[0001] The present invention relates to a core material for an eyebrow pencil and a method for manufacturing the core material for an eyebrow pencil.

Background Art

[0002] The key to making the eyebrows drawn with an eyebrow pencil look like natural eyebrows is a fluffy feeling. Therefore, the core material for an eyebrow pencil is required to have the performance of being able to draw eyebrows while leaving the texture as a powder of eyebrow ink. At the same time, the method of drawing eyebrows also becomes a drawing method using short strokes like the hair drawing in Japanese painting, conscious of the naturally growing eyebrows. However, drawing eyebrows with existing eyebrow pencils is a visual symptomatic treatment for thin eyebrows and is not a radical treatment. A common radical treatment for thin eyebrows is the application of a hair growth agent. Furthermore, the position where the eyebrow ink is applied in symptomatic treatment and the position where eyebrows are desired to grow in radical treatment completely coincide, and the amount of eyebrow ink applied and the amount of hair growth agent to be applied show a positive correlation. Therefore, it is obvious that applying eyebrow ink and a hair growth agent simultaneously is optimal both therapeutically and in terms of time performance. A technique for kneading eyebrow ink and a hair growth agent to form a core material for an eyebrow pencil has been provided (see Patent Document 1). This technique simply mixes a hair growth agent having a hair growth and hair nourishing effect with the base material of the core material for an eyebrow pencil.

[0005] The present invention has been made in view of the above circumstances, and aims to provide an eyebrow pencil lead material and a method for manufacturing an eyebrow pencil lead material that allows for precise application of a hair growth serum to the area where eyebrows are to be grown, while giving the drawn eyebrows a fluffy appearance. [Means for solving the problem]

[0006] To apply eyebrow growth serum precisely to the areas where you want to grow eyebrows, while giving the drawn eyebrows a soft, fluffy look, it is necessary to apply the powder-type eyebrow pencil and the fluid, non-solid (liquid, gel, etc.) eyebrow growth serum in short strokes, ensuring they are applied with minimal mixing between each stroke.

[0007] Therefore, the eyebrow pencil lead material according to the present invention comprises a base material and a number of microcapsules containing hair growth agents, Equipped with, The material is characterized in that a large number of microcapsules containing the hair growth agent are uniformly dispersed in the substrate.

[0008] While oil-based substrates are generally used as the aforementioned base material, they are not limited to oil-based substrates; aqueous substrates such as glycerin may also be used. Furthermore, when using an oil-based base material, a coloring agent (e.g., a pigment) may be kneaded into the oil-based base material, and a solid agent may be heated, melted, and kneaded. That is, the oil-based base material and a solid agent that creates a card-house structure that produces a crumbly texture may be heated and melted simultaneously, a coloring agent pigment may be added and kneaded, and then microcapsules containing a hair growth agent, which have a melting temperature higher than the melting temperature of the base material, may be kneaded in. Adding a solidifying agent to an oil-based base eliminates the stickiness of the oil-based base, creating a crumbly (fragile) texture and a powdery feel. To make eyebrows look natural, a soft, fluffy look is necessary, and this fluffy look is achieved through a powdery texture. In other words, the reason why eyebrow pencil lead materials are designed to crumble easily is to make the drawn eyebrows look natural and to give them a soft, fluffy appearance.

[0009] In the eyebrow pencil lead material according to the present invention, when drawing eyebrows, the movement of the eyebrow pencil (eyebrow pencil lead material) to draw diagonal hatching lines with short strokes without the lines crossing is almost parallel and unidirectional, which is the opposite of the rotational and reciprocating movements of a brush used when mixing multiple paints on a palette for painting, etc. In this case, the eyebrow pencil lead material according to the present invention comprises a base material and numerous microcapsules containing a hair growth agent, such as a fluid liquid, which are encapsulated inside. Since the numerous microcapsules containing the hair growth agent are uniformly dispersed in the base material, when the eyebrow pencil lead material moves in one direction in parallel lines where the lines do not intersect, the process of the base material crumbling and coloring, and the process of the hair growth agent-containing microcapsules exposed in the coloring process being pushed by the base material behind them, being destroyed by friction with the skin or slight pressure, and releasing the hair growth agent inside, are automatically repeated alternately. This prevents overwriting with different components in a single stroke and enables continuous alternating application without mixing components of different purposes.

