## Abstract

The present invention relates to a method of manufacturing a water-solubilized solution of mastic gum using a novel solvent system. The water-solubilized solution contains no organic solvent such as ethanol. With the new solvent system, a water-solubilized solution of mastic gum can be prepared with no organic solvents such as ethanol, but with a high amount of mastic gum dissolved therein.

## Claims

### Claim 1

A method of manufacturing a water-solubilized solution of mastic gum, comprising:
dissolving mastic gum in ethanol to prepare a first solution;
mixing polyol and purified water to prepare a second solution;
mixing the first solution and the second solution to prepare a third solution;
cooling down the third solution and filtering the third solution to remove insoluble polymer resin; and
removing alcohol from the filtered third solution.

### Claim 2 (depends on 1)

The method of claim 1, wherein the polyol comprises glycerin.

### Claim 3 (depends on 1)

The method of claim 1, further comprising adding a pH adjuster into the second solution.

### Claim 4 (depends on 3)

The method of claim 3, wherein the pH adjuster comprises L-ascorbic acid.

### Claim 5 (depends on 4)

The method of claim 4, wherein a content of the L-ascorbic acid is 1.5 wt % to 3.0 wt %, based on 100 wt % of the third solution.
