Polyvinylpyrrolidone K Series
PVP K
Product name: Povidone
USP name: Povidone
EP name: Povidonum
INCI/CTFA: Polyvinylpyrrolidone(PVP)
CAS No.: 9003-39-8
Properties: Nontoxic; Non-irritant; Hygroscopic;
Freely soluble in water, alcohol and most other organic solvvents;
Very slightly soluble in acetone
Excellent solubility; Film-forming; Chemical stability;
Physiologically inert; Complexation and binding property.
Specification: Based on the polymer molecular weight and viscosity in water, the current series products are classified based on their K-values.
Product | K-Value* | Mv** | Main application |
K12 | 10.2-13.8 | 3,000-7,000 | Used as a solubilizer, dispersant and anti-crystallization agent in liquid dosage applications. |
K15 | 12.75-17.25 | 8,000-12,000 | |
K17 | 15.3-18.36 | 10,000-16,000 | |
K25 | 22.5-27.0 | 30,000-40,000 | Used as a binder, film-forming agent, solubilizer, suspension stabilizer and dispersant in dosage form applications. |
K30 | 27-32.4 | 45,000-58,000 | |
K60 | 54-64.8 | 270,000-400,000 | Used as a binder, thickener or suspension stabilizrer in dosage form applications. |
K90 | 81-97.2 | 1,000,000-1,500,000 | |
*K-value is calculated by viscosity of 1% water solution, also can be used to calculate Mv through Mark-Houwink formulation. **Mv is viscosity-average molecular weight. | |||
The addition of PVP K30 to HPMC film coating solutions can effectively reduce the viscosity of the HPMC solution while not affecting the resultant hydration profile of the resultant film. | Puerarin povidone solid dispersions dissolution curve
Puerarin - PVP K30 solid dispersions can accelerate the dissolution of puerarin rate significantly. | |||||||