[0010] Even if the drawn lines are precisely overwritten by intersections or other means, the amount of hair growth agent contained in the microcapsules is so minute that, due to absorption into the skin and drying, the liquid (hair growth agent) inside the microcapsules loses its ability to emulsify the powdered base material before it can impregnate the powdered base material. Therefore, the powdery feel of the drawn eyebrows is not lost. Therefore, according to the present invention, it is possible to apply a hair growth serum precisely to the area where you want to grow eyebrows, while giving the drawn eyebrows a fluffy appearance.

[0011] Furthermore, the method for manufacturing the eyebrow pencil lead material according to the present invention is characterized by solidifying the base material by kneading the molten base material uniformly with a large number of hair growth agent-containing microcapsules without melting them, and without rupturing the hair growth agent-containing microcapsules, and then cooling the mixture.

[0012] In the method for manufacturing eyebrow pencil lead material according to the present invention, in order to allow the base material of the eyebrow pencil lead material, which is used in a solid state, and the hair growth agent, which is used in a liquid state, to coexist in a homogeneous state when used, the properties of liquids that allow impurities to be homogeneously dispersed by stirring, etc., are utilized. The base material of the eyebrow pencil lead material, which is used in a solid state, is heated and melted into a liquid state, and hair growth agent-containing microcapsules containing the liquid hair growth agent are kneaded together. Once a homogeneous distribution is achieved, only one of the liquids, i.e., the base material, is solidified, and the eyebrow pencil lead material can be easily formed with the hair growth agent in the microcapsules remaining in liquid and homogeneously distributed within the solid lead material (base material).

[0013] Furthermore, another method for manufacturing an eyebrow pencil lead material according to the present invention is characterized by sequentially stacking the molten base material and the hair growth agent-containing microcapsules alternately in a casting mold a predetermined number of times, and then solidifying the base material by cooling.

[0014] In the method for manufacturing eyebrow pencil lead material according to the present invention, a granular solid base material and microcapsules containing a liquid hair growth agent are alternately placed in a casting mold and layered. The mixture is then heated to a temperature at which only the base material melts, and cooled while mixed. This allows for the easy formation of eyebrow pencil lead material in which the hair growth agent contained in the microcapsules remains in liquid form and is uniformly distributed within the solid base material.

[0015] Furthermore, yet another method for manufacturing an eyebrow pencil lead material according to the present invention is characterized by sequentially stacking the base material in solid powder form and the hair growth agent-containing microcapsules alternately in a mold for a predetermined number of times, melting the base material at a temperature at which only the powder base material melts, and then cooling it to re-solidify the melted base material.

[0016] In the method for manufacturing eyebrow pencil lead material according to the present invention, a solid powder base material and microcapsules containing liquid hair growth agent are sequentially stacked a predetermined number of times in a mold, and the base material is thermally melted at a temperature at which only the powder base material melts, and then cooled to re-solidify the molten base material. This allows for the easy formation of eyebrow pencil lead material in which the hair growth agent contained in the microcapsules remains liquid and is uniformly distributed within the solid base material. [Effects of the Invention]

Embodiments for Carrying Out the Invention

[0019] Hereinafter, embodiments of a core material for an eyebrow pencil and a method for manufacturing the core material for an eyebrow pencil according to the present invention will be described with reference to the drawings. [[ID=二十一]] As shown in FIG. 1, the core material 10 for an eyebrow pencil of the present embodiment includes a base material 11 and a large number of microcapsules 12 containing a hair growth agent. Further, the core material 10 for an eyebrow pencil is inserted and fixed into the shaft portion 13 to form an eyebrow pencil. The tip of the core material 10 for an eyebrow pencil protrudes from the tip of the shaft portion 13. When the tip of the core material 10 for an eyebrow pencil is worn by use, the tip of the core material 10 for an eyebrow pencil is drawn out from the tip of the shaft portion 13 or the tip of the shaft portion 13 is cut to protrude the tip of the core material 10 for an eyebrow pencil from the tip of the shaft portion 13 by a predetermined length. In addition, a large number of microcapsules 12 containing a hair growth agent are uniformly dispersed in the base material 11.

