Composition and method for drying application of mascara

In summary, the present invention relates to cosmetic compositions for eyelashes and methods of applying such cosmetic compositions to eyelashes.

Conventional mascara formulations are typically moisturizing or wettable suspensions in the form of a viscous paste which must be applied to the eyelashes of a person using a brush or comb applicator. Prior art mascara compositions can be characterized as Newtonian or non-Newtonian (to include pseudoplastic and expansive fluids) under ambient conditions, depending on the desired product properties. Such mascara formulations can be cumbersome and difficult to apply when applied. The mascara is loaded onto the brush applicator and then brought into contact with the eyelashes to transfer the mascara to the eyelashes. Generally, in order to achieve the desired effect, the application process or carding is repeated multiple times, which is cumbersome and time consuming, often resulting in accidental deposition of the product in the eye or on the eyelids or facial skin, requiring remedial action. After proper application, the mascara is then dried on the eyelashes. During drying or curing, the composition may and will transfer from the eyelashes if contacted, so other remedies and, in some cases, re-application of the product are required.

This method of application requires hand stabilization and must be done in a static environment to avoid mascara staining other parts of the face or clothing. In addition, applying a mascara near the eye using a brush applicator with bristles may be more difficult and may force people to stop using mascara. People with poor eyesight or poor hand-eye coordination feel very difficult or quit using these products when using mascara products. With conventional mascara products and methods of application, it is not possible or very difficult to impart the desired visual effect to the eyelashes, such as a pattern or design. Therefore, there is a need for an improved mascara formulation and a mascara application that avoids such problems.

The present invention provides a composition and a method of applying a dry or solid mascara formulation to the eyelashes. It is an object of the present invention to provide an improved composition and method of applying a dry mascara formulation to the eyelashes for immediate effects. The present invention provides a simple and effective drying application technique that avoids the disadvantages of conventional mascara application formulations and application techniques. The methods and compositions can apply mascara to the eyelashes in a variety of patterns or designs, which is difficult or impossible to achieve with conventional mascara formulations or methods of application. In addition, the method and composition achieve immediate results.

In another embodiment, a dry mascara formulation is provided that can be deposited on a planar substrate and can be transferred from the substrate to the eyelashes by contacting the formulation with the eyelashes.

In one embodiment, a mascara application system is provided comprising a first substrate material for use as a carrier for the mascara formulation, a dry mascara formulation, and a second substrate material disposed over the mascara formulation .

In yet another embodiment, the mascara application system is provided by a multi-layer system comprising a backing film, one or more adhesive layers, a patterned ink layer, and a transfer film layer, and a plurality of optional layers.

In another embodiment, a method of applying dry mascara to an eyelash is provided, comprising contacting an eyelash with a dry mascara formulation positioned on a carrier substrate and applying pressure or heat to the mascara formulation or substrate as appropriate , light or a combination thereof to transfer mascara to the eyelashes.

The present invention enables mascara having various patterns, designs, or effects to be easily and effectively applied to the eyelashes to achieve the desired eyelash appearance. In addition, the patterns and designs can be superimposed on each other to deliver a stereoscopic effect.

The present invention provides novel compositions and products for applying makeup to eyelashes and methods of applying the compositions to eyelashes. These products comprise a cosmetic (e.g., mascara) for eyelashes that differs from this type of conventional cosmetic in that it is provided in a substantially solid form. The compositions of the present invention can be provided to consumers as a peel and stick type product. The compositions may be in the form of a powder, a solid, a semi-solid, or a combination thereof, but may not be a viscous liquid or a paste-like mascara product.

Yet another difference from conventional products is that the invention can be made by one or more printing methods. That is, the invention can be substantially any scale of printed pattern and/or design. Moreover, the invention may manifest itself as a single point or a group of combined points or be constructed to deliver the desired effect. In this connection, the term "dot" should be used as a general descriptive term, in any case the term "dot" may represent an infinite number of possible shapes. For example, shapes may include, but are not limited to, a ring, a triangle, a star, a square, a rectangle, a rhombohedron, a pentagon, a hexagon, an octagon, and the like, which are composed of at least two points. Printing methods include, but are not limited to, lithography, offset printing, xerography or laser printing, release coating printing, digital printing, inkjet printing, and rotogravure or silk Web printing. The compositions of the present invention can be considered to be immediacy, i.e., operations or drying times that do not require the desired effect.

