Description

Multi-functional surface solid support {MULTI-FUNCTIONAL SURFACE SOLID SUPPORT}

The present invention is particularly directed to a multi-functional surface solid support for supporting two or more topically acceptable dry compositions.

More particularly, the present invention relates to the field of cosmetic compositions applied on a solid support to deliver targeted cosmetic care in different zones of an individual in need of cosmetic care.

The cosmetic composition not only enhances its functionality but also is combined with a substrate or support such as a nonwoven, paper or polymer film to provide a new sensory experience to the consumer or the user. Wipes, facial masks, and pads are typical examples of this combination product. In general, the substrate or substrate is impregnated with a single cosmetic composition and packaged for sale. The functionality of these products varies widely depending mainly on the functionality of the cosmetic composition, for example, more directly depending on the active ingredients used in the cosmetic composition: for example, cleansing, makeup removal or refreshing, Are targeted in the wipe, while in the case of facial mask moisturizing, whitening or antiaging is generally targeted.

The skin care required for the face varies from one area of the subject to another, and the care required for these different areas is different. For example: T-zones of the skin tend to be more oily than the U zones of the skin, and thus the skin care compositions required for the two zones of the face are different. Similarly, another example could be a zone around the eye, each of the remaining zones of the face requiring different skin treatments. In accordance with this aspect, the terms "zone" and "zone" are equivalent.

Thus, it is desired to develop a method or process in which special care is beneficial to two or more specific skin zones. More particularly, because the lipid-protein structure of the face varies from region to region, the nutrients needed for different regions of the face are different depending on the type of remuneration needed. Thus, it is desired to develop a method or process in which different areas of the face can be treated simultaneously with a particular skin care composition to provide a particular skin area or zone with a particular skin care or benefit.

It is fairly straightforward to apply different topical compositions to the required skin zone, but it is not convenient for the consumer to handle several distinct cosmetic compositions. It may also be difficult to apply the different cosmetic compositions in the proper amounts to different zones. Therefore, a single product composed of a plurality of cosmetic compositions is desired.

Although a process for imbibing a number of cosmetic compositions has already been taught in the prior art; There is still a problem of limiting the interaction of a number of cosmetic compositions with each other. In fact, different zones that require different cosmetic care in the face can be located close together (under the eyes, cheeks, etc.) and present a common front line. Thus, a number of cosmetic compositions should be placed close together on a single support, but mixing between different cosmetic compositions should be avoided.

U.S. Patent 2006/0104931 discloses a cosmetic treatment article comprising two or more different gel compositions, each gel composition being provided at one or more selected locations on a water-insoluble substrate. While the gel composition reduces the chance of mixing the two compositions, the risk of mixing during packaging and even during use or application can not be completely eliminated.

U.S. Pat. No. 2010/0191314 A1 describes a thermally controlled face mask for providing different care to specific areas, but does not address the problem of removing packaging as well as mixing of these compositions during use.

PCT Application WO 2011/146321 provides a system and method for individually delivering multiple skin benefit agents to a user's skin. The method uses imaging devices and digital printers, but still fails to solve the problem of mixing these agents together.

The present invention aims at providing a solution to the above-mentioned problems. It is an object of the present invention to provide a single product comprising two or more formulations that can be packaged and used while avoiding mixing of formulations. More particularly, the present invention aims to provide a more convenient way for consumers or users to apply some distinct cosmetic compositions, preferably in appropriate amounts, to different areas of the user's skin. The present invention also provides a method of inhibiting the delivery of an active ingredient to an undesired / undesired zone (s) of a keratinous material of an individual when multiple cosmetic compositions are applied by a single product or device in a plurality of zones . The present invention also aims to limit the potential reduction of the activity of the active ingredient when multiple cosmetic compositions are applied by a single product or device in multiple zones. More generally, the present invention is also directed to overcoming the problems associated with the interaction of multiple cosmetic compositions when multiple cosmetic compositions are applied by a single product or device in multiple zones.

The present invention more particularly relates to a multifunctional surface solid support (1) for supporting two or more topically acceptable dry compositions, said solid support comprising n + 1 functional zones (10, 20, 30) Wherein each of said functional areas (10,20, 30) comprises a topically acceptable composition (11, 21, 31), wherein at least two functional areas The topically acceptable compositions each comprise, independently, one or more water soluble polymers and one or more topically acceptable ingredients.

These compositions can be applied on different areas of the solid support but without speckling or overlapping of the composition during packaging or use, but where they are spatially closely connected, even including a common front line.

The present invention relates to a support wherein one or more topical compositions are deposited in different areas of the support and then dried to facilitate application of these formulations without mixing and dripping of the formulation, Target specific zones of the required keratinous material. The support is advantageously hydrated or wetted prior to application to rehydrate the topical composition and promote the effect of the composition on each zone of the keratinous material.

