Multi-functional surface solid support

Field of the invention
The present invention concerns a multi-functional surface solid support supporting two or more dry topically acceptable compositions, notably for providing a cosmetic care.
More particularly, the present invention relates to the field of cosmetic compositions which are applied onto a solid support to deliver a targeted cosmetic care at different zones to a subject in need thereof.

Background of the invention
Cosmetic compositions are combined with substrates or supports such as nonwovens, paper or polymeric film to enhance their functionality as well to provide new sensorial experience to consumers or users. Wipes, facial mask and pads are typical examples of such combination products. In general, the substrate or support is impregnated by one cosmetic composition and packaged for sale. The functionality of these products mainly depends broadly on the functionality of the cosmetic composition and more directly on the active ingredients used in the cosmetic composition for example: cleansing, makeup removal or refreshing is targeted in wipes, while for facial mask moisturisation, whitening or antiageing is generally targeted.
The skin care required for the face varies from region to region of a subject, the care needed for these different regions are different. For example: T-zone of the skin tends to be oilier than U zone of the skin, therefore skin care composition needed for two zones of the face are different with each other. Similarly, another example can be the zone around the eyes and the remaining zone of the face which each needs different skin treatments. According to this sense, the terms “region” and “zone” are equivalent.
Therefore, there is need for developing a method or process, wherein a specific care benefits two or more particular skin zones. More particularly, as the lipo-protein structure of the face varies from region to region, the nourishment needed for different regions of face are different based on the type of remuneration required. Therefore there is need for developing a method or process wherein different regions of the face can be treated simultaneously with a particular skincare composition for providing a specific skin care or benefit for that particular skin region or zone.
The application of different topical compositions on required skin zones is quite apparent but it is not convenient for the consumer to handle several distinct cosmetic compositions. Applying different cosmetic composition in appropriate quantity at different zones could also represent a difficulty. Therefore there is need of a single product which is composed of multi-cosmetic compositions.
Though the process of imbibing multi-cosmetic compositions is already taught in the prior art; there still remains the problem of restricting the interaction of multiple cosmetic compositions between each other. In fact, different zones of the face which need different cosmetic cares are located close together (undereyes, cheeks, etc) and may present a common front line. Therefore, multi-cosmetic compositions should be put close together on a single support but avoid mixing between the different cosmetic compositions.
US patent 2006/0104931 discloses cosmetic treatment articles comprising at least two different gel compositions, each gel composition being provided at one or more selected locations on a water insoluble substrate. Although the gel composition reduces the chances of mixing the two compositions, the risk cannot be completely eliminated in the packaging and even during use or application.
US patent 2010/0191314 A1 describes a temperature controlled face mask with specific areas to provide different cares, but does not address the problem of eliminating the mixing of these compositions in packaging as well as during use.
PCT application WO 2011/146321 provides a system and a method for individually delivering multiple skin benefit agents to skin of a user. The method uses imaging device and digital printer but still does not address the problem of the mixing of these agents with each other.
The present invention aims to provide a solution to the above mentioned problems. The invention aims to provide a single product comprising of more than one formulation which can be packed and used while avoiding mixing of the formulations. More particularly, the invention aims to provide a more convenient way for the consumer or user to apply several distinct cosmetic compositions, preferably in appropriate quantity, at different regions of user’s skin. The invention also aims to limit the delivery of active ingredients to unwanted/undesired zone(s) of a keratinic material of a subject in case of application of multiple cosmetic compositions in multiple zones by way of a single product or device. The invention also aims to limit the potential reduction of the activity of active ingredients in case of application of multiple cosmetic compositions in multiple zones by way of a single product or device. More generally, the invention aims to overcome the problems linked to interaction of multiple cosmetic compositions in case of application of multiple cosmetic compositions in multiple zones by way of a single product or device.

