COMPOSITIONS AND METHODS FOR IMPROVING THE APPEARANCE OF THE

SKIN

TECHNICAL FIELD

[0001] The disclosure relates to compositions and methods for improving the appearance of the skin.

BACKGROUND

[0002] When considering cosmetics, many consumers wish to improve the appearance of, or hide, skin imperfections such as acne, scars, enlarged pores, dark spots, uneven pigmentation, and so on. Typically, consumers also desire for a cosmetic formulation to be lasting on the skin, so that it won't be inadvertently removed before the consumer wishes to remove it, revealing the skin imperfection.

[0003] While traditional cosmetic formulations such as foundation or concealer types of make-up may improve the appearance of some skin imperfections, such formulations may not be able to satisfactorily reduce the appearance of more pronounced skin imperfections, such as scars. Further, such formulations may not have the remanence needed to last as long as the user would like the imperfections to remain covered, for example the foundation or concealer may come off when the user sweats.

[0004] As an alternate to such topical cosmetic formulations, more invasive techniques such as surgery, fillers, or laser resurfacing of the skin may provide longer-lasting effects and can treat prominent imperfections. However, many consumers either cannot afford, or do not wish, to undergo such drastic cosmetic treatments. [0005] As such, there is a consumer desire for topical cosmetic formulations that are effective at reducing the appearance of skin imperfections, while being long- lasting.

SUMMARY

[0006] The disclosure relates to long-lasting compositions and methods for improving the appearance of the skin.

[0014] As used herein, the term "forms quickly" means that the film forms within less than about 30 minutes, such as less than about 20 minutes, less than about 15 minutes, or less than about 10 minutes, after the composition is applied to the skin. [0015] As used herein, the term "blur" with regard to skin imperfections means that the visual appearance of the imperfection is less noticeable.

[0016] As used herein, the term "reducing" of the appearance of skin imperfections means that the skin imperfection is hidden or blurred, such that the imperfection is less noticeable.

[0017] As used herein, the term "soft focus" means that the visual appearance of the skin is more homogenous and matte, leading to the blurring or hiding of skin imperfections.

[0018] As used herein, "durable" means the film will not easily rub off, or will not be removed by sweat, water, makeup, lotions, or the like, such that the film will remain substantially intact until removed by the user.

Compositions

[0019] According to various embodiments, the compositions comprise at least one thermoplastic elastomer, at least one adhesive polymer, and at least one filler, which together form an association, and may further comprise at least one colorant. Additional optional components, such as solvents, silicone elastomers, humectants, and water, may also be included in the compositions.

Thermoplastic Elastomer

[0020] According to various exemplary and non-limiting embodiments, the at least one thermoplastic elastomer may be chosen from block copolymers having at least two glass transition temperatures ("T _g "). The block copolymers may be hydrocarbon-soluble or dispersible in the oily phase. In various embodiments, the at least one thermoplastic elastomer may be amorphous, crystalline, or semicrystalline.

[0021] The block copolymers comprise one or more hard segments attached to one or more soft segments. The hard segments of the thermoplastic elastomer may comprise vinyl monomers in varying amounts. Examples of suitable vinyl monomers include, but are not limited to, styrene, methacrylate, acrylate, vinyl ester, vinyl ether, vinyl acetate, and the like. The soft segments may comprise olefin polymers and/or copolymers which may be saturated, unsaturated, or combinations thereof. Exemplary olefin copolymers may include, but are not limited to,

ethylene/propylene copolymers, ethylene/butylene copolymers, propylene/butylene copolymers, polybutylene, polyisoprene, polymers of hydrogenated butanes and isoprenes, and mixtures thereof.

[0022] By way of example, the at least one thermoplastic elastomer may be chosen from diblock, triblock, multiblock, radial, and star copolymers obtained by polymerizing at least one unsaturated hydrocarbon monomer having 2 to 5 carbon atoms and having one or two ethylenic unsaturations. Non-limiting examples of unsaturated hydrocarbon monomers having 2 to 5 unsaturated carbon atoms include ethylene, propylene, butadiene, isoprene or pentadiene. In various exemplary and non-limiting embodiments, block copolymers may be chosen from those comprising at least one styrene block and at least one block comprising units selected from butadiene, ethylene, propylene, butylene, isoprene, or mixtures thereof.

