Description

  The present invention relates to a coating composition. More specifically, the present invention relates to a coating composition in which bubbles of a soluble gas are dispersed in a viscous material, and a large amount of small bubbles are dispersed in the coating composition.

  Conventionally, a coating composition such as a gel-like hairdressing agent is commercially available as a product in which bubbles are dispersed in a composition for the purpose of improving the appearance beauty and filled in a transparent tube container. For the purpose of improving such products, various techniques for dispersing bubbles in the coating composition and techniques for holding the dispersed bubbles have been proposed.

  For example, Patent Document 1 discloses a method for producing a foamed viscous material, which is a foamed viscous material in which bubbles having a diameter of 1 to 10 mm can be uniformly mixed in a stable state by using a predetermined porous plate. A manufacturing method is described. However, Patent Document 1 does not take into consideration that bubbles to be mixed are bubbles of a soluble gas, and does not consider mixing a large amount of bubbles.

  Patent Document 2 describes a method for producing a functional gel, in which fine bubbles are fed into a low-viscosity solution and then gelled by the addition of a gelling agent to retain the fine bubbles inside. Has been. However, in the production method of Patent Document 2, since the gelling agent is added after the gas is fed into water or a low-viscosity solution to cause gelation, the gas is not saturated and dissolved in the solution. Therefore, when a functional gel is produced using a soluble gas such as carbon dioxide, there is a problem that if it is left standing for a while, fine bubbles dissolve in water or a low-viscosity solution, and the bubbles disappear. Furthermore, the fine bubbles are nanobubbles or microbubbles, and there is a problem in terms of improving the appearance beauty. There is also a problem that it is difficult to hold a large amount of bubbles.

  In Patent Document 3, as a container filled with a viscous composition, the stability of bubbles mixed in the viscous composition can be improved by setting the oxygen permeation amount of the portion in contact with the contents within a predetermined range. Have been described. However, Patent Document 3 does not consider the bubbles to be dissolved gas bubbles and the amount of bubbles to be mixed.

  Patent Document 4 describes a composition for external use of carbon dioxide in which carbon dioxide is dissolved in a non-bubble state in a viscous material composed of water and a thickener, and a method for producing the same. No consideration is given to compositions that are only dissolved and in which carbon dioxide is dispersed as bubbles.

Coating compositions and coated products can be provided.

  By setting the diameter of the bubbles to 0.01 to 10 mm, it is possible to provide a coating composition that is more excellent in appearance and easily spreads a viscous material.

  Since the soluble gas is saturated and dissolved in the viscous material, it is possible to provide a coating composition that can obtain the maximum effect of the soluble gas in combination with the effect of the soluble gas in the bubble state.

  By using carbon dioxide gas as the soluble gas, it is possible to provide a coating composition having an external beauty, an effect of a viscous material, and a massage effect and blood circulation promoting effect by carbon dioxide gas.

  By using nitrous oxide gas as a soluble gas, it is possible to obtain a coating composition in which bubbles are stably dispersed without being affected by the beauty of the appearance, the effects of viscous materials, and the components contained in the viscous materials. Can be provided.

  By setting the viscosity of the viscous material at 25 ° C. to 1,000 to 200,000 mPa · s, it is possible to prevent the movement of bubbles in a stationary state and stably disperse, so that the appearance is further improved. An excellent coating composition can be provided.

  In the coated product of the present invention, since the coating composition in which the soluble gas is dispersed in a bubble state can be directly applied to an object for a fingertip or a palm, the effect of the soluble gas is easily obtained.

Thus, the soluble gas can be easily saturated and dissolved in the viscous material, and the air bubbles of equal size can be easily dispersed.

  In addition, by performing the bubble forming process in a container, a coating composition in which bubbles are dispersed can be easily produced.

FIG.1 (c) is sectional drawing which shows the state which decompressed the pressure in an aerosol container and generated soluble gas as a bubble.

  The coating composition of the present invention is a coating composition in which bubbles of a soluble gas are dispersed in a viscous material, and contains a soluble gas in 1 g of the coating composition at 25 ° C. and atmospheric pressure. It is characterized in that 0.02 to 1.5 ml of bubbles are dispersed.

