Water soluble polymers are always being in good demand because of their certain advantages over organic solvents with respect to ecological, toxicological and manufacturing safety concerns, including Pollution, Explosion hazards, Risk of operators, High cost of organic solvents, solvent toxicity and many more. Aqueous polymeric dispersions, latexes, or pseudolatexs are all colloidal systems in which high molecular weight polymers are homogeneously dispersed in submicron sizes with the aid of surfactant(s) and other stabilizing agents. There are a wide range of water insoluble polymers includes Acryates: Eudragit, Cellulose: Ethyl cellulose, Vinylics: Polyvinyl acetate phthalate, Cellulosic esters: cellulose acetate phalate (CAP) & many more which provide a great research platform to develop an aqueous polymeric dispersions (APD) with the intention of conferring benefits and properties to the dosage form over the uncoated variety or organic coating. The present article is mainly focused on the theoretical & practical aspects of the development techniques/steps & research scope behind the development of APD.
