Description

Instant emulsion cosmetic manufacturing device {APPARATUS FOR MANUFACTURING COSMETIC USING INSTANTANEOUS EMULSIFICATION}

The present invention relates to an apparatus for manufacturing instant emulsified cosmetics.

Fluid emulsification technology refers to a technology of dispersing one of two immiscible fluids, such as water and oil, into small particles and placing it in a stable state in the other liquid. Such emulsification technology is widely used in the manufacturing field of cosmetics such as lotion, cream, essence, massage cream, cleansing cream, makeup base, foundation, eyeliner, mascara, and the like.

Specifically, cosmetics are O / W (Oil in Water) emulsion (emulsion, emulsion) prepared by uniformly dispersing a hydrophobic fluid such as oil in a hydrophilic fluid such as water in a state of small particles or a hydrophilic fluid in a hydrophobic fluid with small particles. It may include a W/O (Water in Oil) emulsion prepared by uniformly dispersing in the state. In the manufacturing process of such an emulsion, a surfactant or a thickener is used for the purpose of improving productivity and product quality. In addition, functional raw materials such as vitamins may be further added to the emulsion in order to improve the efficacy as a cosmetic.

In order to produce an emulsion, it is necessary to properly mix the internal trauma fluid, which is dispersed as fine particles, and the external fluid, which is a continuous phase surrounding the fine particles, with each other. The emulsion is mass-produced in advance and then commercialized and sold.

However, the prior art as described above has the following problems.

Cosmetics, including emulsions, can only be used by consumers by being manufactured, packaged, transported, and then sold at online and offline stores. That is, it takes a long time from the time of manufacture of the emulsion to the time of actual use. In the market, consumers' desire for fresh cosmetics is increasing, but the conventional manufacturing and sales methods cannot satisfy the consumer's desire.

In addition, the demand for cosmetics to which preservatives are not added has recently increased.

However, there is a problem that cosmetics to which preservatives are not added cannot be stored for a long period of time, and preservatives must be added to cosmetics that can be stored for a long period of time to prevent deterioration. In particular, water-based cosmetic raw materials require a preservative as a favorable environment for microorganisms to grow. That is, conventional cosmetics have a problem in that they cannot satisfy consumer's desire for cosmetics to which preservatives are not added.

In addition, consumers prefer products in which additional substances such as surfactants and thickeners, which are chemical substances that are not significantly related to the original function of cosmetics, are minimized, and the stability of the product is maintained for a long time expected from manufacturing to use. In order to do this, there is a problem that an additional material has to be used over a certain level.

However, the shapes of the pressing parts 23 , 33 , 43 , and 44 are not limited thereto, and may have various shapes such as a cylindrical shape and a rectangular parallelepiped shape.

In the embodiment of the present invention, it is exemplified that the plate 12 on which the channel part 100 is formed applies pressure to the pressurizing part 23, and discharges the fluid stored in the storage parts 21,31,41,51 of each container. However, it may include a separate pump. For example, a pump that forms a pressure so that the acidic fluid, the basic fluid, and the functional fluid and the internal fluid selectively provided can be discharged to the discharge unit 18 via the channel unit 100 is located in the housing 10 . may be provided separately.

The channel part 100 may be formed on the plate 12 . 3 illustrates that each of the channels 110 and 120 is formed on one plate 12, after the channels 110 and 120 are formed on a plurality of plates, they may be stacked up and down.

The channel part 100 is connected to the first container 20, the second container 30, and the fourth container 50, and a first channel 110 in which the fluid from each container can be mixed, and the first It may include a second channel 120 that is mixed with the fluid supplied from the channel 110 and the inner fluid supplied from the third container (40). Here, the first channel 110 and the second channel 120 may be understood as microfluidic channels.

