Description

Heated material structure

The present invention relates to a heat-cured material structure, in particular, a thin heat-generating body and a semi-solid gel layer, and the semi-solid gel layer is coated with a heat-producing structure of a skin external preparation having a concentration gradient.

In general, the dressing can be classified into a wet dressing and a dry dressing. Common wet dressings have masks. Most of the main structures are only using a single layer of supporting fabric (for example, non-woven fabric), and "soaking" skin external preparations (such as hyaluronic acid, collagen, etc.), users can directly apply a single layer of fabric. Stick to the face; the more common dry dressings have external patches, which are directly applied to the supporting fabric to "coat" the skin external preparation, and coated with an adhesive layer so that the patch can be firmly adhered to the target site. on.

However, regardless of the conventional wet dressing soaking skin external preparations (such as hyaluronic acid, collagen, etc.) or dry application materials for skin external preparation, the distribution of liquid or gel-like skin external preparation on the dressing material cannot be achieved. The problem of expected concentration. In detail, the wet dressing is directly infiltrated with the external preparation for skin, so that the whole material of the dressing material has a uniform concentration of the skin external preparation, and when applied to the skin, only the external skin preparation for the skin can be absorbed by the skin. Further, the skin external preparation adsorbed inside the dressing (for example, non-woven fabric) is wasted because it cannot be absorbed. On the other hand, the dry application material applies the external preparation for skin to the surface of the application material, and theoretically, the surface concentration of the application is the highest, but in fact, the external preparation for skin gradually penetrates into the application material as the storage time is longer. Internally, the final overall concentration is evenly distributed throughout the dressing. As a result, the concentration of the skin external preparation on the surface of the dressing is inevitably lowered, which is inferior to the desired concentration of the externally applied agent, and the initial coating cannot be maintained. After the concentration is set, and it is easy to cause waste of external preparation for skin. Further, in the subsequent use of the dry dressing, since the skin cannot be absorbed by contact with the skin external preparation of a desired concentration, the effect of the external preparation for the skin is not problematic.

Further, in general, when a dressing material is used, the temperature of the enclosed space between the dressing material and the skin portion can be increased to achieve the effect of the local skin absorbing the external preparation for the skin. As a description of the wet dressing such as the mask, when the user applies the mask to the face, the skin can theoretically be separated from the outside air by the application of the film, so that a space is formed between the skin and the mask, when the space is When the body temperature is slightly heated, the surface temperature of the skin will increase (about 1 °C only), the capillary pores open due to the heat temperature and the microvasculature expands. At this time, the skin external preparation on the mask can be absorbed into the skin cortex through the percutaneous absorption, increasing the skin pair. The absorption of the external preparation for skin. In the conventional medical field, the principle of percutaneous absorption of a wet dressing mask can also be applied to patients with dermatological diseases, such as closed therapy for patients with dry or chronic eczema skin diseases, because the stratum corneum of the lesion is too thick, Therefore, after rubbing the affected part, the affected part is covered with plastic wrap or waterproof and airtight plastic to increase the temperature of the local skin, thus increasing the absorption rate of the affected part of the skin.

However, there is still room for improvement in wet-laid masks. The wet-laid mask uses only a single layer of cloth to infiltrate the skin external preparation. However, during use, the hot air in the micro-space formed between the mask and the skin is easily disturbed by the external environment temperature, and it is difficult to maintain the desired temperature. As a result, the wet dressing mask does not allow the skin external preparation to be effectively absorbed by the skin. In addition, skin external preparations (mostly liquid or gel-like) are relatively cold due to the specific heat relationship in a low temperature (such as winter) environment, which increases the discomfort in use.

On the other hand, there is still room for improvement in conventional dry dressings. Taking a sore patch as an example, a conventional sore patch adheres to the skin of the user and penetrates the tight micro-environment between the skin and the patch, so that the specific component of the pain relief and inflammation can produce a warm feeling to the affected part. However, these warm feelings will gradually disappear with the oxidation or percutaneous absorption of the anti-inflammatory and analgesic chemical components, and the heat cannot be sustained for a certain period of time.

Although there is a heat-generating thermal eye mask at present, the heat-applied eye mask has only a simple heat-generating structure, and can only provide a heat-applying effect.

