Description

Oil-dispersed cosmetic composition and method for manufacturing the same

[0001] The present invention relates to an oil-dispersed cosmetic composition, specifically an oil-dispersed cosmetic composition for lip makeup, and a method for manufacturing the same.

[0002] Generally, cosmetic compositions consisting of oil-dispersed formulations use oil-phase pigments to ensure the stability of the composition. Specifically, it is common to use oil-phase pigments because using water-phase pigments can lead to separation due to poor mixing with oil.

[0003] However, compared to water-based pigments, these oil-based pigments have a relatively very weak degree of skin coloring, which presents a problem in that it is somewhat difficult to satisfy the needs of consumers who desire coloring.

[0004] Accordingly, oil-soluble coloring pigments were introduced as coloring agents usable in oil-dispersed formulations. However, since oil-soluble coloring pigments can only color pink upon contact with water, this also presented a problem in that it was somewhat difficult to satisfy consumers' needs for coloring in various colors.

[0005] To solve these problems, a method of mixing the aqueous phase into the oil phase was introduced, but there were some stability issues, such as formulation separation or sweating in the stick.

[0006] Therefore, there is a need to develop oil-dispersed cosmetic compositions that can be colored with individual colors and have excellent durability.

[0007] The present invention aims to provide an oil-dispersed cosmetic composition capable of being colored with individual colors.

[0008] In addition, the present invention aims to provide an oil-dispersed cosmetic composition with excellent longevity.

[0009] In addition, the present invention aims to provide a method for preparing an oil-dispersed cosmetic composition that can be easily prepared, which is capable of being colored with individual colors and has excellent durability.

[0010] The present invention provides an oil-dispersible cosmetic composition comprising: an oil film-forming agent comprising a silicone-based compound and a glyceride-based compound containing an alkyl group; an oil; and a pigment.

[0011] In addition, the present invention provides a method for preparing an oil-dispersible cosmetic composition, comprising the steps of: mixing an oil film-forming agent and an oil to obtain a first composition; adding a pigment to the first composition to obtain a second composition; and removing impurities from the second composition to obtain an oil-dispersible cosmetic composition, wherein the oil film-forming agent comprises a silicone-based compound containing an alkyl group and a glyceride-based compound.

[0012] The oil-dispersed cosmetic composition according to the present invention has the advantage of being able to be colored into individual colors.

[0013] In addition, the oil-dispersed cosmetic composition according to the present invention has the advantage of excellent longevity.

[0014] In addition, the method for preparing an oil-dispersed cosmetic composition according to the present invention has the advantage of enabling coloring into individual colors even when oil-based pigments are included, and allowing for the easy preparation of an oil-dispersed cosmetic composition with excellent durability through a simple process.

[0015] Figure 1 is an image showing the results of a durability test of an oil-dispersed cosmetic composition according to an example and a comparative example.

[0016] The present invention will be explained in more detail below with reference to examples. However, these examples are intended to illustrate the invention and should not be interpreted as limiting the scope of the invention.

[0017] Oil-dispersed cosmetic composition

[0018] One aspect of the present invention relates to an oil-dispersing cosmetic composition comprising: an oil film-forming agent comprising a silicon-based compound and a glyceride-based compound containing an alkyl group; an oil; and a pigment.

[0019] The oil-dispersed cosmetic composition according to the present invention can be colored into individual colors, thereby satisfying consumer demands, and has the advantage of excellent durability.

[0020] Specifically, the oil-dispersed cosmetic composition according to the present invention has the advantage of being highly useful in various oil-dispersed cosmetic compositions because, by using a silicone-based compound containing an alkyl group and a glyceride-based compound together, it is possible to color the desired color even though it is an oil-dispersed formulation.

[0021]

[0022] Oil film forming agent

[0023] The oil-dispersible cosmetic composition according to the present invention comprises an oil film-forming agent comprising a silicone-based compound containing an alkyl group and a glyceride-based compound.

[0024] The above film-forming agent can perform the role of protecting pigments and active ingredients from being easily wiped away by forming a thin film on the surface of the lips when the above oil-dispersed cosmetic composition is applied to the skin, for example, when applied to the lips.

[0025] Specifically, a silicone-based compound containing an alkyl group was used to improve the coloring and longevity of the oil pigment, and a glyceride oil that can enhance the performance of the said ingredient was used together to enable the oil pigment to adhere well to the skin and to adhere more easily to the skin, such as the lips.

