralized water and / or floral water such as rose water, cornflower water, chamomile water or linden water, and / or natural thermal or mineral water such as, for example: Vittel water, Vichy basin water, Uriage water, La Roche-Posay water, La Bourboule water, Enghien-les-Bains water, Saint-Gervais-les-Bains water, Néris-les-Bains water, Allevar-les-Bains water, Digne water, Maizières water, Neyrac-les-Bains water, Lons-le-Saunier water, Eaux-Bonnes water, Rochefort water, Saint-Christau water, Les Fumades water, Tercis-les-Bains water or Avène water. The aqueous phase can also include reconstituted thermal water, i.e. water containing trace elements such as zinc, copper, magnesium, etc., which restore the characteristics of thermal water.

[0042] In some embodiments, the cosmetic composition may include one or more additional water-soluble solvents. Non-limiting examples of water-soluble solvents include, for example, glycerin, C1-4 alcohols, organic solvents, fatty alcohols, fatty ethers, fatty esters, polyols, glycols, vegetable oils, mineral oils, liposomes, laminar lipid materials, or any mixtures thereof. Examples of organic solvents that may be mentioned, but are not limited to, monoalcohols and polyols such as ethyl alcohol, isopropyl alcohol, propyl alcohol, benzyl alcohol and phenylethyl alcohol, or glycols or glycol ethers such as, for example, monomethyl, monoethyl and monobutyl ethers of ethylene glycol, propylene glycol or their ethers such as, for example, monomethyl ethers of propylene glycol, butylene glycol, hexylene glycol, dipropylene glycol as well as alkyl ethers of diethylene glycol, for example, monoethyl ether or monobutyl ether of diethylene glycol.

[0043] In some embodiments, the cosmetic composition may be free or essentially free of one or more plasticizers, for example, plasticizers selected from the group consisting of phthalate esters, adipates, citrates, alkane dicarboxylic acids, glycols, and phosphates. Thus, in some examples, the composition may be free of glycerin, propylene glycol, polyethylene glycol, glycerol, sorbitol, dipropylene glycol, propane diol, triethyl citrate, isohexadecane, and combinations thereof.

[0044] Optionally, the total amount of one or more water-soluble solvents may be from about 0.1% to about 20%, or from about 0.1% to about 15%, or from about 0.1% to about 10%, or from about 0.1% to about 0.5%, or any suitable combination, subcombination, range or subrange of these values by weight, based on the total weight of the cosmetic composition.

[0045] In some embodiments, the cosmetic composition includes butylene glycol. In some embodiments, butylene glycol is present at about 0.3% by weight relative to the total weight of the composition. pH of the cosmetic composition

[0046] The pH of the cosmetic composition is between 9 and 11, or between 9.5 and 11, or between 10.2 and 11, or between 10.5 and 11 and, in certain embodiments, is about 10.8. The pH may be corrected to the desired value by adding a base (organic or inorganic) to the cosmetic composition, for example ammonia or a primary, secondary or tertiary (poly)amine, such as monoethanolamine, diethanolamine, triethanolamine, isopropanolamine or 1,3-propanediamine, or alternatively by adding an inorganic or organic acid, advantageously a carboxylic acid, such as, for example, citric acid.

[0047] As disclosed herein, the pH may also be selected by varying the proportions of the gelling portion comprising the at least one crosslinked polyacrylic acid thickener (in some embodiments a carbomer), the lifting serum portion comprising the silicate (in some embodiments sodium silicate).

[0048] Accordingly, the pH may be in a range of about 9 to about 11, including intermediate 0.01 increments, and in some examples, the pH may be in a range of about 10.50, 10.51, 10.52, 10.53, 10.54, 10.55, etc. to about 10.81, 10.82, 10.83, 10.84, 10.85, etc. to about 11.00.

[0049] Maintaining the pH within the described range is influenced by the relative proportions of thickener comprising polymer and silicate. Given the relatively high pH of the silicate compared to that of the thickener, an imbalance of these ingredients may cause the composition to become cloudy and sticky or unusable. Accordingly, the ratio of crosslinked polyacrylic acid thickener (e.g., carbomer) to silicate (e.g., sodium silicate) is in the range of about 1:1 to 1:8, inclusive of increments and intermediate ranges. In some embodiments, the ratio is in the range of about 1:1 to 1:4, or about 1:1.5 to about 1:3.5, or about 1:3, and in some examples about 1:2.6. Alternatively, the ratio may be 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7 to 1:8, inclusive of increments and intermediate ranges, based on the total weight of the cosmetic composition GELLING SOLUTION PART Thickener (carbomer)

[0050] According to the disclosure, the cosmetic composition includes at least one thickener.

