Description

CROSS REFERENCE TO RELATED APPLICATIONS The present application is a national phase entry under 35 U.S.C. § 371 of International Application No. PCT/KR2019/007516, filed Jun. 21, 2019 which designates the United States of America, which claims priority to KR Application No. 10-2019-0028912, filed Mar. 13, 2019, the entire disclosures of each of these applications are hereby incorporated by reference in their entireties and for all purposes. TECHNICAL FIELD The present invention relates to a capsule coloration cosmetic composition in which the color of capsules is changed by mixing two formulations in use. BACKGROUND ART Recently, in cosmetic products, for the purpose of enhancing aesthetic effects, a method of differentiating the appearance by using colored capsules has been used. However, there was a limit to implementing a capsule composition that is changed in color when applied to a formulation, and until now, by including a colorant inside capsules, only a cosmetic composition that changes the color of the capsules only after breaking the capsules is disclosed. Meanwhile, with the development of dermatology, as gradually shifting to emphasizing the effects on the skin such as skin whitening, anti-aging, and alleviating acne. As the trend is gradually shifted toward emphasizing the effects on the skin, such as skin whitening, anti-aging, and acne relief, the concept of functional cosmetics (cosmeceuticals) emerged as an extension of the concept of cosmetics. However, most of the aforementioned functional ingredients are chemically unstable and there are many substances that are liable to deteriorate by moisture, light, heat, oxygen, etc. Thus, in order to apply the functional ingredients to cosmetics, there is a need for a technology for stabilizing the functional ingredients so as to maintain the original activities thereof without being altered in the manufacturing and distribution process. Accordingly, it is necessary to develop a cosmetic composition that can give an aesthetic effect while enhancing the long-term stability of functional ingredients. PRIOR ART DOCUMENT Patent Literature: KR 10-0347665 B1 DESCRIPTION OF EMBODIMENTS Technical Problem It is an object of the present invention to provide a capsule coloration cosmetic composition that can give an aesthetic feeling by changing the color of capsules while having high long-term stability. Solution to Problem To achieve the object of the present invention, the present invention provides a capsule coloration cosmetic composition comprising: a first formulation comprising capsules; and a second formulation comprising a colored oil-soluble ingredient, wherein the outer membranes of the capsules comprise: a mixed gum comprising acacia gum; and at least one of gelatin and agar, and an oil-based emollient is included inside the capsules. According to an embodiment of the present invention, the first formulation and the second formulation are included in a weight ratio of 1:0.01 to 1:0.3. According to an embodiment of the present invention, the capsules are included in an amount of 0.01 to 50 wt %, based on the total weight of the composition of the first formulation. According to an embodiment of the present invention, the first formulation contains water in an amount of 40 to 90 wt %. According to an embodiment of the present invention, the mixed gum is included in an amount of 1 to 10 wt %, based on the total weight of the composition of the capsule. According to an embodiment of the present invention, in the mixed gum, the acacia gum and the other gums are mixed in a weight ratio of 1:0.01 to 1:1. According to an embodiment of the present invention, the oil-based emollient is included in an amount of 10 to 90 wt %, based on the total weight of the composition of the capsules. According to an embodiment of the present invention, in the capsule composition, water is included in an amount of less than 10 wt %, based on the total weight of the composition of the capsules. According to an embodiment of the present invention, the first formulation further includes a polyol, and the capsules and the polyol are mixed in a weight ratio of 1:1 to 1:3. According to an embodiment of the present invention, the oil-soluble ingredient is included in an amount of 0.001 to 5.0 wt %, based on the total weight of the composition of the second formulation. According to an embodiment of the present invention, water is not included in the second formulation. Advantageous Effects of Disclosure In the capsule coloration cosmetic composition according to the present invention, when a user mixes a first formulation comprising capsules and a second formulation comprising an oil-soluble ingredient immediately before use, the oil-soluble ingredient is absorbed into the capsules and the color of the capsules is changed, and thus the user can directly visually identify that the oil-soluble ingredient enters the capsules, thereby increasing the reliability of the cosmetic compo
