[0051] Hereinafter, the present invention will be described in detail with reference to Preparation Examples and Examples. However, the following Preparation Examples and Examples are only for exemplifying the present invention, and the content of the present invention is not limited by the following Preparation Examples and Examples.

Preparation Example 1: Preparation of Coating Solution

[0052] A method for preparing a coating solution for primary coating a colorant component or secondary coating a functional component for a cosmetic is as follows, and the solid content and viscosity thereof are shown in the following Table 1.

[0053] A coating solution was prepared by mixing 66 parts by weight of purified water, 25 parts by weight of titanium dioxide, 5 parts by weight of mica, 3 parts by weight of a hydrophobic polymer, 0.5 part by weight of cellulose gum, and 0.5 part by weight of sucrose based on 100 parts by weight of the coating solution.

Blending Ratio and Characteristics of Coating Solution

Preparation Example 2: Production of Colorant Double Capsule for Cosmetic

[0054] A seed in the form of a bead was produced by introducing, into a spray dryer, a mixed solution obtained by mixing a colorant component for a cosmetic (iron oxide yellow, iron oxide red, iron oxide black, chromium oxide green, and ammonium manganese phosphate) with purified water, titanium dioxide, cellulose gum, and sucrose at the blending ratio in the following Table 2. In this case, as the spray drying conditions, the temperature of the inlet hot air was 190 C., the internal temperature of the dryer chamber was 100 C., the speed of the sprayer was 8,000 rpm, and the viscosity of the supplied solution was 500 to 700 cps.

[0055] The produced colorant component seed is as shown in FIG. 4, had a particle size of 100 to 200 m, and exhibited a spherical bead shape when the shape was enlarged (FIG. 5). If the shape is irregular instead of the bead shape, there is a problem in that a finally desired capsule may not be manufactured because particles stick to each other during the primary capsule coating in a fluid bed dryer.

[0056] Composition and Characteristics of Mixture for Producing Colorant Component Seed

[0057] A mixture for producing a colorant component seed was produced by introducing the produced colorant seed into a fluid bed dryer and supplying the coating solution of Preparation Example 1 to dry the coating solution while spraying the coating solution onto the surface of the seed by a fluid bed bottom spray method. In this case, as the working conditions, the temperature of the inlet hot air was 90 C., the internal temperature of the product chamber was 50 to 55 C., and the viscosity of the supplied solution was 140 to 160 cps.

[0058] The produced final colorant capsule is as shown in FIG. 6, had a particle size of 90 to 300 m, and exhibited a spherical bead shape when the shape was enlarged (FIG. 7). If the shape is irregular instead of the bead shape, there is a problem in that the capsule is easily broken in the formulation when applied to a cosmetic, and the internal colorant is easily released to the outside.

Preparation Example 3: Production of Functional Multi-Capsule for Cosmetic

[0059] (1) Production of Core Seed

[0060] A core seed in the form of a bead was produced by a tangential spray method by introducing the solution or powder prepared at the blending ratio in the following Table 3 into a fluid bed dryer. In this case, as the working conditions, the temperature of the inlet hot air was 80 C., the internal temperature of the dryer chamber was 55 C., and the viscosity of the supplied solution was 100 to 150 cps.

[0061] The produced core seed is as shown in FIG. 8, had a particle size of 300 to 800 jam, and was used after sorting according to the size. The shape of the particle exhibited a bead shape when observed by enlarging the particle. If the shape is irregular instead of the bead shape, there is a problem in that a finally desired capsule may not be manufactured because particles stick to each other during the primary capsule coating in a fluid bed dryer.

[0062] The produced core seeds were classified into uniform sizes by sieving and applied to the next process, and finally used selectively according to the size of the multi-capsule.

[0067] (3) Primary Coating Treatment

[0068] A primary coating capsule was produced by introducing the produced core seed into a fluid bed dryer and supplying the functional component primary coating solution to dry a primary coating solution while spraying the primary coating solution onto the surface of the core seed powder by a fluid bed bottom spray method. In this case, as the working conditions, the temperature of the inlet hot air was 90 C., the internal temperature of the product chamber was 50 to 55 C., and the viscosity of the supplied solution was 90 to 100 cps.