[0026] In addition, it can prevent moisture evaporation from the lip surface to suppress the phenomenon of the lips becoming dry, and can also play a role in improving the gloss and spreadability of the oil-dispersed cosmetic composition.

[0027] In particular, the oil-dispersible cosmetic composition according to the present invention has the advantage of maximizing the effect of forming an oil film that helps oil-phase pigments remain on the skin by combining a silicone-based compound containing an alkyl group and a glyceride-based compound.

[0028] Although I do not wish to be limited by theory, when combining a silicone compound containing an alkyl group and a glyceride compound, the silicone compound containing an alkyl group forms an oil film on the oil pigment so that the oil pigment adheres well to the skin and maintains it, and in addition, the glyceride oil, which is light, absorbs quickly into the skin, and helps moisturize the skin, helps the oil pigment adhere to the lips more easily.

[0029] The silicon-based compound containing the above alkyl group can perform the role of forming an oil film.

[0030] In the present invention, "silicon-based compound containing an alkyl group" may refer to a siloxane polymer having an alkyl group.

[0031] In one embodiment of the present invention, the silicon-based compound containing the alkyl group may comprise one or more selected from the group consisting of alkyl dimethicone-based compounds and esterified alkyl silicon-based compounds.

[0032] When the above alkyl dimethicone compound is included, it is desirable to provide a continuous oil film, thereby maximizing the durability of the color.

[0033] In another embodiment of the present invention, the alkyl dimethicone-based compound may include C20 to C24 alkyl dimethicone.

[0034] In short, the silicon-based compound containing the above alkyl group may be a C20 to C24 alkyl dimethicone.

[0035] When the silicone compound containing the above alkyl group is the C20 to C24 alkyl dimethicone, it is desirable because it provides excellent adhesion and a continuous oil film to the lip surface, thereby maximizing the effect of improving color retention.

[0036] When the above-mentioned esterified alkyl silicone-based compound is included, it is desirable to have excellent oil film formation properties and simultaneously provide spreadability and moisturizing effects.

[0037] In another embodiment of the present invention, the esterified alkyl silicon-based compound may include C16 to C18 alkyl glyceryl dimethicone.

[0038] In another embodiment of the present invention, the esterified alkyl silicon-based compound may include bis-C16-C18 alkylglycerylundecyl dimethicone.

[0039] In short, the silicon-based compound containing the above alkyl group may be bis-C16-C18 alkylglycerylundecyl dimethicone.

[0040] When the silicone compound containing the above alkyl group is bis-C16-C18 alkylglycerylundecyl dimethicone, it can provide a smooth spreadability on the lips and also has the advantage of providing excellent moisturizing effects and natural shine.

[0041] The above glyceride-based compound is an ester formed from glycerol and fatty acids.

[0042] The above glyceride-based compound is lightweight, absorbs quickly into the skin, and helps moisturize the skin, which helps the oil-based pigment adhere more easily to the lips. Therefore, even when only a silicone-based compound containing an alkyl group is included without glyceride oils, pigmentation and longevity are achieved; however, when glyceride oils are also included, the pigmentation is better and the longevity is enhanced.

[0043] In another embodiment of the present invention, the glyceride-based compound may comprise one or more selected from the group consisting of caprylic / capric triglycerides and C10 to C18 triglycerides.

[0044] Specifically, the above glyceride-based compound may be a caprylic / capric triglyceride.

[0045] In the case where the above glyceride-based compound is a caprylic / capric triglyceride, it is desirable to provide the effect of keeping the lips moist by rapidly absorbing it when applied to the skin, specifically the lips, in addition to the effect of the above glyceride-based compound.

[0046] In another embodiment of the present invention, the oil film-forming agent may be included in an amount of 10 to 40 weight%, preferably 15 to 38 weight%, and more preferably 20 to 37 weight%, based on 100 weight% of the total cosmetic composition.

[0047] When the above film-forming agent is included within the above range, it is desirable as it offers excellent compatibility and has the advantage of increasing color longevity by suppressing the phenomenon of the oil film formed after application to the lips sliding off.

[0048] In another embodiment of the present invention, the silicon-based compound containing the alkyl group and the glyceride-based compound may be included in a weight ratio of 1:1 to 1:4, preferably 1:1.5 to 1:3, and more preferably 1:1.7 to 1:2.8.