[0051] In some particular embodiments, the thickener is a crosslinked polyacrylic acid, for example, a carbomer. Examples of crosslinked polyacrylic acid thickeners may be obtained commercially from Lubrizol (TM) as one of Carbopol Ultrez (TM)- Carbopol Ultrez 10, 21, 30, as polymerized crosslinked polyacrylic acid and provided in a cosolvent system and providing good electrolyte tolerance and thickening performance over a wide pH range, for example wherein the pH is between 9 and 11, and in some embodiments, about 10.8.

[0052] In some embodiments, the at least one thickener comprises a carbomer. In some embodiments, the carbomer is present in a range of about 1% to about 2%, or about 1.3% by weight, based on the weight of the cosmetic composition.

[0053] In various embodiments, the total amount of thickener present in the cosmetic composition is in an amount of from about 0.5% to about 3%, or from about 1% to about 2%, or any suitable combination, subcombination, range or subrange of these values by weight, based on the weight of the cosmetic composition. In some embodiments, the total amount of thickener comprising a crosslinked polyacrylic acid is up to and not more than about 2% by weight, based on the weight of the cosmetic composition. However, those skilled in the art will appreciate that other ranges are within the scope of the invention.

[0054] Thus, one or more thickeners are present by weight, relative to the total weight of the cosmetic composition, of about 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, to about 2.0% by weight, including intermediate increments and ranges. Glycosaminoglycan (hyaluronic acid)

[0055] According to the disclosure, the cosmetic composition includes at least one glycosaminoglycan comprising a hyaluronic acid selected from sodium hyaluronate, hydrolyzed sodium hyaluronate, a hyaluronic acid derivative, or a combination thereof.

[0056] In some embodiments, the at least one glycosaminoglycan comprising a hyaluronic acid selected from sodium hyaluronate, hydrolyzed sodium hyaluronate, a hyaluronic acid derivative, or a combination thereof comprises sodium hyaluronate. In some embodiments, the sodium hyaluronate is present in a range of about 0.01% to about 0.1%, or about 0.07% by weight, based on the weight of the cosmetic composition.

[0057] In some embodiments, the at least one glycosaminoglycan selected from sodium hyaluronate, hydrolyzed sodium hyaluronate, a hyaluronic acid derivative, or a combination thereof has a molecular weight in a range of about 1 million Daltons to about 1.4 million Daltons. In some particular embodiments, the at least one glycosaminoglycan comprising a hyaluronic acid is sodium hyaluronate having a molecular weight of about 1 million Daltons to about 1.4 million Daltons.

[0058] Examples of sodium hyaluronate that may be obtained commercially include Cristalhyal LO (TM) from Givaudan Active Beauty.

[0059] The at least one glycosaminoglycan comprising a hyaluronic acid selected from sodium hyaluronate, hydrolyzed sodium hyaluronate, a hyaluronic acid derivative, or a combination thereof in the cosmetic composition is present in an amount of from about 0.01% to about 0.3%, or from about 0.03% to about 0.25%, or from about 0.05% to about 0.2%, or from about 0.06% to about 0.1%, or from about 0.065% to about 0.08%, or at least 0.02% by weight, or at least 0.05% by weight, or at least 0.075% by weight, or at least 0.1% by weight, or at least 0.2% by weight, or any suitable combination, subcombination, range or subrange of these values by weight, based on the weight total of the cosmetic composition. However, those skilled in the art will appreciate that other ranges fall within the scope of the invention.

[0060] Thus, the at least one glycosaminoglycan comprising a hyaluronic acid selected from sodium hyaluronate, hydrolyzed sodium hyaluronate, a hyaluronic acid derivative, or a combination thereof, is present in an amount by weight, relative to the total weight of the cosmetic composition, of about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, 0.20, to about 0.30 percent by weight, including intermediate increments and ranges. Clay

[0061] According to the disclosure, the cosmetic composition includes at least one clay. A single type of clay can be used, or two or more different types of clay can be used in combination.

[0062] In some embodiments, the at least one clay may be an organophilic clay, more particularly a modified clay, such as hectorite, montmorillonite, bentonite, attapulgite and sepiolite, and mixtures thereof. These clays are modified with a chemical compound selected from quaternary amines, tertiary amines, amine acetates, imidazolines, amine soaps, fatty sulfates, alkylarylsulfonates and amine oxides, and mixtures thereof.

[0063] In some embodiments, the at least one clay is selected from the group consisting of talc, mica, and hectorite.

