Method for producing composition containing hardly water-soluble aromatic compound

Abstract

To provide a new method for producing a composition containing a hardly water-soluble aromatic compound, the composition having outstanding hardly water-soluble aromatic compound. A method for producing a composition containing a hardly water-soluble aromatic compound, comprising: Step (1) of obtaining a hardly water-soluble aromatic compound solution Step (1) comprising Step (1-1) of preparing a material for heating comprising (A) a hardly water-soluble aromatic compound, (B) a polyol, and (C) an aqueous medium, and Step (1-2) of obtaining a heated solution containing a hardly water-soluble aromatic compound by heating the material for heating at normal pressure at a temperature of less than 100° C.; and Step (2) of obtaining a hardly water-soluble aromatic compound solution 2 by adding water to the hardly water-soluble aromatic compound solution 1 such that the hardly water-soluble aromatic compound solution 2 has a concentration of the (A) hardly water-soluble aromatic compound above a saturation solubility at 25° C., wherein, in Step (1), a content of a surfactant in the material for heating is 0.1 mass % or less and a content of the (A) hardly water-soluble aromatic compound in the material for heating is below a saturation solubility of the (A) hardly water-soluble aromatic compound in a solvent having the same composition at 25° C.
