Some Knowledge of Kollicoat IR

Kollicoat IR is a polyvinyl alcohol-polyethylene glycol graft copolymer with the addition of colloidal silica. It is a water soluble film forming agent, ideal for manufacturing instant release coatings for solid dosage forms. The important features of this innovative excipient are low viscosity of the polymer solution, outstanding flexibility of the film coating without the addition of plasticizers and extremely rapid coating dissolution in the body. In case of viscosity alone, this new technology offers wonderful advantages over cellulose derivatives.

Kollicoat IR is widely applied in the pharmaceutical industry as a binder and for instant-release coating of tablets, pellets, and particulate matter.Kollicoat polymers can be employed as film coatings with controlled-release agents, for instant-release, enteric or sustained-release applications. Kollicoat polymers can be served with all standard coating equipment and are cost-effective, delivering maximum quality in terms of function, stability, and appearance.
