prilosec ingredients list polyvinylpyrrolidone what is it

pvp is polyvinylpyrrolidone. Polyvinylpyrrolidone (PVP) is a kind of non-ionic polymer compound. PVP is made from vinyl pyrrolidone (NVP) by bulk polymerization and solution polymerization. In the process of bulk polymerization, due to the viscosity of the reaction system, the polymer is not easy to diffuse, and the polymerization heat is not easy to remove, resulting in local overheating.

Therefore, the obtained product has low molecular weight, high content of residual monomer, and is mostly yellow, and has no great practical value. Solution polymerization is generally used to synthesize PVP in industry.

There are two main routes for the production of PVP polymerization, the first is the solution polymerization of N-2-pyrrolidone (NVP) in organic solvents, followed by steam stripping. The second route is aqueous polymerization of NVP monomer with water-soluble cation, anionic or non-ionic monomer.

A crosslinked homopolymer of pure vinylpyrrolidone. Polyvinylpyrrolidone (PVP) has the ability to bind to a variety of substances, such as the various pigments that cause wine and other beverages to discolor. And because of its insolubility, it is easy to be removed after filtration.

‌ polyvinylpyrrolidone has a wide range of uses and applications. It is produced by the polymerization of N-vinylpyrrolidone under certain conditions and belongs to one of the most distinctive N-vinylamide polymers. The relative molecular mass of PVP can range from thousands to more than one million, forming a series of products including homopolymers, copolymers and crosslinked polymers, which can be divided into industrial grade, pharmaceutical grade, food grade and other specifications according to different application needs.

PVP application areas
In the field of medicine: PVP is widely used in the field of medicine, including as a drug carrier, solvent, stabilizer and so on.
Daily chemicals: Used as additives in toothpaste, mouthwash and other daily chemicals to improve product performance and user experience.
New energy industry: especially in the field of ‌ lithium batteries, PVP is used as a dispersant for electrode materials and a processing aid for conductive materials to improve battery performance.
Other fields: PVP is also used in ‌ textile printing and dyeing, ‌ coating, ‌ beer and beverage, electronics, ‌ separation film and other fields.
PVP security
PVP is classified as a Group 3 carcinogen, but its safety has been widely recognized under normal conditions of use. Use should follow the relevant safe operating procedures and storage guidelines to ensure the safety of personnel and the environment.

Polyvinylpyrrolidone (PVP) is a multifunctional polymer whose unique physicochemical properties and wide application fields make it an indispensable part of the chemical industry.
