The characteristics of the main components constituting the patch for lengthening eyelashes prepared as described above will be described as follows.

- next -

1) Polyacrylic acid: A polymer of acrylic acid, which can be used instead of a carbomer. It is mainly used for mask packs because it is used as an emulsifying agent, emulsifying agent and bonding property. Polyacrylic acid exists in the form of powder and is made into aqueous solution (about 25%) in water to make polyacrylic acid liquid, which is used as a raw material for cosmetic ingredients. It also dissolves in water and is a hydrophilic component and is used as an aqueous thickener.

2) Sodium hydroxide: It is also called sodium hydroxide (NaOH). It is a representative strong base and has deliquescence which absorbs water vapor in the air and melts by itself. In addition, sodium hydroxide absorbs carbon dioxide (CO ₂ ), which, because it melts in water to some extent, can absorb carbon dioxide both in the solid state and in the aqueous state. On the other hand, sodium hydroxide that absorbs carbon dioxide turns into sodium carbonate.

3) Glycerin: It is a component contained in the fat of plants and animals. It is highly viscous, has wettability and unique dissolving power, and is used as viscosifier, moisturizer, booster and solvent.

4) Titanium oxide: Ultraviolet scattering agent, a minerals component refined from the mineral called brookite. In addition, it is a component that blocks both UVA and UVB, and is also a less irritating ingredient that can be used for contact dermatitis.

5) Agar: Agar is a viscous complex polysaccharide mixture extracted by physical and chemical treatments with seaweed as a main raw material. It cleanses the blood of a cold person and normalizes hormone secretion.

6) sodium polyacrylate: It is sodium salt of acrylic acid polymeric material and is mainly used as emulsifying stabilizer, viscosity increasing agent (aqueous), film forming agent, skin conditioner (softener) and absorbent.

7) TOCOPHERYLATE ACETATE: It is a fat-soluble compound. It is also called vitamin E acetate. It is mainly used as raw material for skin-related products such as skin cream. It is known to protect skin from harmful oxygen. It is used as an alternative to pure tocopherol and has antioxidative effects such as inhibiting the oxidation of unsaturated fatty acids constituting the cell membrane.

8) Jojoba oil: Jojoba oil is a liquid ester oil obtained from seeds of jojoba, which is superior in terms of stability and feel, and is widely used as an oil-based raw material mainly in basic cosmetics. The jojoba oil has a less oily sensation than other vegetable oils and has a structure of wax ester which is a component of sebum, so it is easy to be familiar with the skin. Therefore, it is used as an oil component in make-up products such as skin care products such as emulsion, cream, body oil, hand lotion, lipstick and foundation.

9) Polysorbate 60: A nonionic surfactant obtained by addition of ethylene oxide to free hydroxyl groups of mainly sorbitan stearate. It is used to uniformly disperse liquids and solids which are not mixed well with each other. And is used as an emulsifier and a stabilizer.

10) Mineral oil: Also called mineral oil, it is a mixture of hydrocarbons in liquid state obtained by refining crude oil. It is mainly used as a solvent, a flavoring agent, a skin care agent, a skin conditioner (a moisture barrier agent, a softener) and the like.

11) Adenosine: A nucleotide, which is a combination of adenine and D-ribose, and ribonucleic acid (RNA) or ATP. It is present in cells of all organisms such as animals and plants, It works as a component of human cells. It penetrates into the skin. It has excellent stability and durability. It has the anti-inflammatory function and it is very effective for the improvement of oily skin troubles such as acne.

12) VP / dimethylaminoethyl methacrylate copolymer: A polymer obtained from vinylpyrrolidone and dimethyaminoethyl methacrylate monomer, which is mainly a binder, a film former, a suspending agent - Non-surfactant and the like.

13) Phenoxyethanol: slightly soluble in water and easily soluble in ethanol and ether. It is produced industrially by the reaction of ethylene oxide with phenol in an alkaline solution and is used for organic synthesis and fragrance.

14) sodium hyaluronate: This is a sodium salt of hyaluronic acid extracted from a chicken egg plant. It is a kind of mucopolysaccharide and has a water content of about 6,000 times as much as that of water, It is a natural moisturizing factor. It also prevents deep penetration of external stimuli and germs from the skin and prevents skin troubles by eliminating bacteria.

15) Aluminum glycinate: One of the compositions of hydrogels commonly used for mask packs and patches, is a kind of metal salt. It is mainly used as a pH adjusting agent, a buffer, and the like.

Hereinafter, a method of manufacturing a patch for widening eyelash extension having the wrinkle-reducing function including the above-described components will be described separately in each step.