[0020] The base material 11 is not particularly limited as long as it can be a base material of the core material 10 for an eyebrow pencil. For example, an oily base material such as stearic acid having a melting point of 67 to 72 ° C, beeswax having a melting point of 49 to 56 ° C, and hydrogenated castor oil having a melting point of 78 to 90 ° C is used. Further, a coloring agent is mixed in the base material 11, and the base material 十一 exhibits a predetermined color (for example, black, etc.) by the coloring agent. Furthermore, the base material 11 is mixed with solidifying agents (not shown) such as ozokelite, which has a melting point of 61-90°C, and ceresin, which has a melting point of 53-79°C. Adding solidifying agents eliminates the stickiness of the oily base material 11, creating a crumbly texture and a powdery feel. To make eyebrows look natural, a soft, fluffy texture is necessary, and this fluffy texture is created by the powdery feel. In other words, the purpose of making the eyebrow pencil lead material crumbly is to make the drawn eyebrows look natural and to give them a fluffy texture.

[0021] When using an eyebrow pencil with this configuration, the user grasps the shaft portion 13 and draws eyebrows with the tip of the eyebrow pencil lead material 10, coloring the eyebrows with the coloring agent. When drawing eyebrows, the eyebrow pencil lead material 10 is moved in one direction parallel to the eyebrows so that the lines do not intersect. This causes the base material 11 to break down and color the eyebrows (coloring step), and the hair growth agent-containing microcapsules 12 exposed in the coloring step are pushed by the base material 11 behind the hair growth agent-containing microcapsules 12, and are destroyed by friction with the skin and slight pressure, releasing the hair growth agent inside and applying it to the epidermis (application step). When drawing eyebrows, the coloring and application processes are automatically repeated alternately, preventing the overwriting of different components with a single brushstroke and allowing for continuous, alternating application without mixing different components.

[0022] The hair growth agent-containing microcapsules 12 consist of a liquid (or gel-like) hair growth agent encapsulated in microcapsules, and their size (diameter) ranges from a few micrometers to several thousand micrometers. Microcapsules are formulated using materials that do not undergo thermal melting or dissolution even when the base material 11 is in a molten state, and that do not cause any health problems to the human body. These materials include carrageenan with a melting temperature of 70°C, gellan gum with a melting temperature of 85-90°C, and agarose (agar) with a melting temperature of 90°C. Hair growth tonics may use, for example, liquid bimatoprost, but are not limited to this. Other ingredients may include Swertia japonica extract, Panax ginseng root extract, panthenyl ethyl ester, hinokitiol, rosemary extract, Scots pine cone extract, watercress extract, Lamium album extract, etc., and a combination of several of these may be used. Hair growth tonics should be used in liquid or gel form at room temperature.

[0023] When a hair growth agent having such liquid or gel-like fluidity is enclosed in a capsule, a hair growth agent-containing microcapsule 12 is formed. Then, the eyebrow pencil lead material 10 is manufactured by kneading a large number of microcapsules containing hair growth agent 12 into the molten base material 11, uniformly without melting them, and without rupturing the microcapsules containing hair growth agent 12, and then cooling the mixture to solidify the base material 11.

[0024] When mixing the base material 11 with a large number of microcapsules 12 containing hair growth agent, the mixing is carried out using a mixing device 20, for example, as shown in Figure 2. The mixing device 20 comprises an outer container 21, an inner container 22 installed inside the outer container 21 at predetermined intervals, and a stirring blade 27. A heating medium 23 is filled between the outer container 21 and the inner container 22, and this heating medium 23 is heated by a heater 24.

