Polyvinylpyrrolidone Powder Introduction
Polyvinylpyrrolidone Powder is a polymer compound,it is formed by the polymerization of N-vinylpyrrolidone. Due to its different degrees of polymerization, it is divided into soluble PVP and insoluble PVPP. The appearance is white to slightly yellow powder, with excellent film-forming, adhesive, solubilizing, chelating, and physiological compatibility properties. It has good stability and low toxicity, and is widely used as an excipient and functional assistant in various fields such as medicine, cosmetics, and food.