Ⓐ step

The step (a) of the present invention comprises the steps of maintaining 65.0 - 80.0% by weight of polyacrylic acid, 15.0 - 20.0% by weight of purified water and 5.0-15.0% by weight of sodium hydroxide, Into a production tank and stirring them to form a first agitated product,

65.0 wt.% To 80.0 wt.% Of polyacrylic acid, 15.0 to 20.0 wt.% Of purified water and 5.0 wt.% To 15.0 wt.% Of sodium hydroxide were put into a production tank maintained at a constant temperature of 80 to 85 ° C., Water is formed, and the production tank in the above step may be further stirred with the first agitated product by adding the agitated product to be described later.

The polyacrylic acid acts as a thickening agent and is preferably added in an amount of 65.0 wt% to 80.0 wt% with respect to the total composition ratio. When the polyacrylic acid is added in an amount of more than 80.0% by weight, the tackiness is increased but the stirring is not smooth due to the high tackiness. When the content is less than 65.0% by weight, the tackiness is lowered, It may not be.

The purified water is a substance which smoothes the stirring with polyacrylic acid and sodium hydroxide, and it is preferable that 15.0 wt% to 20.0 wt% is added to the total composition ratio. When the purified water is added in an amount of more than 20.0 wt%, the shape of the agitated material to be stirred is discarded. When the amount of the agitated material is less than 15.0 wt%, solidification of the agitated material is progressed, It becomes difficult to stir.

On the other hand, the sodium hydroxide is preferably a deliquescent component and is preferably added in an amount of 5.0% by weight to 15.0% by weight based on the total composition ratio. When the sodium hydroxide is added in an amount exceeding 15.0% by weight, the strength and hardness of the agitated product may be lowered due to increased deliquescence. If the sodium hydroxide is added in an amount of less than 5.0% by weight, the physical properties of the agitated product become harder, Stirring with a stirring product becomes difficult.

The above components are stirred in a production tank to form a first stirred product wherein the temperature of the production tank is preferably maintained at a constant temperature of between 80 and 85 ° C, The viscosity of the first agitator becomes too weak and the viscosity of the first agitator becomes too high if the components are stirred below 80 ° C.

Ⓑ Step

The step (b) of the present invention is a method of mixing and stirring glycerin 9.0 - 34.0 wt%, purified water 5.0 - 16.0 wt%, titanium dioxide 1.0 - 5.0 wt%, and polyacrylic acid 60 - 70 wt% To form a second agitated material,

A second agitated material is formed by stirring 9.0 to 34.0% by weight of glycerin, 5.0 to 16.0% by weight of purified water, 1.0 to 5.0% by weight of titanium dioxide and 60 to 70% by weight of polyacrylic acid.

The glycerin is highly viscous and exhibits wettability and solubility, and is preferably added in an amount of 9.0 wt% to 34.0 wt% with respect to the total composition ratio. When the glycerin is added in an amount exceeding 34.0% by weight, the preservative ingredient may become excessive and a problem may arise in formulation of the final product. If the glycerin is added in an amount of less than 9.0% by weight, drying may proceed rapidly, Lt; / RTI >

The purified water is preferably a substance that smoothes agitation with glycerin, titanium dioxide and polyacrylic acid, and is preferably added in an amount of 5.0 wt% to 16.0 wt% with respect to the total composition ratio. When the purified water is added in an amount of more than 16.0% by weight, the shape of the agitated product formed in the above step is discarded. When the added water is added in an amount of less than 5.0% by weight, solidification of the agitated product, It becomes difficult to stir with another stirring object at the subsequent stage.

The titanium dioxide is rich in minerals and blocks UVA and UVB, and is preferably added in an amount of 1.0 wt% to 5.0 wt% with respect to the total composition ratio. When the titanium dioxide is added in an amount exceeding 5.0% by weight, the mineral component is excessively eluted and becomes non-solvent. When the titanium dioxide is added in an amount of less than 1.0% by weight, the effect of ultraviolet ray blocking is reduced.

On the other hand, the polyacrylic acid thickener functions as one of the ingredients for forming the second agitator, and is preferably added in an amount of 60.0 wt% to 70.0 wt% with respect to the total composition ratio. When the polyacrylic acid is added in an amount exceeding 70.0% by weight, the tackiness can be increased. However, when the polyacrylic acid is added in an amount of less than 60.0% by weight, agitation can not be performed smoothly due to high tackiness. This may not be uniform.

