Description

Technology Field

[0001] The present invention relates to a skin-attached patch for weaning care of nursing mothers. Background Technology

[0002] Recently, the market for childbirth and breastfeeding has been expanding, and various products designed with the health and convenience of new mothers in mind are being developed. In particular, as many women experience various discomforts such as breast engorgement, fever, pain, and mastitis during the weaning process, there is a growing demand for assistive devices to alleviate these issues. For instance, traditionally, methods primarily involved using heat therapy or cooling packs to relieve pain and compression bras to regulate milk flow. However, these methods often caused skin irritation with prolonged wear or were ineffective because they did not adhere properly to the shape of the breast.

[0003] Furthermore, some breastfeeding aids currently on the market are composed of polymer gels or powders. While they can provide a temporary cooling effect, prolonged use attached to the skin can cause irritation and hygiene issues. In addition, there is a relative lack of products that help regulate female hormone balance or combine soothing and moisturizing effects. Moreover, the patches often fail to adhere closely to the curves of the mother's breasts, resulting in poor comfort during outdoor activities. Therefore, there is a need for the development of a patch-type product that minimizes pain and skin irritation during the weaning process, maintains a secure fit even with long-term wear, and provides both cooling and soothing effects simultaneously.

[0022] Specific embodiments will be described below with reference to the attached drawings.

[0023] FIG. 1 is a schematic diagram showing a skin-attached patch for weaning care of a nursing mother according to one embodiment, FIG. 2 is a schematic diagram showing a cross-section of a skin-attached patch for weaning care of a nursing mother according to one embodiment, FIG. 3 is a schematic diagram showing a protective film layer of a skin-attached patch for weaning care of a nursing mother according to one embodiment, and FIG. 4 is a schematic diagram showing a location for attaching a skin-attached patch for weaning care of a nursing mother according to one embodiment.

[0024] Referring to FIGS. 1 to 3, a skin-attached patch (10) for weaning a nursing mother according to one embodiment of the present invention forms an overall surface area in the form of a wide sheet, but can be implemented in various shapes such as a curved circle, oval, or square. In addition, it is equipped with elasticity corresponding to the curve of the skin so as to adhere closely to the breast skin, thereby minimizing lifting or wrinkles in the curved parts of the skin when the patch is worn. For example, if an elastic material or elastic fiber is applied to the support layer or the active ingredient layer, the shape can be naturally deformed according to the outer curve or curvature of the breast and it can be stably attached, and the patch does not fall off according to the user's movements during daily life and is maintained in a comfortable state.

[0025] A skin-attached patch (100) for weaning a nursing mother according to one embodiment is implemented by laminating a support layer (100) that serves as a base layer, an active ingredient layer (200) formed of a hydrogel, and a protective film layer (300) for protecting the active ingredient layer (200). When attached, the patch (10) adheres to the breast skin and can provide moisturizing, soothing, and cooling functions.

[0026] The support layer (100) is a base layer that supports the overall shape of the patch and provides physical stability to the patch.

[0027] The active ingredient layer (200) is placed on the support layer (100) and is a layer that actually comes into contact with the skin. The active ingredient layer (200) can be formed with purified water and active ingredients including menthol, glycerin, sage oil, etc., and provides cooling, moisturizing, and soothing effects to the skin. Accordingly, it alleviates pain, heat sensation, and discomfort that occur during the weaning process.

[0028] The protective film layer (300) consists of a release paper that protects the active ingredient layer (200) from the external environment. The protective film layer (300) prevents the active ingredient layer () from drying out or becoming contaminated until the user attaches the patch and uses it. When using, the protective film is removed, and the active ingredient layer (200) is applied directly to the skin.

[0029] Referring to FIG. 4, the patch (10) is attached to the skin of the breast area of ​​a nursing mother who is weaning, and the patch can reduce skin irritation and provide a cooling effect and relieve pain due to the action of the active ingredient layer. The entire patch adheres stably to the breast area and does not fall off or slip down during daily life.

