Abstract

The present invention relates to a method for producing a multi-capsule, the method including steps of: (a) preparing a coating solution by mixing purified water, titanium dioxide, mica, a hydrophobic polymer, cellulose gum, and sucrose; and (b) drying the coating solution prepared in step (a) while spraying the coating solution through a spray nozzle of a fluid bed dryer after introducing a spherical seed of a colorant component for a cosmetic; or a starch or sucrose spherical seed coated with a functional component into the fluid bed dryer, a multi-capsule produced by the method, and a cosmetic composition containing the multi-capsule as an active component.

Claims

1. A method for producing a multi-capsule, the method comprising steps of:

(a) preparing a coating solution by mixing purified water, titanium dioxide, mica, a hydrophobic polymer, cellulose gum, and sucrose; and

(b) drying the coating solution prepared in step (a) while spraying the coating solution through a spray nozzle of a fluid bed dryer after introducing a spherical seed of a colorant component for a cosmetic;

or a starch or sucrose spherical seed coated with a functional component into the fluid bed dryer.

2. The method of claim 1, wherein the coating solution of step (a) is prepared by mixing 63 to 69 parts by weight of purified water, 23 to 27 parts by weight of titanium dioxide, 4 to 6 parts by weight of mica, 2.5 to 3.5 parts by weight of a hydrophobic polymer, 0.4 to 0.6 part by weight of cellulose gum, and 0.4 to 0.6 part by weight of sucrose based on 100 parts by weight of the coating solution.

3. The method of claim 2, wherein the method of producing the multi-capsule comprises steps of:

(a) preparing a seed of a colorant component by spray-drying a mixture obtained by mixing a colorant component for a cosmetic selected from the group consisting of iron oxide yellow, iron oxide red, iron oxide black, chromium oxide green, and ammonium manganese phosphate with purified water, titanium oxide, cellulose gum, and sucrose;

(b) preparing a coating solution by mixing 63 to 69 parts by weight of purified water, 23 to 27 parts by weight of titanium dioxide, 4 to 6 parts by weight of mica, 2.5 to 3.5 parts by weight of a hydrophobic polymer, 0.4 to 0.6 part by weight of cellulose gum, and 0.4 to 0.6 part by weight of sucrose based on 100 parts by weight of the coating solution; and

(c) drying the coating solution prepared in step (b) while spraying the coating solution through a spray nozzle of a fluid bed dryer after introducing the seed of the colorant component prepared in step (a) into the fluid bed dryer.

4. The method of claim 2, wherein the method of producing the multi-capsule comprises steps of:

(a) producing a core seed by introducing, into a fluid bed dryer, sucrose or a mixture obtained by mixing one or more components selected from the group consisting of corn starch, sucrose, titanium dioxide, and cellulose gum with purified water, and then drying the resulting mixture while spraying the mixture;

(b) preparing a functional component mixture by mixing one or more functional components selected from the group consisting of lycopene, anthocyanin, xanthophyll, chlorophyll, ascorbic acid, and salicylic acid with purified water, corn starch, a hydrophobic polymer, and cellulose gum;

(c) primarily coating the core seed prepared in step (a) by drying the functional mixture prepared in step (b) while spraying the functional mixture through a spray nozzle of a fluid bed dryer after introducing the core seed into the fluid bed dryer;

(d) preparing a secondary coating solution by mixing 63 to 69 parts by weight of purified water, 23 to 27 parts by weight of titanium dioxide, 4 to 6 parts by weight of mica, 2.5 to 3.5 parts by weight of a hydrophobic polymer, 0.4 to 0.6 part by weight of cellulose gum, and 0.4 to 0.6 part by weight of sucrose based on 100 parts by weight of the coating solution;

(e) secondarily coating the primarily coated coating capsule of step (c) by drying the secondary coating solution prepared in step (d) while spraying the secondary coating solution through a spray nozzle of a fluid bed dryer after introducing the primarily coated coating capsule into the fluid bed dryer; and

(f) preparing a tertiary coating solution in which ethanol and cellulose derivatives are mixed, introducing the secondarily coated coating capsule of step (e) into a fluid bed dryer, and then drying the prepared tertiary coating solution while spraying the tertiary coating solution through a spray nozzle of the fluid bed dryer.

5. A multi-capsule produced by the method of claim 1.

6. A cosmetic composition comprising the multi-capsule of claim 5 as an active component.
