Cosmetic compositions

TECHNICAL FIELD

[0002] The invention is in the field of cosmetic compositions for application to keratinous surfaces, and including but not limited to long wearing and/or transfer resistant cosmetic compositions.

BACKGROUND OF THE INVENTION

[0003] Long wearing cosmetic compositions are becoming more and more desirable. Women today are very busy and do not have the time or inclination to frequently reapply makeup. Transfer resistant cosmetics are a sub-category of long wearing cosmetics, and are cosmetic products that exhibit particularly strong affinity for keratinous surfaces, generally resisting the tendency to blot off the surface while undergoing normal activities. Many long wearing, and most transfer resistant compositions contain volatile ingredients which are critical to achieving the long wearing benefit. In most transfer resistant cosmetic compositions the volatile oils are linear or cyclic silicones or paraffinic hydrocarbons. While these types of volatile silicones and hydrocarbons work very well in promoting transfer resistance in the compositions in which they are used, they do have certain drawbacks. For example, volatile paraffinic hydrocarbons can leave a greasy residue on skin or lips, and are not always the best solvents for the film forming polymers used in such cosmetics. Volatile silicones are also excellent in promoting the transfer resistant properties of cosmetics in which they are used, but their drawbacks include incompatibility with certain film forming polymers, and higher cost. In addition the very high flash points of some volatile silicones make them evaporate very quickly, which causes problems during the manufacturing step as well as in storage of the resulting product.

[0004] Accordingly, there is a need for different solvents for use in promoting the long wearing and/or transfer resistant properties of cosmetic compositions.

[0005] It is an object of the invention to provide long wearing and/or transfer resistant cosmetic compositions containing solvents other than volatile silicones or volatile paraffinic hydrocarbons that promote the long wearing and/or transfer resistant properties of the compositions.

[0006] It is also an object of the invention to provide a long wearing or transfer resistant cosmetic composition wherein a portion of the volatile silicone or paraffinic hydrocarbon normally present is substituted with a transfer resistant promoting solvent that is not a silicone or paraffinic hydrocarbon.

[0007] It is a further object of the invention to provide long wearing and/or transfer resistant compositions wherein the volatile component contributing to the transfer resistant and/or long wearing property comprises an ingredient containing at least one alkyl ether group bonded to a short chain alcohol or alcohol ester.

[0008] It is a further object of the invention to provide cosmetic compositions comprising at least one ingredient containing an alkyl ether group bonded to a short chain alcohol or alcohol ester.

SUMMARY OF THE INVENTION

[0009] The invention comprises long wearing and/or transfer resistant cosmetic compositions wherein at least a portion of the long wearing or transfer resistant property is provided by volatile silicones or volatile paraffinic hydrocarbons, the improvement wherein at least some of the volatile silicone or volatile paraffinic hydrocarbon is replaced with an organic solvent containing at least one alkyl ether group bonded to at least one short chain alcohol or alcohol ester.

[0010] The invention further comprises a method for improving the wear, feel, application, and other aesthetic properties of long wearing cosmetic compositions wherein the long wearing property is achieved, at least in part, by use of volatile silicones or volatile paraffinic hydrocarbons, by substituting at least a portion of the volatile silicone or volatile paraffinic hydrocarbon with an organic solvent containing at least alkyl ether group bonded to at least one short chain alcohol or alcohol ester.

[0011] Another embodiment of the invention comprises a cosmetic composition, preferably a pigmented cosmetic composition, comprising at least one ingredient containing an alkyl ether group bonded to at least one short chain alcohol or alcohol ester.

DETAILED DESCRIPTION

[0012] All percentages mentioned herein shall be percentages by weight unless otherwise indicated.

[0013] In one embodiment, the compositions of the invention are long wearing or transfer resistant cosmetic compositions wherein the long wearing or transfer resistant property of the composition is imparted, at least in part, by the presence of volatile silicones and/or volatile hydrocarbons. The compositions may be anhydrous or in the emulsion form, and may be lipsticks, foundation makeup, blush, eyeshadow, concealer, mascara, skin lotions, creams, and the like. The compositions may be in the liquid, solid, or semi-solid form. Most preferably the compositions are lipsticks.

[0014] Another embodiment of the invention is directed to cosmetic compositions, preferably pigmented cosmetic compositions, which comprise at least one ingredient containing an alkyl ether group bonded to at least one short chain alcohol or alcohol ester.

