Description

Hydrogel eye patch that becomes an eye patch when separated {Hydrogel eye patch}

The present invention relates to a hydrogel eye patch that becomes an eye patch when separated, and more particularly, a cutout is formed in the center of the eye patch patch to which a hydrogel functional composition is applied to give a cooling feeling to the user's skin, It relates to a hydrogel eye patch patch that, when separated, becomes an eye patch, which optionally allows the eye patch patch to be separated into a pair of eye patches as the cutouts are cut.

In case of eye strain, dry eye syndrome, or inflammation in the eye area, cold packs around the eyes are effective. For these eye patch-type cold packs, put the cold pack in the freezer and put it in the receiving space of the eye patch-type pouch while the cold pack is cold. Since it is made in the form of an eye patch, the cold pack in the form of an eye patch is worn around the eyes to apply cold compresses. These eyepatch-type products inevitably include an elastic wearing band that is worn over the ear or wrapped around the head, so that the cold pack must be fixed around the user's eyes. However, such a wearing band is not cost-effective to attach and detach by the wearing band, and inconvenience due to the protrusion of the wearing band occurs.

On the other hand, the eye patch is a film similar to wound plast, and was made to treat some eye diseases or to solve problems with the skin around the eyes. The eye patch is formed in a half-moon shape and is attached to the eye area, especially the lower part of the eye, to partially impart effects such as brightening, nutrition, moisturizing, cooling, soothing, and elasticity. In particular, it is mainly used to improve dark circles under the eyes, which are caused by staying up at night, eye fatigue (astheopia), or aging (senility), and blood flows too slowly in the blood vessels of the eye skin. caused by stagnation caused by At this time, it is possible to relieve eye fatigue and the like through cold compresses around the eyes or under the eyes. In other words, the eye patch type cold pack and eye patch can achieve the desired results through the same cold pack.

However, the conventional eye patch-type cold pack and eye patch were manufactured and sold only in the form of a separate eye patch-type cold pack for the eye area and a separate eye patch for the lower part of the eye, respectively. No product has been developed that can achieve the desired results for each of the eye patches.

1 is a view showing a hydrogel eye patch 1000 that becomes an eye patch when separated according to the present invention, and FIG. 2 is a hydrogel eye patch 1000 that becomes an eye patch when separated according to the present invention around the user's eyes 3 is a view showing a state attached to the lower side of the user's eyes after the hydrogel eye patch 1000, which becomes an eye patch when separated according to the present invention, is detached according to the present invention.

According to the present invention, the hydrogel eye patch 1000 (hereinafter referred to as 'eye patch'), which becomes an eye patch when separated, is attached around both eyes of the user, and is attached to the user's eyes with reference to FIGS. An eye patch that has a long shape from side to side to cover both eyes, and a hydrogel functional composition is applied on one or both sides to give a cooling feeling to the user's skin, especially around both eyes ( 1000) are included. The eye patch 1000 provides comfort to the eyes due to a cooling feeling and helps with dry eye syndrome.

The eye patch 1000 according to the present invention has an elongated shape to cover both eyes of the user. The eye patch 1000 may be made of a material such as cloth, and for example, may be made of a material such as a non-woven fabric, a woven fabric, or a knitted fabric, but is not limited thereto. It may be a manufactured patch.

The reason for using polyurethane is that it has good elasticity, is harmless to the human body, and can be freely deformed according to the shape of the curve of the skin, and can suppress moisture evaporation. In addition, the reason for using cotton is that it maintains close adhesion with the skin, is safe for the skin in contact with, and functions as a hydrogel for a long time by absorbing the hydrogel sufficiently, and at the same time, it can be stored for a long time. Polyurethane and cotton are mixed to produce the eye patch 1000, and as polyurethane is provided between the side and the surface, the eye patch 1000 has elasticity, and thus can be freely stretched and contracted without damage to the eye patch 1000 can On the other hand, in order to colorize the eyepatch patch 1000 according to the present invention, it is dyed with a selected color set in advance on polyurethane or cotton before the manufacture of the eyepatch patch 1000, or is set in various ways after the manufacture of the eyepatch patch 1000 It can be used by dyeing the corresponding color. In addition, a mark such as a specific logo, character, or trademark may be printed and used on one or both sides of the eye patch 1000 .

