Description:
A WATER IN OIL EMULSION PROVIDING SKIN MATTITY AND TRUE COLOR

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims the benefit of priority under 35 U.S.C. § 1 19(e) from U.S. Serial No. 62/415, 100, filed October 31 , 2016. The entire contents of which is hereby incorporated by reference.

[0002] TECHNICAL FIELD

[0003] The present invention relates to a water-in-oil cosmetic composition having at least one hydrophobically treated powder and at least two mattifying powders. Cosmetic compositions according to the invention impart true color and prolonged mattity, while also reducing dullness, whiteness, and/or ashiness of the keratinous substrate to which they have been applied, in particular skin. These compositions are particularly useful as foundations for deeper (darker) skin tones.

[0004] BACKGROUND OF THE INVENTION

[0005] Foundations are known and used in the cosmetic field to impart even color to the skin. It is also known that foundations can help to control oil and shine on the skin. However, when preparing foundations for deeper ethnic skin tones, and especially in the case of oil-absorbing and/or matte compositions, it has been found that such compositions tend to impart an undesirable, dull or ashy hue to darker skin. It is related to the whitening effect of fillers that are typically used to overcome opaqueness of the cosmetic compositions.

[0006] Polymeric and mineral fillers as well as starches are well-known in the cosmetic field. Such fillers and starches are generally incorporated into cosmetic compositions as oil-absorptive components which tend to have good adherence to the skin and contribute to the matte properties of the compositions. However, the use of fillers and starches in compositions can tend to give the user an undesirable ashy and/or dull appearance and may, in some cases, result in a dry skin feel. Moreover, the amount of fillers/starch necessary to adequately absorb oil and prevent shine generally also tends to whiten the formulation and give the ashy dull hue that becomes more apparent after the composition dries on the skin. In addition, the color of foundations applied to the skin changes over time and does not represent the initial shade. These problems are greatly exacerbated in the case of foundations for women with deeper ethnic skin tones.

[0007] Thus, there remains a need in the cosmetic industry to provide consumers having deeper ethnic skin tones with cosmetic products having improved properties such as improved oil absorption, shine reduction, wear of mattity, matte, texture, long-wear properties, and/or ability to impart true color, while also reducing dullness, whiteness, and/or ashiness of the skin.

[0008] The current inventive compositions are water-in-oil emulsions containing at least one hydrophobically treated powder, for example, pigments, as well as other powders providing enhanced oil absorption, long mattity, shine control and long wear. The compositions have good product application and coverage, and quickly transition to a powder upon application to a keratinous material, such as skin, retaining oil and shine-control properties.

[0009] SUMMARY OF THE INVENTION

[00017] 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.

[00018] DETAILED DESCRIPTION OF THE INVENTION

[00019] The aim of the present invention is to provide a water-in-oil emulsion which has good stability, while at the same time retaining good cosmetic properties. In particular, it is desired to provide a stable water-in-oil emulsion comprising at least one hydrophobically treated powder, pigments in particular, which are more typically used in oil-in-water emulsions.

[00020] The cosmetic compositions of the present invention are preferably water-in-oil emulsions, which contain low amount of water (less than about 30%) and have a high powder load (greater than 10% total powders). These compositions provide a unique texture in that they are initially creamy and light, affording good spreadability (increased product pick up and coverage) and also feel less drying. The compositions impart true and over time unvarying color while reducing the appearance of ashiness, whiteness, and/or dullness of the skin, which is especially useful for individuals having deeper ethnic skin tones. In addition, the inventive compositions have lasting mattifying effect.

[00021] These compositions are stable at accelerated conditions, as well as they have a long shelf life (stable longer than two (2) months).

[00022] In the following description of the invention and the claims appended hereto, it is to be understood that the terms used have their ordinary and accustomed meanings in the art, unless otherwise specified.

[00023] It is also 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, the use of "an oil absorbing powder" is intended to mean at least one oil absorbing powder.

[00024] "About" as used herein means within 10% of the indicated number (e.g.