[0025] Furthermore, a piston section 25 and an insertion tube 26 for introducing hair growth agent-containing microcapsules 12 are provided above the inner container 22, and the insertion tube 26 is supported by the piston section 25. The stirring blade 27 is attached to the piston section 25 so as to be able to move up and down. In other words, the stirring blade 27 is attached to the piston section 25 so as to be able to reciprocate up and down between an upper position where the stirring blade 27 is located above the inner container 22 and a lower position where it is located inside the inner container 22. Furthermore, the inside of the input tube 26 is filled with numerous microcapsules 12 containing hair growth agents, and the lower end opening of the input tube 26 can be opened and closed by an opening / closing member 26a. Furthermore, a through hole 22a is formed in the bottom of the inner container 22, and this through hole 22a opens into the bottom of the outer container 21. The through hole 22a can also be opened and closed by a sliding opening / closing member 28 that is slidable in the horizontal direction.

[0026] When mixing the base material 11, coloring agent 15, and numerous microcapsules 12 containing hair growth agent using such a mixing device 20, first, as shown in Figure 2(a), the base material 11, coloring agent 15, and solid agent (not shown) are placed inside the inner container 22, and then the inner container 22 is heated by heating the heating medium 23 with a heater 24. As a result, as shown in Figure 2(b), the base material 11 and solid agent melt, while the coloring agent 15 does not melt, and these are mixed together. Next, the opening / closing member 26a of the input cylinder 26 is opened, and the microcapsules 12 containing hair growth agent are placed into the inner container 22 from above. In this state, the base material 11 and solid agent have melted, but the coloring agent has not. Furthermore, the microcapsules 12 containing coloring agent and hair growth agent have not melted or dissolved; in other words, the microcapsules 12 containing hair growth agent have not ruptured due to heat, and the liquid (or gel-like) hair growth agent is retained inside.

[0027] Next, as shown in Figure 2(c), the opening / closing member 26a of the input cylinder 26 is closed, and the piston section 25 is kept stationary or slightly lowered, while the stirring blade 27 is lowered so as to move away from the piston section 25. This inserts the stirring blade 27 into the mixture of the molten base material 11 and solid agent in the inner container 22 and the coloring agent that has not been molten, and the stirring blade 27 is rotated. As a result, the mixture of the base material 11, coloring agent 15 and solid agent is kneaded, and the mixture is kneaded with the numerous hair growth agent-containing microcapsules 12, resulting in a mixture in which the numerous hair growth agent-containing microcapsules 12 are uniformly dispersed, and a kneaded product is obtained in which the base material 11, coloring agent 15, solid agent and hair growth agent-containing microcapsules 12 are uniformly kneaded.

[0028] In this case, to prevent the hair growth agent-containing microcapsules 12 from being crushed by the pressure during mixing, the bursting pressure of the hair growth agent-containing microcapsules 12 to be used is measured in advance using a microcompression testing machine (manufactured by Shimadzu Corporation, which performs compression tests on microcapsules containing fragrance components), and the mixing is carried out while controlling the viscosity of the base material by heating, etc., and adjusting the stirring torque with a torque measuring device (for example, a torque measuring device manufactured by Sansho Co., Ltd.) so as not to exceed the bursting pressure of the hair growth agent-containing microcapsules 12 measured in advance, thereby preventing the hair growth agent-containing microcapsules 12 from being crushed by shear stress, etc.

[0029] Next, as shown in Figure 2(d), the sliding opening / closing member 28 is slid horizontally to open the through hole 22a and lower the piston portion 25 to a predetermined position inside the inner container 22. At this time, the stirring blade 27 is stopped inside the inner container 22. As the piston portion 25 descends, the kneaded material in the inner container 22 is pushed out through the through hole 22a to become the eyebrow pencil lead material 10. When pushing the kneaded material out of the inner container 22, it is pushed out at regular intervals so that the pushed-out eyebrow pencil lead material 10 reaches a predetermined length.

