Description

Application

The Kollidon products consist of soluble and insoluble grades of polyvinylpyrrolidone (PVP) of various molecular weights and particle sizes. It is used as dry binders, film-formers, stabilizers in suspensions, dispersants for pigments, enzyme stabilisiers and bioavailablility improvers.
Kollidon SR is a blend of polyvinyl acetate and povidone (K 30) in the ratio 8:2 for use as matrix-forming agent. This research grade product is intended for use in R&D and development only.

Other Notes

Polyvinylpyrrolidone is a component of Denhardt′s Solution and is included at a concentration of 1% (w/v) in the standard 50X stock solution.
