Polyvinylpyrrolidone(PVP)

Description: PVP-K Synonyms: Polyvinyl pyrrolidone, Povidone CAS No.: 9003-39-8 Molecular Formula: (C6H9NO)n sical properties: PVP exists in white powder or aqueous solution. PVP readily dissolves in water, alcohol, amine and halohydrocarbon, but is not dissolved in acetone and aether etc.. It has good solubility, biocompatibility, and siologically inert, film-forming character, colloid protect ability and compound ability to many organic or inorganic compounds. It is also steady to acid, salt and heat, so it is widely used.

Low molecular weight PVP-K, often used as a solubilizing agent, crystallization inhibitor and suspension stabilizer in injection and ohalmic formulations such as PVP K12,K15,K17. Medium Molecular PVP-K, often used as binder in tablets,capsules and granules, as a stabilizer for oral suspensions,film-forming agent,solubilizing agent, dispersant for pigments, as an enzyme stabilizer and to improve bioavailability such as PVP K25,K30. High molecular PVP-K, as highly effective binder, often used as stabilizer in oral and topical suspension, as a thickener, hydropylizing agent such as PVP K90.
