PVP K15/17/25/30
Pharmaceutical-grade Povidone (PVP) available in K15, K17, K25 and K30 grades. This water-soluble polymer series supports wet granulation, tablet binding, liquid formulation stabilization, dispersion, film-forming and solubilization-support studies. Select the suitable grade based on required molecular weight, solution viscosity and formulation process.
Category: Povidone (PVP K Series)
CAS No.: 9003-39-8
Povidone K15, K17, K25 and K30 for Pharmaceutical Formulations
Yuking supplies Povidone, also known as Polyvinylpyrrolidone or PVP, in K15, K17, K25 and K30 grades for pharmaceutical formulation development and manufacturing.
Povidone is a water-soluble polymer used where binding, film-forming, stabilization, dispersion support or solubilization support is required. The most suitable PVP grade depends on the target dosage form, required solution viscosity, manufacturing process and expected formulation performance.

Povidone Grade Selection Guide
|
Grade |
K Value Range |
Viscosity-Average Molecular Weight |
Selection Direction |
|
Povidone K15 |
8,000–12,000 |
Consider for lower-viscosity formulations, oral liquids, dispersion systems and solubilization-support evaluation |
|
|
Povidone K17 |
10,000–16,000 |
Consider for low-to-moderate-viscosity systems requiring water-soluble polymer support |
|
|
Povidone K25 |
30,000–40,000 |
Consider for granulation, tablet binding and formulation stabilization studies |
|
|
Povidone K30 |
45,000–58,000 |
Consider for wet granulation, tablet binding, film-forming and pharmaceutical formulation stabilization |
The K value of Povidone is associated with molecular weight and solution viscosity. Lower K-value grades are generally considered where lower-viscosity polymer systems are needed, while higher K-value grades can provide stronger binding and greater viscosity support.
The final grade should be selected through laboratory trials and process validation, particularly for sensitive APIs, high drug loads, specialized solvent systems or modified-release formulation projects.
