A Cationic Polymer are macromolecules that possess positive charges, which exhibits to be used for the purpose of dewatering organic sludge from sewage, human waste, etc. The cationic polymer has been employed commonly as drug delivery agents due to their superior encapsulation efficacy, enhanced bioavailability, low toxicity and improved release profile. . The key benefit of using Cationic Polymer is that it is economical to use effectively at very low dosage level and also performs well over a wide pH range.
