[0002] Cosmetics are used for beauty and skin health, and various devices are being proposed for their manufacture. In particular, the market for customized cosmetics that reflect users' skin conditions and needs is growing, and various devices are being proposed to produce such customized cosmetics.

[0003] Generally, cosmetics require emulsification technology, which disperses one of two immiscible fluids, such as water and oil, into small particles and places them in a stable state within the other fluid. This emulsification technology is widely used in the manufacturing of cosmetics such as lotions, creams, essences, massage creams, cleansing creams, makeup bases, foundations, eyeliners, and mascaras.

[0004] Conventional cosmetic manufacturing devices have utilized various mechanisms to emulsify fluids with opposite characteristics in order to form an emulsion. Consequently, cosmetic manufacturing devices have large volumes and complex operating mechanisms, which has made it difficult to manufacture them in a form suitable for general household use.

[0005] In addition, conventional customized cosmetic manufacturing devices had the problem of requiring a very long time to manufacture the cosmetic desired by the user. Prior art literature

[0038] Additionally, the cosmetic manufacturing device (10) may further include a driving unit (not shown in the drawing) that provides pressure for the formulation to flow along a microchannel (P) formed in the microfluidic chip (400); and a control unit (not shown in the drawing) that controls the pressure of the driving unit (not shown in the drawing) according to the type of microfluidic chip (400).

[0039] Here, the types of microfluidic chips (400) can be classified according to the amount of formulation, components, and viscosity dissolved in the fluid contained in the microfluidic chip, and the types of microfluidic chips (400) may be stored in advance in a database (not shown in the drawing) embedded in the main body (300).

[0040] The cosmetic manufacturing device (10) of the present embodiment may include a storage unit for storing one or more fluids and one or more formulations provided to a microfluidic chip (400) dissolved by the same.

[0041] In this embodiment, the invention is described by way of example as being provided with a storage unit that stores two types of fluids (a first fluid and a second fluid) respectively, and two types of formulations (a first formulation (D1) and a second formulation (D2)) that are dissolved in the two types of fluids (a first fluid and a second fluid) respectively. However, the concept of the invention is not limited thereto and may include three or more types of fluids and three or more types of formulations that are dissolved in them respectively.

[0042] The cosmetic manufacturing device (10) of the present embodiment can produce various cosmetic products depending on the type of microfluidic chip (400).

[0043] A microfluidic chip (400) is provided interchangeably in a cosmetic manufacturing device (10), and various types of formulations can be placed in the microfluidic chip (400) to produce various cosmetic products (e.g., emulsions).

[0044] The cosmetic product produced in this embodiment may include an emulsion in which a fluid and a dissolved formulation are mixed and emulsified, a cosmetic water in which a fluid and a dissolved formulation are solubilized, and a mixed water in which a fluid and a dissolved formulation are simply mixed.

[0045] In this embodiment, a first formulation (D1) and a second formulation (D2) are placed on a microchannel (P) as a type of microfluidic chip (400), and this is explained as an example.

[0046] The storage unit (100) may include a first storage unit (110) for storing a first fluid; and a second storage unit (120) for storing a second fluid which is a different type of fluid from the first fluid. Here, in this embodiment, the first fluid is provided as water as a hydrophilic fluid and the second fluid is provided as oil as a hydrophobic fluid, as an example.

[0047] The capacity of the first storage unit (110) and the second storage unit (120) may each be a capacity in which the first fluid and the second fluid are both discharged in a single operation. However, the concept of the present invention is not limited thereto, and the capacity of the first storage unit (110) and the second storage unit (120) may each include a capacity in which the first fluid and the second fluid are both discharged in multiple operations.

[0048] In addition, the first storage unit (110) and the second storage unit (120) may also be provided interchangeably.

[0049] A connecting part (200) connecting the microfluidic chip (400) and the storage part (100) may be provided on the lower side of the storage part (100).

[0050] Specifically, a first coupling part (210) may be provided on the lower side of the first storage part (110) to connect the first fluid inlet port (411) of the microfluidic chip (400) and the first storage part (110) to transfer the first fluid stored in the first storage part (110) to the microfluidic chip (400) microchannel (P).