The eye patch 1000 according to the present invention adheres and adheres to and adheres to the user's face, particularly around both eyes, around the eyes, or under the eyes through the functional hydrogel composition, so it has porosity and elasticity. It is preferable to have That is, a plurality of through holes may be formed in the eye patch 1000 so that the functional hydrogel composition can easily penetrate therethrough.

The functional hydrogel composition is applied to the eye patch 1000 according to the present invention to provide a cooling feeling to the user's skin and to provide an adhesive force that can be attached to the user's skin. As the functional hydrogel composition, a known one may be used, and examples thereof will be described later.

The eye patch 1000 according to the present invention includes a cut-out portion 101 that can be cut in the vertical direction according to the user's selection at a portion located on the user's nose when it is attached around both eyes. The cutout 101 may be formed through, for example, a known punching process, so that a user can easily cut and separate the eye patch 1000 into two. The eye patch 1000 becomes a pair of eye patches 100 as the cutout 101 is cut by the user and separated into two parts. The pair of eye patches 100 are attached and adhered to the lower side of the user's eyes, respectively, so as to provide effects such as improvement of wrinkles around the eyes of the user, whitening, antioxidant, blemishes under the eyes, and freckle relief. Meanwhile, the pair of eye patches 100 at this time may be formed to have a shape symmetrical to each other with respect to the cutout 101 .

Each of the eye patches 100 according to the present invention includes a front part 110 and an extension part 120 . The front part 110 is positioned on the user's eyes and covers the eyes when the eye patch 1000 is attached around the user's eyes before the cutout 101 is cut out. The extension part 120 is formed to extend from both ends of the front part 110 and is attached to the side surface of the user's face.

The eye patch 1000 according to the present invention is attached to the user's face through the adhesive force of the functional hydrogel composition without means such as a string for fixing to the user's face. The extension 120 may be formed to have a 'V' shape lying on its side to be in close contact with the side of the user's face when it is attached to the user's face.

The extension part 120 according to the present invention includes a first extension member 121 and a second extension member 123 . The first extension member 121 is positioned above the second extension member 123 , and the second extension member 123 is positioned below the first extension member 121 . The first extension member 121 and the second extension member 123 are formed so that the distance between them gradually increases as they extend outwardly, so as to have a 'V' shape lying on their side as described above. Accordingly, it can be more closely attached to the side of the user's face having a curved shape or a curve.

Meanwhile, the first extension member 121 is formed to extend outwardly longer than the second extension member 123 . This is to further improve adhesion with the side of the face by the first extension member 121 positioned higher than the second extension member 123 when the extension part 120 is attached to the side surface of the face.

The end of the first extension member 121 formed to extend outwardly longer than the second extension member 123 may be formed to be bent inwardly to have a predetermined angle. This is a configuration for the first extension member 121 to be adhered to the side of the face avoiding sideburns when the eye patch 1000 is attached around the eyes, and has the effect of further improving the adhesive force of the extension 120 on the side of the face. have.

On the other hand, when the functional hydrogel composition is coated by applying the functional hydrogel composition to the surface of the eye patch 1000 as a molecular structure of a sol state is formed by mixing the components of the liquid phase, the hydrogel composition is It flows down or separates from the eye patch 1000 so that the functional hydrogel composition is smeared on other parts of the body, such as the hand, while the user uses the product. Therefore, after applying the functional hydrogel composition to the surface of the eye patch 1000 to a certain thickness, a release film is attached to one or both sides of the eye patch 1000 to which the functional hydrogel composition is applied. The eye patch 1000 and the release film may be laminated through a rolling machine so that the release film can adhere to the patch. After the release film is attached, it is aged for a certain time and then dried to form a functional hydrogel composition in a sol state into a functional hydrogel in a semi-solid state. When applying the functional hydrogel composition, it is compressed with two rollers while injecting the functional hydrogel composition between the two rollers so that it flows between the eye patch 1000 and the release film, and after coating the functional hydrogel composition, the Cool to temperature to allow gelation to proceed. At this time, in order to form the functional hydrogel composition undergoing gelation in a semi-solid state, it is left at room temperature for 12 to 24 hours and then aged at 43 to 45° C. for 2 to 4 days, and the aged functional hydrogel is 1-3 It is dried at 22~28℃ daily to finish curing. If the drying period is less than 1 day, the viscosity is too much and it is cumbersome to use on the skin, and if it exceeds 3 days, the viscosity is too low, causing inconvenience such as easily falling off when used.

