Product use

1) Due to its high molecular weight and cross-linked structure, cross-linked polyvinylpyrrolidone is insoluble in water, but its network structure can quickly expand and disintegrate when it comes into contact with water. It is widely used as a disintegrant for tablets in medicine. It is also widely used as a suspension stabilizer, a complexing agent for drug ingredients, and a complexing agent for tannins and polyphenols in botanical drugs.

2) Cross-linked polyvinylpyrrolidone (PVP-P) can form complexes with phenols and alkaloids, thereby removing them from plant samples, thus preventing modification and interference with proteins, so as to more accurately determine the protein content. It has also been reported that cross-linked polyvinylpyrrolidone (PVP-P) can increase enzyme activity.
