Description

Transparent nose pack and method for manufacturing the same

The present invention relates to a peel-off type nose pack, and more particularly, to a transparent nose pack that is convenient to use because no residue remains on the skin from which the pack sheet is removed, and the time required for drying after attachment is short, and to a method for manufacturing the same. .

Peel-off type nose pack is designed to remove the pore blackheads after cleansing or around the nose by applying moisture to the nose, and then leaving the pack for a certain period of time to dry when removed. will be.

Conventionally known peel-off type nose packs are commercialized in various forms in the form of jelly, paste, and powder. However, an emulsion-like coating cosmetic is applied on a release film and dried while controlling the thickness to form a layered form. Above, a structure in which a base material such as a nonwoven fabric is covered and integrally bonded is widely adopted.

The coating cosmetic that comes in contact with the skin of the nose and the nose is dissolved in the lotion applied to the nose, and the blackheads of the pores and the sebum around them are dissolved and converged.At the same time, the moisture of the coating cosmetic begins to evaporate and dry through the nonwoven fabric.

By drying as described above, the coating cosmetic contracts and tightens the skin such as the nose, and at this time, the nose pack can be removed without pain when the surface of the coating cosmetic in contact with the skin such as the nose is not completely dry.

Here, if the thickness of the nonwoven fabric employed in the nose pack is thick, the drying time is increased, and in this case, stimulation due to contraction of the coating cosmetic is also gradually applied, making it difficult for the user to experience.

If the coating material of the nose pack is completely dry to the surface of the nose, etc., when the nose pack is removed, it is pulled to the skin of the nose, causing pain as well as severe damage to the skin.

Therefore, the condition required for the nose pack is that the drying of the coating cosmetics must proceed quickly, and the thickness of the nonwoven fabric supporting the coating cosmetics is made thin so that the user can feel the irritation caused by the drying.

In order to obtain the above characteristics, research and development on coating cosmetics and substrates have been conducted in the past.

As for the nonwoven fabric that is widely used as a base material in a peel-off type nose pack, as disclosed in Patent Document 1, a two-layered nonwoven fabric processed with a hydrophilic layer on the side to which the coating cosmetic is bonded and a water repellent layer on the other side is known. Has been.

However, in the nonwoven fabric with a double structure of the water repellent layer and the hydrophilic layer, the coating cosmetic material permeates and contains only the hydrophilic layer, so the bonding strength with the nonwoven fabric is weakened. For this reason, when the dried nose pack is removed from the nose, there is a gap between the nonwoven fabric and the coating cosmetic material. Since separation causes a problem in that the residue remains on the skin such as the nose, the above double structure is hardly adopted.

Non-woven fabric is a material that is easy to bond integrally with coating cosmetics, but the quality of the product varies greatly depending on its thickness and material.

In other words, thick nonwoven fabrics have a relatively strong self-resilience, so even if they are attached to match the contours of the nose, they do not adhere to and separate from the curved part, and the space of the fibrous tissue is also narrow, so the amount of moisture evaporated through it is limited and drying. The time required will be longer.

The thin nonwoven fabric fits well with the contours of the nose and can be adhered closely, and the time required for drying is short due to the large space of the fibrous tissue.

However, when the coating cosmetic material is coated on a thin nonwoven fabric, there is a problem that it penetrates through the space of the fibrous tissue and a part of the coating cosmetic material is exposed to the back side.

The coated cosmetic material exposed through the back side of the nonwoven fabric comes into contact with the unreleased side of the release film while being wound on the bobbin, and after a period of time, the release film and the nonwoven fabric are integrally bonded by the coat cosmetic material between the back side. It often becomes a defective product that cannot be used.

For this reason, most of the commercially available nose packs are manufactured by first drying the coating cosmetic applied to the release film, covering the nonwoven fabric with a semi-dried surface, pressing lightly, and then drying the secondarily.

However, according to the above-described manufacturing method, coating cosmetics cannot seep out to the back side of the nonwoven fabric, but there is a problem in that there is a problem of waste due to the addition of unnecessary equipment and troubles in operation because two drying furnaces must be provided.

As described above, it is expected that all problems encountered by employing a nonwoven fabric in a conventional nose pack can be solved by employing a mesh as a base material.

