Description

  The present invention relates to a two-component mixed skin care agent containing magnetic powder and cosmetic ingredients.

  As a skin care agent used for skin beautification, there is one that removes dirt, wastes and the like together with a skin care agent by removing it after a while after being applied to the skin. As a method of removing such a skin care agent from the skin, a method of wiping with cotton or the like, or washing off with warm water or the like is common. Recently, a method for removing a used skin care agent more easily than these general methods has been desired.

  For example, Patent Document 1 describes a pack agent containing a coated iron powder. By blending iron powder in the pack agent, the pack agent after use can be easily removed from the applied skin by magnetic force, and skin dirt and waste products can be removed together with the pack agent. .

  In addition, after performing the work of removing dirt on the skin using a pack agent, cosmetic ingredients such as nutritional ingredients for replenishing nutrients to the skin and whitening ingredients for imparting a whitening effect are infiltrated into the skin. Obtaining a cosmetic effect by a cosmetic ingredient is also effective for skin beauty.

JP 2004-155720 A

  The magnetic powder contained in the skin care agent applied to the skin can be easily adsorbed and removed from the skin surface as the magnetic force acting on the entire magnetic powder increases. Therefore, from the viewpoint of increasing the magnetic force acting on the entire magnetic powder, it is preferable to use iron powder or black iron oxide having a large magnetization as the magnetic powder. However, the skin care agent containing iron powder or black iron oxide has a problem in that the scent at the beginning of production changes with time, resulting in an unpleasant odor as a skin care agent.

  This phenomenon is considered to occur due to the following causes, for example. Metallic iron, the main component of iron powder, is easily oxidized. Magnetite, which is the main component of black iron oxide, is a mixed valence compound containing both divalent iron and trivalent iron, so that the oxidation number of iron is increased by contact with an oxidizing agent or a reducing agent. Can change. Thus, it is thought that the surface of the particle | grains which comprise iron powder and black iron oxide is in the state which a chemical reaction tends to occur. And when the reactivity of the particle surface is high, cosmetic ingredients, oil components and fragrances contained in the skin care agent are brought into contact with the particles and deteriorated, or fragrances are adsorbed on the surface of the particles, etc. It is thought that a phenomenon occurs, which in turn changes the scent of the skin care agent.

  In addition, magnetic powder containing metallic iron and magnetite has a problem that it is oxidized and rusted by moisture contained in the skin care agent in advance, moisture in the atmosphere absorbed by the skin care agent, and the like. The magnetic powder that has been oxidized until rust is produced has a deteriorated magnetic property, so that it is difficult to remove it from the skin. Further, the rust of the magnetic powder is not preferable in terms of appearance when used in a skin care agent.

  As a countermeasure against the above-mentioned scent alteration of the skin care agent and generation of rust, there is a method of coating the surface of the magnetic powder as disclosed in Patent Document 1, for example. However, when coating magnetic substance powder, there exists a problem of causing the cost increase of the whole skin care agent.

  The present invention has been made in view of such a background, and an object of the present invention is to provide a skin care agent that can maintain quality over a long period of time at low cost.

One aspect of the present invention is a two-component mixed skin care agent used by mixing a first agent composed of a magnetic powder-containing agent and a second agent composed of a liquid agent,
The skin care agent contains cosmetic ingredients and is configured to be able to adsorb and remove magnetic powder from the applied skin by magnetic force.
The first agent includes the magnetic powder having a volume average particle size of 20 to 150 μm determined from a particle size distribution obtained by a laser diffraction / scattering method, and exhibits a powder form.
The cosmetic ingredient is contained in at least one of the first agent and the second agent, and is in a two-component mixed skin care agent.

  The two-component mixed skin care agent (hereinafter referred to as “skin care agent” as appropriate) is configured to be used by mixing the first agent and the second agent. That is, the first agent and the second agent are stored separately, and the skin care agent is prepared by mixing the first agent and the second agent before use. Therefore, the magnetic substance powder contained in the first agent and the second agent do not come into direct contact during storage. Also, for example, by producing the necessary amount of the skin care agent every time it is used, the time during which the magnetic substance powder and the second agent are in direct contact can be sufficiently shortened. As a result, it is possible to prevent the scent of the skin care agent from changing in quality and the occurrence of rust.

  Moreover, since the time for which the magnetic substance powder and the second agent are in direct contact can be sufficiently shortened, it is not necessary to coat the surface of the magnetic substance powder. Therefore, the cost of the skin care agent is easy.

  Moreover, since the said 1st agent is exhibiting the powder form, the quality change of the said 1st agent can be suppressed over a long period of time.

  The magnetic powder has a volume average particle size in the specific range. Therefore, the first agent and the second agent can be easily mixed. Moreover, by having the volume average particle diameter in the specific range, when a magnet or the like is brought close to the magnetic powder, the magnetic force acting on the whole magnetic powder tends to increase. As a result, the magnetic powder can be easily adsorbed and removed from the skin surface by a magnetic force together with the used skin care agent and skin dirt.

  As described above, the skin care agent can maintain the quality over a long period of time at a low cost.

  The skin care agent may be configured such that at least part of the skin powder remains on the skin surface when the magnetic powder is adsorbed and removed from the skin by magnetic force, depending on the cosmetic effect to be obtained. Accordingly, almost all may be removed from the skin surface.

  As cosmetic ingredients contained in the skin care agent, for example, whitening ingredients such as ascorbic acid derivatives, kojic acid, arbutin, tranexamic acid, nutritional ingredients such as amino acids, vitamins, plant extracts, microbial fermentation products, and moisturizing ingredients, Cosmetic ingredients that give skin a cosmetic effect can be used. The beauty component may be contained alone, or a plurality of components may be used in combination.

  From the viewpoint of preventing the quality change caused by contact with the magnetic powder, it is necessary to add a liquid cosmetic component to the second agent. On the other hand, the powdery cosmetic ingredient may be blended with the first agent or the second agent.

  Moreover, it is preferable that the skin care agent contains 15-80 mass% magnetic substance powder and the said 2nd agent of 20-85 mass%. In this case, since the amount of the magnetic powder contained in the skin care agent applied to the skin is relatively large, the magnetic force acting on the entire magnetic powder increases when a magnet or the like is brought closer. Therefore, the used skin care agent can be more easily adsorbed and removed from the skin surface together with the skin dirt and the like, and the remaining skin care agent etc. on the skin surface can be prevented.

