## Abstract

The present invention relates to a makeup cosmetic composition containing capsules containing pigments in an inner layer thereof and, more specifically, to a makeup cosmetic composition, which contains a pigment in an inner layer and blocks a pigment from an external environment, thereby preventing pigment discoloration caused by the external environment, and contains capsules readily broken so as to enable color to show when applied to the skin, thereby showing color when applied to the skin even though the color of a formulation is nearly colorless and having an excellent skin coloring ability.

## Claims

### Claim 1

A makeup cosmetic composition comprising a pigment capsule,
wherein the capsule has an inner layer in which silica, a pigment, and a titanium dioxide pigment are dispersed, and an exterior covered with a polymer binder having a glass transition temperature of 130° C. or higher,
wherein a C3-C9 trivalent carboxylic acid is contained in the inner layer of the makeup pigment capsule; and
wherein the polymer binder is an acrylate copolymer the makeup cosmetic composition further includes one or more substance selected from the group consisting of polyhydroxy stearate, dipentaerythrityl tetrabehenate/polyhydroxy stearate, dipentaerythrityl tri-polyhydroxystearate, ethylhexyl polyhydroxy stearate, iso-octyl polyhydroxystearate, and pentaerythrityl behenate/polyhydroxystearate, and a content of the one or more substance is 3 to 40% by weight based on the total weight of the makeup cosmetic composition.

### Claim 2 (depends on 1)

The makeup cosmetic composition of claim 1, wherein a content of the pigment capsule is 0.01 to 30% by weight based on the total weight of the makeup cosmetic composition.
