What Is Polyvinylpyrrolidone

Polyvinyl pyrrolidone, referred to as PVP, is a non-ionic polymer compound. It is the most distinctive, most deeply and extensively studied fine chemical among N-vinyl amide polymers. It has developed into a series of homopolymer, copolymer and cross-linked polymer products in three categories: non-ionic, cationic and anionic, three specifications of industrial grade, pharmaceutical grade and food grade, with relative molecular weights ranging from thousands to more than one million. , and has been widely used for its excellent and unique properties.
On October 27, 2017, the World Health Organization's International Agency for Research on Cancer released a preliminary reference list of carcinogens, and polyvinylpyrrolidone was included in the list of Class 3 carcinogens.