In the technique of improving the structure of the dressing material to achieve the best heat transdermal absorption effect, there is a skin care heating device disclosed in the prior art, such as the Republic of China new patent TW M489550, which is separately placed in a compartment with a heat pack and a skin care film unit. In the bag body, the skin care film unit can be heated by the heat pack before using the skin care film unit. However, since the heat pack can only heat the skin care film unit before use, when the skin care film unit is removed from the bag body, it will easily lose heat, so that the skin heat treatment unit can not be used while achieving the continuous heat application effect, and the heat application effect is not good.

Therefore, in order to improve the aforementioned deficiency, the object of the present invention is to provide a heat-cured material structure in which a skin external preparation is concentrated on the surface of a semi-solid gel layer and can be applied while being applied to the skin. In order to achieve the above object, the present invention provides a heat-cured material structure comprising a semi-solid gel layer combined with a skin external preparation having a concentration gradient, which is applied to the skin while raising a temperature to promote the skin through a stable heat generating body.

This creation provides an embodiment which is a heat-fed construction. The structure of the heat-generating material of this embodiment can be understood by referring to Fig. 1 of the drawings. Fig. 1 is a schematic view showing the structure of a heat-generating material according to an embodiment of the present invention. The heat-generating material structure 10 includes a thin heat generating body 110 and a semi-solid gel layer 120. The thin heating element 110 may have a thickness of 0.1 to 5 mm, and the semi-solid gel layer 120 may have a thickness of 0.1 mm to 3 mm. The thin heating element 110 is bonded to one side of the semi-solid gel layer 120, wherein the semi-solid gel layer 120 is coated with a skin external preparation 125 having a first concentration and a second concentration.

The thin heating element 110 of the embodiment of the present invention is mainly composed of iron powder, salt, activated carbon, water retaining agent, vermiculite and water. Further, the thin heating element 110 includes a packaging material, which may be a non-woven fabric. The heat generating component is encapsulated in a packaging material to form a thin heat generating body 110 having a thickness of less than 5 mm. In detail, the thickness of the thin heating element 110 can be controlled within 0.1 mm to 5 mm, preferably 0.1 mm to 3 mm. In use, the heat generating temperature of the thin heating element 110 is from 28 ° C to 45 ° C, preferably a temperature similar to that of human skin, such as 35 ° C to 45 ° C.

The semi-solid gel layer 120 of the presently described embodiment contains solids and water. The solid matter is selected from the group consisting of polyacrylic acid, polyol, polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), combinations thereof, copolymers thereof, or combinations thereof (for example, polyphenylacetic acid acrylic copolymer). Group of hydrophilic polymer materials. And the molecular weight of the hydrophilic polymer materials is greater than 1×10 ⁵ . The solids of the semi-solid gel layer may range from 1% to 70%, preferably from 3% to 30%, by total weight of the semi-solid gel layer. The semi-solid gel layer may have a thickness of 0.1 mm to 3 mm. When the semi-solid gel layer 120 is formed of a hydrophilic polymer material, the semi-solid gel layer 120 may contain a relatively high water content. For example, the semi-solid gel layer 120 may have a water content of 30% to 99. %, preferably a water content of 50% to 95%. The semi-solid gel layer 120 is coated with the skin external preparation 125, and the skin external preparation 125 may be in a ratio of 1% to 5% by weight based on the total semi-solid gel layer.

In detail, the semi-solid gel layer 120 of the present invention is composed of a solid material of a hydrophilic polymer material and water. When the skin external preparation 125 is applied to the surface of the semi-solid gel layer 120, the chemical molecules of the skin external preparation 125 are attracted by the intermolecular positive and negative charges, and the hydrophilicity of the semi-solid gel layer 120 is concentrated. In the molecular polymer. Thus, the concentration of the external preparation for skin 125 can be the highest concentration near the surface layer of the semi-solid gel layer 120, and only a small portion of the external preparation for skin 125 diffuses to the depth of the semi-solid gel layer 120, so that a concentration gradient is formed. phenomenon.

According to the above-described arrangement of the semi-solid gel layer 120 of the present invention, the skin external preparation 125 coated on the heat-applied structure of the present invention can exhibit a concentration gradient. In detail, the concentration of the external preparation for skin 125 can be divided into three to six concentration intervals.