Summary of the invention
The invention relates more specifically to a multi-functional surface solid support (1) supporting two or more dry topically acceptable compositions, wherein said solid support presents at least one functional surface defining n+1 functional areas (10, 20, 30), wherein n is an integer equal or greater than 1, wherein each functional area (10, 20, 30) comprises a topically acceptable composition (11, 21, 31), wherein at least two or more topically acceptable compositions comprise each independently at least one water soluble polymer and at least one topically acceptable ingredient.
These compositions may be applied onto distinct areas of a solid support but in close spatial connection, even including a common front line, without mixing or overlapping of the compositions during packaging or use.
This invention relates to a support where one or more topical compositions are deposited on different areas of said support and then dried in order to facilitate the application of these formulations without mixing and dripping of formulations, said area targeting a specific zone of a keratinic material of a subject in need of a topic care. The support is advantageously hydrated or wetted before application in order to re-hydrate the topical compositions and facilitate their effect to each zone of said keratinic material.

Detailed description of the invention
Each composition comprises at least one water soluble polymer and at least one active ingredient. In the sense of the present invention “an active ingredient” has to be interpreted very broadly as it will be benefic to a keratinic material. More particularly, the invention relates to active ingredients exerting a topic care. In general, said active ingredient is transferred from the support to the keratinic material.
In one embodiment, said n+1 functional areas cover partially or essentially completely one surface said solid support.
According to a specific embodiment n is 1.
According to a specific embodiment n is 2.
According to a specific embodiment n is 3.
According to a specific embodiment n is 4.
According to a specific embodiment n is not greater than 5.
When n is greater than or equal to 2, said support may comprise either distinct or same or some distinct and some same cosmetic compositions. For example, one embodiment is a solid support comprising 3 functional areas and 2 distinct compositions. Another embodiment is a solid support comprising 3 functional areas and 3 distinct compositions. In the former case, adjacent functional areas do not comprise the same composition.
Typically, the keratinic material is represented by the tegument, including skin, hairs, etc. In one embodiment, said keratinic material is the skin. In one specific embodiment, the keratinic material is skin of the face.
In one embodiment, the topically acceptable composition is a cosmetic composition.
The present invention is applicable to all topically acceptable supports in general. As used herein, the term “topically acceptable supports” refers to devices or supports which are adapted for application to a keratinic material, especially to skin. Such supports are adapted to an application on the body of a human subject in need of a topical care. More specifically topically acceptable supports are supports or devices for personal care, including wipes, facial masks and the like. This invention is described in context of facial mask but can be readily adapted to other topically acceptable supports as well.
As used herein term “facial mask” refers to solid support comprising a substrate sheet in the shape of face and generally comprising designed areas for eyes, nose and mouth. Such areas are generally cut in the substrate sheet.
Such solid support may be of more complex shape for fitting the face. A facial mask may also cover hears. A facial mask may also cover the hairs, partially or completely. A facial mask may also cover the neck, partially or completely.
According to one embodiment, the solid support comprises one substrate sheet.
According to one embodiment, the solid support comprises two or more substrate sheets each independently made of, or comprising, identical or different substrates.
According to one specific embodiment, a multi-functional surface solid support is an applicator body as defined in Indian patent application filed on July 25, 2013 under number 2215/DEL/2013. Solid supports are for example selected among face masks, wipes and pads. For instance, a face mask is a solid support which is cut in to the shape face with slits for eyes, nose and mouth and supports a cosmetic product depending on targeted functionality.
The functionality of such a solid support mainly depends on the activities of the active ingredients. Moisturisation, whitening and anti-aging are the most common functionalities for such a solid support, especially face mask.
The most common format of a solid support of the invention may be for example folded and packed in a single use sachet. In some cases, solid supports of the invention are distributed in the format of a roll pack. Such a roll pack comprises a substrate roll with a plurality of multi-functional solid supports of a predetermined shape, for example a plurality of face masks. A cosmetic product can be applied on such a solid support of the invention after its detaching from the roll pack.
In a particular embodiment, the multi-functional surface solid support is a face mask. In this case, an outer contour of the mask defines an essentially oval or circular shape. Alternatively, it defines a polygonal shape. For such a face mask, the surface area of the essentially oval or circular shape is comprised between 0.25 cm2 and 500 cm2, preferably between 200 cm2 and 450 cm2.
