Core-shell particle and production method therefor, dye composition, oral composition, liquid oral composition and production method therefor, and method for forming pattern in liquid

Abstract

The present invention aims to provide a colorant composition that contains core-shell particles encapsulating a colorant and that can be used for forming a pattern such as a line in a liquid such as a drink, as well as a liquid oral composition containing the colorant composition and a production method therefor, and a method for forming a pattern in a liquid. The present invention relates to a colorant composition containing a first liquid and core-shell particles, the core-shell particles each including a core and a shell that encapsulates the core, the core containing an oily component and a colorant, the shell containing a cationic polymer, the cationic polymer being edible, the core-shell particles being dispersed in the first liquid.