  When the content of the magnetic substance powder is less than 15% by mass or when the content of the second agent exceeds 85% by mass, the content of the magnetic substance powder is small. There is a possibility that the magnetic force acting on the whole powder becomes insufficient. Therefore, it becomes difficult to adsorb and remove the used skin care agent from the skin surface. Therefore, from the viewpoint of facilitating adsorption and removal of the skin care agent from the skin surface, the content of the magnetic powder is preferably 15% by mass or more, more preferably 30% by mass or more, and further preferably 50% by mass or more. Similarly, the content of the second agent is preferably 85% by mass or less, and more preferably 70% by mass or less.

  On the other hand, when the content of the magnetic substance powder exceeds 80% by mass or when the second agent is less than 20% by mass, the second agent is insufficient, so that the skin care agent may exhibit a sticky lump. is there. Therefore, it may be difficult to spread the skin care agent on the skin. Therefore, in order to obtain a skin care agent having properties suitable for application to the skin, the content of the magnetic powder is preferably 80% by mass or less, more preferably 75% by mass or less, and 70% by mass or less. Further preferred. Similarly, the content of the second agent is preferably 20% by mass or more, and more preferably 25% by mass or more.

  Moreover, it is preferable that the said 1st agent and the said 2nd agent are packaged for every predetermined usage-amount. The “predetermined usage amount” may be a single usage amount or a multiple usage amount. In this case, the mixing ratio of the first agent and the second agent can be adjusted to an appropriate ratio without measuring the first agent and the second agent. Therefore, a skin care agent can be produced more easily. In this case, it is easy to block the first agent and the second agent from the outside air until the package is opened. Therefore, the quality of the first agent and the second agent can be maintained for a longer period of time, and the skin care agent can be stored for a longer period of time. In addition, as said packaging, conventionally well-known forms, such as an aluminum pouch and a small bottle, are employable, for example.

  In the above-mentioned case, it is more preferable that the first agent and the second agent are packaged in such an amount that they can be used up before the skin care agent is deteriorated. It is particularly preferable. In this case, alteration of the skin care agent can be reliably prevented. The amount of the skin care agent to be used can be appropriately set according to the use. For example, when the skin care agent is configured for the face, the amount of use for one use can be usually set within a range of 1 to 20 g. Moreover, when the skin care agent is comprised for whole body, the usage-amount for 1 time can be normally set within the range of 400-600g.

  In addition, the skin care agent after 10 seconds when the glass plate was tilted at an angle of 60 ° with respect to the horizontal plane in a state where 1 g of skin care agent was applied in a disk shape having a diameter of 2 cm on a glass plate having a smooth surface. The skin care agent may be configured so that the moving distance is 2 cm or less. In this case, since the skin care agent has an appropriate viscosity, it is excellent in ease of spreading at the time of application, can be prevented from dripping from the applied skin, and has more suitable properties for application to the skin. In this case, the skin care agent exhibits a smooth touch. Adjustment of the movement distance mentioned above can be performed by adjustment of content of the said magnetic body powder, adjustment of the viscosity of the said 2nd agent, etc., for example.

  In addition, when the skin care agent has a moving distance in the specific range, the state where the magnetic powder is dispersed in the skin care agent can be maintained for a long time. Therefore, it is possible to more easily realize a state in which a sufficient amount of magnetic powder for adsorption removal is contained in the skin care agent applied to the skin surface. As a result, the magnetic powder and the used skin care agent can be more easily adsorbed and removed from the skin surface, and the remaining of the used skin care agent and fine particles in the magnetic powder on the skin surface is further suppressed. it can.

  Below, the said 1st agent and the said 2nd agent are demonstrated in detail.

(First agent)
The first agent is made of a magnetic powder-containing agent that essentially contains magnetic powder and has a powder form. The magnetic powder-containing agent may be composed only of magnetic powder, and may further contain a powdery component. Said powdery component has the property which is hard to change even if it contacts with a magnetic substance powder compared with the component which exhibits liquid state. Therefore, even when the powdery component is blended with the first agent, the alteration of the first agent can be suppressed over a long period of time. As a powdery component mentioned above, the beauty component which exhibits a powdery form can be mix | blended, for example. Moreover, the said 1st agent may contain the powdery additives normally used for cosmetics, such as a thickener, surfactant, and a bulking agent.

  The magnetic powder is preferably composed of a ferromagnetic material. In this case, the magnetic force acting on the entire magnetic powder becomes large when a magnet or the like is brought close. For this reason, magnetic powder and the like can be easily adsorbed and removed from the skin surface. Examples of the ferromagnetic material include simple metals of iron, nickel, and cobalt, and alloys containing at least one element among these metal elements. In general, these single metals and alloys may contain other chemical components such as inevitable impurities.

  Further, the magnetic powder may contain a ferrite exhibiting ferromagnetism as a main component. Here, the “main component” indicates that the chemical component has the highest content. That is, the magnetic powder in this case usually contains iron-based oxides having different degrees of oxidation, such as wustite and hematite, inevitable impurities, etc., in addition to ferrite exhibiting ferromagnetism as a main component.

As the ferrite exhibiting ferromagnetism, spinel type ferrite, magnetoplumbite type ferrite, garnet type ferrite, perovskite type ferrite and the like can be used. Among these ferrites, it is preferable that soft ferrite having high saturation magnetization and low both residual magnetization and coercive force as a main component. Specific examples of soft ferrite include (MO) _x (Fe ₂ O ₃ ) _y (where x + y = 100 mol%, and M is Fe, Mn, Mg, Sr, Ca, Ba, Cu, Zn, Ni, Li And one or more elements selected from metal elements such as Co.) and a spinel ferrite having a composition formula. Of the spinel ferrites, it is more preferable to use a ferrite having high saturation magnetization.

On the other hand, it is preferable that the magnetic powder used for the skin care agent has fewer kinds of constituent elements. Therefore, when ferrite is used in the central part of the magnetic powder, magnetite (Fe ₃ O ₄ ) having high saturation magnetization and composed of two kinds of elements of Fe and O is used as the ferrite. More preferably.

