Abstract

PROBLEM TO BE SOLVED: To provide a pack capable of efficiently gelatinizing alginic acid on skin.SOLUTION: The pack is gelatinized on skin when a first solution containing sol alginate and a second solution containing a metal ion gelatinizing the sol alginate are mixed together. The first solution is stored in an application container from which the solution is discharged to be applied onto skin, while the second solution is stored in a spray device by which the solution is discharged in atomized or foamed form. After applying the first solution to skin using the application container, the second solution is sprayed in an atomized form toward the first solution applied to the skin using the spray device. In this way, the gelatinized pack can be formed on the skin.

Description

  The present invention relates to a pack used by applying to the skin.

Masks and packs for skin care such as supplying moisture to the skin and supplying various nutrients are used.
The pack is generally in a state of relatively high viscosity in order to keep the state applied to the skin for a certain period of time and absorb moisture, skin care ingredients, etc. into the skin, and solidifies into a sheet after being applied to the skin. Things are also known. As for the pack, those that do not solidify into a sheet after use are washed away, and those that solidify into a sheet are removed by peeling off the sheet.

  Moreover, the said mask for packs is known, and the component similar to a back | bag is made to adhere on the sheet | seat used as bases, such as a nonwoven fabric. In the case of a mask, the base sheet is peeled off after use.

  As a pack base material, one using an alginate has been proposed (see, for example, Patent Document 1). Applying to the skin after mixing the first agent containing the sol alginate solution and the second agent containing the divalent metal ion that reacts with the sol alginate and gels, The sol-like alginate is gelled to form a pack, and skin care ingredients are retained on the skin.

JP 2011-74019 A

  By the way, since the gelation of the sol-like alginate is started when the first agent and the second agent are mixed, the first agent and the second agent are mixed and then applied to the skin. In this case, the sol-like alginate may be gelled, and it is necessary to apply the pack quickly, or it is necessary to add a gelling retarder as described in Patent Document 1. Even when gelation is delayed by the retarder, since the sol-like alginate is finally gelled, there is a time restriction on the application anyway.

Further, if the time required for gelation is lengthened, the pack is not easily solidified, and the time required for the pack may be increased.
Alginate is a dietary fiber derived from seaweed, for example, and is highly safe for use as food, but it is preferable not to add a retarder other than a skin care ingredient for pack use.

  In addition, it is preferable that a skin care ingredient suitable for a pack using alginate is included, for example, not only moisturizes the skin sufficiently while backing, but also moisturizes for a long time after backing. Is required.

  This invention is made | formed in view of the said situation, and it aims at providing the pack which can gelatinize a sol-form alginate efficiently on skin.

  The pack according to claim 1 is further applied onto the first solution containing a sol-like alginate applied to the skin and the first solution applied to the skin to gel the sol-like alginate. And a second solution containing metal ions.

In the first aspect of the invention, the first solution containing the sol-like alginate, that is, the solution of the sol-like alginate not containing the second solution and not gelling is applied to the skin. While the solution is applied to the skin, the sol alginate does not gel. Thereby, there is no restriction | limiting in the application time, and it can apply | coat a 1st solution to skin with a margin. Therefore, a retarder that delays the gelation of alginate is not required.
Gelation starts when the second solution is applied to the first solution already applied to the skin, and the sol alginate can be gelled in a short time. Therefore, no gelling accelerator is required and the pack time does not become long because the pack is slow to solidify.

In addition, even when the first solution containing the sol-like alginate before gelation has low viscosity and high fluidity, it is possible to immediately apply the second solution after applying the first solution to the skin. The gel-like alginate can be gelled to keep the first solution on the skin. In addition, if the sol-like alginate of the first solution is hardly gelled, it is also possible to peel off the gelled pack after the packing and remove it.
In addition, any part of the skin can be packed, and the range and shape of the pack can be freely set. That is, the range and shape to which the first solution is applied are free, and can be freely packed anywhere on the skin of the body.

