Beschreibung
Zusammenfassung:	A composite cured silicone powder comprising:(A) a cured silicone powder having an average particle size of 0.1 to 500[mu]m, (B) an inorganic fine powder coated on the surface of said cured silicone powder and (C) a monohydric or polyhydric alcohol with a boiling point of at least 150 DEG C coating on the surface of component (A) and/or component (B). The composite cured silicone powder that has an excellent flowability, hydrophilicity, and dispersibility. And, this invention also relates to a production method of the composite, which is characterized by mixing components (A) to (C) under the condition of mechanical shearing.
