Polyvinyl pyrrolidone, or PVP for short, is a non-ionic polymer that is the most distinctive, best-studied and widely studied fine chemical among N-vinyl amide polymers. Has developed into non-ionic, cationic, anion 3 categories, industrial grade, pharmaceutical grade, food grade 3 specifications, relative molecular mass from thousands to more than one million homopolymer, copolymer and crosslinked polymer series products, and with its excellent unique properties have been widely used.

Medicine and health
PVP has excellent physiological inertia, does not participate in human metabolism, and has excellent biocompatibility, and does not form any irritation to the skin, mucous membranes, eyes, etc. Pharmaceutical grade PVP is one of the three new pharmaceutical excipients advocated internationally. It can be used as binder for tablets, granules, co-solvent for injections and flow aid for capsules. Detoxifying agent, delay agent, lubricant and coating film forming agent, dispersing agent of liquid preparation and stabilizer of enzyme and heat-sensitive drug, also can be used as cryopreservation agent. Used in contact lenses to increase their hydrophilicity and lubricity
Food processing
PVP itself is not carcinogenic, has good food safety, can form complexes with specific polyphenol compounds (such as tannins), and is mainly used as a food clarifying agent and stabilizer in food processing such as beer, juice, wine. PVP can form complexes with specific polyphenol compounds (such as tannins), so that it plays a clarifying and anti-coagulation role in fruit juice drinks.
Daily cosmetics
Because PVP has very low toxicity and physiological inertia, it is not irritating to the skin and eyes, and has a long-term use record in the field of medicine, so it is safe to use in cosmetics. In daily cosmetics, PVP and copolymer have good dispersion and film formation, PVP has a protective colloidal effect in emulsion, can be used in fat and non-fat paste, as a setting liquid, hair spray and mousse setting agent, hair care agent, shampoo foam stabilizer, wave setting agent and hair dye dispersant and affinity agent. Add PVP to cream, sunscreen and hair remover to enhance wetting and lubrication.
Abluent
PVP has anti-fouling reprecipitation performance, can be used to prepare transparent liquid or heavy dirt detergent, adding PVP in detergent has a good anti-color effect, and can enhance the cleaning ability, washing fabrics can prevent synthetic detergent on the skin stimulation, especially for synthetic fibers, this performance is more prominent than carboxymethyl cellulose (CMC) detergent. PVP can be combined with borax as an effective ingredient in the formulation of phenol-containing disinfectant detergent.
Textile printing and dyeing
PVP has a good affinity with many organic dyes, and it can be combined with hydrophobic synthetic fibers such as polyacrylonitrile, ester, nylon and fibrous materials to improve dyeing power and hydrophilicity. Kirsh Y E et al. reported that PVP and nylon grafted copolymerization produced fabrics with improved wet-wrinkle resistance and moisture resistance.
Paints and pigments
PVP coated paint, coating film transparent without affecting the color, improve the gloss and dispersion of paint and pigment, improve thermal stability and improve the dispersion of ink and ink.
Polymer surfactant
Polyvinylpyrrolidone, as a polymer surfactant, can be used as dispersant, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecipitating agent, coagulant, co-solvent and detergent in different dispersion systems.
Catalyst preparation
Stabilized colloidal particles as active agents are used in the preparation of core-shell catalysts.
Other aspects
PVP can be used as a gelling agent for tertiary oil recovery to improve oil recovery rate. As an additive for photosensitive materials, it helps to reduce the emulsibility and enhance the overlay ability of developed images. It is used as thickener, dispersion stabilizer and bond regulator in polymer polymerization. In the paper industry as a dispersant, it's used as a cocatalyst. The application of PVP in separation film, light curing resin, laser video disc, drag reducing coatings, building materials, steel making and electroplating is also rising.
