Liquid cosmetics

Abstract

The compositions and methods of the present disclosure include, for example, a liquid cosmetic composition, such as an eyeliner, that is applied to a surface of a user (e.g., a person), the surface including, for example, an eyelid, the liquid cosmetic comprising a ferromagnetic component that is attracted to and capable of attaching to a magnet, and false eyelashes that are provided with a magnetic portion.

Description

Technical Field

[0001] The present invention relates to liquid cosmetics, and more particularly to compositions and methods related to eye products of cosmetics.

Background Art

[0002] Eyelashes are physical features that are selectively altered to enhance appearance. Products such as mascara can be used to make eyelashes appear thicker, fuller, and more lush. However, some people find that mascara alone is not enough. False eyelashes can be attached to the wearer's eyelid and lash area to enhance natural eyelashes.

[0003] Current false eyelashes have drawbacks. For example, an adhesive that is part of the false eyelashes themselves or another adhesive can be used to attach the false eyelashes. The latter is applied to the area of the eyelid where the false eyelashes are to be adhered and then attached to the eyelid. Such adhesives can sometimes irritate the user, and furthermore, forcibly removing such false eyelashes can sometimes cause discomfort, including pain, to the wearer.

[0004] It would be advantageous to provide a composition and method of use for a cosmetic, such as an eyeliner, that can be applied to the eyelid area and comfortably maintained while being capable of being coupled by a magnetic field to false eyelashes having magnetic elements.

Summary of the Invention

[0005] In one embodiment, an eyeliner composition is provided. The eyeliner composition includes a thickening agent in an amount of about 15 weight (wt)% to about 25 weight% and iron oxide in an amount of about 25 weight% to about 45 weight%, and the composition has a viscosity of about 950 cps to about 1300 cps at about 25°C.

[0006] In another embodiment, a liquid eyeliner composition is provided. The liquid eyeliner composition comprises about 15% to about 25% by weight of styrene / acrylate copolymer and about 25% to about 45% by weight of pulverized iron oxide, and the composition has a viscosity of about 950 cps to about 1300 cps at about 25°C and a pH of about 7.5 to about 8.5.

[0007] Another embodiment provides a method for attaching false eyelashes to a user's eyelid using an eyeliner composition. The eyeliner composition comprises a thickening agent in an amount of approximately 15% to 25% by weight and a ferromagnetic component containing iron oxide in an amount of approximately 25% to 45% by weight, and the composition has a viscosity of approximately 950 cps to 1300 cps and a pH of approximately 7.5 to 8.5 at approximately 25°C. The false eyelashes include a base containing at least one magnetic element and false eyelash lashes extending from the base. The method includes depositing a portion of the eyeliner composition onto the eyelid or the eyelash area of ​​the eyelid, and attaching at least one magnetic element of a false eyelash to the deposited portion of the eyeliner composition via the attraction and adhesion of the magnetic element to the ferromagnetic component of the eyeliner composition. [Brief explanation of the drawing]

[0009] [Figure 1] This is a schematic diagram showing the upper surface of an eye, illustrating one embodiment of the present disclosure. [Modes for carrying out the invention]

[0010] Various embodiments of the present invention will be described below. It should be noted that the specific embodiments described are not intended to be exhaustive, nor are they intended to limit the broader aspects discussed herein. Aspect described in relation to a particular embodiment is not necessarily limited to that embodiment and can be implemented in any other embodiment(s).

[0011] The use of the terms “a,” “an,” and “the” and similar reference terms in contexts describing elements (particularly in the context of the following claims) should be interpreted to cover both singular and plural forms, unless otherwise indicated herein or unless the context clearly contradicts this interpretation. The use of ranges of values ​​in this specification is intended solely as a shorthand notation for referring individually to each individual value that falls within the range, unless otherwise indicated herein, and each individual value is incorporated herein as if it were individually listed herein. All methods described herein may be performed in any appropriate order unless otherwise indicated herein or unless it is clearly inconsistent with the context. Any and all examples or illustrative language (e.g., "etc.") used herein are intended solely to better illustrate the embodiments and, unless otherwise stated, do not limit the scope of the claims. No language herein should be construed as indicating that elements not described in the claims are essential.

[0012] Unless otherwise indicated, all figures used herein and in the claims, representing amounts of components, reaction conditions, etc., should be understood in all cases to be modified by the term "approximately." Therefore, unless otherwise indicated, the numerical parameters described herein and in the appended claims are approximations that may vary depending on the desired properties to be obtained by the embodiments of this disclosure. The term "about" as used herein will be understood by those skilled in the art and may vary to some extent depending on the context in which it is used. In cases where terminology is used that is unclear to a person skilled in the art, considering the context in which it is used, "approximately" may mean a range of plus or minus 10% of a particular term.