"about 10%" means 9% - 1 1 % and "about 2%" means 1 .8% - 2.2%). [00025] The terms "ashy," "ashiness" and variations thereof are intended to refer to the appearance of a gray overcast on the skin or keratinous substrate after the product has been applied and evaluated after drying.

[00026] The term "deeper ethnic skin tones" is intended to refer to those skin tones that are darker and tend to have more pronounced and deeper red, red/yellow, and yellow undertones. Users with deeper ethnic skin tones may belong to ethnicities including, but not limited to, African, African-American, Caribbean, Hispanic, Middle Eastern, and Indian ethnicities.

[00027] "Free" or "devoid" 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 compositions of the invention. Thus, for example, "free of X" means that X is 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.

[00028] " L iqu id" or " l iq u id cosmetic" or " l iqu id foundat ion" or " l iqu id com pos ition" m eans 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.

[00029] "Water- in -oil emulsion" means a colloidal dispersion in which small droplets of the water phase (discontinuous phase) are dispersed within the oil phase (continuous phase).

[00030] "Matte", as used in foundation means that the composition is not shiny, shimmery or wet looking. Rather, it is powdery looking. "Good wear of mattity" or "mattity" refers to a product/composition's ability to maintain a matte skin appearance and/or feel throughout a period of time, such as a day or the consumer's normal wear time for the product.

[00031] The term "true color" is intended to refer to a color or shade that is most accurate or closest to the tone of the keratinous substrate to which it is applied. For instance, in at least certain exemplary embodiments, a composition that imparts true color according to the disclosure closely matches the skin tone without leaving an ashy, dull, white, and/or gray appearance. True color refers to the color obtained not only upon application to the keratinous substrate, but also after drying and wearing the composition over time (from least about 4 hours up to about 24 hours of wear).

[00032] "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 reevaluated 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 foundation compositions, "long wear" typically means the composition remains on the skin at least about 4 hours up to about 24 hours, and retains rich color.

[00033] "Substituted" as used herein, means comprising at least one substituent. Non-limiting examples of substituents include atoms, such as oxygen atoms and nitrogen atoms, as well as functional groups, such as amine 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, thiosulphategroups, siloxane groups, and polysiloxane groups. The substituent(s) may be further substituted.

[00034] "Stable" or "stable composition" or "stable emulsion" or "stable water-in- oil" emulsion" means that the composition does not change its physical properties (e.g., separation of water and oil phases, creaming, pigment sedimentation) over time and/or under challenging conditions (high or low temperature).

[00035] "Comprising" it is meant that other steps and/or ingredients which do not affect the end result may be added. The products, compositions, methods and processes of the present invention can include all the essential elements and limitations of the invention described herein as well as any of the additional or optional ingredients, components, steps, or limitations described herein.

[00036] As used herein, all ranges provided are meant to include every specific range within, and combination of subranges between, the given ranges. Thus, a range from 1 -5, includes specifically 1 , 2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4, 1 -4, etc.

[00037] Unless otherwise specified herein, all percentages and ratios of components are by weight relative to the total weight of the final composition.

[00038] Hydrophobically treated powders

[00039] According to the present invention, water-in-oil emulsions comprising at least one hydrophobically treated powder are provided. Powders suitable for use in the present invention include, but are not limited to, hydrophobically treated: water-soluble dyes, fat-soluble dyes, inorganic pigments, pearlescent agents, lakes, fillers and their mixtures.

[00040] These coloring materials can be treated at the surface with a hydrophobic agent, such as silanes, silicones, fatty acid soaps, C 9 _ 5 fluoroalcohol phosphates, acrylate/dimethicone copolymers, mixed C9-C15 fluoroalcohol phosphate/silicone copolymers, lecithins or hydrogenated lecithin, carnauba wax, polyethylene, chitosan and optionally acylated amino acids, such as lauroyl lysine, disodium stearoyl glutamate and aluminium acyl glutamate.

[00041] In at least one embodiment, the surface-treated pigments and other powders that are useful in the context of the present disclosure may also be treated with a mixture of these compounds and/or may have undergone several surface treatments.

