Solid foundation cosmetics having various three-dimensional shapes and methods for manufacturing the same

Various embodiments relate to solid foundation cosmetics having various three-dimensional shapes and methods for manufacturing the same.

Foundation is a cosmetic applied to the face, neck, etc. to evenly cover the skin tone. There are various types of foundations such as liquid foundation, powder foundation, and solid foundation. Among them, solid foundations are, for example, those called skin covers or cover balms.

In general, the solid type foundation includes a water-in-oil type or an oil-in-water type solid foundation in which powder is dispersed in an oil or water phase component, and a dispersion-type solid foundation in which powder is dispersed in an oil phase. Dispersion solid foundation has the advantage of giving high coverage and long-lasting makeup, but because it has a lot of powder, it feels dry on the skin after applying the cosmetic, or it has the disadvantage of expressing unnatural makeup due to the thick makeup film. have. When increasing the powder content of various types in order to increase the finish and the makeup lasting in the dispersion-type solid foundation, the user immediately feels the dryness of the skin immediately after application of the product, or the cosmetic film floats due to keratin on the skin surface, resulting in a smooth makeup expression. It becomes difficult. In addition, there is a disadvantage in that makeup is often unnaturally expressed with a thick makeup film. When the powder content is reduced in the dispersion-type solid foundation, it is difficult to secure stability such as oil separation in the solid foundation, and there are limitations in realizing a smooth finish and lasting makeup.

Therefore, it is necessary to develop a makeup cosmetic composition having an excellent feeling of use and covering power while including powder optimally or family register.

In addition, the existing fact-type dispersion-type solid foundation (eg, skin cover, cover balm) is generally manufactured by pouring contents into a pan made of aluminum to harden. In this case, the solid foundation could only have a flat shape, so there was no difference in appearance.

In order to prepare a solid foundation having a three-dimensional shape, there was no other method than shaping the contents and then picking up and moving the molded contents with a hand or other tool to attach them to a pan or dish of a cosmetic container. In this case, there was a problem in that the contents may be melted or the shape of the contents may be damaged during the moving process. Moreover, a bond was used to attach the molded contents to a dish, in which case there was a problem that the bond could affect the stability and safety of the composition. Therefore, conventionally, due to the problems described above, it has been difficult to manufacture a solid foundation having a three-dimensional shape while maintaining product quality.

The present invention has been devised to improve the above problems, a method for manufacturing a three-dimensional solid foundation and a container capable of being attached to a cosmetic container without impairing the three-dimensional form of the solid foundation without applying an adhesive directly to the solid foundation Want to provide. In addition, it is intended to provide a solid foundation cosmetic composition for preparing such a three-dimensional solid foundation. However, these problems are exemplary, and the scope of the present invention is not limited thereby.

The composition has an effect of being in close contact with the skin while having a smooth feeling of use and stability by including an oil thickener without using wax.

The thickener may be included in 0.1 to 10% by weight of the total composition. For example, 0.1 to 10% by weight, 0.1 to 8% by weight, 0.1 to 6% by weight, 0.1 to 4% by weight, 1 to 8% by weight, 1 to 7% by weight, 1 to 5% by weight, 2 to 9% by weight %, 3 to 8% by weight, 4 to 7% by weight, or 5 to 6% by weight. At this time, if the content of the thickener is less than the above range, there is a problem that it is difficult to sufficiently exhibit the effect of thickening the oily part, and it is difficult to maintain the solid phase. There is a problem that the feeling of use of the cosmetic is lowered.

In one embodiment, the oily thickener may be dibutyl ethylhexanoyl glutamide and dibutyl lauroyl glutamide. The dibutyl ethylhexanoyl glutamide and dibutyl lauroyl glutamide may be mixed in a ratio of 1: 1 to 3: 2. For example, it may be 1: 1 to 3: 2, 1: 1 to 1: 2, 1: 1 to 1: 3, 2: 1 to 3: 1 or 2: 3 to 3: 2. At this time, when the mixing ratio of dibutyl ethylhexanoyl glutamide and dibutyl lauroyl glutamide is less than the above range, there is a problem that the composition is split or broken despite having an appropriate hardness and exceeds the above range, There is a problem that the melting point of the composition is very high, around 120 ° C, making it difficult to handle the formulation.

