Poly Vinyl Pyrrolidone Uses

Polyvinylpyrrolidone, referred to as PVP, is a non-ionic water-soluble polymer compound. It is the most characteristic, most deeply studied and widely studied fine chemical variety among N-vinylamide polymers. At present, it has developed into three categories of non-ionic, cationic and anionic, three grades of industrial grade, pharmaceutical grade and food grade, and a series of homopolymers, copolymers, cross-linked polymers and molecular complexes with molecular weights ranging from thousands to more than one million. It is widely used in industries and scientific research departments around the world with its excellent and unique properties, and still publishes more than 200 papers each year to show its ascendant status and prospects for continued development.

Pharma
The excellent physiological compatibility of PVP has attracted the attention of the medical community since its launch. Today, PVP has become a major synthetic drug excipient and is widely used throughout the world. It is included in the pharmacopoeias of Europe, the United States, Russia, Japan, China and other countries, and is accepted by health administrative departments of almost all countries in the world.
Industrial
PVP is a high molecular surfactant. It has hydrophilic and lipophilic groups in its molecular structure and good bonding ability to the surface of solid particles, so it can change the state of the interface or solution. It can be used as a dispersant, stabilizer, emulsifier, thickener, leveling agent, particle size regulator, anti-reprecipitation agent, coagulant, cosolvent and detergent aid. It can be used in solid glue, coatings, pigments, water treatment membranes, etc.
Cosmetics
Povidone is used in moisturizers and creams for its film-forming properties, which help to lock in moisture and create a protective barrier on the skin.
Food & Beverage
PVP and insoluble PVP can be used as clarifiers and stabilizers for beer, wine, and juice in the brewing and beverage industries, and have been legally permitted to be used in production in 38 countries around the world. Low-alcohol wine brewed with plant materials such as barley, rice, hops, etc. is rich in a variety of protein polyphenols.
Water Treatment
PVP K series products have a good pore-forming effect. Nowadays, membrane separation sewage treatment and water purification technology has become the mainstream technology in this industry. K90, K85 and K30 in the PVP K series are widely used as pore-forming agents in the water treatment industry.
Oral Care
The complexing and dispersing abilities of PVP can increase the detergency of toothpaste. Colgate's patent shows that adding a small amount of PVP has a significant effect on the detergency of toothpaste.
Other Application
PVP can be used as a dispersant for lithium battery cathode materials and as porogen.