  The viscous material can be prepared by dissolving or dispersing a viscosity modifier in a base.

  Examples of the viscosity modifier include water-soluble polymers, solid oils, and oils with high viscosity.

  Examples of the water-soluble polymer include microbial polysaccharides such as xanthan gum, dextran, succinoglucan, curdlan, and hyaluronic acid; carboxyvinyl polymer, (acrylic acid / itaconate steareth) copolymer, (acrylic acid / itaconic acid).

In particular, it is preferable to use microbial polysaccharides and cross-linked acrylic polymers from the viewpoint of stably holding bubbles dispersed in the viscous material, and it has high foamability and contains a large amount of bubbles in the viscous material. It is preferable to use a cellulosic polymer or a plant-based polysaccharide from the viewpoint that it can be easily formed.

  Further, a viscous material in which gelatin is dissolved has a characteristic that the viscosity changes depending on temperature, that is, a viscosity is low at a high temperature and a viscosity is high at a low temperature. Therefore, when gelatin is used as the water-soluble polymer, the viscosity and viscosity of the viscous material are low, the dissolution process and the bubbling process described below are performed, and then the viscosity of the viscous material is increased by lowering the temperature. It is possible to improve the retention of bubbles of the soluble gas.

When the content of the viscosity modifier is less than 0.1% by mass, it is difficult to obtain the effect of thickening the viscous material, and it tends to be difficult to hold the soluble gas in the viscous material in a bubble state. Moreover, when it exceeds 20 mass%, it will become sticky and there exists a tendency for a usability | use_condition to fall.

  Since the alcohol contains a base containing water in a specific ratio, the amount of the soluble gas dissolved in the base becomes lower than the amount of the soluble gas dissolved in the water. Thus, after the soluble gas dissolved in the viscous material is bubbled, the soluble gas is difficult to dissolve again in the viscous material, and the bubbles can be held stably.

  The content ratio (mass ratio) in the case of containing alcohols and water is preferably 1/99 to 90/10. When the monohydric alcohol is contained as the alcohol, the content ratio of the monohydric alcohol to water is preferably 1/99 to 40/60, and more preferably 5/95 to 35/65.

When the content of the surfactant is less than 0.05% by mass, the effect of containing the surfactant tends not to be obtained. Moreover, when it exceeds 20 mass%, it will become sticky and there exists a tendency for a usability | use_condition to fall.

  When the pH adjuster contains a cross-linked acrylic polymer such as carboxyvinyl polymer, the pH of the aqueous base is adjusted to increase the viscosity to prepare a viscous material. When the fatty acid is contained, the fatty acid is saponified. In the case of containing a styling resin that does not dissolve in water, it is used for the purpose of neutralizing and imparting water solubility, or facilitating dissolution of an active ingredient that is difficult to dissolve in a solvent.

  When the pH adjuster is contained, the content of the viscous material is preferably 5 to 9, more preferably 6 to 8. When the crosslinkable acrylic polymer is contained and the pH of the viscous material is less than 5, there is a tendency that the crosslinkable acrylic polymer is insufficiently crosslinked and the viscosity of the viscous material is difficult to increase. Further, when the pH is 9 or more, there is a tendency that irritation to the skin tends to occur, and further, the container tends to be corroded.

  When the powder is contained, the content in the viscous material is preferably 0.1 to 10% by mass, and more preferably 0.5 to 5% by mass. When the content of the powder is less than 0.1% by mass, the effect of containing the powder tends to be difficult to obtain. Moreover, when it exceeds 10 mass%, there exists a tendency for it to become difficult to disperse | distribute uniformly in a viscous material.

  The viscous material used in the present invention can be prepared by dissolving or dispersing a viscosity modifier in a base such as water. Moreover, the active ingredient etc. which are contained as needed can be prepared by dissolving in water or alcohol. Note that powder may be dispersed in the viscous material.

  The viscosity of the viscous material at 25 ° C. is preferably 1,000 to 200,000 mPa · s, and more preferably 5,000 to 180,000 mPa · s. When the viscosity of the viscous material is less than 1,000 mPa · s, there is a tendency that bubbles containing a soluble gas are hardly retained in the viscous material. Moreover, when it exceeds 200,000 mPa · s, it tends to be difficult to handle such as difficult to take out from the container.