  The pack according to claim 2 is characterized in that, in the invention according to claim 1, the second solution is accommodated in a spray device that discharges the solution in the form of a mist or foam.

  In invention of Claim 2, after apply | coating the 1st solution to skin, the 2nd solution is discharged to the 1st solution on the skin in the form of mist or foam with a spray device, and the 2nd solution is made into the 1st solution. By bringing the solution into contact, the first solution can be gelled and held on the skin.

  That is, after the first solution is applied to the skin, the second solution is applied onto the first solution without touching the first solution by discharging the second solution onto the skin in the form of a mist or foam. Is possible. Thereby, it can prevent that a hand gets dirty when making a 2nd solution contact a 1st solution.

When the second solution is applied by the spray device, it is not necessary to bring the first solution into contact with the spray device, and the spray device can be prevented from becoming dirty.
In addition, it becomes possible to apply the second solution substantially evenly to the surface side of the applied first solution compared to the case where the second solution is applied by hand, and the sol-like state of the first solution on the skin Alginate can be gelled substantially uniformly.

  The pack according to claim 3 is the invention according to claim 2, wherein the first solution is stored in an application container that discharges the solution to the skin, and the application container stores the first solution. And the spray device containing the second solution.

  In the invention according to claim 3, if the application container has a structure in which the solution is directly applied to the skin, when applying the first solution to the skin, there is no need to get the hands dirty. Even if the solution is applied to the hand, the first solution can be prevented from being gelled by hand. In addition, the pack is distributed and sold as a product consisting of an application container and a spray device, and is handed over to the customer. It is easy to handle and the first solution and the second solution are wrong before use. It is possible to prevent gelation by mixing.

  The pack according to claim 4 is the invention according to any one of claims 1 to 3, wherein the first solution includes sodium alginate as a sol-like alginate and a moisturizing component having a moisturizing effect. And the second solution contains calcium chloride that dissociates calcium ions as the metal ions, and the calcium chloride concentration of the second solution is 0.1 wt% to 3 wt%.

  In the invention described in claim 4, the material can be easily obtained at low cost. On the other hand, if the calcium chloride concentration is less than 0.1%, the gelled calcium alginate may be soft and the holding ability on the skin may be too small. On the other hand, if the calcium chloride concentration is higher than 3%, the calcium alginate gel may become too hard, and there is a possibility that the amount of materials is increased and the cost is increased. The concentration of sodium alginate in the first solution is preferably the same molar concentration as that of calcium chloride in the second solution in consideration of the reaction efficiency. Therefore, the concentration of sodium alginate is also changed in accordance with the concentration of calcium chloride. It is preferable.

  ADVANTAGE OF THE INVENTION According to this invention, the usability improvement in the pack using an alginate gel can be aimed at.

An embodiment of the present invention will be described.
The pack of this embodiment includes a first solution containing a sol-like sodium alginate aqueous solution and a second solution containing a calcium chloride aqueous solution.
It is known that when an aqueous solution of calcium chloride is brought into contact with a sodium alginate solution, the sodium alginate solution becomes a calcium alginate solution and gels. The first solution is gelled by adding the second solution to the first solution at the room temperature level. This calcium alginate gel contains a relatively large amount of water and can be replenished with moisture by keeping it in the skin. The first solution is not limited to a sodium salt as long as it is a soluble alginate.

  The second solution is basically an aqueous calcium chloride solution and contains calcium chloride in a weight percentage of, for example, 0.05% to 5%. Moreover, it is preferable that calcium chloride is contained in the second solution by weight%, for example, 0.1% to 3%, and more preferably 0.5% to 2%. The second solution is not limited to calcium chloride, and is a cation capable of gelling sol-like alginate with a salt that dissociates other divalent calcium ions or a divalent cation other than calcium. Any ion can be used.

