Description: 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. CTFA Nomenclature : POLYVINYLPOLYPYRROLIDONE ( Abbreviated to be PVP-P) CAS No. : 25249-54-1 Chemical