Ⓒ Step

The step c) of the present invention is a step of agitating 85.0 to 95.0% by weight of purified water and 5.0 to 15.0% by weight of agar at a temperature of 90 to 100 ° C to form a third agitated product,

85.0 wt% to 95.0 wt% of purified water and 5.0 wt% to 15.0 wt% of agar are stirred at a temperature of 90 ° C to 100 ° C to form a third agitated product.

The purified water is added in order to facilitate stirring in the formation of the third stirred product, and it is preferable that 85.0 wt% to 95.0 wt% of the total water is added to the total composition ratio. When the purified water is added in an amount of more than 95.0% by weight, the shape of the agitated material to be stirred is reduced. When the added amount is less than 85.0% by weight, the agitated material is solidified, It becomes difficult to stir.

The agar is a viscous complex polysaccharide mixture which is extracted by physical and chemical treatment using seaweed or the like as a main raw material, and is preferably added in an amount of 5.0% by weight to 15.0% by weight based on the total composition ratio. When the agar is added in an amount exceeding 15.0% by weight, it is uneconomical due to excessive addition, and when it is added in an amount of less than 5.0% by weight, the function of normalizing blood purification and hormone secretion, which are main effects of the agar, becomes weak.

Meanwhile, the above components are stirred through a stirrer or the like in an amount satisfying the respective composition ratios, and it is preferable to stir while maintaining a constant temperature of 90 ° C to 100 ° C. This is because the viscosity of the third agitator may become too weak if the components are stirred above 100 ° C, and if the components are stirred below 90 ° C, the viscosity of the third agitator may become too high.

Ⓓ Step

The step (d) of the present invention comprises the steps of mixing 90.0 to 98.5% by weight of glycerin and 1.5 to 10.0% by weight of sodium polyacrylate to form a fourth agitated product,

90.0 wt.% To 98.5 wt.% Of glycerin and 1.5 wt.% To 10.0 wt.% Of sodium polyacrylate are stirred to form a fourth agitated material.

The glycerin is a component added to exert wettability and solubility, and is preferably added in an amount of 90.0 wt% to 98.5 wt% with respect to the total composition ratio. When the glycerin is added in an amount of more than 98.5% by weight, the preservative component becomes excessive, which may cause problems in formulation of the final product. If the glycerin is added in an amount of less than 90.0% by weight, Lt; / RTI >

The sodium polyacrylate is preferably a sodium salt of an acrylic acid polymeric material and is added in an amount of 1.5% by weight to 10.0% by weight based on the total composition ratio. When the sodium polyacrylate is added in an amount of more than 10.0% by weight, molecular squeeze of the sodium polyacrylate functioning as a stabilizer or the like may occur, and a change in the physical properties of the agitated product (for example, progress of solidification) may be conspicuous If it is added in an amount of less than 1.5% by weight, the stabilizer function may be insignificantly dispersed and the stirring may not be smoothly performed.

The components as described above are agitated through a stirrer or the like in an amount satisfying the respective composition ratio ranges to form a fourth agitated product.

In the step of the present invention, the fifth agitated product of step (b) is defoamed and 0.2 to 0.5 part by weight of alminum glycinate is added to the defoated fifth agitated product based on 100 parts by weight of the fifth agitated product, Adding 5.0 to 10.0 parts by weight of glycerin and stirring them to form a sixth agitator,

Degassing process is performed to remove air or foam present in the fifth agitated product, and the fifth agitated product subjected to the degassing process is mixed with 0.2 to 0.5 parts by weight of aluminum glycinate based on 100 parts by weight of the fifth agitated product, And 5.0 parts by weight to 10.0 parts by weight of glycerin are added and stirred to form a sixth agitator.

The aluminum glycinate is added to form the sixth agitated product in the form of a patch, and is preferably added in an amount of 0.2 part by weight to 0.5 part by weight based on the total weight. When the aluminum glycinate is added in an amount of more than 0.5 parts by weight, the pH may be irregularly controlled (strongly acidic or strong basic) and the value of the product may be lost. When the amount of the aluminum glycinate is less than 0.2 parts by weight, It is difficult to form the sixth agitated product in the form of a patch.

The glycerin is added to exert wettability, and is preferably added in an amount of 5.0 to 10.0 parts by weight based on the total weight of the composition. When the glycerin is added in an amount of more than 10.0 parts by weight, the preservative component may become excessive to cause problems in formulation of the final product. If the glycerin is added in an amount of less than 5.0 parts by weight, the drying may proceed rapidly, have.

The components as described above are stirred through a stirrer or the like to a content that satisfies the respective composition ratio ranges to form a sixth agitated product.