Advantageously, the multi-functional surface solid support comprises inner cavities. Such inner cavities comprises two through openings intended to be placed facing the eyes of the user, and another through opening intended to be placed facing the mouth of the user.
In one embodiment, the mask also comprises a slit delimiting a flapper intended to be pushed away by the nose of the user, to delimit a nose insertion through opening.
In a variant, the essentially oval or circular shape of the face mask is completed with shapes facing the neck and/or ear hangings of the user.
In another variant, the multi-functional surface solid support is formed into a patch or a garment having a volume, for example a sock, glove or sleeve.

Substrate sheet
The multi-functional solid support is made of, or comprises, one or more substrates. Such substrate may be for example a substrate sheet or layer.
Advantageously, the solid support is water insoluble. By “water insoluble”, it is meant that the solid support does not dissolve or readily break apart upon immersion in water.
Advantageously, the solid support comprises at least a fibrous layer. It comprises for example woven fibers, knitted fibers, non-woven fibers or/and a polymeric mesh.
Advantageously, the substrate sheet comprises fibrous layer of non-woven fibers. In a preferred embodiment, the substrate is a non-woven material.
By “non-woven”, it is meant, in the sense of this invention, a substrate including fibers in which the individual fibers or filaments are arranged in a disordered manner in a sheet-like structure and which are neither woven nor knit. The fibers of the nonwoven substrate are generally linked to one another, under the effect of a mechanical action (for example, by needle-punching, air jet, water jet, etc.), or under the effect of a thermal action, or by adding a binder. Such a non-woven material is, for example, defined by standard ISO 9092, as a web or a sheet of fibers oriented directionally or at random, bound by friction and/or cohesion and/or adhesion, excluding paper or products obtained by weaving, knitting, tufting or stitching incorporating threads or bonding filaments. A non-woven material differs from a paper by the length of the fibers used. In paper, the fibers are shorter. However, there are nonwoven materials based on cellulose fibers that are produced by wet process and have short fibers as in paper. The difference between a nonwoven material and a paper is generally the absence of a hydrogen bond between the fibers in a nonwoven material. The fibers can be natural fibers, synthetic fibers or mixtures thereof. Non limiting examples of synthetic fibers are Polyester, Polyolefin (Polypropylene, Polyethylene), Polyamide (Nylon 6, Nylon 66), Viscose, Acrylic fibers, Modacrylic fibers, Poly vinylidene chloride and Spandex. Examples of natural fibers include cellulosic fibers (such as wood pulp, cotton, hemp, jute, and flax fibers), silk, and keratin (such as wool and camel hair fibers).
The solid support typically has a density of 30 g/m2 to 400 g/m2, preferably 40 g/m2 to 80 g/m2.
According to one embodiment, the solid support is designed to present a multi-functional surface for topical application on a keratinic material and a surface opposite to said multi-functional surface.
In a preferred embodiment, the solid support may comprise a liquid impermeable film on a surface or substrate opposite to said multi-functional surface. More particularly, at least one liquid impermeable film is applied (for example laminated) on a non-woven substrate opposite to said multi-functional surface and the topically acceptable compositions are applied onto said multi-functional surface of said non-woven substrate. Advantageously, the occlusive film avoids or at least limits transfer of topically acceptable compositions from one side to another side of said support and also facilitates long lasting application of such support by keeping the support in wet conditions for longer duration during the application.
The most common example of liquid impermeable film is polyethylene and polypropylene films. These films prevent or at least minimize the transfer of topically acceptable compositions from one side to another. Non-limiting example of such films are Polyethylene, Polypropylene and PET (Polyethyleneterephtalate) films.
According to another embodiment wherein the support needs to be applied on the keratinic material for certain period of time breathable liquid impermeable film can be used. As used herein, the term “breathable” means that the film or barrier is permeable to water vapor and gasses. In other words “breathable films” allow water vapor and gasses to pass through but not necessarily other liquids.