[0051] Additionally, a second coupling part (220) may be provided on the lower side of the second storage part (120) to connect the second fluid inlet port (412) of the microfluidic chip (400) with the second storage part (120) and to transfer the second fluid stored in the second storage part (120) to the microfluidic channel (P) of the microfluidic chip (400).

[0052] A microfluidic chip (400) may be placed on the lower side of the coupling portion (200).

[0053] The first coupling section (210) may include a first coupling channel (212), a second coupling channel (214), a third coupling channel (216), and a fourth coupling channel (218) connected to the first storage section (110).

[0054] Specifically, the first connecting channel (212) can be connected to the first upper inlet (411a) of the microfluidic chip (400), the second connecting channel (214) can be connected to the second upper inlet (411b) of the microfluidic chip (400), the third connecting channel (216) can be connected to the first lower inlet (411c) of the microfluidic chip (400), and the fourth connecting channel (218) can be connected to the second lower inlet (411d) of the microfluidic chip (400).

[0055] Additionally, the second coupling portion (220) can be coupled to the second fluid inlet (412) of the microfluidic chip (400).

[0056] In this embodiment, the first fluid stored in the first storage unit (110) is discharged into the microchannel (P) of the dissolution unit (410) through four combined channels (112, 114, 116, 118), and the second fluid stored in the second storage unit (120) is discharged into the microchannel (P) of the dissolution unit (410) through one combined channel (220). However, the number of combined channels of the present invention is not limited thereto.

[0057] In this embodiment, the microfluidic chip (400) and the coupling part (200) coupled thereto may be arranged orthogonally to each other.

[0058] That is, the microchannel (P) of the microfluidic chip (400) and the coupling part (200) can form an angle of 90 degrees.

[0059] For example, the microchannel (P) of the microfluidic chip (400) may be positioned parallel to the bottom surface (XY plane) of the main body (300) while inserted into the main body (300), and the coupling part (200) may be positioned perpendicular to the bottom surface of the main body (300) (Z-axis direction).

[0060] However, the concept of the present invention is not limited thereto, and the microfluidic chip (400) and the coupling part (200) may be arranged in parallel.

[0061] Specifically, the microchannel (P) of the microfluidic chip (400) is arranged in the direction of gravity (Z-axis direction), so that the fluid introduced into the dissolution section (410) of the microfluidic chip (400) can be mixed and emulsified by gravity and then discharged to the outside through the discharge hole (444) of the discharge section (440). In this case, the fluid can be mixed and emulsified by gravity without a driving unit.

[0062] The main body (300) may include a first main body (310) having a first insertion opening (not shown in the drawing) formed therein, which provides a space for inserting a microfluidic chip (400); and a second main body (320) having a second insertion opening (130) formed therein, which provides a space for inserting a storage unit (100).

[0063] In this embodiment, the first body (310) and the second body (320) are described separately, but the first body (310) and the second body (320) may be a single member formed integrally.

[0064] A first insertion port (not shown in the drawing) into which a microfluidic chip (400) can be inserted may be formed in the first main body (310). Here, the first insertion port (not shown in the drawing) may be a space into which a microfluidic chip (400) can be inserted.

[0065] Additionally, on one side of the main body (300), an operating button (330) may be provided to start the operation of forming an emulsion by mixing and emulsifying the fluid stored in the storage unit (100) with the formulation placed in the microfluidic chip (400) after it has been transferred to the microfluidic chip (400).

[0066] Additionally, a recognition part (not shown in the drawing) capable of recognizing the type of microfluidic chip (400) may be provided in the first insertion port (not shown in the drawing) of the main body (300).

[0067] When the type of microfluidic chip (400) is recognized by the recognition unit (not shown in the drawing), the driving unit (not shown in the drawing), which is controlled by the control unit (not shown in the drawing), can apply pressure corresponding to the type of microfluidic chip (400) to the microchannel (P).

[0068] A second insertion opening (130) into which the first storage unit (110) and the second storage unit (120) are inserted may be formed in the second main body (320).

[0069] In this embodiment, the second insertion opening (130) is shown as being formed as a single space. However, the concept of the present invention is not limited thereto, and the second insertion opening (130) may be formed as a plurality of spaces to accommodate the first storage unit (110) and the second storage unit (120), respectively.

[0070] The second main body (320) can be positioned above the first main body (310).