[0049] When the silicon-based compound containing the alkyl group and the glyceride-based compound are included to satisfy the above range, the mutually complementary effects of the silicon-based compound containing the alkyl group and the glyceride-based compound are maximized, thereby maximizing color retention and providing an oil-dispersed cosmetic composition with excellent coloring effect for individual colors, which is desirable.

[0050]

[0051] oil

[0052] The oil-dispersed cosmetic composition according to the present invention includes oil.

[0053] The above oil may be any oil commonly used in the art, provided that it does not impede the purpose of the present invention.

[0054] For example, the above oil is a hydrocarbon-based oil such as polydecene, hydrogenated polydecene, polybutene, hydrogenated polyisobutene, etc., an ester-based oil such as ethylhexyl hydroxystearate, polyglyceryl-2 triisostearate, polyglyceryl-2 diisostearate, etc.; a synthetic oil such as octyldodecanol, etc.; a fatty acid ester such as dimer dilinoleyl dimer dilinoleate, isostearyl palmitate, etc., a fatty acid alcohol-based oil such as sorbitan isostearate, diisostearyl malate, etc.; Plant-derived oils such as Phytosteryl / Behenyl / Octyldodecyl Lauroyl Glutamate and Diglyceryl Sebacate / Isopalmitate may be used, but are not limited thereto. The above oil may be included in an amount of 30 to 80 weight%, preferably 40 to 70 weight%, and more preferably 45 to 60 weight% based on 100 weight% of the total oil-dispersed cosmetic composition.

[0055] When the above oil is included within the above range, there is an advantage of excellent compatibility among the components included in the oil-dispersed cosmetic composition. In addition, it is desirable to provide an oil-dispersed cosmetic composition that has appropriate flowability for a pleasant user experience, excellent moisture retention on the lips, and excellent gloss.

[0056]

[0057] pigment

[0058] The oil-dispersed cosmetic composition according to the present invention includes a pigment.

[0059] Specifically, the above pigment may be an oil-based pigment.

[0060] The above-mentioned pigment may be one that is commonly used in the industry, provided that it does not impede the purpose of the present invention and is not harmful.

[0061] For example, the above pigments include red pigments such as Iron Oxides (CI 77491), Red 7 Lake (CI 15850), and Carmine (CI 75470); yellow pigments such as Iron Oxides (CI 77492), Yellow 5 Lake (CI 19140), and Yellow 6 Lake (CI 15985); blue pigments such as Iron Oxides (CI 77499), Carbon Black (CI 77266), and Ultramarine Blue (CI 77007); black pigments such as Iron Oxides (CI 77499), Carbon Black (CI 77266), and Ultramarine Blue (CI 77007); and blue pigments such as Blue 1 Lake (CI 42090), Blue 2 Lake (CI 73015), and Indigo Carmine (CI 73015). White pigments such as Titanium Dioxide (CI 77891) and Zinc Oxide (CI 77947) may be used, but are not limited thereto.

[0062] The above pigment may be included in an amount of 0.5 to 15 weight%, preferably 1 to 10 weight%, more preferably 5 to 10 weight%, based on 100 weight% of the total oil-dispersed cosmetic composition, but is not limited thereto.

[0063] However, if the above pigment is included within the above range, it is desirable to provide an oil-dispersed cosmetic composition that exhibits excellent desired color expression and excellent color retention, both during application and coloring, while minimizing the content of the above pigment.

[0064] The oil-dispersible cosmetic composition according to the present invention may further include one or more selected from the group consisting of wax, paste and additive.

[0065]

[0066] wax

[0067] The above wax can form a film when the above oil-dispersed cosmetic composition dries and perform the role of thickening the contents.

[0068] The above wax may be synthetic wax, ethylene / propylene copolymer, vinylpyrrolidone / eicosene copolymer, C10-18 triglycerides, polyethylene, or synthetic wax such as ceresin wax, microcrystalline wax, ozokerite wax; plant-derived oils such as hardened castor oil, hydrogenated jojoba oil, carnauba wax, and rice wax, but are not limited thereto.

[0069] The above wax may be included in an amount of 0.5 to 20 weight%, preferably 3 to 15 weight%, and more preferably 5 to 13 weight% based on 100 weight% of the total oil-dispersed cosmetic composition.

