Details
Product Properties: Povidone is a hygroscopic polymer ,supplied in white or creamy white powder or flakes,ranging from low to high viscosity & low to high molecular weight,which characterized by K Value.It’s easily soluble in water and many other organic solvents,with excellent hygroscopisty,film-forming,adhesive,chemical stability and toxicological safeness characters.
Applications:Povidone is one of the most important excipient in the worldwide for pharmaceutical industry,whatever for human health care products and animal health care products.It’s more and more used as:1)Binder for tables,capsule,2)Sugar coatings and films,3)Thickening agent,4)Solubility Improver for poorly soluble drugs,5)Bioavailability Enhancer for drug’s active ingredients,6)Pore-forming for membrane products.