  The coating composition of the present invention is excellent in appearance beauty because a large amount of bubbles containing a soluble gas are dispersed and held in a viscous material. This coating composition has not only an effect due to a viscous material but also an effect due to a soluble gas. Further, the presence of bubbles makes it easy to spread the viscous material on the application surface.

  The soluble gas in the present invention is a gas having a large amount dissolved in a solvent (for example, the Ostwald coefficient with respect to water is 0.5 or more), for example, carbon dioxide gas (Ostwald coefficient: 0.83), Nitrogen oxide gas (Ostwald coefficient: 0.59), and mixed gas thereof can be used. Among them, nitrous oxide gas is preferable from the viewpoint that the bubbles of the soluble gas disperse in a stable size in the viscous material regardless of the blending components such as a pH adjuster, and a massage effect and a blood circulation promoting effect are obtained. From this point, carbon dioxide gas is preferable.

  Note that a low-solubility gas (for example, an Ostwald coefficient with respect to water of less than 0.5) having a small amount of dissolution in a solvent may be used together with the soluble gas. Examples of the low solubility gas include nitrogen gas (Ostwald coefficient: 0.014), oxygen gas (Ostwald coefficient: 0.028), air (Ostwald coefficient: 0.017), and the like. By using a low-solubility gas in combination, the amount of gas dissolved in the viscous material can be adjusted, and the size and stability of the bubbles can be controlled. The content in the case of using a low-solubility gas in combination is preferably 70% by mass or less, more preferably 60% by mass or less, in the gas to be dispersed, from the viewpoint of sufficiently obtaining the effect of the soluble gas. preferable.

  The dispersion amount of bubbles containing a soluble gas in 1 g of the coating composition is 0.02 to 1.5 ml, preferably 0.03 to 1.2 ml, and more preferably 0.05 to 1.0 ml. When the amount of dispersion in 1 g of the coating composition is less than 0.02 ml, it tends to be difficult to obtain the effect of improving the feeling of use such as ease of spreading and the effect of the soluble gas itself. Also, if the amount exceeds 1.5 ml, the bubbles in the coating composition are large and the ratio of the viscous material is reduced. Therefore, it is difficult to obtain the effect of the viscous material, and the bubbles naturally break easily during application. There is a tendency that the effect of improving the feeling and the effect of the soluble gas itself are hardly obtained.

The dispersion amount of bubbles containing a soluble gas in 1 g of the coating composition in the present invention is measured at 25 ° C. and atmospheric pressure. This dispersion amount (Vml) is the volume per 1 g of viscous material (coating composition) in which the volume per 1 g of viscous material (before dispersing the soluble gas) is X ml and the bubbles containing the soluble gas are dispersed. If Y is Yml, the mass of the dispersed dissolved gas is negligibly small.
Formula: Y-X = V
It can ask for.

  0.01-10 mm is preferable and, as for the diameter of the bubble containing the soluble gas disperse | distributed in the viscous material, 0.05-8 mm is more preferable. When the diameter of the bubbles is less than 0.01 mm, the effect of improving the feeling of use such as ease of spreading and the effect of the soluble gas itself tend to be difficult to obtain. In addition, when the diameter exceeds 10 mm, the bubbles are naturally easily broken at the time of application, so that it is difficult to obtain the effect of improving the feeling of use and the effect of the soluble gas itself. The shape of the bubble is not particularly limited, and may be a spherical shape close to a true sphere or a shape close to a spheroid, but the bubble diameter in the present invention is the maximum bubble diameter. .

  The production method of the coating composition of the present invention is not particularly limited, and a known method can be adopted. However, it is possible to more efficiently disperse a small amount of dissolved gas bubbles in a viscous material. From the above, the production method includes a dissolving step of dissolving a soluble gas in a viscous material under a high-pressure condition or a low-temperature condition of atmospheric pressure or higher, and a bubbling step of bubbling the soluble gas dissolved by depressurization or elevated temperature. It is preferable. In addition, the coating composition obtained by this production method has the feature that the bubbles of the dispersed dissolved gas are smaller than the true sphere and smaller than those produced by other methods, It is also preferable from the viewpoint that the appearance beauty is further improved.