[0030] As shown in Figure 3, the eyebrow pencil lead material 10, pushed out from the inner container 22 by the piston 25, is successively poured into a cooling tank 30 located below the inner container 22. The cooling tank 30 is filled with cooling water, and the eyebrow pencil lead material 10 poured into the cooling tank 30 solidifies as it is cooled by the cooling water. A drain hole 30a is formed at the bottom of the cooling tank 30, and this drain hole 30a is opened and closed by a horizontally movable sliding opening / closing member 31. Subsequently, by sliding the sliding opening / closing member 31 to open the drain hole 30a, the cooling water is discharged from the cooling tank 30 to the outside, and a predetermined number of eyebrow pencil lead materials 10 are accumulated in the cooling tank 30.

[0031] Furthermore, as shown in Figure 4, a predetermined shape and size of eyebrow pencil lead material 10A may be obtained by extruding the kneaded material 17 from the inner container 22. This eyebrow pencil lead material 10A can have a different shape and size from the eyebrow pencil lead material 10 shown in Figure 3. Below the inner container 22, a silicone mold 33 is provided so as to be movable in the horizontal direction, and multiple mold holes 33a are formed in the silicone mold 33 at predetermined intervals along the direction of movement of the silicone mold 33. The kneaded material 17, extruded from the inner container 22 by the piston 25, is filled into the mold holes 33a of the silicone mold 33. After a predetermined amount of kneaded material 17 is filled into the first mold hole 33a, the silicone mold 33 is moved horizontally by a predetermined distance, thereby filling the next mold hole 33a with kneaded material 17. By repeating this process a predetermined number of times, all the mold holes 33a are filled with kneaded material 17.

[0032] Next, the silicone mold 33, with all its mold holes 33a filled with the kneaded material 17, is immersed in a cooling tank 34 located below the silicone mold 33, with its upper end protruding above the water surface. The entire silicone mold 33 is cooled by the cooling water in the cooling tank 34, thereby cooling the kneaded material 17 in the mold holes 33a. This process yields the eyebrow pencil lead material 10A. As shown in Figure 5, the silicone mold 33 can be opened and closed using one edge along its longitudinal direction as an axis. With the silicone mold 33 closed, the kneaded material 17 is filled into the silicone mold 33 as described above, and then cooled in the cooling tank 34. After that, the silicone mold 33 is removed from the cooling tank 34, and the silicone mold 33 is opened using one edge as an axis to remove the eyebrow pencil lead material 10A, which is the cooled kneaded material 17, from the silicone mold 33.

[0033] If the mixing process using the aforementioned torque measuring device is inconvenient due to the time required for homogenization and the risk of breakage of the hair growth agent-containing microcapsules 12, then, as an alternative method for manufacturing the eyebrow pencil lead material 10, the eyebrow pencil lead material 10 may be obtained by alternately layering the molten base material 11 and the hair growth agent-containing microcapsules 12 in a mold for casting the lead material a predetermined number of times, and then cooling to solidify the base material.

[0034] In other words, the rotary lamination apparatus 40 used in the manufacturing method of the eyebrow pencil lead material of this embodiment, as shown in Figure 6, comprises a substrate input section 41 for inputting the substrate 11, a capsule input section 42 for inputting the hair growth agent-containing microcapsules 12, and a lamination cylinder 43 for laminating the input substrate 11 and the hair growth agent-containing microcapsules 12.

[0035] There are three substrate input sections 41 and three capsule input sections 42, for a total of six, which are arranged alternately at predetermined intervals along the circumferential direction. As shown in Figure 7, the substrate input section 41 is formed in a double-tube shape and includes a cylindrical substrate input hole 41a located in the center and a heating section 41b located outside the substrate input hole 41a. Figure 7 shows the substrate input section 41, capsule input section 42, and stacking cylinder 43 arranged alternately along the circumferential direction in a linear configuration. The substrate 11 is filled into the substrate input hole 41a from above, and the bottom of the substrate input hole 41a can be opened and closed by an opening / closing member 44. The heating section 41b is filled with a heating medium 46, which is heated by a heater 47. The capsule insertion section 42 is formed in a cylindrical shape, into which microcapsules 12 containing hair growth agent are filled from above, and the bottom can be opened and closed by an opening / closing member 48.

