Description

TECHNICAL FIELD [0001] The present invention relates to a heating-hydrogel modeling mask and a method of using the same,

Field of the Invention [0002] The present invention relates to a modeling pack and a method of using the modeling pack, and more particularly, to a modeling pack and a method of using the modeling pack, in which beauty oil and essence are added to a heated and melted hydrogel.

Hydrogel is a material in which the wet state can be maintained, and the application fields of wound dressings, contact lenses, medicines or cosmetic agent delivery media, implants, wastewater treatment agents and the like are also diversified. Hydrogel is a three-dimensional hydrophilic polymer network with purified water as a dispersion medium. It has the ability to absorb a large amount of water and has the same flexibility as a natural tissue.

In addition, hydrogels can be added with intelligent release properties that control the delivery of the contained material and new functions such as pH, temperature, electric field, and irritation to the light and swelling or shrinking. Hydrogels with these properties are widely used in the pharmaceutical industry as well as in beauty and biomedical applications because of their structure similar to human cell matrix, inert biocompatibility, elasticity such as rubber, permeability of oxygen and nutrients.

Hydrogels developed for the purpose of wound healing and the like serve to protect the wound from additional trauma, environmental factors that slow down the healing process, or both. It mainly uses polysaccharides, carrageenan and carrageenan gum, which are widely used as binders for the control of carrageenan and carrots black foodstuffs in vegetable gums. .

The hydrogels used in cosmetics and the like are applied to fields of skin care, skin care, skin treatment and the like. It mainly develops branched type gelling polymers and electrolytic polymers to suit the shape of product. This is to allow easy and rapid delivery of the drug to the skin as a hydrogel having high affinity.

In recent years, a mask pack has been developed which is improved in moisturizing, nutritional supply or exfoliation effect by utilizing elasticity, skin adhesion, and soft touch of a hydrogel. Korean Patent Laid-Open Publication No. 2013-0118804 uses a nonwoven fabric or cotton as a base material to keep the shape of the mask pack. Particularly, the nonwoven fabric is widely used as a base material for a mask pack because the fibers are entangled, have. However, as described above, since the nonwoven fabric is produced through a chemical process, skin troubles may occur when the mask pack is used as a base material, and environmental pollution may occur because the nonwoven fabric is not easily decomposed at the time of disposal. The hydrogel often detached from the nonwoven fabric, and there was inconvenience in use. In addition, there is a problem in that the manufacturing cost is increased when the mask is used as the base material of the mask pack. In addition, a mask pack made of a nonwoven fabric or a cotton-based material is easily dried and adheres to the skin.

Accordingly, there is an urgent need to develop a pack which can improve the moisturizing, nutritional supply or exfoliation effect by using the elasticity, skin adhesion, and soft touch of the hydrogel without using a nonwoven fabric or a face for producing a mask pack .

The present invention relates to a modeling pack and a method of using the same.

It is an object of the present invention to provide a modeling pack which can use a warm hydrogel directly as a skin pack without using a nonwoven fabric or a surface using the elasticity, skin adhesion and soft touch of the hydrogel, The present invention relates to a modeling pack capable of maintaining a temperature of 40 占 폚 or more for a predetermined time or more during the solidification process, and a method of using the same.

Another object of the present invention is to provide a modeling pack and a modeling pack which can effectively penetrate into the skin an effective ingredient contained in the hydrogel contained in the hydrogel by directly applying the hydrogel having a temperature similar to body temperature to the skin, And a manufacturing method thereof.

Still another object of the present invention is to provide a modeling pack having excellent adhesion effect even when used on body parts other than face and face, using a hydrogel and a skin adhesive property, ≪ / RTI >

In one embodiment of the present invention, the present invention relates to a packaged pack comprising a hydrogel, wherein the pack pack comprises a molten hydrogel, cosmetic oil and essence.

In one embodiment of the present invention, the hydrogel of the present invention is heated for 20 to 30 seconds at 600 to 700 W for 20 seconds to 30 seconds, or melted by hot water heating at 80 to 100 ° C. As a method for melting a hydrogel, both a method using a microwave oven and a method using a hot water can be used, and the method is not limited to the examples. Most preferably, heating is performed using a microwave oven. The microwave oven generates a high-frequency, high-frequency radio wave from an oscillator called a magnetron, which irradiates an object in the microwave oven. High-frequency, strong radio waves actively move the water molecules contained in an object in the microwave oven to raise the temperature. Further, since the microwave oven includes a turntable, the object can be rotated, and the temperature raising effect can be obtained evenly.