  As a dissolution process for dissolving a soluble gas in a viscous material under high-pressure conditions, the viscous gas is introduced into a pressure tank filled with a desired soluble gas to be dissolved, or after introducing the viscous material. The pressure tank can be filled with a desired soluble gas to obtain a high-pressure condition, and then a dissolution process can be performed in which the soluble gas is dissolved in a viscous material using a mixer or a porous material. Further, the soluble gas may be dissolved while the viscous material is cooled. In addition, before performing the dissolution process, by vacuuming the air in the pressure tank and reducing the pressure, by performing a deaeration process of discharging air bubbles contained in the viscous material and dissolved air, Only the soluble gas can be efficiently dissolved in the viscous material.

  The solubility of the soluble gas in the liquid (viscous material) depends on the pressure, and the higher the pressure condition, the higher the solubility. Therefore, by performing the dissolution process to dissolve the soluble gas in the viscous material under the high pressure condition, the atmospheric pressure condition It is possible to dissolve a large amount of soluble gas above the saturated dissolution amount below in the viscous material. Therefore, by reducing the saturated dissolution amount of the soluble gas in the viscous material by reducing the pressure such that the obtained coating composition is at atmospheric pressure, the dissolution that exceeds the saturated dissolution amount after the reduced pressure It can be set as the bubbling process which generate | occur | produces property gas as a bubble (bubble generation). Note that the dissolved gas is saturated and dissolved in the viscous material after decompression. In addition, the size and amount of bubbles generated can be controlled by adjusting the pressure and temperature in the dissolution process, that is, adjusting the dissolution amount of the soluble gas. Furthermore, by disperse | distributing soluble gas in a viscous material under high pressure conditions, it can be expanded by pressure reduction and it can be set as the bubble of a desired magnitude | size.

  The pressure condition in the melting step is preferably a pressure condition higher by 0.01 to 1.0 MPa than atmospheric pressure (0.1 MPa), and more preferably a pressure condition higher by 0.03 to 0.8 MPa. When the difference from the atmospheric pressure is less than 0.01 MPa, the pressure difference is small, and there is a tendency that the effect of dissolving the soluble gas quickly and the effect of reducing the pressure to form bubbles are difficult to obtain. On the other hand, when the difference from the atmospheric pressure exceeds 1.0 MPa, the bubbles become rough and the coating tends to be difficult.

  Here, in the case where a viscous material containing gelatin is used as the water-soluble polymer, the dissolving step is performed in a state where the viscous material has fluidity, so that the soluble gas is easily dissolved in the viscous material. be able to. Then, by performing the bubbling step by reduced pressure as in the case described above, it is possible to generate (bubble) the dissolved gas dissolved in excess of the saturation dissolution amount after the reduced pressure. The coating composition (containing gelatin) obtained by the dissolution step may be subjected to an aeration step in a state where there is no fluidity. However, the foaming step is performed in a fluid state from the viewpoint of being easily aerated. It is preferable. In addition, when the viscosity of the viscous material is increased by storing in a low temperature state before the bubble forming step, the bubble forming step may be performed after heating to return to a fluid state. Furthermore, after the foaming step is performed in a state where the viscous material has fluidity, the retention property of the bubbles can be improved by increasing the viscosity of the viscous material by lowering the temperature of the obtained coating composition.

  In addition, the dissolution process for dissolving the soluble gas in the viscous material under a low temperature condition may be a dissolution process in which the soluble gas is dissolved in the viscous material at a low temperature by stirring with a mixer or using a porous material. it can.

