The Kollidon range consists of soluble polyvinyl pyrrolidone which is obtained by radical polymerization of N-vinylpyrrolidone in water or isopropanol under cGMP conditions to yield the chain structure constituting polyvinylpyrrolidone (PVP). By virtue of it’s solubility in water and many organic solvents, it’s high binding power and ability to form complexes, soluble PVP occupies a special position among the synthetic colloids.

Kollidon is available in different grades on the basis of their K-value and molecular weight. All grades are supplied as almost white, free flowing, tasteless powders with a slight characteristic odour in pharmaceutically pure form.