Figure 1 shows schematically a multifunctional surface solid support in the form of a face mask containing different functional areas (under eyes, cheeks and remaining face parts).
Figures 2 and 3 are photographs taken to illustrate a method of making a multifunctional surface solid support of the present invention in the form of a face mask by a screen printing technique.
Figures 4 and 5 show an intermediate arrangement thereof during the manufacture of a multi-functional surface solid support in the form of a face mask.

Each composition comprises at least one water-soluble polymer and at least one active ingredient. In the context of the present invention, "active ingredient" should be interpreted very broadly since it will benefit keratinous materials. More particularly, the present invention relates to active ingredients that exert topical care. Generally, the active ingredient is transferred from the support to the keratinous material.

In one embodiment, the n + 1 functional areas partially or essentially completely cover one surface of the surface support.

According to a particular embodiment, n is 1.

According to a particular embodiment, n is 2.

According to a particular embodiment, n is 3.

According to a particular embodiment, n is 4.

According to a particular embodiment, n is 5 or less.

When n is greater than or equal to 2, the support may comprise separate or identical cosmetic compositions, or some distinct but some identical cosmetic compositions. For example, one embodiment is a solid support comprising three functional domains and two distinct compositions. Another embodiment is a solid support comprising three functional domains and three distinct compositions. In the former case, adjacent functional regions do not contain the same composition.

Typically, the keratinous material is represented by an envelope, including skin, hair, and the like. In one embodiment, the keratinous material is skin. In one particular embodiment, the keratinous material is a facial skin.

In one embodiment, the topically acceptable composition is a cosmetic composition.

The present invention is generally applicable to all locally acceptable supports. As used herein, the term "topically acceptable support" refers to a keratinous material, particularly a device or support adapted to be applied to the skin. Such a support is applied to the human body of an individual requiring local care. More specifically, the locally acceptable support is a support or device for personal care, including wipes, facial masks, and the like. While the present invention is described in the context of facial masks, it can be readily adapted as any other topically acceptable support.

As used herein, the term "facial mask" refers to a solid support comprising a face sheet of substrate in the form of a face, generally including areas designed to fit the eye, nose, and mouth. Such regions are generally cut into base sheets.

These solid supports can have more complex shapes to fit on the face. The facial mask may also cover the hear. The facial mask may also partially or completely cover the hair. The facial mask may also partially or completely cover the neck.

According to one embodiment, the solid support comprises a substrate sheet.

According to one embodiment, the solid support comprises two or more substrate sheets made of, or comprising, each independently the same or different substrates.

According to one particular embodiment, the multifunctional surface solid support is an applicator body as defined in the Indian patent application filed on July 25, 2013 under the number 2215 / DEL / 2013. The solid support is selected, for example, from a face mask, a wipe and a pad. For example, a face mask is a solid support that is cut into a face shape with slits to fit the eyes, nose, and mouth and that supports the cosmetic product according to the targeted functionality.

The functionality of such a solid support depends primarily on the activity of the active ingredient. Moisturizing, whitening and anti-aging are the most common functionalities for these solid supports, especially face masks.

This most common format of the solid support of the present invention can be folded and packed, for example, into a disposable sachet. In some cases, the solid supports of the present invention are distributed in a roll pack format. Such a roll pack comprises a plurality of multifunctional solid supports of a predetermined shape, for example a base roll with a plurality of face masks. The cosmetic product can be applied on such a solid support of the present invention after its desorption from the roll pack.

In certain embodiments, the multi-functional surface solid support is a face mask. In this case, the outer contour of the mask defines an essentially oval or circular shape. Alternatively, it defines a polygonal shape. In such a face mask, the surface area of the essentially oval or circular shape is 0.25 cm ² to 500 cm ² , preferably 200 cm ² to 450 cm ² .

Advantageously, the multifunctional surface solid support comprises an inner cavity. These inner holes include two through apertures adapted to be positioned in alignment with the user's eye, and another through aperture is adapted to fit into the user's mouth.

In one embodiment, the mask also includes a slit that delimits a flapper that is adapted to be pushed by the user's nose to define a range of nose penetration openings.

In a variant, the essentially elliptical or circular shape of the face mask is completed in such a way as to fit the neck and / or hanging of the user.

In yet another variation, the multifunctional surface solid support is formed of a patch or garment having a volume, such as a sock, glove or sleeve.

Substrate sheet

Multifunctional solid supports are made of or comprise one or more substrates. Such a 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 is not dissolved or easily decomposed when immersed in water.

Advantageously, the solid support comprises at least one fibrous layer. This includes, for example, woven fibers, knitted fibers, nonwoven fibers and / or polymeric meshes.

Advantageously, the substrate sheet comprises a fibrous layer of nonwoven fibers. In a preferred embodiment, the substrate is a nonwoven material.