[0069] (4) Secondary Coating Treatment

[0070] A secondary coating capsule was produced by supplying the coating solution prepared by the method in Preparation Example 1 to the primarily coated capsule to dry the coating solution while spraying the coating solution onto the surface of the primarily coated capsule by a fluid bed bottom spray method. In this case, as the working conditions, the temperature of the inlet hot air was 90 C., the internal temperature of the product chamber was 50 to 55 C., and the viscosity of the supplied solution was 140 to 160 cps.

[0071] (5) Preparation of Tertiary Coating Solution

[0072] A tertiary coating solution was prepared at the blending ratio in the following Table 5.

[0074] (6) Tertiary Coating Treatment

[0075] A thirdly coated multi-capsule was produced by supplying the tertiary coating solution to the secondary coating capsule to dry the tertiary coating solution while spraying the tertiary coating solution onto the surface of the secondarily coated capsule by a fluid bed bottom spray method. In this case, as the working conditions, the temperature of the inlet hot air was 40 C., the internal temperature of the product chamber was 30 C., and the viscosity of the supplied solution was 80 to 100 cps.

[0076] The produced multi-capsule may be produced in various sizes of 300 to 1,500 m and may be produced as a capsule having various functions according to the selection of the internal functional component, and the appearance color may be also be produced as various colors desired by consumers.

Example 1: Comparison of Residual Rates of Functional Multi-Capsules for Cosmetic

[0077] The residual rates of the functional components were compared while the cosmetic functional multi-capsule in Preparation Example 3 was stored at 35 C. As a result of storing ascorbic acid which was not encapsulated and the ascorbic acid functional multi-capsule produced by the method in Preparation Example 3 at 35 C. for 16 weeks, it could be confirmed that the multi-encapsulated ascorbic acid multi-capsule exhibited a high ascorbic acid residual rate of 96.1% even when stored for 16 weeks, but ascorbic acid which was not encapsulated exhibited a low residual rate of 70.5% after 16 weeks (Table 6 and FIG. 11).

[0079] Further, as a result of also storing the respective multi-capsules of anthocyanin, lycopene, xanthophyll, and chlorophyll produced by the method in Preparation Example 3 at 35 C. for 16 weeks, all the multi-capsules exhibited a residual rate of 80% or more even after 16 weeks, but anthocyanin which was not encapsulated (Comparative Example) exhibited a low residual rate of 69.5% after 16 weeks (Table 7 and FIG. 12).

Example 2: Comparison of Functional Component Residual Rates of Cosmetic Functional Multi-Capsules According to Blending Ratio of Coating Solution

[0080] Cosmetic functional multi-capsules were produced by the method in Preparation Example 3, and the functional component residual rates were analyzed from the cosmetic functional multi-capsules coated with coating solutions prepared by varying the blending ratio of the coating solution in Preparation Example 1 used during the secondary coating (Table 8).

[0082] As a result, it could be confirmed that during the production of the cosmetic functional multi-capsule, the production of functional multi-capsules of ascorbic acid and anthocyanin using a coating solution mixed at a blending ratio in Preparation Example 1 in the secondary coating step had a better effect of preserving the functional component than the production of the multi-capsules using the coating solutions in Comparative Examples 3 and 4 (Table 9).

[0083] A cosmetic including 10% of the ascorbic acid multi-capsule produced by the method in Preparation Example 3 and an ascorbic acid multi-capsule were produced by the method in Preparation Example 3, and cosmetics including 10% of ascorbic acid multi-capsules coated with the coating solution prepared by varying the blending ratio (Table 8) of the coating solution in Preparation Example 1 used during the secondary coating were applied to the faces of total 30 adult women consisting of 10 adult women (35.4 years old on average) per treatment group twice a day for a week, and the feeling of use (spreadability, adhesiveness, residual feeling, and skin improvement effect) was evaluated by a 10-point scale method (0 point to 2 points: very poor, 2 points to 4 points: poor, 4 points to 6 points: fair, 6 points to 8 points: good, and 8 points to 10 points: very good). The residual feeling score was higher when there was less residual feeling.

[0084] Evaluation of Feeling of Use of Functional Component Multi-Capsules

[0085] As a result, as can be seen from Table 10, it could be seen that during the production of the multi-capsule, the production of a capsule by performing secondary coating with the coating solution in Preparation Example 1 had the best spreadability, adhesiveness, residual feeling, and skin improvement effect, and the overall average score was also 8.2 points, which indicates an excellent feeling of use.
