Description

Self-adhesive eyelash system and related methods {MAGNETICALLY ATTACHABLE EYELASH PROSTHETIC SYSTEM AND RELATED METHODS}

The present invention relates to a prosthetic system for magnetically attaching eyelashes to the eyelid/eye contour skin for cosmetic enhancement. Also provided is a method of making and using the disclosed prosthetic system to magnetically and reversibly attach/detach one or more eyelash prosthetic units.

The present technology relates to a prosthetic system for attaching eyelashes with magnets to the eyelid/eye contour skin for cosmetic enhancement. Methods of making and using the disclosed prosthetic system for magnetically and reversibly attaching/detaching one or more eyelash prosthetic units are also provided.

In particular, there is a particular need for cosmetic formulations that can be applied to facial skin. Mascara and eyeliner are especially desirable for consumers. This is because these beauty enhancing products provide real benefits to consumers by enhancing their confidence by having a noticeable effect on the appearance. Mascara can be formulated to coat natural lashes with pigments and eyelash enhancers to cosmetically exaggerate the thickness and length of natural lashes with minimal effort. The female population is "in demand" for more innovative products that can favorably present ordinary lashes to lush, thick and long lashes. Product developers seek to meet consumer expectations by inventing a wide range of "cosmetic eyelashes" or "eyelash prostheses" that can be made from human hair, animal hair, insect-derived fibers and various synthetic mixtures thereof. Since wearing cosmetic eyelashes can greatly improve the size/clarity of the user's eyes, there is an increasing demand for eyelash prostheses worldwide among women of a wide range of age groups. However, the existing eyelash prosthesis may have some discomfort, preventing the majority of women from trying it. In most cases, daily use of eyelash prostheses is cumbersome, time-consuming, requires a steady touch, and is overexposed to potentially toxic adhesive formulations that can promote wrinkles on delicate eyelids.

To avoid the unpleasant user experience associated with sticky adhesive adhesive use, alternative progressive products have been put on the market. Recently, magnetic eyelashes containing small magnets have been developed that can be superimposed on each other as a top/bottom pair, and have been developed to be positioned above and below the original eyelashes for stabilization. These magnetic eyelashes do not have any technical difficulties in applying them, but it requires several attempts to properly attach the lower magnetic eyelashes and the upper upper magnetic eyelashes in order to stably fix them around the original eyelashes.

Demand for less toxic, more convenient to apply/remove, more durable, more comfortable and more advanced and reliable eyelash prosthesis products without sacrificing the beautiful aesthetics of lush, long magnetic eyelashes to enhance cosmetic effects. Is not being met.

The concept of the present invention is a self-adhesive eyelash prosthesis comprising two main components: a load-bearing magnetic eyeliner ("magnetic eyeliner") and a self-adhesive eyelash prosthesis (one or more) including a "magnetic lash base" It's about the system. "These two magnetic products are designed to be magnetically attracted to each other during the intended use of the product, because the magnetic eyeliner contains "magnetic particles" suitable for cosmetics, where "magnetic particles "This is because it can magnetically attract the "self lash base" of the eyelash prosthesis., It supports the stable attachment of the eyelash prosthesis.

In several instances, the present invention relates to a magnetic resistant eyeliner capable of attaching one or more magnetic eyelash prostheses, comprising: (a) a pigment suitable for eyelid cosmetic formulations; (b) one or more magnetic particles suitable for use in colored cosmetic formulations; And (c) a strength structural adhesive capable of being attached to the surface of the eyelid and magnetically supporting the attachment of a magnetic eyelash prosthesis (here, the cosmetic formulation can be converted from a gel state to a strength adhesive state). After coating the skin surface; Since the adhesive force between the load-bearing structural adhesive of the skin-attached eyeliner and the surface of the eyelid is greater than the magnetic force between the load-bearing eyeliner and the eyelash prosthesis, the eyelash prosthesis can be reversibly attached and detached.

[001] In several embodiments, the present invention provides a lash base comprising (a) one or more magnetic elements partially formed of a silicone polymer and exhibiting high magnetic magnetic force; And (b) a plurality of eyelash hairs attached to the lash base at the proximal end-the magnetic elements are positioned on a portion of the lash base and arranged to face the surface of a magnetic eyeliner film that may be formed on the eyelid.

