Abstract: Cellulose ether powder is prepared in a safe and easy way by first adding a surfactant solution to surfaces of water-soluble cellulose ether particles, and then adding a tannin solution thereto. The powder thus prepared is free of bitterness and readily dissolvable in cold water without forming clumps.

Abstract: A composition comprising 10-80% by weight of a cellulose ether and a solvent selected from a water-soluble polyhydric alcohol, polyhydric alcohol ether, polyhydric alcohol ester, and ethanolamine is effective for purging extrusion and injection molding machines. The purging composition exerts a satisfactory purging or cleaning effect, but little abrasion effect, thus avoiding any abrasion of machine internal components by purging. Even if part of the purging composition is left within the machine after the composition is discharged out, the residue can be readily removed.