The compositions and methods of the present invention can be carried out, for example, in the following manner. Referring now to Figure 7, an embodiment of the product of the present invention can be described as a simple layer system 1. The cosmetic product of the present invention may be composed of a backing film 11 or a protective layer on which an adhesive layer 12 is placed. The next layer should be a colorant or printed image (patterned ink layer 122) that is completely incorporated or embedded in the above-described adhesive layer 12 and the last layer should be a transfer film 14 material made of a suitable material, such as paper, plastic, or combination. In this configuration, the backing layer acts as a disposable substrate to protect the adhesive 121 from contamination or premature drying prior to use. Adhesive 121 is used to adhere the colorant or printed image (patterned ink layer 122) to the eyelashes and to adhere the cosmetic composition to backing film 11 and transfer film 14 prior to use. The transfer film 14 contains the cosmetic composition and functions as an applicator to apply the composition to the eyelashes. The transfer film 14 is then peeled off after the composition is in place and the adhesion mechanism is triggered. The cosmetic composition can be applied to the adhesive/backing material by any suitable means, such as printing or the like, and can be provided as a uniform coating or can be patterned thereon.

Generally, the backing film 11 serves as a shield for the adhesive 121. It contains a material having a certain affinity for the adhesive 121 so that the adhesive is adhered to the backing film 11 but the backing film 11 can be easily removed. The transfer film 14 or sheet serves as a fixture for the side or a portion of one of the cosmetic compositions prior to use. Additionally, the adhesive 121 is used to adhere the cosmetic composition (when in use) to the eyelashes and is typically a pressure sensitive adhesive that provides sufficient directness to maintain the cosmetic composition on the eyelashes for a period of time desired by the consumer. .

The product usually also contains a thin plastic or paper material (preferably a transparent plastic such as transparent polyethylene or Mylar). A backing film 11 that covers and protects the cosmetic composition prior to use. The backing film 11 should be removable by peeling without substantially damaging the composition. The cover layer can be held in place by an adhesive on the periphery or corners of the backing layer or by any other suitable means.

Referring now to Figure 8, an embodiment of the product of the present invention can be described in more detail as a more complex multi-layer system. The carrier layer 21 or the protective non-stick layer is in direct contact with one or more of the adhesive layers 3. This carrier layer 21 may be, for example, a biaxially oriented polyethylene terephthalate polyester film (Mylar) ) and other materials. The contact layer 31 directly contacting the adhesive layer 3 may be the sealing layer 31 to protect the colorant or printed pattern layer 32. A patterned ink layer 32 or a colorant layer is interposed between the surface preparation layer 35 containing polyvinyl alcohol, polyvinylpyrrolidone, gelatin or a combination thereof and the second sealing layer 33. The sealing layers 31 and 33 may be varnishes composed of a drying oil, a resin, and a solvent. The next layer is a release coating 34 comprised of a non-adhesive polyoxyl or polyoxymethylene mixture which separates the composition from the backing layer or second carrier 22. An optional sizing agent 37 can be employed to improve the stiffness or structure of the backing layer or second carrier 22 comprised of paper, plastic, or a combination thereof. The two carriers 21, 22 are designed to be peelable, the first carrier 21 is protective and when exposed, the adhesive that secures the composition to the eyelashes can be exposed. The second carrier 22 functions as an applicator and is peeled off after the composition is fixed to the target substrate (in this case, the eyelashes).

To apply the composition to the eyelashes, the user first removes the protective layer (if present) from the product to expose the cosmetic composition. The backing layer is then folded over the eyelashes so that the composition deposits on the tip and/or root of the eyelashes, as depicted in FIG. The backing layer can provide perforations or creases generally in the middle of the sheet to facilitate folding. The composition is transferred from the backing layer to the eyelashes in contact therewith, preferably by applying pressure, for example, by pressing the folded backing layer with a finger or with specialized equipment adapted to receive the folded product. Optionally, the backing layer, application tool or composition itself may contain an indicator to alert the user when a suitable condition for adequate deposition is achieved. The indicator can express itself by visual or tactile mode. The transfer can be improved by the application of heat, which is expected to reduce the force required to remove the composition from the backing layer and transfer the composition to the eyelashes. The product may be preheated using a hair dryer or the like or it may be adapted to heat the backing material during application. The backing material is then removed from the eyelashes by relieving the applied pressure. Optionally, the product or eyelashes can be moistened to aid in removal.