. D. Magnetic eyeliner formulation bearing

Exemplary structural adhesive

In general, an adhesive may be defined as a material capable of holding two or more surfaces together. A wide range of adhesive formulations can be considered and can be distinguished as "pressure sensitive adhesives" (PSA) and "structural adhesives". Adhesive (PSA) can adhere strongly to solid surfaces by applying light contact pressure and short contact time, and is useful for manufacturing "post-it" notes, adhesive pads, pressure sensitive tapes, various labels and a wide variety of products. . Three different types of commercially used PSAs are described as either a) organic solvent based, b) water soluble (emulsion), or c) thermoplastic resin. Although pressure-sensitive adhesives are recognized as easy to apply and remove from the surface, they have relatively lower load-bearing performance than structural adhesives, and, similar to most skin surfaces, are more prone to inadvertent separation from substantially moist/oily surfaces. easy. Alternatively, structural adhesives can be defined as adhesives that "cure" or "cure" with a material capable of stably holding two or more substrates together for the expected life of the product. Structural adhesives are often referred to as "strength" adhesives, and exhibit higher strength-bearing performance than the aforementioned PSA. Structural adhesives can be formulated using a variety of polymer chemistries including polyurethane, acrylic, silicone, vinyl or epoxy based polymers and blends among other suitable materials known to those skilled in the art.

[0011] With regard to skin contact adhesive formulations, a variety of different types of adhesives can be used to enable skin bonding. Suitable examples include various temporary skin adhesives to support wound closure/damage repair. These formulations use in particular a blend of monomers formed from cyano acrylate monomers and 2-octylcyanoacrylate (CAS 133978-15-1) and/or n-butylcyanoacrylate. Other skin formulations may include octyl 2-cyanoacrylate (CAS 6701-17-3), isobutyl 2-cyanoacrylate, and a variety of functionally equivalent substances.

Unfortunately, cyanoacrylate formulations can be limited for use as skin adhesives in that they can be polymerized in the presence of water, adhere well enough to the skin, and polymerize quickly (tens of seconds to minutes). have . These formulations should be stored dry to prevent activation as they can begin to cure upon contact with moist skin. So they need to be applied relatively quickly and spread accurately. Because their adhesion to the skin is quite substantial and can last for a relatively long period (about 1 day to several days), these formulations may not be suitable for formulating eyeliner products in the following respects: a) these The formulation will not be tolerated sufficiently intermittently. Cosmetic application for 4-12 hours, and b) early removal from the skin surface, requires considerable force and can cause considerable discomfort. Since cured formulations are also difficult to remove by traditional detergents that include soap and water, more volatile and potentially dangerous solvents such as ethanol, ethylacetate or acetone will remove the film/layer formed on the skin from these formulations. May be needed. However, this type of solvent is known to degrease the skin and can cause skin irritation. Since the skin of the eyes is very sensitive, it is advisable to avoid the use of these volatile, irritating and potentially hazardous solvents during eyeliner product use/product removal. Therefore, as in the example of the cyanoacrylate-based structural adhesive mentioned above, there is a need to find a more suitable skin attachment formulation that does not easily separate from the skin and does not adhere strongly, such as the PSA described above.

Exemplary Pigment Pigments

The addition of pigments allows the eyeliner product to be formed from a variety of shades to any desired color. Suitable pigments can be selected from natural or synthetic, metallic, non-metallic, inorganic pigments, organic pigments and/or pearlescent pigments depending on the desired visual appearance, flowability, diffusivity, dispersibility and/or wetting ability. Suitable pigments can be provided: a) various particle size ranges, typically from tens of nanometers to about hundreds of micrometers; b) with or without surface treatment; c) hydrated or dehydrated form; And d) being mixed with each other or as is to reach the desired color spectrum. Exemplary inorganic pigments include black, yellow, red and brown iron oxides; Titanium dioxide (rutile or anatase) (white), manganese violet; Ultramarine; These include chromium oxide (green) and ferric blue. Organic pigments include pigments D&C yellow, D&C orange, D&C red, carbon black and other dyes and/or lakes. Pearlescent pigments include white pearlescent pigments such as mica coated with titanium oxide or bismuth oxychloride; It is a colored pearlescent pigment, such as titanium mica with iron oxide, titanium mica with ferric or chromium oxide, titanium mica with organic pigments of the type mentioned above, and pigments based on bismuth oxychloride.