Functional hydrogel composition according to the present invention, purified water, glycerin, dipropylene glycol, carboxymethyl cellulose sodium, agar, tartaric acid, xanthan gum, sodium polyacrylate, polyacrylic acid, aluminum glycinate, disodium editi A hydrogel composition can be prepared by mixing A. At this time, the content ratio of the hydrogel composition is 25 to 35% by weight of glycerin, 2 to 10% by weight of dipropylene glycol, 0.001 to 1% by weight of sodium carboxymethylcellulose, 0.5 to 5% by weight of agar, 0.01 to 1% by weight of tartaric acid , xanthan gum 0.001 to 1% by weight, sodium polyacrylate 1 to 10% by weight, polyacrylic acid 2 to 10% by weight, aluminum glycinate 0.01 to 0.5% by weight, disodium EDTA 0.01 to 0.5% by weight, fragrance 0.01 to 0.1% by weight, the remaining amount may be formulated by mixing purified water.

Glycerin and dipropylene glycol maintain the moisture balance and act as a moisturizing and softening agent. In particular, glycerin serves to enhance spreadability (applicability) by imparting viscosity, and forms a protective film on the skin. In the present invention, 25 to 35% by weight of the glycerin is mixed in the hydrogel composition, but when used in an amount of less than 25% by weight, the curing of the gel proceeds quickly and the gel cannot be smoothly coated on the support, that is, the patch. There is a problem that the shape of the product becomes irregular after curing because it does not form a flat gel even though it is used in excess of 35% by weight, the curing progress is slowed down, the gel may come out of the patch, and it is difficult to proceed with curing. To this end, there is a problem in that the gel flows out to either side during the heat treatment process or the drying process, so that the thickness of the gel is not constant. Agar is a viscous complex polysaccharide mixture extracted by physical and chemical treatment using seaweed of the agaraceae family as the main raw material, and has the effect of purifying the blood of a cold person and normalizing the secretion of hormones. Tartaric acid and xanthan gum play a role in regulating the gelation rate, and especially, tartaric acid plays a role in soothing and smoothing the skin, and has the same effect as a non-steroidal anti-inflammatory drug, thus relieving skin troubles or acne. Sodium polyacrylate makes the skin texture soft and smooth, and plays a role in maintaining moisture. Polyacrylic acid (polyacrylic acid) is preferably used alone, but polyacrylic acid, polymethacrylic acid, polyacrylic acid copolymer, polymethacrylic acid copolymer, etc. may be used alone or in combination. In the present invention, 2 to 10% by weight of polyacrylic acid is mixed in the hydrogel composition, but when used in an amount of less than 2% by weight, the desired adhesive strength is not derived from the product, so when the product is worn, There is a problem that a pushing phenomenon occurs, and when used in excess of 10% by weight, the pH is lowered and may cause irritation to the skin, and there is a problem in that the adhesive strength is upward and the strength of the gel is lowered, so that residues are left on the skin. In most conventional hydrogels, the content of glycerin is about 10% to mid-range, and the content of polyacrylic acid is about 40 to 60% by weight, but the hydrogel of the present invention contains 25 to 35% by weight of glycerin, polyacrylic acid 2 to 10% by weight of the acid is mixed. The reason is that, compared to hydrogel patches using conventional polyacrylic acid as the main raw material, the pH of the product is improved by changing the main raw material for improving the moisturizing power, which is a major problem of the conventional formulation, and improving the adhesion from polyacrylic acid to sodium polyacrylate. This is to make it possible to alleviate skin irritation more than conventional patches by raising the skin. Disodium EDTA binds to metal ions and prevents them from catalyzing their catalytic action. It blocks the activity of metal ions that are highly likely to be mixed with ingredients used in cosmetic manufacturing and manufacturing processes, thereby improving the quality of cosmetics. It plays a role in preventing deterioration of quality and rancidity. In addition, it acts as an accelerator to help effective skin absorption of active ingredients.

