## Abstract

A sugar alcohol microcapsule obtained by mixing particles that include molten sugar alcohol and are dispersed in an oil phase with a material that reacts with the particles, and encapsulating the sugar alcohol.

## Claims

### Claim 1

A production method for a sugar alcohol microcapsule, comprising: obtaining a sugar alcohol microcapsule by mixing particles that include molten sugar alcohol and are dispersed in an oil phase with a material that reacts with the particles, and encapsulating the sugar alcohol.

### Claim 2 (depends on 1)

The production method according to claim 1, wherein an amount of moisture included in the microcapsule is less than 1% by mass with respect to a total of the sugar alcohol microcapsule.

### Claim 3 (depends on 1)

The production method according to claim 1, wherein the material that reacts with the particles is at least one selected from the group consisting of a cyanoacrylate compound, a cyanate compound, an isocyanate compound, and a carboxylic halide.

### Claim 4 (depends on 1)

The production method according to claim 1, wherein the particles further include at least one selected from the group consisting of an amine compound and a water-soluble epoxy compound.

### Claim 5 (depends on 1)

The production method according to claim 1, wherein an average particle diameter of the sugar alcohol microcapsule is 100 μm or less.

### Claim 6 (depends on 1)

The production method according to claim 1, wherein the particles are dispersed in the oil phase using an ultrasonic homogenizer.
