<p><P>PROBLEM TO BE SOLVED: To provide a method for producing an organic crystal grain by which the fine organic crystal grain having excellent slipperiness, touch feeling or the like is efficiently produced over wide organic compounds substantially without requiring an organic solvent. <P>SOLUTION: The method for producing the organic crystal grain comprises (1) a step for packing a low-molecular weight crystalline organic compound having a polar group in a pressure-resistant container, (2) a step for melting the organic compound packed at the step (1) by pouring a fluid into the pressure-resistant container, and achieving a subcritical or supercritical condition of the fluid, and (3) a step for forming the organic crystal grain by cooling and/or reducing the pressure in the pressure-resistant container to solidify the organic compound melted at the step (2). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