Exemplary magnetic particles and magnetic elements

[0014] To create a magnetically attachable eyelash prosthetic system, (a) suitable "magnetic particles" exhibiting strong ferromagnetic properties for inclusion in a magnetic eyeliner formulation and (b) for inclusion in a "magnetic lash base" These magnetic elements, which are suitable "magnetic elements" that exhibit strong ferromagnetic properties, can be used as follows: (i) filler, (ii) color imparting component, and (iii) fixation of the "magnetic lash base" to the present invention/ It is a magnetic material that facilitates adhesion.

In order to stably attach the magnetic eyelash prosthesis to the magnetic eyeliner, the ferromagnetic properties of the magnetic particles and the magnetic element must be compatible (eyelid skin attachment / pre-coating). As a preferred embodiment, the ferromagnetic material exhibiting high magnetic force is the "magnetic particle" contained in the "bearing magnetic eyeliner" formulation, preferably 10-25,000 kA/m, more preferably 100-15,000 kA/m, most preferably For example, 1,000-10,000 kA / m. As a preferred embodiment, the "magnetic element" having an essentially high magnetic force is a "magnetic lash base", preferably 10-25,000 kA/m, more preferably 100-15,000 kA/m, most preferably "magnetic lash. Is included in the "base" is from 1,000-10,000 kA/m.

[0016] As another embodiment, a material suitable for forming a “magnetic element” for inclusion in a “magnetic lash base” is a powdered/micronized ferromagnetic element, typically used in hard or soft type permanent magnets, Ferromagnetic alloys and ferromagnetic compounds, alloys such as samarium-cobalt alloys including SmCo5, Sm2Co17, such as iron, cobalt, nickel, and optionally alloyed with Fe, Cu and Zr; Neodymium-Iron-Boron Nd2Fe14B optionally alloyed with Pr and Dy, commonly referred to as "rare earth" or "super magnet"; And/or other alloys such as bismanol and alnico.

[0017] As another embodiment, a material suitable for forming "magnetic particles" for inclusion in a "magnetic eyeliner" includes, without limitation, a ferromagnetic compound such as an oxide-based magnetic pigment including an iron oxide such as hematite Fe . 3, Magnetite Fe II (FeIII) 2O4, superparamagnetic iron oxide (SPIO), chromium dioxide CrO2, barium ferrite (BaFe12O) 19, Ba2ZnFe18O23, BaFes2 + 2Fe3 + 16O27), bismuth ferrite (BiFeO3), manganese-zinc ferrite (MnZn) , Cobalt ferrite, CoFe2O4, strontium ferrite, SrFe12O19 or yttrium iron granite (YIG) Y3Fe3. It is 5O 12.

[0018] As another embodiment, "magnetic element" and "magnetic particle" are provided in an encapsulated or non-encapsulated form, and are environmentally friendly, including suspension, dispersibility, surface wetting properties, skin compatibility, and oxidation resistance. Properties such as resistance from factors can be optimized. For example, iron oxide can prevent environmental degradation or direct skin contact by adding a masking agent containing fatty acids such as undecylene, lauric acid or oleic acid.

Regarding the size of "magnetic particles" suitable for use in a magnetic eyeliner formulation, a generally preferred size range cannot be easily distinguished visually with the naked eye, thereby avoiding a granular shape. In several embodiments, the magnetic particles exhibit an average diameter size of 1 to 1 mm, preferably 5 to 500 μm, most preferably 50 to 250 μm. In another embodiment, the magnetic particles exhibit an average diameter size in the range of 100 nm to 1 μm, and the magnetic particles may be further encapsulated to inhibit subcutaneous transport.

Black iron oxide, available in various size ranges and chemistry, is considered particularly useful because it not only imparts a rich black color, but also imparts the desired magnetic properties to the basic formulation. The total composition range suitable for these iron oxide magnetic particles is 10-60 (w/w%), more preferably 20-50 (w/w%), and most preferably 25-45 (w/w%). Can). The higher the coercive force of the "magnetic particles" selected as the pigment component, the smaller the amount needs to be included in order to achieve the desired self-adhesion to stably adhere the "magnetic lash base" to the complementary formulated "magnetic". It should be noted. A similar rationale may apply regarding the inclusion of a “magnetic element in the “magnetic lash base” in the eyeliner. Thus, the magnetic adhesion required will depend on the material selection and the amount of “magnetic particles” added to the “magnetic eyeliner”. It can be finely controlled through the relative amount of "magnetic element" added to the "magnetic lash base".