By "nonwoven" is meant, in the context of the present invention, a substrate comprising fibers, wherein the individual fibers or filaments are arranged in a disorderly manner in a sheet-like structure and are neither woven nor knitted. Nonwoven fabric-based fibers are generally connected to each other under the influence of mechanical action (e.g., by needle-punching, air jet, water jet, etc.), under the influence of thermal action, or by the addition of a binder. Such nonwoven materials may be obtained, for example, by the standard ISO 9092, excluding the paper or product obtained by weaving, knitting, tufting or stitching which incorporates threads or binds filaments Web or sheet of fibers orientated or randomly oriented, bonded by friction and / or cohesion and / or adhesion. Nonwoven materials differ from paper by the length of the fibers used. In paper, the fibers are shorter. However, there is a nonwoven material based on cellulose fibers which is produced by a wet process and has short fibers as in paper. The difference between nonwoven materials and paper is that in general nonwoven materials do not have hydrogen bonds between the fibers. The fibers may be natural fibers, synthetic fibers or mixtures thereof. Non-limiting examples of synthetic fibers include polyesters, polyolefins (polypropylene, polyethylene), polyamides (nylon 6, nylon 66), viscose, acrylic fibers, modacrylic fibers, polyvinylidene chloride and spandex . Examples of natural fibers include cellulosic fibers (e.g., wood pulp, cotton, hemp, jute and flax fibers), silk and keratin (e.g., wool and camel fiber).

The solid support typically has a density of from 30 g / m ² to 400 g / m ² , preferably from 40 g / m ² to 80 g / m ² .

According to one embodiment, the solid support is designed to present a multifunctional surface for topical application on the keratinous material, and an opposite surface of the multifunctional surface.

In a preferred embodiment, the solid support may comprise a liquid impermeable film on the surface or a substrate opposite the multi-functional surface. More particularly, one or more liquid impermeable films are applied (e.g., laminated) onto the nonwoven substrate opposite the multifunctional surface, and a topically acceptable composition is applied on the multifunctional surface of the nonwoven substrate. Advantageously, the occlusive film prevents or locally inhibits the transfer of the topically acceptable composition from one side of the support to another and maintains the support in wet conditions for a longer period of time during application. It also promotes long-lasting application of the support.

The most common examples of liquid impermeable films are polyethylene and polypropylene films. These films prevent or at least minimize locally acceptable composition from being transferred from one side to another side. Non-limiting examples of such films include polyethylene, polypropylene, and PET (polyethylene terephthalate) films.

According to another embodiment in which the support needs to be applied on the keratinous material for a predetermined period of time, a breathable liquid impermeable film may be used. As used herein, the term "breathable" means that the film or barrier is permeable to water vapor or gas. That is, "breathable films" may but need not pass water vapor and gas through other liquids.

Non-limiting examples of such breathable-liquid impermeable materials include polyvinyl alcohol (PVOH), polyvinyl acetate (PVA), ethylene vinyl alcohol (EVA), polyurethane, ethylene methyl acrylate (EMA) A film formed by using a polymer such as ethylene methyl acrylate (EMM) in a sufficient amount, and the like.

These liquid impermeable films can be applied (e.g., laminated) onto a substrate, especially a nonwoven substrate, in various ways. Examples of a small number of various bonds include, but are not limited to, thermal bonding, adhesive bonding, and sonic bonding.

Locally Acceptable  Composition:

Example

Example  Face masks supporting one to three different compositions:

One. A topical composition for an under-eye area, comprising a cosmetically active ingredient which reduces the intensity of the dark circles and the drying under the eyes.

2. A topical composition for the cheek area comprising an anti-acne cosmetic ingredient.

3. A topical composition for the remainder of the face, comprising a skin whitening cosmetic component.

The substrate used herein is made of 4% polyester (PET-polyethylene terephthalate) fiber (PET) laminated with 96% cellulose fibers and a 5 micron polyethylene film (PE) on the opposite surface to the surface on which the composition is supported. And spun onto a lace nonwoven substrate. The three compositions are as follows in Table 1:

Composition 1 Composition 2 Composition 3 Under eye area Cheek area Remaining face area Ingredient list % Ingredient list % Ingredient list % water 91.575 water 89.8983 water 92.047 HPMC 2 HPMC 1.5 HPMC 2 Methyl paraben 0.2 glycerin One glycerin 2 Caffeine 0.5 Methyl paraben 0.1 Methyl paraben 0.2 Sodium heuluranate 0.02 Salicylic acid 2 TiO ₂ One Niacinamide 3 TEA 2.5 Ascorbyl glucoside 2 Ascorbyl glucoside 2 Niacinamide 3 TEA 0.7 TEA 0.7 Yellow 5 0.0015 Citric acid 0.05 Yellow 5 0.005 Blue 1 0.0002 Red 0.003 Total solids content 8.425 10.1017 7.953

The viscosity of the composition was about 2300 cps as measured by Brookfield DV 3 ULTRA using RV spindle number 3 for 1 min at 25 캜, 20 RPM.