Step

The step of the present invention is a step of conveying the sixth stirred material in step (b) to a coater while maintaining a constant temperature of 70 - 75 ° C by using either a conveyor or a transfer tank,

In this step, the sixth agitator is transported to either the conveyor or the transfer tank using a conveyor or a transfer tank to coat the agitator on a flat surface. At this time, the temperature of the conveyor is preferably maintained at a constant temperature of 70 to 75 ° C. When the temperature is higher than 75 ° C., the viscosity becomes too low at the time of conveyance, Gelation is started in the transferring device (or transferring tank) at the time of transferring, so that it becomes difficult to coat the transferring material in a flat state. It is to be understood that any means other than the conveyor or the transfer tank may be used in the present invention.

Step

In the step of the present invention, the sixth agitated material conveyed to the coater of the step (b) is gelated on a plane through the cooler, and after coating with the support for supporting the agitated sixth agitated material, As a step of forming a gel,

The sixth agitated material conveyed to the coater is gelatinized in a planar state through a cooler, and the temperature of the cooler is preferably maintained at a temperature between minus 5 ° C and image 5 ° C. If the temperature of the cooler is 5 ° C or higher, the gelation may not be completed and the thickness of the coating material may not be constant. If the temperature of the cooler is less than 5 ° C, the gelatinization may be partially gelled, Can be.

On the other hand, a coating gel is formed by coating after laminating with a support for supporting a sixth agitated material gelled in a plane through the cooler.

As shown in FIG. 2, the support may be formed by bonding a nonwoven fabric to one surface of a polyurethane film, applying a water-soluble hydrogel to one surface of the nonwoven fabric or one surface of the release film, And the release film. The polyurethane film may be polyurethane having high air permeability and air permeability. By using polyurethane having air permeability, there is an advantage that the active ingredient can be smoothly penetrated into the skin at the time of long-time attachment and the inconvenience of attachment can be solved.

The water-soluble hydrogel may further contain 38.0 wt% to 59.6 wt% of polyacrylic acid, 8.0 wt% to 18.4 wt% of glycerin, 0.8 wt% to 1.2 wt% of sodium hydroxide, 0.8 to 1.2% by weight of polysorbate 60, 0.8 to 1.2% by weight of polysorbate 60 and 30 to 40% by weight of purified water.

Among the components constituting the water-soluble hydrogel, the polyacrylic acid is preferably used as a polymer polymer in an amount of 38.0 wt% to 59.6 wt%.

The polyacrylic acid is preferably used singly, but polyacrylic acid, polymethacrylic acid, polyacrylic acid copolymer, polymethacrylic acid copolymer, etc. may be used alone or in combination. If the polyacrylic acid content exceeds 59.6 wt% based on the total composition ratio, the release rate of the hydrogel is lowered. If the polyacrylic acid content is less than 38.0 wt%, it is difficult to maintain the patch shape, There is a possibility that a problem of degradation may occur.

The glycerin may exert a function of a moisturizing softener, but may also impart viscosity to improve spreadability (spreadability). The preferable content of the glycerin is 8.0 wt% to 18.4 wt%.

The sodium hydroxide dissolves the gelated hydrogel into a fluidized state, and the preferable content of the sodium hydroxide is 0.8 wt% to 1.2 wt%.

The agar is a viscous complex polysaccharide mixture which is extracted by physical and chemical treatment using seaweed or the like as a main raw material, and has the effect of purifying the blood of a cold person and normalizing hormone secretion from the viewpoint of function, Is from 0.8 wt% to 1.2 wt%.

In addition, polysorbate 60 may be added as a surfactant (a mixture of substances having different properties), and the polysorbate 60 is preferably added in an amount of 0.8 wt% to 1.2 wt% based on the total composition ratio.

The support formed as described above serves to support the sixth agitated product, and the sixth agitated product and the support are coated after laminating to form a coating gel.

Step

In the step of the present invention, the coating gel of step (1) is aged at a temperature of 55 to 60 ° C for 68 to 72 hours, and the aged coating gel is dried to form a patch As,

In this step, the coating gel is aged at a constant temperature of 55 ° C to 60 ° C for 68 hours to 72 hours. The aging period is most preferably from 68 hours to 72 hours. When the aging time exceeds 72 hours, the coating gel can be gradually cured. When the aging time is less than 68 hours, the viscosity becomes too much, have.

After the aged coating gel is dried for a predetermined period of time, the coated gel is shaped into a shape corresponding to the application site of the human body, for example, the vicinity of the eye, thereby producing a patch.

Step

The step of the present invention is a step of packaging a patch of a step,

In this step, the patches may be packaged and commercialized by various methods including previously known methods for commercializing the patches after the step. Further, in order to ensure the cleanliness of the product, the vacuum sterilization process and the like before packaging may be further roughed.