  The magnetic powder has a volume average particle size of 20 to 150 μm determined from the particle size distribution obtained by the laser diffraction scattering method.

  The volume average particle diameter is calculated as the cumulative 50% particle diameter (median diameter) obtained by the volume distribution mode and the display under the sieve in the particle size distribution obtained by the laser diffraction scattering method.

  When the volume average particle size is less than 20 μm, the particle size distribution of the magnetic powder tends to be a distribution in which the content of particles having an excessively small particle size is large. The magnetic force acting on individual particles becomes weaker as the particle size is smaller. Therefore, when many particles having an excessively small particle diameter are contained, the magnetic force acting on the entire magnetic powder tends to be weak. As a result, adsorption removal from the skin such as magnetic powder and used skin care agent becomes difficult, and in some cases, these may remain on the skin surface.

  On the other hand, when the volume average particle size exceeds 150 μm, the particle size distribution of the magnetic powder tends to be a particle size distribution with a large content of particles having an excessively large particle size. Therefore, in this case, there is a possibility that the feeling of use is deteriorated, for example, the skin care agent has a poor touch.

  Therefore, the volume average particle size of the magnetic powder is set to 20 to 150 μm from the viewpoint of achieving both adsorption and removability of the magnetic powder and usability. From the same viewpoint, the volume average particle size of the magnetic powder is more preferably 50 to 75 μm.

Moreover, it is preferable that the said 1st agent contains the magnetic body powder whose saturation magnetization is 70 Am < ² > / kg or more. In this case, the magnetic force acting on the entire magnetic powder tends to be larger. As a result, the magnetic powder can be more easily adsorbed and removed from the skin. From the same viewpoint, the saturation magnetization of the magnetic powder is more preferably 80 Am ² / kg or more.

(Second agent)
The second agent is composed of a liquid agent.

  The “liquid” includes, for example, a low viscosity such as water, a syrup having a medium viscosity, and a paste having a relatively high viscosity. In addition, as the second agent, one having a lower viscosity or higher viscosity than the above-described range may be used. The viscosity of the second agent can be appropriately selected so as to achieve the desired characteristics such as the feeling of use of the skin care agent, that is, the touch and the ease of elongation during application. Moreover, magnetic powder becomes easy to disperse | distribute in the said 2nd agent by selecting the viscosity of the said 2nd agent appropriately. As a result, the skin care agent tends to have properties suitable for application to the skin.

  When the second agent is oil-based, for example, the viscosity of the second agent can be easily adjusted by using oil components having different viscosities as appropriate. That is, in order to increase the viscosity of the second agent, the content of the high viscosity oil component may be increased. Moreover, what is necessary is just to increase content of a low-viscosity oil type component, when making the viscosity of the said 2nd agent low. On the other hand, when the second agent is aqueous, the viscosity of the second agent can be adjusted by using a thickener.

  Moreover, when the said 2nd agent is aqueous type | system | group, adhesiveness can be provided between the particles which comprise magnetic body powder in skin care agent by presence of a thickener. For this reason, skin care agents containing thickeners tend to adhere magnetic particles to each other when the skin care agent is applied to the skin, and the used skin care agent is peeled off from the skin surface in a continuous state. It becomes easy. As a result, the skin care agent can be easily adsorbed and removed from the skin surface, and the remaining skin care agent and fine particles in the magnetic powder on the skin surface can be suppressed.

  Examples of thickeners include glycerin, (acrylates / alkyl acrylate (C10-30)) crosspolymer, cellulose derivatives, xanthan gum, guar gum, starch and derivatives thereof, alginate and derivatives thereof, agar, sodium polyacrylate, Conventionally known thickeners for cosmetics such as carboxyvinyl polymer and bentonite can be used. These thickeners may be used independently and may use multiple types together. Usually, the thickener is blended with the second agent, but the thickener exhibiting a powder form can be blended with the first agent.

  The above-mentioned “oil-based” is composed of components (oil-based components) in which 50% by mass or more does not dissolve in water when the total of each component contained in the second agent is 100% by mass. It means being. The term “aqueous” means that 50% by mass or more is composed of water and / or water-soluble components when the total of the components contained in the second agent is 100% by mass.

  The second agent is 10 when the glass plate is inclined at an angle of 60 ° with respect to a horizontal plane in a state where 1 g of the second agent is applied in a disk shape having a diameter of 2 cm to a glass plate having a smooth surface. The moving distance of the second agent after 2 seconds is preferably 4 cm or less. In this case, since the second agent has a reasonably large viscosity, the magnetic powder can be easily dispersed when mixed with the first agent. Moreover, in this case, since the viscosity of the obtained skin care agent becomes moderately large, it is excellent in touch and ease of elongation at the time of application, and can be prevented from dripping from the applied skin. Therefore, the skin care agent can be more easily produced, and the obtained skin care agent has more excellent performance. From the same viewpoint, the movement distance of the second agent described above is more preferably 2 cm or less.

  The second agent is preferably aqueous. That is, the second agent preferably has a total content of water and water-soluble components of 50% by mass or more. In this case, after the used skin care agent is adsorbed and removed by magnetic force, there are few oil-based components remaining on the skin surface, so that the formation of an oil film that inhibits the penetration of beauty components and the like into the skin is suppressed. Therefore, after the skin care agent is adsorbed and removed from the skin surface, the user can use the skin lotion or the like as it is, and it is not necessary to separately perform a face wash or the like for removing the oil film before using the skin lotion or the like. As a result, the skin care agent simplifies the work for obtaining a cosmetic effect. From the viewpoint of suppressing the formation of an oil film on the skin surface, the total content of water and water-soluble components is preferably 60% by mass or more, and more preferably 70% by mass or more.

  In the case where the second agent is water-based, it may be configured such that water is not blended, but water may be blended in the second agent so as to be 5 to 73% by mass with respect to the entire skin care agent. . When the amount of water is within the specific range, the skin care agent tends to be a smooth paste in which magnetic powder is dispersed. Therefore, when applied to the skin, the skin care agent is easy to spread and exhibits a smoother touch.

  When the blending amount of water is less than 5% by mass, the resulting skin care agent may exhibit a sticky lump because water is insufficient. Further, in this case, the skin care agent is likely to feel bad when it is brought into contact with the skin or the like, and in some cases, the skin care agent may give an excessively large stimulus to the skin. Therefore, it may be difficult to spread the skin care agent on the skin. Therefore, from the viewpoint of obtaining a skin care agent exhibiting properties suitable for application to the skin, the amount of water is preferably 5% by mass or more, and more preferably 6% by mass or more.