The invention described herein avoids the disadvantages of conventional mascara formulations and application techniques by applying a dry mascara formulation to the eyelashes using a novel dry transfer application method. The dry mascara application methods described herein do not include applying a moist or wet mascara formulation by brushing the eyelashes using a conventional brush applicator. In addition, the present invention can contribute to a variety of aesthetic effects (patterns, designs, etc.) that are difficult or impossible to achieve for conventional mascara.

The adhesive may also be incorporated into or part of the cosmetic composition or sprayed onto the composition and incorporated into or form part of the composition.

Referring now to Figure 1, an embodiment of the product of the present invention depicts the eyelashes being superimposed on a lower portion thereof. The shape of the backing layer is substantially unlimited, but preferably at least one of the edges has a concave curvature that substantially matches the curvature of the eyelid to achieve maximum coverage when the product is placed against the eyelashes, as depicted in FIG. The opposite edges of the product can also be similarly constructed so that when the product is folded to wrap the eyelashes, the tip and root of the eyelashes are maximally covered.

The backing layer can be comprised of any suitable material that can be folded without breaking, including, but not limited to, polypropylene, acetate, polystyrene, or paper. In a presently preferred embodiment, the backing layer is a transparent, flexible material.

The backing layer can be coated or laminated with an adhesive layer to improve the adhesion of the cosmetic composition thereto. Any adhesive suitable for cosmetic or medical use can be used.

The adhesive may be applied uniformly to one of the surfaces of the backing layer or may be printed or patterned on the backing layer such that when the cosmetic product is deposited on the backing layer, it is primarily adhered to the adhesive and thus reflects the adhesion Printing pattern of the agent. In this way, various aesthetic effects can be achieved.

The key component of the product of the invention is a cosmetic composition that is provided on the backing layer in a substantially dry form.

In a presently preferred embodiment, the cosmetic composition comprises Acronal V 215 (BASF), which is an aqueous dispersion of an acrylate-based polymer, an ink comprising a phenolic resin and a cellulose derivative dissolved in Dowanol and/or An ink composed of a pigment/dye in an acrylic acid solution, a vinyl/cellulose derivative dissolved in water, and optionally a carbon black as a colorant.

The cosmetic composition can be applied to the backing layer by any suitable means, including the methods commonly used in the preparation of cosmetic "samplers". For example, bulk film application techniques such as extrusion or jetting techniques have been used to make cosmetic samples, as set forth in U.S. Patent No. 6,691,872, the disclosure of which is incorporated herein by reference. These techniques distribute the cosmetic composition evenly over the surface of the backing layer. Additionally, the invention may be made by industrial printers (including but not limited to Redd Europe, Main Titles and LetraSet), or by medical adhesives and tape manufacturers (eg, especially Mactac, Scapa Group Plc, Adhesives Research Ltd. and Tape Specialties). ) Manufactured by an industrial printing method.

In other embodiments, the cosmetic composition is printed onto the backing layer. The method of printing a cosmetic onto a substrate is also well known, as disclosed in, for example, U.S. Patent No. 5,192,386, the disclosure of which is incorporated herein by reference. The printing process deposits the cosmetic composition onto the substrate in precise amounts and patterns. Furthermore, the product can be printed in two or more different colors by means of a printing method to provide a unique effect when applied to the eyelashes.

Additionally, the patterns can be mixed and matched to one another or in any of the above shapes, lines, or other configurations contained therein. Such combinations can be administered in separate administration events (i.e., on opposite sides of the same piece) or in separate events of two or more sequential administrations. For example, the first application should be deposited as a circle on the eyelashes and then applied again to be deposited as a complete line, dashed line, or a different shape or set of shapes than the first application.

Referring to Figure 1, a non-limiting example of the types of effects that can be achieved is illustrated. In a preferred embodiment, the product may comprise a uniform coating of colored mascara so that when applied to the eyelashes, the colored mascara is transferred to the eyelashes in a relatively coherent manner to produce an appearance comparable to conventional mascara products. The mascara composition can be applied to the upper side of the eyelashes, the underside of the eyelashes, or both.

Figures 1 and 14 also illustrate certain graphical effects A that can be achieved by, for example, printing two or more colors onto a backing layer. In many variations of this embodiment, mention may in particular be made of those in which a color gradient is applied to the backing layer to form a color gradient on the eyelashes as the cosmetic composition is transferred to the eyelashes. A color gradient B can be applied along the long axis of the backing layer (ie, along line II) to form a color gradient from each lash root to the lash tip, or across the backing layer from left to right (ie, perpendicular to line II) A color gradient B' is formed to establish a color gradient across the eyelashes from left to right. In addition to the color gradient, similar effects can be achieved using two or more colors in discrete bands such that, for example, the portion of the eyelash closest to the root is one color and the portion closest to the tip is a different color or the like. There are basically no restrictions on the achievable aesthetic effects, including (but not limited to) (only a few examples) rainbow patterns, wave patterns, and sunrise patterns.

