High Quality Pharmaceutical Excipients PVP Polyvinylpyrrolidone K-30 CAS 84057-81-8
Polyvinylpyrrolidone(PVP), a non-ionic polymer, is one of the most distinctive, well-studied and widely studied fine chemicals in N-vinylamide polymers. Has developed into non-ionic, cationic, anionic 3 categories, industrial grade, medical grade, food grade 3 specifications, relative molecular weight from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used.
Function:
PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not cause any irritation to the skin, mucous membranes, eyes, etc. Pharmaceutical grade PVP is one of the three new pharmaceutical excipients advocated internationally, which can be used as binder for tablets, granules, co-solvent for injections and flow aid for capsules. Ophthalmic detoxification agent, delay agent, lubricant and coating film agent, liquid preparation of dispersing agent and enzyme and heat-sensitive drug stabilizer, also can be used as cryoppreservation agent. For contact lenses, can increase its hydrophilicity and lubricity.
