TITLE OF THE INVENTION

MATTE LI P COM POS ITIONS

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001 ] This application claims the benefit of priority from U.S. Serial No. 15/908,646, filed February 28, 2018, the entire contents of which is hereby incorporated by reference

FIELD OF THE INVENTION

[0002 ] The present invention relates to matte lip compositions comprising at least one siloxysilicate resin, at least one polyorganosiloxane copolymer, at least one lipophilic silica, at least one non-lipophilic filler and at least one non-volatile hydrocarbon oil, as well as to methods of making such compositions and methods of applying such compositions to lips.

DISCUSSION OF THE BACKGROUND

[0003] Many cosmetic compositions, including pigmented cosmetics such as lipsticks or lip colors, have been formulated in an attempt to possess long-wearing properties upon application.

Unfortunately, many of these compositions do not generally possess good long-wear/transfer-resistance properties as well as good appearance properties (for example, matte properties) and/or application properties.

[0004 ] With respect to lip compositions, commercial products containing silicon resins such as MQ resins are known. Such products are known to provide good long wear properties/transfer-resistance. However, such products possess poor application properties and/or poor feel upon application (for example, feels rough).

[0005 ] For example, U.S. patent 8,080,257, U.S. patent 7,758,848, U.S. application 2004/0170586, PCT application WO

2003/105801 , and PCT application WO 2010/105952, disclose

compositions containing nylon-611/dimethicone and MQ resins in broad, general amounts.

[0006] Typically, a second composition (topcoat) is separately applied to such products to improve poor properties of the compositions to make the products acceptable to consumers. However, topcoat compositions tend to decrease the long-wear/transfer-resistance properties of the lip compositions, thereby rendering the long-wear/transfer resistant composition less acceptable to consumers and less acceptable for their intended purpose.

[0007 ] Thus, there remains a need for improved matte lip compositions having improved cosmetic properties, particularly good transfer-resistance, feel and/or matte characteristics upon application.

SUMMARY OF THE INVENTION

[0014 ] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0015 ] As used herein, the expression "at least one" means one or more and thus includes individual components as well as

mixtures/combinations.

[0016] Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term“about,” meaning within 10% to 15% of the indicated number.

[0017 ] "Film former" or“film forming agent” as used herein means a polymer or resin that leaves a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/or dissipated on the substrate.

[0018 ] "Makeup Result" as used herein, refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time. “Makeup Result” may be evaluated by evaluating long wear properties by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to lips and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to lips and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.

[0019] Anhydrous refers to a composition not containing any water, that is to say a composition in which the water that may be present comes only from the water of crystallization or of adsorption of the starting materials. In any case, an“anhydrous composition” in accordance with the present invention contains less than 3% by weight of water, preferably less than 1 % by weight, and better still less than 0.5% by weight of water, relative to the total weight of the composition. A composition of the present invention may also contain no water.

[0020 ] "Transfer resistance" as used herein refers to the quality exhibited by compositions that are not readily removed by contact with another material, such as, for example, a glass, an item of clothing or the skin, for example, when eating or drinking. Transfer resistance may be evaluated by any method known in the art for evaluating such. For example, transfer resistance of a composition may be evaluated by a "kiss" test. The "kiss" test may involve application of the composition to human keratin material such as hair, skin or lips followed by rubbing a material, for example, a sheet of paper, against the hair, skin or lips after expiration of a certain amount of time following application, such as 2 minutes after application. Similarly, transfer resistance of a composition may be evaluated by the amount of product transferred from a wearer to any other substrate, such as transfer from the hair, skin or lips of an individual to a collar when putting on clothing after the expiration of a certain amount of time following application of the composition to the hair, skin or lips. The amount of composition transferred to the substrate (e.g., collar, or paper) may then be evaluated and compared. For example, a composition may be transfer resistant if a majority of the product is left on the wearer’s hair, skin or lips. Further, the amount transferred may be compared with that transferred by other compositions, such as commercially available compositions. In a preferred embodiment of the present invention, little or no composition is transferred to the substrate from the hair, skin or lips.

[0021 ] "Long wear" compositions as used herein, refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time. Long wear properties may be evaluated by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to human hair, skin or lips and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to hair, skin or lips and these characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available

compositions. For lip compositions,“long wear” typically means the composition remains on the lips at least about 4 hours up to about 24 hours, and retains rich color even after eating.

