Polyvinylpyrrolidone (PVP) is a water-soluble synthetic polymer renowned for its exceptional binding, film-forming, and stabilizing properties. It is widely used in pharmaceuticals, cosmetics, food, and industrial applications due to its biocompatibility, chemical stability, and versatility.
PVP is classified by K-value (a measure of molecular weight and viscosity). Common grades include:
| Grade | K-Value | Avg. MW (Da) | Viscosity (10% aq. sol.) | Primary Applications |
|---|---|---|---|---|
| PVP K15 | 12-18 | ~10,000 | 1.5-3.0 mPa·s | Instant-release tablets, spray-drying aids |
| PVP K17 | 15-19 | ~12,000 | 2.0-4.0 mPa·s | Oral liquids, adhesives |
| PVP K25 | 22-28 | ~34,000 | 5.0-8.0 mPa·s | Tablet binders, coatings |
| PVP K30 | 27-33 | ~50,000 | 8.0-12 mPa·s | Pharma coatings, beer clarification |
| PVP K90 | 85-95 | ~1,300,000 | 300-700 mPa·s | Sustained-release drugs, hairspray |
PVP's adaptability across industries stems from its tunable properties (via K-value selection). Whether for rapid drug release (K15) or long-lasting films (K90), PVP delivers consistent performance.