[0036] The lamination cylinder 43 is formed in a thick cylindrical shape from flexible silicon, and as shown in Figure 6, it consists of an outer cylindrical portion 43a and an inner cylindrical portion 43b arranged coaxially inside the outer cylindrical portion 43a, with the inner circumferential surface of the outer cylindrical portion 43a and the outer circumferential surface of the inner cylindrical portion 43b in close contact. The outer cylindrical portion 43a is formed by bending a strip-shaped silicon plate into a cylindrical shape, with a fitting projection 45a formed at one end of the silicon plate and a fitting recess 45b formed at the other end. The outer cylindrical portion 43a is formed in a cylindrical shape by bending the silicon plate into a cylindrical shape and fitting the opposing fitting projection 45a and fitting recess 45b together. Furthermore, the inner cylindrical portion 43b is formed in the same way as the outer cylindrical portion 43a by bending a strip-shaped silicon plate into a cylindrical shape. A fitting projection is formed at one end of the silicon plate, and a fitting recess is formed at the other end. The inner cylindrical portion 43b is formed into a cylindrical shape by bending the silicon plate into a cylindrical shape and fitting the opposing fitting projection and fitting recess together. Since the outer surface of the inner cylindrical portion 43b is constrained by the outer cylindrical portion 43a, the cylindrical shape is maintained even if the silicon plate forming the inner cylindrical portion 43b does not have fitting projections and fitting recesses formed on it.

[0037] Furthermore, mold holes 45 are formed at predetermined intervals in the circumferential direction at the contact portion (boundary) between the outer cylindrical portion 43a and the inner cylindrical portion 43b. That is, half-cut holes for forming mold holes 45 are formed on the inner circumferential surface of the outer cylindrical portion 43a and the outer circumferential surface of the inner cylindrical portion 43b, respectively. By positioning the inner cylindrical portion 43b inside the outer cylindrical portion 43a and aligning the respective half-cut holes radially, the mold holes 45 are formed. Furthermore, each mold hole 45 is positioned directly below the substrate input section 41 and the capsule input section 42. The lamination cylinder 43, which consists of an outer cylindrical section 43a and an inner cylindrical section 43b, is provided to be rotatable around its axis by a rotation mechanism (not shown). By rotating this lamination cylinder 43 by a predetermined angle, each mold hole 45 is positioned directly below the substrate input section 41 and the capsule input section 42. In other words, by rotating the lamination cylinder 43 by a predetermined angle, each mold hole 45 moves circumferentially and is positioned directly below the substrate input section 41 and the capsule input section 42, which are located forward in the direction of rotation. Furthermore, a cooling tank 50 is installed directly below the stacking cylinder 43, and the stacking cylinder 43 is cooled when it is inserted into this cooling tank 50.

[0038] To alternately stack the thermally melted substrate 11 and the hair growth agent-containing microcapsules 12 using the rotary lamination apparatus 40 configured in this manner, the following procedure is followed. Specifically, as shown in Figure 7, first, a predetermined amount of base material 11, coloring agent (not shown), and solidifying agent (not shown) is put into the base material input hole 41a of the first base material input section 42 (the leftmost base material input section 42 in Figure 7). The put-in base material 11 and solidifying agent are melted by the heating section 41b, but the coloring agent is not melted. Next, a predetermined amount of the melted base material 11 and solidifying agent, and the non-melted coloring agent are put into the first mold hole 45 (the leftmost mold hole 45 in Figure 7) from the base material input hole 41a of the base material input section 41 located directly above it. In this case, the bottom of the base material input hole 41a is opened by an opening / closing member 44 provided at the bottom of the base material input hole 41a. As a result, the bottom layer of base material 11 is filled into the bottom of the mold hole 45. This base material 11 contains a mixture of the melted solidifying agent and the non-melted coloring agent.