When the hydrogel is heated for less than 20 seconds, there is a problem that the solid hydrogel is insufficiently dissolved. If the hydrogel is heated for more than 30 seconds, the temperature of the hydrogel becomes excessively high, . The time for heating the hydrogel is 20 seconds to 30 seconds, but most preferably 25 seconds for heating the hydrogel.

In one embodiment of the present invention, the wet pack of the present invention is prepared by adding a cosmetic oil and essence to a molten hydrogel and maintaining the mixture at 40 to 60 ° C for 5 to 15 minutes. When the hydrogel is melted using a microwave oven, it can not be directly applied to the skin while maintaining a hot temperature at 70 to 80 ° C. immediately after melting. However, when the hydrogel is mixed with the cosmetic oil and essence, the temperature is 40 to 60 ° C. It goes down and becomes suitable temperature to apply to skin. When the hydrogel is heated in a microwave oven, the temperature rapidly rises. However, when the hydrogel is heated and stored at room temperature after the heating, the temperature of the hydrogel is rapidly lowered, and the hydrogel is simply heated by heating the microwave There is a problem that is difficult to use as a pack. Therefore, it is necessary to maintain a suitable temperature for application to the skin and to maintain the melted state. When the cosmetic oil is added to the melted hydrogel, the temperature drops to 40 to 60 ° C .; however, And the temperature is maintained at 40 to 60 캜. A temperature of 40 to 60 占 폚 will be said to be a temperature range in which the skin feels warm when applied to the skin.

In one embodiment of the present invention, the modeling pack comprises 70 to 80 wt% hydrogel, 15 to 20 wt% essence, and 6 to 15 wt% cosmetic oil. When the hydrogel is contained in an amount of less than 70% by weight, the strength of the gel modeled after application to the skin may be lowered. If the hydrogel is contained in an amount exceeding 80% by weight, gelation may not completely occur in the microwave oven.

In one embodiment of the present invention, the cosmetic oil is selected from the group consisting of isopropyl myristate, ethyl laurate, ethyl myristate, isopropyl palmitate, cyclopentane, cyclooctane, trans-decalin, n-pentane, But are not limited to, decane, tripropylamine, 1,7-octadiene, butyl laurate, cyclododecane, dibutyl ether, isooctane, n-octane, tributylamine, triisobutylamine, polyol esters, triglycerides, diglycerides, Monoglycerides, diglycerides; Caprylic / capric triglyceride, butyleneglycol dicaprylate / dicaprate, triethylhexanone, cetylethylhexanoate, isopropyl myristate, octyldodecanol; Liquid paraffin, Vaseline, Hydrogenated polydecene, Squalene; Micro-stalin wax, beads wax, lanolin wax; Jojoba Oil, Avocado Oil, Almond Oil, Olive Oil, Sesame Oil, Wheat Germ Oil, Four Flower Oil, Camellia Oil, Castor Oil, Grape Seed Oil, Green Tea Seed Oil, Macadamia Nut Oil, Palm Oil, Rosehip Oil, Tree oil, argan tree kernel oil, lavender oil; At least one selected from the group consisting of cyclic dimethicone, cyclomethicone, phenyltrimethicone, cyclopentasiloxane, and dimethicone. It is preferable to use a group consisting of triisobutylamine, polyol ester, triglyceride, diglyceride, monoglyceride, triethylhexanoin, cetylethylhexanoate, isopropyl myristate, cyclopentasiloxane and octyldodecanol And at least one selected from the group consisting of avocado oil, almond oil, camellia oil, castor oil, grape seed oil, green tea seed oil and macadamia nut oil, more preferably at least one selected from the group consisting of cetyl ethyl Hexanoate, cyclopentasiloxane, and grape seed oil. By using cosmetic oil, the temperature of the hydrogel in which the temperature is raised can be prevented from dropping rapidly, and it can be used as a pack to be applied.