  On the other hand, when the amount of water exceeds 73% by mass, the amount of magnetic powder becomes insufficient, which may result in insufficient magnetic force acting on the entire magnetic powder when a magnet or the like is brought close thereto. There is. Therefore, in some cases, a used skin care agent or the like may remain on the skin surface. Further, in this case, there is a possibility that problems such as the skin care agent dripping from the skin surface due to low viscosity may occur. Therefore, from the viewpoint of obtaining a skin care agent having a moderately large viscosity, the amount of water is preferably 73% by mass or less, more preferably 30% by mass or less, and even more preferably 15% by mass or less.

  When the second agent is aqueous, it is preferable that at least one of the first agent or the second agent contains an iontophoretic component that dissolves in water and ionizes as the cosmetic component. . In this case, after the used skin care agent is adsorbed and removed from the skin surface, the iontophoretic component remains on the skin surface. The iontophoretic component remaining on the skin is ionized by the moisture contained in the skin itself and the moisture contained in the skin care agent, so that a weak current flows through the skin to move the iontophoretic component toward the inside of the skin, and beauty. The penetration of the ingredients into the skin can be promoted. As a result, a more excellent cosmetic effect can be obtained.

  Further, the skin care agent preferably has a conductivity at 25 ° C. of 20 μS / cm or more. In this case, since a weak current for allowing the iontophoretic component to penetrate into the skin is likely to flow, iontophoresis can be reliably performed. As a result, a more excellent cosmetic effect can be obtained.

(Other additives)
The skin care agent may further contain additives usually used in cosmetics in addition to the above-described components. Examples of the additive include a lubricant, an antibacterial agent, a fragrance, an extender, a pigment, and a pH adjuster. These additives can be appropriately added as long as the effects of the present invention are not impaired.

  Similar to the cosmetic ingredients, the additive can be selected to be blended with the first agent or the second agent according to the properties. In other words, powdery additives such as talc, kaolin, and dextran may be included in the first agent or may be included in the second agent. On the other hand, liquid additives such as dimethicone and essential oil need to be added to the second agent from the viewpoint of preventing deterioration due to contact with the first agent.

  Moreover, it is preferable that at least one of the first agent or the second agent contains a thixotropic agent that imparts thixotropic properties. The skin care agent to which thixotropy is imparted has a reduced viscosity of the skin care agent when the skin care agent is flowing, such as when applied to the skin. In addition, after the application to the skin is completed, the flow of the skin care agent stops, so that the viscosity increases. Therefore, the skin care agent containing a thixotropic agent can easily mix the first agent and the second agent. Moreover, the skin care agent containing a thixotropic agent has a viscosity suitable for application at the time of application to the skin, and is difficult to sag from the skin when the application is completed. As a result, the skin care agent can be used more easily.

  As the thixotropic agent, conventionally known thixotropic agents are used for cosmetics such as bentonite, 12-hydroxystearic acid, crystalline cellulose and the like.

  The skin care agent may contain a surfactant in at least one of the first agent and the second agent. The surfactant has an action of dispersing the magnetic powder in the skin care agent. Therefore, the skin care agent containing a surfactant can more reliably realize a state in which the magnetic powder is dispersed. As a result, the skin care agent exhibits a smooth paste shape and a smoother touch.

  Examples of the surfactant include coconut oil fatty acid PEG-7 glyceryl, polyglyceryl-10 laurate, alkyl sulfate ester salt, acylamino acid salt, polyoxyethylene alkyl ether sulfate, alkyl ether phosphate ester salt, alkyl polyethylene glycol ether Conventionally known surfactants for cosmetics such as glycerin polypropylene glycol ether, alkyl polyglycerin ether, and ethylene oxide / propylene oxide block copolymer can be used. These surfactants may be used alone or in combination of two or more.

Example 1
Examples of the two-component mixed skin care agent (hereinafter referred to as “skin care agent” where appropriate) will be described. As shown in FIG. 1, the skin care agent 1 is configured to use a mixture of a first agent 2 made of a magnetic powder-containing agent and a second agent 3 made of a liquid agent. As shown in FIG. 2, the skin care agent 1 contains an iontophoretic component 31 as a cosmetic component, and is configured to be able to adsorb and remove the magnetic powder 21 from the applied skin 4 by magnetic force. The first agent 2 includes a magnetic powder 21 having a volume average particle size of 20 to 150 μm obtained from a particle size distribution obtained by a laser diffraction / scattering method, and is in a powder form. Hereinafter, the configuration of the skin care agent 1 will be described in detail according to the production method and the usage method. And the 2nd agent 3 is exhibiting the liquid state while containing a beauty component.

<Production method>
-Composition of the first agent 2 and the second agent 3 As the first agent 2, a commercially available iron powder having a volume average particle size of 80 μm was prepared. Moreover, each component was mixed according to the following composition ratio, and the 2nd agent 3 was prepared.

・ Water: 31.04% by mass
・ Thickener glycerin: 50.00 mass%
Sodium polyacrylate: 0.02% by mass
・ Thixotropic agent Bentonite: 0.30% by mass
-Surfactant polyglyceryl monolaurate: 0.40 mass%
・ Beauty ingredients (ion-introduced ingredient 31)
L-sodium ascorbate-2-phosphate: 0.20% by mass
・ Lubricant, pH adjuster, preservative, etc .: balance

  In addition, L-ascorbic acid-2-phosphate sodium contained as a cosmetic ingredient is dissolved in water in the second agent 3, and L-ascorbic acid-2-phosphate ion 311 (FIG. 2 (c)). See) and sodium ions. Moreover, L-ascorbic acid-2-phosphate ion 311 is a component which can anticipate the skin beauty effect by making it penetrate | infiltrate into the skin among the said 2 types of ions.