[0070] When the above wax is included within the above range, it is desirable to suppress the phenomenon where the hardness of the oil-dispersed cosmetic composition increases excessively, causing it to dry out or harden.

[0071]

[0072] Paste

[0073] The above paste is a material having both solid and liquid properties and includes not only monomeric compounds but also low molecular weight compounds and high molecular weight polymers.

[0074] The above paste may be included to control the viscosity of the above oil-dispersed cosmetic composition.

[0075] The above paste is, for example, Dipentaerythrityl Pentaisostearate, Phytosteryl / Isostearyl / Cetyl / Stearyl / Behenyl Dimer Dilinoleate

[0076] It may be Phytosteryl / Behenyl / Octyldodecyl Lauroyl Glutamate, Stearalkonium Hectorite, etc., but is not limited thereto.

[0077] The above paste may be included in an amount of 3 to 25 weight%, preferably 5 to 20 weight%, and more preferably 10 to 20 weight%, based on 100 weight% of the total oil-dispersed cosmetic composition.

[0078] When the above paste is included within the above range, the oil-dispersed cosmetic composition has an appropriate viscosity and can exhibit an excellent user experience, which is desirable.

[0079]

[0080] additives

[0081] The oil-dispersible cosmetic composition according to the present invention may further include additives commonly used in the art, provided that they do not impede the purpose of the present invention.

[0082] For example, the above additive may further include one or more conventional cosmetic ingredients selected from the group consisting of additives such as powder, gel, adenosine or oil-soluble licorice extract, fragrance, filler, preservative, antiseptic, neutralizing agent, UV blocker, sweetener, vitamin, free radical scavenger, and metal ion chelating agent.

[0083] Specifically, the above additive may include tocopherol, synthetic fluorphlogopite, propylene carbonate, etc.

[0084] The above additive may be appropriately added within a range that does not impede the purpose of the oil-dispersed cosmetic composition according to the present invention. For example, the above additive may be included in an amount of 10% by weight or less, preferably 5% by weight or less, and more preferably 0.01 to 3% by weight, based on 100% by weight of the total oil-dispersed cosmetic composition.

[0085] In another embodiment of the present invention, the oil-dispersed cosmetic composition may be for lip makeup.

[0086] The oil-dispersed cosmetic composition according to the present invention uses a silicone-based compound containing an alkyl group, specifically alkyl dimethicone, together with a glyceride-based compound capable of enhancing its performance. This provides the advantage that, despite having an oil-dispersed formulation, it can be colored into individual colors when using an oil-phase pigment. Therefore, it is expected to be highly useful as it can be applied to a wide range of oil-dispersed cosmetic product lines.

[0087] In addition, since it allows for individual color coloring and offers excellent durability, it is expected to be highly preferred by consumers and thus see high demand.

[0088]

[0090] Another aspect of the present invention relates to a method for preparing an oil-dispersible cosmetic composition, comprising the steps of: mixing an oil film-forming agent and an oil to obtain a first composition; adding a pigment to the first composition to obtain a second composition; and removing impurities from the second composition to obtain an oil-dispersible cosmetic composition, wherein the oil film-forming agent comprises a silicone-based compound containing an alkyl group and a glyceride-based compound.

[0091] The oil-dispersed cosmetic composition according to the present invention has the advantage of being able to be colored with individual colors and easily manufactured as an oil-dispersed cosmetic composition with excellent durability.

[0092] The above-mentioned oil film forming agent, oil, pigment, silicone-based compound containing an alkyl group, and glyceride-based compound may be applied as described above.

[0093]

[0094] Step of obtaining the first composition

[0095] A method for preparing an oil-dispersed cosmetic composition according to the invention comprises the step of mixing an oil film-forming agent and an oil to obtain a first composition.

[0096] In the step of obtaining the first composition, wax, paste, and additives may be added together with the oil film forming agent, but are not limited thereto.

[0097] In another embodiment of the present invention, the step of obtaining the first composition may be performed at a temperature of 75 to 90°C, preferably 80 to 90°C, and more preferably 85 to 90°C.

[0098] When the step of obtaining the first composition is performed within the above temperature range, it is desirable that the oil film forming agent, wax, paste, and oil can be uniformly melted and mixed while minimizing energy.

