What is polyvinylpyrrolidone used for?  

The water-soluble polymer polyvinylpyrrolidone (PVP), also known as polyvidone or povidone, is created from the monomer N-vinylpyrrolidone. PVP can be chosen based on the desired application qualities and is offered in a variety of molecular weights and associated viscosities.

Medical Uses

Many medicinal tablets include polyvinylpyrrolidone as a binder; when consumed orally, it just passes through the body.

Povidone-iodine, a compound formed when PVP and iodine are combined, is a disinfectant. This compound is utilized in a number of goods, including surgical scrubs, liquid soaps, pessaries, solutions, and ointments. It is offered for sale under several trade names, including pyodine and betadine.

It is employed in pleurodesis, which involves fusing the pleura due to persistent pleural effusions. Povidone iodine is just as efficient and secure for this usage as talc, and because it's so accessible and affordable, it can be favored.Some contact lens solutions and packaging materials include PVP. It acts as a lubricant or wetting agent integrated into the lens by reducing friction. Examples of this application include Air Optix contact lens packing solution (which contains the chemical known as "copolymer 845") and Bausch & Lomb's Ultra contact lenses with MoistureSeal Technology.

Technical Uses

PVP is also used in many technical applications.

As a special additive for batteries, ceramics, fiberglass, inks, and inkjet paper, and in the chemical-mechanical planarization process.

As an emulsifier and disintegrant for solution polymerization.

To increase resolution in photoresists for cathode ray tubes (CRT).

For the production of membranes, such as dialysis and water purification filters.

As a binder and complexation agent in agricultural applications such as crop protection, seed treatment, and coating.

As a thickening agent in tooth whitening gels.

As an aid for increasing the solubility of drugs in liquid and semi-liquid dosage forms (syrups, soft gelatine capsules) and as an inhibitor of recrystallization.

As a surfactant, reducing agent, shape-controlling agent, and dispersant in nanoparticle synthesis and their self-assembly.

As a stabilizing agent in all inorganic solar cells.

Other uses

Due to its polarity, PVP bonds to polar molecules particularly effectively. Due to this, it is now used in inks for inkjet printers as well as coatings for photo-quality ink-jet sheets and transparencies.PVP is also utilized in paints, personal care goods like toothpaste and shampoo, and moistenable adhesives like those seen in vintage postal stamps and envelopes. Additionally, it has been utilized in steel quenching and contact lens treatments. PVP served as the foundation for early hair gel and spray compositions and is still present in some of them now.PVP can be used to create an aqueous mounting medium for microscopy.