As shown in Figures 1 and 14, the backing layer can further comprise a plurality of self-adhesive micro-dots C, which can be used alone or in combination with a cosmetic composition. The microdots C may themselves comprise a dry cosmetic composition or may be made from a polymeric material or the like, and will typically include an adhesive to facilitate transfer to the eyelashes. The tiny points C can be constructed in any pattern that can be uniform in size or vary in size and shape and located in any spatial orientation necessary to achieve a particular or desired effect. The tiny dots C can form a complete straight line, a dashed line, any of the above larger shapes, or any design that can be printed by one or more of the above listed printing techniques. Also, the backing layer may further comprise a cosmetic composition (L) arranged in a line L along I-I.

Referring to Figure 9, a non-limiting example presents the invention as a series of tiny points. The microscopic dots can be of any size but typically (but not necessarily) have a diameter of from about 10 [mu]m (microns) to about 2 mm, more typically from about 50 [mu]m to about 1 mm, or from about 500 [mu]m to about 0.5 mm. A plurality of tiny dots may be the same color or may be in different colors. It has been found that when the dry mascara product is in the form of tiny dots (especially when the tiny dots have a suitable size that can be supported on more than one eyelash), a dense effect can be obtained.

Figure 1 also illustrates the use of a clear composition to impart a matrix of eyelashes M that secure and separate their lashes. The transparent composition can comprise a transparent adhesive polymer, for example, which is printed on the backing layer in a pattern (e.g., a plurality of columns). When the composition is transferred to the eyelashes, the rows of clear compositions are arranged substantially perpendicular to the eyelashes to form a matrix. Alternatively, the clear composition can be applied to the backing layer as a uniform film. In this manner, the entire length of the eyelashes, or a portion thereof, is encapsulated in a polymeric film. The film can be sized such that it extends slightly beyond the tip of the lash to provide a continuous "hard" edge or the size of the film can be determined so that the lash tip extends beyond the edge to provide an edge with a "feathery" appearance. In addition, the present invention may take the form of a straight line or the like as illustrated in FIG. 3 to extend the lash tip to impart an eyelash extension effect.

In another principal embodiment, there is provided a method of applying a dry mascara D formulation to an eyelash comprising contacting the eyelash with a dry mascara D formulation deposited on a carrier substrate, and optionally changing the mascara Temperature or apply pressure, light, or a combination thereof to the eyelashes and mascara formulation to adhere the mascara formulation to the eyelashes. In one embodiment, pressure is applied to the mascara formulation and the substrate. In another embodiment, the mascara formulation and the substrate are applied with heat when they are in contact with the eyelashes. In another embodiment, the dry mascara D formulation is exposed to light when in contact with the eyelashes. In an alternate embodiment, the mascara is adhered to the eyelashes by maintaining the formulation in contact with the eyelashes for a period of time (without applying pressure, heat or light). The carrier substrate is not a conventional brush applicator for applying mascara. In one embodiment, the carrier substrate is a film material. In one embodiment, an application tool is used to transfer the dry mascara D formulation to the eyelashes. The application tool incorporates the dry mascara D formulation on one or both of the surfaces in contact with the eyelashes. 1 and 2 illustrate examples of application tools that incorporate a dry mascara D formulation on a surface that is placed in contact with the eyelashes.

The method of applying mascara can apply mascara to the eyelashes in various patterns, designs or effects to achieve the desired eyelash appearance. With the present invention, a desired pattern or effect can be selectively applied to the upper surface of the eyelashes or the underside of the eyelashes. In one embodiment, a mascara having a desired colorant pattern is applied to the eyelashes. Figure 4 illustrates several color patterns or gradients that may be achieved using the present invention. In another embodiment, a mascara having a small graphic or graphic is applied to the eyelashes. In another embodiment, a mascara having a refractive substance, such as a scintillator, is applied to the eyelashes. Figure 6 depicts an eyelash with a mascara containing a scintillator. As a non-limiting example, the mascara product of the present invention may be matte, semi-matte, glossy, semi-glossy, and combinations thereof. In another embodiment, a mascara having a desired visual effect (eg, a rigid "hard eyelash" effect) or having a "black extinction point" pattern is applied to the eyelashes. 5A-C show eyelashes with a "hard eyelash" effect; FIG. 5A shows an eyelash with a "natural" effect; FIG. 5B shows an eyelash with a "dull black stripe" effect; and FIG. 5C shows an "dull black dot" effect Eyelashes. Figure 6 depicts an eyelash with a "black extinction point" pattern. In another embodiment, a mascara having various elements (eg, "extinction black dots") can be applied to the eyelashes. The method can easily control the amount of mascara to be applied to the eyelashes by controlling the amount of dry mascara deposited on the carrier substrate. The present invention is capable of imparting sharpness, length, visual effects (including holographic effects), and abundance or a combination thereof. Alternatively, eyelashes having a sparse or thick mascara coating can be easily achieved using the present invention.