The following three concentration intervals are used as an explanation. The first section described in the embodiment of the present invention means that the semi-solid gel layer 120 does not adhere to one side (ie, the surface) of the thin heating element 110; the second section refers to the semi-solid gel layer 120 from the surface to the surface. A depth of 50% of the direction in which one side of the thin heating element 110 is attached (downward); the third section is a section from the depth of 50% to a depth of 100% of the semi-solid gel layer 120. The concentration of the external preparation for skin 125 has different concentrations in the first section, the second section, and the third section, respectively. The concentration of the skin external preparation 125 in the first section is the concentration closest to the initial coating, and thus the concentration in the first section is the highest. Here, the concentration of the skin external preparation 125 in the first section is defined as 100%, and the concentration of the skin external preparation 125 in the second section is 40 to 100%; and the concentration of the external preparation 125 of the skin in the third interval is less than 40. %. In short, the concentration of the external preparation for skin 125 is the highest on the surface of the semi-solid gel layer 120, and the external preparation for skin is present at a low concentration of 50% or less of the depth of the semi-solid gel layer 120, and the external preparation for skin The difference between the concentration in the first interval and the concentration in the third interval may be greater than 60%.

Similarly, according to the heat-generating dressing structure of one embodiment of the present creation, the distribution of the concentration gradient of the other skin external preparation 125 is also exhibited. In this distribution, the concentration of the external preparation for skin 125 is divided into six concentration intervals, and reference is made to Fig. 2, which is a graph showing the relationship between the depth of the semi-solid gel layer and the concentration of the external preparation for skin. Here, the surface of the semi-solid gel layer 120 is defined as a first interval, and the concentration of the skin external agent 125 in the interval is closest to the initial coating concentration, which is 100% of the concentration; the second interval is a semi-solid gel layer. 120 extends from the surface to the semi-solid gel layer 125 by a depth of 10% with respect to the surface, the concentration of the skin external preparation 125 in the interval is ≥90% and <100%; the third interval is the semi-solid gel layer 120 from the depth From 10% to 35% of the depth, the concentration of the skin external preparation 125 in the interval is 70% to 90%; the fourth interval is the depth of the semi-solid gel layer 120 from 30% to 50%, and the interval has skin external application. The concentration of the agent 125 is 35% to 70%; the fifth interval means the depth of the semi-solid gel layer 120 from 50 to 80%, and the interval includes the skin external preparation 125 of 10% to 35%; the sixth interval is Refers to the semi-solid gel layer 120 from below 80% depth, which contains less than 10% concentration of the skin external preparation 125. As can be seen from Fig. 2, the concentration of the external preparation for skin 125 is the highest on the surface of the semi-solid gel layer 120, and the external preparation for skin is present at a low concentration of the semi-solid gel layer 120 at a depth of 80% to 100%. The difference between the highest concentration and the lowest concentration of the external preparation for skin may be greater than 90%.

Examples of the external preparation for skin may be a moisturizer, a whitening agent, a percutaneous absorption medicine, etc., but are not limited thereto.

According to an embodiment of the present creation, an exemplary embodiment is provided herein as follows. The technical field of the present invention belongs to those skilled in the art, and the technical content of the present creation can be understood more easily and easily by referring to the schema.

The present invention provides a first embodiment which is an embodiment in which a dry-laid mask is formed using the heat-applied material structure of the embodiment of the present invention.

Please refer to FIG. 4, which is a schematic view of the dry-faced mask of the first embodiment of the present invention. The first embodiment provides a dry-type mask 30, which is a thin heat generating body 310, a first adhesive layer 320, a first supporting layer 330, and a semi-solid from the outermost surface of the mask to the surface in contact with the face. Gel layer 340.

In this embodiment, the thin heat generating body 310 mainly contains a heat generating component composed of iron powder, salt, activated carbon, water retaining agent, vermiculite and water. The proportion of these ingredients is iron powder: salt: activated carbon: water retention agent: vermiculite: water = 6: 1.2:1:1:1:3. However, the ratio is merely illustrative and may not be limited thereto. Further, the thin heating element 310 includes a packaging material, which may be a non-woven fabric. The aforementioned heat generating component is encapsulated in a packaging material by a technique known to those skilled in the art. In the present embodiment, the thickness of the thin heating element 310 is 0.26 mm.

Further, the first adhesive layer 320 is mainly used to bond one surface of the thin heating element 310 to one surface of the first support layer 330. As described in one embodiment of the present invention, the first adhesive layer 320 may include a chemical fiber layer (for example, an interlayer of a waterproof gas-permeable film formed of a polytetrafluoroethylene material), an adhesive such as polyurethane or acrylic, or a combination thereof. In the present embodiment, the first adhesive layer 320 comprises a chemical fiber layer and a polyurethane (PUR) adhesive. The chemical fiber layer is provided on one side of the thin heating element 310, and the thin heating element 310 is bonded and fixed to the chemical fiber layer through a urethane adhesive. In this embodiment, the thickness of the first adhesive layer 320 is 0.03 mm.