[0071] The microfluidic chip (400) can be provided so as to be detachable from the main body (300).

[0072] The microfluidic chip (400) is provided for separate sale, so that different types of emulsions can be formed by exchanging only the microfluidic chip (400).

[0073] Here, an emulsion can be understood as a cosmetic product that can be applied to a user's skin.

[0074] The cosmetic product manufactured by the cosmetic manufacturing device (10) of the present embodiment may include an O / W (Oil in Water) emulsion manufactured by uniformly dispersing a hydrophobic fluid, such as oil, in a small particle state within a hydrophilic fluid, such as water, or a W / O (Water in Oil) emulsion manufactured by uniformly dispersing a hydrophilic fluid in a small particle state within a hydrophobic fluid.

[0075] The microfluidic chip (400) detachably provided to the cosmetic manufacturing device (10) of the present embodiment can be provided in various ways so that emulsions having different efficacy can be produced.

[0076] For example, the microfluidic chips (400) are provided in a plurality of interchangeable units for the main body (300), and the formulations (e.g., a first formulation (D1) and a second formulation (D2)) placed on the plurality of microfluidic chips (400) may be provided to have different components.

[0077] Additionally, the microchannels (P) formed in the plurality of microfluidic chips (400) can be formed to have different structures depending on the formulation placed in the microfluidic chips (400).

[0078] In this embodiment, the structure of a microchannel (P) of one type of microfluidic chip (400) and a formulation disposed therein are described by way of example.

[0079] Multiple formulations can be placed on the microchannel (P) of the microfluidic chip (400).

[0080] In this embodiment, the microfluidic chip (400) is described by way of example in which a first formulation (D1) that dissolves in a first fluid and a second formulation (D2) that dissolves in a second fluid are arranged.

[0081] Here, the first formulation (D1) is a water-soluble substance and can be formed as a solid (e.g., a powder block) or a gel.

[0082] Additionally, the second formulation (D2) is a substance soluble in oil and can be formed as a solid (e.g., a powder block) or a gel.

[0083] However, the first formulation (D1) and the second formulation (D2) are not limited thereto and may include a liquid wrapped in a solid or gel form. In this case, the solid or gel form wrapping the liquid may be dissolved in the first fluid and the second fluid, respectively, so that the first fluid and the first formulation (D1) are mixed, or the second fluid and the second formulation (D2) are mixed.

[0084] The microchannel (P) of the microfluidic chip (400) can be formed to have different structures depending on the first formulation (D1) and the second formulation (D2) included in the microfluidic chip (400).

[0085] For example, the first fluid and the first formulation (D1) dissolved in the first fluid may include water, polyol, thickener, surfactant, auxiliary emulsifier, humectant, salts, preservative, functional raw material dissolved in an aqueous phase (e.g., water).

[0086] Here, polyols can be understood as polyfunctional alcohols having two or more hydroxyl groups (-OH) in the molecule. Polyols may include glycol having two hydroxyl groups, glycerol having three hydroxyl groups, and pentaerythritol having four hydroxyl groups.

[0087] For example, the polyol may include one or more substances selected from the group consisting of ethylene glycol, propylene glycol, dipropylene glycol, 1,3-butylene glycol, diglycerin, 1,3-propanediol, glycerin, methylpropanediol, ethylhexanediol, 1,2-hexanediol, isoprene glycol, ethyl alcohol, pentylene glycol, and isopentyldiol.

[0088] Thickeners include gelatin, gellan gum, guar gum, xanthan gum, locust bean gum, alginic acid, arabic gum, carrageenan, pectin, cellulose, mannan, carbomer, sodium polyacrylate, polyacrylic acid, polyacrylate crosspolymer, hydroxyethyl acrylate / sodium acryloyldimethyl taurate copolymer, and ammonium acryloyldimethyl taurate / VP copolymer. It may include one or more substances selected from the group consisting of acryloyldimethyltaurate / vp copolymer), sodium polyacryloyldimethyl taurate, acrylate / C10-30 alkyl acrylate crosspolymer, ammonium acryloyldimethyltaurate / beheneth-25 methacrylate crosspolymer, polyvinyl alcohol, and glyceryl acrylate / acrylic acid copolymer.