In the first solution, the sodium alginate is set to have approximately the same molar concentration with respect to the calcium chloride of the first solution. However, since sodium alginate is a polysaccharide and is a kind of so-called dietary fiber, the molecular weight varies and varies depending on raw materials, production methods, and other factors. Therefore, for example, the weight% of alginic acid at the same molar concentration as calcium chloride having a weight% of 0.05% to 5% is not determined.

  Alginic acid is a polysaccharide containing D-mannuronic acid, which is a monosaccharide having a carboxyl group, and α-L-guluronic acid, which is a C-5 epimer and having a carboxyl group, and these are mixed. In the state, each monosaccharide is a pyranose type and bonded by a 1,4-glycoside bond. For example, a block in which D-mannuronic acid is polymerized and a block in which α-L-guluronic acid is polymerized Are mixed. The amount ratio of each block mainly depends on the origin. In addition, D-mannuronic acid and α-L-guluronic acid may be alternately polymerized one by one, and the alternately polymerized one has the most flexibility, and has a pH close to neutrality in water. It is easy to melt.

The block of α-L-guluronic acid consisting of 6 residues or more forms a stable complex with a divalent cation (Ca _2+, etc.) to form a three-dimensional gel. In the gel, it is mainly a homopolymer block of α-L-guluronic acid or D-mannuronic acid that creates an intermolecular bond, and the gel strength is determined by the content ratio of the block of α-L-guluronic acid It is.

  In addition, a moisturizing agent is blended in the first solution. Moisturizers include amino acids, pyrrolidone carboxylic acids, lactic acid, hyaluronic acid, mucopolysaccharides such as chondroitin sulfate, polyhydric alcohols such as glycerin, propylene glycol, butylene glycol, sorbitol, protein hydrolysates such as soluble collagen, elastin, and keratin. Various known humectants such as degradation products, animal fats and oils, vegetable fats and oils can be used.

  In this embodiment, the 1st solution is accommodated in the application container. The application container can accommodate the first solution as a container and is configured to be able to apply the first solution to an object such as skin from the opening side of the container. For example, the application container includes a resin-made flexible container body having an opening for filling and application of the first solution, a cap that is detachable while closing the opening, and an opening inside the cap. And an inner plug having a foam rubber pad provided to be closed. The inner plug is fixed in a state in which the opening of the container main body is closed, but the foamed rubber pad is provided with a number of holes through which liquid leaks. The liquid in the container body can be applied to the skin so that the first solution is leaked and spread with the inner plug while the inner plug is in contact with the skin by pressing the container. Thereby, the first solution can be applied to the skin without touching the first solution.

  In the case of a highly viscous solution, a pad having a larger mesh than the above-described foamed rubber pad may be used as the inner plug. Moreover, as an application | coating container, the spray apparatus for the below-mentioned 2nd solution may be used, and it is good also as what discharges a 1st solution in the shape of a mist or foam, and apply | coats to skin. Further, as the application container, a roll-on container that can apply the first solution to the skin using the ball as a roller by moving the application container in a state where the ball is rotatably provided in the opening and the ball is in contact with the skin is used. It may be a thing.

  The application container is preferably capable of applying the first solution to the skin directly from the opening of the container. For example, the container may be spread by hand after the first solution is dropped (flowed down) on the face. In this case, it is possible to use the first solution once received by hand and then applied to the face.

  The 2nd solution is accommodated in the container of the spray apparatus. The spray device, for example, discharges the second solution in a mist or foam form from a nozzle by gas pressure. Further, the spray device may be a spray device using a manual pump instead of using the gas pressure for discharging the first solution. That is, the spray device (spraying device) may be any device that can discharge (spray) a solution in the form of a mist or foam.