Because the mesh is thin, it can be easily deformed to match the curves of the nose, and the opening area is wide, so the drying time of the coating material can be shortened. I can.

However, in the case of employing a mesh for the nose pack, the area of the mesh that is depressed in the coating cosmetic becomes significantly narrower than that of the nonwoven fabric when it is carried out by the conventional manufacturing method, and thus the bonding strength between the coating cosmetic and the mesh is considerably weakened. When it is removed from the skin, the cosmetic material is not completely removed, and a part remains on the skin.

Therefore, in order to employ a mesh as a base material for a nose pack, a method for enhancing the bonding strength between the mesh and the coating cosmetic must be devised in relation to the manufacturing process or the components of the material.

Specific examples of coating cosmetics include polyhydric alcohols and polyhydric alcohol fatty acid esters as main components, and a composition obtained by adding a scrub agent or a pigment as other components and mixing with purified water, as described in Patent Document 2, and described in Patent Document 3 As described above, a polymer compound having a salt-generating group or a composition containing a synthetic polymer compound as a main component is known.

A commercially available nose pack employs a raw material related to the above composition, but employs a white-based coating cosmetic to which inorganic pigments such as titanium dioxide powder and iron oxide powder are added.

However, the inorganic pigment in the nose pack only provides a visual effect that makes the removed blackhead stand out from the nose pack, regardless of the removal of the blackhead. This is part of the inorganic pigment when the nose pack is peeled off the nose. Remains on the skin, leaving a dirty mark.

On the other hand, coating cosmetics have different physical properties depending on the ingredients, but the increase in the removal efficiency of blackheads is excessively dissolved in moisture, which gives a feeling of discomfort due to severe stickiness during use, and if the ingredients are adjusted so that they do not become sticky by improving this, it will quickly meet with moisture. As it does not dissolve properly, the time required to remove the black head becomes longer.

Japanese Utility Model Registration No. 3034427 Japanese Patent Laid-Open No. 2019-14671 Japanese Patent Laid-Open No. 1993-221843

Accordingly, it is an object of the present invention to provide a transparent nose pack that is less sticky when used, a film can be formed in a short time, and does not leave a residue of a film cosmetic when peeled off from the skin.

Another object of the present invention is to provide a method of manufacturing a transparent nose pack that can be firmly bonded to prevent separation between a coating cosmetic and a thin substrate.

The present invention for realizing the above object is to form a film through the complementary action of polyvinylpyrrolidone and VP/VA copolymer, and hydroxyacetophenone and 1,2 hexanediol as an antioxidant, and dipotassium as a skin conditioning agent. It is characterized by bonding a mesh to a coating composition consisting of a coating composition containing glycyrrhizate, polysorbate 60 and sorbitansquioleate as an emulsifying agent, and a Virginia prickly pear extract as a skin astringent.

An appropriate amount of aloe vera leaf extract, tocopheryl acetate, and dimethicone for suppressing bubble formation may be added to the above-described coating composition as a moisturizing agent.

And the component content of the coating composition, polyvinylpyrrolidone 10 to 35 parts by weight, preferably 24 parts by weight, VP/VA copolymer 5 to 25 parts by weight, preferably 14 parts by weight, hydroxyacetophenone 0.1 to 1.2 parts by weight Preferably 0.5 parts by weight, 1,2-hexanediol 0.1 to 1.4 parts by weight, preferably 0.6 parts by weight, dipotassium glycyrrhizate 0.01 to 0.20 parts by weight, preferably 0.08 parts by weight, polysorbate 60 0.05 to 0.50 parts by weight, preferably 0.21 parts by weight, sorbitan sesquioleate 0.03 to 0.07 parts by weight, preferably 0.05 parts by weight, and Virginia Pomegranate extract 0.07 to 0.13 parts by weight, preferably 0.1 parts by weight, dispersed in an appropriate amount of denatured alcohol and purified water It is obtained by dissolving.

In addition, a moisturizing agent that may be added to the coating composition is 0.1 parts by weight of aloe vera leaf extract, 0.01 parts by weight of tocopheryl acetate, and 0.5 parts by weight of dimethicone as a skin protectant may be further added.

The modified alcohol for dispersing and dissolving the above-described component substances is 25 to 35 parts by weight, and purified water is 26 to 37 parts by weight.