The mixing process of the hydrogel composition is a first step of adding purified water and disodium EDTA to a mixer to dissolve, adding purified water and agar heated to 95° C. or more to the dissolved solution and stirring, glycerin and sodium carboxymethyl cellulose After mixing and stirring xanthan gum, this stirring solution is added to the stirring solution of the first step and stirred in the second step, purified water and tartaric acid are mixed and stirred, and then this stirring solution is added to the stirring solution of the second step and stirred In the third step, glycerin, dipropylene glycol, and sodium polyacrylate are mixed and stirred, and then this stirring solution is added to the stirring solution of the third step and stirred. A fifth step of defoaming after adding acid and stirring, glycerin and aluminum glycinate are mixed and stirred, and then this stirring solution is added to the stirring solution of the fifth step, followed by a sixth step of stirring.

The functional hydrogel composition according to the present invention may include a known hydrogel polymer that can give a cooling feeling to the user's skin. Hydrogel polymers include, for example, suitable crosslinked water-swellable acrylic copolymers, and in certain embodiments, the hydrogel comprises (meth)acrylic acid, maleic acid, 2-(meth)acrylamido-2-methyl Propane sulfonic acid, styrene sulfonate, vinyl sulfonic acid, and their corresponding ammonia, amine and alkali metal salts, (meth)acrylamide, vinyl alcohol, vinyl acetate, maleic anhydride, alkyl vinyl ethers, vinylmorpholinone, vinylpyridine N,N'-methylenebis(meth)acrylamide, (poly)ethylene glycol di(meth)acrylate and a copolymer comprising repeating units from one or more monomers selected from , vinyl pyrrolidone, and acrylonitrile; (poly)propylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, glycerol tri(meth)acrylate, glycerol acrylate methacrylate, ethylene-oxide-modified trimethylolpropane tri(meth) ) acrylate, pentaerythritol tetra (meth) acrylate, dipentaerythritol hexa (meth) acrylate, triallyl cyanurate, triallyl isocyanurate, triallyl phosphate, triallylamine, poly (meth) allyloxyalkane, (poly)ethylene glycol diglycidyl ether, glycerol diglycidyl ether, ethylene glycol, polyethylene glycol, propylene glycol, glycerol, pentaerythritol, ethylenediamine, ethylene carbonate, propylene carbonate, one or more crosslinking agents selected from polyethyleneimine, glycidyl (meth)acrylate, diallyl sucrose, triallyl sucrose triallyl amine, and triallylmethyl ammonium chloride. In the present invention, the hydrogel may be used without limitation as long as it has water-soluble or ionic material permeability and has appropriate mechanical properties. Examples of the hydrogel include agar, polyethylene glycol diacrylate (PEGDA), poly(2-hydroxyethyl methacrylate) (PHEMA), alginic acid, for example, sodium alginate, calcium alginate, or potassium alginate. .

The functional hydrogel composition according to the present invention may further include centella asiatica and ceramide in order to calm the user's facial skin, supply moisture and restore the skin barrier.

Centella asiatica has been widely used as a medicinal plant in Asia, and in particular, it has anti-inflammatory, collagen synthesis and skin regeneration effects. Centella asiatica included in the functional hydrogel composition according to the present invention may be included in the functional hydrogel composition after being treated by ultrasonic waves for a certain period of time. Meanwhile, in order to treat Centella asiatica according to the present invention by ultrasonication, the content of physiologically active substances and antioxidant activity of Centella asiatica according to the ultrasonic treatment time were compared and analyzed.

After adding 80% methanol to Centella asiatica, the ultrasonic intensity was set to 200 W and treated for 5, 10, and 20 minutes. The triterpene glycosides of Centella asiatica madecassoside and asiaticoside were significantly increased in the 10- and 20-minute treatment groups. Total polyphenol content and total flavonoid content were the highest in the 20-minute treatment group, 2.3 and 2.2 g/100g, respectively. The total chlorophyll content showed the highest value at 10 minutes of treatment time. The vitamin C content was the highest in the 10-minute treatment group, and accordingly, DPPH and ABTS radical scavenging and reducing power also showed the highest activity in the 10-minute treatment group. As a result, it was found that the antioxidative activity of Centella asiatica was excellent at 10 and 20 minutes of ultrasonic treatment time. Therefore, the functional hydrogel composition according to the present invention includes Centella asiatica treated with ultrasonic waves for 10 to 20 minutes.