[0023] Optionally, the block copolymer may be hydrogenated to reduce the residual ethylenic unsaturation after the polymerization of the monomers. For example, the hydrocarbon-based block copolymer may optionally be a hydrogenated copolymer comprising styrene blocks and ethylene blocks/C3-C ₄ alkylene or isoprene blocks. In one exemplary embodiment, the block copolymer is an amorphous hydrocarbon block copolymer, for example an amorphous hydrocarbon block copolymer of styrene and monomers of hydrocarbon containing 2 to 5 carbon atoms and comprising one or two ethylenic unsaturations.

[0024] The amorphous thermoplastic elastomers comprise at least one first block whose T _g is below about 20°C, such as below about 0°C, below about -20°C, or below about -40°C. The T _g of the first block can, for example, range from about - 150°C to about 20°C, such as from about -100°C to about 0°C. The block

copolymers also comprise at least one second block whose T _g is greater than about 25°C, such as greater than about 50°C, greater than about 75°C, greater than about 100°C, or greater than about 150°C.

[0025] Exemplary, non-limiting amorphous diblock copolymers may be chosen from styrene-ethylene/propylene copolymers, styrene-ethylene/butadiene

copolymers, styrene-ethylene/butylene copolymers, styrene-butadiene, or styrene- isoprene copolymers. Diblock copolymers are sold, for example, under the name Kraton® G1701 E by Kraton Polymers.

[0026] Exemplary, non-limiting amorphous triblock copolymers may be chosen from styrene-ethylene/propylene-styrene copolymers, styrene-ethylene/butadiene- styrene copolymers, copolymers of styrene-isoprene-styrene, and copolymers of styrene-butadiene-styrene, such as those sold under the names Kraton® G1650, Kraton® D1 101 , D1 102 Kraton®, Kraton® D1 160 by Kraton Polymers. In one exemplary embodiment, the thermoplastic elastomer may be a mixture of a triblock copolymer styrene-butylene/ethylene-styrene diblock copolymer and a styrene- ethylene/butylene, such as those sold under the name Kraton® G1657M by Kraton Polymers. In a further example, the thermoplastic elastomer may be a mixture of hydrogenated triblock copolymer styrene-butylene/ethylene-styrene hydrogenated star polymer and ethylene-propylene-styrene, such mixing can in particular be in isododecane in another oil. Such mixtures are sold, for example, by Penreco under the trade names VERSAGEL® M5960 and M5670 VERSAGEL®.

[0027] In further exemplary embodiments, the at least one thermoplastic elastomer is chosen from semicrystalline block copolymers having at least two glass transition temperatures. The semicrystalline block copolymers can comprise at least one first block whose T _g is greater than about 40°C, such as greater than about

75°C, or greater than 100°C. The T _g of the first block can, for example, range from about 40°C to about 150°C, such as from about 50°C to about 100°C. The semcrystalline block copolymers also comprise at least one second block whose T _g is less than about -50°C, such as less than about -75°C, less than about -100°C, or less than about -150°C. The T _g of the second block can, for example, range from about -150°C to about -50°C, such as from about -100°C to about -50°C.

[0028] By way of non-limiting example, the semicrystalline thermoplastic elastomers may be chosen from copolymers containing a polyamide and/or a polysilicone and/or a polyurethane, for example polysilicone-polyamides or polysilicone-polyurethanes. For example, the semicrystalline thermoplastic elastomers may be chosen from polyorganosiloxane-containing polymers comprising at least one moiety corresponding to formula I:

For example, the at least one adhesive polymer may be present in an amount ranging from about 0.5% to about 10%, about 1 % to about 8%, about 1 .5% to about 6%, or about 2% to about 4% by weight, relative to the weight of the composition. In one embodiment, the at least one adhesive polymer is present in an amount ranging from about 1 % to about 3%.

[0037] As non-limiting examples of adhesive polymers having a T _g greater than about 25°C, mention may be made of polymer particles of C C ₄

alkyl(methacrylate)polymer, stabilized in a non-aqueous dispersion, referred to herein for ease of reference as an "oil dispersion," such as those described in WO2015/091513 which is incorporated by reference herein.

[0038] By way of example, the CrC ₄ alkyl (meth)acrylate monomers may be chosen from methyl (meth)acrylate, ethyl (meth)acrylate, n-propyl (meth)acrylate, isopropyl (meth)acrylate, n-butyl (meth)acrylate and tert-butyl (meth)acrylate. For example, the polymer may be a methyl acrylate and/or ethyl acrylate polymer.