The composition may be one that does not contain a silicone-based oil. The silicone oil is, for example, dimethicone, phenylpropyl dimethylsiloxysilicate (Phenylpropyldimethylsiloxysilicate, Trimethyl Pentaphenyl Trisiloxane), diphenylsiloxy phenyl trimethicone (Diphenylsiloxy Phenyl Trimethicone), etc. Since the composition does not contain a silicone-based oil, it has the advantage that it can be applied to sensitive skin because it can prevent skin irritation by minimizing skin irritation. Can meet the needs of people

The composition may further include a powder pigment. The powder pigment is, for example, silica, mica / dimethicone, sericit / dimethicone, titanium dioxide, zinc oxide, polymethylsil Polymethylsilsesquioxane, Polymethyl Methacrylate, Talc, Mica, Alumina, Barium sulfate, Magnesium Myristate, Iron Oxide Iron oxide), Nylon-12, HDI / Trimethylol hexyllactone crosspolymer, Methyl Methacrylate Crosspolymer or Kaolin, etc. . The powder pigment may be selected in consideration of UV blocking function, covering power, color and spreadability. In one embodiment, the powder pigment may be a coating treatment for dispersibility and persistence. In this case, the powder pigment is Methicon, Dimethicon, Triethoxycaprylylsilane, Isopropyl Titanium Triisostearate, Magnesium Stearate , Glyceryl Behenate, Aluminum Stearate, DEA-C8-18 Perfluoroalkylethyl Phosphate, or mixtures thereof. . In another embodiment, the powder pigment may be included in 5 to 60% by weight of the total composition. For example, 5 to 55 wt%, 5 to 45 wt%, 5 to 35 wt%, 5 to 25 wt%, 5 to 15 wt%, 10 to 55 wt%, or 15 to 45 wt% . At this time, when the content of the powder pigment is less than the above range, there is a problem that it cannot sufficiently exhibit the effect of a soft finish and covering power, and when it exceeds the above range, it increases the dryness of the skin and makes it difficult to express smooth makeup, as well as formulation stability and usability. There is a problem that can fall.

 The composition may further include a moisturizer. The humectant may include, for example, a polyol selected from the group consisting of glycerin, butylene glycol, propylene glycol, dipropylene glycol, pentylene glycol, hexylene glycol, polyethylene glycol, sorbitol, or any combination thereof. Specifically, the polyol may be included in 0.1 to 5% by weight of the total composition of the composition. For example, 0.1 to 5% by weight, 0.1 to 4% by weight, 0.1 to 2% by weight, 0.1 to 1.5% by weight or 0.1 to 1% by weight may be included. At this time, if the content of the polyol is less than the above range, there is a problem that the moisturizing persistence is lowered, and if it exceeds the above range, it affects the formulation stability and there is a problem that the stickiness and dampness increase and the feeling of use decreases.

The composition according to one embodiment may exhibit a level of hardness that can be used as a solid cosmetic. For example, the hardness may be 30 to 500N, 30 to 400N, 30 to 300N, 30 to 200N, 30 to 100N, 50 to 500N, 50 to 300N, 50 to 150N, or 100 to 200N. At this time, when the hardness of the composition is less than the above range, there is a problem that formulation stability and usability may be deteriorated. If it exceeds the above range, there is a problem that the composition is not taken into puff and is difficult to manufacture.

The composition according to one embodiment may be implemented in a two-dimensional or three-dimensional form using a separate molding mold. Accordingly, one aspect provides a cosmetic composition for dispersing solid foundation molding. The cosmetic composition for molding may be embodied in various forms by, for example, a plate for maintaining a molded state in a three-dimensional mold inside a container, and the composition being molded by a three-dimensional mold. have. Conventionally, after the step of molding the composition to produce a solid foundation having a three-dimensional shape, the bond was used to attach to the dish, and as well as affecting the stability of the composition, it is difficult to maintain the quality of the product by damaging the shape There was a problem. However, the container has a plurality of holes formed on a plate, and not only can the composition be safely protected by filling the composition through the hole, but also the composition can be molded to form various shapes. In addition, the container may have, for example, a shape in which a plurality of holes are formed and the top and bottom are opened in a state in which the plate is assembled to the container body, and may be composed of a mold and an assembly space. The mold may be a silicone mold. At this time, the mold may be assembled in a state in which the up and down direction of the container is reversed, and the composition may be filled up to a certain height inside the mold. After a period of time, when the composition is cured to a solid state, the upside-down container body is turned over so that the upside-down state is the original state, and then the silicone mold over the top of the container body can be removed. have. Therefore, the composition may be protected in a state filled in a cosmetic container in a pact form.

1 is an exploded perspective view of a cosmetic container 100 of a solid foundation having a three-dimensional shape according to an embodiment of the present invention.