The first channel 110 and the second channel 120 may be understood as predetermined flow paths through which the fluid entering the channel can move, and may be formed inside the plate 12 as in the present embodiment. However, the method of providing the first channel 110 and the second channel 120 is not limited thereto, and according to an embodiment, the first channel 110 and the second channel 120 are integrally formed to form a flow path. may be or may be formed by assembling a plurality of parts including a flow path with each other.

In addition, the plate 12 may be provided transparently so that the fluid flowing in the first channel 110 and the second channel 120 can be seen. Here, it can be understood that the first channel 110 and the second channel 120 are formed inside the plate 12 .

The first channel 110 mixes an acidic fluid that forms a trauma fluid supplied from the first container 20 and a basic fluid that forms a trauma fluid supplied from the second container 30 to generate a neutralized internal trauma fluid. .

Here, the pH of the neutralized internal injury fluid may be understood to be between 4 and 8. In addition, the pH of the final emulsion after the neutralized internal fluid and the internal fluid supplied from the second channel 120 are mixed may be understood to be between 4 and 8.

In addition, the pH of the optionally provided functional fluid may be provided between 4 and 8, similarly to the pH of the final emulsion.

The first channel 110 is a first junction 115 where the acidic fluid and the basic fluid meet each other, and the acidic fluid and the basic fluid met at the first junction 115 are mixed to form a neutralized trauma fluid. A connection part 119 for providing the neutralized fluid generated in the part 117 and the mixing part 117 to the second channel 120 may be included. That is, the first channel 110 may be understood as a region from the point where the acidic fluid and the basic fluid are introduced to the connection part 119 .

In addition, the first channel 110 is connected to the acidic fluid inlet 111 connected to the first container 20 , the basic fluid inlet 112 connected to the second container 30 , and the fourth container 50 . The functional fluid inlet 113, the acidic fluid coming out of the acidic fluid inlet 111 and the basic fluid coming out of the basic fluid inlet 112 and the functional fluid coming out of the functional fluid inlet 113 meet 115, a first junction 115, The first confluence unit 115 may include a mixing unit 117 for generating a mixed fluid while allowing the acidic fluid, the basic fluid, and the functional fluid to proceed together. Here, four or more mixing units 117 may be formed to more effectively mix each fluid.

In addition, the first channel 110 connects the acidic fluid flow path 114 between the acidic fluid inlet 111 and the first confluence 115 , and between the basic fluid inlet 112 and the first confluence 115 . It may include a basic fluid flow path 115 that connects, and a functional fluid flow path 116 that connects between the functional fluid inlet 113 and the first confluence part 115 .

The mixing unit 117 is a flow path capable of forming a vortex in the flow by changing the flow direction of the fluid. To this end, the mixing part 117 may include a bent part, a bent part, a rotating part, etc. so that the flow direction of the fluid can be switched.

In particular, when the mixing unit 117 is formed to rotate the fluid in one or both directions, a centrifugal force is applied to the fluid and at the same time forming a vortex in the flow of the fluid, the fluid passing through the mixing unit 117 is enough to be mixed.

In this embodiment, it will be described as an example that the mixing unit 117 is configured to rotate the entering fluid in one direction (counterclockwise based on the drawing) and then rotate it again in the other direction (clockwise based on the drawing). Specifically, the mixing unit 117 includes a first rotation path 1171 guiding the fluid to be rotated in one direction, a second rotation path 1172 guiding the fluid rotating in one direction to be rotated in the other direction, and a second A direction change path 1173 for changing the rotation direction of the fluid between the first rotation path 1171 and the second rotation path 1172 may be included.

By this mixing unit 117, the acidic fluid, the basic fluid, and the functional fluid move along the first rotational path 1171, rotate in one direction, and are mixed, and after the rotational direction is changed in the direction changing path 1173 Since it is rotated and mixed again in the other direction, each fluid can be mixed effectively. In addition, although in this embodiment four mixing units 117 are continuously arranged on the first channel 110 as an example, the number and arrangement of the mixing units 117 are not limited to the spirit of the present invention. .