[0090] In addition, for example, the second fluid and the second formulation (D2) dissolved in the second fluid may include oil, a surfactant, an auxiliary emulsifier, a functional raw material dissolved in oil, etc.

[0091] In addition, at least one of the first fluid, the first formulation (D1) dissolved in the first fluid, the second fluid, and the second formulation (D2) dissolved in the second fluid may include at least one of a humectant, a surfactant, a thickening agent, and an auxiliary emulsifier.

[0092] Humectants include trehalose, fructose, sucrose, sorbitol, maltitol, panthenol, raffinose, urea, betaine, glycereth-26, methylgluceth-20, PEG-8, PEG-32, PEG-75, PEG / PPG / polybutylene glycol-8 / 5 / 3 glycerin, ethylene glycol, propylene glycol, dipropylene glycol, 1,3-butylene glycol, and diglycerin. It may include one or more substances selected from the group consisting of 1,3-propanediol, glycerin, methylpropanediol, ethylhexanediol, 1,2-hexanediol, isoprene glycol, ethyl alcohol, pentylene glycol, and isopentyldiol.

[0093] The surfactants are Sorbitan Monostearate, Sorbitan Sesquioleate, Polysorbate 20, Polysorbate 60, Polysorbate 80, PEG-40 Stearate, PEG-100 Stearate, PEG-60 Glyceryl Isostearate, PEG-75 Stearate, Ceteth-20, Steareth-20, Cetearyl Glucoside, Arachidyl Glucoside, and Lauryl Lauryl Glucoside, Sucrose Polystearate, Sucrose Laurate, Polyglyceryl-3 Methylglucose Distearate, Polyglyceryl-10 Stearate, Lecithin, Sodium Stearoyl Glutamate, Glyceryl Stearate Citrate, Potassium Cetyl Phosphate, Sodium Methyl Stearoyl Taurate, Inulin Lauryl Carbamate, Ceteareth-12, PEG-5 Rapeseed Sterol Rapeseed Sterol), Methoxy PEG-114 / Polyepsilon Caprolactone,Cetyl PEG / PPG 10 / 1 Dimethicone Triglyceride, PEG-10 Dimethicone, Lauryl PEG-9 Polydimethylsiloxyethyl Dimethicone, Polyglyceryl-2 Dipolyhydroxystearate, PEG-60 Hydrogenated Castor Oil, PEG-30 Hydrogenated Castor Oil, Octyldodeceth-16, Octyldodeceth-25, Bis-PEG-18 It may include one or more substances selected from the group consisting of methyl ether dimethyl silane (Bis-PEG-18 Methyl Ether Dimethyl Silane), polyglyceryl-6 caprylate, and polyglyceryl-4 caprate.

[0094] The auxiliary emulsifier may include one or more substances selected from the group consisting of cetearyl alcohol, cetyl alcohol, stearyl alcohol, behenyl alcohol, glyceryl stearate, and stearic acid.

[0095] However, this is merely an exemplary component, and the types of raw materials included in the first fluid, the first formulation (D1) dissolved in the first fluid, the second fluid, and the second formulation (D2) dissolved in the second fluid are not limited. The first fluid, the first formulation (D1) dissolved in the first fluid, the second fluid, and the second formulation (D2) dissolved in the second fluid pass through the microchannel (P) formed in the dissolution section (410), mixing section (420), emulsification section (430), and discharge section (440) of the microfluidic chip (400), and are mixed and emulsified to form an O / W emulsion or a W / O emulsion.

[0096] The microfluidic chip (400) can receive a first fluid from a first storage unit (110) and a second fluid from a second storage unit (120).

[0097] On the microchannel (P) of the microfluidic chip (400), the first fluid dissolves the first formulation (D1) and the second fluid dissolves the second formulation (D2), and then the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) are mixed and emulsified to form an emulsion, after which it can be discharged outside the microfluidic chip (400).

[0098] Specifically, the type of emulsion (e.g., W / O emulsion or O / W emulsion) can be determined according to the ratio of the first fluid and the second fluid supplied from the storage unit (100) to the microfluidic chip (400).

[0099] The ratio of the first fluid and the second fluid supplied to the microfluidic chip (400) can be adjusted by the discharge amount of the first fluid and the second fluid discharged from the first storage unit (110) and the second storage unit (120), and the discharge amount of the first fluid and the second fluid can be controlled by a control unit (not shown in the drawing).