Referring to FIG. 1, the cosmetic container 100 may include a body 120, a dish 110, and a lid 130. The liquid foundation composition may be cured while being contained in the dish 110 to become a solid foundation 190. A detailed description of the method for manufacturing the solid foundation 190 having a three-dimensional shape will be described later in detail with reference to FIGS. 3 to 6.

In the dish 110, a three-dimensionally cured solid foundation 190 may be accommodated. The solid foundation 190 may be supported by the dish 110. That is, the upper surface 110-1 of the dish 110 may be in contact with the solid foundation 190, and the lower surface 110-2 of the dish 110 may be in contact with the main body 120 of the cosmetic container 100. Can be. In some embodiments, the lower surface 110-2 of the dish 110 is assembled to the upper surface 120-1 of the main body 120 or adhered to the upper surface 120-1 of the main body 120 using an adhesive. Can be. Although not shown, in order for the plate 110 to be assembled to the main body 120, irregularities may be formed on the bottom surface 110-2 of the plate 110 and the top surface 120-1 or the side surface of the main body 120. have. In some other embodiments, the plate 110 and the body 120 may be assembled by receiving the plate 110 in the body 120 and inserting a ring. For example, the plate 110 may be accommodated in the main body 120, and a ring surrounding the plate 110 may be inserted between the plate 110 and the main body 120.

The upper surface 110-1 of the dish 110 may have the unevenness 119 so that the cured solid foundation 190 does not deviate or move. The irregularities 119 may be, for example, ribs.

The dish 110 may include one or more holes 115. Through at least some of the one or more holes 115, the liquid composition before curing may be filled in the dish 110. A detailed description of the process of filling the foundation composition and the one or more holes 115 will be described later in detail in FIGS. 3 to 6.

The plate 110 may have side walls surrounding the plate 110. The side wall may be formed along the boundary of the plate 110 and in the direction of the top surface 110-1 of the plate 110. The side wall may support the composition or the solid foundation 190 so that the composition in the liquid state filled in the dish 110 has a thickness and is cured into the solid foundation 190.

The plate 110 may have various materials. For example, the plate 110 includes aluminum, PP (Polypropylene), PET (Polyethylene Terephthalate), PETG (Glycol Modified Polyester Terephthalate), ABS (Acrylonitrile-Butadiene-Styrene), PC (Polycarbonate), AS (Acrylonitrile Styrene), Acrylic, and / or PCTA may include at least one of various materials. The material of the dish 110 may be a material commonly used in cosmetic containers.

The lid 130 may be disposed to secure a sufficient space so that the solid foundation 190 having a three-dimensional shape can be accommodated in the cosmetic container 100. The lid 130 may form a sufficient upper and lower space inside the cosmetic container 100 to protect the three-dimensional shape of the solid foundation 190. According to an embodiment, even when the lid 130 is closed, at least a portion of the lid 130 may include a transparent material so that the three-dimensional shape of the solid foundation 190 can be seen from the outside. Alternatively, the lid 130 may be made of an opaque material.

2A-2B show an example of a mold 200 required to produce a solid foundation having a three-dimensional shape according to one embodiment of the present invention. The mold 200 represents a mold and a cast for creating a three-dimensional shape of a solid foundation (eg, solid foundation 190).

2A shows the mold 200 positioned with the three-dimensional shape facing upward. When the mold 200 is positioned with the three-dimensional shape facing upward, the outer surface 200-1 of the mold 200 may face upward.

2B shows the mold 200 positioned with the three-dimensional shape facing downward. When the mold 200 is positioned so that the three-dimensional shape is facing downward, the inner surface 200-2 of the mold 200 can be seen from above. At this time, the outer surface 200-1 of the mold 200 is directed downward. 2B shows a state in which the mold 200 is inverted compared to FIG. 2A.

The inner surface 200-2 of the mold 200 may have various three-dimensional shapes according to the three-dimensional shape of the solid foundation to be made. The mold 200 may have various materials. For example, the mold 200 may include at least one of various materials including silicon, metal, and rubber.

3 is a flowchart for explaining a method of manufacturing a solid foundation having a three-dimensional shape according to an embodiment of the present invention. The processes included in the flowchart may be performed, for example, by a process machine or process system. Alternatively, it may be performed by humans. 3 is explained with reference to FIGS. 4 to 6.