[0013] In this specification, “cosmetically acceptable” means that the ingredient expressed by this term is suitable for use in contact with tissue (e.g., skin) in a reasonable benefit-to-risk ratio, without excessive toxicity, incompatibility, instability, irritation, allergic reactions, or other adverse effects.

[0014] Aspects of this disclosure relate to a composition, method of use, and method of manufacturing a multipurpose cosmetic composition, such as a liquid cosmetic composition, such as an eyeliner, which is applied to the surface of a user (e.g., a person). The surface includes, for example, the eyelid and / or eyelash area, and the cosmetic composition includes a ferromagnetic component that can be attracted to and adhere to a magnet, and includes a multipurpose eyeliner that can (1) impart the cosmetic features of a conventional eyeliner (applied to the eyelid and / or eyelash area to improve its appearance), and (2) provide an attachment point for false eyelashes containing a magnetic element. Aspects of the present disclosure also relate to eyelash prostheses that include a magnetic element as part of the prosthesis and can be used to attach false eyelashes to the compositions of the present disclosure, for example, the compositions of the present disclosure in combination with false eyelashes, and methods of use and manufacture.

[0015] The eyelid region includes the outer surface of the eyelid opposite the inner eyelid surface, which is adjacent to and / or in contact with the surface of the eye and its associated solutions (e.g., tears). Furthermore, the eyelid region also includes the surface of the eyelid where the eyelashes grow, or a surface adjacent to that surface, on which false eyelashes can be attached without substantially interfering with the opening and closing of the user's eyelids.

[0016] The false eyelashes include an eyelash prosthesis having a base attached thereto and a plurality of false eyelash element fibers extending therefrom. The base can have a length that extends along the length of the user's eyelid area, for example, the average length of the average user's eyelid area, or can have a short portion, such as an eyelash extension. The false eyelashes can also include one or more magnet elements, for example, as part of the false eyelash base structure or attached to the false eyelash base.

[0017] The compositions and methods of the present disclosure include a ferromagnetic component that can be attracted to a magnet and a cosmetically acceptable vehicle. The cosmetically acceptable vehicle includes cosmetic compositions such as, for example, liquid eyeliner. The magnet to which the ferromagnetic component is attracted can be a magnet element that is part of the false eyelash structure, for example, one or more magnet elements.

[0018] The ferromagnetic component (for example, a cosmetically acceptable ferromagnetic component) can include ferromagnetic materials and compounds such as, for example, iron (such as iron oxides like Fe203 and Fe304), nickel, cobalt, and some rare earths (gadolinium, dysprosium). The ferromagnetic component can include such materials or compounds in the form of particles, but also includes pulverized iron oxide that is in a particle form smaller than the non-pulverized form. The pulverized form can be made, for example, by using a triple-roller mill to pulverize non-pulverized iron oxide powder together with a viscous liquid such as water. The ferromagnetic component containing iron oxide can act as a colorant for the purpose of darkening the eyeliner.

[0019] One embodiment of the present disclosure can include a ferromagnetic component, for example, iron oxide (pulverized or non-pulverized) in an amount ranging from about 25 wt% to about 45 wt% or about 40 wt%, and a cosmetically acceptable vehicle carrying the iron oxide.

[0020] Cosmetically acceptable vehicles can include, for example, aqueous-based vehicles containing viscosity increasing components (e.g., cosmetically acceptable thickening components) such as polymers (e.g., styrene / acrylate copolymers), magnesium aluminum silicate, and gellan gum. The amount of the viscosity increasing component (thickening component) can be present in an amount ranging from about 0.5 wt% to about 2.0 wt% depending on the desired viscosity of the composition. In embodiments of the present disclosure including a styrene / acrylate copolymer used as the thickening component, the styrene / acrylate copolymer can be present in an amount ranging from about 15 wt% to about 25 wt% or about 20 wt%.

[0021] In other embodiments of the present disclosure, various optional components such as skin colorants, dispersants, solubilizers, preservatives, and colorants can be included.

[0022] The skin colorant can change the color of the eyeliner and can include cosmetically acceptable skin colorants. Examples of skin colorants can include, for example, ultramarine (Cl 77007) and manganese violet (Cl 77,742). The skin colorant can be present in an amount ranging from about 30% to about 40% in the case of ultramarine and from about 3% to about 5% in the case of manganese violet.