Non limiting examples of such breathable-liquid impermeable are the films composed of sufficient amounts of polymers such as poly vinyl alcohol (PVOH), polyvinyl acetate (PVA), ethylene vinyl alcohol (EVA), polyurethane, ethylene methyl acrylate (EMA) and ethylene methyl acrylic acid (EMM) to make them breathable.
These liquid impermeable films can be applied (for example laminated) on a substrate, especially a nonwoven substrate, according to various ways. The merely examples of various bonding but not limited to, are thermal bonding adhesive bonding and sonic bonding.

Topically acceptable compositions:
Topically acceptable compositions to be used in the frame of the invention comprise at least one water soluble polymer and at least one topically acceptable ingredient. “Topically acceptable” means compatible with the tegument, preferably the human tegument, and especially human skin. The terms « topically acceptable composition » refer preferably to a composition presenting acceptable color, odor and feeling by topical application and does not generally generate inacceptable discomforts susceptible to discourage a user from using said composition.
The water soluble polymer makes advantageously a dry film upon drying on the targeted area of said solid support and prevents from the mixing of these compositions in dry condition in packaging and in wet conditions during the application.
Advantageously, a water soluble polymer is selected among water soluble polymers. More preferably this is a filmogenic polymer. A filmogenic polymer is adapted to form alone or with other filmogenic agents, a continuous film, preferably adhering to a keratinic material, and preferably to skin.
By “water soluble polymer” is meant that said solid support made of at least this polymer, upon immersion in water at 25°C disintegrate and/or dissolve slowly e.g. over period of several minutes to one day without stirring.
The solid support retains its shape and does not disintegrate and/or dissolve during the application time on the keratinic material.
The water soluble filmogenic polymer is preferably selected from the group consisting of starch, pullulan, starch, cellulose, derivatives thereof, and blend thereof.
Advantageously, a water soluble polymer used in this invention is selected from the group consisting of cellulose and derivatives thereof. A good water soluble polymer for use in the present invention is cellulose ethers, notably water-soluble methylcellulose and especially hydroxypropyl methylcellulose (HPMC) polymers, for example such as those available for example under trade names METHOCEL K35, METHOCEL A15LV, METHOCEL Premium E5 LV and K35 LV from Dow chemical co.
The amount of water soluble polymers in the topically acceptable compositions depends on the viscosity and/or water solubility of the polymer in aqueous solution. Generally it ranges from 0.5 to 20%; more preferably from 1 to 10%; even more preferably from 1 to 5% by mass of the total wet composition mass.
In one embodiment, topically acceptable ingredients of said compositions include at least one skin care agent and/or at least one cosmetically active ingredient.
Cosmetically active ingredients may be for example selected from the group consisting of oils, humectants, surfactants, structuring agents, sunscreens, film formers, preservatives, acidifying and/or alkalizing agents, buffering agents, chelating agents, coloring additives, dermatologically active agents, whitening active ingredients, others skin care agents, cosmetically active ingredients, and any combination thereof.
The term oil refers to a hydrophobic liquid compound at ambient temperature. Suitable oils include silicones, esters, vegetable oils, synthetic oils, including but not limited to those set forth herein. The oils may be volatile or non-volatile, and are preferably in the form of a pourable liquid at room temperature. The term "volatile" means that the oil has a measurable vapor pressure or a vapor pressure of at least about 2 mm of mercury at 20° C. The term "non-volatile" means that the oil has a vapor pressure of less than about 2 mm of mercury at 20° C. Structuring agents will increase the viscosity of, hence structure, the composition. Desirable structuring agents include silicone elastomers, silicone gums or waxes, natural or synthetic waxes, polyamides, silicone polyamides and the like. Sunscreens include chemical UVA or UVB sunscreens or physical sunscreens in the particulate form. Film formers will generally enhance the film formed by the cosmetic applied to the skin and, in some cases, promote water resistance or transfer resistance. Dermatological agents include agents for caring a keratinic material, in particular the skin and more specifically agents for treating inflammation, acne, psoriasis, cutaneous aging, itching, skin color disorders, such as freckles or vitiligo and skin irritation.
