Product Description
Product : Polyvinyl pyrrolidone
Synonym:PVP, PVP K, Povidone, PVP, Povidonum
CAS NO. 9003-39-8
Molecular formula:: (C6H9NO)n
Molecular structure:
Properties: Nontoxic; Non-irritant; Hygroscopic; Freely soluble in water, alcohol and most other organic solvents; Very slightly soluble in acetone; Excellent solubility; Film-forming; Chemical stability; Physiologically inert; Complexation and binding property.
Specifications, Based on the polymer molecular weight and viscosity in water, the current series products are classified based on their K-values.
Applications,
As solubilizer, it is suitable for oral and parenteral preparations, can improve the solubility of poorly soluble drugs in solid dispersions. It is also used as dispersant or crystallization inhibitor in liquid formulations.
As Binder, It is suitable for wet granulation and dry granulation, and is directly pressed in the tabletting process, which improves the compressibility of the granules. It can be added in dry or granular form by adding water, alcohol or water-alcohol solution Powder mixture. It also used as film-forming agent, solubilizer, suspension stabilizer, and dispersant in solid and liquid preparations.
Used as binder, thickener and suspension stabilizer in formulations.
Package: 25kg/drum
Shelf Life: 36 months
