What is PVPP

Crosslinked polyethylpyrrolidone (PVPP) is a kind of crosslinked polymer, which is insoluble in water, strong acid, strong base and general organic solvent, and is white or milky powder or particle.

Crosslinked POvidone is one of the three super disintegrators, but it can not only be widely used as medicinal excipients in pharmaceutical preparations, but also as a food additive used in the processing and production of beer, red wine, juice and other drinks, so it has another name – insoluble polyethylpyrrolidone (PVPP).