[0015] The term “transfer resistant” means that the composition, when applied to the keratinous surface, exhibits a reduced tendency to transfer from that surface onto another surface such as the back of the hand or a tissue when that other surface is placed into contact with the keratinous surface having the cosmetic composition applied thereto.

[0016] The term “long wearing” means that the composition, when applied to the keratinous surface, stays on the surface for a longer period of time.

[0017] The term “keratinous surface” means, in the context of this invention, skin (including lips), hair, or nails; most preferably skin and lips.

[0018] I. The Compositions of the Invention

[0019] The various types of ingredients that may be found in the cosmetic compositions of the invention are further described herein.

[0020] A. The Organic Component

[0021] In one embodiment of the cosmetic compositions of the invention, the volatile silicone or volatile paraffinic hydrocarbon that is present to contribute to the transfer resistant and/or long wearing properties is at least partially, possibly completely, replaced with an organic solvent comprised of one or more organic compounds containing at least one alkyl ether group bonded to at least one short chain alcohol or alcohol ester. Even though at least a portion of the volatile silicone or volatile paraffinic hydrocarbon normally present in the composition has been removed and substituted with the organic solvent, the composition still retains its transfer resistant and/or long wearing characteristics. In fact, the organic component is as effective as the volatile silicone or volatile paraffinic hydrocarbon in contributing to the long wearing or transfer resistant properties of the composition.

[0022] In another embodiment of the invention, the cosmetic composition comprises at least one or more organic compounds or solvents containing at least one alkyl ether group bonded to at least one short chain alcohol or alcohol ester. The composition may any type of cosmetic composition, and not necessarily long wearing or transfer resistant.

[0023] Preferably, the organic compound or solvent is volatile or near volatile. The term “volatile” means that the organic solvent has a vapor pressure of at least about 2 mm. of mercury at 20° C. The term “near volatile” means that the organic solvent has a vapor pressure ranging from about 1.0 to 2 mm of mercury at 20° C. The organic solvent may be present alone or in a mixture of compounds. Preferably the viscosity of the solvent or mixture ranges from about 0.1-12 centipoise, preferably about 0.3-8 centipoise, more preferably about 0.5-5 centipoise at room temperature (25° C.).

[0025] The alkyl ether group is bonded to at least one short chain alcohol or alcohol ester. The short chain alcohol may be a mono-, di-, or polyhydric alcohol. The term “short chain” when used in conjunction with “alcohol” means an alcohol having 1, 2, 3, 4, 5, or 6 carbon atoms. Examples of short chain alcohols are methanol, ethanol, propanol, butanol, pentanol, hexanol, which may be substituted with one or more hydroxyl groups.

[0026] Suitable alcohol esters are short chain alcohols (as defined above) that are esterified with carboxylic acids having 1, 2, 3, 4, 5, or 6 carbon atoms. The carboxylic acids may also be substituted with one or more hydroxyl groups.

[0027] A wide variety of organic compounds suitable for use in place of the volatile silicone or volatile paraffinic hydrocarbons, or suitable for use in the cosmetic compositions of the invention in general whether long wearing or not, can be identified by simply combining one or more such alkyl ether groups with one or more of such short chain alcohols or alcohol esters.

[0029] B. Volatile Silicones or Volatile Paraffinic Hydroccarbons

[0030] In one embodiment of the invention, the organic compound is used to replace at least some, possibly all of the volatile silicones or volatile paraffinic hydrocarbons that may be present in the composition. In the event the organic compound is used to partially replace the volatile silicones or paraffinic hydrocarbons present, the composition may contain such materials. Examples of suitable volatile silicones or paraffinic hydrocarbons that may be present include:

[0031] 1. Volatile Silicones

[0032] Cyclic silicones are of the general formula:

[0033] where n=3-6.

[0034] Linear volatile silicones in accordance with the invention have the general formula:

Examples of suitable volatile paraffinic hydrocarbons include isohexadecane, isododecane, or mixtures thereof.

[0039] C. Pigments and Powders

[0040] The composition may also comprise a variety of particulates including pigments, powders, and mixtures thereof. Suggested ranges of such ingredients are about 0.05-70%, preferably about 0.1-25%, more preferably about 0.5-20% by weight of the total composition.

