As a synthetic water-soluble polymer compound, PVP has the general properties of water-soluble polymer compounds, colloidal protection, film formation, adhesion, hygroscopic, solubilization or condensation, but its most distinctive, so people pay attention to its excellent solubility and physiological compatibility. In synthetic polymers such as PVP both soluble in water, but also soluble in most organic solvents, very low toxicity, good physiological compatibility is rare, especially in medicine, food, cosmetics, which are closely related to people's health in the field, with the reduction of the price of its raw material butyrolactone, will show its good prospects for development.
