What is PVP K30 CAS 9003-39-8?

PVP K30 is a synthetic water-soluble homopolymer of N-vinylpyrrolidone, also called polyvinylpyrrolidone or povidone. Its repeat formula is (C6H9NO)n, and K30 grade is typically supplied as a white to off-white hygroscopic powder with an average molecular weight around 40,000 g/mol.

What does the K30 value indicate?

K30 refers to a Fikentscher viscosity value, not a fixed molecular weight. It identifies a medium-molecular-weight PVP grade with a K value commonly around 27-32, giving a useful balance of solubility, binding strength, and viscosity for general-purpose formulations.

What are the main applications of PVP K30?

It is used as a tablet binder and granulation aid in pharmaceutical formulations, a dispersant and stabilizer in pigments, inks, and coatings, and a film former or viscosity-control agent in adhesives and personal care products. It can also serve as a process aid in detergents and cleaning systems.

Is PVP K30 suitable for water-based formulations?

Yes. PVP K30 is freely soluble in water and also dissolves in ethanol, methanol, and other polar organic solvents, so it works well in aqueous binder, coating, dispersion, and stabilizer systems. A typical 5% aqueous solution is mildly acidic to neutral.

How should PVP K30 be stored?

Because it is hygroscopic, store PVP K30 in tightly sealed, moisture-resistant containers in a cool, dry, well-ventilated area. Keep it away from humidity, direct sunlight, and heat sources, and maintain package integrity during transport and handling.