[0041] Suitable pigments may be organic or inorganic. Examples of organic pigments include red, green, blue, yellow, violet, orange, and mixtures thereof. Also suitable are Lakes of such pigments, which means that the organic pigments are reacted with a metal salt such as calcium, aluminum, barium, zirconium, and the like to form salts. Preferred are aluminum Lakes of the organic pigments, which is where the organic pigment is reacted with aluminum to form the aluminum salt. Formation of the metal salt of the organic pigment will generally also convert the pigment from a water soluble pigment into a water insoluble pigment, and such pigments tend to become lipophilic in nature, meaning that they will exhibit affinity for lipophilic or oily ingredients in the composition. Examples of organic pigment families that may be used herein include azo, (including monoazo and diazo), fluoran, xanthene, indigoid, triphenylmethane, anthroquinone, pyrene, pyrazole, quinoline, quinoline, or metallic salts thereof. Preferred are D&C colors, FD&C colors, or Lakes of D&C or FD&C colors. The term “D&C” means drug and cosmetic colors that are approved for use in drugs and cosmetics by the FDA. The term “FD&C” means food, drug, and cosmetic colors that are approved for use in foods, drugs, and cosmetics by the FDA. Certified D&C and FD&C colors are listed in 21 CFR 74.101 et seq. and include the FD&C colors Blue 1, Blue 2, Green 3, Orange B, Citrus Red 2, Red 3, Red 4, Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2; Orange B, Citrus Red 2; and the D&C colors Blue 4, Blue 9, Green 5, Green 6, Green 8, Orange 4, Orange 5, Orange 10, Orange 11, Red 6, Red 7, Red 17, Red 21, Red 22, Red 27, Red 28, Red 30, Red 31, Red 33, Red 34, Red 36, Red 39, Violet 2, Yellow 7, Yellow 8, Yellow 10, Yellow 11, Blue 4, Blue 6, Green 5, Green 6, Green 8, Orange 4, Orange 5, Orange 10, Orange 11, and so on. Suitable Lakes of D&C and FD&C colors are defined in 21 CFR 82.51. Particularly preferred are Lakes formed by the reaction of the organic pigment with a metallic salt such as aluminum, calcium, zirconium, barium, and the like. Suitable reds include pigments from the monoazo, disazo, fluoran, xanthene, or indigoid families or Lakes thereof, such as Red 4, 6, 7, 17, 21, 22, 27, 28, 30, 31, 33, 34, 36, and Red 40. Also suitable are Lakes of such red pigments. Typically the metal salts are aluminum, barium, and the like. Most preferred are Aluminum Lakes of the various red pigments mentioned herein.

[0042] Suitable yellows include wherein the yellow pigment is a pyrazole, monoazo, fluoran, xanthene, quinoline, or salt thereof. Suitable yellows include Yellow 5, 6, 7, 8, 10, and 11, as well as Lakes of such yellow pigments.

[0043] Suitable violets include those from the anthroquinone family, such as Violet 2 and Lakes thereof. Examples of orange pigments are Orange 4, 5, 10, 11, or Lakes thereof.

[0044] Also suitable are inorganic pigments that include iron oxides such as red, blue, black, green, and yellow; titanium dioxide, bismuth oxychloride, and the like. Preferred are iron oxides.

[0045] It may also be desirable to include one or more particulate fillers in the claimed composition. If so, suggested ranges are about 0.001-40%, preferably about 0.05-35%, more preferably about 0.1-30% by weight of the total composition. Preferably, the particulate fillers include non-pigmentitious particles that generally have a particle size ranging from about 0.02 to 200, preferably 0.5 to 100, microns. Suitable particle fillers include titanated mica, fumed silica, spherical silica, polymethylmethacrylate, micronized teflon, boron nitride, mica, acrylate copolymers, aluminum silicate, aluminum starch octenylsuccinate, bentonite, calcium silicate, cellulose, chalk, corn starch, diatomaceous earth, fuller's earth, glyceryl starch, hectorite, hydrated silica, kaolin, magnesium aluminum silicate, magnesium trisilicate, maltodextrin, montmorillonite, microcrystalline cellulose, rice starch, silk powder, silica, talc, mica, zinc laurate, zinc myristate, zinc rosinate, alumina, attapulgite, calcium carbonate, calcium silicate, dextran, kaolin, nylon, silica silylate, sericite, soy flour, tin oxide, titanium hydroxide, trimagnesium phosphate, walnut shell powder, or mixtures thereof. The particulates may also be in the fiber form, such as cellulose fibers, rayon fibers, nylon or silk fibers and the like. Such fibers are generally circular in cross-section and have a discernable length. Preferably the length ranges from 1 to 5 mm.