[0022 ] “Liquid” or“liquid cosmetic” or“liquid l ipstick” or “liquid com position” means a composition having a fixed volume, flows to cover the bottom and assumes the shape of the portion of the container it fills and is slightly compressible (as disclosed in General chemistry, Fourth Edition 2005, p.434).

[0023] “Adhesion” as used herein, refers to chemical or physical bonding between a coating and a substrate. Good adhesion between a lip composition and lips should translate to good wear properties on

consumers. Adhesion properties can be quantified by in-vitro method such as a cross-cut adhesion test. In the test, a lattice pattern is cut into the coating and penetrates through to the substrate. A pressure sensitive tape is applied to the sample and then pulled off. The adhesion property can be quantified by the area of the coating remaining after peeling. For example, if the whole film remains after peeling, it indicates excellent adhesion. If most of the film gets peeled off, it indicates poor adhesion. The cross-cut test is an industrial standard test for testing adhesion for coatings.

(Reference # ISO/DIN 2409, ASTM D3359).

[0024 ] “Substituted” as used herein, means comprising at least one substituent. Non-limiting examples of substituents for substitution include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as hydroxyl groups, ether groups, alkoxy groups, acyloxyalky groups, oxyalkylene groups, polyoxyalkylene groups, carboxylic acid groups, amine groups, acylamino groups, amide groups, halogen containing groups, ester groups, thiol groups, sulphonate groups, thiosulphate groups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.

[0025 ] “Volatile”, as used herein, means having a flash point of less than about 100°C.

[0026] “Non-volatile”, as used herein, means having a flash point of greater than about 100°C.

[0027 ] “Matte” in compositions as used herein refers to compositions having little to no light reflection. For example, matte compositions can have average gloss properties, measured at 60°, of less than or equal to 10, for example 9, preferably less than or equal to 8, 6, 5, 4 or 1 , including all ranges and subranges therebetween such as 1 -10, 1 -5, 2- 10, 3-8, less than 1 , less than 3, less than 5, etc.

[0028 ] “Free” or“substantially free” or“devoid of as it is used herein means that while it is preferred that no amount of the specific component be present in the composition, it is possible to have very small amounts of it in the compositions of the invention provided that these amounts do not materially affect at least one, preferably most, of the advantageous properties of the conditioning compositions of the invention. Thus, for example,“free of phenylated solvents” means that non-volatile solvents are preferably omitted (that is 0% by weight), but can be present in the composition at an amount of less than about 0.25% by weight, typically less than about 0.1 % by weight, typically less than about 0.05% by weight, based on the total weight of the composition as a whole.

[ 0029 ] The compositions and methods of the present invention can“comprise,”“consist of” or“consist essentially of” the essential elements and limitations of the invention described herein, as well as any additional or optional ingredients, components, or limitations described herein or otherwise useful. For purposes of the compositions and methods of the present invention where the invention’’consists essentially of” the identified ingredients and/or process steps, the sole“basic and novel property” of such compositions and/or methods is“matte.” Further, given that it is contemplated that other mattifying agents can be added to the invention methods and compositions in the context of the present invention, a “material effect” on the basic and novel property of the invention can only be an adverse effect. That is, because positive effects on matte properties (such as those effected by mattifying agents such as silica) are within the scope of the present invention, only ingredients which have a material adverse effect on matte properties of the invention compositions would be relevant to determining whether or not compositions or methods“consist essentially of the required elements.

[ 0030 ] The composition of the present invention may be in any form, either liquid or non-liquid (semi-solid, soft solid, solid, etc.). For example, it may be a paste, a solid, a gel, or a cream. It may be an emulsion, such as an oil-in-water or water-in-oil emulsion, a multiple emulsion, such as an oil-in-water-in-oil emulsion or a water-in-oil-in-water emulsion, or a solid, rigid or supple gel. The composition of the invention may, for example, comprise an external or continuous fatty phase. The composition can also be a molded composition or cast as a stick or a dish.

[0045 ] Lipophilic Silica

[0046] In accordance with the present invention, matte lip compositions comprising at least one lipophilic silica are provided. The term "lipophilic silica" means a silica that is capable of swelling in a lipophilic medium.

It is in fact possible to modify the surface of silica chemically, by a chemical reaction producing a decrease in the number of silanol groups present on the surface of the silica. The silanol groups can notably be replaced with hydrophobic groups: a lipophilic silica is then obtained. The hydrophobic groups can be, for example:

[0048 ] trimethylsiloxyl groups, which are notably obtained by treatment of pyrogenic silica in the presence of hexamethyldisilazane.