Preparation of skin care agent 1 As shown in FIG. 1A, a mixing container 51 having a cylindrical side surface 511 having a diameter of 2.5 cm and a bottom surface 512 having a spherical shape and bulging outward is prepared. The first agent 2 was weighed out. Next, the second agent 3 having the same mass as the first agent 2 is added to the mixing container 51, and the first agent 2 and the second agent 3 are stirred and mixed using a spatula 52 having an arcuate tip (FIG. 1). (B)). Stirring was continued for about 1 minute, and mixing was completed when it was judged that the color tone became uniform visually. The skin care agent 1 was obtained by the above (FIG.1 (c)).

-Usage method of skin care agent 1 As shown in Fig.2 (a), the skin care agent 1 was apply | coated to the skin surface 41 of the part which wants to obtain the beauty effect. The thickness of the skin care agent 1 at the time of application was such that the color of the skin 4 could not be seen through.

  After waiting a few minutes after applying the skin care agent 1 to the skin 4, as shown in FIG. 2B, the magnet 53 was brought close to the skin care agent 1 applied to the skin 4. Thereby, the magnetic powder 21 was attracted and removed from the skin surface 41 by a magnetic force. In addition to the magnetic powder 21, the used skin care agent 100 and the dirt 400 on the skin 4 attached to the magnetic powder 21 were removed from the skin surface 41 by adsorption. The magnet 53 used in this step may be a permanent magnet such as a ferrite magnet or a neodymium magnet, or may be an electromagnet.

  The skin care agent 1 of this example is configured such that the aqueous solution 11 containing the iontophoretic component 31 remains on the skin surface 41 after the used skin care agent 100 and the like are adsorbed and removed by magnetic force. The sodium L-ascorbate-2-phosphate that is the iontophoretic component 31 is ionized in the aqueous solution 11. Thereby, as shown in FIG. 2 (b), the skin care agent 1 is adsorbed and removed from the skin surface 41, and the aqueous solution 11 containing L-ascorbic acid-2-phosphate ions 311 is applied to the skin surface 41. It becomes a state.

  Thereafter, as shown in FIG. 2C, the working electrode 54 is brought into contact with the skin surface 41 in a state where the aqueous solution 11 containing L-ascorbic acid-2-phosphate ion 311 is applied, and the aqueous solution 11 is applied. The counter electrode 55 was brought into contact with the skin surface 411 where there was no skin. In this state, by applying a voltage between the working electrode 54 and the counter electrode 55, an ion introduction current was passed through the skin 4, and the L-ascorbic acid-2-phosphate ion 311 was permeated into the skin 4. Thus, the work for beauty using the skin care agent 1 was completed.

  Next, the function and effect of this example will be described. The skin care agent 1 is configured to use a mixture of the first agent 2 and the second agent 3. Therefore, the magnetic powder 21 contained in the first agent 2 and the second agent 3 do not come into direct contact during storage. Moreover, after mixing, time for the magnetic substance powder 21 and the 2nd agent 3 to contact directly can be shortened enough. As a result, it is possible to prevent the fragrance of the skin care agent 1 from changing in quality or the occurrence of rust.

  Moreover, since the time for which the magnetic substance powder 21 and the second agent 3 are in direct contact can be sufficiently shortened, it is not necessary to coat the surface of the magnetic substance powder 21. Therefore, the cost of the skin care agent 1 is easy.

  Moreover, the magnetic substance powder 21 has a volume average particle diameter in a specific range. Therefore, the magnetic powder 21 can be easily mixed with the second agent 3 and can be easily adsorbed and removed from the skin surface 41 together with the used skin care agent 100, the dirt 400 of the skin 4 and the like by a magnetic force.

  In this example, sodium L-ascorbate-2-phosphate is used as a cosmetic ingredient. In conventional one-part skin care agents, when ascorbic acid ions, ascorbic acid derivative ions, and the like coexist with iron powder, both react to generate active oxygen and promote the deterioration of the skin care agent. It was. On the other hand, such a problem can be suppressed by using a two-component mixed type composition in which the magnetic powder 21 and the cosmetic component are mixed before use as in this example, and ascorbic acid or the like is used as the cosmetic component. can do.

  As described above, the skin care agent 1 can maintain the quality over a long period of time at a low cost.

  In addition, in this example, although the example of the skin care agent 1 containing the iontophoretic component 31 was shown, it can replace with the iontophoretic component 31, and the structure containing the cosmetics component which exhibits another cosmetic effect is also possible. . Since the second agent 3 of this example is composed of 80% by mass or more of water and water-soluble components, as described above, after the used skin care agent 100 and the like are adsorbed and removed by magnetic force, Forms almost no oil film that inhibits penetration of cosmetic ingredients. Therefore, after the skin care agent 1 is adsorbed and removed from the skin surface 41, the cosmetic ingredients are likely to penetrate into the skin 4, and a sufficient cosmetic effect can be expected.

(Experimental example)
In this example, the compositions of the first agent 2 and the second agent 3 were changed to various ratios shown in Table 1, and skin care agents 1 (test agent 1 to test agent 12) were produced. The magnetic powder 21 used for the first agent 2 is as follows.

Iron powder A commercially available iron powder having a volume average particle size of 80 μm was used. The saturation magnetization of the iron powder was about 180 Am ² / kg.
Black iron oxide powder Commercially available black iron oxide powder having a volume average particle size of 70 μm was used. The saturation magnetization of the black iron oxide powder was about 85 Am ² / kg.

  Moreover, the following evaluation was performed using the 1st agent 2, the 2nd agent 3, and the skin care agent 1 which are shown in Table 1.

<Drip test>
As shown in FIG. 3, 1 g of the second agent 3 was applied in a disk shape having a diameter of 2 cm on the glass plate 6 having a smooth surface (FIG. 3A). Next, the glass plate 6 was tilted at an angle of 60 ° with respect to the horizontal plane 61, and the second agent 3 was caused to flow along the slope of the glass plate 6 (FIG. 3B, arrow 601). And 10 seconds after tilting the glass plate 6 to 60 °, the tilt of the glass plate 6 was returned, and the flow of the second agent 3 was stopped. In this state, as shown in FIG. 3C, the distance d by which the tip 302 of the second agent 3 moved was measured with reference to the position 301 at the time of application. The value of the distance d obtained as described above is shown in the “movement distance of the second agent 3” column in Table 1.

  In addition, the skin care agent 1 was used in place of the second agent 3, and a dripping test was conducted in the same manner as described above. As a result, the value of the obtained distance d is shown in the “movement distance of skin care agent 1” column in Table 1.