[0046] The above mentioned pigments, powders or fibers may be inherently lipophilic or hydrophilic. The term “lipophilic” when used in this context means that the particulates will exhibit an affinity for lipophilic ingredients, or will be soluble or dispersible in lipophilic ingredients such as nonpolar oils. The term “hydrophilic” when used in this context means that the particulates exhibit an affinity for, or are soluble or dispersible in, water. For example, many types of organic pigments are hydrophilic and will be soluble or dispersible in water. On the other hand, in some cases, if the organic pigments are reacted with metal salts to form Lakes, in some cases the pigments will then exhibit a more lipophilic character. In the compositions of the invention, the pigments may be inherently lipophilic or inherently hydrophilic, depending on the properties desired. Further, if the pigments, particles or fibers are hydrophilic or if it is desired to increase their already lipophilic character, it may be desired to further surface treat the particulates with lecithin, amino acids, mineral oil, silicone oil or various other agents either alone or in combination, which coat the particulate surface and render the particles more lipophilic in nature. The term “lipophilic” means that the pigment or particles will be compatible with the lipophilic or oily phase of the composition. In the case of an emulsion, a lipophilic particle will have an affinity for the oily phase of the emulsion.

[0047] In the most preferred embodiment of the invention the composition comprises a mixture of organic or inorganic pigments in combination with non-pigmentitious particulates. Such pigments may be hydrophilic or lipophilic in character.

[0048] D. Film Forming Polymers

[0049] The composition may also comprise one or more film forming polymers. If so, suggested ranges are from about 0.01-90%, preferably about 0.5-80%, more preferably about 1-70% by weight of the total composition. A variety of film forming polymers are suitable including silicones, copolymers of silicone and organic moieties, and various types of organic synthetic polymers. Examples of such polymers are further described below.

[0050] 1. Silicone Film Forming Polymers

[0051] (a) Siloxane Polymeric Resins and Gums

[0052] Siloxane polymeric resins that comprises tetrafunctional or trifunctional units either alone or in combination with monofunctional units are suitable silicone film forming polymers. The term “siloxane polymeric resin” means that the siloxane is a polymer, or is comprised of repeating units or “mers”.

[0053] The term “resin” means that the siloxane polymer provides substantive, resinous, film forming properties when applied to skin. In the context of this invention, the term “resin” will mean a siloxane containing enough cross-linking to provide substantive, film forming properties. The term cross-linking means a moiety where the silicon atom is bonded to at least three, preferably four oxygen atoms when the moiety is polymerized with another siloxane unit.

[0054] The term “film forming” means that the siloxane resin is capable of forming a film, in particular, a substantive film, on the keratinous surface to which it is applied.

[0055] The term monofunctional unit means a siloxy unit that contains one silicon atom bonded to one oxygen atom, with the remaining three substituents on the silicon atom being other than oxygen. In particular, in a monofunctional siloxy unit, the oxygen atom present is shared by 2 silicon atoms when the monofunctional unit is polymerized with one or more of the other units. In silicone nomenclature used by those skilled in the art, a monofunctional siloxy unit is designated by the letter “M”, and means a unit having the general formula:

R1R2R3SiOl/2

[0056] wherein R1, R2, and R3 are each independently C1-30, preferably C1-10, more preferably C1-4 straight or branched chain alkyl, which may be substituted with phenyl or one or more hydroxyl groups; phenyl; alkoxy (preferably C1-22, more preferably C1-6); or hydrogen. The SiO1/2 designation means that the oxygen atom in the monofunctional unit is bonded to, or shared, with another silicon atom when the monofunctional unit is polymerized with one or more of the other types of units. For example, when R1, R2, and R3 are methyl the resulting monofunctional unit is of the formula:

[0057] When this monofunctional unit is polymerized with one or more of the other units the oxygen atom will be shared by another silicon atom, i.e. the silicon atom in the monofunctional unit is bonded to ½ of this oxygen atom.

[0058] The term “difunctional siloxy unit” is generally designated by the letter “D” in standard silicone nomenclature. If the D unit is substituted with substituents other than methyl the “D”designation is sometimes used, which indicates a substituent other than methyl. For purposes of this disclosure, a “D” unit has the general formula:

R1R2SiO2/2

[0059] wherein R1 and R2 are defined as above. The SiO2/2 designation means that the silicon atom in the difunctional unit is bonded to two oxygen atoms when the unit is polymerized with one or more of the other units. For example, when R1, R2, are methyl the resulting difunctional unit is of the formula:

[0060] When this difunctional unit is polymerized with one or more of the other units the silicon atom will be bonded to two oxygen atoms, i.e. will share two one-halves of an oxygen atom.