[0100] For example, if the supply amount of the first fluid, water, is greater than the supply amount of the second fluid, oil, an O / W emulsion is formed, and if the supply amount of the second fluid, oil, is greater than the supply amount of the first fluid, water, a W / O emulsion is formed.

[0101] The microfluidic chip (400) may be a plate having a microchannel (P) formed therein through which fluid can flow.

[0102] The microfluidic chip (400) is provided as a single layer in the shape of a flat plate, and a microchannel (P) can be formed inside. By arranging the microchannel (P) on a single flat plate in this way, the cosmetic manufacturing device (10) can be miniaturized.

[0103] The cross-section of the microchannel (P) formed inside the microfluidic chip (400) may be rectangular, in which case the average length of each side may be between 0.5 mm and 1 mm. If the microchannel (P) has a circular cross-section, the average length of the diameter may be between 0.5 mm and 1 mm.

[0104] When a microchannel (P) is formed inside the microfluidic chip (400), the fluid flow rate increases, thereby increasing the efficiency of mixing and emulsification.

[0105] Meanwhile, in the present embodiment, the microchannels (P) formed in the microfluidic chip (400) can substantially form a single-layer path. A single-layer path can be understood as a path in which a height difference of the channel is not involved in the mixing and emulsification process of each fluid or the emulsification process of the mixed fluid.

[0106] The single-layer path of the present embodiment may correspond to a first microchannel (P1), a second microchannel (P2), a mixing channel (421), a vortex-forming channel (431), and an exhaust channel (442) implemented on a single flat plate.

[0107] The microfluidic chip (400) may include a dissolution section (410), a mixing section (420), an emulsification section (430), and a discharge section (440).

[0108] The dissolution section (410) may include a first fluid inlet (411) into which a first fluid is introduced; a second fluid inlet (412) into which a second fluid is introduced; a first formulation (D1) disposed in a first microchannel (P1) through which the first fluid flows and dissolved by the first fluid; a second formulation (D2) disposed in a second microchannel (P2) through which the second fluid flows and dissolved by the second fluid; and a confluence section (414) where the first formulation (D1) dissolved by the first fluid and the second formulation (D2) dissolved by the second fluid meet.

[0109] Here, the width (W1) of the microchannel (first microchannel (P1)) in which the first formulation (D1) is placed and the width (W2) of the microchannel (second microchannel (P2)) in which the second formulation (D2) is placed can be formed to be larger than the width of the other microchannel (P).

[0110] By doing so, the contact area between the first formulation (D1) and the first fluid and the contact area between the second formulation (D2) and the second fluid can be increased, allowing the first formulation (D1) and the second formulation (D2) to be easily dissolved.

[0111] The first formulation (D1) can be fixed on the first microchannel (P1), and the second formulation (D2) can be fixed on the second microchannel (P2).

[0112] A first formulation (D1) may be placed in the first microchannel (P1), and the first fluid may pass through the first gap channel (P11) formed between the first microchannel (P1) and the first formulation (D1) while dissolving the first formulation (D1) (see FIG. 3).

[0113] A second formulation (D2) may be placed in the second microchannel (P2), and the second fluid may pass through the second interstitial channel (P21) formed between the second microchannel (P2) and the first formulation (D1) while dissolving the second formulation (D2).

[0114] The width (C1) of the first gap channel (P11) can be formed smaller than the width of the first microchannel (P1), and the width (C2) of the second gap channel (P21) can be formed smaller than the width of the second microchannel (P2).

[0115] As the first formulation (D1) dissolves in the first fluid, the width (C1) can increase, and as the second formulation (D2) dissolves in the second fluid, the width (C2) can increase.

[0116] As the width (C1) of the first gap channel (P11) and the width (C2) of the second gap channel (P21) increase, the pressure applied to the microchannel (P) of the microfluidic chip (400) by the driving unit (not shown in the drawing) can be increased. At this time, the driving unit (not shown in the drawing) can be controlled by the control unit (not shown in the drawing).