For the user to be aware, each composition has a different color. These three compositions were applied on a substrate using a screen printing technique.

The process of applying the composition for the remaining facial region onto the substrate is illustrated in Fig.

Two aluminum frames (100, 700) of 12 inches x 12 inches were produced. The screen 550, which is a 100 mesh (polyester) fabric, was stretched over the frame 100. The screen 550 includes an area capable of delivering the composition to the multi-functional surface solid support 300: wherein the screen 550 has a face-shaped through-opening 200.

A frame 100 comprising a screen 550 is deposited on a multifunctional surface solid support 300. Such multifunctional surface solid support 300 is the base sheet in this embodiment. Applying passive pressure on the press; The press is located at about 45 degrees from the horizontal. The screen presents a mesh size of about 100 threads / cm.

The composition 130 was applied to the open area of the screen 550 more preferably and applied on the surface of the multifunctional surface solid support 300 using a compactor 400.

Thereby, a face shape 30 is formed which is delimited by the front line 12, which is essentially circular in accordance with FIG. 3, wherein the substrate 300 is printed on such a substrate 300, The composition 300 is located on the face image except for the under-eye zone 10 and the cheek zone 20. [

The substrate 300 printed with the pink composition 130 was then dried at 45 DEG C for 30 minutes.

The screen 520, which is a 100 mesh fabric, was stretched over the frame 700. As illustrated in FIG. 4, the divider 800 is positioned in the middle of the aluminum frame 700, separating the screen 520 into two parts. On one side of the divider 800 there is an opening for the under-eye area 10 and on the other side there is an opening for the cheek area 20. The aluminum frame 700 including the screen 520 and the divider 800 is placed on the base material 300. The screen 520 is positioned over the substrate 300 that has already been printed and dried using the composition 130 so that the apertures of the screen are positioned on the undersurface region 10 and the cheek region 20 on the substrate 300, Lt; RTI ID = 0.0 > position. ≪ / RTI > The yellow composition 110 for the under eyes 10 and the blue composition 120 for the cheeks 20 were applied on the base material 300 using the presser 600. Thereby, a facial shape scoped by an essentially circular front line 12 printed on the substrate 300 according to Fig. 5 was formed. The face printed on the substrate 300 may be printed on a composition 110 printed on the undersurface region 10, a composition 120 printed on the cheek region 20 and a composition 120 printed by the front line 12 And a composition 130 printed on the remaining face region 30. [ This substrate 300 was again dried at 45 DEG C for 30 minutes.

This substrate 300 has been shaped and designed along a line 5 in which an essentially round face mask 1 can be matched to the front line 12. The through openings for the eyes 15, the nose 35 and the mouth 25 were also shaped so that a mask 1 as shown in Fig. 1 was obtained. Here, the base material 300 was shaped by cutting means.

matter Area density (gm / m ² ) Substrate alone 50 A mask comprising three compositions 60 Composition deposition (drying) 10

The density of the dry composition of such a mask ranged from 5 gm / m ² to 70 gm / m ² .

The dry composition of each mask will vary depending on the size and dimensions of the mask; For example, we have developed a 21 cm diameter mask containing a total of 0.40 g of dry composition.

To apply to user's face; The face mask can be wetted or hydrated by dipping the face mask in water or spraying water onto the mask. When water is applied to the dry composition, the composition forms a gel-type structure, which remains in their respective locations on the multi-functional surface solid support 300. The amount of water required to wet the face mask to provide good adhesion to the skin was observed to be about 0.80 g in this specific example.

The wetted mask can be applied on the face to deliver individual gains on the subcutaneous area, the cheek area and the rest of the face area.

Due to the occlusive nature of the multifunctional surface solid support, the face mask produced can be maintained on the skin for at least 4 hours under wet conditions. The application time of the face mask should be determined according to the sensory comfort of the user and the efficacy of the product.

Thus, the present invention provides a single product consisting of two or more formulations that can be packaged and used, while avoiding mixing of formulations. The present invention provides a user-friendly way to apply several distinct topical compositions, preferably in appropriate amounts, to different areas of the user's skin. The present invention also limits the delivery of the active ingredient to the unwanted / unspecified zone (s) of the keratinous material of the individual when multiple topical compositions are applied by a single product or device in a plurality of zones . The present invention also contemplates the potential reduction of the activity of the active ingredient when multiple topical compositions are applied by a single product or device in multiple zones, Because. More generally, the present invention overcomes problems associated with the interaction of multiple topical compositions when multiple topical compositions are applied by a single product or device in multiple zones.