[0061] The term “trifunctional siloxy unit” is generally designated by the letter “T” in standard silicone nomenclature. A “T” unit has the general formula:

R1SiO3/2

[0062] wherein R1 is as defined above. The SiO3/2 designation means that the silicon atom is bonded to three oxygen atoms when the unit is copolymerized with one or more of the other units. For example when R1 is methyl the resulting trifunctional unit is of the formula:

[0063] When this trifunctional unit is polymerized with one or more of the other units, the silicon atom shares three oxygen atoms with other silicon atoms, i.e. will share three halves of an oxygen atom.

[0064] The term “tetrafunctional siloxy unit” is generally designated by the letter “Q” in standard silicone nomenclature. A “Q” unit has the general formula:

SiO4/2

[0065] The SiO4/2 designation means that the silicon shares four oxygen atoms (i.e. four halves) with other silicon atoms when the tetrafunctional unit is polymerized with one or more of the other units. The SiO4/2 unit is best depicted as follows:

[0066] The film forming siloxane resins that may be used in the compositions of the invention comprises D, T or Q units either alone or in combination with M units. In addition, there may be one or more of the other types of units present in the polymer.

[0067] The film forming polymeric siloxane resin may be a liquid, semi-solid, or solid at room temperature.

[0068] Typically T or MT silicones are referred to as silsesquioxanes, and in the case where M units are present methylsilsesquioxanes. Preferred are T silicones having the following general formula:

(R1SiO3/2)x

[0069] where x ranges from about 1 to 100,000, preferably about 1-50,000, more preferably about 1-10,000, and wherein R1 is as defined above. Such MT silicones are generally referred to as polymethylsilsesquioxane which are silsesquioxanes containing methyl groups.

[0070] Examples of specific polysilsesquioxanes that may be used are manufactured by Wacker Chemie under the Resin MK designation. This polysilsesquioxane is a polymer comprise of T units and, optionally one or more D (preferably dimethylsiloxy) units. This particularly polymer may have ends capped with ethoxy groups, and/or hydroxyl groups, which may be due to how the polymers are made, e.g. condensation in aqueous or alcoholic media. Other suitable polysilsesquioxanes that may be used as the film forming polymer include those manufactured by Shin-Etsu Silicones and include the “KR” series, e.g. KR-220L, 242A, and so on. These particular silicone resins may contain endcap units that are hydroxyl or alkoxy groups which may be present due to the manner in which such resins are manufactured.

[0071] Also suitable are MQ resins, which are siloxy silicate polymers having the following general formula:

[(RR′R″)3SiO1/2]x[SiO2]y

[0072] wherein R, R′ and R″ are each independently a C1-10 straight or branched chain alkyl or phenyl, and x and y are such that the ratio of (RR′R″)3SiO1/2 units to SiO2 units ranges from about 0.5 to 1 to 1.5 to 1. Preferably R, R′ and R″ are a C1-6 alkyl, and more preferably are methyl and x and y are such that the ratio of (CH3)3SiO1/2 units to SiO2 units is about 0.75 to 1. Most preferred is this trimethylsiloxysilicate containing 2.4 to 2.9 weight percent hydroxyl groups which is formed by the reaction of the sodium salt of silicic acid, chlorotrimethylsilane, and isopropyl alcohol. The manufacture of trimethylsiloxysilicate is set forth in U.S. Pat. Nos. 2,676,182; 3,541,205; and 3,836,437, all of which are hereby incorporated by reference. Trimethylsiloxysilicate as described is available from GE Silicones under the tradename SR-1000, which is a solid particulate material. Also suitable is Dow Corning 749 which is a mixture of volatile cyclic silicone and trimethylsiloxysilicate.

[0073] The film forming siloxane polymeric resins that may be used in the composition are made according to processes well known in the art. In general siloxane polymers are obtained by hydrolysis of silane monomers, preferably chlorosilanes. The chlorosilanes are hydrolyzed to silanols and then condensed to form siloxanes. For example, Q units are often made by hydrolyzing tetrachlorosilanes in aqueous or aqueous/alcoholic media to form the following:

[0074] The above hydroxy substituted silane is then condensed or polymerized with other types of silanol substituted units such as:

[0075] wherein n is 0-10, preferably 0-4.