For example, the skin care agent and/or cosmetically active ingredient is selected from the group consisting of whitening agents, anti-oxidants, cleansing agents, free radical scavengers, moisturizers, skin tone altering agents, anti-acne agents, anti-aging agents, anti-wrinkle agents, anti-inflammatory agents, skin texture treatment agents, anti-perspirant agents, aesthetics, anti-bacterial agents, nourishing agents, sebum and/or moisture absorbers and any combination thereof.
In one specific embodiment, skin care agent and/or cosmetically active ingredient enables absorption of some skin oil. The composition of said topically acceptable compositions may contain other topically acceptable ingredients such as cosmetically active ingredients which may be for example advantageous in addition to oil absorption.
The topically acceptable compositions can be aqueous or non-aqueous or an emulsion system. This would depend on the solubility and compatibility of the skin care agent(s) used in the compositions.
Non-limiting examples of skin whitening or brightening agents include, but not limited to, skin tone changing pigments, reflective particulate material, soft focus agents and mixtures thereof. The skin tone changing pigments includes but not limited to talc, mica, silica, titanium oxide, zinc oxide and titanium oxide coated mica, borosilicates; hydrophobically modified zinc oxides; hydrophobically modified titanium di-oxides.
Example of anti-oxidants and or anti-inflammatory and/or cooling actives and/or sweat absorption actives to be used in the invention include, but not limited to, Vitamin C, Vitamin E, Derivatives of Vitamin C and Vitamin D, Lycopene, Carrotene, Lecithin, Rice bran lipids, Rice bran oils, menthol; yoghurt, silicated menthols, menthyl lactates; almond oil; peanut oil; sunflower oil; horse gram powder; olive oil; fumated or non-fumated silica, hydrophobically modified silica, hydrophylically silica and mixtures/composites thereof.
The amount of a skin care active agent or a cosmetically active agent may range from 0.001 to 99%; more preferably 0.01 to 30%; even more preferably from 0.01-5% by mass of the total wet composition mass.
In one embodiment, the topically acceptable compositions may additionally comprise one or more other physiologically acceptable ingredients.
Yet in another embodiment of the invention, said topically acceptable compositions comprise one or more plasticizers. Such plasticizer may advantageously increase flexibility and strength of said solid support and in some cases also may provide skin conditioning benefits. Non-limiting examples of suitable plasticizers are glycerin, glycols such as ethylene glycol, propylene glycol, butylene glycol and diethylene glycols, dextrins, sorbitols.
Topical compositions may be for example selected from the group consisting of solutions, notably aqueous solutions or oily solutions, creams, aqueous gels, oily gels, emulsions, microemulsions, nanoemulsions, for example oil-in-water or water-in-oil or multiple or silicone-containing emulsions; and anhydrous products, for example liquid, pasty or solid anhydrous products, without particular limitation. The invention covers any other type of topical compositions, as soon as it may be dried and re-hydrated.
According to one embodiment, different functional areas present a common front line.
According to one embodiment, said support is a face mask.
According to one embodiment, one or more of topically acceptable ingredients present in said topically acceptable compositions are providing a cosmetic care or benefit.
According to one embodiment, said solid support comprises at least a fibrous layer.
According to one embodiment, said solid support comprises on one side a liquid impermeable film.
According to one embodiment, said liquid impermeable film is placed on said solid support on a surface opposite to said multi-functional surface of said solid support.
According to one embodiment, said each functional area (10, 20, 30) is designed to support a cosmetic composition (11, 21, 31) and deliver a cosmetic care to a targeted zone of a keratinic material in need of said cosmetic care.
In one embodiment, one or two functional areas are designed to deliver a cosmetic care to the under eye(s) zone.
In one embodiment, one or two functional areas are designed to deliver a cosmetic care to the cheek(s) zone.
In one embodiment, at least one functional area is designed to deliver a cosmetic care at least partially to one or more remaining zones of the face in addition to at least the under eye zone(s) or the cheek zone(s).

