What is PVPP with cas 25249-54-1?
Polyvinylpyrrolidone cross-linked (PVPP) is a cross-linked polymer that is insoluble in water, strong acids, strong bases, and general organic solvents, formed by the polymerization of vinyl pyrrolidone monomers under specific conditions. As an important polymer fine chemical product, PVPP has many excellent and unique properties, and has been widely used in cosmetics, food, medicine and other fields.

Application
PVPP, as an important polymer fine chemical product, has many excellent and unique properties, and has been widely used in cosmetics, food, medicine and other fields. Due to the high molecular weight and cross-linking structure of cross-linked polyvinylketone, it is insoluble in water but can quickly cause its network structure to expand and undergo disintegration when encountering water. PVPP is widely used as a disintegration agent for tablets in medicine, as well as as a suspension stabilizer, a complexing agent for pharmaceutical components, and a complexing agent for tannins and polyphenols in plant-based drugs.