  Since the solubility of the soluble gas in the liquid (viscous material) depends on the temperature, and the solubility becomes higher as the temperature is lower, the step of dissolving the soluble gas in the viscous material at a temperature lower than normal temperature (25 ° C) is performed. By this, a large amount of soluble gas more than the saturated dissolution amount at 25 ° C. can be dissolved in the viscous material. Therefore, by dissolving the dissolved composition in excess of the saturated dissolved amount after the temperature increase by lowering the saturated dissolved amount of the soluble gas in the viscous material by increasing the temperature such as bringing the obtained coating composition to room temperature. It can be set as the bubbling process which generate | occur | produces property gas as a bubble (bubble generation). In this case as well, the soluble gas is saturated and dissolved in the viscous material after the temperature rise. Moreover, the soluble gas disperse | distributed on low temperature conditions can also be made into the bubble of a desired magnitude | size by expanding by temperature rising.

  0-15 degreeC is preferable and, as for the low temperature conditions in the said melt | dissolution process, 1-10 degreeC is more preferable. When the temperature is lower than 0 ° C., the viscous material tends to solidify, the viscosity of the viscous material increases, or the soluble gas tends to hardly dissolve. Moreover, when it exceeds 15 degreeC, there exists a tendency for the effect which dissolves soluble gas quickly, and the effect which raises temperature and is made into a bubble become difficult to be acquired.

  In any dissolution process, after the dissolution process, the gas containing the soluble gas that is not dissolved in the viscous material and remains in the gas phase in the tank or the like is dispersed as fine bubbles in the viscous material. By performing the bubble formation process after that, the bubbles become the core and new bubbles are easily generated in the bubble formation process, and a large amount of fine bubbles can be dispersed in the viscous material.

  The coated product of the present invention can be produced by filling a container with the coating composition. Although it does not specifically limit as a shape of a container, A tube container, a pouch container, a resin bottle, a jar container, an aerosol container, etc. are mentioned, It can select suitably according to the use and objective of a coated product. In addition, the coating composition of the present invention, which is the content, can produce an external beauty due to the bubbles containing the soluble gas dispersed in the viscous material, so that the content can be visually recognized from the outside. It is preferable to use a light-transmitting container. Examples of the light-transmitting container include a container made of a synthetic resin such as glass, polyethylene terephthalate, and polyethylene. These containers may be provided with valves.

  Application obtained by a production method including the above-described dissolving step of dissolving a soluble gas in a viscous material under high-pressure or low-temperature conditions, and the bubbling step of bubbling the soluble gas dissolved by depressurization or elevated temperature The composition for use can also be made into a coated product by filling the container after the bubble forming step.

  In addition, in the case of a production method including a dissolving step of dissolving a soluble gas under high pressure conditions, the coating composition in which the soluble gas is dissolved is placed in a container with a valve that can be sealed such as a pressure resistant container under high pressure conditions. By filling, the pressure inside the container is lowered by opening the valve at the time of use, and it is possible to produce a moving beauty that the soluble gas in the coating composition is bubbled. In this case, unsealing at the time of use is a bubble forming step for forming a dissolved gas dissolved by decompression into bubbles. In addition, when filling a container having pressure resistance (such as an aerosol container), the dissolving step and the bubble forming step can be performed in one container. Here, examples of the container that can reduce the internal pressure during use include a pressure-resistant container equipped with a valve that can be opened and closed from the outside.

  Examples of the material of the pressure-resistant container include metals such as aluminum and tin, synthetic resins such as polyethylene terephthalate, and glass. Moreover, it is good also as an aerosol container of the double structure of inserting an inner bag in the container which has these pressure | voltage resistance, and the outer container which has pressure | voltage resistance, and the flexible inner container (volume variable inner container). These aerosol containers can be appropriately selected according to the properties and application of the coating composition. A double-structure aerosol container having a variable volume inner container and an outer container is preferable from the viewpoint that it is easy to discharge all of the filled coating composition.

  As the outer container of the double-layered aerosol container, a one-piece type metal container in which disk-shaped aluminum is formed into a bottomed cylindrical shape by impact molding, drawing or ironing, etc., a metal plate such as tinplate is made cylindrical. A three-piece type metal container with a metal base and bottom wound around the top and bottom openings, and a resin container molded into a bottomed cylinder by biaxial stretch blow molding using a synthetic resin such as polyethylene terephthalate And a container having pressure resistance, such as a glass container. As described above, it is preferable that the container has translucency so that the contents can be visually recognized from the outside.