Next, 5 g of the first agent 2 was added to the screw bottle, and the first agent 2 and the second agent 3 were stirred and mixed using a metal spatula having a rectangular shape with a tip of 7 mm in width. The ease of dispersion of the first agent 2 was evaluated based on the time until the color tone of the mixture of the first agent 2 and the second agent 3 became uniform. The results are shown in Table 1. In addition, symbols A to C shown in the column “Easy to Disperse” in Table 1 are symbols indicating the following results.

<Ease of applying skin care agent 1>
The ease of application when the skin care agent 1 was applied to the skin 4 was evaluated. The results are shown in Table 1. In addition, the symbols A to D shown in the column “Ease of applying skin care agent 1” in Table 1 are symbols indicating the following results.
A: The skin care agent 1 after application was held on the skin surface 41 and almost no dripping was observed. B: The skin care agent 1 after application had a slight tendency to sag from the skin surface 41. C: More than B Although the skin care agent 1 after application had a strong tendency to sag, it was at a level where there was no problem in use. D: The dripping of the skin care agent 1 was intense, and the state applied to the skin 4 could not be maintained.

<Easy to remove and remove skin care agent 1>
After applying the skin care agent 1 to the skin 4, it was allowed to stand for several minutes. Thereafter, the magnet 53 having a surface magnetic flux density of 2800 G was brought close to the skin care agent 1 applied to the skin 4. And the adsorption | suction state of the skin care agent 1 when the space | interval of the magnet 53 and the skin 4 reached about 10 mm was visually observed. The results are shown in Table 1. In addition, the symbol described in the column “Easiness of adsorption removal of skin care agent 1” in Table 1 is a symbol corresponding to the following state, respectively.
A: State in which skin care agent 1 does not remain on skin surface 41 B: State in which skin care agent 1 that remains granular on skin surface 41 is present in about two to three places C: A large amount of skin care agent 1 contains skin surface 41 State remaining in

  As is known from Table 1, the test agents 1 to 12 exhibited characteristics at a level that is not problematic for use in each evaluation item. In addition, Test Agent 2 to Test Agent 6 and Test Agents 8 to 12 in which the moving distance of the second agent 3 and the moving distance of the skin care agent 1 are 2 cm or less are almost free from dripping of the skin care agent 1 and excellent. The characteristics are shown. On the other hand, the test agent 1 and the test agent 7 having a moving distance of more than 2 cm are at a level that causes no problem in use, but there is a tendency for dripping to occur more easily than the test agents 2 to 6 and the like.

  As shown in FIG. 7, the bulging portion 721 includes a magnetic force generation surface 720 that is a flat surface, and a head side wall 722 that extends from the outer periphery of the magnetic force generation surface 720. As shown in FIG. 6, the magnetic force generation surface 720 has a substantially elliptical shape when viewed from below, and is arranged with its major axis directed in the front-rear direction (longitudinal direction). Further, as shown in FIG. 7, the head side wall 722 gradually increases in diameter from the outer peripheral edge of the magnetic force generation surface 720 upward. The magnetic force generation surface 720 and the head side wall 722 are connected by a gently curved surface.

  As shown in FIG. 7, a substantially cylindrical permanent magnet 723 is built in the bulging portion 721 of the suction head portion 72. The permanent magnet 723 is disposed inside the bulging portion 721 such that one magnetic pole surface and the inner wall surface of the magnetic force generation surface 720 are in contact with each other. The other magnetic pole surface of the permanent magnet 723 is covered with a yoke material 724 made of a soft magnetic material. Thereby, the beauty tool 7 is configured such that the magnetic force generated from the permanent magnet 723 acts more strongly downward.

  In addition, the permanent magnet 723 of this example is a neodymium magnet magnetized in the axial direction. By using the neodymium magnet, the magnetic flux density measured at a point 20 mm downward from the center of the magnetic force generation surface 720 was 43 mT.

As shown in FIG. 6, the working electrode 54 is disposed so that the electrode surface faces the magnetic force generation surface 720 (downward). The working electrode 54 and the counter electrode 55 are formed so that the width in the lateral direction is narrower than the maximum width of the main body 71.

  As shown in FIG. 7, a power supply unit 733, a control unit 73, an LED indicator 713, and a vibration motor 714 are disposed inside the main body unit 71. The power supply unit 733 is arranged between the center in the longitudinal direction and the working electrode 54 inside the main body 71, and is configured to be able to accommodate the battery 733 a in the space inside the main body 71. 6 and 7, the battery 733a is held in the main body 71 by attaching a lid 733b that can be attached to and detached from the main body 71. As shown in FIG.

  The control unit 73 is disposed on the suction head unit 72 side from the longitudinal center of the main body unit 71. Further, the LED indicator 713 is disposed at a substantially central portion in the longitudinal direction in the main body 71 as shown in FIGS. 5 and 7. The LED indicator 713 is configured to emit light upward when an ion introduction current flows from the working electrode 54 to the skin 4. The vibration motor 714 is disposed at the end of the main body 71 on the working electrode 54 side. The vibration motor 714 is driven when an ion introduction current flows from the working electrode 54 to the skin 4 so as to generate vibration.

  Next, the electrical connection between each part in the beauty tool 7 will be described with reference to FIG. The power supply unit 733 is connected to each of the control microcomputer 730 and the voltage application unit 731, the LED indicator 713, and the vibration motor 714 in the control unit 73, and supplies operating power to these units. ing.

  The control unit 73 includes a control microcomputer 730, a voltage application unit 731, and a reflux unit 732. The control unit 73 is connected to the power supply unit 733, the working electrode 54, the counter electrode 55, the LED indicator 713, and the vibration motor 714, and is configured to be able to control operations of these units. The control microcomputer 730 has a function of inputting and outputting a signal for controlling the operation of each unit. The voltage application unit 731 has a function of applying a voltage between the working electrode 54 and the counter electrode 55. The reflux unit 732 has a function of taking a current flowing through the human body from the working electrode 54 or the counter electrode 55 and returning it to the power supply unit 733.