FIG. 10 illustrates an embodiment of the present invention in which a plurality of cosmetic micro dots C (pattern C' of tiny dots) and an adhesive 422 are disposed on the backing layer of the transfer sheet 4, wherein the adhesive 422 and the transfer sheet 4 are formed strong. Combine. The backing sheet 41 covers the product and is removed to expose the adhesive 422 and cosmetic minute points C. When the exposed adhesive 422 is pressed onto the eyelashes E, it adheres to the eyelashes E and transfers the minute dots C from the transfer sheet 4 backing layer to the eyelashes E. These minute points C are only weakly bonded to the transfer sheet 4 and thus can be easily transferred to the eyelashes E together with the adhesive 422.

In an interesting embodiment, the product may have a pressure sensitive ink I on the surface of the transfer layer opposite the cosmetic, as illustrated in Figures 11A-C. Figure 11A shows a perspective view of this embodiment in which the symbol G is a cosmetic (e.g., a tiny dot). Figure 11B shows a top view of this embodiment. When sufficient pressure has been applied to transfer the cosmetic to the eyelashes, the pressure sensitive ink I changes color and thus serves as an indicator that the product has been successfully uniformly applied (as shown in Figure 11C). In another embodiment, the product may use tactile cues, such as a protrusion that changes the transfer layer to alert the consumer when the applied pressure is sufficient to transfer the cosmetic to the eyelashes. 11D-F show the application method of this embodiment: as shown in FIG. 11D, the first step is to punch the package, and the second step is to remove the dry mascara carrier; as shown in FIG. 11E, the third step is to Placed on the eyelashes, and the fourth step is to squeeze the parts to apply the product, as shown in Figure 11F, the fifth step is to remove the carrier, and the sixth step is to repeat the second step for the lower eyelid and the other eye. To the sixth step.

It has been found that certain patterns of printed cosmetics are excellent for obtaining uniform coverage and excellent transfer of the cosmetic to the eyelashes. As shown in Fig. 12, the transfer efficiency is relatively low for the line-shaped cosmetics (printing along the line I-I) because the eyelashes cannot be aligned with the cosmetic lines at equal intervals. The slanted hexagonal pattern of hexagonal points is expected to have excellent adhesion to the eyelashes. However, the invention is not limited to any particular pattern of printed cosmetics.

An exemplary applicator device of the present invention is illustrated in Figures 13A-B. In Fig. 13A, the folded product 5 is fitted into a recess 71 formed between two rigid plate-like members 7, which may have a micro-arched configuration depending on the contour of the eyelid. In operation, the user applies a force to the handle 73 that brings the panels together to provide the pressure necessary to transfer the cosmetic to the eyelashes. It is contemplated that any of the handle actuation mechanisms can be adapted to generate sufficient pressure to transfer the cosmetic to the eyelashes. In Figure 13B, the product 5 is held in the internal recess 81 of the stick device 8. The groove 81 is formed between the terminal end 83 of the device 8 and the edge of the solid member 85 slidably disposed within the device 8, so that the slidable member 85 can be moved toward the device 8 by the pressure of a thumb or the like. The terminal 83 thus engages the product 5 and creates sufficient pressure to transfer the cosmetic to the eyelashes. However, it should be understood that a special applicator device is not required, and the product can be simply used by the pressing force between the index finger and the thumb. The application methods of the embodiments of Figures 13A-B can be summarized as follows: 1. Loading the filler (which can be stored in the handle); 2. Place the applicator and aiming at the eye; 3. Move the thumb upwards (grip/squeeze) ) to apply pressure uniformly and release; 4. remove the applicator; and 5. repeat steps 1-4 for the other eyelash and the other eye.