In this embodiment, the first support layer 330 is used to support the overall dry-laid mask, and the first support layer is a chemical fiber material or a natural fiber material. As mentioned above, chemical fiber materials include, but are not limited to, non-woven fabrics, polyesters, nylons, and the like; natural fiber materials include, but are not limited to, wood pulp, cotton, hemp, silk, bio-fibers, and the like. In the dry-type mask of this embodiment, the first support layer 330 is a non-woven material, and the first support layer 330 has a thickness of 0.1 mm. The first support layer 330 serves as a main structure and is mainly used to maintain the shape and stability of the dry-laid mask 30.

Further, the semi-solid gel layer 340 comprises a solid material and water. According to an embodiment of the present invention, the solid material is formed of a hydrophilic polymer composite material, which may be a polyacrylic acid type, a polyhydric alcohol type, or a polyvinyl alcohol type (PVA). And polyvinylpyrrolidone (PVP), a composition thereof, a copolymer thereof or a combination thereof (for example, a polyphenylacetic acid acrylic copolymer), and the hydrophilic polymer materials have a molecular weight of more than 1 × 10 ⁵ . In this embodiment, the semi-solid gel layer 340 has a thickness of 2 mm.

Further, the surface of the semi-solid gel layer 340 is coated with a skin external preparation 325. When the skin external preparation 325 is contained in the semi-solid gel layer 340, the active ingredients of the skin external preparation 325, for example, moisturizing whitening and the like, can be infiltrated into the semi-solid gel layer 340 by chemical intermolecular force. And is locked in the polymer. In addition, the positive and negative charges of the material passing through the semi-solid gel layer 340, and the high molecular weight of the polymers, allow the skin external preparation 325 to be concentrated on the semi-solid gel layer when applied to the semi-solid gel layer 340. The surface layer 340 is such that the concentration of the skin external preparation 325 on the surface of the semi-solid gel layer 340 is close to the concentration of the initially applied initial skin external preparation 325, and only a small portion of the skin external preparation 325 gradually goes to the semi-solid gel. The bottom layer of layer 340 is decremented to form a concentration gradient. In the embodiment of the dry-type mask 30, the external preparation for skin is mainly a moisturizing ingredient.

In this embodiment, the solid matter of the semi-solid gel layer comprises the following material: sodium polyacrylate, having a molecular weight of about 4×10 ⁶ , and accounting for 1.5% by weight of the semi-solid gel layer; Pyrrolidone, molecular weight 3 × 10 ⁶ , accounting for 0.5% by weight of the semi-solid gel layer; Tween 80 (polyoxyethylene (20) - sorbitan monooleate), accounting for semi-solid condensation The total weight percentage of the rubber layer is 3%. The skin moisturizing ingredient contains hyaluronic acid (molecular weight 1×10 ⁵ ), which accounts for 1% of the total weight of the semi-solid gel layer; macromolecular hyaluronic acid (molecular weight: 1×10 ⁶ ), which accounts for the total weight of the semi-solid gel layer. Percentage 1%; glycerin, 0.5% by weight of the total weight of the semi-solid gel layer; amino acids, 1.5% by weight of the semi-solid gel layer; propylene glycol, based on the total weight of the semi-solid gel layer, 1 %. The water content of the semi-solid gel layer 340 was 90%.

Actually, the concentration of the moisturizing component of the present invention in the semi-solid gel layer 340 of the dry-type mask 30 was tested by an infrared spectrum analyzer, and it was found that the semi-solid gel layer 340 of the dry-laid mask 30 of the present invention contained five. The concentration range of the moisturizing ingredients. If the moisture content of the surface of the semi-solid gel layer 340 (away from the surface of the thin heating element) is 100%, the concentration of the semi-solid gel layer 340 at a depth of 0.5 mm from the surface is 64.5%; the concentration of the semi-solid gel layer 340 at a depth of 1 mm from the surface is 62.2%; the concentration of the semi-solid gel layer 340 at a depth of 1.5 mm from the surface is 48.9%. The concentration of the semi-solid gel layer 340 having a depth of 2 mm from the surface was 20.6%.

