Polyvinylpyrrolidone is a water-soluble, non-ionic synthetic polymer. It is highly versatile with excellent solubility in water and many organic solvents, good film-forming ability, biocompatibility, and adhesive properties. In industrial applications, it is widely used as a dispersant, stabilizer, thickener, and binder. Specifically, in the petroleum additive field, it can serve as a dispersant and viscosity modifier to improve the stability and flow properties of lubricating oils and fuel oils. In the cosmetics and personal care industry, it functions as a film-forming agent, hair fixative, and emulsifier, helping to enhance the texture and durability of products. It also has applications in the pharmaceutical sector as a binder for tablets and a solubilizer for poorly soluble drugs, and in the food industry as a stabilizer and thickener.
