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.
