Abstract
Methods for producing a composition containing a hardly water-soluble aromatic compound are described which involve Step (1), including Step (1-1) for preparing a material comprising: (A) a hardly water-soluble aromatic compound, (B) a polyol, and (C) an aqueous medium, where 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. The obtained solution is then heated in Step (1-2) at normal pressure at a temperature of less than 100° C., to obtain a hardly water-soluble aromatic compound solution 1. Step (2) includes adding water to the hardly water-soluble aromatic compound solution 1 such that the resulting 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.
