Polyvinylpyrrolidone (PVP) is a versatile, water-soluble synthetic polymer widely used across various industries due to its biocompatibility, film-forming properties, and solubility. In the pharmaceutical industry, it functions as a binder in tablet formulations to improve mechanical strength and disintegration, a solubilizing agent in oral and topical formulations to enhance the bioavailability of poorly soluble drugs, and a coating material for controlled-release drug delivery systems. In cosmetics, it is a key ingredient in hair sprays, gels, and styling products for its excellent film-forming and fixative abilities, as well as a moisturizer and texturizer for smoother product feel. In the food industry, PVP serves as a stabilizer, thickening agent, and dispersant for ingredients. Its biocompatibility enables applications in medical products, such as wound dressings and contact lens solutions. Additionally, it is employed in textiles as a fiber coating to enhance durability and dye affinity, and in adhesives and printing inks for superior adhesion and binding properties.
