Description

Technical Field

[0001] The present disclosure relates to skincare products for topical application to the skin of a user. More specifically, the present disclosure relates to a skincare product having a base layer comprising a biodegradable film and having one or more active ingredients that provide cosmetic and / or medical effects when applied to the skin of a user. The skincare product may be in the form of a face mask for direct application to the face of the user, or in the form of a patch or film for application to other areas of the skin of the user.

[0002] Healthy skin is a common goal worldwide. Consumers are seeking ways to improve the appearance and texture of their skin and address skin imperfections. For this purpose, beauty face masks are often used as a way to effectively deliver functional ingredients to the surface of the user's skin. Beauty face masks can be customized to provide specific treatments such as moisturizing, cooling, reducing blemishes, reducing wrinkles or skin firming.

Background Art

[0003] Beauty face masks are typically made of fabrics such as cotton, fiber, cellulose or pulp. The fabric is pre-cut into the required shape, most commonly the shape of the entire face, and immersed in various solutions containing beauty compounds, usually solutions called serums. The fabric is used to move and hold the beauty ingredients against the face for a desired period of time. Face masks are generally made of non-compostable, non-recyclable, non-biodegradable materials and are therefore discarded in the trash when the treatment is complete. These masks may also be made of synthetic resins that do not biodegrade and thus contribute to plastic waste.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Another problem with conventional beauty face masks is that they are inconvenient and cumbersome to use. Because the fabric is simply soaked in serum, it may not be able to hold the serum well, and some of the serum may separate from the mask while being removed from the package and while being applied by the user. Therefore, some of the serum may remain in the package or on the user's hands, and the full effect of the active ingredients in the serum may not be obtained.

[0005] There is a need for improved skincare products for topical application that can overcome the aforementioned drawbacks. [Means for solving the problem]

[0006] In one embodiment, a skincare product for topical application may include a base layer and a functional layer.

Brief Description of the Drawings

[0028] Referring to the accompanying drawings, the present invention will now be described for illustrative purposes only.

[0029] [Figure 1] FIG. 1 is a schematic view showing a layer of a skin care product according to the present disclosure.

[0030] [Figure 2] FIG. 2 shows an example of a skin care product in the form of a beauty face mask.

Mode for Carrying Out the Invention

[0031] Embodiments of the present disclosure relate to skin care products for topical application to a user's skin. As illustrated in FIG. 1, the skin care product 10 generally includes a base layer 1 and a functional layer 2 applied to one surface of the base layer 1.

[0032] Unless otherwise specified, all percentages and ratios disclosed in this specification are based on mass.

[0033] The base layer includes a flexible biodegradable film that generally contains a biodegradable polymer matrix, a water-soluble plasticizer, water, and other components. The main component of the base layer is generally a plant-based hydrocolloid derived from natural and renewable resources.

[0034] The biodegradable polymer matrix includes one or more polymer substances selected from the group consisting of polysaccharides, powders, fibrous substances, rubbers, and proteins. The polymer substances are generally plant-based, and the polymer matrix usually occupies about 35 - 80% of the composition of the base layer. More typically, the polymer matrix may occupy about 40 - 75% of the composition of the base layer.

[0035] Suitable polysaccharides are water-soluble and may be selected from one or more elements of the group including modified or unprocessed (natural) starch, potato starch, wheat starch, tapioca starch, corn starch, rice starch, pea starch, bean starch, lentil starch, pulsed starch, and mung bean starch. In examples of the base layer embodiment, rice starch and / or tapioca starch are most commonly used.

[0036] The preferred powder may be selected from one or more elements of the group including rice flour, wheat flour, soy flour, and corn flour.

[0037] Examples of fibrous materials include plant fibers such as pea fiber, rice fiber, tapioca fiber, wheat fiber, and potato fiber, and may also include cellulose.

[0038] Suitable rubbers may be selected from one or more elements of the group including carrageenan, konjac, gellan gum, agar, guar gum, locust bean gum, xanthan gum, carboxymethylcellulose, and alginate. In examples of base layer embodiments, carrageenan is most commonly used.

[0039] The protein may be derived from natural sources, and may be of animal or plant origin. Suitable plant proteins may be selected from one or more elements of the group including soy protein, rice protein, pea protein, mung bean protein, hemp protein, pumpkin seed protein, and plant-like proteins.

[0040] In some embodiments, the polymer matrix of the base layer composition consists of one or more starches and rubbers such as carrageenan. In such embodiments, the polymer matrix is ​​primarily starch-based. For example, the starch:rubber mass ratio may be in the range of about 2:1 to about 30:1, or, based on mass%, starch may constitute about 70 to 98% by mass of the polymer matrix components.