According to one exemplary embodiment, the polymer consists essentially of a polymer of one or more Ci-C ₄ alkyl (meth)acrylate monomers. According to another exemplary embodiment, the polymer consists essentially of a copolymer of C C ₄ (meth)acrylate and of (meth)acrylic acid or maleic anhydride.

[0042] By way of non-limiting example only, the polymer of the particles in the oil dispersion, which may optionally be crosslinked or alternatively may not be crosslinked, may be chosen from methyl acrylate homopolymers, ethyl acrylate homopolymers, methyl acrylate/ethyl acrylate copolymers, methyl acrylate/ethyl acrylate/acrylic acid copolymers, methyl acrylate/ethyl acrylate/ maleic anhydride copolymers, methyl acrylate/acrylic acid copolymers, ethyl acrylate/ acrylic acid copolymers, methyl acrylate/maleic anhydride copolymers, and ethyl acrylate/maleic anhydride copolymers.

[0043] The polymer of the particles in the dispersion may have a number- average molecular weight ranging from about 2000 to about 10,000,000, for example ranging from about 150,000 to about 500,000. The polymer particles may be present in the oil dispersion in a content ranging from about 20% to about 60%, for example about 21 % to about 58.5%, about 30% to about 50%, about 35% to about 45%, or about 36% to about 42%, by weight, relative to the total weight of the oil dispersion.

For example, the weight ratio may range from about 4.5 to about 19, such as from about 5 to about 19, or from about 5 to about 12.

[0045] By way of example only, the stabilizer may be chosen from isobornyl acrylate homopolymers, statistical copolymers of isobornyl acrylate/methyl acrylate, statistical copolymers of isobornyl acrylate/methyl acrylate/ethyl acrylate, and statistical copolymers of isobornyl methacrylate/methyl acrylate.

[0046] In various embodiments, the stabilizer may have a number-average molecular weight ranging from about 10,000 to about 400,000, such as from about 20,000 to about 200,000. [0047] In various embodiments, the combination of the stabilizer + polymer of the particles present in the oil dispersion comprises from about 10% to about 50%, such as about 15% to about 30%, by weight of polymerized isobornyl (meth)acrylate, and from about 50% to about 90%, such as about 70% to about 85%, by weight of polymerized CrC ₄ alkyl (meth)acrylate, relative to the total weight of the combination of the stabilizer + polymer of the particles.

[0048] The oily medium of the oil dispersion comprises a hydrocarbon-based oil. The hydrocarbon-based oil is an oil that is liquid at room temperature (25°C). The term "hydrocarbon-based oil" means an oil formed essentially from, or even consisting of, carbon and hydrogen atoms, and optionally oxygen and nitrogen atoms, and not containing any silicon or fluorine atoms. It may contain alcohol, ester, ether, carboxylic acid, amine and/or amide groups.

[0049] Exemplary and non-limiting embodiments of the hydrocarbon-based oil medium of the oil dispersion include hydrocarbon-based oils containing up to about 40, such as from 8 to 16 or from 8 to 14, carbon atoms. Optionally, the hydrocarbon- based oil is apolar. For example, the hydrocarbon based oil may be chosen from isododecane.

[0050] The oil dispersion may be prepared, for example, as described in WO2015/091513.

[0051] Alternatively, the adhesive polymer may be chosen from aliphatic or cycloaliphatic hydrocarbon polymers selected from aliphatic or cycloaliphatic hydrocarbon resins having a T _g greater than about 25°C. By "aliphatic or

[0078] It should be understood that the greater amount of colorant added, the greater the effects of the film on the skin to hide skin imperfections, such as pores, pimples, dark spots, and the like. Therefore, the skilled artisan will be able to choose an amount of colorant appropriate for the composition, keeping in mind the intended use of the final formulation. Additional Components

[0079] The compositions according to the disclosure may optionally further comprise additional components, such as solvents, silicone elastomers, humectants, and water.

[0080] The compositions may comprise at least one solvent. Optionally, the compositions may comprise at least one solvent having a vapor pressure at room temperature (25°C) of greater than about 100Pa, such as greater than about 500Pa, or greater than about 1000Pa. In various embodiments, the composition is free or substantially free of solvents having a vapor pressure at room temperature (25°C) of less than about 25Pa.