In such a pack, the first solution is stored in a coating container, and the second solution is manufactured in a state where the second solution is stored in a container of a spray device, and is distributed and sold. At this time, the amount of the first and second solutions in the application container and the container of the spray device may be set so as to be used up once, and the product just opened each time may be used. Further, the first and second solutions that can be used a plurality of times may be filled in each container and used. In view of cost, the latter is preferable, but the former is preferable in order to prevent contact between the first solution and the second solution and contamination, and to appeal to the purchaser a high-quality feeling and fresh feeling.
In addition, you may enable it to replenish a 2nd solution or a 1st solution to a spray apparatus or an application | coating container using the container for refilling. In addition, when the spray device includes a container, a cap that closes the opening of the container, and a discharge nozzle and a pump device provided in the cap, the empty container is filled with the second solution. It is good also as what is exchanged for a container.

  According to the pack as described above, after applying the first solution containing sol-like sodium alginate to the skin, the aqueous solution of calcium chloride as the second solution is sprayed or foamed on the first solution applied to the skin. The sol-like alginate can be gelled and solidified to some extent. The hardness of the gel is preferably such that, for example, calcium alginate gelled into a sheet can be peeled from the skin by hand.

  However, the gel does not necessarily have to be hard enough to be peeled off by hand, and the gelled calcium alginate solution can be washed away with water, etc. after the pack is finished, or wiped with soft paper, cloth or cotton. Good. Moreover, although the skin where a pack is used is a face, for example, it is good also as what is used for the skin of any part of the whole body. For example, it may be an limb such as an elbow, a palm, a knee, a sole of a foot, a chest, an abdomen, a back, or a buttocks. The application shape and application range at this time are also free, and can be made into an optimum shape for the application location, applied to a relatively narrow range, or applied to a wide range. Basically, when the first solution is applied, the application shape and the application range are determined, and the second solution may be applied by a spray device corresponding to the application range and the application shape of the first solution.

  In addition, when the alginate is gelled by applying the first solution to the skin in the application container at the time of application and spraying the second solution on the first solution, Packing can be performed without applying a solution, and it is not necessary to wash hands and wipe dirt from the hands while the hands are dirty when packed. Also, by holding the spray device with the hand with the first solution, the spray device becomes dirty, or the second solution is dropped from the spray device to the hand with the first solution, and the sol-like alginate is formed by hand. It can prevent gelation.

  The gel obtained by gelling this sol-like alginate solution can be brought into a moist state rather than a dry state by supplying water to the skin by contacting the skin with a relatively high amount of water. . In particular, when the second solution is sprayed on the first solution applied to the skin, the outer surface side far from the skin of the first solution is gelled first, and the first solution is held on the skin so that it does not flow. In this case, since gelation proceeds from the side far from the skin toward the skin side, the side in contact with the skin side is in a solution state without gelling for a while after the start of the pack, and the skin is in the pack. In this state, water can be sufficiently retained.

  Further, by adding a moisturizing component to the first solution as described above, the moisturizing effect of the skin can be continued after the pack due to the synergistic effect with the sodium alginate gel.

  In addition, the kit product is similar to the kit product in the so-called pharmaceutical product in which the application container and the spray device are filled with the first solution and the second solution, respectively. It is possible to prevent the application container and the spray device from becoming dirty. Moreover, by making it the kit product similar to a pharmaceutical, the mistake which mixes a 1st solution and a 2nd solution and gelates it before use can also be prevented.

  Moreover, what masked and packaged what formed the layer of the gelatinized calcium alginate on the sheet | seat which consists of nonwoven fabrics as a mask can be considered. In this case, for example, a calcium chloride solution is brought into contact with a sodium alginate solution in a sol form on the sheet to be gelled. Although it is preferable to automate the formation of the calcium alginate gel on the sheet to hermetic packaging, it is difficult to automate the formation of the calcium alginate layer on the sheet, and it is difficult to reduce the cost. On the other hand, in the manufacture of the pack of the present invention, basically, the first solution and the second solution are manufactured, and then the containers are filled into the containers. Can be achieved.