[0030] In addition, the active ingredient layer (200) of the patch (10) uses a mildly acidic, low-irritation material to minimize skin trouble and continuously supply active ingredients, which can help with moisturization and pain relief during weaning. The active ingredient layer (200) maintains a pH of 4.5 to 6.2, and preferably maintains a pH of 5.3, so that the acidity of the patch is set close to the acidity of the human body so that there is less irritation even when the patch (10) is in contact with the skin for a long time. Accordingly, by maintaining a pH of around 5.3, taking into account the characteristics of sensitive skin or the breast skin of a nursing mother, the skin barrier can be protected and hygiene can be enhanced.

[0031] The active ingredient layer (200) comprises, with respect to 100 parts by weight of purified water, which is the main solvent and is included for uniform dispersion of water-soluble components and for skin moisturization, 0.1 to 1 part by weight of tartaric acid (L(+)-Tartaric acid) to adjust the pH of the product, exfoliate, and stabilize acidity; 0.1 to 1 part by weight of hydroxyacetophenone to provide antioxidant action, increase preservation stability, and alleviate skin irritation; 0.02 to 0.6 parts by weight of pyridoxine hydrochloride for skin conditioning and health promotion; 0.1 to 2 parts by weight of sodium carboxymethyl cellulose (CMC) to adjust viscosity within the patch and induce gelation to improve applicability; and 10 parts by weight of glycerin to strengthen skin moisturization, maintain moisture, and protect the skin barrier. ~ 60 parts by weight, including 3 to 20 parts by weight of sodium polyacrylate to control viscosity, absorb and retain moisture, and maintain the elasticity of the hydrogel, including 0.1 to 1 part by weight of dihydroxyaluminium aminoacetate to maintain the pH and improve the physical stability of the product, including 0.1 to 1 part by weight of disodium edetate (EDTA) to bind metal ions to prevent oxidation and deterioration of the product and to enhance shelf life, including 0.01 to 0.4 parts by weight of kaolin to soothe the skin and absorb sebum to enhance skin protection, including 0.01 to 0.4 parts by weight of titanium dioxide to control the patch color and provide partial UV protection, and to provide a cooling sensation to the skin and alleviate breast pain occurring during weaning, Menthol 0.It may contain 0.5 to 3.3 parts by weight, 1 to 10 parts by weight of propylene glycol to act as a moisturizer and solvent and to promote skin absorption of other ingredients, 0.2 to 4 parts by weight of polysorbate 80 to maintain emulsion stability and homogeneous mixing among ingredients in the product, and 0.02 to 0.6 parts by weight of clary sage oil for regulating female hormone balance, soothing the skin, and inhibiting milk secretion during weaning.

[0032] In addition, in some embodiments, the active ingredient may further include 0.01 to 2 parts by weight of lanolin for skin moisturization, soothing, and improvement of skin flexibility.

[0033] Lanolin is a naturally derived lipid extracted from sheep's wool that offers excellent moisturizing and barrier-forming effects, making it suitable for use in skincare products. In particular, utilizing lanolin in products for nursing mothers can help form a protective barrier on the skin surface to inhibit moisture evaporation and maintain hydration for extended periods. It can alleviate discomfort by providing moisture to skin (such as nipples or breasts) that has become cracked or sensitive during nursing or the weaning process. Furthermore, lanolin protects the skin from external stimuli and contributes to soothing irritated areas. When applied to the skin for a certain period in the form of a patch, it reinforces the skin barrier, which is beneficial for reducing irritation. Additionally, the emollient properties of lanolin soften dry or damaged skin, which can help improve adhesion when wearing the patch. When breast skin becomes sensitive during the weaning process, patches containing lanolin can alleviate dryness or cracking. Moreover, superior moisturizing and soothing effects can be expected when lanolin is used in combination with other moisturizing ingredients, such as hydrogel or glycerin.

[0034] In some embodiments, lanolin is obtained by grinding wool to a size of 80 to 120 mesh (approx. 0.125 to 0.177 mm), using anhydrous ethanol as an extractant to mix the wool in a ratio of 1:5 to 9, and performing ultrasonic extraction treatment for 50 to 70 minutes at a power output of 55 to 65 W in a temperature range of 35 to 45°C. In this process, the cavitation effect of the ultrasound can improve extraction efficiency by breaking down the lanolin molecular bonds within the wool. After ultrasonic extraction, impurities are removed through filter paper, and a concentrate is extracted using a rotary evaporator at 45 to 55°C. The extracted concentrate is then bleached by adding 4% to 6% hydrogen peroxide at 55 to 65°C and stirring for 25 to 35 minutes, and finally, dried at room temperature.

