Description: Polyvinylpolypyrrolidone , PVPP

Physical and Chemical Property: PVPP is hygroscopic,insoluble in water and all other common solvents,but it swells rapidly in aqueous solutbition without any gel froms.

Molecular Formula: C6H9NO

CAS No. 25249-54-1


Packing in 20kg drum

Application

PVP-P behaves as a white or creamy white powder with faint characteristic odor, which is easily hydrophilic and capable of complex with such substance as phenol, etc. It is completely insoluble with relatively high crosslink density and does not form gels that can impede disintegration, dissolution and drug release. It was accepted into Ph Eur 5.0 and USP/NF28th.