  The control microcomputer 730 and the voltage application unit 731 are connected to each other so that a voltage control signal and a current value selection signal described later can be transmitted. The reflux unit 732 is disposed between the voltage application unit 731 and the ground unit 731 c connected to the negative pole of the power supply unit 733. The reflux unit 732 is connected to an ADC (Analog to Digital Converter) 730a described later of the control microcomputer 730. Thereby, the control unit 73 is configured to be able to input the potential difference in the reflux unit 732 to the control microcomputer 730.

  The control microcomputer 730 includes an ADC 730a, a calculation unit 730b, a signal output unit 730c, and a delay timer 730d. The ADC 730 a has a function of digitizing the potential difference in the reflux unit 732. The calculation unit 730b has a function of determining whether the working electrode 54 and the counter electrode 55 are in contact with the human body. The signal output unit 730c has a function of controlling the current that flows from the working electrode 54 to the skin surface 41 where a cosmetic effect is desired.

  The ADC 730 a is connected to the reflux unit 732 of the control unit 73 and is configured to digitize the potential difference of the reflux unit 732 with respect to the potential of the ground unit 731 c (hereinafter, the potential of the ground unit 731 c is referred to as “ground potential”). Yes. The value of the potential difference digitized by the ADC 730 a is transmitted to the arithmetic unit 730 b in the control microcomputer 730.

  The calculation unit 730b compares the value of the potential difference input from the ADC 730a with a predetermined threshold value. The calculation unit 730b determines that at least one of the working electrode 54 and the counter electrode 55 is not in contact with the human body when the value of the potential difference is less than the predetermined threshold value, and the value of the potential difference is the predetermined value. It is configured to determine that both the working electrode 54 and the counter electrode 55 are in contact with the human body when it is equal to or greater than the threshold value. In addition, the calculation unit 730b is configured to be able to control a signal output from the signal output unit 730c based on both the determination result and the preset operation flow illustrated in FIGS. 9 and 10. Details of the operation flow will be described later.

  The signal output unit 730c is configured to receive a control signal from the calculation unit 730b and output a voltage control signal and a current value selection signal to the voltage application unit 731. The voltage control signal is input to a polarity inversion circuit 731a (to be described later) in the voltage application unit 731 and controls on / off and polarity of a voltage applied between the working electrode 54 and the counter electrode 55. The current value selection signal is input to a constant current circuit 731b described later in the voltage application unit 731 and controls a current value flowing between the working electrode 54 and the counter electrode 55.

  The signal output unit 730c is also connected to the LED indicator 713 and the vibration motor 714, respectively. The signal output unit 730c drives each of the LED indicator 713 and the vibration motor 714 when it is determined that both the working electrode 54 and the counter electrode 55 are in contact with the human body as a result of the determination in the calculation unit 730b. The drive signal to be output is configured to be output.

  The delay timer 730d is activated by the calculation unit 730b when it is determined that at least one of the working electrode 54 and the counter electrode 55 is not in contact with the human body as a result of the determination in the calculation unit 730b. The delay timer 730d has a function of stopping the operation of the calculation unit 730b for a predetermined time. Thereby, in the beauty tool 7, the operation of each unit is stopped along with the operation stop of the calculation unit 730 b until the predetermined time elapses after the delay timer 730 d is activated. The delay timer 730d is configured to restart the operation of the calculation unit 730b after the predetermined time has elapsed.

  The voltage application unit 731 includes a polarity inversion circuit 731a and a constant current circuit 731b, and both are connected to each other. The polarity inversion circuit 731a is connected to the signal output unit 730c of the control microcomputer 730. The polarity inversion circuit 731a is connected to each of the working electrode 54 and the counter electrode 55. Accordingly, the polarity inverting circuit 731a is configured to be able to control the potential difference between the working electrode 54 and the counter electrode 55 based on the voltage control signal output from the signal output unit 730c.

  The constant current circuit 731b has a function of keeping a current flowing between the working electrode 54 and the counter electrode 55 at a constant value. The constant current circuit 731b is connected to the signal output unit 730c of the control microcomputer 730. The constant current circuit 731b is configured to be able to set the current flowing between the working electrode 54 and the counter electrode 55 in two stages based on the current value selection signal output from the signal output unit 730c. In this example, the magnitude of the current is set in two stages, that is, an ion introduction level and a skin care level having a current value smaller than the ion introduction level. The ion introduction level is applied during execution of an ion introduction step S8 and a reset pulse step S9 described later, and the skin care level is applied during execution of a skin care step S11.

  The reflux unit 732 includes a resistor 732a connected between the voltage application unit 731 and the ground unit 731c. As a result, the current taken from the voltage application unit 731 side flows in the resistor 732a toward the grounding unit 731c, and is returned to the negative pole of the power supply unit 733 via the grounding unit 731c. In addition, the voltage application unit 731 and the resistor 732 a in the reflux unit 732 are connected to the ADC 730 a of the control microcomputer 730. Thus, the ADC 730a is configured such that a potential difference with respect to the ground potential at a point between the voltage application unit 731 and the resistor 732a is input.

  Next, an operation flow of the beauty tool 7 shown in FIGS. 9 and 10 will be described. When power is supplied from the power supply unit 733, the beauty device 7 performs step S1 of initializing the control microcomputer 730. At this time, the control microcomputer 730 outputs a current value selection signal to the constant current circuit 731b, and sets the current value to the ion introduction level.

  Thereafter, the control microcomputer 730 performs step S2 of waiting for the elapse of the predetermined time by the delay timer 730d. Note that the delay timer 730d of this example can appropriately set the predetermined time in the range of 50 to 1000 milliseconds.

  Following step S2, the control microcomputer 730 performs step S3 of supplying operating power from the power source unit 733 to the voltage application unit 731 and outputs a voltage control signal from the signal output unit 730c. Thereby, the control microcomputer 730 applies a pulse voltage once between both electrodes while controlling the potential difference between both electrodes so that the working electrode 54 is at a low potential with respect to the counter electrode 55. In this manner, step S4 in which the pulse voltage is applied once between the working electrode 54 and the counter electrode 55 is performed. In this example, the value of the pulse voltage in step S4 is 5V.