[0117] That is, a gap channel through which fluid can flow can be formed between the microchannel (P) and the formulation, and as the formulation is dissolved by the fluid, the width of the gap channel can be increased, and as the width of the gap channel increases, the pressure applied to the microchannel (P) can be increased.

[0118] The mixing section (420) may include a mixing channel (421) in which a first fluid, a dissolved first formulation (D1), a second fluid, and a dissolved second formulation (D2) are mixed.

[0119] The mixing channel (421) can be formed in a zigzag shape.

[0120] Specifically, the mixing channel (421) may include a first mixing channel (4211) formed to extend in one direction from a microchannel (P) formed in the melting section (410); a second mixing channel (4212) bent by a preset angle (e.g., 90 degrees) from the first mixing channel (4211); and a third mixing channel (4213) bent by a preset angle (e.g., 90 degrees) from the second mixing channel (4212).

[0121] Here, the first mixing channel (4211) and the third mixing channel (4213) can be formed in parallel.

[0122] Here, the width (W3) of the first mixing channel (4211) and the width (W5) of the third mixing channel (4213) may increase and then decrease along the direction of fluid flow, and the width (W4) of the second mixing channel (4212) may be formed at a constant value.

[0123] The mixing section (420) of the present embodiment may include a plurality of first mixing channels (4211), a plurality of second mixing channels (4212), and a plurality of third mixing channels (4213). Specifically, the mixing section (420) may be formed with three first mixing channels (4211), four second mixing channels (4212), and two third mixing channels (4213).

[0124] The emulsification section (430) may have a plurality of vortex-forming channels (431) formed by changing the direction of flow of the fluid so that the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) can be emulsified to form an emulsion.

[0125] Here, emulsification can be understood as a technique of dispersing one of two immiscible fluids, such as water and oil, into small particles and placing them in a stable state within the other fluid.

[0126] The vortex-forming channels (431) may be formed continuously in a plurality of the first region (A1) of the emulsification section (430) and may be formed continuously in a plurality of the second region (A2) located at the bottom of the first region (A1).

[0127] The vortex-forming channel (431) formed in the first region (A1) and the vortex-forming channel (431) formed in the second region (A2) can be connected through a connecting channel (432), and the connecting channel (432) can be formed as a straight channel.

[0128] In this embodiment, the vortex-forming channel (431) is described as being configured to rotate the incoming fluid in one direction (counterclockwise in this embodiment based on the drawing) and then rotate it in the other direction (clockwise in this embodiment based on the drawing).

[0129] Specifically, each vortex-forming channel (431) may include a first rotation channel (4311) that guides the incoming fluid to rotate in one direction; a second rotation channel (4312) that guides the fluid rotating in one direction to rotate in another direction; and a direction change channel (4313) that changes the rotation direction of the fluid between the first rotation channel (4311) and the second rotation channel (4312).

[0130] Here, emulsification can proceed as the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) pass through a plurality of vortex-forming channels (431).

[0131] The external fluid (the first fluid and dissolved first formulation (D1), or the second fluid and dissolved second formulation (D2)) and the internal fluid (the second fluid and dissolved second formulation (D2), or the first fluid and dissolved first formulation (D1)) may be thinned or broken by the formation of vortices as they pass through the vortex-forming channel (431).

[0132] By repeating this process, an emulsion can be formed in which the finely fragmented internal fluid exists stably within the external fluid.

[0133] The discharge section (440) can be extended from the emulsification section (430).

[0134] The discharge section (440) may include a discharge channel (442) extending from the vortex-forming channel (431) of the emulsification section (430); and a discharge hole (444) through which the generated emulsion is discharged.

[0135] The discharge channel (442) can be formed to extend in one direction after being bent at a predetermined angle (e.g., 90 degrees) from the vortex-forming channel (431).

[0136] The discharge channel (442) may include a portion that extends from the vortex-forming channel (431) toward the discharge hole (444) and increases in width.

[0137] The discharge section (440) can be formed at one end of the discharge channel (442).

[0138] The above-described first microchannel (P1), second microchannel (P2), second fluid inlet (412), mixing channel (421), vortex-forming channel (431) and discharge channel (442) can be understood as microchannels (P) formed in the microfluidic chip (400).

[0139] Additionally, the cosmetic manufacturing device (10) may further include a cosmetic container (500) positioned below the discharge hole (444) of the microfluidic chip (400).

