Polyvinylpyrrolidone (PVP) is a polymer compound produced by the polymerization of N-vinyl-2-pyrrolidone.
This product is white to milky white powder; Odorless or slightly extra smelly, tasteless; It is moisture-inducing. This product is soluble in water, ethanol, isopropyl alcohol or trichloromethane, and insoluble in acetone or ether.
polyvinylpyrrolidone (PVP) is a non-ionic polymer characteristic of N-vinylamide polymers and a widely studied fine chemical variety. Has developed into non-ionic, cationic, anion 3 categories, industrial grade, food grade 3 specifications, relative molecular weight from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products. Polyvinylpyrrolidone PVP is divided into four stages according to its average molecular weight, which is usually expressed by the K value, and different K values represent the corresponding average molecular weight range of PVP. The K value is actually an eigenvalue related to the relative viscosity of PVP aqueous solution, and the viscosity is a physical quantity related to the molecular weight of polymers, so the average molecular weight of PVP can be characterized by K value. Generally, the greater the K value, the greater the viscosity and the stronger the adhesion.
Povidone K30(PVPK30) is widely used in medicine and is one of the three new pharmaceutical excipients advocated internationally. The most widely used adhesives are tablets and granules. PVP can also be used as a flow aid for capsules, a detoxifying agent and lubricant for eye drugs, a co-solvent for injections, a dispersant for liquid preparations, and a stabilizer for enzymes and heat-sensitive drugs. Povidone can also synthesize PVP-I disinfectant with iodine. PVP can also be used as a cryogenic preservative in medicine. There are hundreds of drugs using PVP products as excipients.
Using PVP’s good solubility, solubilization, physiological compatibility, bonding ability and complexation ability, it can be used as binder, excipient, coating agent, release agent, co-solvent, germicidal disinfectant, solubilizer, sustained-release agent, capsule shell, dispersion stabilizer, film forming agent and so on in the field of medicine and health. In some developed countries, such as the United States, Germany, Japan, etc., the application of PVP in the field of medicine and health accounts for about 40% to 55% of the total consumption of PVP.