The above-described mesh is a nylon yarn of 10 to 15 denier, and an opening dimension in the range of 0.84 to 2.0 mm may be employed.

In addition, the method of manufacturing the transparent nose pack of the present invention is to apply a coating cosmetic composition to the surface treated with the release agent of the release film, and then completely dry it while allowing it to naturally settle while moving by coating a mesh on the top surface of the coating cosmetic composition before entering the drying furnace. It consists of a process of perforating the resulting material with a transparent nose pack.

Since the transparent nose pack of the present invention is integrally bonded by concave mesh to a film used as a coating cosmetic material, it is possible to form a nose pack having a thin thickness. Accordingly, there is an advantage that the removal effect of the black head appears over the entire nose, since the thin nose pack can be attached by deforming to suit the curve of the nose, without being unreasonable.

In addition, since the nose pack of the present invention employs a mesh, drying of the film after being attached to the nose or the like is performed through the opening of the mesh.

Therefore, there is an advantage that the user does not feel bored since the time until drying after applying the nose pack is greatly shortened.

In addition, since no pigment is added to the nose pack of the present invention, the appearance is transparent, and the mesh is depressed into the inside of the coating cosmetic during the manufacturing process, so when the pack is removed from the nose or the like after use, the mesh and the coating cosmetic are separated together and the skin There will be no remnants left.

In addition, the film provided in the nose pack of the present invention uses polyvinylpyrrolidone and VP/VA copolymer as a film forming agent, so it is easy to prepare, and a hypoallergenic and elastic film can be obtained by the complementary action of the two components. When used, the surface dissolves quickly in the lotion, but it is not very sticky, so the texture is good.

In addition, according to the manufacturing method of the present invention, the net is completely dried by passing through a drying furnace while naturally settling on the top surface of the coating cosmetic composition. When the nose pack is peeled off, the net and the coating cosmetics are removed from the skin together, so the post-treatment is clean, and even at the facility scale, one drying furnace is required, which can eliminate excessive equipment problems and operational hassles.

1 is a schematic configuration diagram of a film forming machine according to the manufacturing method of the present invention.

The transparent nose pack of the present invention will be described in detail as follows.

The transparent nose pack of the present invention applies a coating cosmetic on a release film and covers a mesh thereon, but by passing the release film and the mesh through a drying furnace while moving the release film and the mesh at a constant speed, the mesh is completely dried while being immersed in the coating cosmetic. It was made to be joined.

In the present invention, the mesh is a nylon yarn of 10 to 15 denier, and a plain weave having an opening dimension of 0.84 to 2.38 mm is employed.

In the transparent nose pack of the present invention, polyfinylpyrrolidone and VP/VA copolymer are particularly suitable as the film forming agent contained in the film cosmetic, and the polyvinylpyrrolidone is 10 to 35 parts by weight, preferably 24 parts by weight. And, the VP/VA copolymer is added in an amount of 5 to 25 parts by weight, preferably 14 parts by weight.

Polyvinylpyrrolidone is an almost odorless white powder that is soluble in water, ethanol, isopropanol, etc., and forms a hygroscopic glossy film with excellent adhesion and cohesiveness when dried as a coating. If it is less than 10 parts by weight, the firmness of the film decreases, and if it exceeds 35 parts by weight, the cohesiveness becomes excessively high, and there is a fear of damaging the skin when the nose pack is removed.

VP/VA copolymer is a white powder that has the property of becoming a film when dried. It acts as a gelling agent to help disperse and dissolve polyvinylpyrrolidone. When it is dispersed and dissolved in a solvent, it becomes a transparent mucus and can be applied well on the release film. Make it possible.

In the present invention, if the amount of the VP/VA copolymer is less than 5 parts by weight, the gel formulation appears unsatisfactory, and if it exceeds 25 parts by weight, the hygroscopicity of polyvinylpyrrolidone is inhibited, so that the dissolution of the film is not satisfactory when using a nose pack.

Hydroxyacetophenone is an acicular crystal soluble in denatured alcohol, and in the present invention, it forms a film that traps moisturizers of other ingredients in the skin along with an antioxidant role to keep the skin moist even after removal of the nose pack. If this is less than 0.1 parts by weight, the moisturizing film formation is insignificant, and even if it exceeds 1.2 parts by weight, the moisturizing effect is not further enhanced.