The modeling pack according to an embodiment of the present invention includes a hydrogel, a cosmetic oil, and an essence. In addition, the modeling pack may contain necessary components according to applications. For example, for use in patients with atopic dermatitis, green tea that is effective for atopic skin can be used. That is, in addition to the essential components, hydrogel cosmetic oils and essences, in addition to being a modeling pack to be applied, it may further contain skin-effective ingredients. Generally, in the case of a pack using a nonwoven fabric or a cotton, there is a problem that the use of the nonwoven fabric or the cotton is limited depending on the shape of the nonwoven fabric or the cotton, and there is a problem that it tends to fall easily due to adhesion to the skin and adhesion to the nonwoven fabric or cotton. The modeling pack according to the example is a pack applied in a molten state of the hydrogel. When the pack is hardened after it is packed, it hardens according to the shape of the skin. Since the hydrogel has high adherence to the skin, It is possible to have a high adhesive force.

An embodiment of the present invention comprises: 1) heating a hydrogel for 20 to 30 seconds; 2) adding essence and cosmetic oil to the hydrogel dissolved by the heating step of step 1); 3) mixing the mixture of step 2); And 4) a method of using the modeling pack to apply the mixed mixture of step 3) to a desired skin area. In order to use the modeling pack, the hydrogel stored in a polymer vinyl pack such as a retort pouch is heated for 20 to 30 seconds, the hydrogel dissolved in the retort pouch is transferred to a storage container such as a paper cup, and essence and cosmetic oil are added . After mixing the essence with the cosmetic oil, apply it to the body part where you want to use the pack. When the hydrogel is heated at room temperature, the hydrogel generally maintains a solid state. When the hydrogel is heated, it becomes a high-temperature molten hydrogel. In order to use the hydrogel as a pack, a molten hydrogel is used. However, when heat is applied to dissolve the solid hydrogel, the temperature rises rapidly, and when the heat supply is interrupted, it is difficult to use the pack in which the temperature is rapidly lowered. To solve this problem, essence and cosmetic oil are added to the molten hydrogel. When the cosmetic oil is added to the hydrogel, the cooling rate of the hydrogel is drastically reduced as compared with the case where the cooling rate of the hydrogel is not added, so that the temperature range of 40 to 50 ° C is maintained for a certain period of time.

In one embodiment of the present invention, the heating step in step 1) is a method of using a modeling pack in which the heating step in step 1) is heated at 600 to 700 W for 20 to 30 seconds or heated at 80 to 100 DEG C . As a method for heating the hydrogel, both a method using a microwave oven and a method using a hot water bath can be used, and the method is not limited to the examples. Most preferably, heating is performed using a microwave oven.

In an embodiment of the present invention, the modeling pack may be maintained at 40 to 60 캜 for 5 to 15 minutes after completion of the agitation step by adding essence and cosmetic oil of steps 2) and 3). When the hydrogel is melted using a microwave oven, it can not be directly applied to the skin while maintaining a hot temperature at 70 to 80 ° C. immediately after melting. However, when the hydrogel is mixed with the cosmetic oil and essence, the temperature is 40 to 60 ° C. It goes down and becomes suitable temperature to apply to skin. When the hydrogel is heated in a microwave oven, the temperature rapidly rises. However, when the hydrogel is heated and stored at room temperature after the heating, the temperature of the hydrogel is rapidly lowered, and the hydrogel is simply heated by heating the microwave There is a problem that is difficult to use as a pack. Therefore, it is necessary to keep the temperature suitable for application to the skin and maintain the melted state. When the cosmetic oil and the essence are added to the melted hydrogel, the temperature drops to 40 to 60 ° C, And the temperature of 40 to 60 DEG C is maintained. A temperature of 40 to 60 占 폚 will be said to be a temperature range in which the skin feels warm when applied to the skin. The temperature range of 40 to 60 ° C is the temperature range in which you feel warm when you use a pack, which is the optimal temperature range for skin-effective ingredients contained in the modeling pack to be easily delivered to the skin. That is, when the temperature is lowered to less than 30 ° C, the delivery of the active ingredient is not easy due to the difference in body temperature and temperature, and the hydrogel is hardened. If the temperature is higher than 60 ° C, the temperature is too high to be applied to the skin.

