An aliphatic polyester resin composition, useful for producing molded articles without causing deformation at the mold release time, has a non-copolymerized mixture of an aliphatic polyester resin including one or more polylactic acid resins and a crystallization nucleating agent including one or more metal salts of an aromatic sulfonate of Formula 1: 

Aliphatic polyester resin compositions, molded articles of aliphatic polyester resin and method of producing same

Organosilicone fine particles of size in the range of 0.1-20 &#x3bc;m, each having 20 or more faces with indefinite shapes and a network of convex parts that surround these faces with indefinite shapes on its surface, and being spherical as a whole respond to highly advanced requirements of recent years including improvements in optical characteristics of resin compounds, usability and feeling of cosmetics and maintainability of fluidity of development toners. The invention further provides methods of producing such organosilicone fine particles.

Organosilicone fine particles, having specific surface characteristics method of producing same, and cosmetics, resin compositions and development toners containing same
