Product Description Product Description Polyvinyl Pyrrolidone (PVP) is a non-ionic polymer compound belonging to the N-vinylamide polymer class with unique properties and application range. The chemical formula of PVP is (C6H9NO)n and the molecular weight ranges from thousands to millions. The K value is often used to characterize its average molecular weight.Basic propertiesPVP is usually a white to light yellow amorphous powder with a slight odor. It is very soluble in water and a variety of organic solvents, such as halogenated hydrocarbon solvents, alcohols, amines, nitroalkanes and low molecular weight fatty acids, but insoluble in a few solvents such as acetone, ether, turpentine, aliphatic hydrocarbons and alicyclic hydrocarbons1. At room temperature and pressure, PVP has excellent chemical stability, is non-toxic to humans and animals, and has good physiological compatibility.Synthesis methodThe synthesis of PVP is mainly carried out by solution polymerization, where NVP monomer is placed in an organic solvent or aqueous solution and polymerized by adding an initiator. Different polymerization methods will affect the structure and properties of the polymer.Application fieldsFood field: As a food additive and stabilizer, it is used to improve the quality and taste of food.Cosmetic field: Using its film-forming and moisturizing properties, it is used as an additive and stabilizer for cosmetics.Water treatment field: As a flocculant and adsorbent, it is used in water treatment and purification processes.Other fields: It can be used as a surface coating agent, dispersant, thickener, and adhesive in daily cosmetics, pigments, printing inks, textiles, printing and dyeing, and color picture tubes.Safety and environmental protectionPVP is non-toxic to humans and animals and has good physiological compatibility. In addition, PVP degrades slowly in the environment, but it has high chemical stability and is not easy to decompose into harmful substances.In summary, polyvinyl pyrrolidone has become an important material in many industrial and medical fields due to its excellent solubility, physiological compatibility and wide application fields.