[0023] The dispersant can include cosmetically acceptable dispersants. Examples of dispersants can include PEG-40 hydrogenated castor oil, polysorbate 20, and sodium stearoyl glutamate. The dispersant can be present in an amount ranging from about 0.5 wt% to about 1 wt%.

[0024] The solubilizer is volatile for accelerating the drying of the product and can include cosmetically acceptable solubilizers. An example of the solubilizer can include denatured alcohol. The solvent can be present in an amount ranging from approximately 1% to approximately 3% by weight.

[0025] The preservatives may include cosmetically acceptable preservatives. Examples of preservatives include phenoxyethanol, ethylhexylglycerin, and caprylyl glycol. The preservative can be present in an amount ranging from approximately 0.5% by weight to approximately 1% by weight.

[0026] One embodiment of this disclosure is shown in Figure 1. Figure 1 includes an eye 100, an eyeball 102, an eyelid 104, and eyelashes 106. The eyelid 104 includes eyelashes 106 connected to the eyelid 104 at eyelash connection points 108 within the area of ​​the eyelid 104. Figure 1 also includes at least one deposit 110 of the liquid cosmetic compositions and embodiments of the present disclosure. The deposit 110 makes several individual or smaller deposits by forming a continuous linear deposit of the same (e.g., from one side of the eyelid to the other), or by magnetically interacting (including one or more coats or applications of the composition) and adhering to magnetic elements thus positioned on the false eyelashes, thereby resulting in the desired positioning of the false eyelashes. Figure 1 also includes a false eyelash 112 having a base 114, a false eyelash element 116 extending from the base 114, and a magnetic element 118 connected to the base 114 (some of which may be one or more magnetic elements separated or incorporated into the base 114). Following the liquid cosmetic composition and the deposit 110 of the embodiments of the present disclosure, the false eyelashes 112 are positioned in contact with the deposit 110 such that the magnetic element 118 adheres to the deposit 110 via the attraction and adhesion of the magnetic element to the ferromagnetic components of the deposited composition.

[0027] The viscosity of the liquid cosmetic composition of this disclosure may be in the range of about 950 cps to about 1300 cps or about 1100 cps when tested at 25°C. For a liquid cosmetic composition to function properly, it needs a viscosity that is not too thick, thus not negatively impacting application (for example, being too thick to be easily applied or to be unable to be removed from the container). Furthermore, the ferromagnetic component (e.g., iron oxide) must not be so diluted that it is substantially uniformly suspended or distributed throughout the entire composition. Such an uneven suspension or distribution of ferromagnetic components results in a composition that, when applied as an eyeliner, may not allow the magnetic elements of false eyelashes to adhere sufficiently magnetically. The pH of the liquid cosmetic compositions of this disclosure may be in the range of about 7.5 to about 8.5. Lower pH levels may adversely affect the viscosity of the liquid cosmetic compositions and embodiments of this disclosure. As a result, the compositions and embodiments of this disclosure have several desirable cosmetic and other qualities for the wearer, including, but not limited to, high comfort, ease of application, and long-lasting wear upon application.

[0028] The liquid cosmetic compositions and embodiments of this disclosure may be deposited onto the eyelid area using one or more coats or applications of the composition, either directly from the container of the liquid cosmetic composition or using an acceptable applicator, such as an application wand. The application wand may include bristles of various sizes, including bristles ranging in size from approximately 1.2 mm to approximately 1.4 mm. Larger bristles can be applied to a wider range of liquid cosmetic compositions and embodiments of the present disclosure, allowing for better reach of the eyelid area with fewer coats or applications. The cosmetic compositions and embodiments of the present disclosure can be achieved by (1) creating a continuous linear deposit of the same (for example, from one side of the eyelid to the other), or (2) creating several individual or smaller deposits as they are appropriate. This can be achieved by appropriately arranging them to interact magnetically (both including one or more coats or applications of the composition, e.g., about 1 to about 4), and by creating deposits of the same that adhere to the magnetic elements thus positioned on the false eyelashes, resulting in the false eyelashes being in the desired position (both including one or more coats or applications of the composition, e.g., about 1 to about 4).

[0029] Embodiments of the present disclosure may also include a composition embodiment of the present disclosure and a combination of the composition embodiment of the present disclosure with an eyelid region and / or eyelash region of the eyelid, wherein the false eyelash containing at least one magnetic element is brought into contact with and attached to the composition via the attraction and adhesion of the magnetic element to the ferromagnetic component of the composition. Methods for obtaining a combination may include depositing the composition onto the eyelid and / or eyelash region of the eyelid, and attaching false eyelashes containing at least one magnetic element to the composition via the attraction and adhesion of the magnetic element to the ferromagnetic component of the composition.
