Polyvinylpyrrolidone K30 (CAS 9003-39-8), abbreviated as PVP K30, is a water-soluble polymer. It appears as white powder, readily soluble in water and alcohols. Featuring good film-forming, solubilizing and dispersing properties, it is chemically stable and non-irritating. Widely applied in pharmaceutical preparations, cosmetics, food and chemical industries, it serves as binder, solubilizer, film former and suspension stabilizer.
High-Purity Polyvinylpyrrolidone K30 CAS 9003-39-8 Details
K Value: Typically around 27–32, indicating a medium molecular-weight grade suitable for general formulation use.
Appearance: White to off-white powder with uniform particle characteristics.
Solubility: Readily soluble in water and compatible with polar solvents used in pharmaceutical processing.

FAQ
Q: Is PVP K30 suitable for wet granulation?
A: Yes. PVP K30 can be used as a binder in wet granulation processes. Its solution properties allow it to be incorporated into the granulating liquid and distributed through the powder bed during processing.
Q: Can you provide a sample before bulk purchase?
A: Yes. Samples can be arranged for formulation trials and quality evaluation before commercial orders. The sample specification and quantity can be discussed according to the customer's testing requirements.
Q: How should PVP K30 be stored after delivery?
A: Keep the product in its original sealed packaging in a cool, dry and well-ventilated area. Avoid prolonged exposure to humidity and reseal the package promptly after opening.
Q: Can the packaging be customized for bulk orders?
A: Packaging options can be discussed according to order volume, transportation requirements and the customer's warehouse handling procedures. Product labeling and batch traceability can also be coordinated accordingly.