For example, the at least one solvent may be present in the composition in an amount ranging from about 40% to about 95%, such as about 50% to about 90%, or about 60% to about 85%, or about 65% to about 80%. Silicone Elastomer

[0086] The composition may further optionally comprise at least one silicone elastomer. Surprisingly, in certain embodiments, the at least one silicone elastomer may improve properties such as the thickness and water-resistance of the film, without significantly affecting the mechanical or optical properties of the film. In other embodiments, the addition of at least one silicone elastomer may decrease wettability by sebum, which will help prevent the film from losing tightening

properties. It may, in at least certain embodiments, be advantageous to choose a silicone elastomer having greater than 1 % active material (AM), such as greater than 2% AM.

[0087] The at least one silicone elastomer may, for example, be chosen from at least one silicone crosspolymer dispersed in at least one oil. The at least one silicone crosspolymer may, in certain embodiments, be chosen from dimethicone crosspolymers, such as dimethicone/vinyl dimethicone crosspolymers and

dimethicone/phenyl vinyl dimethicone crosspolymers. In other embodiments, the silicone cross-polymer may be modified by one or more groups chosen from alkyl, polyether, polyglycerin groups. For instance, the alkyl modified silicone crosspolymers may be chosen from vinyl dimethicone/lauryl dimethicone cross-polymers, cetearyl dimethicone cross-polymers, and C3o-C ₄ 5 alkyl cetearyl dimethicone crosspolymers. Non-limiting examples of polyether modified silicone cross-polymers include dimethicone/PEG-10/15 cross-polymers. Exempary alkyl and polyether modified silicone cross-polymers may be chosen, for example, from PEG-10/lauryl dimethicone cross-polymers and PEG-15/lauryl dimethicone cross-polymers. Exemplary polyglycerin modified silicone cross-polymers include dimethicone/ polyglycerin-3 cross-polymers and lauryl dimethicone/polyglycerin-3 cross-polymers.

[0088] In at least certain embodiments, the silicone polymers do not comprise polyethylene glycol or polypropylene groups, or hydrophilic moieties.

vinyldimethyl/trimethylsiloxysilicate stearyl dimethicone crosspolymer (20% AM in isododecane), sold under the name GEL BELSIL RG90 by Wacker.

[0089] The silicone crosspolymer may be dispersed in at least one oil. In certain embodiments, the oil may be chosen from silicone oils, such as cyclic and linear organopolysiloxanes. Cyclic organopolysiloxanes may include, for example, cyclotetrasiloxane; cyclopentasiloxane; and methylated cyclic organopolysiloxanes, for example, octamethylcyclotetrasiloxane and decamethylcyclopentasiloxane. Non- limiting examples of linear organopolysiloxanes include low molecular weight dimethicones; high molecular weight dimethicones; alkyl derivatives of linear organopolysiloxanes, for example, cetyl dimethicone and lauryl trimethicone; aryl derivatives of linear organopolysiloxanes, for example, phenyl trimethicone; and hydroxylated derivatives of linear organopolysiloxanes, for example, dimethiconol. In other embodiments, the oil may be chosen from organic oils, such as mineral oil; linear and branched alkanes, for example, isododecane; triethylhexanoin; and squalane. [0090] The at least one silicone crosspolymer may, in some embodiments, comprise from about 5% to about 35% by weight, relative to the total weight of the silicone elastomer blend, for example, from about 1 0% to about 20% by weight, or from about 25% to about 35% by weight, or from about 20% to about 30% by weight. The at least one oil may comprise from about 65% to about 95% by weight, relative to the total weight of the silicone elastomer blend, such as from about 80% to about 90% by weight, or from about 65% to about 75% by weight, or from about 70% to about 80% by weight.

[0091] In various exemplary embodiments, the silicone elastomer blend comprises from about 20% to about 30% of dimethicone/vinyl dimethicone cross- polymer. In further exemplary embodiments, the silicone elastomer blend comprises from about 70% to about 80% by weight of dimethicone.

[0094] The at least one silicone elastomer may optionally be included in the composition in an amount up to about 10%, such as up to about 8%, up to about 5%, about 4.5%, up to about 4%, up to about 3.5%, up to about 3%, up to about 2.5%, up to about 2%, up to about 1 .5%, up to about 1 %, up to about 0.75%, up to about 0.5%, up to about 0.25%, up to about 0.2%, or up to about 0.1 %, by weight, relative to the weight of the composition. In certain embodiments, the at least one silicone elastomer may be present in an amount ranging from about 1 % to about 10%, such as about 2% to about 8%, about 3% to about 6%, or about 4% to about 5%, by weight, relative to the weight of the composition.

Humectants

[0095] Optionally, compositions according to the disclosure may comprise at least one humectant or moisturizing agent. Surprisingly, in at least certain embodiments, the at least one humectant may improve the optical properties and feeling of the film formed on the skin by the composition, without negatively affecting the mechanical properties of the film.

