What is PVP K15? Comprehensive Guide to Polyvinylpyrrolidone K15

PVP K15, or Polyvinylpyrrolidone K15, is a low molecular weight synthetic polymer widely used as a pharmaceutical excipient, solubilizer, and binder. With a K-value of 12-18, it offers exceptional water solubility and low viscosity, making it ideal for oral and parenteral formulations. As a leading PVP K15 supplier to the USA market, Shijiazhuang Standard IMP&EXP CO.,LTD. provides pharmaceutical-grade PVP K15 compliant with USP-NF, EP, and JP pharmacopeias.

Polyvinylpyrrolidone (PVP) is a hydrophilic polymer derived from the monomer N-vinyl-2-pyrrolidone through free-radical polymerization. The "K15" designation refers to its Fikentscher K-value, a measure of molecular weight and viscosity. PVP K15 typically has a weight-average molecular weight of 8,000-12,000 Da, distinguishing it from higher grades like PVP K30 (40,000-60,000 Da) or PVP K90. This low MW profile ensures rapid dissolution in aqueous media—critical for immediate-release tablets and injectables.

In pharmaceutical applications, PVP K15 powder excels as a solubilizer for poorly water-soluble APIs (active pharmaceutical ingredients). It forms complexes via hydrogen bonding, enhancing bioavailability. For instance, studies show PVP K15 increases the solubility of drugs like ibuprofen by up to 5-fold (source: Journal of Pharmaceutical Sciences, 2022). It's also a premier binder in wet granulation, improving tablet hardness without prolonging disintegration time.

Beyond pharma, PVP K15 serves in cosmetics as a film-former in hair sprays and mucoadhesive in oral care products. In the food industry, it's used as a clarifier for beverages, though our focus is pharmaceutical intermediates. Our production adheres to CGMP standards, using high-purity monomers to achieve <1 ppm heavy metals and residual vinylpyrrolidone levels below 10 ppm—far exceeding regulatory limits.

Key properties of PVP K15 include:

• Appearance: White to off-white hygroscopic powder
• Solubility: Freely soluble in water (up to 100 mg/mL), ethanol, methanol
• pH (5% solution): 3.0-7.0
• Viscosity (5% in water): 1.5-3.0 mPa·s
• Ash content: ≤0.1%
• Nitrogen content: 11.5-13.5%

Compared to competitors, our PVP K15 wholesale offers superior purity (99.5% min.) at competitive pricing, addressing pain points like high prices from Western suppliers (up to 50% markup) and inconsistent quality from unregulated sources. We leverage China's efficient supply chain for high-speed delivery—FOB Tianjin in 7-10 days to USA ports.

Regulatory compliance is paramount for USA buyers. Our PVP K15 holds DMF (Drug Master File) with US FDA, ensuring seamless ANDA/NDA filings. It's free from BSE/TSE, GMO, and meets REACH for EU exports. In real-world use, PVP K15 enables amorphous solid dispersions (ASDs) for BCS Class II/IV drugs, boosting dissolution rates by 3-10x (Pharm. Res. 2023).

Manufacturing at our 50,000 sqm facility involves advanced polymerization reactors, vacuum drying, and micronization for uniform particle size (50-100 μm). Quality control includes HPLC for residual monomers, GC for solvents, and ICP-MS for impurities. Batch consistency is 99.8%, per our ISO 9001:2015 certification.

For OEM/ODM, we customize K-values, particle sizes, or blend with PVP K30 for tailored viscosities. Export data: Over 500 MT annually to USA pharma giants, with zero recalls. Ready to optimize your formulations? Download our PVP K15 brochure now.

Your Top Challenges Sourcing PVP K15 in the USA Market

As a purchasing manager or technical director, you face mounting pressures. Here's how high price, low quality, high shipping costs impact your operations:

1. Premium Pricing from US/EU Suppliers: PVP K15 costs $25-35/kg domestically—40% higher than necessary, eroding ROI on generics.
2. Quality Inconsistencies: Off-spec batches cause failed dissolutions (15% rejection rate per FDA data), delaying launches by 6 months.
3. Prohibitive Shipping Costs: Air freight from Europe: $5-8/kg; ocean delays 30-45 days, tying up $100K+ inventory.
4. Supply Chain Disruptions: Competitors' reliance on single sources led to 2023 shortages (up 25% price spike).
5. Regulatory Hurdles: Non-DMF grades trigger FDA holds, costing $50K per validation.
6. Customization Gaps: Rigid specs don't fit your injectables or ASDs.

Scenario: Your last order arrived with 2% excess moisture, ruining 20% batch. Don't let this continue. Discover our solution below.
