Povidone pvp k30 is a non-ionic polymer compound
Vidone (polyvinylpyrrolidone, PVP) is used in the pharmaceutical industry as a synthetic polymer carrier for dispersing and suspending drugs. It can also be used as a disintegrator and tablet binder. It appears in pure form as a white to white hygroscopic powder and is easily soluble in water. The molecular formula of POvidone is (C6H9NO) n. Povidone preparations are widely used in the pharmaceutical industry because of their ability to dissolve in water and oil solvents.

​Povidone is water-soluble and its maximum concentration is limited only by the viscosity of the solution. Since it is non-ionic, the viscosity of POvidone in aqueous solution is not affected by pH or salt concentration. Povidone is widely used in solid dosage forms. In tablet preparations, povidone solution is used as a wet granular binder. Povidone can also be incorporated into the powder mixture in dry form and granulated in situ by adding water, alcohol, or a water alcohol solution. Povidone can be used as an oral formulation for dissolution enhancers of insoluble drugs involving processes such as spray drying and hot melt extrusion. 79,89 POvidone is a well-known complexing agent; For example, the ability to compound with iodine is of particular commercial importance, providing antibacterial povidone iodine solutions and powders that are widely used in medical and hospital Settings. Povidone solution can also be used as a film forming agent for coating preparations, or as a binder for layering drugs onto substrates such as sugar or microcrystalline fibrin beads. Povidone is also used as many oral suspensions, stabilizers, or viscosity enhancers. Due to its superior solubility in PEG 400 and glycerol, POvidone is also increasingly used as a viscosifier and stabilizer in liquid-filled gelatin capsules.
