Abstract

Provided are: a particulate composition which exhibits high water dispersibility regardless of the kind of solid particles; and a method for producing this particulate composition. Also provided are: a liquid composition; a surface modifying agent; and a method for improving water dispersibility. The present invention additionally provides: a particulate composition which has dispersibility in an oil-based material; and a method for producing this particulate composition. A particulate composition according to the present invention contains solid particles and an amphiphilic substance that is present on the surfaces of the solid particles; and the amphiphilic substance has an ability of forming vesicles in water. A method for producing a particulate composition according to the present invention comprises: a step for preparing a mixture of solid particles and a solvent in which amphiphilic substance that has an ability of forming vesicles in water is dissolved; and a step for removing the solvent in the mixture.
