ConclusionThe product complies with the Current version of the EP standard
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.