[0039] Next, the bottom of the open substrate insertion hole 41a is closed by the opening / closing member 44, and then the lamination cylinder 43 is rotated by a predetermined angle by one pitch to position the first mold hole 45 directly below the capsule insertion section 42, after which a predetermined amount of hair growth agent-containing microcapsules 12 are inserted from the capsule insertion section 42. In this case, the bottom of the capsule insertion section 42 is opened by the opening / closing member 48 provided at the bottom of the capsule insertion section 42. As a result, the hair growth agent-containing microcapsules 12 are laminated on the bottommost substrate 1. These hair growth agent-containing microcapsules 12 are neither melted nor dissolved by heat. Next, the bottom of the open capsule insertion section 42 is closed by the opening / closing member 48, and then the stacking cylinder 43 is rotated by a predetermined angle by another pitch to position the mold hole 45 directly below the next substrate insertion section 41. Then, a predetermined amount of the molten substrate 11 and solid agent, and the non-molten coloring agent are poured into the mold hole 45 through the substrate insertion hole 41a by opening the opening / closing member 44. As a result, the next substrate 1 is stacked on top of the stacked hair growth agent-containing microcapsules 12. This substrate 11 contains a mixture of the molten solid agent and the non-molten coloring agent.

[0040] In this process, the lamination cylinder 43 is rotated by a predetermined angle by one pitch, and the substrate 11, colorant, and solid agent are introduced into the mold hole 45 from the substrate introduction section 41, and the hair growth agent-containing microcapsules 12 are introduced into the mold hole 45 from the capsule introduction section 42, and these processes are repeated sequentially a predetermined number of times, thereby alternately laminating the substrate 11 containing the colorant and solid agent and the hair growth agent-containing microcapsules 12 in the mold hole 45. In this way, the base material 11 containing the coloring agent and solidifying agent and the microcapsules 12 containing the hair growth agent are sequentially layered in all of the mold holes 45, thereby uniformly dispersing the microcapsules 12 containing the hair growth agent. In other words, a base material 11 containing a coloring agent and a solidifying agent and microcapsules 12 containing hair growth agent are alternately layered to create a pseudo-mixed state, and then sequentially cooled to solidify only the liquid on the base material 11 while suppressing thermal damage to the microcapsules 12 containing hair growth agent. This forms a solid eyebrow pencil core material 10 in which a large number of microcapsules 12 containing liquid hair growth agent are uniformly dispersed within the base material 11. When solidifying the liquid on the base material 11, a layering cylinder 43 filled with base material 11 and microcapsules 12 containing hair growth agent is inserted into a cooling tank 50 (see Figure 6) to solidify the liquid on the base material 11 and obtain the eyebrow pencil core material 10.

[0041] As described above, according to this embodiment, the eyebrow pencil lead material 10 containing a coloring agent and a solidifying agent comprises a base material 11 and numerous microcapsules 12 containing liquid hair growth agent. Since the numerous microcapsules 12 containing hair growth agent are uniformly dispersed in the base material 11, when the eyebrow pencil lead material 10 moves in one direction in parallel lines where the lines do not intersect, the base material 11 collapses and is colored, and the microcapsules 12 containing hair growth agent that are exposed in the coloring process are pushed by the base material 11 behind them, and are destroyed by friction with the skin or slight pressure, releasing the hair growth agent inside, which is then applied. These processes are automatically repeated alternately, preventing the overwriting of different components with a single stroke and enabling continuous alternating application without mixing of components with different purposes.

[0042] Even if the drawn lines are precisely overwritten by intersections or other means, the amount of hair growth agent contained in the microcapsules 12 is extremely small. Therefore, due to absorption into the skin and drying, the liquid (hair growth agent) in the microcapsules 12 loses its ability to emulsify the powdered base material 11 before it can impregnate the powdered base material 11. As a result, the powdery feel of the drawn eyebrows is not lost. Therefore, it is possible to apply the hair growth serum precisely to the areas where you want to grow eyebrows, while giving the drawn eyebrows a soft, fluffy look.