[0099] The step of obtaining the first composition can be performed at 1,500 to 2,500 RPM, preferably 1,800 to 2,500 RPM, more preferably 2,000 to 2,500 RPM, for 3 to 30 minutes, preferably 5 to 25 minutes, more preferably 10 to 20 minutes.

[0100] When the step of obtaining the first composition is performed within the above RPM and time range, it is desirable to obtain a uniform second composition by ensuring sufficient melt mixing while minimizing the mixing time.

[0101] The step of obtaining the first composition above can be performed using a homogenizer, but is not limited thereto, and can be performed using a mixer commonly used in the industry.

[0102]

[0103] Step of obtaining a second composition

[0104] A method for preparing an oil-dispersed cosmetic composition according to the present invention comprises the step of adding a pigment to the aforementioned first composition to obtain a second composition.

[0105] In the step of obtaining the second composition above, additives such as powder may be added together.

[0106] Specifically, the method for preparing an oil-dispersed cosmetic composition according to the present invention uses a two-step method of first obtaining a first composition and then adding and dispersing a pigment, thereby enabling the production of an oil-dispersed cosmetic composition with excellent formulation stability and uniformly dispersed pigment.

[0107] The step of obtaining the second composition above can be performed at a temperature of 75 to 90°C, preferably 80 to 90°C, and more preferably 85 to 90°C.

[0108] It is preferable that the step of obtaining the second composition is performed within the above temperature range, so that the second composition in which the pigment and powder are uniformly dispersed can be obtained.

[0109] The step of obtaining the second composition above can be performed at 1,500 to 2,500 RPM, preferably 1,800 to 2,500 RPM, more preferably 2,000 to 2,500 RPM for 3 to 25 minutes, preferably 5 to 20 minutes, more preferably 10 to 18 minutes.

[0110] When the step of obtaining the second composition is performed within the above RPM and time range, it is desirable to obtain a uniform second composition by ensuring sufficient dispersion of the pigment while minimizing the mixing time.

[0111] The step of obtaining the second composition above can be performed using a homogenizer, but is not limited thereto, and can be performed using a mixer commonly used in the industry.

[0112]

[0113] Bubble removal step

[0114] In another embodiment of the present invention, the method may further include the step of obtaining the second composition; and the step of removing bubbles from the second composition.

[0115] If the method further includes a step of removing bubbles from the second composition, in other words, a degassing step, it is desirable because the texture of the finally produced oil-dispersed cosmetic composition becomes smoother and adhesion is improved when applied to the skin, specifically the lips. Furthermore, since it can suppress discoloration or quality degradation caused by bubbles, thereby contributing to enhancing product stability as well as visual perfection, it is desirable to further include the degassing step.

[0116] The above degassing step may be performed using a vacuum desiccator, a vacuum degassing device, etc., but is not limited thereto.

[0117]

[0118] Impurity removal step

[0119] A method for preparing an oil-dispersed cosmetic composition according to the present invention comprises the step of removing impurities from the aforementioned second composition to obtain an oil-dispersed cosmetic composition.

[0120] The above impurities can be removed by filtration.

[0121] By removing impurities from the second composition above, it is desirable to obtain an oil-dispersed cosmetic composition that not only offers excellent usability when applied to the skin, specifically the lips, but also has high long-term stability.

[0122]

[0123] Plastic surgery stage

[0124] In another embodiment of the present invention, the step of forming the oil-dispersible cosmetic composition may be further included.

[0125] Specifically, the above oil-dispersible cosmetic composition may further include, but is not limited to, the step of pouring into a mold and cooling to obtain the desired form.

[0126] If necessary, the method may further include a step of heating the above oil-dispersible cosmetic composition to a temperature of 75 to 90°C to pour it into the mold, but is not limited thereto.

[0127] The above cooling may be performed at room temperature or at a temperature of -20 to 10°C for 5 to 30 minutes, but is not limited thereto.

[0128] However, if the above cooling is performed below the above temperature range, cracks may occur in the final product, so it is preferable to perform it within the above range.

[0129]

[0130] Hereinafter, preferred embodiments are described to explain the present invention in more detail. However, the following embodiments are described solely for the purpose of illustrating the present invention and are not intended to limit the present invention.