Silicas treated in this way are called "Silica silylate" according to the CTFA (6th edition, 1995). They are for example marketed under the references "AEROSIL R812®" by the company Degussa, "CAB-O-SIL TS-530®" by the company Cabot; and/or

[0049] dimethylsilyloxyl or polydimethylsiloxane groups, which are notably obtained by treatment of pyrogenic silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are called "Silica dimethyl silylate" according to the CTFA (6th edition, 1995). They are for example marketed under the references "AEROSIL R972®", "AEROSIL R974®" by the company Degussa, "CAB-O-SIL TS-610®", "CAB- O-SIL TS-720®" by the company Cabot.

[0050 ] Preferably, the lipophilic silica is present in the matte lip compositions of the present invention in amounts of active material generally ranging from about 0.5% to about 1.5%, and preferably from about 1 % to about 1.5%, by weight, based on the total weight of the composition, including all ranges and subranges in between.

[ 00133 ] The present invention will be better understood from the examples which follow. The examples are intended to be nonrestrictive and explanatory only, with the scope of the invention defined by the claims.

[ 00134 ] Example 1 - Evaluation Techniques

[ 00135 ] Compositions were evaluated for tack, finish (matte), flake, according to the following procedures:

[ 00136 ] Tack: Films of compositions tested were deposited onto contrast cards using a 3 MIL drawdown bar and an Automatic Drawdown Machine. The films were dried at room temperature (25 ° C) overnight and analyzed using a Texture Analyzer equipped with a ball probe. Tack force was measured after applying 350 g-force for 10 seconds. Then, the values of the tackiness were correlated to the comfort of wear of the tested products. The samples having tackiness values higher than 100 gr/force, were considered to be very uncomfortable to wear. The tack values between 50-100 gr/force, indicated medium comfort, and those with values of less than 50 gr/force were considered to be comfortable. In accordance with this testing, compositions of the present invention preferably have tack values of 50 gr/force or less, preferably 45 gr/force or less, preferably 35 gr/force or less, and preferably 25 gr/force or less.

[ 00137 ] In vitro Shine: Films of compositions tested were deposited onto BLACK SCRUB PANEL P121 -10N using a 1 MIL drawdown bar and an Automatic Drawdown Machine. The films were dried at room temperature for 5 minutes and analyzed using a gloss meter (BYK: micro- TRI-gloss) at an angle of 60°. [00138 ] Flake: Samples were tested for flake resistant properties. Samples of all tested compositions were deposited onto polyurethane white bioskin using a 3 MIL drawdown bar. The samples were allowed to dry overnight at room temperature (25 ° C) and then they were stretched by pulling from two sides. During the stretching process, flaking of the dry samples was observed and correlated with durability of wear of the tested products. To define the degree of samples’ flaking, the following four (5) point grading scale was used: 1 - no flaking (very good wear), 2 - low flaking (good wear), 3 - medium flaking (medium/acceptable wear), 4- high flaking (no wear) and 5- fail (no wear).

[00139] Separation (lack of stability): Compositions were hand mixed and 6mL transferred into a 15mL plastic centrifuge tube. The samples were centrifuged for 25 minutes at 2800G (Themo Electron

Corporation IEC C130 Centrifuge). Percent separation was calculated using the equation % separation = [(XmL separated transparent liquid)/6mL] X 100.

[00140 ] Example 2 - Composition Preparation

[00141 ] Compositions were prepared by the following procedure: Pigment, isododecane and MQ resin were ground to create a pigment paste. The paste was processed using Disconti Mill until it passed the Hegman Gauge test (ASTM D1210-05). Then, the paste was added to the remaining ingredients. The mixture was heated to 80 °C and stirred, until a homogeneous liquid composition was obtained. After that, the composition was cooled down to the room temperature and transferred to desired containers and/or applicators. [00142 ] Example 3 -- Comparative Testing

[00143] Different amounts of siloxysilicate resin (trimethylsiloxysilicate), polyorganosiloxane copolymer (nylon

611/dimethicone copolymer), lipophilic silica (silica silylate), non-lipophilic filler, and non-volatile hydrocarbon oil (polybutene) were evaluated in a base lip composition to prepare both invention and comparative