  Subsequently, as shown in FIG. 9, step S <b> 5 for measuring a potential difference in the reflux unit 732 is performed. In step S5, when both the working electrode 54 and the counter electrode 55 are in contact with the skin 4, a pulse current based on the pulse voltage flows from the counter electrode 55 to the working electrode 54 through the human body. The pulse current is taken into the control unit 73 from the working electrode 54, and a potential difference is generated between both ends of the resistor 732a in the reflux unit 732 as a waveform F4 illustrated in FIG. Then, the potential difference generated between both ends of the resistor 732a, that is, the potential difference in the reflux unit 732 with reference to the ground potential is input to the ADC 730a of the control microcomputer 730, and the value is measured.

  On the other hand, when at least one of the working electrode 54 and the counter electrode 55 is not in contact with the skin 4, no current flows through the resistor 732a even when the pulse voltage is applied, and there is a potential difference between both ends of the resistor 732a. Does not occur. Therefore, when at least one of the working electrode 54 or the counter electrode 55 is not in contact with the skin 4, the value of the potential difference is 0V.

  Thereafter, the control microcomputer 730 determines, in the calculation unit 730b, the contact state between the working electrode 54 and the counter electrode 55 and the human body based on the comparison result between the potential difference and the predetermined threshold value L (see FIG. 11). I do. If the potential difference measured in step S5 is less than the threshold value L, the control microcomputer 730 determines that at least one of the working electrode 54 and the counter electrode 55 is not in contact with the human body (step S6, “No”). . In this case, the control microcomputer 730 returns to step S2 and starts the delay timer 730d. The control microcomputer 730 repeats Steps S2 to S6 while it is determined in Step S6 that at least one of the working electrode 54 and the counter electrode 55 is not in contact with the human body. In this example, the threshold value L can be appropriately set between 50 and 200 mV.

  On the other hand, as shown in FIG. 11, when the potential difference in the reflux unit 732 with reference to the ground potential is greater than or equal to the threshold L in step S6, the control microcomputer 730 indicates that both the working electrode 54 and the counter electrode 55 are It determines with contacting (step S6, "Yes"). In this case, as shown in FIG. 9, the control microcomputer 730 outputs a current value selection signal to the constant current circuit 731b, and performs step S7 of setting the current value to the ion introduction level. After step S7, the control microcomputer 730 sends a voltage control signal to the voltage application unit 731 so that an ion introduction current flows from the working electrode 54 to the skin 4.

  As shown in FIG. 9, the ion introduction current includes an ion introduction step S8 in which a current of one polarity (FIG. 12, F1) is passed to the contact portion between the working electrode 54 and the skin 4, and a pulse current of the other polarity to the contact portion. A reset pulse step S9 for flowing (FIG. 12, F2) and a skin care step S11 for flowing a current (FIG. 12, F3) whose polarity is alternately switched to the contact portion are sequentially repeated. Thereby, the waveform of the iontophoretic current flowing through the skin 4 is such that the basic waveforms F1 to F3 shown in FIG. 12 are repeated.

  Further, the control microcomputer 730 outputs a drive signal from the signal output unit 730c to the LED indicator 713 and the vibration motor 714 while the ion introduction current flows through the skin 4 (FIG. 10, step T1). As a result, the LED indicator 713 and the vibration motor 714 are driven while both the working electrode 54 and the counter electrode 55 are in contact with the human body.

  More specifically, in the ion introduction step S8, the control microcomputer 730 controls the potential difference between the two electrodes so that the working electrode 54 is at a low potential with respect to the counter electrode 55, and applies a pulse voltage between the two electrodes. Apply multiple times. As a result, the working electrode 54 can cause the negative pulse current to flow through the skin 4 a plurality of times as in the basic waveform F1 shown in FIG.

  In the reset pulse step S9, the control microcomputer 730 applies a pulse voltage once between both electrodes while controlling the potential difference between both electrodes so that the working electrode 54 is at a high potential with respect to the counter electrode 55. Thereby, the working electrode 54 can flow a positive pulse current to the skin 4 as in the basic waveform F2 shown in FIG.

  Further, after the reset pulse step S9, as shown in FIG. 9, the control microcomputer 730 outputs a current value selection signal to the constant current circuit 731b, and performs step S10 for setting the current value to the skin care level.

  As shown in FIG. 9, the control microcomputer 730 performs the skin care step S11 after performing step S10. In skin care step S <b> 11, the control microcomputer 730 applies a rectangular wave between the electrodes, in which the level of the potential difference of the working electrode 54 with respect to the counter electrode 55 is alternately switched. As a result, the working electrode 54 can cause the skin 4 to pass a rectangular wave current in which the positive polarity and the negative polarity are alternately switched as in the basic waveform F3 shown in FIG.

  Further, as shown in FIG. 10, the control microcomputer 730 uses the pulse of the ion introduction current flowing through the skin 4 in parallel with steps S7 to S11, so that the working electrode 54 and the counter electrode 55 are in contact with the human body. It has a skin detection function to make the determination. That is, the control microcomputer 730 uses the pulses that flow to the skin 4 in the ion introduction step S8, the reset pulse step S9, and the skin care step S11 to return to the ground potential generated due to the pulse current as in step S5. The unit 732 is configured to perform the potential difference measurement T2.

  Then, as shown in FIG. 10, the control microcomputer 730 performs Step T <b> 3 for determining the contact state between the working electrode 54 and the counter electrode 55 and the human body based on the result of the potential difference measurement of the reflux unit 732 described above. The determination of the contact state between the working electrode 54 and the counter electrode 55 and the human body in step T3 may be performed based on the result of potential difference measurement for one pulse current, or the results of potential difference measurement for a plurality of pulse currents are combined. You may go. Moreover, the pulse current used for determination of the contact state mentioned above can be suitably selected from the pulse current in each step of the ion introduction step S8, the reset pulse step S9, and the skin care step S11.

  For example, in this example, the determination of the contact state in step T3 is whether the potential difference between both ends of the resistor 732a due to the pulse current in the reset pulse step S9 (FIG. 12, F2) is continuously lower than the threshold value L a predetermined number of times. Implemented on the basis of no. That is, the control microcomputer 730 of the present example causes the working electrode 54 when the potential difference caused by the pulse current (FIG. 12, F2) is continuously less than the threshold value L for a predetermined number of times (step T3, “Yes”). Alternatively, it is determined that at least one of the counter electrodes 55 is not in contact with the human body. In this case, the control microcomputer 730 stops generating the ion introduction current and stops outputting the drive signal to the LED indicator 713 and the vibration motor 714 (step T4).