1,2-Hexanediol is a transparent liquid with a peculiar odor. It is well soluble in water or oil and has excellent antibacterial properties. If it is less than 0.1 parts by weight, the antibacterial property is not guaranteed, and if it exceeds 1.4 parts by weight, the viscosity of the dispersion The thickness of the film to be applied may be decreased and may not be uniformly maintained.

Dipotassium glycyrrhizate is a water-soluble white powder whose molecular structure is similar to that of testosterone and exhibits skin damage recovery and sebum control effects, and its effect is low when it is less than 0.01 parts by weight, and the effect is not better even when it exceeds 0.50 parts by weight.

Virginia Pung Nyunhwa extract is a liquid that exhibits pore shrinkage and sebum removal effect by astringent action that gives a feeling of tension to the skin.If it is less than 0.07 parts by weight, the astringent action is weak, and if it exceeds 0.16 parts by weight, there is a high fear of irritation to sensitive skin.

Aloe vera leaf extract is a liquid that has an excellent effect of regenerating and soothing damaged skin and removing dead skin cells when blackheads are removed.If it is less than 0.07 parts by weight, the skin soothing effect is poor, and if it exceeds 0.16 parts by weight, the Virginia apex extract converges. There is a fear that the function will be reduced.

Polysorbate 60 is a yellow viscous liquid that acts to disperse substances that are well soluble in water and insoluble with each other. If it is less than 0.05 parts by weight, the dispersing effect is weak, and if it exceeds 0.50 parts by weight, the transparency of the nose pack of the present invention will be impaired. I have anxiety.

Sorbitanes sesquioleate is also a pale yellow liquid that activates and disperses the interface of components that are difficult to mix with each other.If it is less than 0.03 parts by weight, the surfactant effect is insignificant, and if it exceeds 0.07 parts by weight, the transparency of the nose pack of the present invention Becomes pale yellow.

Tocopheryl acetate is a yellow, odorless, viscous liquid with moisturizing and skin-activating effects. Since it is a substance that impairs transparency in the nose pack of the present invention, it is added in a very small amount. This may be less than 0.008 parts by weight, but if it exceeds 0.011 parts by weight, the nose pack may turn pale yellow.

Dimethicone, which imparts fluidity to the coating composition and prevents bubble formation, is a transparent mineral oil without odor, and can be added in an appropriate amount.

In the present invention, a denatured alcohol is added in an appropriate amount for dispersion of a lipophilic substance and purified water for dispersion of a hydrophilic substance.

The above-described component materials are dispersed and dissolved through the following process to form a film composition, and this film composition is applied on a release film and dried to form a film, and at the same time, it is considered to be integrated by pressing a mesh on the surface in a semi-dry state. To get the transparent nose pack of the invention.

The mixing time when each component material of the above-described film-forming composition is added to denatured alcohol and purified water and dispersed and dissolved is not particularly determined, and it is sufficient if it is confirmed that it is dispersed and dissolved without agglomeration with the naked eye, and the mixing speed is also particularly Although not determined, for example, it can be performed by dividing into a low speed of 20 rpm, a medium speed of 1500 rpm, a high speed of 2500 rpm, and a maximum speed of 3500 rpm.

Disperse and dissolve first, dipotassium glycyrrhizate is added to purified water and dispersed and dissolved while mixing at medium speed, and when dissolved without clumping, polyvinylpyrrolidone is continuously added and dispersed and dissolved at the same rate to prepare a sub-solution.

Separately from the above, hydroxyacetophenone and VP/VA copolymer are added to denatured alcohol and mixed at a low speed, and when dispersed to a certain extent, the mixture is mixed at medium speed to disperse and dissolve without clumping to obtain a main solution.

When polyvinylpyrrolidone is added to the main solution, mixing at a low speed and dispersing to some extent is mixed at a high speed to disperse and dissolve completely without agglomeration.

Then, the sub-solution is continuously added and mixed at a low speed to disperse without agglomeration, then the sub-solution is mixed at the highest speed to completely disperse and dissolve.

Polysorbate 60 and sorbitan sesquioleate, tocopheryl acetate, dimethicone, 1,2-hexanediol, Virginia fern extract, and aloe vera leaf extract were added to the main solution in which the above ingredient substances were dispersed and dissolved, When mixing at a low speed and dispersing without agglomeration, mixing at the highest speed to completely disperse and dissolve and defoaming to obtain a coating composition.

