It is an object of the present invention to provide a method for producing fine particles containing lipids or fatty acids or derivatives thereof surface-modified with a water-soluble substance by a simpler method, and in a liquid containing a polar organic solvent, lipids Alternatively, the step of allowing the fine particles containing a fatty acid or a derivative thereof to exist in a dispersed state, and causing the surface modifier comprising a lipid derivative, a fatty acid derivative or an aliphatic hydrocarbon derivative of a water-soluble substance to exist in a dissolved or dispersed state. A method for producing the fine particles whose surface is modified with a functional substance is provided. |