[0035] In addition, in some embodiments, the active ingredient may further include 0.01 to 2 parts by weight of acai berry extract to provide anti-inflammatory and anti-aging skin effects by containing antioxidant substances such as anthocyanin and vitamin C.

[0036] The following process can be performed to apply the acai berry extract to the patch (10) according to the present invention. First, a multi-stage extraction and fractionation process is performed. After washing and thawing fresh or frozen acai berries, the washed acai berry raw material is mixed with water at a temperature of 50 to 60°C in a ratio of 1:3 to 8 (weight ratio), and stirred and immersed for about 3 to 5 hours. Afterward, a primary extract is obtained through filtration or centrifugation. The primary extract is concentrated under reduced pressure at 50 to 60°C using a rotary vacuum evaporator to evaporate the water. The concentrate is fractionated stepwise with water, a polar solvent, and hexane or ethyl acetate, a non-polar solvent, to separate a polar layer rich in antioxidants, anthocyanins, and polyphenols from a non-polar layer containing oil components. The polar layer fraction can be utilized in a liquid state or freeze-dried to produce acai berry fraction extract in powder form.

[0037] Next, fermentation and aging processes are performed. A liquid fraction or acai berry fraction is mixed in a water mixer adjusted to a temperature range of 25 to 35°C and a pH of 4 to 5, and fermentation strain inoculation is performed by inoculating lactic acid bacteria (Lactobacillus genus) at a level of 10^5 to 10^7 CFU / mL. Fermentation conditions involve carrying out fermentation for 12 to 48 hours at a temperature range of 25 to 35°C. After fermentation is complete, microbial residues or precipitates are removed through centrifugation and filtration, and the mixture is subsequently aged for 10 to 12 weeks at a low temperature of 5 to 10°C to induce stabilization and enhancement of active ingredients. The final fermented and aged liquid can be concentrated or powdered, and contains organic acids and decomposition products (improving skin absorption, enhancing whitening and moisturizing effects) generated during the fermentation process. Through this fermentation and aging process, the polyphenol and anthocyanin components unique to acai berries are hydrolyzed or modified by microbial enzymes, which can improve skin absorption rates and physiological activity.

[0038] Next, a dispersion and emulsion process is performed. An aqueous phase is prepared by mixing purified water and glycerin with a fermented and aged acai berry extract (or a liquid obtained by redissolving the powder) as the main ingredient and adjusting the pH to 5.0 to 5.5. An oil phase is prepared by mixing lanolin (pre-treated lanolin) in a ratio of 1:1 to 2 relative to the acai berry extract and adding a small amount of an emulsifier (e.g., polysorbate). The oil phase, heated to 40 to 50°C, is slowly dripped onto the aqueous phase while stirring. At this time, high-shear mixing is performed at 5,000 to 20,000 rpm to form fine emulsions with a size of 50 to 200 nm. Afterward, while cooling the mixture to 25 to 30°C, a polymeric thickener such as CMC (Carboxymethylcellulose) or carrageenan is added to increase the viscosity. Once the emulsion droplet size is stably maintained, a lanolin-based complex emulsion containing acai berry fermented extract can be obtained. The emulsion obtained in this way can be easily dispersed in the hydrogel (aqueous matrix) of the active ingredient layer (200) of the patch (10), and upon contact with the skin, the antioxidant effect of the acai berry and the highly moisturizing effect of the lanolin are simultaneously exhibited.

[0039] In this way, to utilize the acai berry component with higher functionality, a multi-stage extraction and fractionation process, a fermentation and aging process, and a dispersion and emulsification process are performed, and then combined with lanolin to be used as an active ingredient for a patch. Through this, a skin-attached patch (10) for weaning care of a nursing mother is designed to provide the powerful antioxidant and skin vitality-enhancing effects of acai berry and the excellent moisturizing and skin barrier protection effects of lanolin.

[0040] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing the technical concept or essential features thereof. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. Explanation of the symbols