On the other hand, in the present embodiment, the mixing unit 117 has been described as an example to promote mixing by changing the flow direction of the fluid to form a vortex, but the method of mixing the fluid is not limited thereto. A method of increasing the contact area, a method of applying an electric field, a method using sound waves, and other various methods capable of causing agitation in the microfluidic channel may be used.

Although the above-described embodiment illustrates that all of the acidic fluid, the basic fluid, and the functional fluid are provided, the functional fluid may be selectively added. In this case, the functional fluid inlet 113 and the functional fluid flow path 116 may be excluded.

In addition, when the functional fluid is provided, one or more fourth containers for storing the functional fluid may be provided. For example, three fourth containers may be provided, and a functional fluid suitable for a user's preference may be provided to each fourth container.

As it passes through the mixing unit 117, the acidic fluid and the basic fluid are sufficiently mixed, and the mixed fluid may be referred to as a neutralized fluid in this embodiment. Alternatively, acidic fluids and basic fluids may be understood as neutralized trauma fluids as forming trauma fluids.

In addition, the acidic fluid and the basic fluid may be cosmetic fluids based on water as the trauma fluid. Essentially, water-based cosmetics are an environment in which microorganisms are likely to grow. However, it is possible to provide cosmetics without added preservatives by forming the water-based cosmetic raw material under conditions in which it is difficult for microorganisms to grow while making the pH under acidic and basic conditions.

In addition, when a functional fluid is additionally provided, a solution in which an acidic fluid, a basic fluid, and a functional fluid are mixed may also be understood as a neutralized solution in terms of pH. Such a solution may also be referred to as a neutralized mixed liquid. In an embodiment of the present invention, the pH of the neutralized solution may be understood to be between 4 and 8.

The second channel 120 stirs the neutralized trauma fluid supplied from the first channel 110 and the internal trauma fluid supplied from the third container 40 to generate an emulsion, which is an emulsifying material.

Here, the neutralized fluid containing the trauma fluid and the internal trauma fluid may be emulsified for a very short time passing through the second channel 120 to become an emulsion. That is, the neutralized fluid and the internal fluid may be instantly emulsified. At this time, the neutralized fluid is instantaneously emulsified in the second channel 120 , and the internal injury fluid may be dispersed in a particle state between the trauma fluid and the functional fluid.

The second channel 120 is a second confluence part where the neutralized trauma fluid supplied from the connection part 119 of the first channel 110 and the internal injury fluid inlet 121 connected to the third container 40 meets the internal injury fluid. (123), an emulsifying unit 126 for generating an emulsion by emulsifying the neutralized trauma fluid and internal trauma fluid met at the second confluence unit 123, and discharging the emulsion generated in the emulsifying unit 126 to the outside It may include an external discharge port 126 .

Here, the path from the inner fluid inlet 121 to the second junction 123 may form various types of paths such as curved lines and straight lines.

The emulsifying part 126 cuts off the flow of the fluid in which the internal fluid is neutralized, and allows the internal fluid to be dispersed in the neutralized fluid in a particle state. It will be described as an example that an orifice whose width is narrowed in the traveling direction is provided as the emulsifying part 126 . For example, the emulsifying portion 126 is an orifice, and may be formed to have a smaller width than the internal fluid movement path 125 and the discharge path 127 .

In this case, the external discharge port 129 from the discharge path 127 may be formed in the extension portion 13 of the plate 12 .

Here, the extension portion 13 may be understood as a portion extending laterally of the plate 12 on which the channel portion 100 is formed. This part may be understood as not overlapping the housing 10 when the housing 10 is viewed in the vertical direction.

