About Polyvinylpyrrolidone

Polyvinylpyrrolidone
CAS number [9003-39-8]

Polyvinylpolypyrrolidone (PVPP, crospovidone) is a highly cross-linked modification of PVP.
The monomer is extremely toxic to aquatic life. However, the polymer PVP was used as a blood plasma expander for trauma victims after the first half of the 20th century.[clarification needed]

It is used as a binder in many pharmaceutical tablets; it simply passes through the body when taken orally. However, autopsies have found that crospovidone does contribute to pulmonary vascular injury in substance abusers who have injected pharmaceutical tablets intended for oral consumption. The long-term effects of crospovidone within the lung are unknown. PVP added to Iodine forms a complex called (Povidone-iodine) that possesses disinfectant properties. This complex is used in various products like solutions, ointment, pessaries, liquid soaps and surgical scrubs. It is known for instance under the trade name Betadine.

PVP binds to polar molecules exceptionally well, owing to its polarity. This has led to its application in coatings for photo-quality ink-jet papers and transparencies, as well as in inks for inkjet printers.

Exceptional Versatility and Purity

With a purity of 99%, polyvinylpyrrolidone guarantees consistent results across various industries. As a synthetic solid, it integrates seamlessly into formulations for pharmaceuticals, cosmetics, adhesives, and the food industry, meeting high-quality industrial standards.

Reliable Packaging and Shelf Life

Packaged in bottles or bags, each batch is sealed to maintain freshness and product integrity. The powder form ensures ease of handling, and the two-year shelf life offers convenience for bulk users and long-term projects alike.

Solubility and Odorless Attributes

One of the key benefits of PVP is its excellent solubility in water and ethanol, facilitating smooth blending into diverse formulations. Being odorless and free from protein or fat, it is suitable for sensitive applications requiring clean, interference-free additives.

FAQs of Polyvinylpyrrolidone:

Q: How should polyvinylpyrrolidone powder be stored to maintain its quality?

A: Polyvinylpyrrolidone should be stored in a cool, dry environment within its sealed packaging to prevent moisture absorption and ensure it remains free-flowing and effective throughout its two-year shelf life.

Q: What industries commonly use polyvinylpyrrolidone, and why?

A: This product is widely utilized in pharmaceuticals, cosmetics, adhesives, and the food industry due to its high purity, solubility in water and ethanol, and inert, odorless nature, making it suitable for sensitive formulations.

Q: When is polyvinylpyrrolidone typically added during manufacturing processes?

A: PVP is generally introduced during the mixing or blending stages of product formulation, ensuring smooth dispersion thanks to its powder form and solubility.

Q: Where is your polyvinylpyrrolidone manufactured and exported from?

A: Our polyvinylpyrrolidone is manufactured, supplied, and exported directly from China, adhering to industrial grade standards for global distribution.

Q: What process is used to ensure the purity and quality of the polyvinylpyrrolidone provided?

A: Stringent quality control measures are implemented during synthesis, packaging in sealed bottles or bags, and regular testing to confirm 99% purity, controlled moisture content, and adherence to industrial standards.

Q: How is polyvinylpyrrolidone beneficial in pharmaceutical and cosmetic applications?

A: In pharmaceuticals, PVP acts as a binder and solubilizer, while in cosmetics it stabilizes formulations and enhances texture, providing reliable, consistent performance due to its chemical inertness.

Q: What are the recommended uses for this polyvinylpyrrolidone powder?

A: This PVP powder is recommended for industrial formulation in pharmaceuticals, cosmetics, adhesives, and food products, owing to its excellent solubility, stability, and purity.