Process for preparing said solid support:
The invention also relates to a method for preparing a multi-functional surface solid support according to the present invention, said method comprising:
(i) preparing a solid support, wherein said solid support presents at least one functional surface defining n+1 functional areas (10, 20, 30), wherein n is an integer equal or greater than 1,
(ii) applying and drying at least one topical composition on each functional area of said solid support to get a solid support supporting two or more dry cosmetic compositions.
The formulation described above can be applied on substrate sheet using printing technology such as screen printing technology and/or digital printing technology.
As used herein the term “screen printing technology” refers to printing technique that uses screen placed on at least one multi-functional surface solid support according to the invention. The screen comprises areas stopping the transfer of the composition to the solid support and areas allowing the transfer of the composition to the multi-functional surface solid support. Areas allowing the transfer of the composition to the multi-functional surface solid support present essentially the same design as functional areas of said solid support. Therefore, by applying the compositions onto the screen, each composition applied may be transferred only to the desired functional area(s) of said solid support. One, some, or all compositions may be transferred to one, some, or all functional areas. Also one, some, or all compositions may be transferred to two or more functional areas. In one embodiment, one or more screens may be used to apply the compositions, each screen allowing the transfer to desired functional area(s).
According to a particular embodiment, one composition is transferred to one or more specific functional areas.
The terms “transfer” and “apply” refer to any mode of application of the composition to/on the screen/multi-functional surface solid support. Any way to support onto said solid support (which also means in this sense “to include into”) said topical composition is appropriate. For example, topical compositions are embedded into or deposited (including spreading) onto said solid support. One specific embodiment relates to topical compositions embedded into at least one substrate of said solid support. This term should be interpreted broadly without any particular limitation on the way the composition is supported onto/by/in the support.
In screen printing technology, a screen represents, according to one embodiment, the inverse or negative image of the design to be reproduced on the multi-functional surface solid support.
In one embodiment, a single screen is used. In another embodiment several screens are used.
In one embodiment, a single screen is used for applying two or more compositions. In such a case, separators can be used to separate different areas of the screen. In one embodiment, each composition is applied in a separate area of the separated screen.
In one embodiment, one screen is used for applying more than one compositions or each composition. In such a case, the design of a screen corresponds to the design of a functional area of the multi-functional surface solid support.
In one embodiment the screen is a mesh. Such a mesh may be stretched out over a frame. The mesh size allows to transfer or apply the desired amount of composition to the substrate or multi-functional surface solid support. As used herein the term “mesh size” refers to the number of threads/cm in the mesh. Lower mesh size of mesh facilitates the more amount of composition transferred to the multi-functional surface solid support. The mesh size may for example range from 12 to 400; more preferably 12 to 200, and even more preferably 40 to 150 threads/cm. In one embodiment, the screen is made up of polyester.

Compositions may be applied on part or total surface of the screen or only in areas allowing transfer of the composition to the multi-functional surface solid support. Areas allowing transfer of the composition to the multi-functional surface solid support are typically represented by one or more through openings or holes in the screen. Such area may be prepared for example by cutting the desired shape into the screen.
In one embodiment, the transfer is performed by an operator manually using means for transferring one or more compositions to the multi-functional surface solid support, for example by using one or more squeezers. In one embodiment, an automatic system is used to transfer one or more compositions to the multi-functional surface solid support. In case of using a mesh or fabric as screen, a composition may be transferred by capillary action in a controlled and prescribed amount defined by thickness of screen and mesh size.
In one embodiment pressure is applied on the screen to transfer the one or more compositions to the multi-functional surface solid support.
