PVP K30 (CAS 9003-39-8): Versatile Polyvinylpyrrolidone Polymer for Advanced Formulations
PVP K30, chemically known as Polyvinylpyrrolidone K30 or Povidone K30 (CAS 9003-39-8), is a non-ionic, water-soluble polymer synthesized from N-vinylpyrrolidone monomer. Defined by its characteristic K-value range of 27.0 to 32.0, PVP K30 exhibits a mean molecular weight of approximately 45,000 to 55,000 g/mol, offering an optimal balance between binding strength and solution viscosity.
As a highly versatile excipient and industrial additive, PVP K30 is widely recognized for its superior solubility in water and polar organic solvents (such as ethanol and isopropanol), high hygroscopic binding capacity, outstanding film-forming ability, and physiological inertness. It serves as an essential functional component across pharmaceutical wet granulation, personal care hair styling gels, membrane manufacturing, and technical industrial coatings.

Compendial Compliance: Available grades conform to current USP/NF (United States Pharmacopeia), EP (European Pharmacopoeia), and JP (Japanese Pharmacopoeia) specifications for Povidone.
REACH & Global Inventories: Full REACH registration compliance for European distribution, along with inclusion in major global chemical inventories (TSCA, IECSC, DSL, AICS).
Regulatory Dossier Package: Comprehensive documentation support provided with each shipment, including Safety Data Sheets (SDS) according to GHS, Certificate of Analysis (COA), Nitrosamine Risk Assessment, BSE/TSE-Free Certificates, and Halal/Kosher declarations.
Product Packaging
Our analytical testing laboratory performs rigorous quality control testing on every batch of PVP K30 (CAS 9003-39-8) prior to warehouse clearance, safeguarding formulation stability and chemical purity.
K-Value & Viscosity Measurement: Determined via capillary viscometry of a 1.0% w/v aqueous solution at 25°C to ensure tight adherence to the specified range (27.0–32.0).
Residual Monomer (N-Vinyl-2-pyrrolidone) Analysis: Quantified using High-Performance Liquid Chromatography (HPLC) to guarantee residual NVP levels remain strictly controlled below 10 ppm.
Moisture Content / Loss on Drying: Measured via Karl Fischer titration or thermogravimetric loss-on-drying methods to keep moisture below 5.0%.
Heavy Metals & Impurity Screening: Analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to ensure heavy metal traces (such as Lead, Arsenic, and Cadmium) comply with stringent pharmacopeial thresholds.
Sulfated Ash & Peroxide Value: Monitored via wet chemical analytical standards to verify low ionic contamination and high oxidative stability in liquid solutions.
PVP K30 is utilized across diverse industry sectors due to its dual hydrophobic/hydrophilic chemical architecture:
Pharmaceutical Tablet & Granules Binder: Acts as a highly effective wet granulation binder and dry binder, enhancing granule compressibility, tablet hardness, and dissolution rates in oral solid dosage forms.
Solubilization & Bioavailability Enhancement: Serves as a solid dispersion carrier for poorly soluble Active Pharmaceutical Ingredients (APIs), preventing crystallization and increasing dissolution velocity.
Personal Care & Cosmetics: Functions as a film-forming and setting agent in hair fixatives, gels, mousses, and skin lotions, providing clean hold without flaking.
Industrial Applications:
Membrane Manufacturing: Functions as a pore-forming agent in polysulfone (PSU) and polyethersulfone (PES) ultrafiltration membranes.
Coatings & Inks: Acts as a pigment dispersant and binder in water-based inks, dye-receptive coatings, and adhesive formulations.
Recommended Usage Guidance:
Pharmaceutical wet granulation binder: 2.0% – 5.0% (w/w)
Hair care setting gel film-former: 1.0% – 6.0% (w/w)
Industrial dispersant/stabilizer: 0.5% – 3.0% (w/w)
FAQ
A: The primary difference lies in molecular weight and solution viscosity. PVP K30 (MW ~50,000 g/mol) exhibits lower solution viscosity, making it optimal for wet granulation binding, tablet dissolution, and spray-drying applications. PVP K90 (MW ~1,200,000 g/mol) forms significantly thicker gels and offers superior film-strength, making it preferred for high-viscosity adhesives or specialized hair fixatives.
A: Yes, PVP K30 readily absorbs atmospheric moisture under humid conditions. It should be stored in tightly sealed, moisture-proof containers (e.g., polyethylene-lined drums) in a dry, cool warehouse away from direct heat sources and excessive humidity.
A: Yes. PVP K30 possesses amphiphilic solubility, dissolving readily in water as well as alcohols (ethanol, isopropanol) and chlorinated hydrocarbons. This dual solubility profile allows formulators to create clear hydro-alcoholic solutions or specialized solvent-based systems smoothly.
