The main difference between Povidone K30 and Povidone K90 is their molecular weight and viscosity, which directly impacts their properties and applications. Povidone K90 has a much higher molecular weight and viscosity than K30, making it a better choice for applications requiring superior binding, adhesion, and film-forming properties, such as hair styling and strong tablet binding. In contrast, Povidone K30, with its lower molecular weight, is preferred for applications where good solubility, stabilizing, and lower viscosity are needed, such as solubilizing agents in liquid formulations.