The ceramide contained in the functional hydrogel composition according to the present invention is one of the three main lipids of the stratum corneum of the epidermis, which is the outermost layer of the skin. The stratum corneum of the epidermis, which is the outermost layer of the skin, is composed of three main lipids, namely, ceramide, free fatty acid, and cholesterol, which are 50%, 25%, and 25% respectively. It plays a role in absorption and prevention of microbial infection. Ceramide composed of lipid components accounts for 35-40% of intercellular cement between cells and is related to hydration of the skin. ) increases, the skin becomes dry, the surface becomes dry, and dead skin cells are formed.

On the other hand, the ceramide contained in the functional hydrogel composition according to the present invention is a polar lipid extracted from whey of milk with ethanol, and mostly milk ceramide consisting of phospholipids (mainly phosphatidylcholine, phosphatidylethanolamine) and sphingolipids (mainly sphingomyelin). can be Milk ceramide is a food ingredient rich in precursors of ceramide necessary for skin hydration. Milk fat is a dietary source of sphingomyelin, and dietary sphingomyelin increases the level of ceramide in the body, and this ceramide plays a role in maintaining moisture supply of the epidermis and skin barrier function.

The milk ceramide contained in the functional hydrogel composition according to the present invention may be used after ethanol extraction of whey protein separated from milk, followed by filtration, concentration, and drying, and the final raw material consists of 35-40% protein and 30-35% fat. can be In particular, the phospholipid content is 10 to 15%, and the phospholipid may mainly include sphingomyelin, cerebroside, phosphatidylserine, phosphatidylcholine, and the like. In addition, low molecular weight fish collagen can be used by spray-drying hydrolyzate treated with Pangasius fish by enzyme, and by analyzing the amino acid composition and content, the sum of proline and hydroxyproline content is 20-25% of the total amino acids. .

The main role of ceramides in the stratum corneum is the protective function of the epidermal barrier, and when ceramides in the stratum corneum decrease, the skin barrier function is weakened, which causes an increase in water loss between the skin. Milk ceramide is a raw material rich in phospholipids, of which sphingomyelin accounts for 20-25%. Sphingomyelin is a major component of mammalian cell membranes and is also a basic component of the lamellar structure responsible for the barrier function of the skin epidermis. Sphingomyelin contained in milk ceramide extracted from milk has a high content compared to phospholipids derived from other foods. When the absorption rate according to the source of sphingoid, a structural component of sphingomyelin, was evaluated in Caco-2 cells, it was found that the absorption rate of animal-derived sphingoid was higher than that of plant-derived sphingoid. Therefore, sphingomyelin works effectively to strengthen the barrier function of the epidermis of the skin.

Ceramide according to the present invention, in addition to milk ceramide, glucosylceramide may be used, and glucosylceramide in this case is glucosyl containing curcumin, vitamin C, fish collagen, etc. to increase the skin barrier and atopy improvement effect. Ceramides may be used. As a result of measuring the antioxidant activity of the above materials by ABTs and DPPH assay, ABTs assay IC ₅₀ was glucosylceramide 250.77 μg/mL, curcumin 31.41 μg/mL, vitamin C 21.62 μg/mL, DPPH assay IC ₅₀ curcumin 35.46 μg /mL, and the total polyphenol content was also relatively high in curcumin. As a result of MTT assay by culturing RAW 264.7 macrophages and HS68 fibroblasts, the cell viability was 80% at 30 μg/mL of glucosylceramide, 7.5 μg/mL of curcumin, 400 μg/mL of vitamin C, and 1600 μg/mL of fish collagen. As described above, cell proliferation and survival patterns were confirmed. As a result of comparing the NO production inhibitory ability of individual samples and mixed samples, curcumin 7.5 μg/mL is 60% or less, glucosylceramide 15 μg/mL is 70% or less, glucosylceramide 15 μg/mL + curcumin 7.5 μg/mL + vitamin C In the mixed sample of 100 μg/m+fish collagen 1600 μg/mL, it was suppressed to 25% or less, so the mixed sample had a high anti-inflammatory effect. Therefore, it can be confirmed that the antioxidant, anti-inflammatory effect and Collagen I expression promoting effect of the glucosylceramide and curcumin mixture can be confirmed, and it can be confirmed that it can be helpful in the treatment of atopic dermatitis or functional food for improving the skin barrier.

