What is Polyvinylpyrrolidone K-90 (PVP K-90)?
Polyvinylpyrrolidone K-90, also known as PVP K-90, is a high molecular weight polymer known for its excellent binding, film-forming, stabilizing, and adhesive properties. It is a white to off-white hygroscopic powder that is freely soluble in water and alcohol, forming a clear and viscous solution.
PVP K-90 is widely used across industries including pharmaceuticals, cosmetics, hair care, personal care, adhesives, and industrial coatings. The “K-value” denotes the molecular weight and viscosity — and K-90 indicates a very high viscosity, making it ideal for applications requiring strong hold, thickening, or suspension.
In cosmetics, PVP K-90 provides a flexible, glossy film, and is commonly used in hair styling gels, sprays, and setting lotions. In pharmaceuticals, it acts as a binder for tablets and capsules. Its excellent solubility and film-forming nature also make it a valuable additive in inks, resins, paints, and adhesives.