[0140] The cosmetic container (500) can store the emulsion discharged from the discharge hole (444).

[0141] Additionally, the cosmetic container (500) may be provided to be selectively fixed to the microfluidic chip (400).

[0142] Specifically, the inlet of the cosmetic container (500) and the discharge hole (444) of the microfluidic chip (400) are aligned, and the inlet of the cosmetic container (500) and the discharge hole (444) can be fixed to each other.

[0143] In this case, while the emulsion is being discharged from the microfluidic chip (400), the cosmetic container (500) and the microfluidic chip (400) remain in a fixed state, and when the discharge of the emulsion from the microfluidic chip (400) is completed, the cosmetic container (500) can be removed from the microfluidic chip (400).

[0144] Additionally, the cosmetic manufacturing device (10) may further include a driving unit (not shown in the drawing) that provides pressure for the fluid and the formulation dissolved in the fluid to flow along a microchannel (P) formed in a microfluidic chip.

[0145] Specifically, the driving unit can provide pressure for the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) to flow along the microchannel (P).

[0146] The driving unit can apply pressure toward the microchannel (P) formed along the discharge hole (444) from the first fluid inlet (411) and the second fluid inlet (412).

[0147] The driving unit can apply pressure from the first fluid inlet (411) and the second fluid inlet (412) to the discharge hole (444) along the microchannel (P) by introducing air into the first fluid inlet (411) and the second fluid inlet (412).

[0148] Additionally, the cosmetic manufacturing device (10) may further include a control unit (not shown in the drawing) that controls the pressure applied from the driving unit to the microfluidic chip (400) in the microchannel (P).

[0149] The control unit (not shown in the drawing) can control the flow velocity of the fluid flowing along the microchannel (P).

[0150] Specifically, the control unit (not shown in the drawing) can control the flow rate of the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) flowing along the mixing channel (421) of the mixing unit (420), and can control the flow rate of the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) flowing along the vortex-forming channel (431) of the emulsifying unit (430).

[0151] The control unit (not shown in the drawing) can control the pressure applied to the microchannel (P) differently depending on the type of microfluidic chip (400).

[0152] For example, when a first type of microfluidic chip (400) is provided, a control unit (not shown in the drawing) can apply a first pressure to the microchannel (P), and when a second type of microfluidic chip (400) is provided, a control unit (not shown in the drawing) can apply a second pressure to the microchannel (P).

[0153] Here, the first type of microfluidic chip (400) may include a first formulation (D1) containing a first component and a second formulation (D2) containing a second component, and the second type of microfluidic chip (400) may include a first formulation (D1) containing a third component and a second formulation (D2) containing a fourth component. Here, the first component, the second component, the third component, and the fourth component may be different components.

[0154] Additionally, the control unit (not shown in the drawing) can control the amount of the first fluid stored in the first storage unit (110) discharged to the microfluidic chip (400) and the amount of the second fluid stored in the second storage unit (120) discharged to the microfluidic chip (400).

[0155] The following describes the operation process of the cosmetic manufacturing device (10).

[0156] A control method for a cosmetic manufacturing device according to the present embodiment comprises: a step (S1) in which a type of microfluidic chip (400) is inserted into a main body (300); a step (S2) in which, after the type of the microfluidic chip (400) is recognized by a recognition unit (not shown in the drawing), a preset pressure corresponding to the type of the microfluidic chip is applied to a microchannel (P) by a driving unit (not shown in the drawing); a step (S3) in which a first fluid dissolves a first formulation (D1) placed in a dissolution unit (410), and a second fluid dissolves a second formulation (D2) placed in a dissolution unit (410), and then they merge at a confluence unit (414); and a step (S4) in which the first fluid, the dissolved first formulation (D1), the second fluid, and the dissolved second formulation (D2) proceed along a mixing channel (421) formed in a mixing unit (420) and are mixed. The method may include a step (S5) in which a first fluid, a dissolved first formulation (D1), a second fluid, and a dissolved second formulation (D2) proceed along a vortex-forming channel (431) formed in an emulsification section (430) and are mixed to form a cosmetic; and a step (S6) in which the cosmetic is discharged to the outside along a discharge hole (444) of a discharge section (440).