  Moreover, as said inner container of variable volume, synthetic resins, such as polyolefins, such as flexible polyethylene (PE) and polypropylene (PP), ethylene-vinyl alcohol copolymer (EvOH), and nylon (NY), are used. Then, it is molded into a bottomed cylinder by direct blow molding or the like, and can have a single layer structure of the synthetic resin or a laminated structure such as PE / EvOH / PE, PE / NY / PE. One or a plurality of sheets may be welded or adhered to form a pouch-type bag. Examples of the sheet include synthetic resin sheets such as polyethylene, polyethylene terephthalate, nylon, and eval. In particular, when filling the inner container with a viscous substance, filling the soluble gas between the inner container and the outer container, and allowing the soluble gas to permeate through the inner container and dissolve in the viscous substance, polyethylene, polypropylene It is preferable to use an inner container of a single layer structure made of a synthetic resin having a high permeability of a soluble gas such as nylon or polyethylene terephthalate (easy to permeate).

  The manufacturing method which performs a melt | dissolution process and an aeration process in an aerosol container is demonstrated.

  When a viscous material and a soluble gas are filled into the container using an aerosol container, the dissolution process is performed under the above-described pressure condition in the container filled with the viscous material and the soluble gas. It can be set as the process of dissolving sex gas. The bubble forming step can be a step of decompressing the inside of the container by opening a valve (aerosol valve) that can be opened and closed from the outside.

  Next, referring to the attached drawings, a manufacturing method in the case where a double structure aerosol container is used, the viscous material is filled in the inner container, and the soluble gas is filled between the inner container and the outer container. Although described, it is not limited to this mode.

  This manufacturing method includes a filling step, a dissolving step, and an aeration step. In the filling step, after the viscous material is filled in the inner container 2, the space between the outer container 1 and the inner container 2 is filled with the soluble gas 5, and the opening of the outer container 1 is fixed by the aerosol valve 3. This can be a process (FIG. 1A). In the dissolution step, the soluble gas in the space between the outer container 1 and the inner container 2 is permeated into the inner container 2 by standing or shaking for a predetermined time, and the viscous material 4 in the inner container 2 is passed through. It can be set as the melt | dissolution process which dissolves a soluble gas in saturation (FIG.1 (b)). Here, since the filled soluble gas permeates through the inner container and the equilibrium pressure is obtained in the inner container and between the inner container and the outer container, the soluble gas is adjusted so that the equilibrium pressure becomes the aforementioned pressure condition. Is preferably filled. Then, after the soluble gas remaining in the gas phase portion 6 in the inner container 2 is dispersed in a viscous material by shaking the container up and down, etc., a valve (aerosol valve 3) that can be opened and closed from the outside By releasing the pressure, the pressure in the inner container is reduced to lower the saturated dissolution amount, and a bubble forming step can be performed in which the soluble gas dissolved in the viscous material is generated as bubbles 7 (FIG. 1 (c) )).

  In the above-described filling step, the inner container is not filled with a viscous substance, but the space between the outer container and the inner container is filled with a soluble gas, and the opening of the outer container is fixed with an aerosol valve, Next, after the aerosol valve is opened and the air in the inner container is discharged, by filling the viscous material from the aerosol valve, only the soluble gas can be efficiently dissolved in the viscous material.

  On the other hand, in the case of a coating composition obtained by a dissolution process that dissolves under low temperature conditions, the low temperature conditions are maintained until use, and the soluble gas in the coating composition is bubbled by increasing the temperature during use. It is possible to produce beauty with the movement of becoming. In this case, raising the temperature at the time of use is a bubble forming step for bubbling the dissolved gas dissolved by the temperature rise.

  The coated product of the present invention is a coated product having not only an improvement in appearance beauty but also an effect due to viscous substances and an effect due to bubbles of soluble gas. Therefore, the hair styling agent, shampoo, conditioner, cleansing, hair restorer It can be suitably used for products used on the skin such as scalp / hair products, anti-inflammatory analgesics, antipruritics, antiperspirants, astringents, moisturizers, anti-hot flashes and the like.