[0064] In some embodiments, the at least one clay comprises hectorite. In some embodiments, the at least one clay consists of hectorite present in a range of about 0.02% to about 0.1%, or about 0.5% by weight, based on the weight of the cosmetic composition.

[0065] Examples of hectorite that may be obtained commercially include BENTONE HYDROCLAY 2000 LO from Elementis. Other examples include BENTONE HYDROCLAY 2000, BENTONE HYDROCLAY 1100, BENTONE HYDROCLAY 2001, BENTONE HYDROCLAY 2100, BENTONE HYDROCLAY 900, or a combination thereof. In a particular embodiment, BENTONE HYDROCLAY 2000 may be selected.

[0066] In various embodiments, the total amount of at least one clay present in the cosmetic composition is in an amount of about 0.01% to about 0.2%, or about 0.02% to about 0.1%, or about 0.03% to about 0.08%, or about 0.04% to about 0.05%, or at least about 0.02% by weight, or at least about 0.05% by weight, or any suitable combination, subcombination, range or subrange of these values by weight, based on the weight of the cosmetic composition. However, those skilled in the art will appreciate that other ranges are within the scope of the invention.

[0067] Thus, each of the at least one clay is present in an amount by weight, relative to the total weight of the cosmetic composition, of about 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.10, to about 0.2 percent by weight, including intermediate increments and ranges.

[0068] The term "clay" refers to a naturally occurring material composed primarily of fine-grained minerals, which is generally plastic at an appropriate water content and hardens when dried or fired. Although clay usually contains phyllosilicates, it may contain other materials that impart plasticity and harden when dried or fired. Associated phases in clay may include materials that do not impart plasticity and organic matter. A A common definition is that of the Penguin Dictionary of Science, namely “finely divided rocky materials whose component minerals are various silicates, chiefly of magnesium or aluminum.” Clay includes kaolinite (typically defined as [Si4]Al4Oi0(OH)8.nH2O (n=0 or 4)), illite (typically defined as Mx[Si6.8Ali.2]Al3Fe.025Mg.75O20(OH)4), vermiculite (typically defined as Mx[Si7AlJAlFe.05Mgo.5O20(OH)4), smectite (typically defined as MX[Si8]Al3.2Feo.2Mgo.eO20(OH)4, chlorite (typically defined as (Al(0H)2.55)4[Si6.8A10i.2}Al3.4Mg0.6)2o(OH)4), and phyllosilicate minerals or talc (typically defined as Mg3Si4Oi0(OH)2).

[0069] Another definition, frequently used by chemists, is "a sediment or sedimentary rock of natural origin composed of one or more minerals and accessory compounds, the whole usually being rich in hydrated aluminum silicate, iron or magnesium, hydrated alumina, or iron oxide, mainly in particles of colloidal or quasi-colloidal size, and commonly developing plasticity when sufficiently pulverized and wetted" (see Kirk-Othmer, Encyclopaedia of Chemical Technology, Volume 5, page 544, 2nd edition, John Wiley and Sons, Inc., New York, 1964). Examples of clays are given in the book "Clay mineralogy, S. Caillere, S. Hénin, M. Rautureau, 2nd edition 1982, Masson". Clays can be of natural or synthetic origin.

[0070] Hydrophilic clay includes smectites such as saponites, hectorites, montmorillonites, bentonites and beidellite. Hydrophilic clay includes synthetic hectorites (also called laponites) such as the products sold by the company under the name Laporte Laponite XLG, Laponite RD, Laponite RDS (these products are sodium silicates and magnesium silicates, particularly sodium, lithium and magnesium), bentonites such as the product sold under the name Bentone® HC Rheox, magnesium silicates and aluminum-based products such as the hydrated products sold by the Vanderbilt company under the name Ultra Veegum®, Veegum® HS, Veegum® DGT, or calcium silicates, particularly the synthetic form sold by the company under the name Micro-Cel® C.Fuller's earth consists primarily of hydrated aluminum silicates that contain metal ions such as magnesium, sodium, and calcium in their structure. Montmorillonite is the primary clay mineral in Fuller's earth, but it may contain other minerals such as kaolinite, attapulgite, and palygorskite, among other components.

[0071] A lipophilic clay refers to a swellable clay in a lipophilic medium, the clay swells and forms a colloidal dispersion. Lipophilic clays include modified clays such as modified magnesium silicate hectorites (Bentone gel VS38 from Rheox) modified with a C10 to C22 ammonium chloride fatty acid, such as hectorite modified with distearyldimethylammonium chloride (CTFA name: Disteardimonium hectorite) sold under the name “Bentone 38 CE” by Rheox or Bentone® 38V by ELEMENTIS.

