Description
Polyvinylpyrrolidone (PVP) is a water-soluble polymer formed by the polymerization of N-vinylpyrrolidone monomers. Its chemical formula is (C₆H₉NO)ₙ and it has a linear or cross-linked polymer structure.
Properties
Solubility: Soluble in water and various organic solvents (such as ethanol and chloroform), insoluble in ethers.
Stability: Chemically inert, resistant to acids, alkalis, and salts, and partially decomposes at high temperatures.
Adhesion: Excellent film-forming and adhesive properties.
Safety: Non-toxic and non-irritating, with good biocompatibility, it is widely used in pharmaceuticals and cosmetics.
Applications
Pharmaceuticals: Used as a pharmaceutical excipient (adhesive, solubilizer), plasma substitute, and component of contact lens solutions.
Cosmetics: Hairspray, emulsion stabilizer, and thickener.
Industrial: Adhesives, coating additives, and textile printing and dyeing auxiliaries.
Other: Food processing (clarifier), 3D printing (adhesive), and electronics (battery separator material).
Common Types
Based on molecular weight, they are classified into the K series (e.g., K30, K90). The larger the molecular weight, the higher the viscosity.