[0021] The inventors of the present application said that a suitable skin attachment formulation is an acrylate polymer blend, preferably methyl and ethyl acrylate, 2-hydroxy ethylacrylate, butyl acrylate, isobutyl acrylate, t-butyl methacrylate , Isooctyl acrylate, ethyl hexyl acrylate, isobornyl acrylate, vinyl acetate and more particularly: ethyl hexyl acrylate copolymer with a total weight ratio of 0 to 30 (w/w%), more preferably 5 to 25 (5 to 45 (w/w%), more preferably 10/w%) and most preferably 10-15 (w/w) in combination with w butyl acrylate, methyl methacrylate and methacrylic acid copolymer %) -30 (w/w%) and most preferably 15-25 (w/w%), molecular weight range of 5,000-30,000 g/mol, more preferably 10,000-20,000 g/mol and most preferably For example, 15,000-20,000 g / mol. The latter polymer blend may be particularly suitable for forming structural adhesives that can stably adhere to the skin of the eyelids.

Suitable thickener

[0022] Thickening, gelling, thickening, bulking and/or thixotropic agents can be added to facilitate blending with other acylates in liquid, depending on the desired flowability and smearing properties for optimized application to the skin. For example, natural such as carob gum, guar gum, gum arabic, gum karaya, gum tragacanth and gati gum, agar-agar, carrageenan, alginate, gelatin, casephosphate, albumin, pectin, starch, polysaccharides. Gum-based gelled xanthan gum, chitin and/or chitosan, polydextran such as carboxymethyldextran, carboxymethylcellulose, hydroxypropylcellulose, methylcellulose, hydroxyl-propyl methylcellulose or hydroxyethylcellulose Cellulose and cellulose derivatives, and cellulose derivatives modified by alkyl- or alkoxy groups.

Natural resins, fragrances, oils and waxes of plant or animal-derived materials may be added to further improve the performance of the eyeliner.

Suitable film-forming ingredients

In formulating a load-bearing magnetic eyeliner, other desirable properties include cosmetic functions such as film formation and opacity control properties that can facilitate formation of a homogeneous and visually pleasing opaque film surface. The inventors of the present application can improve these properties through the addition of styrene/methacrylate/acrylate copolymer blends including, but not limited to, methacrylic acid-styrene copolymers and/or their respective alkali salts. Was noted. A suitable total weight ratio in the formulation comprising such a styrene/acrylate copolymer blend is 5-45 (w/w%), more preferably 10-30 (w/w%), most preferably 15-25 (w /w %). If more water-resistant film-forming properties are desired, fluorinated acrylate polymers such as 2,2,2-trifluoroethyl methacrylate, 2,2,3,3-tetrafluoropropyl methacrylate, 2,2 ,3,4,4, 4-hexafluorobutyl methacrylate, 2,2,3,3,3-pentafluoropropyl acrylate and/or 1,1,1,3,3,3-hexafluoro Rhoisopropyl acrylate can be added to the surface in a proportion suitable for weather resistance. .

Suitable moisture content

[0025] The total water weight ratio for the provided formulation will be selected from 0-50 (w/w%), more preferably 0-25 (w/w%) and most preferably 5-15 (w/w) I can. w %). When applied, the water evaporates to a residual content (e.g., equivalent to the moisture retained in the skin), substantially solidifying the adhesive formulation in the process, thereby creating a stable structural support and adhesion on the skin substrate.

Desired viscosity range

Viscosity can be adjusted through the desired amount of viscosity agents, thickeners and/or fillers, in particular various pigments. In the basic disclosure, the viscosity of the formulation can typically range from 5 cps-300 cps, which can be measured approximately between the viscosity of water and castor oil (or higher viscosity).

[0027] The polymer blends mentioned above do not cure in the presence of water because they are not provided as monomers and are already cured. They are readily soluble in water and can form viscous gel-like solutions and are suitably provided in a non-crosslinked state. Since the formulation is partially formed from a water-soluble non-crosslinked polymer, the magnetic eyeliner film/layer can be easily removed from the skin by using conventional detergent solutions and skincare products for makeup removal.

Softener / Wetting Agent

[0028] In order to further control the residual moisture content and hardness of the adhesive layer, various humidifying agents, emulsifying agents, softening agents and/or caulking agents may be added to the eyeliner formulation.

F. Exemplary Formulation/Process for Creating Magnetically Attachable Eyelash Prosthesis

[0038] Exemplary formulation / process for producing magnetically attachable eyelash prosthesis: Magnetically attachable eyelash prosthesis includes (a) a lash base including one or more magnetic elements exhibiting high magnetic force, and (b) proximal And a plurality of eyelash hairs attached to the lash base at the ends, the magnetic element being positioned toward the surface of the lash base, which can be attached to and contact with the surface of the magnetic eyeliner film formed over the eyelid. "Magnetic Lash Base", "Magnetic Elements" and "Eyelash Hair" are further described below.