In particular, in this embodiment, the polyvinylpyrrolidone dissociates into a positively charged pyrrolidone group in water, while the semi-solid gel layer carries a negatively charged acrylic functional group. Therefore, when a moisturizing component such as hyaluronic acid as a skin external preparation is applied to the semi-solid gel layer, the chemical molecules are attracted by the negative charge on the surface of the semi-solid gel layer, but are subjected to the polyvinylpyrrolidone polymer. Molecular effects, moisturizing ingredients such as hyaluronic acid are concentrated on the surface layer of the semi-solid gel layer. As a result, the surface of the semi-solid gel layer will maintain the highest concentration of moisturizing ingredients, and only a small portion of the moisturizing ingredients penetrate deep into the semi-solid gel layer (see Figure 5). The distribution effect of the concentration gradient as described above.

Further, when the dry-type mask 30 of the first embodiment of the present invention is used, the mask is taken out from the package body and simply smashed, so that the thin heat generating body 310 starts to release heat energy and is conducted to the semi-solid gel layer 340. The heat generation temperature of the thin heating element 310 is 45 ° C, and the surface of the semi-solid gel layer 340 away from the surface of the thin heating element 310 is attached to the skin of the face, and the temperature of the surface of the semi-solid gel layer 340 is actually measured. High temperature, about 37 to 41 ° C. The dry-type mask 30 can maintain the temperature for a certain period of time, for example, for about 45 minutes to 1 hour, in addition to being able to be heated by the thin heating element 310 to a temperature suitable for direct contact with the skin.

When the semi-solid gel layer 340 is heated by the thin heating element 310 of the dry-type mask 30, the temperature of the entire mask rises, so that the temperature of the skin in contact with the mask rises, so that the pores of the skin are opened, and the efficiency of percutaneous absorption is increased. In addition, since the moisturizing component contained in the semi-solid gel layer 340 is distributed in the entire gel layer with a concentration gradient, and the surface of the semi-solid gel layer has the highest moisturizing component, the user's skin is also protected. Absorption efficiency of wet components. In order to further understand the moisturizing effect of the dry-face mask 30 of the present invention, the creator attached the dry-face mask of the first embodiment of the present invention to the subject (three) skin for 15 minutes, and removed the mask and utilized it. The skin tester measures the moisturization of the skin. After application of the dry-face mask, the average skin moisturization of the three subjects was 57.3%. Further, the moisturizing effect of the dry-laid mask of the present invention is compared with the conventional commercially available wet-coated mask product. Take four commercially available wet-coated mask products, namely Desheng Pharmaceutical Co., Ltd.: Crystal Jelly Mask; Morita Cosmeceutical: Hyaluronic Acid Complex Liquid Mask; St. Clair: Hyaluronic Acid 100% Moisturizing Mask; and LADY MARIAN Beauty: White pearl whitening mask. The masks were applied to the skin for 15 minutes at the same time on different days. Skin hydration after using a commercially available facial mask product is approximately 37% to 55%. Compared with the dry-faced mask of the embodiment of the present invention, it was found that the dry-type mask of the first embodiment of the present invention can provide a skin with a high degree of moisturization (over 57%).

In summary, the dry-type mask provided by the first embodiment of the present invention combines the structure of a thin heating element and a semi-solid gel layer, and the surface layer of the semi-solid gel layer has the highest concentration of moisturizing component. When applied with a dry-faced mask, the skin can be directly exposed to the highest concentration of moisturizing ingredients, which is beneficial to the skin's complete absorption of the moisturizing ingredients. In addition, by heating the dry-faced mask, the temperature of the skin surface rises, and the microvascular microcirculation of the skin is increased, thereby accelerating the metabolism rate in the skin and increasing the oxygen content of the skin. The dry-coated mask provided by this creation can provide a slightly higher temperature (37 to 41 ° C) than the human body temperature. This warming effect can also open the pores and increase the absorption efficiency of the skin on the external preparation of the skin.

According to an embodiment of the present invention, a second embodiment is provided herein which is an embodiment in which a heated sore patch is formed using the heat-applied material structure of the embodiment of the present invention.

In the second embodiment of the present invention, please refer to FIG. 6 , which is a schematic diagram of the heated sore patch of the second embodiment of the present invention. The second embodiment provides a heating and sore patch 40, wherein the structure from the outermost surface of the patch to the surface in contact with the skin is the second supporting layer 432, the second adhesive layer 422, the thin heating element 410, and the first The adhesive layer 420, the first support layer 430, and the semi-solid gel layer 440.

In this embodiment, the material of the thin heating element 410 is the same as that of the first embodiment. It mainly contains iron powder, salt, activated carbon, water retention agent, vermiculite and water.