In one embodiment, the substrate, and preferably the multi-functional surface solid support, is placed in or on a frame. A screen, for example a mesh, is stretched out preferably over the frame and the frame and screen are deposited on the substrate or multi-functional surface solid support. One or more screens are sequentially applied on the substrate. The compositions are sequentially deposited in areas of screen allowing transfer of the composition to the multi-functional surface solid support or on part or total surface of the screen to transfer the compositions to the desired areas of the substrate or multi-functional surface solid support. The compositions are then transferred to the substrate or multi-functional surface solid support. Such transfer may be performed by example by exerting a pressure on the composition to penetrate the surface of the solid support. The screen and frame are removed from the substrate or multi-functional surface solid support leaving the compositions on the substrate or multi-functional surface solid support according to the prescribed design.
In one embodiment of the invention, ink-jet printing technology is used to transfer the compositions on the multi-functional surface solid support.
Ink printing can be performed for example by propelling droplets of compositions of the invention on the multi-functional surface solid support. In this technique the composition is directly applied on the multi-functional surface solid support without transferring the composition by using other application means, such as screen or mesh. The technology requires generally computer controlled ink-jet printing equipment to deliver different compositions on the multi-functional surface solid support in a certain pattern. This may be referred to also as digital printing.
In another embodiment of the coating technology or press roller technology can be used. These techniques are well known in the state of the art.
In one embodiment, drying of the topical compositions is performed after applying or transferring all topical compositions to the multi-functional surface solid support. In one embodiment, drying is made sequentially after applying or transferring one or more topical compositions to the multi-functional surface solid support. In one embodiment, drying is performed after applying or transferring each composition.
Drying may be performed manually, semi-automatically or by an automatic process. The drying temperature depends upon thermal properties of the multi-functional surface solid support and compositions. Drying enables eliminating water from the compositions, partly or completely. Generally the temperature of the drying step may vary from 35°C to 100°C, more preferably 35°C to 70°C and even more preferably from 40°C to 60°C.
In a specific embodiment, the method comprises:
(i) preparing a solid support;
(ii) applying or transferring a first topical composition on at least one first functional area of said multi-functional surface solid support;
(iii) drying the multi-functional surface solid support supporting the first topical composition;
(iv) applying or transferring a second topical composition on at least one second functional area of said multi-functional surface solid support and optionally applying or transferring a third topical compositions on at least one third functional area of said multi-functional surface solid support;
(v) drying the multi-functional surface solid support supporting the first, second and optional third topical compositions;
(vi) recovering a multi-functional surface solid support supporting the first, second and optional third topical compositions; and
(vii) optionally shaping said multi-functional surface solid support into a body mask, for example a face mask.
According to a specific embodiment, applying or transferring a topical composition on at least one functional area of said multi-functional surface solid support comprises putting a screen, for example a mesh or fabric into contact with a substrate or multi-functional surface solid support, applying said topical composition in areas of screen allowing transfer of the composition to the multi-functional surface solid support or on part or total surface of the screen to transfer the composition to the desired areas of the substrate or multi-functional surface solid support, and transferring said topical composition to said substrate or multi-functional surface solid support.
In one embodiment, the topical composition is transferred to a substrate, which is then used for preparing a multi-functional surface solid support.
In one embodiment, the topical composition is transferred directly to a multi-functional surface solid support.

1. A topical composition for under eye areas comprising cosmetically active ingredients reducing the dryness and intensity of black circles under eyes.
2. A topical composition for cheek areas comprising an anti-acne cosmetic ingredient.
3. A topical composition for the remaining area of the face comprising skin whitening cosmetic ingredients.
The substrate used here was spun on lace nonwoven substrate composed of 96 % cellulosic fibers and 4% Polyester (PET- polyethylene terephthalate) fibers (PET) laminated with 5 microns Polyethylene film (PE) on the surface opposite to the surface on which compositions are to be supported. The three compositions are as follows in table 1:

The viscosity of the compositions was about 2300 cps measured by Brookfield DV 3 ULTRA using RV spindle no. 3 at 25°C , 20 RPM for 1 minute.
To make it user perceivable each composition has a different color. These three compositions were applied on the substrate using the screen printing technology.
The process of applying remaining face area composition on the substrate is illustrated in Figure 2.
