Kollidon CL

The insoluble grades of Kollidon® are widely used in the pharmaceuticals industry because of their swelling properties. They are thus predominantly used as disintegrants in solid oral dosage forms such as tablets. Furthermore their application as pharmaceutical excipients is triggered by their ability to hydrophilize insoluble drugs, to stabilize suspensions and to form complexes. Kollidon® CL Crosslinked Polymer is supplied as fine white or almost white powder. It has a slight characteristic odor and is practically tasteless. It is insoluble in all of the usual solvents. The insoluble grades of Kollidon® (Crospovidone) are manufactured by a polymerization process that yields crosslinked insoluble polyvinylpyrrolidone in the form of a “popcorn”polymer.
