Source – NKY

A high-purity, pharmaceutical-grade polymer widely used in the medical and chemical industries due to its excellent binding, film-forming, and stabilizing properties.
Below is a detailed technical description:
1. Chemical Profile
• Chemical Name: Polyvinylpyrrolidone (PVP)
• Generic Name: Povidone K-30
• CAS Number: 9003-39-8
• Molecular Formula: $(C_6H_9NO)_n$
• Appearance: White to off-white, hygroscopic (moisture-absorbing) powder.
• Molecular Weight: Approximately 40,000–60,000 Daltons.
2. Key Characteristics
• Solubility: Freely soluble in water and various organic solvents (alcohols, carboxylic acids). It is insoluble in lipids.
• pH Stability: Highly stable across a wide pH range (typically 3.0–7.0 in a 5% aqueous solution).
• Film Forming: Creates hard, transparent, and glossy films that are oxygen-permeable.
• Inertness: It is physiologically inert, non-toxic, and biocompatible, making it safe for oral and topical use.
3. Pharmaceutical Applications
• Tablet Binder: Primarily used in wet granulation and direct compression to hold tablet ingredients together.
• Solubility Enhancer: Improves the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Stabilizer: Prevents the degradation of active ingredients and stabilizes emulsions/suspensions.
• Coating Agent: Used in film-coating formulations for tablets and capsules to provide moisture protection and a professional finish.
• Injectables: Acts as a stabilizer in certain injectable solutions.