Two aluminum frames of 12 x 12 inches (100, 700) were prepared. A screen 550 which was a 100 meshes (polyester) fabric was stretched over a frame 100. The screen 550 comprises areas allowing transfer of the composition to the multi-functional surface solid support 300 : here the screen 550 has through openings in the shape of a face 200.
The frame 100 comprising the screen 550 is deposited on the multi-functional surface solid support 300. Such a multi-functional surface solid support 300 is a substrate sheet in this example. Manual pressure is applied on the squeezer; the squeezer is positioned at around 45° from horizontal. The screen presents a mesh size of about 100 threads/cm.
Composition 130 was deposited, more preferably in open areas of screen 550, and applied on the surface of said multi-functional surface solid support 300 using a squeezer 400.
This resulted in a face shape 30 delimited by an essentially circular front line 12 according to figure 3, wherein a substrate 300 comprises a face image printed on the substrate 300 and designed by composition 130. Composition 300 is located on the face image except under eyes areas 10 and cheek areas 20.
The substrate 300 printed with pink color of composition 130 was than dried at 45°C for 30 minutes.
A screen 520 which was a 100 meshes fabric was stretched over the frame 700. As illustrated by figure 4, a divider 800 is placed in the middle of the aluminum frame 700 to separate two parts of the screen 520. On one side of the divider 800 are located openings for under eyes areas 10 and on other side are openings for cheek areas 20. The aluminum frame 700 comprising screen 520 and divider 800 is placed on the substrate 300. The screen 520 was placed over the substrate 300, which has been already printed with composition 130 and dried, matching the openings of said screen substantially exactly on the respective positions of under eyes areas 10 and cheek areas 20 on the substrate 300. Yellow color composition 110 for under eyes 10 and blue color composition 120 for cheeks 20 was applied on the substrate 300 using the squeezer 600. This resulted in a face shape delimited by an essentially circular front line 12 printed on substrate 300 according to figure 5. Said face printed on substrate 300 comprises composition 110 printed on under eyes areas 10, composition 120 printed on cheek areas 20, and composition 130 printed on remaining of face area 30 delimited by front line 12. Such substrate 300 was again dried for 30 minutes at 45°C.
This substrate 300 was shaped, with an essentially round face mask 1 design along line 5 which may match front line 12. Through openings for eyes 15, nose 35 and mouth 25 were also shaped in order to get mask 1 as shown in figure 1. Substrate 300 was shaped here by cutting means.

Material Area density (gm/m2)
Only substrate 50
Mask with three compositions 60
Composition deposition (dry) 10

The dry composition density of such mask was in the range of 5 to 70 gm/m2.
The dry composition of each mask will depend on size and dimensions of the mask; for example we developed mask 21cm. diameter which contains total 0.40 grams of dry composition.
For application on the user face; the face mask can be wetted or hydrated by dipping it into water or by spraying water on it. On application of water on dry compositions, it forms a gel kind of structures which remain at their respective positions on the multi-functional surface solid support 300. It was observed that water quantity needed for wetting the face mask for providing good adhesion to skin was around 0.80 grams in this specific example.
The wetted mask can be applied on the face for delivering the individual benefits under the eye areas, on cheek areas and remaining face area.
Due to occlusive properties of the multi-functional surface solid support, the face mask produced can be retained in wet conditions on the skin for at least 4 hours. The application time of the face mask needs to be decided according to user sensory comfort and efficacy of the product.
Accordingly, the present invention provides a single product composed of more than one formulation which can be packed and used while avoiding mixing of the formulations. The invention provides a convenient way for a user to apply several distinct topical compositions, preferably in appropriate quantity, at different regions of user’s skin. The invention also limits the delivery of active ingredients to unwanted/undesired zone(s) of a keratinic material of a subject in case of application of multiple topical compositions in multiple zones by way of a single product or device. The invention also limits the potential reduction of the activity of active ingredients in case of application of multiple topical compositions in multiple zones by way of a single product or device, because there is no mixing between the different topical compositions. More generally, the invention limits even avoids interaction of multiple topical compositions in case of application of multiple topical compositions in multiple zones by way of a single product or device.