[00082] Advantageously, the mattifying polymeric powders are sebum- absorbing particles characterized by having a sebum uptake of greater than or equal to 10 ml/100 g, especially greater than or equal to 20 ml/100 g and in particular greater than or equal to 30 ml/100 g, and preferably greater than about 70 ml/100g. The term "sebum-absorbing particle" means a powder that is capable of absorbing and/or adsorbing sebum. Generally, this type of particle is in the form of a powder of particles having a sebum uptake.

[00083] The sebum uptake corresponds to the amount of sebum absorbed and/or adsorbed by the particle. It is measured according to the wet point method described below.

[00084] Advantageously, the sebum-absorbing particle may have a BET (Brunauer-Emmett-Teller) specific surface area of greater than or equal to 200 m 2 /g, preferably greater than 350 m 2 /g and preferentially greater than 500 m 2 /g, and especially less than 2000 m 2 /g.

[00085] The BET specific surface area is determined according to the BET (Brunauer-Emmett-Teller) method described in The Journal of the American Chemical Society, Vol. 60, page 309, February 1938 and corresponding to the international standard ISO 5794/1 (appendix D). The BET specific surface area corresponds to the total specific surface area (thus including micropores) of the particle and especially of the powder.

[00086] The mattifying powders (sebum-absorbing particles) may be an inorganic powders or an organic powders. The particle or particles of one or more inorganic compounds used in the cosmetic composition may have different shapes, for example regular or irregular spheres, full or hollow, glitter, needles or platelets and preferably they are approximately spherical. The useful mattifying agent are described for example in US2015/174044, the disclosures of which is hereby incorporated by reference.

[00087] In certain embodiments, the mineral mattifiers may be chosen from mica, hectorite, calcium aluminum borosilicate, precipitated calcium carbonate, magnesium carbonate, magnesium hydrogen carbonate, hydroxyapatite, hollow silica microspheres, glass or ceramic microcapsules, clay, quartz, natural diamond powder, and mixtures thereof.

Each letter of "MDTQ" denotes a different type of unit. When the film forming resin is made up predominantly of tri-functional units (or T units), it is generally called a silsesquioxane resin, which is described, for example in US 2006/0292096, herein incorporated by reference. Optionally, the units can contain modifications containing long chain carbons such as, for example, C9-C75 carbon chains, C16-C60 carbon chains, C20- C50 carbon chains, C30-C45 carbon chains, etc. The resulting modified resin is sometimes referred to as a "resin wax."

[000210] In an embodiment the invention relates to a method of making the above-described a water-in-oil cosmetic composition which is made according to steps described below.

[000211] 1 . Ingredients of Phase A1 were combined in a main kettle/beaker.

[000212] 2. Then, all compounds of Phase A2 were added in the main kettle and all ingredients were homogenized for 2 hours using a Silverston mixer. In order to maintain the room temperature of the batch, the kettle was placed in an ice bath.

[000213] 3. Next, the compounds of Phase A3 were added and mixed for

additional 5 minutes and then all ingredient of Phase A4 added and grinded for an additional 10-15 minutes. The ice bath was still used to keep the

temperature of the formulation at the room temp.

[000214] 4. In a side kettle/beaker combined ingredients of phase B, mixed them until homogenous and clear mixture was obtained.

[000215] 5. The composition from the main kettle was moved to Rayneri mixer, added with ingredients of Phase A5 and cut with a chopper blade until the mixture was homogeneous.

[000216] 6. Finally, the ingredients of Phase 6 were separately added and mixed until the composition had a homogenous texture. After that Phase A7 was incorporated

[000217] 7. With both phases at room temp added in phase B and continue

mixing for 10-15 minutes using a homogenizing blade.

[000218] 8. Then added phase C and continue mixing until homogenous using the chopper blade for about 5 minutes. In order to maintain the room

temperature of the prepared batch, all steps from 1 -8 were done in an ice bath. [000219] The resulting compositions were smooth and creamy, easy to apply and afforded even application. The compositions provided a nice matte finish, good oil control, evened skin tone and were not ashy on darker skin shades.
