This study relates to the use of phase separation Microcapsulation for Chitosan and its mixture with the Polyethlene glycol.Chitosan and its mixture with the Poly-ethylene glycol can contribnte to wall material by variouss amounts o ratios,tween#80,NP-40,and glutaraldehyde under different stirring speed for encapsulation .Then,to find the compatibility conditions for chitosan/polyethylene glycol film and the feasi-bility of microcapsulation for chitosan /polyethylene glycol.