[0131]

[0132] Preparation of Examples and Comparative Examples 1

[0133] (1) Example 1

[0134] After weighing wax, oil, and paste raw materials into a beaker to satisfy the composition according to Table 1 below, the first composition was obtained by uniformly melting and mixing using a homogenizer at 2,500 RPM for 20 minutes while maintaining a heating state of 85 to 90°C for mixing.

[0135] After that, powder and pigment were added to the first composition and dispersed to satisfy the composition according to Table 1 below. Specifically, the second composition was obtained by dispersing at 2,500 RPM for 10 minutes using a homomixer while maintaining a heating state of 85 to 90°C.

[0136] After completing a degassing process to remove bubbles in the second composition, the lip makeup cosmetic composition (oil-dispersed cosmetic composition) was prepared by filtering to remove impurities.

[0137] Subsequently, the manufactured oil-dispersible cosmetic composition was subjected to molding and cooling processes to produce a final product for lip makeup.

[0138]

[0139] (2) Example 2

[0140] The composition was prepared in the same manner as in Example 1, but in the step of preparing the first composition, it was prepared by including 2.1% by weight of Caprylic / Capric Triglyceride, which is a glyceride-based compound.

[0141]

[0142] (3) Example 3

[0143] A lip makeup cosmetic composition was prepared in the same manner as in Example 1, but in the step of preparing the first composition, bis C16-18 alkyl glyceryl undecyl dimethicone was included instead of C20-24 alkyl dimethicone, which is an alkyl dimethicone compound.

[0144]

[0145] (4) Comparative example

[0146] A lip makeup cosmetic composition was prepared in the same manner as in Example 1, but the C20-24 alkyl dimethicone, which is an alkyl dimethicone compound, was excluded during the step of preparing the first composition.

[0149]

[0150] Experimental Example 1: Confirmation of Color Durability 1

[0151] The same amount of the product prepared according to the examples and comparative examples was applied to the inner arm (inner forearm) of five panelists, and then wiped off with a tissue after 5 minutes, and the results are shown in Figure 1 and Table 2.

[0152] Referring to Fig. 1, it can be seen that the color remains on the inside of the arm in the same color as the color applied in the order of Example 1, Example 2, and Comparative Example.

[0153] The scores indicating coloring intensity from 0 to 5 by the five panelists mentioned above are as follows. (0 points represent low coloring power, 5 points represent high coloring power)

[0154]

[0155] Panel Example 1 Example 2 Comparative Example 1 5 20 25 20 35 31 45 30 55 20 Average 52.40.2

[0156]

[0157] That is, compared to the case containing only one type of alkyl dimethicone compound, it can be seen that the coloring effect is enhanced in the case of Examples 1 and 2, in which a glyceride-based compound is used together.

[0158] Through this, it was confirmed that silicone-based compounds containing alkyl groups form an oil film on the oil pigment to help the oil pigment adhere well to the skin and maintain it, and additionally, glyceride-type oils that are lightweight, quickly absorbed into the skin, and help moisturize the skin help the oil pigment adhere to the lips more easily.

[0159] Therefore, it was confirmed that even when only silicone-based compounds containing alkyl groups are included without glyceride oils, the color is colored and lasts longer, but when glyceride oils are also included, the color is better and lasts longer.

[0160]

[0161] Manufacturing of test products 1 to 5

[0162] Test products 1 to 5 were prepared in the same manner as in Example 1, but with only the color of the pigment changed.

[0163]

[0164] Experimental Example 2: Confirmation of Color Durability 2

[0165] The same amount of the product prepared according to test products 1 to 5 prepared above was applied to the inner side of the arm (inner forearm) of one panelist, and then wiped off with a tissue after 5 minutes, and the results are shown in FIG. 2.

[0166] Through these results, it was confirmed that, similar to the results for Examples 1 and 2, a silicone compound containing an alkyl group forms an oil film on the oil pigment to help the oil pigment adhere well to the skin and maintain it, and furthermore, a glyceride oil that is lightweight, absorbs quickly into the skin, and helps moisturize the skin helps the oil pigment adhere to the lips more easily.

[0167]

[0168] Specifically, given that conventional glossy oil-dispersed formulations generally do not retain color well and thus have poor durability, the oil-dispersed cosmetic composition according to the embodiment of the present invention is capable of coloring to individual colors and exhibits excellent durability, and thus high consumer demand is expected.

[0169]

[0170] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without altering its technical concept or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