[0072] The origin of such clay may be a natural or synthetic mineral clay, such as hectorite, bentonite and their quaternized derivatives, which are for example obtained by reacting the minerals with a quaternary ammonium compound, such as stearalkonium bentonite, hectorites, quaternized hectorites such as Quatemium-18 hectorite, carbonates such as propylene carbonate, bentones, and the like.

[0116] EXAMPLE 5: Effect of pH on the composition after mixing the parts

[0117] A study of the inventive composition was conducted in which the ratio between the silicate and the thickener was variable to effectively vary the pH of the composition. The inventors demonstrated that in embodiments with varying proportions of the two parts and a pH in the range of 9 to 11, above a pH of 11, the gel mask has a fine liquid texture that drips when applied to a substrate and below a pH of 10.5, the gel forms visible gel lumps in the composition. The exemplary inventive composition as disclosed herein, having a ratio of crosslinked polyacrylic acid thickener to silicate of about 1:2.5 and a pH of about 10.8 produced a gel mask that was smooth and easily spreadable. Accordingly, with the disclosed and claimed ratio of polyacrylic acid thickener to silicate in a range of about 1:1 to 1:8 and a pH in the range of 9 to 11, a gel mask-forming composition having variable textural properties is provided.

[0118] EXAMPLE 6: In vivo skin tests after rinsing

[0119] In vivo tests on subjects were conducted to evaluate hectorite retention on the skin to impart blurring effects, and to evaluate the hydration effects after application to the skin and subsequent rinsing of the inventive composition 1 according to the present disclosure.

[0120] Evaluation of the stratum corneum using confocal Raman (zscan) demonstrated post-rinse retention of the silica film within the stratum corneum, believed to encapsulate the hectorite, with the inventive composition 1.

[0121] Hydration was also assessed using confocal Raman (zscan); comparison between Inventive 1 and the standard product demonstrated that hydration performance is improved with the inventive composition compared to the standard product.

[0122] The articles "a" and "an" as used herein, mean one or more when applied to any feature in embodiments of the present invention described in the specification and claims. The use of "a" and "an" does not limit the meaning to a single feature, unless such a limitation is specifically stated. The article "the", "the", "the" preceding singular or plural nouns or noun phrases denotes a specified particular feature or specified particular features and may have a singular or plural connotation depending on the context in which it is used. The adjective "any", "all" means one, some or all indiscriminately, regardless of quantity.

[0123] “One or more,” as used herein, means at least one, and thus includes individual components as well as mixtures / combinations.

[0124] The transitional terms "comprising", "consisting essentially of" and "consisting of", when used in the appended claims, in their original and amended form, define the scope of the claims with respect to additional unmentioned elements or steps, if any, which are excluded from the scope of the claim(s). The term "comprising" is intended to be inclusive or broad and does not exclude any additional, unenumerated element, process, step or material. The term "consisting of" excludes any element, step or material other than those specified in the claims and, in the latter case, impurities ordinarily associated with the specified material(s). The expression "consisting essentially of" tially in" limits the scope of a claim to the specified elements, steps or material(s) and to those which do not materially affect the fundamental and novel feature(s) of the claimed invention. All methods and materials described herein which incorporate the present invention may, in alternative embodiments, be more specifically defined by any of the transitional terms "comprising", "consisting essentially of" and "consisting of".

[0125] In addition to 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 within 10% of the number indicated (e.g., "about 10%" means 9% to 11% and "about 2%" means 1.8% to 2.2%).

[0126] All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total composition unless otherwise indicated.

Accordingly, the weight percentage of an active ingredient in a composition is represented as the amount of raw material containing the active ingredient that is used and may or may not reflect the final percentage of the active, where the final percentage of the active depends on the weight percentage of the active ingredient in the raw material.

[0127] All ranges and amounts set forth herein are intended to include subranges and amounts using any disclosed point as a boundary. Thus, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%" is intended to encompass ranges of "1% to 8%," "1% to 5%," "2% to 10%," and so on. All numbers, amounts, ranges, and so on are intended to be modified by the term "about," whether or not expressly stated. Similarly, a given range of "about 1% to 10%" is intended to have both its 1% and 10% boundaries modified by the term "about." Furthermore, it is understood that when an amount of a component is given, it is intended to mean the amount of the active ingredient unless specifically stated otherwise.

[0128] Although the numerical ranges and parameters within the general scope of the disclosure are approximations, unless otherwise indicated, the numerical values presented in the specific examples are reported as accurately as possible. However, any numerical value inherently contains certain errors necessarily resulting from the standard deviation found in their respective test measurements. The following example serves to illustrate embodiments of the present di- dissemination without however being of a limiting nature.