[0041] Suitable plasticizers for use in the base layer may be selected from one or more elements of the group including glycerin (also known as glycerol), sorbitol, hyaluronic acid, sodium lactate, and natural humectants such as honey. In some embodiments, propylene glycol may be used as a plasticizer. Most embodiments use glycerin as a plasticizer, which may be of natural origin, such as palm. The plasticizer typically constitutes about 10–30%, more commonly about 15–25%, of the base layer composition.

[0042] The water content of the base layer is typically around 5-15%, for example, about 10%. This is the water content of the film after drying.

[0043] The base layer film composition may include one or more other components, such as oils, fragrances, flavorings, and colorants. Suitable oils include coconut oil and palm oil, which may be present in the base film in an amount ranging from about 2% to 7%.

[0044] The base layer film may offer a wide range of thicknesses, with the dry thickness of the base layer film being approximately 10–150 microns or approximately 10–120 microns, typically around 25–70 microns, and more commonly around 40–60 microns.

[0045] The base layer film can be manufactured by solution casting or extrusion molding.

[0046] In the solution casting method, some or all of the above-mentioned base film components, such as rubber, starch, oil, fiber, protein, and plasticizer, are mixed with water at an increasing temperature to form a homogeneous solution. The solution typically has a target viscosity of about 6,000 to 15,000 cps. The solution may also contain colorants, flavorings, and / or fragrances as needed. The solution is cast onto a continuous belt or foil and dried until it has the required moisture content and uniform thickness. The film may be compounded to have tensile strength and elongation properties as needed for the intended application and may be slit, cut, and / or stamped to any required size and shape.

[0047] The following table shows exemplary values ​​for the tensile strength and elongation of the face mask base film, both before drying ("wet") and after drying ("dry"). It can be seen that these mechanical properties improved after drying the film. [Table 1]

[0048] In extrusion molding, the components of the dried film are pre-mixed to form a dry blend, which is then fed into the mixer of the extrusion molding machine in a one- or two-step process.

[0049] In a single-step process, the dry blend is fed into an extruder and mixed with liquid film components such as water and / or glycerin in various heating zones and at the required screw speed to form a molten composition. Next, the molten composition is fed into a film die and the extruded base film is dried to the required moisture content. The dried base film can be further processed into rolls or sheets as needed.

[0050] In a two-stage process, the film components are first pre-mixed, then fed into an extruder and mixed under a specific set of conditions, including temperature and screw speed, to form a molten composition. This is then extruded through a tubular die to form a consistent tube, which is then cut into smaller sizes, commonly called pellets.

[0051] Next, the pellets are put back into the extruder, melted, and pressed through a flat or tubular die of a suitable size to obtain the desired film thickness, and the extruded base film is dried to the required moisture content. The dried base film can be further processed into rolls or sheets as needed.

[0052] The choice between a one-stage or two-stage extrusion process depends on the type of compound used and their hydration rate.

[0053] After preparing the base film and drying it to a suitable moisture content, a functional layer containing one or more active ingredients that provide cosmetic and / or medical effects when applied to the user's skin surface can be provided. In use, the base film layer faces away from the user's skin, while the functional layer faces the user's skin and comes into direct contact. The thickness of the functional layer is approximately 25-50 microns, more typically about 35-40 microns.

[0054] The active ingredients in the functional layer may provide one or more effects to the user's skin, such as moisturizing, cooling, soothing, whitening, blemish suppression, relief of insect stings or bites, skin tightening or firming, and cellulite suppression. These effects may be for cosmetic and / or medical purposes. Exemplary formulations for various functional layers are shown in the examples.

[0055] To provide the range of effects described above, a wide variety of active ingredients may be provided within the functional layer. Examples of active ingredients include hyaluronic acid, ceramide, aloe vera, menthol, chamomile, pentavitin, niacinamide, peppermint oil, witch hazel, salicylic acid, tea tree oil, colloidal oatmeal, hydrocortisone, pullulan, caffeine, and vitamin C. Additionally, the active ingredients may include natural extracts such as peony root extract, centella asiatica extract, and citrus fruit extracts.

[0056] For example, if the skincare product is intended for use as a face mask, the active ingredients may include one or more of hyaluronic acid, ceramide, salicylic acid, and natural extracts.

[0057] If the skincare product is a cooling film, the active ingredients may include one or more of menthol, aloe vera, and natural extracts.

[0058] If the skincare product is an insect bite film, the active ingredients may include one or more of colloidal oatmeal, hydrocortisone, and natural extracts.

[0059] If a skincare product is for skin tightening, the active ingredients may include one or more of hydroxypropyl methylcellulose, pullulan, hydrolyzed collagen and elastin, and natural extracts.

