Polyvinylpyrrolidone (PVP) is a synthetic, water-soluble polymer widely used across pharmaceuticals, cosmetics, food, and industrial applications. It is valued for its biocompatibility, film-forming ability, and compatibility with both hydrophilic and hydrophobic compounds, making it an excellent binder, stabilizer, and coating material in formulations where traditional polymers would be inadequate. Engineers select PVP when water solubility, non-toxicity, and adhesive properties are critical—particularly in regulated industries where material safety and regulatory approval are prerequisites.
