The present invention provides: a dispersion composition including a poorly water-soluble polyphenol compound, an emulsifier including a sucrose fatty acid ester, and a water-soluble polymer, in which a content of a polyglycerin fatty acid ester in the composition is 0, or 0.1 or fewer times a total mass of the sucrose fatty acid ester in the composition, and a particle size of the dispersed particles including the poorly water-soluble polyphenol is 200 nm or smaller; and a method for manufacturing the dispersion composition, the method including an oil phase preparation process in which an oil phase is prepared by dissolving one or more oil phase components including the poorly water-soluble polyphenol in a good solvent for the poorly water-soluble polyphenol compound, and a mixing process in which the obtained oil phase and a phase of a poor solvent for the poorly water-soluble polyphenol compound are mixed to obtain the dispersion composition which includes the poorly water-soluble polyphenol compound and includes dispersed particles having an average volume particle size of 200 nm or smaller. |