[0096] By way of example only, humectants or moisturizing agents may be chosen from polyhydroxy compounds including but not limited to glycerin and glycols such as, for example, propylene glycol, butylene glycol, dipropylene glycol and diethylene glycol, glycol ethers such as monopropylene, dipropylene and

tripropylene glycol alkyl(CrC ₄ )ethers, monoethylene, diethylene and triethylene glycol.

[0097] The at least one humectant may be present in the composition in an amount up to about 20%, such as up to about 15%, up to about 14%, up to about 13%, up to about 12%, up to about 1 1 %, up to about 10%, up to about 9%, up to about 8%, up to about 7%, up to about 6%, up to about 5%, up to about 4%, up to about 3%, up to about 2%, up to about 1 %, or up to about 0.5%, by weight of the composition.

Water

[0098] Optionally, in at least certain embodiments, water may be added to the compositions according to the disclosure. Surprisingly, in certain non-limiting embodiments, water may improve the properties of the film formed on the skin by the composition, such as Young Modulus, transparency, cohesion, and thickness.

[0099] Water can be included in the composition in an amount up to about 15%, up to about 12%, up to about 10%, up to about 9%, up to about 8%, up to about 7%, up to about 6%, up to about 5%, up to about 4%, up to about 3%, up to about 2%, up to about 1 %, or up to about 0.5%, by weight of the composition. In at least certain embodiments, the compositions are anhydrous or substantially anhydrous. In other embodiments, the compositions may be in the form of a water- in-oil (W/O) emulsion.

[00100] It may, in at least certain embodiments, be advantageous to include water and at least one humectant, for example water and glycerin, in the composition together.

Film

[00101] When the compositions according to the disclosure are applied to the skin, the at least one thermoplastic elastomer, the at least one adhesive polymer, and the at least one filler together form a matrix that creates a film on the skin. The films formed by the compositions described herein form quickly, are long-lasting and durable, and have optical properties that are advantageous for hiding skin

imperfections, such as minimal thickness, good coverage of imperfections, a matte effect, and a soft focus effect which helps to blur skin imperfections so that they are less noticeable.

[00102] In various exemplary embodiments, for the best film properties, it may be advantageous for the total amount of thermoplastic elastomer plus adhesive polymer plus filler to be greater than about 10%, such as greater than about 15% or greater than about 20%, by weight, of the total weight of the composition.

[00103] In yet further exemplary embodiments, for the best film properties, it may be advantageous for amounts of the thermoplastic elastomer and adhesive polymer to be chosen so that the ratio of thermoplastic elastomenadhesive polymer is in the range of about 1 :10 to 10:1 , in the range of about 1 :5 to 5:1 , or in the range of about 1 :1 to 8:1 .

[00104] The films may be formed quickly, for example within less than about 30 minutes, less than about 20 minutes, less than about 10 minutes, or less than about 5 minutes, after the composition is applied to the skin.

[00105] Films according to the disclosure may be long-lasting. For example, once the composition is applied to the skin and a film is formed, the film may remain substantially intact on the skin for a period of at least about 6 hours, such as at least about 12 hours, at least about 24 hours, at least about 48 hours, or at least about 72 hours, unless the film is intentionally removed by the user.

[00106] The films may also be durable. For example, the film may not rub off, may not come off with sweat, or when the film is contacted by water, makeup, lotions, or other products that the user may wish to put on the skin.

[00107] The films may, in some embodiments, be nearly undetectable to the human eye. While pigments may be added, the pigments may optionally allow the film to have a coloration that is nearly identical to the skin, allowing the film to "blend in" with the skin. Additionally, the film is durable and thin enough to allow the user to apply the composition to skin imperfections to form a film thereon, and then go about a normal make-up routine without adversely affecting the film.

[00108] The films that are formed by the compositions described herein may have a Young Modulus of less than about 500kPa, less than about 400kPa, less than about 300kPa, less than about 250kPa, less than about 200kPa, less than about 150kPa, less than about l OOkPa, less than about 75kPa, or less than about 50kPa. As such, the films may be considered non-tightening, i.e. the films do not, or not significantly, have a feeling of contracting on the skin in order to reduce the appearance of wrinkles and eye bags. However, the films will still improve the appearance of the skin by hiding or blurring the appearance of skin imperfections, such as wrinkles, eyebags, pimples, pores, dark spots, etc.

