polyvinylpyrrolidonit

Polyvinylpyrrolidone, often abbreviated as PVP, is a synthetic polymer derived from vinylpyrrolidone. Its solubility in water and various organic solvents makes it a versatile material. PVP is a non-ionic polymer, meaning it does not carry an electrical charge. It is typically produced through the polymerization of N-vinylpyrrolidone monomer.

The physical properties of PVP can vary depending on its molecular weight. Lower molecular weight grades are typically viscous liquids, while higher molecular weight grades are solid powders. PVP is known for its excellent film-forming capabilities, as well as its binding, dispersing, and solubilizing properties. It is also considered to be non-toxic and biocompatible.

PVP finds widespread application in various industries. In the pharmaceutical sector, it is used as a binder in tablets, a disintegrant, and a solubilizer for poorly soluble drugs. In cosmetics and personal care products, it acts as a film-former in hair sprays and styling gels, and as a thickener in creams and lotions. PVP is also utilized in industrial applications, such as in adhesives, coatings, and as a clarifying agent in beverages like beer and wine. Its ability to complex with various substances contributes to its diverse uses.
