Crospovidone (CAS 25249-54-1), also known as cross-linked povidone or PVPP, is a cross-linked homopolymer of N-vinyl-2-pyrrolidone. It appears as white or off-white hygroscopic powder, insoluble in water and common organic solvents, and swells rapidly without gelation upon contact with water. Widely used as an efficient disintegrant in tablets and capsules for both direct compression and granulation. In food industry, it clarifies wine and fruit juice by selectively adsorbing polyphenols and tannins, complying with major pharmacopoeia and food additive specifications.
High-Purity Crospovidone CAS 25249-54-1 Features
Cross-Linked Structure - Its three-dimensional polymer structure provides stable physical properties and maintains particle integrity during processing.
Insoluble in Water - Crospovidone does not form a viscous solution in water, making it suitable for formulations where rapid liquid uptake is required without increasing solution viscosity.
High Capillary Activity - The porous particle structure supports efficient liquid penetration throughout the material.
Low Moisture Sensitivity - Properly controlled moisture content helps maintain consistent handling and formulation performance during storage and production.
Good Flow Characteristics - Controlled particle size and morphology provide reliable powder handling and support consistent feeding during manufacturing.
High Purity Profile - Pharmaceutical-grade material is manufactured with controlled impurity levels to meet the requirements of regulated solid dosage production.
Particle Size Options - Different particle-size grades can be selected to match specific formulation, blending, and compression processes.
Consistent Batch Quality - Controlled raw materials and manufacturing parameters help maintain uniformity in key quality attributes from batch to batch.
Pharmaceutical-Grade Supply - We provide Crospovidone for pharmaceutical applications with controlled specifications and consistent quality, supporting routine production as well as formulation development.
Strict Quality Control - Each production stage is subject to defined quality controls, with key parameters monitored to maintain reliable batch-to-batch consistency.
Technical Support - Our team can provide product documentation, specification details, and technical information to assist customers with material evaluation and supplier qualification.
Stable Supply Capacity - We maintain organized production and inventory planning to support repeat orders and reduce supply interruptions for long-term customers.
Flexible Procurement Support - We work with pharmaceutical manufacturers, distributors, and formulation companies on different order volumes and provide practical support from sample evaluation to bulk purchasing.
Reliable Export Service - Professional packaging, documentation, and shipment coordination help ensure that Crospovidone orders are handled efficiently for international customers.
FAQ
Q: Can you provide a sample before a bulk order?
A: Yes. Samples can be arranged for customers who need to evaluate the material in their own formulation or manufacturing process before confirming a commercial order.
Q: How should Crospovidone be stored?
A: Crospovidone should be kept in a tightly closed package in a clean, dry environment, protected from excessive moisture, heat, and direct sunlight. Storage conditions should follow the applicable product specification.
Q: What information is needed when requesting a Crospovidone quotation?
A: Please provide the required grade or specification, estimated quantity, packaging preference, destination country, and any documentation requirements. This allows us to prepare a more accurate quotation and shipment plan.
Q: Can you support regular supply for pharmaceutical production?
A: Yes. For recurring requirements, we can coordinate production and delivery schedules according to the customer's purchasing plan, helping maintain continuity between orders and simplify long-term supply management.