[0076] Because the hydrolysis and condensation may take place in aqueous or aqueous/alcoholic media wherein the alcohols are preferably lower alkanols such as ethanol, propanol, or isopropanol, the units may have residual hydroxyl or alkoxy functionality as depicted above. Preferably, the resins are made by hydrolysis and condensation in aqueous/alcoholic media, which provides resins that have residual silanol and alkoxy functionality. In the case where the alcohol is ethanol, the result is a resin that has residual hydroxy or ethoxy functionality on the siloxane polymer. The silicone film forming polymers used in the compositions of the invention are generally made in accordance with the methods set forth in Silicon Compounds (Silicones), Bruce B. Hardman, Arnold Torkelson, General Electric Company, Kirk-Othmer Encyclopedia of Chemical Technology, Volume 20, Third Edition, pages 922-962, 1982, which is hereby incorporated by reference in its entirety.

[0077] Also suitable are linear, high molecular weight silicones that are semi-solids, solids, or gums at room temperature. Examples of such silicones include dimethicones having viscosities ranging from about 100,000 to 10 million, or 500,000 to 10 million centipoise or dimethicone copolyols having the same viscosity range.

[0078] Also suitable are silicone esters as disclosed in U.S. Pat. No. 4,725,658 and U.S. Pat. No. 5,334,737, which are hereby incorporated by reference. Such silicone esters comprise units of the general formula RaREbSiO[4−(a+b)/2] or R13xREySiOl/2, wherein R and R13 are each independently an organic radical such as alkyl, cycloalkyl, or aryl, or, for example, methyl, ethyl, propyl, hexyl, octyl, decyl, aryl, cyclohexyl, and the like, a is a number ranging from 0 to 3, b is a number ranging from 0 to 3, a+b is a number ranging from 1 to 3, x is a number from 0 to 3, y is a number from 0 to 3 and the sum of x+y is 3, and wherein RE is a carboxylic ester containing radical. Preferred RE radicals are those wherein the ester group is formed of one or more fatty acid moieities (e.g. of about 2, often about 3 to 10 carbon atoms) and one or more aliphatic alcohol moieities (e.g. of about 10 to 30 carbon atoms). Examples of such acid moieties include those derived from branched-chain fatty acids such as isostearic, or straight chain fatty acids such as behenic. Examples of suitable alcohol moieties include those derived from monohydric or polyhydric alcohols, e.g. normal alkanols such as n-propanol and branched-chain etheralkanols such as (3,3,3-trimethylolpropoxy)propane. Preferably the ester subgroup (i.e. the carbonyloxy radical) will be linked to the silicon atom by a divalent aliphatic chain that is at least 2 or 3 carbon atoms in length, e.g. an alkylene group or a divalent alkyl ether group. Most preferably that chain will be part of the alcohol moiety, not the acid moiety. Such silicones may be liquids or solids at room temperature.

[0079] (b). Copolymers of Silicone and Ethylenically Unsaturated Monomers

[0080] Another type of film forming polymer that may be used in the compositions of the invention is obtained by reacting silicone moieties with ethylenically unsaturated monomers. The resulting copolymers may be graft or block copolymers. The term “graft copolymer” is familiar to one of ordinary skill in polymer science and is used herein to describe the copolymers which result by adding or “grafting” polymeric side chain moieties (i.e. “grafts”) onto another polymeric moiety referred to as the “backbone”. The backbone may have a higher molecular weight than the grafts. Thus, graft copolymers can be described as polymers having pendant polymeric side chains, and which are formed from the “grafting” or incorporation of polymeric side chains onto or into a polymer backbone. The polymer backbone can be a homopolymer or a copolymer. The graft copolymers are derived from a variety of monomer units.

[0081] One type of polymer that may be used as the film forming polymer is a vinyl-silicone graft or block copolymer having the formula:

[0082] wherein G5 represents monovalent moieties which can independently be the same or different selected from the group consisting of alkyl, aryl, aralkyl, alkoxy, alkylamino, fluoroalkyl, hydrogen, and -ZSA; A represents a vinyl polymeric segment consisting essentially of a polymerized free radically polymerizable monomer, and Z is a divalent linking group such as C1-10 alkylene, aralkylene, arylene, and alkoxylalkylene, most preferably Z methylene or propylene.

[0083] G6 is a monovalent moiety which can independently be the same or different selected from the group consisting of alkyl, aryl, aralkyl, alkoxy, alkylamino, fluoroalkyl, hydrogen, and -ZSA;

[0084] G2 comprises A;

[0085] G4 comprises A;

[0086] R1 is a monovalent moiety which can independently be the same or different and is selected from the group consisting of alkyl, aryl, aralkyl, alkoxy, alkylamino, fluoroalkyl, hydrogen, and hydroxyl; but preferably C1-4 alkyl or hydroxyl, and most preferably methyl.