"Magnetic Lash Base" can be made of a wide range of polymeric materials, as long as these materials are substantially flexible and can be formed to conform to the skin, have adequate skin compatibility without significant irritation potential, and can be easily mixed have. Considered magnetic element. Suitable polymers from which the eyelash base can be formed are fluoroelastomers, polysulfones, polyamides, polyurethanes, polyesters, polyethers, silicones, polycarbonates, polyurethane carbonates, polyesters, polyamides, polyimides, polyvinyls and Polyolefins, polyvinyl alcohols, poly acetates, blends and mixtures thereof.

Particularly suitable for skin contact applications may be polyurethane and silicone-based materials due to their inherently low potential for irritation, good skin compatibility and a wide adjustable range of flexibility. These polymeric materials are available with a wide range of elastic properties, which can be expressed, for example, through measurements of Shore hardness A in the range of 0 to about 90 durometers. For a given application, a range of less than 50 durometers, more preferably less than 40 durometers and most preferably less than 30 durometers can be considered as the optimum softness range. In addition, the above-mentioned polymers have good blending properties and can be processed through a wide range of methods that are ideally suited for blending with the "magnetic elements" under consideration.

[0041] The magnetic element is not limited to the exact placement of the polymeric substrate used to form the contemplated "magnetic lash base". For example, magnetic elements can be incorporated, adhered, layered, reacted, blended/mixed, embedded, grafted, bonded, blended, crosslinked, copolymerized and/or reacted with monomers to form a polymeric substrate, or as part. A method of making an intermediate layer that can be adhered, adjoined, adhered and/or reacted or combined with a polymer substrate used to form a “magnetic lash base” in any way. In addition, the magnetic element can be combined with a conventional polymer, and the combination is attached on/around/within the “magnetic lash base” or the surface of the device so that the magnetic element and the polymer substrate are simultaneously or sequentially. Magnetic elements can be incorporated into a polymeric substrate of a "magnetic lash base" through a variety of processes including dispersion, suspension, sedimentation, encapsulation, coating, layering, film deposition, sputtering, spraying and similar functional equivalents. Depending on the specific process applied, the spatial distribution of the magnetic elements dispersed in the "magnetic lash base" can be substantially isotropic, anisotropic, homogeneous or non-uniform, or in the form of a gradient or non-gradient distribution.

[0042] Since the magnetic adhesion between the surface of the first ferromagnetic material (eg, magnetic element) and the surface of the second ferromagnetic material (eg, magnetic particles) depends on the orientation and distance between each other, “magnetic lash The smaller the gap existing between the "magnetic element" contained in the base" and the "magnetic particle" of the "magnetic eyeliner", the stronger the resulting adhesion. Thus, the magnetic element of the "magnetic lash base" is preferably placed locally close to the surface of the eyeliner. In order to achieve this specific spatial arrangement, magnetic particles can be settled by gravity in the monomer solution during the curing process of the polymer substrate used to form the "magnetic lash base". Alternatively, magnetic force can be used to apply an anti-gravity pool to the magnetic element when suspended in a monomer solution so that the particles are preferably oriented at the top of the substrate rather than at the bottom of the substrate.

Exemplary structural configuration formed as a single silicon layer

[0049] In order to create a suitable "magnetic lash base" comprising a magnetic lash base magnetic element, the following process may be applied to form it as a single silicon layer. The silicone RTV or platinum cured compound can be mixed with the desired amount of magnetic elements in a non-polar solvent such as heptane. Vacuum is applied to the silicone solution to remove the solvent and residual trapped gas. The silicone solution may be poured onto a first plate comprising a plurality of "eyelash-based" depressions or molds. The amount of solution is adjusted to reach the desired film thickness. Sufficient time is allowed for the magnetic elements to settle on the bottom of the mold. Alternatively, a second magnetized plate can be placed over the first plate, so that the magnetic element can be anchored to the top of the mold. The silicone compound can be left to be substantially cured as needed. The set silicone film can be removed from the mold. The desired "magnetic lash base" outer contour can be cut using mechanical, pneumatic and/or laser cutting methods. The proximal end of the lash hair can be properly positioned in each “own lash base” contour. The oriented eyelashes are fixed and cured on a pre-formed "magnetic lash base" using a silicone adhesive compound. The resulting "magnetic lash base" can be formed as a single silicon layer with a gradient arrangement of dispersed magnetic elements.

