Overview
Povidone (polyvinylpyrrolidone) dissolves readily in water and in alcohols. In wet granulation it is dissolved in the granulating liquid at about 2–5% of the tablet weight and acts as the glue that turns fine powder into strong, free-flowing granules.
The K-value indicates its molecular weight and viscosity; K30 is the standard binder grade. Povidone also improves the solubility of poorly soluble APIs, stabilises suspensions and is the base for povidone-iodine antiseptics. Peroxide content is controlled because peroxides can oxidise sensitive APIs.

Questions
Povidone, answered.
The K-value is a measure of povidone's molecular weight derived from its solution viscosity. K30 has a K-value of 27.0–32.4 and is the standard grade for tablet binding. Higher grades such as K90 are more viscous.
Povidone K30 is typically used at about 2–5% of the tablet weight, dissolved in water or alcohol as the granulating fluid.
Povidone can contain peroxides that oxidise sensitive APIs. Pharmacopoeial limits cap peroxides at 400 ppm, and lower-peroxide grades are available for sensitive formulations.
