Polyvinyl pyrrolidone (PVP for short) is a non-ionic polymer compound, which is the most distinctive N-vinyl amide polymer
The deepest and most widely studied fine chemicals. It has developed into a series of homopolymers, copolymers and cross-linked polymers with a relative molecular weight ranging from thousands to more than one million in three categories of non-ionic, cationic and anionic, industrial, pharmaceutical and food grade, and has been widely used for its excellent and unique performance.
On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization (WHO) was preliminarily collated and referenced, and polyvinylpyrrolidone was included in the list of Category 3 carcinogens.
