KOLLIDON

Povidone USP/NF, EP, JP

 

The soluble grades of Kollidon are polyvinylpyrrolidone (PVP K) obtained by free-radical polymerization of N-vinylpyrrolidone. By virtue of its solubility in water and many organic solvents as well as its high binding power and ability to form complexes, soluble PVP occupies a special position among the synthetic colloids.

Soluble Kollidon is available in a variety of grades based on their K-value and weight average molecular weight.