The present invention relates to a modeling pack to be applied and a method of using the same, and a warm hydrogel can be directly applied to the skin as a pack without using a nonwoven fabric or a surface using the elasticity, skin adhesion and soft touch of the hydrogel. When the heated hydrogel maintains a temperature similar to the body temperature and the hydrogel is directly applied to the skin, the active ingredient contained in the hydrogel contained in the skin can easily penetrate into the skin, which is advantageous for delivery of the active ingredient. In addition, the molten hydrogel is excellent in adhesion to the skin. Due to such properties, the hydrogel has excellent adhesion effect even when used on body parts other than the face and the face.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood that both the foregoing description and the following detailed description are exemplary, explanatory and are intended to be illustrative, and not restrictive. The scope of the invention is defined by the appended claims rather than by the foregoing description. will be.

Referring to FIG. 1, a method of using a modeling pack according to an embodiment of the present invention includes: 1) heating a hydrogel for 20 to 30 seconds (S100); 2) adding (S200) essence and cosmetic oil to the molten hydrogel by the heating step of step 1); 3) mixing the mixture of step 2) (S300); And 4) a method of using a modeling pack to apply the mixed mixture of step 3) to a desired skin area (S400). More specifically, in step (1), the hydrogel stored in the retort pouch is heated in the microwave oven for 20 seconds to 30 seconds as it is, and the molten hydrogel is introduced into a storage container such as a paper cup. The molten hydrogel is maintained at a high temperature, but when stored at room temperature due to the nature of the hydrogel, the temperature suddenly drops and becomes a hardened hydrogel again. In order to prevent a sudden temperature drop of the hydrogel, 2) add essence and cosmetic oil of step S200. The essence is to deliver the active ingredient to the skin, and the cosmetic oil is to prevent a sudden temperature drop of the hydrogel.

Likewise, the modeling packs of Production Examples 2 to 3 were measured at 55 ° C and 59.5 ° C after 5 minutes but at 50 ° C even after 10 minutes, The temperature was slightly higher than body temperature. That is, in the case of the modeling packs of Production Examples 1 to 3, the packs were continuously packed on the skin to maintain a temperature at which a warm feeling could be obtained. However, as in Comparative Example 1, in the case of an oil-immersed modeling pack, it was measured at 50 占 폚 at 5 minutes, 30 占 폚 at 10 minutes, and 15 占 폚 after 20 minutes, It was confirmed that the usable time before hardening was shorter than that of 1 to 3. As can be seen from Comparative Examples 5, 6, and 7, when the grape seed oil, cetyl ethylhexanoate or cyclopentasiloxane was mixed and used alone (Production Examples 1 to 3), the use time of the modeling pack Which is more advantageous in the case of the present invention.

[ Example  3]

modelling  Comparison of use of packs

The packs prepared according to Preparation Example 1 and Comparative Example 4 were subjected to a performance test on five men and women. The pack prepared according to Preparation Example 1 and Comparative Example 4 was applied to the face, and skin irritation, Were evaluated according to the following evaluation criteria, and the results are shown in Table 2 below.

Evaluation items Production Example 1 Comparative Example 4 Skin irritation 4.00 4.00 Moisture power 3.86 3.78 Adhesion 3.52 3.10 Product Satisfaction 3.72 3.36 (Evaluation criteria: 0 ~ 5, high score when there is no stimulation)

The modeling pack prepared in Preparation Example 1 showed a high score of 4.00 in skin irritation, a moisture resistance of 3.86, and a stickiness of 3.52. On the other hand, in Comparative Example 4 in the form of a mask pack sold on the market, skin irritation was 4.0, moisture resistance was 3.78, and adhesion was 3.1.

As a result, the modeling pack of Production Example 1 was rated better than Comparative Example 4, which was manufactured from a mask pack in terms of skin irritation, moisturizing power and adhesion. This means that the same mask pack as that of Comparative Example 4 is used at room temperature or in a cold state, and a pack having a low temperature does not effectively transmit the effective ingredients of the pack to the skin. As a result, I will say that you have been evaluated. In addition, when the hydrogel is coated with a hydrogel as in Comparative Example 4, the adhesion of the hydrogel to the skin is considered to be lower than that of the pack in which the hydrogel itself is applied to the skin.
