Polyvinylpyrrolidone cross-linked Usage
1. PVPP For the beverage, pharmaceutical industry
2. Due to the high molecular weight and crosslinked structure of crospovidone, it is insoluble in water, but it can rapidly promote its network structure to swell and cause disintegration. It is widely used as a disintegrant for tablets in medicine and is widely used as a disintegrator. Suspension stabilizer, drug component complexing agent, complexing agent for tannin and polyphenolic substances in botanical drugs
3. Cross-linked polyvinylpyrrolidone (PVP-P) forms a complex with phenols and alkaloids to remove them from plant samples, thus preventing protein modification and interference, in order to more accurately determine protein content. . It has also been reported that cross-linked polyvinylpyrrolidone (PVP-P) can increase the activity of the enzyme…