[0043] Furthermore, according to the manufacturing method of the eyebrow pencil lead material 10 of this embodiment, the base material 11 is solidified by kneading a large number of hair growth agent-containing microcapsules 12 into a heat-melted base material 11 containing a coloring agent and a solidifying agent, uniformly without melting the microcapsules 12 and without rupturing them, and then cooling the mixture. As a result, the eyebrow pencil lead material 10 can be easily formed with the hair growth agent in the microcapsules 12 uniformly distributed in liquid form within the solid lead material (base material 11). Furthermore, according to another method for manufacturing the eyebrow pencil lead material 10 according to this embodiment, a heat-melted base material 11 containing a coloring agent and a solidifying agent and microcapsules 12 containing hair growth agents are alternately layered in a casting mold (mold hole 45) a predetermined number of times, and the base material 11 is solidified by cooling. As a result, the eyebrow pencil lead material 10 can be easily formed with the hair growth agent in the microcapsules 12 uniformly distributed in liquid form within the solid lead material (base material 11).

[0044] Furthermore, in the above-described embodiment, the molten substrate and the microcapsules containing the hair growth agent were alternately stacked a predetermined number of times and then cooled. However, in another embodiment, the solid powder substrate and the microcapsules containing the hair growth agent may be alternately stacked a predetermined number of times in the molded pore, the substrate may be molten at a temperature at which only the powder substrate melts, and then cooled to re-solidify the molten substrate.

[0045] In this case, although not shown in the illustration, the rotary lamination apparatus used in this embodiment includes a substrate input section for inputting substrates, a capsule input section for inputting microcapsules containing hair growth agents, a lamination cylinder for laminating the input substrates and microcapsules containing hair growth agents, and a heating section for heating the lamination cylinder. Unlike the substrate input section 41 shown in Figure 7, the substrate input section does not have a heating section 41b and is equipped with a cylindrical substrate input hole. The lamination cylinder, like the lamination cylinder 43 shown in Figure 6, is equipped with multiple mold holes arranged at predetermined intervals in the circumferential direction. Each mold hole moves in the circumferential direction when the lamination cylinder is rotated by a predetermined angle, and is positioned directly below the substrate input section and capsule input section located in the forward direction of rotation.

[0046] In this embodiment, first, a predetermined amount of solid powder base material, colorant, and solidifying agent is placed into the first base material input section. Next, the lamination cylinder is rotated by a predetermined angle of one pitch to position the first mold opening directly below the capsule input section, and then a predetermined amount of hair growth agent-containing microcapsules is placed into the capsule input section. As a result, the hair growth agent-containing microcapsules are laminated on top of the bottom layer of base material. Next, the lamination cylinder is rotated by a predetermined angle by another pitch to position the mold opening directly below the next substrate input section. Then, a predetermined amount of powdered substrate, solidifying agent, and coloring agent is poured into the mold opening from the substrate input section. This results in the next substrate containing the solidifying agent and coloring agent being laminated on top of the already laminated microcapsules containing the hair growth agent.

[0047] In this process, the lamination cylinder is rotated by a predetermined angle by one pitch, and the powder substrate, colorant, and solid agent are introduced into the mold cavity from the substrate introduction section, and the microcapsules containing the hair growth agent are introduced into the mold cavity from the capsule introduction section, and these processes are repeated sequentially a predetermined number of times. This process alternately layers the powder substrate containing the colorant and solid agent and the microcapsules containing the hair growth agent into the mold cavity. Next, after layering a powder substrate containing a coloring agent and a solidifying agent, along with microcapsules containing hair growth stimulants, into all the mold holes, the layering cylinder is heated by a heating unit to melt the powder substrate and solidifying agent, while the substrate is melted at a temperature where the microcapsules containing hair growth stimulants do not melt or dissolve. After this, the molten substrate is re-solidified by cooling. This makes it easy to form an eyebrow pencil core material in which numerous microcapsules containing hair growth stimulants are uniformly dispersed within the substrate containing the coloring agent and solidifying agent.