On the other hand, the eye patch 1000 according to the present invention may be a disposable product that is discarded after being used once. These disposable products do not easily rot in their natural state, causing environmental problems. Therefore, in the present specification, we propose an eye patch 1000 made of a plant-derived poly lactic acid (PLA) material that can be biodegradable in a natural state and is not harmful to the human body and the environment.

PLA material is difficult to produce with a low weight (40g/m2) due to its brittle characteristics or its weak tensile strength. have. In order to solve this problem, an amorphous biodegradable PLA eyepatch patch 1000 of 40 g/m 2 or less is produced by passing two pressing rolls to make it non-crystallized while producing at a screw temperature of 230 ° C.

At this time, the embossing rolls among the pressing rolls are at 140°C to 150°C, and the remaining rolls are at 50°C to 60°C. In order to reinforce the strength of the long-fiber PLA fiber spun here, if the temperature of the embossing roll in the pressing roll is below 140℃, the PLA resin does not melt and the tensile strength is weakened. If the temperature of the rest of the general roll is 60℃ or higher, the PLA fiber may be crystallized.

The amorphous PLA eye patch 1000 is produced as described above, but the weight of the eye patch 1000 before the functional hydrogel composition is applied is 20 to 40 g/m 2 , preferably 25 g/m 2 is used. Here, if the weight is 20 g/m 2 or less, it may be a problem when impregnating the functional hydrogel composition, and if it is 40 g/m 2 or more, the adhesion may decrease when attached to the face.

The functional hydrogel composition according to the present invention may further include a biodegradable polymer to solve the environmental problem of the eye patch 1000 discarded after use. In this case, the biodegradable polymer may be polylactide (PLLA: POLY-L-LACTIDE). PLLA promotes collagen production in the body and has anti-wrinkle effects. In addition, PLLA is a biodegradable material that has bioabsorption and organic compatibility, and PLLA is safer because it is completely decomposed into water, carbon dioxide and sugar after collagen production is completed.

On the other hand, loess is rich in minerals and smooths the skin, and loess particles have excellent adsorption power, so it is possible to efficiently remove fats and wastes remaining in the pores of the skin. In addition, the far-infrared rays emitted from loess stimulate the capillaries of the skin and have the effect of promoting blood circulation. This is because loess has a double-layered honeycomb structure, so the higher the SiO ₂ content, the more honeycomb structure. Stimulates it to act as metabolic energy.

However, if only loess is used as a cosmetic agent, it is not suitable for skin lacking nutrients due to its strong cleansing power and extraction action of subcutaneous fat. , even if the bacteria are not completely sterilized, it may adversely affect the skin. Therefore, by combining loess and polylactide (PLLA: POLY-L-LACTIDE), it solves the problem of micro-loess binding to pores.

The functional hydrogel composition according to the present invention may further include a bioadhesive for improving adhesion between the eye patch 1000 and the facial skin, wherein the bioadhesive is a bioadhesive used in ophthalmic military wing surgery. It may be a Beri Plast P Combi Set.

Military wing is a disease in which the fibrovascular tissue of the conjunctiva and Tenon's capsule proliferates and invades the cornea, causing cosmetic problems due to frequent redness, etc. It is a common disease that can cause

Although the military wing can be removed relatively simply with surgical treatment, there is a problem that recurrence is frequent. The cause of the high recurrence is considered to be the activation of subconjunctival fibroblasts, the proliferation of blood vessels, and the accumulation of extracellular matrix proteins due to surgical trauma and post-operative inflammatory response. Therefore, several surgical techniques have been developed to reduce recurrence, and one of them is a technique using the bioadhesive described above. By including the bioadhesive used in the military wing surgery in the functional hydrogel composition, it is possible to prevent adverse effects caused by general adhesives on the skin and at the same time further improve the adhesion between the eye patch 1000 and the facial skin.

In this specification, a "part" includes a unit realized by hardware, a unit realized by software, and a unit realized using both. In addition, one unit may be implemented using two or more hardware, and two or more units may be implemented by one hardware.

The protection scope of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is added once again that the protection scope of the present invention cannot be limited due to obvious changes or substitutions in the technical field to which the present invention pertains.