In step S301, the plate 110 and the mold 200 may be assembled such that the first surface of the plate 110 and the inner surface 200-2 of the mold 200 face each other. The first surface of the dish 110 corresponds to the top surface 110-1 of the dish 110, which is in close contact with the solid foundation. That is, the plate 110 and the mold 200 may be assembled such that the upper surface 110-1 of the plate 110 and the inner surface 200-2 of the mold 200 face each other. 4 shows an example of a state in which the dish 110 and the mold 200 are assembled according to an embodiment of the present invention. In a state in which the dish 110 and the mold 200 are assembled, the lower surface 110-2 of the dish 110 and the outer surface 200-1 of the mold 200 are exposed to the outside. Hereinafter, the dish 110 and the mold 200 assembled may be referred to as a dish-mold assembly.

In order for the dish 110 and the mold 200 to be assembled with each other, an area where the dish 110 is assembled on the inner surface 200-2 of the mold 200 corresponds to the area and shape of the dish 110. The inner surface 200-2 of the mold 200 has a shape corresponding to the three-dimensional shape of the solid foundation to be made. The three-dimensional shape may include various shapes of 2D to 3D.

In step S302, through the first hole 501 of the one or more holes 115 of the plate 110, the foundation composition 590 is assembled with the plate 110 and the mold 200 (ie, a plate-mold) Assembly) (see FIG. 5). At this time, the foundation composition 590 is in a liquid state. Therefore, it is possible to fill the liquid foundation composition 590 in a state where the outer surface 200-1 of the mold 200 is positioned to face downward. In other words, the foundation composition 590 may be filled with the lower surface 110-2 of the dish 110 facing upward. 5 is an exploded perspective view conceptually illustrating a process of filling the foundation composition 590 according to an embodiment of the present invention.

The foundation composition 590 may not contain wax. The foundation composition 590 may be in a liquid state at a predetermined temperature or higher (eg, 65 to 70 ° C or higher). The foundation composition 590 may be in a solid state at a constant temperature or less. For example, the foundation composition 590, which is in a liquid state at T1 ° C, may be poured into a dish-mold assembly and cooled in a T2 ° C environment lower than T1 ° C. At T2 ° C., the foundation composition 590 can be cured to a solid state. T1 and T2 may vary depending on the nature of the composition.

The first hole 501 of the one or more holes 115 of the dish 110 may serve as an inlet for filling the liquid composition 590. When filling the composition 590 through the first hole 501, a problem may arise in which the dish 110 is pushed out of the mold 200 due to an increase in the internal pressure of the dish-mold assembly. Therefore, in order to prevent such a problem, the plate 110 may further include a second hole 502 different from the first hole 501. The second hole 502 of the one or more holes 115 of the dish 110 is filled with the foundation composition 590 into the inside of the dish-mold assembly, so that the air inside the dish-mold assembly is blown out. Can serve as an air outlet for However, this is only one embodiment, the plate 110 according to an embodiment of the present invention may include only one hole (eg, the first hole 501), and the composition 590 through the one hole Of course, it can be filled.

The liquid composition 590 may be introduced into the first hole 501 through, for example, a nozzle (not shown). The manufacturing process according to an embodiment of the present invention, the amount of the composition (590) to be introduced into the interior of the dish-mold assembly through the nozzle (eg, volume) is designed to correspond to the volume inside the dish-mold assembly Can be. Thus, the liquid composition 590 can be filled by design so as not to overflow from the inside of the dish-mold assembly. The composition 590 may be filled such that the outer surface of the composition 590 is in close contact with (or touches) the first surface (ie, the upper surface 110-1) of the dish 110.

The first hole 501 serving as an inlet of the composition 590 may be one, or may be a plurality. For example, if there is one first hole 501, the first hole 501 may be positioned at the center of the dish 110 so that the composition is evenly filled inside the dish-mold assembly. Alternatively, the first hole 501 may not be located in the center of the dish 110. For another example, a plurality of first holes 501 may be symmetrically formed relative to the center of the dish 110 so that the composition is evenly filled inside the dish-mold assembly. Alternatively, the plurality of first holes 501 may not be formed symmetrically. As another example, when there are a plurality of first holes, compositions of different colors may be filled through each of the first holes. At this time, different colored compositions may be mixed in the interior of the dish-mold assembly to form a marble.

The second hole 502 serving as an air blowing port may be one or a plurality of holes. For example, when the composition is filled, a plurality of second holes 502 may be symmetrically formed with respect to the center of the dish 110 so that the air inside the dish-mold assembly is blown out evenly. Alternatively, the plurality of second holes 502 may not be formed symmetrically. In addition, the second hole 502 may serve to evenly spread the filled compositions while the air is ejected. Thus, by forming the plurality of second holes 502 evenly in the edge region of the dish 110, the filled compositions can be spread evenly inside the dish-mold assembly.