As one specific example, 100.0 g of iron (II, III) oxide micronized powder, <5 μm particle size is 100.0 g of 0.001 M solution of Undeck-10-enoic acid n-heptane. The resulting slurry was stirred at room temperature for 20 minutes, and poured into a 1.0 L volume of Part B (base) of a platinum cured Nusil MED-6600 silicone dispersion. The mixture can be homogeneously blended by applying a vacuum until the n-heptane and residual gas are substantially removed. Subsequently, 1.0 L volume of Part A (accelerator) of a platinum-cured Nusil MED-6600 silicone dispersion can be added to the prepared iron oxide suspension dispersed in the silicone base B. The silicone part A:B mixture can be mixed homogeneously below. Applying a vacuum for about 5-10 minutes or until the residual gas is substantially removed. A homogeneously dispersed 2.02 L silicon iron (II, III) oxide suspension was poured into a 200 cm x 100 cm rectangular mold plate and allowed to cure at 25 °C. For a period of at least 45 minutes, yields a cured silicon layer height of 1 mm and has an iron oxide (II, III) oxide areal density of about 0.005 g/cm2, where through sedimentation means, the particles will be positioned towards the bottom of the mold plate. Can After the desired “magnetic lash base” outer contour is cut from the 1 mm silicone layer above, each lash base is in contact with approximately 100 μL of Nusil MED-1137 RTV (the side opposite the magnetic element). Holds pre-determined eyelashes in place.

As a preferred embodiment, the base silicon layer without the magnetic member has a Shore A hardness of about 25 durometer, which will be higher respectively by the proportion of the magnetic member added. If a lower final shore hardness is required, a silicone oil based diluent, such as Dow Corning 360 Medical Fluid 1000 cSt, or other suitable polydimethylsiloxane oil, can be added to the pre-cure mixture, such as the shore hardness prior to curing. It can be adjusted in the range of -30 durometer.

[0053] Depending on the desired areal density of the magnetic elements distributed in the silicone layer intended to produce the eyelash base, the amount of magnetic elements can be easily adjusted (by providing a larger amount each in the formulation provided above). In the example provided, an initial amount of 200.0 g of iron (II, III) oxide can produce an areal density of about 0.01 g/cm 2, 500.0 g of about 0.025 g/cm 2 and 1000.0 of about 0.05 g/cm 2 g. Larger quantities can be considered when needed for the application.

In another embodiment, the magnetic element of the sixth embodiment may be replaced *?* with the magnetic element named in the first, second, fourth and fifth embodiments. Thus, in the selection and amount of the desired magnetic element added, and at the spatial position within the eyelash base, suitable magnetic properties can be transferred to the eyelash base, thereby having an appropriate load bearing capacity when placed on a load bearing magnetic eyeliner. You can create your own eyelash base.

[0055] The amount and areal density of the magnetic element to be formulated in the eyelash base can be obtained through an actual quantitative experiment. For example, a metered amount of magnetic eyeliner can be spread over a defined surface area on a test substrate that reflects the eyelid surface. The test board is turned over, and the magnetic eyelash base is magnetically attached to the magnetic eyeliner. When the magnetic force between the "magnetic eyelash base" and the "magnetic eyeliner" exceeds the gravity pull of the "eyelash base", and the adhesive force between the eyeliner and the test board exceeds the gravity pull, the base acceptance criterion is reached. Worked on.

An exemplary structural configuration for a magnetic lash base formed as a double silicon layer

In order to create a suitable "magnetic lash base" comprising a magnetic element, the following process can be applied to form it into a double silicon layer. The pre-cured silicone sheet can be placed on the plate. Silicone adhesive formulations containing the desired amount of magnetic elements dispersed in a non-polar solvent such as hexane can be sprayed onto the pre-cured sheet. The top coat can be left to dry as needed. "Magnetic Lash Base" contours can be cut using mechanical, pneumatic and/or laser cutting methods. The proximal end of the lash hair can be positioned appropriately in each "self lash base" contour. The oriented eyelashes are fixed and cured on a pre-formed "magnetic lash base" using a silicone adhesive compound. The resulting "magnetic lash base" can be formed as a double silicon layer configuration comprising an upper silicon layer of dispersed magnetic elements placed over the base silicon layer.