The internal fluid flows through the orifice having a relatively narrow width, and in the direction of narrowing inside the orifice (defined as the vertical direction) and the resultant direction of the fluid flow direction (defined as the horizontal direction) (defined as the diagonal direction that gathers toward the center of the orifice) A shear force is applied to the mixed fluid. Due to this force and the geometry of the corner of the orifice inlet, the moving flow of the mixed fluid is interrupted and becomes a particle shape. When two immiscible fluids pass through an orifice with an unstable interface, capillary instability increases, and a channel with an orifice can break the flow of a mixed fluid with less energy than a channel without an orifice. The broken neutralized trauma fluid takes a spherical shape to maintain a stable state, and the internal trauma fluid is dispersed in the neutralized trauma fluid.

The emulsification method using an orifice as in this embodiment can be referred to as a flow-focusing method emulsification, which allows the fluids of different phases to flow in the same direction, but by locating the orifice at the junction, the flow of the trauma fluid in which the inner wound fluid is neutralized It is designed to be able to disconnect (Flow-Focusing method). If the orifice is used in this way, the flow of the internal trauma fluid changes in a diagonal direction inside the orifice, and a stronger shear force can be transmitted to the neutralized trauma fluid, thereby forming the emulsified particles more easily and at the same time forming the emulsified particles of a certain size. can

In addition, various embodiments may be applied to the emulsifying unit 126 , for example, a method of emulsifying fluids of different phases while moving them in the same direction (Co-Flow method), so that fluids of different phases can intersect. A method of emulsifying while moving (Cross-Flow method), a method of forming emulsified particles at the confluence by adjusting the aspect ratio between the entrance of the trauma fluid to the confluence and the entrance of the inner fluid to be large or low (Step Emulsification method), the inner wound fluid Alternatively, a method of forming emulsified particles by passing a mixed fluid of two phases through a hole of a membrane (Membrane Emulsification method) may be used.

In addition, the emulsifying unit 126 may use a power source, for example, an electric field (Electrical control), a magnetic field (Magnetic control), a centrifugal force (Centrifugal control), a laser (Optical control), a vibrator (Vibration control), Piezoelectric material (Piezoelectric control) A channel of a method of forming emulsified particles using any one or more may be used.

In addition, the emulsifying unit 126 may form emulsified particles by changing the viscosity, interfacial tension, and wettability of the fluid, for example, Electrorheological (ER) or Magnetorheological (MR) Fluids, Photo-sensitive Fluids may be applied.

The emulsion formed in the emulsifying part 126 may pass through the discharge path 127 and be stabilized. Here, the inner wall of the discharge path 127 may be provided to have a property corresponding to the hydrophilicity of the trauma fluid.

In this case, the trauma fluid constituting the trauma of the emulsion is drawn to the inner wall side of the discharge path 127, and the internal trauma fluid is relatively far away from the inner wall side of the discharge path 127, so the emulsion state is stably maintained and moved can be As in the embodiment of the present invention, when the internal fluid is oil, the inner wall of the discharge path 127 may be coated with a film of a hydrophilic material.

Here, as the hydrophilic material or the hydrophilic film, a material having a contact angle with water of 0 to 50 degrees may be used.

Conversely, when oil is used as the internal fluid, the inner wall may be coated with a film of a hydrophobic material, and as the hydrophobic material or the hydrophobic film, a material having a contact angle with water of 70 degrees to 120 degrees may be used.

In addition, according to the embodiment, as well as the discharge path 127, other components of the emulsifying unit 126 and the second channel 120 may be formed to have a property corresponding to the hydrophilicity of the trauma fluid.

Conventionally, since the interfacial tension between the trauma fluid and the internal trauma fluid is high, it is difficult to form and maintain the emulsified particles without using an excess of surfactant (1% to 5%), etc. However, according to the present embodiment, since the effect of the surface force on the fluid in the second channel 120 having a minimum characteristic length (millimeter or less) is significantly greater than that of the body force, a surfactant, etc. It has the advantage that emulsification can be achieved quickly with no use or with a minimal amount of addition. In addition, the principle that one of the two fluids that do not easily mix with each other breaks the flow of the other to form emulsified particles also helps to reduce the surfactant.