According to an embodiment, as shown in FIG. 5, the plate 110 includes a plurality of second holes symmetrically distributed in an outer region with respect to the center, including one first hole 501 at the center. It may include a hole 502. However, as described above, the present invention is not limited thereto, and one or more holes may be variously disposed on the plate 110. For example, the first hole 501 and the second hole 502 may not be exclusively separated from each other. In some cases, some of the one or more holes 115 disposed in the dish 110 may serve as an inlet port or may serve as an air outlet port.

In step S303, when the foundation composition 590 is cured into a solid foundation 190, the mold 200 may be removed from the cured solid foundation 190. Specifically, in a state in which the dish-mold assembly is positioned such that the outer surface 200-1 of the mold 200 faces down, the liquid foundation composition 590 may be cured into the solid foundation 190. The process of curing the liquid composition 590 to the solid foundation 190 may be a process of cooling the liquid composition 590. The liquid composition 590 may be cooled at room temperature or room temperature, or may be cooled in a refrigerated or frozen state. For example, conditions for cooling the composition 590 in a liquid state (eg, temperature) may vary depending on the properties (eg, formulation, formula) of the composition 590. In various embodiments, the temperature at which the composition 590 is cooled may be specified.

The foundation composition 590 may be cured to a solid shape while being in close contact with the first surface (ie, the upper surface 110-1) of the dish 110. Thus, when the composition 590 is cured with a solid foundation 190, the solid foundation 190 and the first surface of the dish 110 may be in a state of adhesion to each other. By curing the composition 590 and the first surface of the dish 110 in contact, the cured solid foundation 190 and the first surface of the dish 110 can be naturally attached without a separate adhesive.

When the foundation composition 590 is cured with the solid foundation 190, the mold 200 may be removed from the solid foundation 190 adhered to the dish 110. The method of removing the mold 200 is not limited. For example, the mold 200 may be detached from the solid foundation 190 by pulling the outer surface 200-1 of the mold 200 or by finely deforming at least a part of the mold 200. According to some embodiments, when the mold 200 is made of silicon or rubber, the shape of the mold 200 may be changed flexibly, so that the shape of the mold 200 is finely deformed (or by pulling the mold 200) ) The mold 200 can be detached. According to some other embodiments, when the mold 200 is a metal material, the mold 200 may be removed by splitting the mold 200 into two or more pieces.

While removing the mold 200, the solid foundation 190 may remain attached to the first surface (ie, the upper surface 110-1) of the dish 110. The mold 200 is removed, and the dish 110 and the solid foundation 190 are integrally movable. 6 shows an example of a state in which the dish 110 and the solid foundation 190 are integrated according to an embodiment of the present invention.

In step S304, the second surface of the dish 110 integrated with the solid foundation 190 may be attached to the cosmetic container 100. The second surface of the plate 110 is opposite to the first surface, and corresponds to the lower surface 110-2 of the plate 110. The lower surface 110-2 of the dish 110 integrated with the solid foundation 190 may be attached to the main body 120 of the cosmetic container 100. For example, the lower surface 110-2 of the dish 110 may be assembled to the upper surface 120-1 of the main body 120 or adhered to the upper surface 120-1 of the main body 120 using an adhesive. . In the process of attaching the dish 110 to the cosmetic container 100, the dish 110 can be picked up and moved without having to pick up the contents of the solid foundation 190 directly. Therefore, a problem in which the cosmetic contents may be melted or the shape of the contents may be damaged in a conventional moving process can be solved. In one embodiment of the present invention, using a tool, hand, process machine or the like, the plate 110 is attached to the cosmetic container 100 by supporting and moving the side or bottom surface 110-2 of the plate 110. Can be.

According to one embodiment, in order for the lower surface 110-2 of the plate 110 to adhere to the upper surface 120-1 of the main body 120, the lower surface 110-2 of the plate 110 has a sufficient area. Can be. For example, the lower surface 110-2 of the dish 110 may have a flat surface of a predetermined area or more.

7 shows an example of a dish according to another embodiment of the present invention.

The dish according to various embodiments of the present invention is not limited to the dish 110 and may have various shapes. For example, the plate 710 according to an embodiment of the present invention may have only a skeleton, with the underside pierced. When the dish 710 is used, it may have an advantage that the composition is easily filled evenly when there is no pressure inside when filling the composition, but the adhesive strength may drop when the dish 710 is attached to the cosmetic container 100 Can have

The dish according to various embodiments may not be circular, and may have various shapes such as a square and a polygon.
