PVP K-90 (Polyvinylpyrrolidone K-90) is a high molecular weight synthetic polymer with a K-value of 81.0–97.2% and a pH value in water of 5–7. As the highest molecular weight grade in the PVP family, PVP K-90 delivers superior film-forming, binding, and adhesion properties — making it the preferred grade for hair styling products requiring maximum hold, hair sprays, and pharmaceutical tablet binding applications where high viscosity and strong film strength are required.
Applications:
- Hair Styling (maximum hold hair gels, hair sprays, styling mousses)
- Pharmaceutical Tablets (tablet binder for oral solid dosage manufacturing)
- Personal Care (waterproof mascara and eye cosmetics, long-wearing makeup formulations)
- Industrial & Specialty (adhesive formulations, membrane coatings)
Key Features & Benefits:
- K-value 81.0–97.2%, pH 5–7 – high molecular weight film-forming polymer
- Maximum hold performance for premium hair styling formulations
- Strong film-forming and adhesion properties for long-wearing cosmetics
- Excellent pharmaceutical tablet binding capability
- Water-soluble and easily removed with normal washing