[0060] In some embodiments, the functional layer may be applied to the base film layer in the form of a liquid slurry. The slurry is applied to the base film layer to the required thickness and then dried. In other embodiments, the functional layer may be applied on top of the base film layer by roll coating or spray coating.

[0061] To ensure the functional layer is smooth and to regulate the dissolution rate of the mask during moisturizing and application to the skin, the functional layer may further contain one or more film-forming compounds. These film-forming compounds in the functional layer may include any of the above-mentioned film-forming compounds in the base layer, i.e., a biodegradable polymer matrix, a water-soluble plasticizer, water, and any of the other components mentioned above. For example, the biodegradable polymer matrix may be selected from the group including polysaccharides, powders, fibrous materials, rubber, and proteins. For example, the functional layer may contain glycerin, water-soluble starch, and alginate.

[0062] Other ingredients that may be included in the functional layer include oils, fragrances, flavorings, and colorants, as mentioned above.

[0063] The skincare product may include an optional third layer, which may have a non-aqueous composition. The third layer is identified as layer 3 in Figure 1. In some embodiments, the third layer contains an oil such as coconut oil, avocado oil, or jojoba oil. This third layer is applied on top of the functional layer, sandwiching the functional layer between the base film layer and the functional layer. The arrows in Figure 1 indicate the direction facing the user's skin when the skincare product is first applied to the skin, and thus the third layer comes into direct contact with the user's skin. The third layer is absorbed and / or dispersed in the skin, exposing the functional layer to the skin surface.

[0064] The presence of a non-aqueous third layer as a surface coating offers one or more advantages, such as providing ease of handling to avoid loss of the functional layer before or during application to the skin, allowing the user to manipulate the product to optimally position it on a desired area of ​​the user's skin due to its oily nature, avoiding loss of the functional layer during moisturizing of the skincare product, and / or further enhancing the intended skin treatment, for example by providing skin moisturizing properties.

[0065] Typically, any third layer is a coating that is usually lighter and thinner than either the functional layer or the base film layer. The third layer may be applied by spraying onto the exposed surface of the functional layer. To allow the third layer to be rapidly absorbed and / or dispersed when applied to the user's skin, the third layer may have a thickness of about 5 to 20 microns, more typically about 10 to 15 microns.

[0066] After the layers are formed and dried, the resulting product is usually in the form of a flat sheet, and the exact size and dimensions usually depend on the method of forming the base film layer. Individual skincare products are then provided by cutting and / or stamping the flat sheet product with one or more dies. For example, as shown in Figure 2, if the skincare product 10 is a face mask, the flat sheet product is cut or stamped to define one or more pieces that define the outer edge 12 of the face mask and holes for the user's eyes 14, nose 16, and / or mouth 18. The flat sheet product may be cut and / or stamped into various shapes and sizes depending on the application of the skincare product. For example, the flat sheet product may be cut and / or stamped into patches of various sizes for application under the eyes, or for application to other areas of the body to treat insect bites, blemishes, or any other treatment described herein.

[0067] After being cut and / or stamped into the desired shape, the skincare products are packaged for sale. Because the skincare products are packaged in a dry state, there is less possibility of degradation of the functional layer and / or any of the active ingredients contained therein due to prolonged aqueous storage, which can be a problem with conventional "wet" masks. In addition, the dry nature of the product simplifies handling and application by the user and reduces the amount of functional layer and / or active ingredients remaining in the packaging.

[0068] Skincare products may be briefly moistened with water after being removed from their packaging by the user and before being applied to the user's skin. Moisturizing is useful for activating the functional layer and / or improving the flexibility, applicability, and / or adhesion of the skincare product to the user's skin.

[0069] The face mask products described herein are typically moisturized before use, but moisturizing is not always necessary, and it will be understood that some of the skincare products described herein may be applied directly to the skin after being removed from the packaging.

[0070] Once skincare treatment is complete, the skincare product is removed and discarded by the user. Because the components constituting the base film are biodegradable and / or soluble, the skincare product may be disposed of in an environmentally friendly manner, for example, by dissolving it in warm water and pouring it down the sink, or by adding it to a compostable waste pathway. Unlike conventional cloth-based face masks, for example, the face mask according to this disclosure does not leave behind long-lasting solid waste, making it more appealing to environmentally conscious consumers. Due to the desirable properties of the skincare product according to this disclosure and the selection of natural ingredients for the base layer, functional layer and any other layer, certain embodiments of the skincare product may be advertised as vegan, paraben-free, sulfate-free, mineral oil-free, petrolatum-free, and / or silicone-free.
