Molecular Formula: (C6H9NO)n
Appearance: White powder or aqueous.
Solubility: PVP is diffluent in water, alcohol, amine and halohydrocarbon, but is not dissolved in acetone and aether etc.. It has good solubility, biocompatibility, and physiologically 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.

Povidone K products possess excellent adhesive, film-forming, dispersing and thickening properties,which are widely used in the pharmaceutical industry. They are one of the three main accessory products recognized & approved worldwide.
1. Low molecular weight Povidone K, for use as a solubilizing agent, crystallization inhibitor and suspension stabilizer in injectables and ophthalmic formulations. Such as Povidone K12, K15, K17.
2.Medium Molecular Povidone K, for use 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 imrove bioavailability .Such as PovidoneK25, K30.
3.High molecular Povidone K, a highly effetive binder, for us as stabilizer in oral and topical suspensions, as a thickene.Such as Povidone K60, K90.