Methods

[00109] Methods of improving the appearance of the skin are also disclosed, said methods comprising applying a composition according to the disclosure onto the skin in order to form a long-lasting film on the skin. Methods comprise blurring or hiding skin imperfections, e.g. to cover or camouflage pimples, pores, dark spots, etc.

[00110] It to be understood that, as used herein the terms "the," "a," or "an," mean "at least one," and should not be limited to "only one" unless explicitly indicated to the contrary. Thus, for example, reference to "a portion" includes examples having two or more such portions unless the context clearly indicates otherwise. [00111] Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not actually recite an order to be followed by its steps or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that any particular order be inferred.

[00112] While various features, elements or steps of particular embodiments may be disclosed using the transitional phrase "comprising," it is to be understood that alternative embodiments, including those that may be described using the transitional phrases "consisting" or "consisting essentially of," are implied. Thus, for example, implied alternative embodiments to a method that comprises A+B+C include embodiments where a method consists of A+B+C and embodiments where a method consists essentially of A+B+C. As described, the phrase "at least one of A, B, and C" is intended to include "at least one A or at least one B or at least one C," and is also intended to include "at least one A and at least one B and at least one C."

[00113] All ranges and amounts given herein are intended to include subranges and amounts using any disclosed point as an end point. 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, etc., are intended to be modified by the term "about," whether or not so expressly stated. Similarly, a range given of "about 1 % to 10%" is intended to have the term "about" modifying both the 1 % and the 10% endpoints.

[00114] It is understood that when an amount of a component is given, it is intended to signify the amount of the active material. [00115] It should be understood that all patents and published patent applications referenced are incorporated herein in their entireties.

[00116] Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term "about." Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure.

[00117] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors

necessarily resulting from the standard deviation found in their respective testing measurements. The example that follows serves to illustrate embodiments of the present disclosure without, however, being limiting in nature.

[00118] The compositions and methods according to the present disclosure can comprise, consist of, or consist essentially of the elements and limitations described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise known in the art.

[00119] It will be apparent to those skilled in the art that various modifications and variations can be made in the delivery system, composition and methods of the invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided that they come within the scope of the appended claims and their equivalents.

EXAMPLES

[00120] The following Examples are provided for illustrative purposes only, and are not intended to be limiting.

[00121] In each of the following examples, the amounts of components given are in terms of active material (AM).

Haze and Transparencv-BYK Haze-Guard

[00122] The film was made by using a draw down bar at 8" to cast the solution on a transparent plastic film and dried on bench for 3 hours. The BYK Haze-Guard instrument was used to measure the transparency and the haze of the film.

Transparency, Homogenizing Power and Whitening Power - Colorimeter MINOLTA

[00123] The film was made by casting the solution on a transparent plastic film using a draw down bar (2 mil) and left to dry on the bench for 1 hour. The Minolta colorimeter was used to measure the L, a ^* , b ^* and Y of the film, and of a skin tone sheet reference and black and white reference, in order to calculate the

transparency, homogenizing power, and whitening power of the films.

Wear and Coverage

[00124] The films were applied on the cheeks of 3 panelists with pimples and pores along nose/cheek area and left for 6 hours. Last was evaluated through before/after pictures. Shininess, pore hiding, imperfections coverage for times both before and after were evaluated. Example 1 : Compositions That Form Films

[00125] The thermoplastic elastomer, Kraton (25%), was dispersed in isoparaffin oil with a mechanical stirrer and heated to 90°C. Stirring continued at 90°C for 1 -2 hours until all Kraton polymer was dissolved and the polymer solution became clear. The desired amounts of oil dispersion (49% in isododecane), silica silylate, silicone elastomer (DC EL-8040 ID silicone organic blend at 18% isododecane), and pigments were added into the Kraton/isoparaffin oil solution at the specified ratios in a plastic container, and the solution was mixed with a high speed mixer at 2500 rpm/min for 5 minutes. The final solution was kept at room temperature and sealed to avoid the evaporation of solvents.

[00126] The following Table 1 shows the comparison of the formulations according to the disclosure with pigments, and films formed therefrom (Ex. 1 a; 1 b), and two comparative commercial formulations.

pimple hiding

[00127] The films were evaluated as described above. Ex. 1 a and 1 b are long- lasting and demonstrate a strong ability to hide more prominent skin imperfections, such as pimples. Both the Ex. 1 a and 1 b films show better results in hiding or blurring skin imperfections, while being longer-lasting, than either of the comparative commercial formulations.
