Polyvinylpyrrolidone (PVP) for short is a non-ionic polymer compound. It is the most distinctive, and most deeply studied and widely studied fine chemical species among N-vinyl amide polymers. It has developed into 3 categories of non-ionic, cationic, and anionic, 3 specifications of industrial grade, pharmaceutical grade and food grade, and homopolymer, copolymer and cross-linked polymer series products with relative molecular mass ranging from thousands to more than one million, and has been widely used for its excellent and unique properties.
As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, such as colloid protection, film-forming, cohesiveness, hygroscopicity, solubilization, or agglomeration. People pay attention to its excellent solubility and physiological compatibility. Among synthetic polymers, it is rare that PVP is soluble in water and most organic solvents, with low toxicity and good physiological compatibility, especially in medicine, food, and cosmetics, which are closely related to people's health. In the field, with the reduction of the price of its raw material butyrolactone, it will show a good prospect for its development. The following is a specific introduction to its application areas:
Medicine & Health
PVP has excellent physiological inertia, does not participate in human metabolism, has excellent biocompatibility, and does not cause any irritation to the skin, mucous membranes, and eyes. Pharmaceutical Grade
PVP is one of the three major new pharmaceutical excipients advocated internationally. It can be used as a binder for tablets and granules, as a cosolvent for injections, as a glidant for capsules; Coating film-forming agent, dispersing agent for liquid preparations, stabilizer for enzymes and heat-sensitive drugs, and can also be used as a cryogenic preservation agent. Used in contact lenses to increase their hydrophilicity and lubricity. PVP K30 has been approved by the State Pharmaceutical Administration for the official launch.