The obtained film composition is supplied to a conventional film forming machine shown in Fig. 1 to produce a sheet material for a nose pack.

In other words, the release film (2) treated with the release agent on one side is passed through the storage tank (4) containing the film cosmetic composition to be applied with a film cosmetic layer (6) of a certain thickness on the upper surface, and run toward the drying furnace (8). When doing so, the mesh 10 is supplied to the upper surface of the coating cosmetic layer 6.

When the mesh 10 supplied to the upper surface of the coating cosmetic layer 6 is supplied at a constant speed at the moving speed of the release film 2, it naturally subsides into the coating cosmetic layer 6.

In this way, the release film 2 and the mesh 10 moving at a constant speed enter the drying furnace 8 together and are recovered as a sheet material in a completely dry state.

When the mesh 10 is supplied to the top surface of the coating cosmetic layer 6, it naturally subsides, but as it passes through the drying furnace 8 and the coating cosmetic layer 6 is cured, the settling is in the vicinity of the top surface of the coating cosmetic layer 6. When stopped, the combination of the coating cosmetic layer 6 and the mesh 10 is made in a manner suitable for the nose pack.

As described above, the moisture content of the coated cosmetic layer 6 incorporated with the mesh 10 and completely dried is 5% by weight or less.

The coating cosmetic layer 6 covered with the mesh 10 and completely dried is punched in a subsequent process and formed into a desired nose pack.

Table 1 shows the results obtained for each evaluation item by providing the transparent nose packs obtained in Examples 1 to 7 described above for a sensory test.

The evaluation method is that when applying lotion to the nose of the volunteer and attaching the transparent nose pack obtained in Examples 1 to 7 above, the coating cosmetic dissolves in water and feels sticky, and it adheres and adheres to it while being deformed according to the bend of the nose, etc. Inspect whether the condition is maintained, measure the drying time until the skin feels tense due to the drying phenomenon of the coat cosmetic, and evaluate whether a part of the coat cosmetic remains on the skin when the nose pack is peeled off by the presence or absence of residues. In addition, it is evaluated whether part or all of the film cosmetic material is separated from the mesh when the mesh is separated from the skin as maintenance of the bonded state or partial separation.

[evaluation]

Both of the nose packs of Examples 3 to 7 had sticky surfaces, but not to the extent that it would make the procedure difficult, and in Examples 1 and 2, the tendency to adhere only when the nose pack was attached to the nose and pressed for about 30 seconds to 1 minute. This is presumed to be a phenomenon in which adhesion is promoted after the coating cosmetic is dissolved at body temperature.

The nose packs of Examples 6 and 7 showed a tendency to partially peel off the curved part of the nose area while being attached to the nose and then dried. The cause of some peeling is that when the nylon yarn of the adopted mesh is deformed according to the bend of the nose, the self-restoring force is weaker than the adhesive force and adheres to the skin. I guess there is something to be done.

Therefore, the denier of the mesh is suitable in the range of 10 to 15.

The drying time after adhesion of the nose pack was shortened as the opening dimension increased.

When removing the nose pack in Examples 6 and 7, a part between the mesh and the coating material was separated, and this was due to the large opening dimension of the mesh and the bonding area between the coating material and the mesh was relatively narrow. Since it is judged as a problem, it is desirable to adopt the opening dimension of the mesh within 2mm.

As described above, the transparent nose pack of the present invention employs polyvinylpyrrolidone and a VP/VA copolymer as a film forming agent, so that a film-like cosmetic material having low irritation and elasticity and excellent touch can be obtained.

In addition, since the film shape is maintained by integrally bonding the film cosmetic to the mesh, the overall thickness of the nose pack can be greatly reduced, so that it can be completely adhered to the curved part of the nose.

In addition, in the transparent nose pack of the present invention, since drying of the coating material is performed through the opening of the mesh, the time required for drying is shorter than that of a nose pack employing a conventional nonwoven fabric.

In addition, the manufacturing method of the present invention is to completely dry by passing through the drying furnace while naturally submerging by covering the top surface of the coating cosmetic material applied to the release film before entering the drying furnace. In addition, since only one drying furnace is required, there is no excess of facilities, and the operation of the drying furnace is also simplified.
