PVP is a water-soluble polymer that is both miscible with water and soluble in many organic solvents such as alcohols, carboxylic acids, amines, halogenated hydrocarbons, etc. Film-forming properties: PVP has excellent film-forming properties, and can be poured or coated into films when dissolved in certain solvents such as water. Water absorption: PVP has strong water absorption and moisturizing properties, and is commonly used in cosmetics. Dispersibility and solubilization: Small molecule PVP has a good dispersing effect, preventing particles from aggregating and precipitating. PVP can increase the solubility of many substances in aqueous solutions. Complexity: The O and N atoms within PVP molecules are typical coordination atoms, giving them the ability to chelate with certain substances, such as iodine, benzene, amoline, and various sulfonamide drugs.
